Speculating on a view of the world projected from the perspective of the rock. In the studio drilling more holes for optical lenses set out in a pattern based on the crystal structure of the naturally magnetic mineral magnetite which was determined in 1915 as one of the first crystal structures to be obtained using X-ray diffraction. Found in igneous rocks, sedimentary deposits and sand across the globe in many locations, magnetite is also found in the cells of organisms from bacteria to humans. Magnetite contains both ferrous (divalent) and ferric (trivalent) iron along with oxygen.

Testing projecting through the optical lenses I’m excited to see how the different lenses cause images to overlap and distort.

I received a Digital Microscope for my birthday and a selection of rocks and meteorites to look at. So far I have only used the lens with the least magnification capabilities yet this is revealing wonderful detail in the rocks which are further enhanced by using a polarising filter. I have chosen to look at rocks which originate near areas of tectonic activity or that may have magnetite in them.

Images on left have no filter, those on the right have a polarising filter.

This thin slice of Deep Ocean Pebble was collected in 1979 three miles deep in the Pacific Ocean Clarion Clipperton Fracture Zone. This zone is regularly considered for deep-sea mining due to the abundant presence of manganese nodules. In 2016, investigation of the seafloor in the zone was found to contain an abundance and diversity of life – more than half of the species collected were new to science.

This slice of Lewisian Gneiss is 3 billion years old. These ancient rocks from the Isle of Lewis were caught up in a mountain building cycle roughly 490–390 million years ago and were pushed above younger rocks formed during the late stages of this tectonic event.

This slice of Olivine Basalt comes from Þingvallavatn, a rift valley lake in southwestern Iceland. The area is covered by lava. The cracks and faults around the lake is where the Eurasian and North American tectonic plates meet. This may be the only place where one can stand with two feet on two different tectonic plates. The sample is a mid oceanic ridge basalt (MORB) fine grained but consisting of small olivine, clinopyroxene fragments in ground mass dominated by plagioclase laths, an opaque magnetite.

This slice of Vesicular Basalt Lava – a type of lava that solidifies into a rock with trapped gas bubbles leaving small holes as the lava cools, comes from the Mid Atlantic Ridge near the Azores Islands.

I also have a piece of Jepara taken from a pallasite, a class of stony–iron meteorite, discovered in Indonesia in 2008 during building excavations. The outside is heavily weathered but when cut and polished the inside reveals a translucent structure of densely packed olivine and magnetite. The sample has been coated with acrylic which has surface scratches so I think some of the detail has been compromised but it is still beautiful. No filters used here.

I am making use of public access to historical magnetograms recording of Earth’s magnetic declination to feed into new work inspired by palaeomagnetism. Magnetic studies of the ocean in the 1950’s had determined that the ocean floor was covered by bands of magnetic stripes that varied between normal polarity and reversed polarity. The Earth’s magnetic field has reversed polarity many times over the past hundreds of millions of years. These magnetic stripes were found to be symmetrical on the ocean floor about the mid-oceanic ridge. In 1963 British scientists, Fred Vine and D. H. Matthews proposed that the magnetic striping was caused by paleomagnetism, the storing of Earth’s ancient magnetic field in the sedimentary rocks that were forming as lava spewed up and spread across the ocean floor setting the history of pole reversals in stone.

I have embarked on some crystal growing experiments using a seed crystal in a saturated solution of mono-ammonium phosphate and aluminium potassium sulphate. I am hoping these might become objects to view through a lovely old wooden magnifying box I have. The last time I experimented with crystals was when I was amazed by the speed and glut of salt crystals overwhelming the test area. Before that made a time lapse video over 5 days of crystal growth for the installation Time Crystals in Reading Stones at St. Augustine’s Tower 2019. I will be learning more about this as workshops are developed for The Geological Unconscious public engagement programme which will run alongside the exhibition at Hypha HQ Euston this coming spring. Both Julie F Hill and Sophie Mei Birkin work with crystal structures and growth in their own practices and will be leading on the workshops we will run in partnership with a local primary school.

A crystal is like a class of children arranged for drill, but standing at ease, so that while the class as a whole has regularity both in time and space, each individual child is a little fidgety. Dame Kathleen Lonsdale, 1948

Had some studio fun testing the possibilities of magnetic putty for future video ideas. Mesmerising the way it very slowly swallows the magnet.

I began the magical process of making copper ink. Soaking pieces of copper in vinegar and salt, stirring daily and watching the liquid turn a milky turquoise blue. Looking forward to using this to patinate copper but also to paint with on paper.

Experimenting winding a copper wire around an iron nail and connecting the wire to a battery cell. A magnetic field is generated around the nail which stays for a little while after the nail is removed from the coil. I used a 9v battery and large nail– it wasn’t a very strong magnet – a welding stick was better and seemed to retain the magnetic field for longer but in both cases the battery got very hot. I had hoped to maybe develop this idea to magnetise a sculpture threaded with iron. Needs more investigation.

I have been exploring the updated Digital Materials Library at the Institute of Making which led me to the Mindsets website which has some cool magnetic materials for sale. Future experiments upcoming.

Exploring paper weaving patterns with a view to reinventing past works while thinking about ideas of cosmic planes in The Rosicrucian Cosmo-Conception, a 1909 text by Max Heindel. This text, setting out a theory of seven Worlds and seven Cosmic Planes, supposes an intermingling of spirit with matter where the intersection of the material and metaphysical world are not one above another in space, but inter-penetrate each with the other.

Astonishing that the preserved remains of the ancient kauri trees of New Zealand, alive over 42,000 years ago, can reveal the time of the last significant magnetic pole excursion within their rings. During what is known as ‘The Laschamps Excursion’, the north and south magnetic poles swapped places for about 500-800 years before swapping back again. During a magnetic pole reversal the magnetic field weakens so many more cosmic particles reach the surface of Earth. This means much more Carbon-14 is produced in the atmosphere and absorbed by plants.

Changes in radiocarbon levels were recorded from four ancient kauri logs found buried in peat swamps which seals them in a chemically balanced environment. Through high precision carbon dating processes at the University of Waikato in New Zealand the scientists discovered the most dramatic time was the lead-up to the reversal, when the poles were migrating across the Earth and our magnetic field practically disappeared, leaving life here very vulnerable to cosmic radiation. It appears, this weakening 42,000 years ago, in combination with a period of low solar magnetic activity – captured in evidence from ice cores, caused damage to the ozone layer and disrupted atmospheric conditions impacting the global climate so that devastating environmental changes took place. The research team links this climate change to extinction events which occurred at the same time, Neanderthals vanishing from Europe, and a proliferation of cave paintings appearing in Europe and Asia as humans find shelter from the turbulent weather and increased electrical storms. They have dubbed this period of excursion ‘The Adams Event’ in honour of Douglas Adams who wrote in The Hitchhikers Guide to the Galaxy that ‘42’ was the answer to life, the universe, and everything

Studio Visits

Julie F Hill and I have been visiting the other artists participating in the upcoming exhibition The Geological Unconscious at Hypha HQ Euston. We are so happy to be working with Charlie Franklin who considers control, physical experience and memory within the natural landscape, Deborah Tchoudjinoff who considers what the form is through the process of material and visual experimentations, Rona Lee who centres on the politics and aesthetics of Geo-materiality along with the human /more than-human entanglements of contemporary life and Sophie Mei Birkin who investigates the generative potential in the transformation of matter through a variety of material processes such as growing salt crystals and exploring amorphous and decomposing substances.

I have also been lucky to have Charly Blackburn and Victoria Rance visit my studio to chat about our respective work and shared interests. Charly is beginning a period of research into rare earth materials and extractive processes and we share a fascination with things magnetic. Victoria came to chat about our shared interest in the sun but is also interested in magnetic fields and the potential they offer for brain to brain communication.

Gallery Visits

Haegue Yang Leap Year at Hayward Gallery. With colourful works festooned by garlands of bells and strewn with fairy lights this was a perfect show for the festive period. Folklore, surrealism and ritual, collage and costumes combine with the modern domestic/utilitarian in hybrid works that have a playful carnival air.

Thoughtful works beautifully presented Each Place Its Own Mind at Edel Assanti with Mirtha Dermisache | Noémie Goudal | Sky Hopinka | Anna Hulačová | Marguerite Humeau | Bronwyn Katz | Kat Lyons | Yukultji Napangati | Emmanuel Van der Auwera. An ongoing collective reimagining of our relationship with the living world, rooted in revelations from indigenous knowledge, ecological research, literature, science, and artistic experimentation. Each Place Its Own Mind  borrows its title from ecologist David Abram’s 1996 book The Spell of the Sensuous, which traces the ways the human mind came to renounce its “sensory bearings” in the natural world, visualising a myriad of “lost” faculties that link the “inner, psychological world and the perceptual terrain that surrounds us.”

Events

A little out of my depth at the A&G Highlights Meeting at The Geological Society where some talks were quite specialised, involving graphs and terminology beyond my understanding. I do enjoy hearing clever people talk though, even if I can’t grasp exactly what they are explaining. A fascinating presentation by writer Nilanjan Choudhury on ‘The Square Root of a Sonnet’, his play which explores the fraught personal relationship between the brilliant Indian-American astrophysicist Subrahmanyan Chandrasekhar and his mentor, Sir Arthur Eddington of Cambridge University who publicly humiliated him at a Royal Astronomical Society meeting 90 years ago to the day. Guardian Article here

Dr Jessica Irving (Bristol University) gave The Harold Jeffreys Lecture on ‘Hearing planetary hearts: seismology of the cores of Earth and Mars’. An engaging speaker, she led us through the milestones of the last 130 years of theories on what is at the centre of the Earth and the discoveries made using seismology.

Dr Chris Lovell (University of Portsmouth) spoke on his research into ‘Accelerated modelling of the entire observable Universe’. I recognised the dark matter simulations and was fascinated by the different views of a galaxy depending on the band of the light spectrum used to observe it.

I joined a sobering Royal Astronomical Society webinar We Need to Talk About Space Junk presented by Professor Mike Lockwood. Our use of space is increasingly limited and threatened by space junk. The concern is that we are heading towards a runaway effect called the Kessler syndrome, in which the debris from one collision causes many others, to the point where space becomes unusable.

I went to see the fast paced RSC production of Kyoto at Soho Place. Welcome to the Kyoto Conference Centre, 11 December 1997. The nations of the world are in deadlock and 11 hours have passed since the UN’s landmark climate conference should have ended. Time is running out and agreement feels a world away. The greatest obstacle: American oil lobbyist and master strategist, Don Pearlman… Set nearly 20 years ago its depressing how little progress was made and we are currently sliding backwards. Would never have guessed it at the time but now am nostalgic for the politics and positivity of the 90’s.

Time to email your MP to join The All-Party Parliamentary Group for Dark Skies. The group’s primary focus is to preserve the night sky within the UK and promote the adoption of dark sky friendly lighting and planning policies. Surprisingly the committee is made up mostly of tories – come on the rest of you!

Go to this link where it is quick and easy to message your MP to act on this important issue.

Watching Chris Packham’s The Wonder of Animals – Foxes A red fox catches its prey using more than pinpoint hearing and an accurate pounce: it also involves alignment to the slope of Earth’s magnetic fields. I contacted Peter Hore FRS, Professor of Chemistry and Magnetoreception expert at Oxford University who was so helpful to me before in explaining how birds ‘see’ the magnetic field to see if he had come across any new research on this. He has pointed me in the direction of other research conducted by the group looking at fox behaviour so this is something I will pursue further.

Listening to What? Seriously?? with special guest Helen Sharman, the first British astronaut, about how humans learned to survive in space. Quite a few animals were sent to space before humans including two Russian Steppe tortoises (Testudo horsfieldi), who did a circuit of he moon and returned to Earth – alive but starved. The tortoises were chosen as they have a unique ability in the animal world to resist radiation and their blood may be useful in the treatment of radiation sickness. In recent research a string of amino acids have been extracted from the blood of these tortoises and if you inject those amino acids into other animals they become radiation resistant too.

Listening to The Year in Science 2024 podcast – One of the UK’s first military communication satellites’ Skynet 1a launched in 1969 was abandoned a few years later above Africa. Orbital dynamics should have dragged it out somewhere above India but it has been found wandering above the Americas in a busy area of live satellites and no-one knows why. Space consultants think it must have been commanded to move in the 1970’s but can find no record of this and although research has been undertaken it is still a mystery how this satellite moved. BBC article

There is no mention of a cosmic ray interaction forcing the command, but that would be my theory!

I am extremely grateful to a-n Artists Newsletter for the professional practice and creative development bursary that allowed me to visit Kielder Observatory in Northumberland and Eskdalemuir Observatory, Dumfriesshire to research how space weather impacts Earth’s magnetic field. I am also grateful to Claire Brown, site manager at Eskdalemuir Magnetic Observatory, for her time showing me around the site and explaining the many measurement processes that happen here. Despite the first survey of the site at Eskdalemuir, by the National Physical Laboratory in 1903, reporting back that “the weather was wet and stormy, and somewhat unfavourable to “field work” an observatory was established in this remote location, and recordings monitoring Earth’s magnetic field have been made from this site for 120 years.

I was able to visit the East Absolute Hut, the Underground Chamber, and the Seismic Vault along with the main building and museum rooms. The interaction of space weather with magnetic currents in the surface of the Earth is monitored here, and there is a camera on the roof to record visual aurora on a loop which is then sent to the British Geological Survey research teams in Edinburgh for analysis. Meteorological observations are also made here, along with solar radiation, atmospheric pollution, and seismological activity. The monitoring of radiation pollution was inaugurated here after the Chernobyl incident in 1986 when explosions at the nuclear plant scattered radioactive elements over a wide area across Europe.

95% of Earth’s magnetic field comes from the swirling outer core of the Earth and changes are due to convection pattern turbulence. As compasses have been used for over 400 years, and records kept of magnetic declination, there is a long history of measurements to refer to. The magnetic north pole had been drifting westwards at about 55km a year up until 2020 but has recently slowed to 45km. Consistency of observations is very important for magnetic field modelling, which is why many of the instruments at Eskdalemuir are located underground to maintain an even temperature.

Manual observations of the direction of the magnetic field are taken once a week from the East Absolute Hut. A small sliding window in the wooden hut is pulled back to reveal a distant fixed azimuth mark, not always easily visible during inclement weather. The mark, viewed through the fluxgate theodolite, must be lined up with the north south meridian line until the reading on the digital recorder is at zero. At the same time the digital clock must read zero. These numbers fluctuate rapidly but once both machines read zero a measurement of the position of the magnetic north pole can be recorded. A separate recording is taken through a series of 12 angles on the theodolite to give an accurate position. The instrument is very sensitive and the operator wears the same clothes each time with no metal fixings etc to ensure consistency in the records. The measurements are then plotted on a graph which usually follows a smooth line describing the drift of the magnetic north pole. Sudden deviations alert the operator to errors in the recordings or dramatic movement in the field known as a geomagnetic jerk.

The instruments in the underground chamber measure the strength of the magnetic field in three directions.

Surface readings are also taken automatically from instruments in small enclosures in the back field. During my visit these instruments were used to record data rather than those I came in close contact with.

In the vault, seismograph readings are made of vibrations in the bedrock. Seismic activity around the UK is fairly low level but sensitive structures can still be effected. These instruments pinpointed the magnitude 4.7 Longtown earthquake on Boxing Day 1979, and a swarm of tremors in the Dumfries area in 2001. The network also detected the air crash at Lockerbie in 1988, accurately recording the time of impact for crash investigators.

The museum holds a wonderful collection of mysterious instruments.

I attended Aurora Night at Kielder Observatory, established in 2008 under some of the darkest skies in Europe, to learn about how solar activity interacts with Earth’s atmosphere and creates the Aurora. The skies were very dark but also cloudy, and the sun was quiet, so no chance of seeing any aurora or even stargazing. However, we were given fascinating presentations on what causes the ethereal coloured lights seen at Earth’s poles and further towards the equator when solar activity is peaking.

We were also given some cool meteorites to handle including a carbonaceous chondrite, one of the most primitive objects in our solar system.

The sun rotates faster at the equator than at the poles and this causes disruption in its magnetic field. The solar flares that we see loop out from the surface of the Sun are caused by localised incidents of polarity, where plasma and particles loop around what could be thought of as areas acting like independent bar magnets. Millions of tons of plasma and chunks of magnetic field can be ejected during one coronal mass ejection and this matter hurtles out into space, if we are in the line of fire we will be bombarded with energetic particles and Earth’s magnetic field will be disrupted. The solar wind brings the particles from the Sun that envelop Earth and are drawn to the polar regions by the geomagnetic field. The aurora is caused by the interaction of these high energy particles (usually electrons) with neutral atoms in the earth’s upper atmosphere. The particle collisions that occur in the upper atmosphere cause photons of light to be emitted. The Earth’s geomagnetic field is not symmetrical and changes as the Earth rotates, it responds to the disturbance of particles coming from the Sun and as the field adjusts to this disturbance, magnetic energy is released, thereby accelerating charged particles to high energies. These charged particles are forced to stream along the geomagnetic field lines which is why the aurora lights can appear in vertical columns or other dancing shapes depending on where in the magnetosphere they entered the atmosphere. The colours of the lights are dependent on which atmospheric gas is being excited by the solar particles, oxygen emits either a greenish or a red light and nitrogen gives off a blue light.

Solar activity is monitored and space weather forecasts are posted online. To be in with a chance of seeing the Aurora in the UK, the KP level should be 5 or above as this index increases as the aurora’s southern edge moves southward. It can take up to three days for the particles ejected from the Sun in a CME to reach the Earth. The lights are fainter than sunlight so a dark night sky is needed to see them. It is also often the case that the greater photo sensitivity of a camera can capture lights that are barely visible to the human eye. The aurora is more likely to be visible during the spring and autumn equinox because of the angle of the Earth’s magnetic field in relation to the Sun, not because storms are more frequent.

2024 is predicted to have a high number of solar storms so there may be opportunities to see the Aurora but it also comes with the risk of severe space weather that could cause havoc with our reliance on satellites and related technologies.

The connection between solar activity and the impact on technology was made during the 1859 Carrington Event, the most intense geomagnetic storm in recorded history. Strong auroral displays were reported globally and even seen in London, while sparking and fires occurred in multiple telegraph stations.

Satellites are vulnerable to space weather which can cause ongoing degradation or single event upsets where a charged particle can trigger a command in the satellite. During space weather events the ionosphere can become enhanced making it harder to communicate with satellites. Errors can occur in precision navigation and timing situations. Aviation crews are at risk to higher doses of radiation during solar activity and the HF radio communication system can have interference. Induced geoelectric fields in the ground can cause currents to flow in power grids and railway lines damaging transformers.

During the 2003 ‘Hallowe’en’ solar storms, when the largest single solar flare ever recorded was followed by severe storms, over half of all Earth-orbiting spacecrafts were impacted, disrupting satellite TV and radio services, GPS systems, damaging a Japanese scientific satellite beyond repair, sending several deep-space missions into safe mode or complete shutdown, and destroying the Martian Radiation Environment Experiment. The solar storms also led to communication problems for flights passing over the North Pole and Antarctic science groups had a full communications blackout for several days.

In acknowledging these risks we can gain an awareness of our vulnerability to the forces of nature and a respect for the power of the sun, the protection offered by our home planet and the interconnectedness of the universe.

Life Boat at APT Gallery

Life Boat brings together artists with a shared interest in exploring precarity as a site of dynamic transition. Each takes an investigative approach to the environmental, social and historical themes evoked by the lifeboat, as a means of addressing ecological crisis, liminal landscapes, close and distant horizons, boundaries and displacement, lines of rescue, navigation and transformation.

Very happy to be exhibiting with Rachael Allain, Caroline AreskogJones, Beverley Duckworth, Liz Elton, Kathleen Herbert, Kaori Homma and Anne Krinsky.

We had a fantastic opening night.

I was showing submīrārī (earthbound) and a new video installation Orbital – these works both consider transient landscapes, ecological landscapes on the cusp of disappearance and the digital landscape at risk from obliteration by an extreme solar storm.

submīrārī (earthbound), 2018, steel, earth, water, sublimation printed textile, 12 pieces dimensions variable approx. 200 x 200 cm. Reflections of a no longer certain world hover in pools fluctuating on the cusp of disappearance. The ethereal images float or submerge revealing the hidden activity of water which also refracts light across the surface prompting the viewer to repeatedly shift perspective. Donna Haraway, drawing from Latour, proposes the ‘Earthbound’ as those humans who are ready to rethink and create new narratives with Gaia at the centre, who recognise the entanglement of society and nature and aim to pursue a ‘nonarrogant collaboration with all those in the muddle’. The shift in perspective embraced by the ‘Earthbound’ embodies a grief shared with other species at loss of habitat and disappearing landscapes. It is not a nostalgia for paradise lost but a reappraisal of what paradise could be.

Orbital, 2024, Back projection video, mini screen array, board, installation 122 x 200 x 50 cm, video 05:44 min. An exploration of the potential risks of space weather on human technology and infrastructure and non-human navigation.

The Sun is about 150 million kilometres (93 million miles) from Earth, but space weather can affect Earth and the rest of the solar system. It can cause damage to satellites and electrical blackouts on Earth. Small satellites have come to dominate low Earth orbit, and we have become reliant on this technology for communication, military strategy, and data gathering.

A blast of high energy particles hitting Earth during a solar storm can interfere with Earth’s magnetic field, confusing birds that use this for navigation. In America, pigeon racers postpone the big race if bad space weather is predicted. There is also new research that might suggest the number of satellites orbiting Earth and the growing satellite space junk graveyard could weaken Earth’s protective magnetic field, making us even more vulnerable to space weather and cosmic radiation.

Rachael Allain’s current doctoral project ‘Above and Below the Horizon: A practice-led investigation into liminal thresholds of bodies of water’ has been undertaken in response to various aquatic locations. The work shown in this exhibition documents mapping aspects of an unexpected journey of discovery made in the upper reaches of the Arctic Ocean during an international art and science expeditionary residency in the Svalbard Archipelago during midsummer 2022. ‘Circumnavigation of a ‘Bergy Bit’’ is a film with sound of a close and intimate encounter with a section of an iceberg, calved from its mass and found beached and melting close to shore in Eolusneset, Sorgfjorden in the Bay of Grief.

In 2019 Caroline AreskogJones spent time on the Sea of Hebrides making a series of responses whilst researching more viscerally the ocean as a site of ‘field research’ and gathering recordings. ‘Sounding Line’ (2024, sail, audio/video single channel as projection 07:32 min. Sail courtesy of Sail Britain) was created in deliberate wave format being inspired by Jean Painleve, whose hybrid films overlaid with jazz soundtracks occupy the uncertain space between art and science. Oskar Jones was invited to create the sonic composition in response – the saxophone being a wind instrument of extraordinary virtuosity.  Since 2023 Caroline has been visiting the Natural History Museum Cetacean Archive – at the invitation of Principal Curator, Richard Sabin. Through conversations including those with environmental historian Sophia Nicolov, her research has broadened and this updated presentation includes recordings of the two remaining Orcas who inhabit the Sea of Hebrides courtesy of the Hebridean Whale and Dolphin Trust.

Anne Krinsky Boiling Seas Acid Seas (Work-in-progress), 2024, Video, 12:26 min, filmed on location at Long Beach Peninsula in the Pacific Northwest.

A History Of The Receding Horizon (2015, HD Video, 16:9, sound, projection, 28 min) is a digital film installation by Kathleen Herbert, exploring different concepts of time within the landscape. Based upon Kielder in Northumberland, the narrator whose script was developed from the artists research interviews with environmental historians, astronomers at Kielder Observatory and local people from the area, leads the viewer through the film weaving together past, present and future timelines. The Chaplin (2006,  standard HD video, 4:3, sound, monitor, 07: 20 min) is a film installation recalling a conversation held between the artist, Kathleen Herbert, and the Port Chaplin based at the Mission to Seafarers centre in Avonmouth docks. The Port Chaplin boards every ship as it enters the docks, his role is to provide emotional and practical support to seafarers while they are in port. The piece was produced while Kathleen was based at the centre researching for a new commission by Picture This Moving Image and Situations Bristol. Her research at the centre culminated in a 3 day voyage aboard a cargo ship in which she took her camera and the extracts of film from this journey provide the visual background of the film.

Fragility and vulnerability are embodied in layered works on paper, a large suspended sculpture made from delicate compostable material and living installations incorporating transient elements that transform over the exhibition period.

Anne Krinsky has been working on a research-based project about vulnerable wetlands and climate change since 2018. Coastal wetlands worldwide are at risk from rising sea levels caused by climate change, while inland watersheds are threatened by heat, drought and agricultural runoff. These ecosystems are critical to the plants and animals that inhabit them and to human survival. She is drawn to biodiverse habitat edges – where water meets land or where fresh water meets the sea and is interested in recording both the beauty of – and human impacts on – fragile habitats. She uses documentation as an archive of raw materials to generate work in other media, including site-responsive print and video installation and tactile work on paper. In responding creatively to wetlands and watersheds, she wants to raise public awareness of climate threats to these life-sustaining habitats. Before They Vanish, 2024, 24 small works: paper, mylar, acrylic, digital print, mixed media, 150 x 300 cm.

Caroline AreskogJones Float 2023, Paper lithography on shoji, 60 x 120 cm forms part of a series of works inspired by the Natural History Museum Cetacean Archive, rendered onto Shoji paper, used in museum conservation.

Liz Elton begins in landscape and still-life painting to explore the potential of waste and the recycling of matter.  Her ephemeral work is often made on compostable ground, coloured with kitchen waste and embedded with seeds. Showing Habitat, 2024, Compostable cornstarch food waste recycling bags, household textiles from a house clearance, vegetable dyes from kitchen waste, water colour, silk, soil from various locations and gleaned from vegetables bought in the market, vegetable seeds saved from food preparation, seeds of varieties of self-seeding edible plants typically found on the wasteland around Deptford creek, found wood, Approx. 360 x 250 x 150 cm (variable).

Working with living sculpture and installation, Beverley Duckworth creates spaces and moments which connect the smallest, poetic actions of plants with precarious issues facing humanity. Her practice centres on the afterlife of the discarded and is rooted in small acts of reparation – sewing scraps together, watering fragile seedlings and nurturing the regenerative power of composting from waste materials. Works include Husk, 2024, Discarded cardboard, thread, flax, seeds, water, 90 x 70 x 280 cm; Raze, 2023, Discarded clothes, binder, 48 x 51 x 10 cm.

Etchings and spatial interventions explore the use of the natural world as human resource and land as a site of geopolitical conflict.

Kathleen Herbert Lost Dimensions I, II, III, 2022-23, Photopolymer Etching on Somerset Satin Paper, 75 x 57 cm.

Kaori Homma’s multi-site Homma Meridian project asks us to reconsider and to challenge the cartographic demarcations that govern so much of our world and that we so frequently take for granted. With the deceptively simple move of ‘repositioning’ the Greenwich Prime Meridian, the artist radically shifts our perspective, as well as our sure footing, both figuratively and even literally. At each of its iterations (which have included Budapest, Margate, Wales, Paris, London and Pennsylvania) the artist and participating audiences draw an impermanent line running north-south, always using ephemeral materials, as a substitute for the ‘Prime’ meridian. The project’s act of displacement and its ephemerality work to highlight the imaginary nature of boundaries and to shake up our perception of our position on the earth as it spins on its titled axis. Works include Homma Meridian, Deptford, 2024, Vinyl Letters, tape, dimensions variable; Floating 0 degree Longitude, 2024, Abrudashi Fire Etching, Water, Bucket, 60 x 38 x 25 cm; Four corners of the earth, 2024, Aburidashi Fire Etching on Paper, 50 x 80 x 3 cm

Alongside the exhibition we held a series of events including a Low Tide Walk in Deptford Creek – led by Anne Krinsky in partnership with Creekside Discovery Centre followed by refreshments and a tour of the Life Boat exhibition at APT Gallery just two minutes from this amazing natural habitat in Deptford.

FIELDWORK AS PRACTICE – A live sonic performance by Oskar Jones and a conversation led by Caroline AreskogJones bringing together Oliver Beardon (Founder and Skipper of ‘Sail Britain’) Richard Sabin (Principal Curator of Mammals at the Natural History Museum, London) and Sophie Nicolov (AHRC Early Career Research Fellow, Natural History Museum, London) for a discussion around the potential overlaps between ‘field’ and research, artistic practice and ecological activism.

Homma Meridian and the Secret of Invisible Ink/Fire Etching Workshop where Kaori Homma shared her technique using Invisible Ink as part of the Aburidashi/Fire Etching process, historically used for espionage, she also gave a fascinating presentation on the history of this process and how it relates to her own art practice and her Homma Meridian Project.

In tackling concepts of the perilous, the vulnerable and the lost, Life Boat raises the alarm on the passive position of waiting for rescue and encourages urgent action in troubled waters.

Women In Revolt at Tate Britain. A lot of documentation here of social history. Many texts, posters, zines, not so much art but a great piece from the inimitable Susan Hiller, with personal incites accompanying images of her ever increasing pregnant belly such as: – She writes, one is born into time. And in time introduced to language….Or rather — one is born. And through language, introduced to time…Perhaps even — one is born, in time, through language.

A webinar from British Geological Survey on how we measure the magnetic field, everyday applications and mitigating the threats of space weather. From the Earth’s core to outer space: understanding the magnetic field

‘A stone sky rotated above our heads’ – Italo Calvino, Cosmicomics

The culmination of two years work – A STONE SKY duo exhibition with Julie F Hill opened at Thames-side Studios GalleryReimagining the idea of an observatory – the exhibition proposes a cavernous realm of real and speculative possibilities that arise from beyond the limits of human perception. Engaging with the extended sensory range offered by technologies such as orbiting space telescopes through to the ability of birds to ‘see’ the Earth’s magnetic field, the artists’ reveal intimate connections between earth and space.

Susan Eyre seeks to navigate a path across time from the first human encounter with the magical qualities of the lodestone to current understanding of the interaction of the magnetic field with terrestrial life. Her works respond to the architecture, instruments and materials, found at a magnetic observatory while scientific objectives are expanded to include natural navigation techniques and extra-sensory methods used by the non-human realm, to form the basis of speculation as to the ability for humans to perceive the Earth’s magnetic field. Installation, sculpture and moving image works include a reimagined observation hut operating as a sensory hub with video screens suggesting portals into a web of neural pathways; an obelisk of layered recycled paper echoing Earth’s geological and magnetic history secreted in sedimentary strata of rock and a digital video work activated in real time by the passage of cosmic rays through a scintillator detector.

Julie F Hill explores the entwined darknesses of earth and cosmos. Crystalline and mineral substances from the deep earth fuse with astronomical data to suggest the deep-earth as an instrument for coming to know the cosmos. Crystalline and mineral substances formed in the continuum of deep earth and deep space allow us to peer back into cosmic time, both through the technologies created with them and the geological record they hold. Whilst darkness often indicates uncertainty and lack of knowledge, Hill asserts that it’s through darkness when we can be most perceptive to the interconnectedness between earth and cosmos. Through it we are able to extend our kinship with the inorganic and expand consciousness of what constitutes nature. Works include a large-scale sculptural print installation made from James Webb Space Telescope data that is reworked into a cavernous space, providing an experience of intimate immensity alongside more smaller sculptural and photographic works.

We both had ambitious large scale works to install and were grateful for the help we received from our partners (both Kevins), friends and technicians. Trevor Neale was magnificent in constructing The Absolute Hut. Anne Krinsky patiently helped apply double sided tape to the roof structure ready for the Suminagashi paper tiles and Caroline AreskogJones energetically painted the hut white and neatly edged the two way projection window. I was thrilled that, as a result of a wet few weeks, moss had started to grow on the wooden boards of the north facing wall in time for installation.

A big thank you to everyone that made it to the opening night, we were super chuffed with the positive responses.

At the private view Julie’s large scale print installation was activated by a vocal performance conjuring abyssal voices of deep, cosmic time, performed and devised with Eleanor Westbrook whose voice produces incredible hauntingly beautiful sound.

I was particularly excited to share The Breath of Stars, digital video work activated in real time by the passage of cosmic rays through a scintillator detector. After two years in development it was so exciting to watch the random starbursts appear in real time as witness to the unseen activity of cosmic rays passing through the gallery.

The kaleidoscopic video images that appear for every particle recorded by the detector, are created from footage of cosmic ray trails filmed in a cloud chamber.

The interaction of cosmic rays with atmospheric electrical fields influences the unpredictability of the magnetosphere and this random activity can be witnessed by the sudden flurries and silent gaps of the live video imagery.

These subatomic visitors from outer space power across the universe with unimaginable energy, coming from the heart of exploding stars or the depths of black holes; some may come from phenomena yet to be discovered or even from other dimensions. Travelling at close to the speed of light cosmic rays spiral along magnetic field lines, strike the edge of the Earth’s atmosphere, break apart and shower down upon us. Some particles collide and silently interact with atoms and technology on Earth. Most cosmic rays heading for Earth are deflected by the planet’s magnetic field and without this protection life on Earth could not survive this bombardment of radioactive matter. The interaction of cosmic rays and the solar wind with atmospheric electrical fields combines to influence the unpredictability of Earth’s magnetosphere, impacting the functioning of GPS satellite technology and computer processors on which humans have come to rely in daily life.

My research trip to Hartland Magnetic Observatory in North Devon was a catalyst for this body of work centring around a north facing observation hut aligned with an obelisk as a fixed azimuth mark. I am very grateful to The British Geological Survey for allowing me access to the site and particularly to Tom Martyn who shared his knowledge and gave a fascinating tour of the observatory.

The Azimuth Obelisk (of sedimentary knowledge) is a reimagining of an obelisk erected at Hartland Magnetic Observatory in the late 1950’s near the site’s northern boundary. Viewed through the window in the north wall of The Observing Building (also known as the Absolute Hut) it acts as a permanent azimuth mark from which the drift of the magnetic north pole is monitored. Currently almost hidden by undergrowth, the observatory’s concrete azimuth mark has been replaced by a digital GPS position. Much as the Earth’s geological and magnetic history is secreted into the strata of sedimentary rock, this sculpture also expresses the passage of time through the layering of recycled paper prints and drawings whose history becomes embedded within the stacked layers.

The Absolute Hut (of action potential) operates as a sensory hub with video screens suggesting portals into a web of neural pathways where a range of actions and processes are running concurrently reflecting on the dynamics between the Earth’s geologic structure and navigation using the magnetic field.

The title refers to the way neurons send information electrochemically around the body. The signals they send are called action potentials which is a temporary shift from negative to positive within the cell caused by certain ions entering the cell. Action potentials can be triggered by an interaction with the magnetic field causing a reaction in the body.

The installation is conceived from a combination of features, impressions and functions of the observing building and instruments at Hartland Magnetic Observatory in North Devon and the observation huts built in the 18th century at The Kings Observatory in Kew for meteorological and magnetic observations.

Topological contours of suminagashi marbling and plasma cut copper reflect the fluid motion of the Earth’s molten iron core and the pulsating alpha waves of the human brain when subjected to magnetic fields.

‘the internal skies have their own birds’ Italo Calvino Cosmicomics

The fascinating and perilous journeys made by migrating birds has been a natural wonder for centuries with the first records of this phenomena made more than 3,000 years ago. The innate knowledge of migratory birds is mentioned in Job and Jeremiah and the ancient Greek writers Homer, Hesiod and Aristotle noted their passage.

Job 39:26 Doth the hawk fly by thy wisdom and stretch her wings towards the south?

Wintering light two way video projection of migratory pink footed geese filmed at RSPB Snettisham on the North Norfolk coast.

Research has proven that birds and many other animals can use the earth’s magnetic field for navigation. There are two ways this happens. In birds there is a protein in the retina of the eye – (cryptochrome molecules) which trigger action potentials enabling them to visualise the magnetic field. In other animals and magnetotactic bacteria tiny crystals of magnetite respond to the field. This may also be true of humans as we do have these crystals in our brain cells.

Birds use three different compasses to navigate across the globe; the sun, the stars and the magnetic field.

Birds are also able to detect rapid movement such as individual flashes or flickering of a fluorescent light which humans see as a continuous light. Hawks which pursue other birds through dense forests at high speeds, follow the movement of their prey while avoiding branches and other obstacles. To humans travelling at this speed, the fleeing prey, branches and obstacles would just be a blur.

Degrees of Variation considers what it might be like to have the sensory powers of a bird where a protein in the eye is excited by polarised light making it possible to see the magnetic field and follow a visual navigatory cue in an accelerated world. The video imagines flight over water and through woods while being guided by the force of a magnetic field.

Calvino’s story The Stone Sky is wonderfully descriptive of the volatile geological structure of the Earth. This fluidity is what makes life on Earth possible. Only planets with fluid cores have magnetic fields. The geological interior generates a field that reaches into outer space offering a protective shield.

internal skies : external spheres video sequences within concentric circles mimic the geological structure of the Earth to explore the relationship between Earth’s magnetic field and various methods of navigation including via magnetoreception and celestial observation. Sequences include star trails around Polaris (the current north star), birds and bees that use the magnetic field for navigation, magnetotactic bacteria, magnetised iron filings, aerial views of the coastline around Hartland and early morning polarised light which excites the cryptochrome protein in a birds eye.

The Earth’s geomagnetic field is created by a combination of three separate fields and timescales. The main field is generated in the earth’s molten iron core.  Observing the field gives clues to the planet’s deep interior which is inaccessible to direct observations. Changes are measured in the annual drifting of magnetic poles. Secondly electrical currents caused by solar weather and cosmic rays bouncing off the Earth’s main  field charge the surrounding ionosphere causing fluctuations in the field. This field changes by the micro second as we orbit the sun. The Earth’s magnetic field also acts as a shield against most potentially harmful charged particles from outer space. Finally the residual magnetisation of the geology of the rocky mantle and crust, measured in deep geological time also offers clues to the geological history of Earth.

The understanding of the world surrounding us forms in the darkness of our skulls. 

interference – a panel of 12 small video screens inside The Absolute Hut (of action potential), showing images of the human brain filmed by using polarizing filters to create pulsating birefringence colours, relate to the narrative pinned to the outside of the hut.

The narrative is a mix of fact and fiction based on a real experiment carried out at Caltech where scientists found Alpha waves in the human brain do respond to Earth’s magnetic field and other research suggesting that it could be possible for the magnetic field in one animal’s brain to transmit information to another animal’s brain by triggering action potentials creating the same thoughts and emotions.

Instruments of the Anemoi are a set of dodecagon tablets cast in Snowcrete, a non-magnetic cement, as used in a magnetic observatory. Suggestive of the pedestals that support various instruments used in monitoring the Earths’ magnetic field they also respond to an ancient anemoscope “table of the winds” carved in marble around eighteen hundred years ago and inscribed with the Greek and Latin names of classical winds on each of its twelve sides. Envisaged here as speculative objects, instruments and schematics wrought by the wind gods, the first emissaries of navigation and orientation.

One tablet holds a copper bowl with a ‘silver fish’ floating in water. The shape of the ‘silver fish’ is based on the oval shaped compass needle (illustrated in Breve Compendio de la Sphera de la arte Navegar by Martin Cortes 1551)  and refers back to wafer thin fish shaped iron leaves used by 11th century Chinese geomancers.

Nails and iron filings on the second tablet reveal an embedded magnetic field recalling a legend that the discovery of the lodestone was made by a Greek shepherd who noticed the nails in his boots were attracted to the rock (magnetite) beneath his feet.

The third tablet is embedded with copper etched with images and names based on associations and attributes of the twelve Greek wind gods set in a traditional compass rose.

Domain of the Devil Valley Master uses industrial directional magnetic steel, sanded and etched to reveal the Goss texture of rolled iron silicon alloy crystals. The jigsaw pattern of magnetic domains give this material exceptional magnetic properties. The simple evocation of a spiral described in geologically informed polygons draws upon many references, from the shape of our own Milky Way Galaxy sculpted by vast cosmological magnetic fields and the spiralling molten dynamo generating Earth’s magnetic field, to the inner pathway of spiritual growth and the route to the symbolic omphalos (navel) at the centre of the world where the sky entrance and the underworld meet. The title of this work originates from an ancient Chinese manual on the skills of persuasion, The Book of the Devil Valley Master, containing the first known mention of a compass, known at the time as a south-pointer.

The exhibition closed with an afternoon event launching our publication which includes the essay Dark Nights and Signs of Unseen Things by Anjana Janardhan. There was also a live cloud chamber demonstration of mesmerising cosmic ray trails, artist tours and informal readings.

Photoshoot with Warren King Photography resulted in some great images of my work ready for the press release and promotion of A STONE SKY – the upcoming joint exhibition, with Julie F Hill, that we have been working towards for many months. The exhibition will be at Thames-side Studios Gallery 11th – 26th November 2023 with a private view on 10th November 6-9pm.

A Stone Sky brings together the works of multi-disciplinary artists Julie F Hill and Susan Eyre who traverse cosmic layers from the deep earth to deep space, exploring manifestations of darkness and its associations with the unknown and undiscovered. Reimagining the idea of an observatory, their sculptures and installations reach for scales and orders that surpass the human, revealing the cosmic at our feet. The exhibition proposes a cavernous realm of real and speculative possibilities that arise from beyond the limits of human perception. Engaging with the extended sensory range offered by technologies such as orbiting space telescopes through to the ability of birds to ‘see’ the Earth’s magnetic field, the artists’ reveal intimate connections between earth and space.

It was great to meet Anjana Janardhan who we have commissioned to write an essay for a publication which will be launched on the final weekend of the exhibition. We are also planning to give some informal readings, tours of the work and I will be running the cloud chamber so visitors can see the trails of cosmic rays – a way of visualising these unseen visitors from the stars.

The Azimuth Obelisk (of sedimentary knowledge) sculpture is an almost 3m tall reimagining of the obelisk erected at Hartland Magnetic Observatory in 1955 as an azimuth mark to be viewed from the Observing Room or Absolute Hut to monitor the drift of the magnetic north pole.

I have obtained an old wooden trolley to put the cosmic ray detectors and projector on for the digital video work The Breath of Stars. This feels in keeping with the original furniture used at Hartland Magnetic Observatory. The Breath of Stars directly interacts with cosmic rays – as each cosmic ray particle strikes a plastic scintillator its energy is recorded and a starburst image video is projected. The interaction of cosmic rays and the solar wind with atmospheric electrical fields combines to influence the unpredictability of the magnetosphere. Most radioactive particles heading for Earth are deflected by the magnetosphere. Without the Earth’s magnetic field deflecting the majority of cosmic rays, life on this planet could not survive.

The 48 paper tiles for the roof of The Absolute Hut (of action potential) are made using the suminagashi technique of marbling with a colour to reflect both the sky and the patinated copper roof tiles of the Observation Hut at Hartland Magnetic Observatory. The paper is Japanese Osho Select and is very fragile when wet so has to be pulled from the water tray using a supporting mesh. Topological contours of suminagashi marbling reflect the fluid motion of the Earth’s magnetic dynamo and the pulsating alpha waves of the human brain when subjected to magnetic fields.

If you place a polarising filter over a screen that emits polarised light and use a polarising lens on the camera, then any plastic, photographed in this method, especially injection-moulded plastic, reveals stress points with a kaleidoscope of colours known as birefringence. Cryptochrome, the protein molecule found in a birds eye that enables birds to ‘see’ the magnetic field is excited by polarised light. Polarisation may also reveal the existence and properties of magnetic fields in the space medium light has travelled through. Research suggests that human alpha brainwaves react to a changing magnetic field. These ideas are brought together in a video work speculating on human magnetoreception via magnetite crystals in brain cells.

This video work will be shown on multiple small screens inside The Absolute Hut (of action potential) alongside two larger monitors showing companion video pieces exploring dynamics between the Earth’s geologic structure and navigation using the magnetic field.

I have replicated the experiment I saw at the National Physical Laboratory, dropping a magnet down a copper pipe to see how the magnetic field generated slows the magnet down considerably. I filmed this and added a tiny led light with the magnet.

Finally dark skies and fine weather coincided so I was able to go and make a time lapse of the stars rotating around Polaris.

Instruments of the Anemoi is a set of three dodecagon tablets cast in Snowcrete, a non-magnetic cement, as used in a magnetic observatory. Suggestive of the pedestals that support various instruments used in monitoring the Earths’ magnetic field they also respond to an ancient anemoscope “table of the winds” inscribed with the Greek and Latin names of classical winds on each of its twelve sides.

Hand cut copper pieces to be etched with images based on associations and attributes of the twelve Greek wind gods.

Sugar lift solution is screen printed onto the copper pieces.

These are then dipped in bitumen and immersed in hot water where the sugar slowly dissolves to reveal the image.

They are then left to dry before being etched.

These were etched for 2 hours in an Edinburgh Etch solution, made with ferric chloride, citric acid and water to get a deep etch. The detail in the bitumen held very well. I constructed a collagraph from card to attach them to for casting in concrete. Once etched the detail areas were painted with a soy sauce solution before being placed in an ammonia vapour bath.

After a few hours patinating they are removed to dry before being cleaned up.

Positions are marked out on the collagraph and double sided tape is used to secure the pieces in place face down. The collagraph is then placed in the silicon mould ready for casting with Snowcrete – the same non-magnetic concrete used at a magnetic observatory.

This is the third of the tablets to be cast for the work Instruments of the Anemoi. The first holds a copper bowl with a ‘silver fish’ floating in water based on the oval shaped compass needle (illustrated in Breve Compendio de la Sphera de la arte Navegar by Martin Cortes 1551) as symbol of the silver fish – wafer thin fish shaped iron leaves used by 11th century Chinese geomancers.

The second has embedded magnets in a pattern revealed by old nails and iron filings over the surface. One legend on the discovery of the lodestone recalls a Greek shepherd who noticed the nails in his boots were attracted to the lodestone (also known as magnetite a naturally occurring mineral).

The tablets will be shown on adapted wooden theodolite or telescope tripods in the spirit of equipment seen below during my research trip to Hartland Magnetic Observatory.

Seismic Mother curated by Charly Blackburn and Holly Birtles at Hypha Space – an exhibition of 20 artists whose work attempts to communicate the seemingly incomprehensible nature of the earth’s magnitude and magnificence, temerity and resilience as it endures, regenerates and struggles to survive through the slow violence of ecological catastrophe. I visited for the book launch and performative reading from Stephen Cornford whose book, Petrified Matter, I bought. It’s an enlightening read on the links between photography and fossils through mineral, chemical and data recording processes, going on to speculate on future geology and the impossibility of reversing the extraction process by separating minerals used in mobile phones and other technology to return these back to the soil.

Over the centuries many wind roses have been designed with varying numbers of wind directions from four to thirty-two cardinal points. The contemporary compass rose has its roots in the ancient classification of the winds.

Working on the sculpture series of tablets titled Instruments of the Anemoi after the gods of the winds. Twelve sided non-magnetic concrete tablets suggestive of the plinths that support various instruments used in monitoring the Earths’ magnetic field and the ancient anemoscope “table of the winds” carved in marble around eighteen hundred years ago and inscribed with the Greek and Latin names of classical winds on each of its twelve sides.

Testing an inked collagraph for concrete casting.

The first tablet in the series is cast with a collagraph which takes the commonly used oval shaped compass needle (illustrated in Breve Compendio de la Sphera de la arte Navegar by Martin Cortes 1551) as symbol of the silver fish – wafer thin fish shaped iron leaves used by 11th century Chinese geomancers.

The weather made the casting process a little precarious with the heat drying the concrete faster than ideal. The result has some fine cracks but overall I am pleased with the result. I used a convex glass lens to create a dip for a copper bowl to sit in. The glass had to be dremelled out after unmoulding. It left a very shiny surface. I made the copper bowl by hand at the London Sculpture Workshop. The ‘silver fish’ is cut from a silver gilding sheet.

The next tablet I am working on will contain embedded magnets. An elaborate frame is in construction to suspend the magnets in the concrete while it sets.

I will also add crushed shells as aggregate, so more pounding shells in the garden is necessary.

Continuing work on The Absolute Hut (of action potential). The Absolute Hut is structurally conceived from an amalgamation of features, impressions and functions of the Observing Building and instruments at Hartland Magnetic Observatory in North Devon and the observation huts built in the 18th century at The Kings Observatory in Kew for meteorological and magnetic observations.

Cutting old featherboard planks to length and hammering them to the frame of the north facing wall with copper nails. These panel sections are now left facing north to gather some moss before the exhibition.

Exciting copper patination tests for the pyramidion to sit on top of The Azimuth Obelisk (of sedimentary knowledge) sculpture. The sculpture expresses the passage of time; made from recycled paper prints and drawings whose history is embedded in the stacked layers, much as the Earth’s geological and magnetic history is secreted into sedimentary strata of rock.

The copper is cleaned first with whiting and ammonia solution. For the test strips I used parcel tape, water based and spirit based varnish, salt and vinegar solution, soy sauce and seaweed plant food. These are applied to the copper which is then placed suspended in a sealed container with a little ammonia. Effects are immediate but I left this overnight.

The next day they are taken from the tank and left to dry.

Both types of varnish interacted with the ammonia fumes, either going dark or puckering and crazing. The parcel tape left a clear band of copper when removed. The salt and vinegar mix gave a light blue patination and the soy sauce and plant food varying greens as copper where it was left raw. The colours continue to develop.

Preparing and patinating the copper triangles I had laser cut to size for the pyramidion. Applying strips of parcel tape to match up at the corners. Setting up a cat defence for drying the plates outside.

Once dry the colours continue to develop. I wanted to spray the surface with Golden archival acrylic spray but it was out of stock everywhere so I got Lascaux archival varnish with UV protection and gave it four light coats. It still continues to change though and flake off a bit adding to the effect of geological, topographical transformation.

I used Sugru, mouldable glue, building it up in stages to fix the sides while the pyramidion is supported in a frame.

Making use of the communal lounge at Thames-side Studios to test some paper template layouts for Domain of the Devil Valley Master. A sculpture using directional magnetic steel laid in a simple spiral which draws upon many references, from the shape of our own Milky Way Galaxy sculpted by vast cosmological magnetic fields, the spiralling molten dynamo generating Earth’s magnetic field, to the inner pathway of spiritual growth and the route to the symbolic omphalos (navel) at the centre of the world where the sky entrance and the underworld meet.

As research for new video work I am looking at experiments performed by Caltech geobiologist Joseph Kirschvink and colleagues investigating human magnetoreception. They found evidence that rotations of Earth-strength magnetic fields produce strong, specific and repeatable effects on human brainwave activity in the alpha-wave band. Alpha waves are always present, but are more prominent when at rest. The experiment, carried out at Caltech, mimicked how a person might experience the Earth’s magnetic field when turning their head. Although many migrating and homing animals are sensitive to Earth’s magnetic field, most humans are not consciously aware of the geomagnetic stimuli that we encounter in everyday life. Either we have lost a shared, ancestral magnetosensory system, or the system lacks a conscious component with detectable neural activity but no apparent perceptual awareness by us.

Friends from the north visiting London, told me about Haverah Park which is just up the road from where they live in North Yorkshire. The Haverah Park experiment was a cosmic ray air shower detection array consisting of water Cherenkov detectors distributed over an area of 12 km2 . The experiment began in 1967 and was operated by University of Leeds for 20 years before closing. During its operation, many thousands of cosmic ray events were recorded including four exceptional events with energies over 1020 eV. The abandoned huts remain and I am very excited about visiting the site to investigate further.

Anselm Kiefer Finnegans Wake at White Cube Bermondsey – “the artist’s new paintings, sculptures and installations respond to (that is, struggle with and transform) James Joyce’s novel of 1939. Kiefer first read the Irish writer as a young man, devouring Ulysses (1922) and embarking on a slow and spiralling relationship with the later, more exacting, Finnegans Wake. It is a book of circles and echoes, more or less overt or secret; its riverine movement begins in the midst of things, and turns back on itself on the final page.”

The weight and the scale of his work as always is overwhelming.

In my early research wondering what the building blocks of the universe looked like I found myself reading about Quarks and Leptons. I found the language of particle physics to be quite like that of mythology – inhabited with mysterious characters like the charm quark and strange quark, the muon and the tau governed by fundamental forces that cannot be seen or explained other than by their attributes – like the mythical gods. The name “quarks“ was chosen for the three fundamental particles of all matter from a nonsense word used by James Joyce in the novel Finnegan’s Wake:

“Three quarks for Muster Mark!“

Finnegans Wake seeks to inhabit a commonplace but elusive realm of human experience – the language is more like poetry than prose and should be read intuitively – the first sentence of Finnegans Wake completes the end of the last sentence – the book’s circular structure embodies the theories of the 18th Century philosopher Giambattista Vico, who viewed human history as cyclical along with the natural cycles of the earth such as night and day, life and death, rise and fall. Vico believed that there was a poetic wisdom in legends which gave an insight  into the relationship between the divine, the natural and the human worlds. He was interested in how myths began from common primordial experiences of the forces of nature.

A different kind of immersion – made from light rather than lead. Sarah Sze The Waiting Room at Peckham Rye Station, an Artangel project, is a captivating spectacle of colour and movement. It might be a lesson in attention spans and ubiquitous digital media but it still holds all the joy of being at the centre of a rotating fairground carousel.

“I’ve always been interested in certain times throughout history where our relationship to the way we experience time and space in the world speeds up radically. The invention of the aeroplane, the invention of the train, you see really interesting work coming out of that time, in film, visual arts and writing. We are in the middle of an extreme hurricane where we are learning to speak through images at an exponential pace.” Sarah Sze

Dear Earth at The Hayward Gallery is inspired by artist Otobong Nkanga’s suggestion that ‘caring is a form of resistance’. Bringing together 15 artists from around the world, the exhibition explores the interdependence of ecologies and ecosystems, as well as our emotional connection with nature.  

Day trip to West Wycombe Park; “one of the most theatrical and Italianate mid-18th century buildings in England” surrounded by “the most idiosyncratic 18th century gardens surviving in England”. Sir Francis Dashwood built West Wycombe to entertain, and there has been much speculation on the kind of entertainment he provided for his guests at the house and the nearby hellfire caves.

A surprise discovery in the gardens was The Temple of the Winds, a stucco and flint faced octagonal tower, aligned with its main walls facing north, south, east and west. Erected in 1759 and used as an ice house, its design was inspired by the ancient Tower of the Winds in the Roman Agora in Athens of which Vitruvius wrote

Some have chosen to reckon only four winds; the East, blowing from the equinoctial sunrise; the South, from the noon-day sun; the West; from the equinoctial sun-setting; and the North, from the Polar stars. But those who are more exact, have reckoned eight winds, particularly Andronicus Cyrrhestes, who on this system erected an octagon marble tower at Athens, and on every side of the octagon, he wrought a figure in relieve, representing the wind which blows against that side: the top of this tower he finished with a conical marble, on which he placed a brazen Triton, holding a wand in his right hand; this Triton is so contrived that he turns round with the wind and always stops when he directly faces it; pointing with his wand over the figure of the wind at that time blowing.

Reading

Ursula Le Guin The Winds Twelve Quarters (volume ii) – a collection of short stories, chosen for the title’s relevance to the sculpture series – Instruments of the Anemoi (wind gods).

The story The Stars Below is particularly interesting, written to interrogate the question – what happens to the creative mind when it is driven underground? Le Guin found that ‘you don’t go exploring the places underground all that easily’ as simple symbols took on unexpected divergent meanings and rather than the repression of science or art it was the abyss of the psyche she was fathoming. Le Guin later came across a passage in Jung likening the depths of ego-consciousness to ‘being surrounded by a multitude of little luminosities..[ ].. The star strewn heavens, stars reflected in dark water, nuggets of gold or golden sand scattered in black earth’

Really pleased with the results I am getting from the new batch of directional magnetic steel sent from Union Steel Products. These are coming out better than in previous tests.

Norman P. Goss invented grain-orientated steel in 1934. It was produced through a two-stage cold rolling process with intermediate annealing between the cold rolling stages. Grain-oriented electrical steel enabled the development of highly efficient electrical machines, especially transformers. Today, the magnetic cores of all high-voltage high-power transformers are made of grain-oriented electrical steel. The strong preferred crystallographic orientation is known as a Goss texture.

When I receive the electrical steel it has a grey insulation coating which has been applied to both sides of the sheet to avoid eddy currents between the stacked sheets when used in a transformer core. I am removing this coating by sanding. I then etch the sheets in copper sulphate solution for 20 minutes. The plate must be dried very quickly when it is taken out of the etching bath. I then lightly polish and wax the surface. Some detail is lost quite quickly and areas can become muddy after etching so I still need to experiment a little more with alternative cleaning and sealing methods.

A previous batch had a different coating that proved impossible to remove cleanly even with the most extreme methods. This new batch has two different types of sheet which have a slightly different pattern to reveal. It is quite hard work but a fascinating material to experiment with.

I have been considering using the Directional Magnetic Steel Pieces in some form of suspended sculpture as movement causes the surface to catch the light revealing the patterned surface of this material. I might use it to mark the line of declination across the gallery floor from True North to Magnetic North at the time of installation.

Thinking about moving sculptures –

Imagine holding Einstein’s attention for the forty minutes it takes your work to revolve. A Universe by Alexander Calder 1934, painted iron pipe, steel wire, motor, and wood with string. One of the first artists to explore kinetic and motor driven sculpture, expanding drawing into 3D and painting into motion. A nice intro to Calder from 2016 – The Universe of Alexander Calder with Dara Ó Briain.

Work continues on the Azimuth Obelisk with the construction of the metal frame to support the structure and hold the layered paper sheets. Thanks to Giles Corby of the London Sculpture Workshop for getting to grips with my diagrams and welding the frame. The frame is made in three interlocking parts to distribute the weight and make for easier storage and transportation. This sculpture is a response to the concrete obelisk erected in 1955 at Hartland Magnetic Observatory, near the site’s northern boundary as a permanent azimuth mark. It is viewed via a theodolite through a window in the north wall of the Absolute Hut, its azimuth being 11º27’54” E of N and marks the point from which the magnetic north pole is tracked as it drifts westwards.

The British Bryological Society celebrates its centenary this year, promoting the study of mosses and liverworts. I have been searching their website for clues on growing moss. Most of the information is on the identification of mosses but I did find a useful downloadable pdf of The Moss Growers Handbook by Michael Fletcher. No mention of liquidising moss with yoghurt as a starter culture though.

Gathering moss, liquidising with yoghurt and painting on to reclaimed old boards.

I made a rough model of The Absolute Hut to work out how many boards I will need for the north facing wall to try and grow moss on. I like that it turned out looking like a bird house as inside will be video exploring the magnetoreception of birds. This work is a reimagining of the Absolute Hut at Hartland Magnetic Observatory where monitoring of the Earth’s magnetic field takes place.

Some speculation on human magnetoreception:

Neurons send information electrochemically around the body. The signals they send are called action potentials which is a temporary shift from negative to positive within the cell caused by certain ions entering the cell. Research has proven that some animals can sense the magnetic field via cryptochrome molecules in the retina which trigger action potentials. New studies have been carried out looking at iron particles (Fe3O4) found in the brain using supersensitive magnetic sensors to read the brain’s magnetic field. Receptor cells containing crystals of magnetite could register changes in magnetic fields and report this information to the brain.  

One study suggests that it could be possible for the magnetic field in one animal’s brain to transmit information to another animal’s brain by triggering action potentials creating the same thoughts and emotions. There have been experiments with rats and fruit bats which claim brain to brain communication has occurred. Alpha waves in the human brain have been shown to respond to magnetic fields. Alpha waves are always present, but are more prominent when at rest. The experiment, carried out at Caltech, mimicked how a person might experience the Earth’s magnetic field when turning their head. 

Maybe putting our heads together can exchange thoughts telepathically.

I have taken the contour lines from a publicly available World Magnetic Model Field Map as a framework for layering in the video work on bird magnetoreception.

An early frosty morning captured the sun melting the ice on the lens of the spy cam in the garden.

I have built the protective box frame for the monitor that will be inside the mollusc/rock sculpture Belly of a Rock. Thanks to Pete next door for cutting the wood for me. I plan to build the shape up with mesh covered in paper clay. I have had the idea to make small circular paper clay clumps with swirls of crushed shell on each one and build the form up from these. I have been given a lot of oyster shells and have collected mussel shells which I have tested crushing with a pestle and mortar.

The drift of the magnetic North pole was first recorded in 1831 and historically would wander between 0–15 km a year but since the 1990’s it has sped up to drift 50–60 km a year. Tracking changes in the magnetic field can tell researchers how the iron in Earth’s core moves.

Earth’s magnetic field is created in the swirling outer core. Magnetism in the outer core is about fifty times stronger than it is on the rocky surface of the Earth. At the centre of the Earth is the inner core which is divided into eastern and western hemispheres. In the inner core, the temperature is so high, materials lose their permanent magnetic properties as the atoms are so thermally excited they can no longer align to a magnetic point. This is known as the Curie temperature.

The hemispheres of the inner core have distinct crystalline structures and the western hemisphere seems to be crystallizing rapidly whereas the eastern hemisphere may actually be melting.  Geoscientists have also recently discovered that the inner core has an inner core. A radical geologic change about 500 million years ago may have caused this inner inner core to develop. Here the crystals are oriented east-west instead of north-south and are not aligned with either Earth’s rotational axis or magnetic field. The inner inner core crystals may have a completely different structure to the hexagonal close-packed (HCP) phase of iron that is stable only at extremely high pressure and so may exist at a different phase.

ESA’s three-satellite Swarm mission was launched in 2013 to monitor Earth’s magnetic field by measuring magnetic signals from Earth’s core, the crust, oceans, ionosphere and magnetosphere. Using data from the Swarm mission, scientists have discovered energy generated by electrically-charged particles in the solar wind, which can be disruptive to communication systems, flows asymmetrically into Earth’s atmosphere towards the magnetic north pole more than towards the magnetic south pole. They have also discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. These magnetic waves are likely to be triggered by disturbances deep within the Earth’s fluid core. Research suggests that other such waves are likely to exist, probably with longer periods.

Geomagnetic jerks are sudden powerful waves that occur about every three to 12 years and are not consistent across the globe. It seems these jerks originate from rising blobs of molten matter that form in the planet’s core up to twenty five years before the related jerk takes place. The current findings from Swarm are part of a long-term project to predict the evolution of the geomagnetic field over the coming decades.

Polarised light is when the waves of electric and magnetic fields vibrate preferentially in certain directions. This can happen when light bounces off a reflective surface like a mirror or the sea. It can also happen in space as starlight travels through gas and dust clouds. Polarisation carries a wealth of information about what happened along a light ray’s path and astronomers can study the physical processes that caused the polarisation.

The Milky Way is filled with a mixture of gas and dust from which stars are born. Cosmic dust grains are almost always spinning rapidly, tens of millions of times per second, due to collisions with photons and rapidly moving atoms. The spinning dust grains become aligned to the direction of the magnetic field. They emit light at very long wavelengths from the infrared to the microwave domain which comes out vibrating parallel to the longest axis of the grain, making the light polarised.

Visualisation of data from ESA’s Planck satellite shows the interaction between interstellar dust in the Milky Way and the structure of our Galaxy’s magnetic field. Polarisation-sensitive detectors were able to capture the data as interstellar dust grains tend to align their longest axis at right angles to the direction of the magnetic field resulting in light emitted by clouds of gas and dust being partly ‘polarised’. Researchers are using the polarised light from interstellar dust to reconstruct the Galaxy’s magnetic field and study its role in galaxy evolution and star formation. From this data it can be seen that across the galactic plane there is a strong regular pattern but in some areas there are tangled features where the local magnetic field is particularly disorganised.

New images from NASA’s James Webb Space Telescope show star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths. NGC 1433 is a barred spiral galaxy with a particularly bright core surrounded by double star forming rings. For the first time, in Webb’s infrared images, scientists can see cavernous bubbles of gas where forming stars have released energy into their surrounding environment.

The Observable Universe 2018 by Pablo Carlos Budasi. The furthest we can see is the faint glow from the cosmic microwave background emitted 13.8 billion years ago.

From Earth we become the centre of the eye that gazes out but we have no idea of the full size of the universe or if we are embedded in a multiverse.

The unobservable universe makes up the vast majority, around 95% of the universe. Zero, a symbol to mark nothing, sits on the boundary between absence and presence indicating what might have been or might come to be. Where we thought there was nothing we have found so much.

Richard Mosse Broken Spectre at 180 The Strand. Seventy minutes of emotionally uncomfortable yet beautifully riveting viewing. Endless overwhelming destruction. Burnt forest. Subterranean fires. Intensive cattle farming. Aggressive gold mining. Wide wide screen images that slip between dreamlike garish colour and chilling monochrome with a soundtrack that sounds like the forest itself crying. The brutal disrespect for the land, the non-human and the people of the Amazon rainforest captured in heartbreaking detail as it slips through our fingers. Having been looking at moss recently the large photographic works at the entrance to the film come across very moss like and emphasises the micro and macro nature of the world.

Cable Depot presents Insert Coin, a project by Bob Bicknell-Knight exploring predatory monetisation practices within video games, specifically loot boxes, and the ongoing insertion of gambling mechanics into virtual experiences. Tapping into our desires and the addictive thrill of winning Bob Bicknell-Knight invites us across the digital divide into a luminous world of pixels and 3D printing. I was delighted to win an island. Here everything is free so there is no uncertainty and debt to mar the experience.

As our physical lives are becoming increasingly gamified the game industry has, for almost twenty years, been inserting ways of gambling real world money into video games. From purchasing extra lives to play another level in Candy Crush to buying new cosmetic options for your guns in Call of Duty, spending money within video games has become increasingly prevalent.

One of the most prevalent and destructive forms of monetization are loot boxes, consumable virtual items that are bought within video games which can be redeemed to receive a randomised selection of further virtual items, ranging from simple customization options for a player’s avatar or character to game-changing equipment such as weapons and armour. As the items are randomised players have previously spent thousands of pounds attempting to gain specific products in different games. As these gambling mechanics have become more prevalent, with considerable harm being done to young people and players with gambling addictions, loot boxes are now illegal in several countries, whereas recently the UK government decided that loot boxes will not be regulated under betting laws.

Julie F Hill Earth, Water, Night at The Stone Space

We so often look out at the night sky forgetting it is gazing back at us.

‘… The [pool] is the very eye of the landscape, the reflection in water the first view that the universe has of itself …’ —Gaston Bachelard,

Holding the poetic and alchemical in contrast to the objective and scientific, astronomical data of deep space folds into Earth’s deep time. Light and shadow gather in pools of water, forming images that suggest consciousness is a fundamental property of all matter.

Beautiful and contemplative works capturing the milkyness of the Milky Way caught in the folds of the night sky; distorted reflections rippling across dark pools; illusory depths oscillating between dimensions.

Sam Williams Deep in The Eye and The Belly (Part One) at San Mei Gallery. It was a busy night at the opening and I didn’t take any photos. There was a large projection on one wall and two other films showing on monitors with headphones. The work describes stories of cetacean bodies, interlacing actual historical events with speculative narratives. The camp narration of the main film deliberately jars with the emotive subject matter, but is given context through the supporting films as the protagonist who features across each film is seen reclining wearing feathers and glittery regalia speaking in long drawn and world weary sentences or lamenting the loss of the whale in absurd song from the vantage of a lighthouse.

Reverse Parking at Thames-side Gallery curated by Peter Lamb and Katie Pratt.

Reverse Parking presents seven artists (Gordon Cheung, Will Cruickshank, Cristallina Fischetti, Oona Grimes, Paul Hosking, Peter Lamb and Katie Pratt) whose work explores the duality of reality and the technological sublime. A bold and vibrant show. Good to see some large work from Oona Grimes and to chat with her in the gallery; her battle scenes encompassing battles down the ages coincidentally emerged at the onset of war in Ukraine. Also interesting to hear Katy Pratt discuss her language of abstract painting on the excellent Art Fictions podcast.

…not necessarily in the right order at Stephen Lawrence Gallery takes a playful cue from the Morecambe and Wise sketch with special guest Andre Previn which is embedded in British cultural history. Work from the featured artists (Carol Wyss, Dominic Murcott, Graeme Miller, Dirty Electronics and Dushume) overlaps and layers through still image, sound and projection. Exhibited is the third iteration of Carol Wyss’s giant etchings that expose the inner recesses of the human skull. Here they are made luminous and their sculpted landscapes all the more surreal by the animated light sequences traversing their surfaces.

Not observant enough to realise I bought the pocket guide version of The Natural Navigator by Tristan Gooley I ended up with an unembellished rather prosaic read with lots of facts and charts and possibly useful information that requires a large investment of dedication to the cause to learn many of these techniques. What was amusing though was finding the section headed Mosses and Lichens opens with the paragraph –

‘There is a commonly held belief that “Moss grows on the north side of trees and buildings.” It does, sometimes, but will also grow on every other side.

He goes on to say that moss doesn’t care about direction, but it does care about moisture. So in the northern hemisphere the side away from the sun is preferred by moss as it retains moisture for longer. Gradient is also important to prevent run off of water. I have tried to prop my planks at as low an angle as possible in the side passage but may need to find somewhere I can lie them down more.

I am enjoying dipping in to Florian Freistetter’s A History of the Universe in 100 Stars. No longer a swathe of uniform twinkling points of light but each star has its own character and story. It starts with 100 stories but we can extrapolate that to consider each of the many billion stars as individuals.

In Our Time – Superconductivity Excellent guest speakers (Nigel Hussey, Professor of Experimental Condensed Matter Physics at the University of Bristol; Suchitra Sebastian, Professor of Physics at the Cavendish Laboratory at the University of Cambridge; Stephen Blundell, Professor of Physics at the University of Oxford) on this podcast. Superconductivity was a surprising discovery in 1911 by the Dutch physicist Heike Kamerlingh Onnes who found that when he lowered the temperature of mercury close to absolute zero and ran an electrical current through it, there was no resistance to the current. Many other materials have also been found to share this property when cooled to a pivotal temperature when the material suddenly enters a different phase and behaves in a completely different way. As water moves from solid to liquid to gas at different temperatures so metals can move between solid, liquid and superconductor. Further research found that a superconductor also expels magnetic fields and this has been exploited in the making of MRI scanners and to speed particles through the Large Hadron Collider.

I also enjoyed hearing how, what were once impossible numbers, called imaginary numbers by Descartes, have turned out to be fundamental and integral to explaining oscillations and the sort of wave like structures in the universe that we encounter when diving into a quantum world.

The Curious cases of Rutherford and Fry – The impossible number

Editing footage for the video Belly of a Rock which will be shown on an old monitor encased in a sculptural hybrid form relating to both mollusc and rock. The giant sea slug of the mollusc family, can derive directional cues from the magnetic field of the earth which is then modified in response to the lunar cycle. It orients its body between north and east prior to a full moon. In the slug’s nervous system, four particular neurons are stimulated by changes in the applied magnetic field, and two are inhibited by such changes suggesting that the animal uses its magnetic sense continuously to help it travel in a straight line.

The Earth can be divided into the inner core, the outer core, the mantle, and the thin crust. The outer core is about 1,367 miles thick and mostly composed of liquid iron and nickel. It is very malleable and in a state of violent convection. The churning liquid metal of the outer core creates and sustains Earth’s magnetic field. At the boundary between the inner and outer core temperatures can reach 6,000° C which is as hot as the surface of the sun. The inner core is a dense ball of mostly iron, but with a temperature above the melting point of iron, it is not liquid or even molten. Intense pressure from the rest of the planet and its atmosphere prevents the iron inner core from melting as the iron atoms are unable to move into a liquid state. It could be described as a plasma behaving as a solid. The inner core rotates eastward, like the surface of the planet, but it’s a little faster, making an extra rotation about every 1,000 years.  Geoscientists think that the iron crystals in the inner core align north-south, along with Earth’s axis of rotation and magnetic field and are arranged in a hexagonal close-packed pattern. The orientation of the crystal structure means that seismic waves travel faster when going north-south than when going east-west. Seismic waves travel four seconds faster pole-to-pole than through the Equator. 

The Earth is still cooling and as it does so, bits of the liquid outer core solidify or crystallize causing the solid inner core to grow by about a millimetre every year. The growth is not uniform, it is influenced by activity in the mantle and is more concentrated around regions where tectonic plates are slipping from the lithosphere into the mantle, drawing heat from the core and cooling the surrounding area. The crystallization process is very slow, and further slowed by the constant radioactive decay of Earth’s interior. Scientists estimate it would take about 91 billion years for the core to completely solidify but the sun will burn out in just 5 billion years. 

I have nervously passed the cosmic ray detectors over to programmer Jamie. It was hard to let them out of my sight after so much work to get them built but he can’t test the code he has written without them. The Breath of Stars directly interacts with cosmic rays in real time to trigger a digital reaction via a mini computer attached to a block of plastic scintillator and a sensitive photomultiplier. As each particle strikes the plastic scintillator its energy is recorded and a starburst image video relative to the energy released is projected, with the largest images representing the particles with the highest energy.

I am constructing an Obelisk sculpture in response to the concrete obelisk erected in 1955 at Hartland Magnetic Observatory, near the site’s northern boundary as a permanent azimuth mark. It is viewed via a theodolite through a window in the north wall of the Absolute Hut, its azimuth being 11º27’54” E of N and marks the point from which the magnetic north pole is tracked as it drifts westwards. Layers of torn recycled paper are stacked like sedimentary rock that holds clues to the Earth’s magnetic field reversals in its strata.

Copper contours of magnetic field lines have been lacquered to preserve the heat patina from plasma gun cutting. These shapes will be pinned to the north facing mossy wall of the Absolute Hut installation, a reimagining of the Absolute Hut at Hartland Magnetic Observatory. I will also employ a north facing window from which to observe the azimuth mark of the Obelisk sculpture.

A second research visit to RSPB Snettisham, this time to see the pink footed geese (which over winter on the mudflats here) leave their roost at dawn to fly to the fields to feed.

The walk from the car park to the viewing area is over 2km and takes about half an hour to walk. Setting out before first light the weather felt promising but just as I erected the camera tripod the rain came down hard and didn’t stop for the rest of the morning.

Made a second attempt the next morning leaving a little earlier and although it remained dry there was heavy fog over the sea. Not great for filming with my very basic kit but very atmospheric to experience as the geese emerged from the sea mists.

The noise they make is incredible, a constant chattering building to a crescendo of honking calls as they rise from the water and swarm across the sky in their hundreds. They come in waves but look like particles. At one point what sounded like a few gunshots fired out across the bay in the distant darkness. This sudden disturbance set off a slow deep rumble which drew closer accompanied by a low dark cloud growing heavily stronger building and rising as a huge tidal wave of geese rose simultaneously into the sky in panicked disarray. Extraordinary to witness.

Birds are able to “see” Earth’s magnetic field lines and use that information for navigation. Their compass ability comes from a quantum effect in radical pairs, formed photochemically in the eyes. This light sensitive magnetic compass used by birds is affected by the polarisation direction of light. Exposure to blue light excites an electron, which causes the formation of a radical-pair whose electrons are quantum entangled, enabling the precision needed for magnetoreception.

In chemistry a radical is an unpaired electron which is can be highly chemically reactive. In the radical pair mechanism a pair of electrons with opposite spins have a chemical bond. Light can cause the electrons to change spin direction which can break the bond giving the electron a chance to react with other molecules. In magnetoreception two cryptochrome molecules, found in the rod cells in the eyes of birds, each with unpaired electrons, exist in states either with their spin axes in the same direction, or in opposite directions, oscillating rapidly between the two states. That oscillation is extremely sensitive and can detect the weak magnetic field of the Earth. Birds then move their heads to read the spin of the molecules and therefore detect the orientation of the magnetic field.

While in North Norfolk staying in a beach chalet away from light pollution I was able to make a couple of short time lapse videos centering on Polaris.

Birds can detect the slow arc of the sun and the rotation of the constellations across the sky which is imperceptible to humans and allows migrating birds to orient themselves using celestial navigation as well as magnetoreception.

Birds are also able to detect rapid movement such as individual flashes or flickering of a fluorescent light which humans see as a continuous light. Hawks which pursue other birds through dense forests at high speeds, follow the movement of their prey while avoiding branches and other obstacles. To humans travelling at this speed, the fleeing prey, branches and obstacles would just be a blur.

Thames-side Gallery ‘The Accurate Perception Available When Our Eye Becomes Single’ is an immersive multi-screen installation evoking the emotional specifics of place (Orford Ness on the Suffolk coast) while exploring the elasticity of time and history. It is an audio-visual collaboration between Richard Ducker (video) and Ian Thompson (sound) with no linear narrative; sound and image are not synchronised, so each viewing is a unique experience. Sarah Sparkes also makes an enigmatic performative appearance both in the video and live in the gallery.

The crashing sea on shingle, open spaces and brutalist bunker architecture of Orford Ness are echoed in the gallery with audio pitched to envelop and resonate but not overwhelm. Nicely done.

I really enjoy the Inside Science podcasts with Gaia Vince and this one interviewing cosmologist and theoretical physicist Laura Mersini-Houghton about finding evidence that supports her multiverse theory was particularly fascinating.

Merlin Sheldrake’s Entangled Life. A remarkable reveal of an other world, so different yet so entwined with our own. Beautifully clear analogies help to bridge an understanding between human and fungi.

The ability to detect and respond to chemicals is a primordial sensory ability.

In humans when a molecule lands on our olfactory epithelium and binds to a receptor it causes nerves to fire triggering thoughts and emotional responses.

A mycelial network is one large chemically sensitive membrane: a molecule can bind to a receptor anywhere on its surface and trigger a signalling cascade that alters fungal behaviour.

Fungal lives are lived in a flood of sensory information.

They have light receptors, are sensitive to touch and it also looks like fungi may form fantastically complex networks of electrically excitable cells – a potential ‘fungal computer’ using electrical signalling as a basis for rapid communication and decision making which could learn and remember.

Delighted to have my video installation At a Distance included in The Anxiety of Interdisciplinarity  exhibition in the subterranean labyrinth of former police cells that is The Island Venue in Bristol. Curated by Sarah Strachan and Ayeshah Zolghadr. Exhibition Images by Steve Russell Studios.

This is a satellite exhibition of the International Printmaking Conference taking place at The Centre for Print Research, University of the West of England, Bristol. Motivated by the International Multidisciplinary Printmaking Conference IMPACT 12’s theme ‘Merging and Metamorphosis’, the exhibition aims to trace the metamorphosis of conversations between disciplines, seeking to reframe printmaking practice as a ‘site of interdisciplinarity’ and consider contemporary approaches to print as ‘a site of ambivalence, tension or a fertile ground for exploration and experimentation.’

At a Distance looks at remote methods of communication and relates this to the mysterious twinning of electrons in quantum entanglement where particles link in a way that they instantly affect each other, even over vast expanses. Einstein famously called this phenomenon ‘spooky action at a distance’. Filmed on 29th March 2019 in Cornwall as the iconic Lizard Lighthouse powers up its lamp, solitary figures using semaphore flags sign ‘We Are One’ out across the ocean in the hope the message will be echoed back. Drawing on the physical language of print that embodies touch, separation and mirroring the flags have been printed using hand painted dye sublimation inks applied via a heat press. This process transfers the ink from a paper matrix onto the substrate textile. The image passes momentarily across space in a dematerialized state as vapour before being reformed as its mirror opposite.

Research visit to Hartland Magnetic Observatory. I am very grateful to The British Geological Survey for allowing me access to the site and particularly to Tom who shared his knowledge and gave a fascinating tour of the observatory. He was a little perplexed by my request to see the obelisk with the azimuth mark determined by observations of Polaris as he thought this description was a slight exaggeration of what was actually present. The ‘obelisk’ is almost hidden in thick undergrowth and impenetrable woodland so this object, just glimpsed amongst the trees remains an enigma.

Hartland was established in 1955 and is part of a network of international observatories sharing information with governments and industry, the charts of the shifting magnetic field are also publicly available. The buildings are made of lime bricks and timber, with concrete flooring and roofing of copper.

The Earth’s magnetic field acts as a shield against potentially harmful charged particles from outer space. It is also holds clues to the planet’s deep interior and geological history which are inaccessible to direct observations.

Magnetic declination is the angular difference between magnetic north and geographical or true north for any point on the earth’s surface. The British astronomer Sir Edmund Halley was interested in the magnetic field and knew about declination based on the observations of sea captains and explorers in various parts of the world. He made two scientific voyages in the Atlantic Ocean as captain of the HMS Paramore between 1698 and 1700 when he charted declination in the Atlantic and from his observations published the first geomagnetic field map in 1701. His observations involved recording the position of celestial objects and the angular distance of the sun on the horizon.

I am intrigued to know what the middle species he encountered between a bird and a fish might be. Penguins with long swan necks?

Alexander von Humboldt determined that the magnetic field increased in intensity with distance from the equator based on magnetic field observations during his scientific journeys 250 years ago. He initiated coordinated observations across the globe and thus laid the foundation for international data exchange and collaboration.

Observation is essential to gain insight into the complexities of the geomagnetic field which is created by a combination of three separate fields. The main field is generated in the earth’s core, the second from electrical currents caused by solar weather as cosmic particles bounce off the Earth’s main field charging the surrounding ionosphere and thirdly from the magnetisation of the surrounding geology of the rocky mantle and crust.

The purpose of a magnetic observatory is to measure the size, direction and changes to the natural magnetic field at the surface of the earth. There is no clear separation between north and south currents at the equator as many diagrams suggest, everything just gets a bit muddled with tangled currents.

The fluctuations in the geomagnetic component fields occur over hugely different timescales, changing by the second as we orbit the sun, to the yearly drifting of magnetic poles and the millennia of deep geological time. To study these changes an observatory must make measurements at exactly the same point over a long period of time.

Activity in the ionosphere causes a compass needle to shift slightly throughout the day but these changes, although rapid, are very small, so the instruments measuring these fluctuations must be very sensitive and operate in an environment free from man made magnetic contamination which is why I was advised to park some way from the observatory.

Rapid changes in the geomagnetic field due to magnetic storms can impact navigation data which is particularly important for the oil industry that uses this data for accurate drilling references. Data monitoring solar variability can also help studies into the mechanisms of climate change. It has been noticed that the Sun’s coronal magnetic field has doubled over the last century and this may have an effect on cloud formation which has an impact on warming the planet.

Today at Hartland, the intensity and direction of the magnetic field is sampled using one manual and two automated instruments. A fluxgate magnetometer (variometer) is used to measure variations in the direction of the field every second. It has copper coils and three orthogonal sensors (measuring north, east and vertical). This instrument is extremely sensitive, mounted on a marble block on a pillar set into the bedrock to avoid tilting, it must be kept at a constant 23C temperature. It is housed in a special building with thermally insulated inner chambers within inner chambers, isolated in the dark, it is only visited once a year. We didn’t even walk too close to the building which appeared to have no door.

The second automated instrument is a proton precession magnetometer to measure the strength of the field. This also has its own building and new equipment is being tested here. As new instruments are introduced previously unseen minute fluctuations are revealed.

The manual instrument is a fluxgate theodolite housed in the Absolute Hut looking out of the North facing window. It sits on a lime brick and concrete pillar. This instrument has a magnetic sensor mounted on the non-magnetic telescope of the theodolite to detect when it is perpendicular to the magnetic field vector. True north is determined by reference to a fixed mark of known azimuth. This was the obelisk though today it is determined by GPS.

Absolute and variable measurements are combined to give a full record of the field.

It used to be that all the measurements were made by hand and this took time and skill to produce accurate results. The beautiful old instruments used still sit in the buildings at Hartland.

The Dye Coil measured the strength of the field in the vertical direction, using a coil that vibrates in the presence of a magnetic field as the sensing element. The Schuster-Smith magnetometer measured the strength of the field in the horizontal direction, using a magnet, a mirror and a light source to make a sensitive detector. The decinometer measured the angle between true and magnetic north using a freely suspended magnet and a theodolite to measure the angles. Three Danish LaCour variometers were kept in the recording house, each measuring the strength of the field, one for the north-south component, another for east-west and one for the vertical component of the field. All three used magnets attached to mirrors, which were free to rotate in the Earth’s magnetic field. A thin beam of light shone onto each mirror was reflected back onto a rotating drum covered in photographic paper. The drum driven by clockwork rotated once a day.

There are also three satellites which monitor the magnetic field from space (though these may only have about three more years of useful life). ESA’s ‘Swarm’ mission is dedicated to the study of the mysteries of the magnetic field which although invisible, together with electric currents in and around Earth, generates complex forces that have immeasurable impact on everyday life. 

Using measurements from ESA’s Earth Explorer Swarm mission, scientists have developed a new tool that links the strength and direction of the magnetic field to the flight paths of migrating birds. This new research means that the study of animal movement can now combine tracking data with geophysical information and lead to new insights on migration behaviour.

Hartland Observatory is situated on the dramatic North Devon Coast with stunning local geology. When the Earth formed about 4.5 billion years ago from the collision, accretion and compression of matter it was rock all the way through. Heat from the massive violence of formation along with radioactive decay caused Earth to get hotter and hotter. After about 500 million years as a rocky lump it reached the melting point of iron. Known as the iron catastrophe this liquifying caused planetary differentiation to occur as lighter material rose to the surface becoming the mantle and crust while heavy metals sank to the core becoming the churning dynamo powering the magnetic field.

During my visit the weather was kind and so I was able to fly my drone around the cliffs and rocky bays. I am still terrified of disaster every time I take it out, compounded by almost getting caught out by the incoming tide but I did get some useful footage for my ‘Belly of a Rock’ video sculpture I am working on.

When night falls after a warm day at certain times of year bioluminescence can be experienced at high tide in Hartland Quay. A young woman, and her mother (who swims across the bay at night here regularly) invited us into the pitch darkness to see the green sparks fly as we splashed in the rising water. It was incredible to witness. Swimming in the water limbs are coated in a luminescent glow. I tried to film the flashes on my phone and thought I had been unsuccessful as what I captured appeared totally dark. However, back at home I tried pulling out what information there was on each frame and managed to get a film sequence that might not show exactly what I saw but has an essence of the experience.

Visit to The King’s Observatory built by George III for the purpose of observing the transit of Venus across the sun in 1769. This observation allowed measurement of the distance from Earth to the sun, later named as the astronomical unit at around 150 million kilometres (8.3 light minutes).

It is now a family home and so the decor although representative of Georgian taste does not reflect the working laboratory that it once was.

Fascinating to discover it was also the site of the meridian line marked true north-south by two obelisks either side of the west room which housed a tracking telescope. There is a third obelisk due south from the east room which housed a mural quadrant used to measure angles. It wasn’t possible to walk over to the obelisks as the Observatory is in the middle of a golf course now, but there is a path to them via the Old Deer Park which I will walk another day. An accurate clock here provided standard time to the government before the task was transferred to Greenwich Observatory.

In 1842 it was renamed Kew Observatory and taken over by The British Association for the Advancement of Science. The Meteorological Office was based here, making regular records of the weather from 1773 until 1980. It was also home to the National Physical Laboratory between 1900 and 1914 when scientific instruments were checked for accuracy and stamped with KO, a hallmark of excellence if they passed.

The two huts remaining in the grounds were used for meteorological and magnetic observations and are built with no nails which might interfere with the instruments used within.

Francis Ronalds, director at Kew Observatory from 1842, invented several camera designs subsequently used in both weather forecasting and in understanding the perennial perturbations in terrestrial magnetism. Photography was used early on in its development for use in scientific investigations. Ronalds’ first instrument captured observations from his atmospheric electricity apparatus. He went on to record atmospheric pressure and temperature using the same method and had soon extended his approach to geomagnetism. His magnetographs “established the standard technique employed for magnetic observatory recording worldwide for more than a century” – Encyclopedia of Geomagnetism and Paleomagnetism.

In 1908 the geomagnetic instruments were relocated to the magnetic observatory established at Eskdalemuir in Scotland to undertake magnetic work for which Kew was no longer suitable after the advent of electrification in London led to interference with their operations.

Ronalds had also established an atmospheric electricity observing system at Kew with a long copper rod protruding through the cupola dome of the observatory connected to electrometers and electrographs to manually record the data.

Lord Kelvin later installed an updated electrical observation system and CTR Wilson (the inventor of the cloud chamber) set up a secondary system using different principles which has been useful in historical air pollution research.

I am extremely grateful to Professor of Chemistry at the University of Oxford Peter Hore for spending time chatting on zoom with me about his fascinating research into the ability of birds to navigate using the Earth’s magnetic field.  There is a link to a YouTube lecture by Peter on Radical pair mechanism of magnetoreception here.

Research confirms there is a chemical reaction in the bird’s eye sensitive to magnetic fields as weak as that of the Earth. This happens in an array of reactant molecules which can be changed into extremely short lived radical pairs which are magnetically sensitive. The reaction in the molecules to produce radical pairs is triggered by light from the sun or stars. It is thought that this chemical compass is sensitive to direction not intensity of the field and may use the energy from blue/green photons to power this reaction. During this reaction, as the bird changes direction, some radical pairs perform one way and others another creating difference across the array of molecules which is detected by the bird.

My question to Peter was to ask for his thoughts on whether a bird’s ability to ‘see’ the magnetic field manifests itself visually and if he has any understanding of what the bird experiences. He had to confess that how this sense is experienced by birds is not known but he had done some speculative modelling with a PhD student representing the field as fluctuating visual contour lines mapped over the landscape.

The birds eye is very complex and so there is still a lot to be learned about how this ability functions. Bird’s retinas have rods that are sensitive to light intensity and cones sensitive to red, blue and green wavelengths of light like us but they are also sensitive to ultra violet light. There are also double cones in the bird’s eye and their function is not clear, it could be that these are seconded for magnetic reception at night when they are not active.

Often birds fly high above the clouds when migrating and starlight appears to be enough to trigger the reaction in the molecules. In normal sight chemical messages are sent from the retina to visual processing centres within the central nervous system via ganglion cells. There are many of these ganglion cells in the birds eye and it may be they send the information bypassing any rods or cones. Studies on the retina show a reaction to the magnetic field when blue light is present but the activity has not been traced from the retina to a specific part of the brain yet which might determine if this sensitivity does manifest itself visually.

It is very difficult to imagine a sense we do not have.

Learning the migratory route and destination is vital to birds survival in many cases. Often the young bird will have to undertake the first migratory journey on its own, its parents having left earlier. These instinctive instructions for the journey are passed on from one generation to the next. The genetic instructions are quite broad, leading to a large designated destination zone which could be within a 200 mile radius. However, when returning, along with the hereditary instinct using the stars and sun to navigate the birds also have learnt the magnetic map and can return to the exact spot they left as a fledgling. Young birds in a planetarium will follow the stars if they are rotating correctly.

Peter is a chemist so his interest is in the chemical reactions of the radical pairs but he is part of a wider research group that also looks at this behaviour in bats and fish.

I also asked his thoughts on the human capacity to sense the magnetic field. Unfortunately, although we have cryptochromes in many of our cells we do not have the particular molecule Riboflavin which is the one activated by blue light to become magnetically sensitive. Whether we once had this molecule and lost it or birds evolved this molecule separate to our evolution is not understood but he did believe current research on human brain alpha wave activity in response to the magnetic field might throw up some interesting ideas to look at. A speculative approach to gaining sensitivity to the magnetic field may be by transplanting a tiny compass as used in a mobile phone onto the body, setting it to vibrate when pointing north. The body may ‘learn’ to recognise north in this way.

Listening to The Life Scientific with guest David Eagleman has shed further light on what might be possible as his research shows the human brain can be trained to receive input from alternative sources, for example learning to hear through the skin. He believes it will be perfectly possible for us to experience new senses in the future, including magnetoreception.

Work in Progress

I have been scouring the internet for tips on casting a concrete obelisk and getting an idea of the dimensions. I am thinking about using aerated concrete, for lightness but also to give an appearance of the texture of volcanic rock.

Chemical conversation tests for the video sculpture Belly of a Rock inspired by Italo Calvino The Spiral in The Complete Cosmicomics. “The water was a source of information, reliable and precise [ ] full of substances and sensations and stimuli”

I have been testing paper clay recipes and shapes for the video sculpture Belly of a Rock which will be somewhere between a rock and a mollusc.

Out of Studio

Visit to Richard Saltoun Gallery to see Haptic Vision a retrospective of artists Jo Bruton and Rosa Lee working in the 1980’s and 90’s creating paintings that encourage the eye to wander across a richly textured surface of optical illusions. “The necessity of ‘making’, of being within that space as a primary concern, where the Subject is nearby and woven into the repetitions and patterns of everyday life.” – Jo Bruton, 2022

Eternally Yours at Somerset House reflects upon the hope and healing which can be found in the memories and stories that everyday objects hold in our lives. The repair becomes a shared experience expanding the idea of bonding to include the emotional connection.

I really liked the DIY sensors and data gathering device created by Superflux. Re-imagining technology as a useful tool for communities to gather and share information on the environment, monitor local air pollution and be active in creating a just and equitable society.

New River Folk is the outcome of an Engine House Residency by Laura Copsey and Philip Crewe at the new Quentin Blake Centre for Illustration about to be developed at New River Head, Clerkenwell. This site was part of an artificial watercourse opened in 1613 to supply water to London at first through overground wooden pipes. When more pressure was needed a six-sail windmill pumped water from the site. After storm damage to the windmill in 1720 horses were harnessed to turn the wheel and power the pump. The round base of the windmill remains, and is the oldest construction of its kind in central London. The artists drew on local history around the site, creating an archeology expanding on the lives of Mole Catcher William ‘Mollitrappe’ Smythe, Well-Keeper Black Mary Woolaston and Tankard-Bearer Joan Starkey. They also collaborated with the river itself to create 16mm film imagery and recordings.

I was fascinated by the crystals that had formed on the bricks in the old windmill. The salt crystal growing experiment I set up while planning an exhibition proposal is still sitting in my studio – if it is still growing it is doing so very slowly, the initial growth was surprisingly fast.

Reimagining Joya is an exhibition at Thames-side Gallery inspired by the experiences and artistic responses of a group of artists who have all participated in Joya: Art + Ecology / AiR residency. The curators, Olga Suchanova, Tere Chad and Barbara Slavikova, have selected a body of works which explore the way we inhabit, survey, feel, and relate to the natural landscape and its living creatures.

Cornelia Parker at Tate Britain. Simple materials, deconstructed and presented immaculately. I was in awe of the invisible framing of her linen squares and wire grids where the objects appear held against the glass as if by magic. Many works are born in violence, condense violence into form or render it impotent. These include Bullet Drawings using lead from bullets melted down and drawn into wire; shotgun sawn off by criminals sawn up by police; handgun used by criminals precipitated to rust by science engineers. Gentler work included the back of button cards appearing as coded messages or star charts – something I was very familiar with as a child growing up in a village drapers shop.

Forest: Wake this Ground at The Arnolfini, Bristol showing works by Rodrigo Arteaga, Mark Garry, Alma Heikkilä, Eva Jospin, Jumana Manna, Zakiya Mckenzie, David Nash, Maria Nepomuceno, John Newling, Rose Nguyen, Ben Rivers, Ai Weiwei, and Hildegard Westerkamp.

Rodrigo Arteaga burned drawing series Monocultures and Fallen Tree documenting the radical change in the forest floor and threatened indigenous species.

John Newling extracts of soil form his own garden reveals a surprising diversity of minerals in the many colours of the balls and cores. The Night Books burning forests, made from pulped textscoal dust and crushed charcoal worryingly notes that the work physically released carbon through the process of making. The vertical strata reminds me of the cliffs at Hartland Bay.

Ai Weiwei cast from the ancient and endangered Pequi Vinagreiro tree (found in the Bahian rainforest), reflect both the uprootedness of arboreal species and the displacement of people.

Ben Rivers film Look Then Below shot beneath the Mendip hills and ancient woodland in Somerset, imagines a dystopian but seductive future.

Eva Jospin Forêt Palatine, made from recycled cardboard, at once evokes folklore and decay. I liked the surface texture which in parts almost looked volcanic.

Paths of Resistance by Tracy Hill is a site-specific fabric installation in response to magnetic fields measured in the space at Arnolfini as part of the IMPACT 12 programme of events. The work explores the hidden energies that shape our experience of the world.

New work has been framed – these pieces consider the potential for the human eye to perceive the Earth’s magnetic field. Research shows birds have this capability activated by molecules in the retina of the eye when excited by blue light. The molecules produce radical pair electrons sensitive to the magnetic field and as these molecules are found within the photoreceptor cells it is possible birds may visualise the magnetic field lines to aid navigation. A similar molecule is also found in the human eye and I am speculating that this is a sense we may once have experienced and could tap into again. It is of course the brain that must receive a signal from the eye by which we see. Independently of the cryptochrome molecule, research monitoring alpha wave activity shows the human brain does appear to be sensitive to a magnetic field albeit unconsciously.

The Compass Eye Etching with chinagraph pencil, magnets, iron filings

Pole Receptor 2022 27 x 27 x 3 cm Etching, magnet and iron filings

Framework made a neat job of the frames enabling the magnets to be released to reset the iron filings if necessary. The Compass Eye doesn’t have glass and maybe that was a mistake but I prefer the thin frame.

Progress is being made on new work Breath of Stars. This will be a screen based work triggered by cosmic ray activity. Every time an event is registered by a photomultiplier attached to a 5cm square piece of plastic scintillator, a star burst video image will flash up on the screen. The size of the starburst will correspond to the energy of the particle that has just arrived from space. The starburst videos are made in Adobe After Effects using footage from my cloud chamber experiments.

I have got some help with coding from gaming programmer Jamie Howard so am not feeling so out of my depth in the python maze. One problem we may have though is the shortage of Raspberry Pi processors. It could be months before we are able to get one with a high enough spec to process the video layering. In the meantime I am testing ideas and creating video clips.

It was wonderful to see so many people visiting the first Open Studios at Thames-side since 2019 despite the rail strike difficulties that weekend. The Compass Eye was hanging in the Thames-side Gallery Studio Holders Showcase exhibition. Thank you to everyone who came to visit and found their way to my studio, it was great to discuss everything from Plato to Planck.

Super happy to have my video Cosmic Chiasmus: crossing the universe included in the May Fair Showreel screening at the very smart May Fair Theatre as part of Mayfair Art Weekend. The departure point for the curated selection was the word ‘PROCESS’, which was inspired by the video work by Wolf Vostell, Auto-Faber (1973). It was a great experience to see all the amazing nominated films and meet the selectors -Elisa Tosoni, Angel Leung and Eugene Macki and art weekend project manager Cheri Silver.

What a lovely write up in the Winchester School of Art Yearbook 2022 from one of the Fine Art students on the Images In The Making sessions that I ran.

I am delighted that my installation The Forms has been selected for exhibition in the splendid Wells Cathedral as part of Wells Art Contemporary 2022.

Twelve aluminium plates in the shape of pentagons that together make up the net of a dodecahedron have been deep etched with imagery taken from data visualisation of dark matter provided to me by KIPAC, Stanford University. The etching process used a screen printed sugar lift technique where the bite was allowed to penetrate completely through the plate leaving holes in some areas.

Excited to be selected for a satellite exhibition at the international print conference IMPACT12 to be installed at a former police station in Bristol. At a distance will be shown in The Anxiety of Interdisciplinarity, an exhibition which seeks to reframe printmaking as a site of interdisciplinarity – a testing ground for ‘The important work…done at the surfaces between adjacent disciplines’ (Carter, 1998).

Drawing on the physical language of print that embodies touch, separation and mirroring the semaphore flags in this work have been printed using hand painted dye sublimation inks applied via a heat press. This process transfers the ink from a paper matrix onto the substrate textile. The image passes momentarily across space in a dematerialized state as vapour before being reformed as its mirror opposite.

Billed as an immersive experience like no other Dreamachine offers a unique journey into the potential of your mind. Stimulated by strobe lighting playing rhythms on your eyelids and spatial sound fed directly into your ears, your mind creates its own images behind closed eyes. Inspired by a 1959 invention from artist–inventor Brion Gysin it has been reimagined by Collective Act, in collaboration with Turner Prize-winning artists Assemble, Grammy and Mercury nominated composer Jon Hopkins, and a team of leading technologists, scientists and philosophers.

It was pretty amazing. From a deep orange glow of swirling matter kaleidoscopic shapes emerge with geometric patterns that form and explode into vibrant pulsating honeycomb structures. Felt sure I was seeing some of my recent work in there. Swept away on a tide of colour with a big smile it was like a roller coaster ride through the forming of a technicolour universe. Wonderful.

Interesting to read that the frequency range of light emitted by Brion Gysin’s Dream Machine corresponds to alpha waves, electrical oscillations normally present in the human brain while relaxing. The pulsating light stimulates the optical nerve and alters the brain’s electrical oscillations. I have been looking at scientific research that explores a connection between the Earth’s magnetic field and human vision when stimulated by blue or polarised light depending on the orientation of the viewer. The human brain’s alpha waves can be seen to react to the local geomagnetic field. Some research correlates the nature of our dreams to magnetic field activity with calmer dreams resulting from high activity and more bizarre dreams when activity is low.

Going from Dreamachine to Libby Heaney’s quantum world of morphing fluid shapeshifting worlds The Evolution of Ent @Arebyte was a nice continuation of mind bending immersion.

Ent-er. Ent-anglements. Ent-ropy. Ent-wining. Ent- hralling. Ent-icing.

Looking at the potential futures created by quantum computing where the digital mode of binary gives way to superposition and quantum entanglement. Daniel Cavalcanti has provided a useful quantum glossary in the exhibition catalogue. Explaining superposition as like looking through a window and seeing outside and yourself reflected simultaneously, two configurations happening at the same time.

I was very excited to visit The World of Stonehenge at The British Museum to see the Nebra Sky Disc, having been introduced to the existence of this amazing object by archaeoastronomer Carolyn Kennett while on the Lizard Point Residency in 2019. Found by metal detectorists in Germany the gold used in this ancient map of the cosmos can be traced to Cornwall.

Carolyn explaining the history of this most ancient of cosmological objects.

The actual disc was much larger than I expected and almost translucently thin.

Six thousand years ago in the final 1,500 years of the stone age was the British Neolithic period. A time of stone axes for chopping. Woodlands cleared for farming. Stone held meaning. Offerings were made to spirits. Hundreds of stone and wooden circles were raised across the land. A cosmic inversion, connecting earth to sky. The first stones were brought to Stonehenge about 5000 years ago to create a burial ground which was transformed 500 years later into the symbolic site where the large sarsen stones were placed in alignment with the sun as it rises at midsummer solstice and sets in midwinter. Some astonishing objects in the exhibition, the power of the sun celebrated and reflected in gold.

I had high hopes for Our Time on Earth exhibition in the Barbican Curve – the aim was for technology to bring us closer to nature and highlight our place as one species among millions of others, striving to live together in a delicate balance. There was some enticing imagery and interesting ideas but as an experience it was tech overload, information overload all crammed into quite a tight space. Too much to take in and too removed from a lived time on Earth for me to engage and absorb anything meaningful.

Postwar Modern at the Barbican Gallery explores the art produced in Britain between 1945 and 1965 in the wake of a cataclysmic war. Including; Denis Williams Painting in Six Related Rhythms 1954; Eduardo Paolozzi Will Man Outgrow The Earth? collage form the series Bunk 1952/1971; the lovely Aphra Shemza’s grandfather Anwar Jalal Shemza painting fusing Western ideas of abstraction with Eastern influence and Gustav Metzger Liquid Crystal Environment  made using heat-sensitive liquid crystals that are placed between glass slides and inserted into projectors where they are are rotated to create movement within the liquid causing the crystals to change colour as they are heated and cooled.

I was fascinated to learn about the numbering system used by Cistercian Monks while visiting the impressive ruins of 12th century Cleeve Abbey in Somerset. A single cypher can represent numbers up to 9999.

The abbey church was destroyed by Henry VIII during the dissolution in 1536 but the cloister buildings, gatehouse, 15th century refectory and 13th century heraldic tiles survived destruction as they were being used as farm buildings at the time and it’s ancient tiled floor was protected from the elements by a cabbage field.

Lode – a way or path, a watercourse, a vein of metallic ore.

A lodestone is a naturally occurring magnet possibly created by a lightning strike. Early compasses were made of lodestone suspended on a cord.

Magnetite is a common mineral that has an attraction to a magnet but is not magnetic in itself.

The image shows magnetite, sold on eBay as a Lodestone though at £2 what did I expect.

Fluid activity hidden deep in the Earth’s interior can be visualised through plotting the magnetic field and its fluctuations.

The geomagnetic field, generated by the Earth’s molten core, varies through time; the magnetic poles migrate, go on excursions or reverse polarity. During these periods of flux the strength of the magnetic field changes and this phenomenon is recorded in archaeological artifacts, volcanic rocks, and sediments. The mineral deposits of stalactites store a paleomagnetic history of declination (the deviation of magnetic from geographic north).

Thinking about how magnetic pole reversals are stored in geology. I am modelling some paper clay rocks for future filming visualising the magnetic field using iron filings.

Early navigators using the compass around the 15th century became aware that geomagnetic north would roam position. In 1701 the first map charting the magnetic field declination was produced by British astronomer Edmund Halley.

In the 19th century the study of geomagnetism became one of many passions for explorer polymath Alexander von Humboldt who studied

“what keeps the innermost of the world together, how all is woven together”

and was the first to connect climate with interactions between atmosphere, oceans, land and plant ecology. From meticulous observations he noticed the Earth’s magnetic field intensity increases from the equator to the pole, and that it was also influenced by auroras and solar activity causing magnetic storms.

Magnetic observatories to monitor the Earth’s magnetic field were set up around the globe including one at Greenwich which had to relocate twice due to infrastructure interference (electric railways) and is now based in Devon with a permanent azimuth mark on a concrete obelisk viewed from the north window of the Absolute Hut. I wonder if it is possible to visit.

Magnetotactic bacteria align themselves with the Earth’s magnetic field to navigate using nanoparticles of magnetite crystals covered in biological material called magnetosomes. Each nanoparticle is about 100,000 times smaller than a grain of rice. They are mostly found in water and sediment with little or no oxygen. It has been found that magnetosomes can be biodegraded (dissolved) in human stem cells losing magnetism at first but then reforming into human cells with magnetic sensitive qualities.

There is a daily variation in the magnetosphere caused by sunlight hitting the ionosphere, a layer of the atmosphere about 1000km up. The electrical conductivity of this layer is affected by the solar wind which pressures and squashes the field on the sunlit side while creating a magnetotail pluming from the dark side of the Earth.

Capturing garden activity through the solar cycle with a spycam.

The rotation of the Earth around its axis results in a molecular clock evolved by organisms in alignment with the solar cycle. The Earth’s magnetic field can influence animals’ circadian clocks, through the photoreceptor cryptochrome, which is activated by blue light.

I have recently acquired a drone and have been for a couple of practice flights in Richmond Park’s designated area taking along a few pentagon mirrors. Excited by the possibilities.

Up at 5am to see the tiny points of light that are Venus and Jupiter approaching their conjunction which they performed the following morning hidden by clouds

Research trip to RSPB Snettisham in North Norfolk to see the Whirling Wader Spectacle. The high spring tides push the birds from their feeding grounds on the mudflats of The Wash onto the lagoons of the reserve. The spectacle occurs when the tide is super high during daylight hours in early spring or late autumn when the birds are migrating to and from this site. It is surprising how fast the tide comes in. On arrival in the early evening the sea is a distant strip of light.

Suddenly the gullies are filling and the first murmurations of knots are forming low over the incoming water. The speed of the birds is extraordinary. I was totally ill equipped to capture the spectacle on video.

Fascinating research discussed in the webinar Scientific American live: Bird Migration and Song featuring Professor of Chemistry University of Oxford, Peter Hore, an expert on magnetoreception.

Radicals are molecules that contain an odd number of electrons and are therefore unstable. For most molecules the electrons are paired which cancels out the magnetic force. Birds use three different compasses to navigate across the globe; the sun, the stars and the magnetic field. The Artic tern makes the longest migratory journey, a staggering 25,000 miles.

The theory that birds may use the Earth’s magnetic field to navigate began in the middle of the 19th century, but experiments in Germany with European Robins in the 1960s were the first to prove the connection. The Earth’s magnetic field is extremely weak so the mechanism that can detect this weak force must be very sensitive. Because free radicals are very unstable it doesn’t take much energy to have big effects. The particular cryptochrome molecule used is found in the retina of the eye with the photoreceptor cells. Blue light shined onto Cryptochrome 4 produces radical pairs which are sensitive to the magnetic field. It is excited by blue light but does not respond to red light. The molecules work like a pendant compass, distinguishing the direction of the magnetic field towards pole or equator. This feature arises from the spin direction of the free radical pairs. Both radicals may spin in the same direction or one may spin one way and the other the opposite. There is a lot of processing in the eye before a signal is sent to the brain to act upon.

It is possible birds form a visual perception of the magnetic field. The cone cells in the eye are used by day but may be taken over at night for navigation as this is when birds migrate. Light pollution and electromagnetic noise pollution such as AM radio masts can cause disorientation.

I still have questions about how the birds know where to head for. They may have a map but they still need a destination.

Stunning North Norfolk coastline. It’s so flat here that cliffs are unexpected. Hunstanton Beach was once under a tropical sea 108 million years ago when sea levels were 200m higher. Somewhere in these strata evidence of magnetic pole reversals will be stored.

So much to explore at the National Physical Laboratory Open Day but my favourite room was Magnetic Materials and Sensors. They don’t allow any photography so I can’t share some of the amazing experiments I saw but I have been able to recreate my favourite as it was also the simplest; a magnet dropped into a copper pipe creates an electric current as it falls which gently slows its progress through the tube. So cool. I will be filming this.

Experiments with lenses. It’s often the way that having spent time on a proposal that doesn’t get accepted those ideas do not get wasted but ultimately feed into new work.

Testing ‘The Forms’ as a floor piece.

The immutable truths Plato discovered in geometry belong to the realm of abstract thought and ideals he called The Forms. Twelve pentagons form a dodecahedron which Plato defined as ‘a fifth construction, which the god used for embroidering the constellations on the whole heaven.’ Today it is dark matter that science believes holds the stars in the heavens. In visualisations of dark matter created from cosmological data we see familiar organic patterns emerge; the fronds of dark matter spanning between galaxies could be the spreading branches of trees or the veins under our skin.

Thanks to KIPAC Stanford University for the data visualisations.

Enjoyed a one day 3D Geometry class with Leila Dear at the Princes School of Traditional Arts. I gained so much from the RCA exchange week here that fed into my work for the past several years that I thought a refresher would be useful – and that was before I knew we would be making geometric bubbles. Irresistible.

All works offer up a satisfying conjunction of materiality and form but especially loving Nicola’s ‘Quite a Structure’ which is like a slice of the Earth’s molten core.

HEAVEN NEITHER BURNING FARTHER at The Crypt, St. John on Bethnal Green

Erika Blumenfeld writes “The material comprising our bodies shares cosmic origins with the material comprising the planets, asteroids and comets in our solar system. Scientifically, this material, having derived from distant stars across time, threads back to the primordial material that emerged moments after our universe burst into being. Culturally, our star gazing has filled us with wonder across all civilizations, sparking art and architecture, philosophy and science, mythology, folklore as well as navigation and place-making”.

Visual journeys have been created using the archive, modern science, performative poetry, scanned glacier-ice sent by image transmission, laser-based mapping originally sourced from the Rosetta space mission, the use of historic adaptations, the layering of earthly minerals, and a hunt for asteroid fragments. Held in a crypt under-ground the exhibition takes a poignant look at the myth and science that surround comets, which in theory brought life to Earth but could also end it.

Fascinating and beautiful work in this subterranean gateway to the cosmos which rewards following up each artist’s research.

POST TOTEM at OHSH Projects pop up on Oxford Street, curated by Adam Dix and Dale Adcock.
I found the concept of this exhibition very appealing. Reaching back to what connects us. Some innate sense of the sacred.

‘Imagine an artist holding the metaphorical hand of an artist from the previous generation and that artist, doing the same, and so on, back through time, back 30 to 40 thousand years into the unimaginably distant past, when we made the great cave paintings of Lascaux and Maros-Pangkep karst. This imaginative exercise creates an image of an unbroken woven human connection, stretching back through time uniting, individuals into a group, linked by imagination, action and materials.’

Artists showing: Dale Adcock, Simon Burton, Adam Dix, Tim Ellis, Lisa Ivory, Simon Burton, Rachel Howard, Henry Hussey, Dean Melbourne, Yelena Popova, Chantal Powell, Joanna Rajkowska, Alexis Soul Gray, Suzanne Treister.

An interesting entanglement of hand and digital process. Raw paintings are photographed and imported to a 3D digital space of geometric shapes, tubes and directional lighting. The effects are then exported and printed onto the original painting.

Questioning the mediation of the mountain experience. A mountain skyline created from album covers and soundscape from the combined mix of recorded content. Imagine a steady build of music to accompany the climb to a dramatic mountain peak and the overwhelming crescendo as you reach that majestic summit of the sublime. Downstairs choreographed snowploughs score grooves in looping folkdance sequence.

This painting by Luchita Hurtado at Hauser and Wirth made me think of the practical demonstration by Brian Cox showing that in a vacuum a feather and a rock (bowling ball) would fall at the same speed.

 “The reason the bowling ball and the feather fall together is because they’re not falling. They are standing still. There is no force acting on them at all.”

“(Einstein) reasoned that if you couldn’t see the background, there would be no way of knowing that the ball and the feathers were accelerating toward the Earth.”

Everything is Made of Light at Bermondsey Project Space. The artists refer to Jacques Rancière, in his essay, Are Some Things Unrepresentable?, who scrutinizes the challenges faced by images in depicting the world around us.

Mark Kasumovic tackles the problem of trying to represent the invisible through a juxtaposition of images of spaces of discovery and text listing scientific non sequiturs. Mary O’Neill presents us with a world of fragments from which personal narratives must be assembled. Isabella Streffen’s work explores perception and the spaces between digital and emotional communication. Matthew Pell stretches time through capturing light in otherwise transient momentary events.

I felt very in tune with intent of the work here. Particularly Mark Kasumovic’s texts that felt like a snapshot of a research artist’s notebook. All those tantalising lines of enquiry. I liked the premise from Mary O’Neill of the introduction of creatures from the mundanity of an overlooked life, that when situated in a new context, conceive paradise.
