The footsteps of Magnes

October 5, 2025 //

In Pliny’s Natural History (published after his death in the AD 79 eruption of Vesuvius, when, ever curious, he had gone to investigate the strange cloud rising), he marvels at the powers of the magnet ‘For what, in fact, is there endowed with more marvellous properties than this?’; ‘What is there in existence more inert than a piece of rigid stone? And yet, behold! Nature has endowed stone with both sense and hands! He goes on to assert that ‘it received its name “magnes”, Nicander informs us, by the person who was the first to discover it, upon Ida’. ‘Magnes, it is said, made this discovery, when, upon taking his herds to pasture, he found that the nails of his shoes and the iron ferrel of his staff adhered to the ground.’

Nicander was a 2nd century BC Greek poet, physician, and grammarian and there is no surviving record of his claim. Gillian Turner, in her book North Pole, South Pole, admits that this story will have been embellished over time but acknowledges that if an electrical storm took place on Mount Ida and the naturally magnetic magnetite was struck by lightning, it would be permanently magnetised into lodestone and would therefore attract the nails of Magnes’s shoes.

The legend is not impossible but it is also possible the stone is named after the region where it was first found. In ancient Greek, magnetite was known as magnes lithos. There were two ancient regions called Magnesia and so the true provenance of the first discovery of the lodestone is hard to determine. In Greece, ancient Magnesia was a long and narrow slip of country in Thessaly between Mounts Ossa and Pelion. Around the 4th Century BC, the people known as Magnetes, migrated and settled in Ionian cities which were named after them as Magnesia on the Maeander and the neighbouring Magnesia ad Sipylum, currently in Aydın Province near Ephesus, Turkey.

I decided to follow the footsteps of Magnes.

Mount Ida is famous in Greek Mythology as the location for the Judgement of Paris, where he fatefully chose Aphrodite as the most beautiful goddess, setting in motion the events of the Trojan War which the gods watched from its summit while its fir trees were felled to build the Trojan Horse. It was also an ancient sacred site for worship of the mother goddess Cybele, an embodiment of a universal Mother Earth. Its name was changed to Kazdağı (Goose Mountain) as the goose holds sacred significance in Turkish mythology. The landscape is literally breath-taking with very high oxygen levels due to the extensive pine forests and unique geographic features that funnel ionised air up from the sea to mix with the clear mountain air.

Setting out on the first evening the walk to view the mountain brought home the vastness of the landscape to negotiate.

After dinner, the owner of our hotel in Zeytinli said he would find a guide to the area if we gave him 5 minutes. Thinking he would come back with a book of hiking trails, I was surprised when he returned with a Kazdağı National Park Ranger. We arranged to meet the next day when he led us up the dusty mountain tracks with his old school friend as driver.

The summit of Mount Ida was always in the distance and it is not possible to walk unaccompanied in the National Park during the summer season. We drove up to a height of 800m to view the spectacular Sahinderesi Canyon.

Mount Ida abounds with fresh water springs, rivers, ponds and waterfalls including the Sütüven Waterfall which we visited.

We visited the Ida Madra Geopark Museum which displayed tantalising exhibits of magnetite crystal and volcanic rock but there was only a security guard on duty who could offer no information about the collection or the local geology. The magnetite crystal does look like a broken magnet rather than raw crystal.

Fascinating choice of sentence to describe magnetite in the Turkish-English online dictionary – ‘Category, Turkish, English. Technical. 1, Technical, manyetit · magnetite n. The enzyme dissolved the brain tissue and left the magnetite particles intact.‘

Outside the museum was a tomb that our guide told us is called ‘the man eating stone’. Pliny also talks about a stone called sarcophagus (stone of Assos) of which he says ‘It is a well-known fact, that dead bodies, when buried in this stone, are consumed in the course of forty days, which the sole exception of the teeth.’ There was also a magnificent Oriental Plane Tree, over 570 years old.

We visited the wonderfully eccentric Tahtakuşlar Ethnographic Museum which celebrates the cultural heritage of nomadic Turkish tribes and displays a stone tablet inscribed with the symbol of a goose foot reflecting the veneration of the goose by the Turkmen people. There is a rather faded model of Mount Ida which apparently shows the line of a mysterious ancient structure that circles the summit.

The next day we made another winding ascent. Equipped with my own magnet sphere (terrella) I went in search of magnetite on the foothills of Mount Ida. I was thrilled to discover some rocks that were magnetic.

The final evening in northwest Turkey was spent watching the light fade over Mount Ida as bats and hedgehogs made an appearance along with quite a lot of street dogs that were thankfully more interested in barking at each other.

On to the urban geology of Istanbul and a number of monolithic erections. In the Hippodrome, once a vast public arena for chariot races, imperial ceremonies, and public events, there are several examples of phallic architecture.

The towering red granite Obelisk of Theodosius, originally 30m tall, is an ancient Egyptian obelisk of Pharaoh Thutmose III (1479–1425 BC), first erected at Karnak to celebrate victory in battle. It was removed from Karnak and transported along the river Nile to Alexandria by the Roman emperor Constantias II in 357 and just 33 years later Theodosius I had it transported to Constantinople and erected on the spina of the Hippodrome, the relocation upheavals having reduced its height by a number of metres.

It is not known exactly when The Walled Obelisk was constructed but was probably built to mirror the Obelisk of Theodosius in the Hippodrome. Obelisks were often erected in symmetrical pairs. It was originally decorated with gilded bronze plaques (maybe to hide the fact that it wasn’t a true obelisk which should be hewn from a single piece of rock) but these were removed and melted down by Christian crusaders in 1204.

The Serpent Column is the remains of an ancient bronze column that was part of a Greek sacrificial tripod originally built in Delphi 478 BC as an offering to Apollo but relocated to Constantinople in 324.

The stone Milion was a marker from which all distances across the Roman Empire were measured. Erected by Septimius Severus upon the re-founding of Byzantium as Constantinople in 330 AD it became the starting-place for the measurement of distances for all roads leading to the cities of the Eastern Roman Empire.

The Column of the Goths, a single block of marble 18.5 metres high, erected in Gulhane Park, is the oldest monument still standing from Roman times.

The Basilica Cistern is a vast subterranean forest of columns with the 4th Century ‘Tear Column’ standing out for its unique patterns which are often thought of as tears but may actually be a stylised representation of a tree.

The Basilica Cistern is the largest of several hundred ancient cisterns that lie beneath Istanbul, built in the 6th century during the reign of Byzantine emperor Justinian I to supply the city with drinking water. The ceiling is supported by a 336 marble columns, each 9 metres high which appear to have been recycled from the ruins of older buildings and are carved out of different types of marble and granite.

Two columns reuse blocks carved with the face of Medusa. Tradition has it that the blocks are oriented sideways and inverted in order to negate the power of the Gorgon which held that anyone who looked upon her was turned to stone.

The Sacred Trust, of Islamic religious relics kept at the Topkapi Palace includes the Casing for the Black Stone, a rock set into the eastern corner of the Kaaba, in Mecca, Saudi Arabia. Revered by Muslims as an relic which, according to tradition, was set intact into the Kaaba’s wall by Muhammad before he became a prophet. It has had a turbulent history, being stolen, taken hostage and smashed. Today its fragments can be seen set in cement, encased in a silver frame on the side of the Kaaba, polished smooth by the hands and kisses of pilgrims. Although idolatry is forbidden in the Hebrew Bible and the Quran the use of aniconic stones, or baetyls, which are sacred stones stones venerated for their connection to the divine, without needing human-crafted images, were permitted. There has been speculation The Black Stone is a meteorite, but it has never been scientifically analysed to ascertain its physical origin. Also on display are footprints in stone (Kadem-i Şerif) attributed to the prophet Muhammad. An Ottoman scholar, Mehmed Münib Ayıntâbî (d. 1823) wrote a treatise to explain that this footprint was one of the miracles of the Prophet for otherwise how could it be possible to leave the impression of a foot on hard ground like stones. This was reiterated by a guide at the palace. There are six Kadem-i Şerif of the Prophet four of which are on stone and two of which are on brick, the most significant is the one in a gold frame believed to be left on his ascension to heaven from the Dome of the Rock.

Mechanical clocks didn’t arrive in Ottoman lands until the 15th Century, 200 years after their initial invention. Chief astronomer to Sultan Selim II, Taqi al-Din, bemoaned the new instruments as ‘the most burdensome to construct, which demanded modest workers’. The qibla compass was used to determine the direction for prayer. This Ottoman marble sundial is from 1526.

‘Were man to look up from the ground, he’d see a starry sky, were he to look down from the heavens – a wavy sea’ Tursun Beg. (15th century Ottoman historian who wrote a detailed account of Mehmed the Conqueror’s reign.)

The 1513 world map made by Turkish cartographer Pîrî Reis was discovered in the Topkapı Palace Library in 1929. Pîrî Reis created an impressively accurate depiction of the newly discovered regions of the world using a circular design based on a hypothetical centre. This map is the earliest cartographic record of Columbus’s oceanic voyages and the first to show the unique fauna of Terra Australis.

Beginning new work. Learning about the symbolism of sacred geometry in the Westminster Abbey Cosmati Pavement has inspired me to think about how I could relate ancient symbolism and contemporary iconography to think about changing relationships to fire, water, earth, air and the cosmos. Plato imagined the universe was created as a living creature in the shape of a sphere, perfect and complete in itself. Patterns of Thought author Richard Foster suggests that ‘as our minds become progressively tuned to ecological and global concerns, so the Platonic image of the world as a living creature is re-awakened from its sleep.’

In the symbolism of the Cosmati Pavement, the journey from earthly materialism to spirituality is seen as a progression from multiplicity and diversity towards unity and uniformity. The tiles show a transition from a variety of patterns through to simplified regular polygons, the archetypes of form representing a perfection that we only experience as a shadow on Earth. Random patterns at the centre of the design describe the elements in an undifferentiated state of matter, the primal chaos before the division of spirit and matter when the breath of the creator swept over the ‘turbulent waters’ or ‘silva’ bringing forth the differentiation of matter into the forms of the four elements. The medieval mind never took the world at face value and always sought to see the coexistent and equally valid layers of meaning in everything.

In medieval cosmology the separation of the elements happened before the advent of time which began with the creation of the sun, the moon and the planets as astronomical time, the timelessness of eternity is alluded to by the number 60 + 1. The end of the world was imagined as a reversal of creation. All will return into the four elements which return to the primal chaos and are reabsorbed into the divine mind and eternity.

The four elements are linked by pairs of opposing qualities: Fire is dry and hot; Air is hot and moist; Water is moist and cold; Earth is cold and dry. Each element shares a quality with two others and elements with a shared quality combine more easily. Fire is sharp, tenuous and mobile, reflected in a quick tempered choleric human temperament, it gives vision and belongs to the heavenly race of gods. Earth is blunt, weighty and immobile reflected in a heavy melancholic human temperament. Earth resides with the sense of touch and those that walk on the ground. It has stability facing to the north, south, east, west, zenith and nadir. Air is sharp, mobile and weighty reflected in a breezy optimistic human temperament. Air amplifies hearing and smell, it supports the flying creatures and is synonymous with breath and spirit. Water is mobile, blunt and weighty reflected in a dissolute easy-going human temperament. Water amplifies taste and supports the creatures that swim.

I was interested to read that in the kitchens of the Topkapi Palace (1459) in Istanbul, the four humours (blood, phlegm, black bile and yellow bile) were taken into account when designing the menus. Different foods were recommended depending on their qualities to restore good health for those suffering sickness which was attributed to an imbalance of the humours. The seasons were also taken into account in relation to the humours when deciding which foods to cook.

Gallery Visits

Deeper Beneath at the stunning 1500 year old Basilica Cistern Museum includes work by Vlastimil Beranek (Aqua One- Yellow – made from Bohemian Crystal), Jaroslav Prosek ( 6500 year old subfossil oak), Ali Abayoğlu (Glass Leaves and Jellyfish) and Muzaffer Tuncer (Seclusion)

Åsa Jungnelius A Verse, Written with Earth, Fire, Water and Air at Pera Museum, Istanbul. The exhibition brings together the results of time spent in the obsidian fields of Eastern Anatolia collecting natural glass formed by the rapid cooling of volcanic lava and working in the glass furnaces of Denizli along with reflections on marble steeped in Byzantine history. Archaeological finds, glass objects, materials, and handwoven cords rooted in nomadic traditions are displayed alongside photographs by Swedish photographer Peo Olsson documenting the artist’s research. There is a strange juxtaposition of the installation scaffolding set against thick carpet in the gallery.

Also at the Pera Museum was Feelings in Common: Works from the British Council Collection. The exhibition is striving to form a zone where feelings in common are shared amidst uncertainties and transformations regarding the future. Happy to see Bedwyr Williams The Starry Messenger again (image 1 + 2 – the poignant geological story of a mosaic dentist which alludes to the micro macro scales of the universe ) and Larry Achiampong’s Relic 2 (an Afrofuturist exploration of postcolonial identities, imagined futures, and ancestral memory) along with a small work from Raqib Shaw from his Garden of Earthly Delights series amongst other works.

The VoiceLine by composer and sound artist Nick Ryan installed in the atmospheric Deadhouse, Somerset House. 39 precisely aligned speakers, creating an evolving pathway of sound reflecting the histories of radio and listening that began on the Strand more than a century ago.

An exhibition by KitMapper, an artist led production company, Along More Latent Lines at Somerset House to showcase new and recent works of the team and creatives based here including the interactive and immersive Genetic Moo: Magic by Genetic Moo.

Jane and Louise Wilson Performance of Entrapment at The London Mithraeum Bloomberg Space featuring 2,000 year old oak stakes that inspired imagery looking at structure and ritual. The works investigates parallels between the sacred sites of Mithras and Japan’s Ise Jingu Shrine.

Treen (of a tree) was a collaborative event between Liz Botterill, Sevenoaks museum curator and the Kaleidoscope Gallery co-curators Rosalind Barker and Sue Evans, with the artists of Sevenoaks Visual Arts Forum. The artists were invited to respond to items in Sevenoaks Museum that are made of wood. Participating artists: Colin Anderson, Carole Aston, Jocelyn Bailey, Rosalind Barker, Susanne Beard, Sarah Cliff, Christina Crews, Louisa Crispin, Margaret Devitt, Louisa Donovan, Duncan Dwinell, Sally Eldars, Sue Evans, Deborah Farquarson, Victoria Granville, Kate Grimes, Amanda Hopkins, Marilyn Kyle, Keith Lovegrove, Venetia Nevill, Clare Revolta, Franny Swann and Irene Vaughan. Venetia Nevill worked outside the remit to create ‘Memories of a tree’ to honour a plantation of spruce trees that have been felled, because they were infected by the spruce beetle. Her process of wrapping a cloth around a tree, and rubbing the burnt soil, ash and charcoal into it, memorialises and commemorates the trees. Over a few months the cloth absorbed the sunlight, birdsong and passing of time, allowing the elements to leave their mark, and create a cloak of protection. The cloth is exhibited along with burnt remains of trees.

Reading

North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth’s Magnetism by Gillian Turner. A very readable account of all the philosophers, explorers and scientists fascinated by the origin of Earth’s magnetism, from the earliest speculations of lodestone mountains, magnetic polar stars to seismology and deep ocean core sampling revealing the inner working of the planet.

Turning to Stone by Marcia Bjornerud. This book is the antithesis of the idiom ‘as cold as a stone’. It is a passionate and candid account of relationships between humans and rocks. Human to human, human to rock, rock to human and rock to rock. Along the way we learn a lot about geology and the human condition.

In classical antiquity, a time stretching from Homer to the early middle ages, geographic orientation usually referred to landmarks or astral phenomena to determine direction. Eos, meaning dawn, and Hesperus, meaning evening, were named for sunrise and sunset with north (arctos) being marked by the constellation Ursa Major and later the Pole Star. The winds also became associated with direction and named in accordance with their qualities such as hot and humid or cold and dry.

The number of points on a wind rose began with the four cardinal points that were added to and refined over time. Aristotle designed an asymmetrical 10 point wind rose for “the study of things high in the air” (meteorology) which was later refigured by Timosthenes, a 3rd century BCE Admiral and geographer, naming a system of twelve winds and using this as a tool for navigation. The contemporary compass has its roots in the ancient classification of winds.

Freshly excavated. A new tablet for the series Instruments of the Anemoi, replacing a previous one based on the idea of a wind rose and set with etched copper markers, the designs of which are influenced by characteristics of the gods (anemoi) represented by each of the twelve winds.

Instruments of the Anemoi are a set of dodecagon tablets cast in Snowcrete, a cement with no magnetic minerals, as is used for instrument pedestals at a magnetic observatory. They also respond to a twelve sided anemoscope “table of the winds” carved in marble around eighteen hundred years ago and held at the Vatican Museums. Releasing the cast from the mould and collagraph is a rewarding process – if all the pieces have held their position during the concrete pour and vibrating to release trapped air bubbles. Luckily this time was a success.

The other two sculptures in the series. A hand beaten 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 155. Wafer thin fish shaped iron leaves were also used by 11th century Chinese geomancers. Nails and iron filings reveal an embedded magnetic field and hark back to a legend on the discovery of the lodestone, a naturally magnetic mineral, which recalls a Greek shepherd who noticed the nails in his boots were attracted to the rock beneath his feet.

Unsettling to find it is already one year on since A Stone Sky duo exhibition with Julie F Hill opened at Thames-side Studios Gallery and this work was first shown.

Around 95% of the universe is ‘dark’ to us, formed of unknown and possibly unknowable matter which may be inaccessible to us, but cosmic rays offer a tangible contact with outer space.   

Giving The Breath of Stars a run to see if the cosmic rays are still there 😉 These images are stills of live action.

Cosmic ray detectors, mini computers, wooden box (20 x20 cm), video projection; live duration.

The Breath of Stars is a digital video work activated in real time by cosmic rays. These high energy particles arrive from outer space, interacting with life and technology on Earth. Coming from the heart of exploding stars or the depths of black holes, cosmic rays power across the universe with unimaginable energy. Some may come from phenomena yet to be discovered or even from other dimensions. A kaleidoscopic animation is projected every time a cosmic ray is recorded passing through the detectors. The animations are created from footage of cosmic ray trails filmed in my cloud chamber.

This cold damp weather is stimulating the moss regrowth on the apex pinnacle of The Absolute Hut (of action potential) that found a space in my garden after The Stone Sky exhibition this time last year. I had spent weeks preparing the recycled fence boards to make the North facing wall of the hut, painting them with various mixtures of buttermilk and yogurt blended with moss and was so excited when it began to grow. During the exhibition I would mist it every day. The beginning of my fascination with huts!

Operating as a sensory hub 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. Neurons in the brain and nervous system 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.

A year on and the pyramidion that sits on top of The Azimuth Obelisk (of sedimentary knowledge) is evolving. The patination, which involved a variety of chemicals being applied to the copper in layers, is an ongoing process.

Sedimentary rock holds a geological history of the Earth’s magnetic field within its mineral components. 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 artefacts, volcanic rocks, and sediments. Limestone, a sedimentary rock, is often formed from crushed seashells, compressed over aeons. Crushed oyster shells were added to the obelisk base cast in Snowcrete.

This sculpture also embodies the passage of time, and a layering of information, in the months of collecting paper donations or scavenging the recycling bins, weeks tearing down the hundreds of prints and drawings into squares decreasing by 1mm every 50 sheets, drilling holes through the centre and hours to build the almost 3m stack. I’m very grateful to everyone who donated some of their work archive. These images are now secreted within the layers of the sculpture, hinted at where edges are exposed, echoing the Earth’s sedimentary knowledge.

The Azimuth Obelisk (of sedimentary knowledge) Paper, steel, Snowcrete, oyster shells, patinated copper; 30 x 30 x 270 cm

 This work is a reimagining of an ‘obelisk’ erected at Hartland Magnetic Observatory in the late 1950’s to be viewed through the north facing window of The Absolute Hut, it acts as a permanent azimuth mark from which the drift of the magnetic north pole is monitored. I am excited that this sculpture is being considered for exhibition in 2026 at the Royal West of England Academy in Cosmos: The Art of Observing Space curated by Ione Parkin with some amazing artists in the line up whose work I admire.

I first came across directional magnetic steel in the Electronic & Magnetic Materials Group open day at the National Physical Laboratory. Intrigued, I wanted to know if I could get hold of some to work with. I was put in touch with Union Steel Products who were very helpful in supplying a small amount (to them) of the material, but they import the product, and it arrives with an indeterminate protective matt grey coating. This was my challenge. It took many days of sanding and gently etching each sheet to reveal the pattern. It was a very temperamental material to work with, the pattern might appear but quickly tarnish and muddy over. So much of the work in the resulting sculpture was about the process of exposing an internal mechanism.

The dramatic Widmannstätten patterns found in meteorites due to their slow evolution through heat and pressure are also revealed through being cut, polished, and etched.

These secrets are not revealed lightly.

Domain of the Devil Valley Master

This work 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. 

Work in progress. Mapping a response to the crystal structure of magnetite. Magnetite is the most magnetic of all the naturally occurring minerals on Earth found in igneous, metamorphic, and sedimentary rocks. Nano-particles are also found in the human brain, heart, liver, and spleen and the cells of many other organisms, with some creatures using this for navigation techniques.

Magnetite crystals from road traffic pollution caused predominantly by vehicle frictional braking systems can outnumber natural magnetite in the human brain by 100:1 – this is a worrying trend as these crystals could be involved in our perception, transduction, and long-term storage of information in the brain.

Returning to my conversation with Alan Watson on the history of Haverah Park Extensive Air Shower Array.

The motivation for the Haverah Park project getting off the ground came largely from the British physicist Patrick Blackett, who won the Nobel prize in 1948 for his discoveries in the field of cosmic rays. The director of The Rutherford Lab (where the British atomic bomb was being developed in the 50’s), John Cockcroft (known for splitting the atom), decided there should be fundamental science going on as well as bomb building, so outside the security wire they built an air shower array to monitor cosmic rays. When this experiment was shut down, Blackett was keen to see work with shower arrays continue, and to be within reach of a university so that scientists could combine research with teaching. Blackett was working at Cavendish Laboratory with Ernest Rutherford, but moved to Birkbeck which did all the teaching in the evening so he could do research work through the day and teach in the evening. Here he met J G Wilson, also with an interest in cosmic rays, so when J G Wilson later moved to Leeds, Blackett suggested he set up an air shower array there, which was how the Haverah Park Project came about. Land was rented from local sheep farmers to install the observation huts.

Alan Watson took a lectureship job at Leeds in 1964 and began working for J G Wilson, becoming a leading member of the UK Extensive Air Shower project until its closure in the early 1990s.

We also talked about the mesmerizing power of a cloud chamber. As well as it being considered one of the most important developments for progression in the understanding of particle physics it is also emotionally and aesthetically captivating. Alan reminisced about a time at the Royal Society Summer Exhibition when a large commercial diffusion cloud chamber drew so much attention they were asked to turn it off, as mesmerised visitors blocked the entrance to the exhibition. It’s been a few years since I visited the Institute of Physics to see the large cloud chamber in the foyer, I wonder if it’s still there. I love the fact that I can build my own cloud chamber to see these cosmic visitors.

J G Wilson writing on the study of cosmic rays from his book About Cosmic Rays published in 1948, of which I have a copy:

‘It has its spectacular side, for the only laboratory which has been found big enough for its investigations is the whole of the universe to which men can win access. Most refined measurements have been made under conditions of difficulty and hazard, deep in mines and on icebound mountains, in the watses of western Greenland and cramped in the tiny gondola of a stratosphere balloon. These exploits, which are outstanding even in one of the most brilliant phases of experimental physics, are an unambiguous indication of the importance which is attached to the problems which are being studied.’

The following images from the same book show particle trails photographed in a cloud chamber -showing extensive showers and particles passing unhindered through metal plates.

J G Wilson writes about cosmic rays ‘…it is interesting to speculate on their previous history, for before it is overtaken by the catastrophe of hitting the earth, each particle is likely to have had a placid life for years, even millions of years, cruising through the wide open spaces of the universe’.

Cosmic Chiasmus: crossing the universe 2021 (video still)

The primary detectors used at Haverah Park were water Cherenkov detectors. These are large water filled tanks filled with a photomultiplier suspended in the water to capture flashes of Cherenkov light emitted by high energy cosmic rays as they pass through. The light is emitted because the cosmic rays pass through water faster than photons of light are able to, and as they do so they lose electrons thereby emitting light. The speed of light is only a constant within a vacuum, when it passes through other materials it get slowed down.

There were four 34 m2 detectors at the centre of the array in the main hut, with three detectors located 500m from the central detector. Signals from the three distant detectors were sent along buried cables to the central hut, with the signal from the central detector passing down 500 m of cable buried underground so that all signals arrived at about the same time.  When signals from the central one and two of the others arrived within ~2 x 10-6 s (called a coincidence), the signals from the photomultipliers in the 34 m2 detectors were displayed on four oscilloscope screens and photographed by one camera which had its shutter permanently open. About 20 feet of film could record around 150 events. Developed and manually scanned by Alan, or a senior colleague, the film was checked for quality and to look for any large events (ultra high energy particles arriving) which were always exciting to find. The developed film was then sent to Leeds University Physics dept for measurements.

When there was a coincidence event at the centre of the array, a signal was sent by microwave to the distant detectors set across the moorlands (on average about 2km from the central hut), the signals from these distant groups of 4 x 13.5 m2 were recorded digitally with the data going onto paper tape which was collected once each week. 

Along with the oscilloscope traces being photographed, the number on a counter was included which gave the time of each event to the nearest half minute.  In the 1960’s when this project began the time counter was advanced by a pendulum clock.  Counting time in half minutes the team found that there are roughly one million half-minutes in a year, which gave a good excuse for an annual party.

There were some brief periods in the early 1980s when a small number of scintillator detectors were also used to make cross-checks of the results from the water Cherenkov detectors against those from projects in the USA (Volcano Ranch) and Yakutsk (Siberia).  The scintillators retrieved from Imperial College’s Holborn project were brought to Haverah Park for an experiment to look at much lower energy showers.

Both types of detectors register flashes of light.  

Blackett was the first person to work out the details of Cherenkov light produced in the atmosphere. According to a memoir on Blackett, written by astronomer Bernard Lovell, who knew him very well, Blackett attempted to see Cherenkov light from cosmic ray showers with the naked eye but there is no mention of whether he succeeded. In 1962, physicist Neil Porter who built the first water Cherenkov tank in the UK at Harwell in the 50’s, did an experiment with some volunteers who were asked to recline on a coach in a dark room with a small Geiger telescope attached to a pair of darkened goggles and acknowledge if they saw a flash of light when a cosmic ray was known to pass through the googles. The observers did seem to experience a flash of light but results were ambiguous as to whether this was Cherenkov light being emitted as the particle passed though the crystalline lens or vitreous humour of the eye or a direct excitation of the retina. The experiment was a collaboration with the Psychology dept at the University of Dublin and published in Nature under the Psychology heading giving an impression that the lights were perhaps a figment of the imagination.

Astronauts are very aware of this phenomenon. During the 1970 Apollo 13 mission to the moon the power supply was damaged and the astronauts sat in the dark for several days waiting to return to Earth. They experienced flashes in their eyes and realized that some of this was Cherenkov light. Some flashes were caused by particles directly hitting the retina but Cherenkov light caused by high energy particles travelling through the matter of the eye faster than light, is much brighter. The energy is proportional to the square of the charge of the particle that comes through, so if you have an iron nucleus which has a charge 26 x the charge of a proton, you get 26 squared or 600 times as much light emitted. Out in space there are many more of these high energy particles and so the astronauts would become very familiar with these flashes, even using them to line up accelerator beams by putting their head in the particle beam to see the flashes.

An astronaut once told Alan that he was convinced that the very first people fired into space probably saw these flashes, but didn’t like to tell NASA in case it turned out to be a physiological defect of theirs and they would be taken off the space programme.

Recently, a professor friend of Alan’s who is aware of this phenomenon, has unfortunately had to begin radiation treatment for a brain tumour. He has found due to the position of the tumour and angle of treatment he can see Cherenkov light flashing in his eyes as the electrons bombard the tumour.

When we met, Alan was just back from a conference in Italy discussing a paper titled ‘Ultra high energy cosmic rays: The Disappointing model’. They called it the disappointing model because they believed that the Auger results with particles at the highest energy were heavy not protons. I’m not sure I understood why it was disappointing although Alan did his best to explain: ‘It’s difficult to measure the mass of the particles of a certain energy. A deduction had been made that they have a mean mass, probably the same as nitrogen but mass changes in quite a complicated way as a function of energy. It’s to do with how deep the showers develop in the atmosphere.

The techniques aren’t good enough to separate the particle’s mass on a one by one basis, we can only do averages. It looks like the average mass is much heavier than protons, which everybody had believed for a long, long time. Protons would be at a much lower energy. As the nucleus is travelling through space, it sees photons from the microwave background radiation and the photon will chip off a neutron or a proton, if it chips off a neutron, the neutron decays into a proton, so you can get protons this way, but they will be of lower energy. The energy reduces roughly by the mass of the particle, so an iron nucleus has a mass of 56, if you chip off a neutron or a proton that proton will have an energy, which a 56th of the energy that the nucleus has – so it goes down in energy.

Some particles could come from Centaurus A, which is a relatively close radio galaxy, it is thought that the jets from radio galaxies provide conditions to accelerate the particles, but the problem is, because the cosmic rays are charged, they get deflected in the magnetic field of the Galaxy so you can’t track them straight back to where they came from.  In terms of heavy particles that’s more of a problem because being charged means they bend even more. So one of the disappointing things is that cosmic ray astronomy is not going to be very easy. The Pierre Auger observatory has really been very successful in changing the picture quite a bit but because there are so few ultra high energy particles recorded it is slow progress. There are hopes to expand the observatory even more and also a plan to launch a satellite with detectors to pick up fluorescence light in the shower as it passes through the atmosphere, a similar phenomenon to aurora light.

Exhibitions

The Vinyl Factory: Reverb at 180 The Strand, a multimedia exhibition exploring the intersection of art and sound with artists including Theaster Gates, Es Devlin, Julianknxx, Kahlil Joseph, Caterina Barbieri, Stan Douglas, Virgil Abloh, Cecilia Bengolea, Jeremy Deller, William Kentridge, Jenn Nkiru, Hito Steyerl, Carsten Nicolai and Gabriel Moses. Fabulous show, shame I can’t share the sounds here. Loved Jeremy Deller’s takeover of a sixth form politics class. Some of the works I had seen before but that was fine as they are worth extra viewings.

Reading

I am beginning research reading for The Geological Unconscious exhibition Julie F Hill and I are co-curating at Hypha HQ Euston opening in May 2025.

Ursula Le Guin The Winds Twelve Quarters, a collection of profound short stories each introduced by the author reflecting on the intention within.

Long after I wrote the story (The Stars Below) I came on a passage in Jung’s On the Nature of the Psyche: ‘We would do well to think of ego-consciousness as being surrounded by a multitude of little luminosities…Introspective intuitions…capture the state of the unconscious: The star-strewn heavens, stars reflected in dark water, nuggets of gold or golden sand scattered in black earth.’ And he quotes from an alchemist, ‘Seminate aurum in terrain albam foliatam’ – the precious metal strewn in the layers of white clay. Perhaps the story is not about science, or about art, but about the mind, my mind, any mind, that turns inward to itself.

Roger Caillois The Writing of Stones 1970 is a tribute to the collection of extraordinary stones Caillois acquired and which now resides in The National Museum of Natural History Paris. In these poetic chapters he describes in detail each of the stones and his fascination with the images and associations they conjure in his imagination. Questioning and celebrating the allure of the mineral and the stories hidden and revealed over millennia.

I can scarcely refrain from suspecting some ancient, diffused magnetism; a call from the centre of things; a dim, almost lost memory. or perhaps a presentiment, pointless in so puny a being, of a universal syntax.

A Stone Sky

December 12, 2023 //

‘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 Gallery – Reimagining 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.

Installation shot by Ben Deakin Photography.

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.

Gallery Visits

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.

It is within my mind then, that I measure time. I must not allow my mind to insist that time is something objective.  When I measure time, I am measuring something in the present of my mind. St. Augustine of Hippo, 397

The many layers of paper comprising The Azimuth Obelisk (of sedimentary knowledge) sculpture have been prepared ready for final assembly. The next step will be patinating and assembling the copper pyramidion. This sculpture is a reimagining of the obelisk erected at Hartland Magnetic Observatory in 1955 which is now almost hidden by undergrowth. Although manual readings via a theodolite are still taken from the Observing Building north facing window, this concrete permanent azimuth mark has been replaced by a GPS position. 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.

What is below our feet can be as much of a mystery as what is above our heads. The furthest humans have drilled below the surface of the Earth is just over 12 km but it is 6,370 km to the centre of the Earth. One way of exploring the Earth’s core is by studying geoneutrinos. Geoneutrinos are neutrinos, the lightest subatomic particle, released by the natural radioactive decay of potassium, thorium, and uranium in Earth’s interior. By studying geoneutrinos, scientists can better understand the composition and spatial distribution of materials in the mantle and core. Neutrinos can pass through matter uninhibited and are not affected by magnetism. Geoneutrinos are low-energy electron antineutrinos, and scientists need to use large detectors to record them but because they  are so elusive, they don’t capture very many events each year. Some of the heat emanating from the interior of our planet comes from this radioactive decay and is responsible for everything from creating the molten iron core that generates Earth’s magnetic field to the spread of the sea floor and motion of the continents.

At the centre of the Earth is a hot sphere of solid iron which has its own ocean of molten iron, surging and churning with hurricanes and whirlpools powered by the Coriolis forces of Earth’s rotation. These complex motions generate our planet’s magnetosphere. The turbulent dynamo process also means the magnetic field is in a constant state of change and the poles are always on the move. From James Clark Ross first locating the magnetic north pole in 1831 to when Roald Amundsen found the pole again almost a century later it had moved at least 50 km since the days of Ross. Both poles continue to wander as varying speeds. Magnetic stripes around mid-ocean ridges reveal the history of Earth’s magnetic field for millions of years and record magnetic field reversals in the magnetism of ancient rocks. Field reversals come at irregular intervals averaging about 300,000 years with the last one 780,000 years ago. Reversals take a few thousand years to complete, and during that time the magnetic field does not vanish but becomes twisted and tangled with magnetic poles appearing in unaccustomed places. Although in a state of turmoil with possible weak areas it can still protect us from space radiation and solar storms.

I took up membership of London Sculpture Workshop supported by a professional practice and creative development bursary from The Artists Information Company. Great to have access to the facilities here to work on sculptures responding to research visits to magnetic observatories. I had a couple of sessions cutting copper with a plasma gun. The intense heat colours the edges of the metal with blues, yellows and crimsons. Unfortunately some of the colour gets lost when they are lacquered so I have left some without coating this time to see if they lose the colour anyway. These topographical contours which are destined for the installation The Absolute Hut (of action potential), reflect the fluid motion of the Earth’s interior and also the pulsating alpha waves emanating from the human brain subjected to magnetic fields.

I have started editing and gathering together video footage for The Absolute Hut installation. Inside the hut I am planning to have video screens suggesting portals into a modulated web of neural pathways and one larger window with a two way projection film of the migratory pink footed geese at Snettisham in Norfolk. Natural navigation techniques and extra-sensory methods used by the non-human realm will form the basis for speculation as to the ability for humans to perceive the Earth’s magnetic field. 

Following on from concrete casting tuition with Anna Hughes as part of my a-n creative development bursary I have been testing casting concrete with embedded magnets. I had an idea to try removing bubbles from the concrete by putting it on an exercise vibrating plate. The motion is quite violent and undulating and my mix was quite loose so it had an effect like a small wave machine sloshing side to side – there were no bubbles in the results though. These tests are towards making a series 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.

Lichen boundaries seen on a trip to Somerset reminded me of the magnetic domains of the directional magnetic steel when 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.

I had a great time interacting via zoom with volunteer mediators who will serve as conversationalists for visitors who come to the Carbon exhibition at Science Gallery Bengaluru where my video Cosmic Chiasmus: crossing the universe will be shown later in the year. Mediators are an integral part of each exhibition-season at Science Gallery Bengaluru (SGB). By providing each visitor the unique opportunity to deeply engage with the exhibits, events, and programmes, the mediators are at the backbone of our commitment to public engagement at SGB.

The session was designed to gain an understanding of the work to be shown, the process behind its creation, and the key concepts explored in it. Cosmic Chiasmus: crossing the universe offers a glimpse into a subatomic world where cosmic rays travel from distant galaxies to collide and silently interact with atoms and technology on Earth. Not only is all life physically permeated by cosmic rays with the potential for nuclei collisions but some cascading particles smash into atoms of nitrogen to create carbon-14. Carbon-14 then combines with oxygen in the atmosphere to create radioactive carbon-dioxide  – this is ingested by plants and animals through the food cycle. In making the film I was interested in exploring the interconnectedness of ourselves to our wider environment, even outer space and the influence intangible phenomena such as cosmic rays can have on everyday life and human technology.  It is an incredible journey that cosmic rays make, blasted across space, spiralling along magnetic field lines to end up entangled with carbon in our bodies.

Most years have twelve full moons, but as our calendar is not perfectly synchronized with astronomical events, every now and then there is more than one full moon in a month which can be known as a blue moon. It takes the moon 27.3 days to orbit the Earth but about 29.5 days to go through all of its eight phases waxing from new to full and waning back again. We can hope to see a super blue moon next month.

Carey Young’s Plato Contract – only gains status as an artwork once it has been installed, following explicit instructions, in the impact crater, Plato, on the moon.

Royal Society Summer Lates – Interesting new research in the search for dark matter from UCL High Energy Physics team using quantum sensors. Tiny glass spheres levitated in a vacuum and super cooled means these are extremely sensitive to any slight gravitational interaction should dark matter be made of very light particles. Instead of a vast tank of Xenon installed in a disused goldmine this new search for dark matter is quite a contrast in scale.

Also got to cause gravitational lensing with my own body mass and enjoy some splendid cocktails with surreal smoke bubble topping. Love Royal Society events.

Melanie Jackson Rouge Flambé at San Mei Gallery with a fascinating accompanying essay by Esther Leslie. Rouge flambé is a red oxide ceramic glaze with a long history of use, spreading across the globe from its origins in China. Together these works celebrate forces that hold a primordial fascination – fire, colour, alchemy which bridge the scientific with the mythological.

Angela Palmer Deep Time: uncovering our hidden past at Pangolin London. The exhibition explores time through the material history of Great Britain – charting its 3-billion-year lithic timeline to arrive in our current age of the Anthropocene. Featuring the UK’s 16 geological periods, starting with one of the world’s most ancient rocks, the 3-billion-year-old Lewisian Gneiss from the Outer Hebrides. Further stones include 2.5-billion-year-old White Anorthosite sourced in the Outer Hebrides that was also found on the Moon by the astronauts of Apollo 15 in 1971, as well as 66-milion-year-old Northern Irish Black Basalt marking the extinction of the dinosaur. The exhibition also includes teak sculptures salvaged from the ocean where it lay for a century while marine boring insects carved into its surfaces. Many of these works have minimal intervention from the artist in their presentation. The work has been done in the sourcing and extraction.

I attended the UCL Space Domain Summer Celebration. The event was introduced by Victor Buchli – Co-Chair of the UCL Space Domain which draws in researchers from across disciplines whose work touches on space exploration in some way. Guest speakers, artist Lisa Pettibone and poet Simon Barraclough, gave presentations on their work and involvement with the Mullard Space Science Laboratory and subsequent inclusion of work on the Euclid Spacecraft (launched on 1st July 2023) in the form of a plaque depicting ‘The Fingertip Galaxy’ a collaborative project created with hundreds of mission scientists and engineers’ painted fingertips, along with specially commissioned lines from Simon’s poetry. We were privileged to see the very first image sent back from the Euclid Space Telescope whose mission is to map out the dark side of our universe by analyzing billions of galaxies that reside up to about 10 billion light-years away. Every point of light is a galaxy.

Reading

Compass – a story of exploration and innovation by Alan Gurney. Full of fascinating historical anecdotes charting the invention of the magnetic compass for navigation at sea from lodestone floating in a bowl of water to the precision marine liquid compass, gyrocompass and fluxgate compass used today. Although early experiments came under the auspices of scientific expeditions the compass cannot be untangled from its commercial propagation and employment in colonialism and the slave trade. The first ship charted solely for a scientific expedition, The Paramore, launched from The Royal Dockyard at Deptford in 1694, to compass the globe and measure magnetic variation. It was however approved for funding by The Royal Society, Queen Mary and The Admiralty based on the benefits it would bring for navigation and trade. One of the many delays in launching the Paramore was the novel decision of how many guns should be fitted in a ship bound for scientific research. Pirates were at large and nation wars would flare up while ships were out at sea so a friend at launch might be a hostile force at the next harbour without the means for the crew to receive this news before it was too late. Many many lives were lost at sea during these turbulent times through aggression but also shipwrecks from the poor quality, misuse or misinterpretation of the ship’s compass. Magnetic variation, deviation and iron introduced onto the ships meant the compass needle could not be relied upon to show true north. It took centuries to comprehend the unpredictable power of magnetism and the Earth’s magnetic field.

The End of the Universe Gresham Lecture from Professor Katherine Blundell. The relocation of matter. Spacetime is expanding ever faster due to dark energy. Galaxies do not expand as they are held together by gravity. It is the space between galaxies that is getting bigger and will continue until in some distant future astronomers in one galaxy will not be able to see any other galaxies. Black holes eventually evaporate.

Also from Professor Katherine Blundell Cosmic Vision: Fast & Furious.

Cosmic rays are particles that move extremely fast. They are raining down on planet earth all the time. Although they are called rays they are not like photons, as light is made of, as they have mass but they do travel at nearly the speed of light. The kinetic energy in just one particle can be equivalent to the energy of a cricket ball bowled by the fastest bowler on the planet  – so much energy squeezed into one tiny particle gives it a huge velocity. Light travels a thousand billion kilometres in one year – a light year – no object with mass can travel at the speed of light but an ultra-high energy cosmic ray would only lag behind the photon by 100th of the diameter of human hair. Some ultra high energy cosmic ray particles that arrive on Earth have 1000 billion times more energy than particle colliders on earth can generate. These ultra high energy particles are very rare – with only about 1 per square metre per century. We know many cosmic rays come from supernova explosions in distant galaxies especially from what are called starburst galaxies where lots of supernovae are happening. Supernovae expand very very fast into the interstellar medium of their galaxy – this causes shocks as the plasma expands and where there are compressed magnetic fields particles can be accelerated to very high speeds. There is a formula called the Hillas Criterion which states – the maximum velocity a particle can be accelerated to depends on three things –  the strength of the magnetic field  – the speed of the plasma –  and the size of the region over which the acceleration can take place. New research shows that ancient Radio Galaxies such as Centaurus A – which is over 1 million light years across or the smaller Fornax A Galaxy are good candidates for the propagation of the ultra high energy particles as these galaxies have the huge size necessary to allow the particles to gather speed in the giant regions of radio emission which extend well beyond the galaxies visible structure.

The Breath of Stars is a digital video work activated in real time by cosmic rays. These subatomic visitors from outer space are created during super nova explosions or by phenomena we are yet to discover. This work has been a long time coming and the fact that it is working in real time now is thanks to coding genius Jamie Howard who has managed to get a number video files to play simultaneously on one screen. We had to ditch the Raspberry Pi for a Panda Latte to cope with the processing needed. Cosmic particles 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. In this work particle detectors and mini computers are connected to a projector. Every time a cosmic particle passes through the plastic scintillator block inside the detector its energy is recorded via a Silicon photomultiplier and a starburst video is displayed for twelve seconds. The kaleidoscopic video images generated are created from footage of cosmic particle trails filmed in a cloud chamber, split and mirrored twelve ways. The particles arrive randomly and this can be witnessed by the sudden flurries and silent gaps of the video imagery. First test run and the cat loved it.

The South Atlantic Anomaly is a region where the Earth’s magnetic field is at its weakest. The intensity of the field here is about one third of that near the magnetic poles. This affects how close to the Earth energetic charged particles (cosmic rays) can reach. This area, which spans the southern Atlantic and South America, is deepening and moving westwards. Could this be the beginning of the overdue magnetic field reversal?

The classical compass winds were named to reflect geographic direction as conceived of by the ancient Greeks and Romans. Ancient wind roses typically had twelve winds and thus twelve points of orientation. The Anemoi (from Greek “Winds”) were wind gods who were each ascribed a cardinal direction.

Supported by a professional practice and creative development bursary from a-n The Artists Information Company I have been privileged to have expert tuition in mould making and concrete casting from Anna Hughes based at Thames-side Studios. I have really enjoyed these sessions. Anna has given me the skills to go forward and experiment and I am excited by this new process. I prepared a dodecagon (twelve sided) shape cut in MDF to make a silicon mould and a double box mould for the base of my obelisk sculpture plus some small shapes for testing.

To continue the notion of sedimentary layers as signified by the layering of recycled paper in the body of the obelisk sculpture, I made collagraphs to line the box mould to give a texture of strata. Limestone, a sedimentary rock, is often formed from crushed seashells, compressed over eons. I used crushed oyster shells to use as aggregate for the base.

I am super pleased with how the base turned out.

I also tested using verdigris pigment mixed into the concrete or in the grooves of etched aluminium to leave an imprint. The plate tests didn’t come out so clear so need more testing and I next plan to try embedding the etched plate face up in the concrete.

Open Studios at Thames-side Studios 2023.

At a distance was installed in the main gallery group show. This work 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 (the first proposed Brexit date), 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.

In my studio there was recent magnetic work Pole Receptor, along with work in progress Belly of a Rock hybrid sculpture plus some works from the archive such as screen prints from the StrataGem and everydaymatters series. I spent the weekend preparing for my concrete casting tuition in between chatting to visitors. Thanks to Caroline AreskogJones for the studio portrait.

The StrataGem series of screenprints on textiles imagines the possibility of the formation of geological strata created from the waste of plastic food packaging trays.

Informed by the discovery that the matter we know, that which is visible to us and includes all the stars and galaxies is less than 5% of the content of the universe, dark matter making up about 27% and the remaining percentage being dark energy, everydaymatters dissects landscapes to discover the hidden structures of the universe. Images taken from everyday prosaic paradises, such as Paradise Industrial Estate in Hemel Hempstead, are split into constituent parts of what is seen and unseen.

Studio progress on The Azimuth Obelisk of Sedimentary Knowledge – all the paper is now torn down but lots still needs to have a hole drilled through to feed onto the frame. This sculpture is a response to the obelisk erected in 1955 at Hartland Magnetic Observatory, near the site’s northern boundary as a permanent azimuth mark viewed from the north facing window of the observing hut (also known as the absolute hut). I have been sorting out if I have enough old boards for the north wall of The Absolute Hut and have been donated some old monitors and screens to see if I can get them working to use inside. I am thinking of having several screens playing video in the hut – as in the brain – a sensory hub there are different activities and processing going on in different locations. More paper clay forms have been added to The Belly of a Rock sculpture framework to house the video screen – this hybrid sculpture is a place of chemical conversations at the intersection of the animate and inanimate.

Fabulous tech and plaster sculptures from Tessa Garland in Postcards From the Volcano at Thames-side Gallery.

Light Being curated by Jonathan Miles of The Wild Parlour at Lychee One.

We were talking of such things: shadows, obscure illumination, folds within substance, but all without a schema that would serve to cohere. Then someone interjected about the rootmeaning of the word for being human as being an entanglement of light, thinking, and being. This would then generate a sense, like something in the air, but also a generation of a spacing for work. Rather than being an exhibition with a theme, instead a tonal poetics and with it a letting be or presentation of an accord would emerge. – Jonathan Miles

Quantify

 “How do you calculate upon the unforeseen? It seems to be an art of recognizing the role of the unforeseen, of keeping your balance amid surprises, of collaborating with chance, of recognizing that there are some essential mysteries in the world and thereby a limit to calculation, to plan, to control.”  Rebecca Solnit, A Field Guide to Getting Lost

At Hartland Magnetic Observatory and other magnetic observatories around the world solar activity is examined daily and forecasts are given if this is likely to have any geomagnetic effect on Earth. The main geomagnetic field is also constantly changing due to convection flows and waves in the Earth’s core. As this change cannot be predicted, uncertainty slowly increases over time.

Most of my work at the moment is towards the exhibition A Stone Sky, with Julie F. Hill at Thames-side Studios Gallery later in the year. Very excited to be working alongside Julie and to have space to be ambitious in scale.

The Absolute Hut installation, reimagining the magnetic observatory room, will be a combination of planning to build the structure and unpredictability through processes used for the surfaces. Measuring for the north facing wall to be built in sections for easier transportation. Testing scale and coverage of field contour shapes cut in copper with a plasma gun.

I am hoping the north wall structure can be made up soon and the boards attached. I will then keep it outside facing north until the exhibition in an attempt to grow some moss on its surface. I have only had some very small success so far growing moss, despite trying a new culture recipe and being very diligent misting every morning and evening.

The topological contours of suminagashi marbling, which also echo fluid magnetic field lines, have inspired me to experiment with this idea for The Absolute Hut roofing. I have bought a sumi ink stick in whiteish green, an ink grinding stone and some verdigris pigment from Cornelissen in preparation to try this idea out. In this process the magnetic field lines appear embedded into the fabric of the hut that monitors (senses) the emanations from the Earth’s core.

Through the north facing window of The Absolute Hut, The Azimuth Obelisk (Obelisk of sedimentary knowledge) will be viewed. The sculpture is formed by tearing, drilling and layering sheets of paper. As sedimentary rocks build over time, so the obelisk has a lot of time invested in its making and conceals the history of past events in the hidden layers of the recycled prints and drawings.

I am still working on etching the Directional Magnetic Steel pieces. It can be a frustrating process as some batches work well and some do not etch well at all but come out dull and patchy and I’m not sure why. My idea was to use these pieces to draw a line across the gallery floor signifying the westward drift of the magnetic field from geographical north but now I am thinking more about mapping out a spiral shape in shaped pieces to echo the rotation of the Earth’s molten core.

All information about the Earth’s core has come from studying seismic data, analysis of meteorites, lab experiments with temperature and pressure, and computer modelling. Seismometers convert vibrations due to seismic waves into electrical signals. The velocity and frequency of seismic waves changes with pressure, temperature, and rock composition. The discovery that Earth has a liquid layer beneath the crust and a solid inner core has come from detailed analysis of the different types of waves that pass through the body of the Earth. Looking at the composition of meteorites, fragments of asteroids, formed about the same time, and from about the same material, as Earth provides clues to what minerals the core might contain. Diamond anvil cells are instruments used to recreate the pressure existing deep inside the planet by squeezing materials between two diamonds surfaces. A combination of this data is used to in complex computer modelling programs resulting in detailed animations of the geodynamo, a process powered by the convection of heat in the outer core along with the rotation of the planet.

Also a few more layers of papier mâché have been applied to the sculpture that will house a screen with video for the work Belly of a Rock.

Other work in the research stage looks at the first use of a magnetic compass, the cardinal points of navigation and the compass predecessor the wind rose.

In classical antiquity, a time stretching from Homer to the early middle ages, geographic orientation usually referred to landmarks or astral phenomena to determine direction. Eos meaning dawn, and Hesperus, evening were named for sunrise and sunset with north (arctos) being marked by the constellation Ursa Major and later the Pole Star. The winds also became associated with direction, and named in accordance with their qualities such as hot and humid or cold and dry. In Greek mythology Astraeus, the god of dusk, and Eos, the goddess of dawn, gave birth to many sons of the twilight including the Anemoi, the four gods of the winds, each ascribed a cardinal direction. Boreas being the god of the cold north wind,  Notus the god of the hot south wind, Eurus from the east and gentle Zephyrus from the west.

The number of points on a wind rose began with the four cardinal points which were added to and refined over time. The winds were often given names that referred to a particular locality from where they seem to blow, so different places came up with various local names. Aristotle designed an asymmetrical 10 point wind rose which was later refigured by Timosthenes who is credited with inventing the system of twelve winds and using this more for navigation than for “the study of things high in the air.“

Classical wind roses were eventually replaced by the modern compass rose during the middle ages.

The “Vatican table” is a marble Roman anemoscope dating from the 2nd or 3rd Century CE, held by the Vatican Museums. Usually an anemoscope would be topped with a weather vane. Divided into twelve equal sides, each one is inscribed with the names of the classical winds, both in Greek and in Latin. 

At a quantum scale, all matter is underpinned by uncertainty. My fascination with particle physics began from simply wondering what everything was made of when you looked really closely. I looked up ‘fundamental building blocks of the universe’ and was blown away by this mysterious other world, so far away in terms of scale I can comprehend, yet a part of me and everything I interact with.

Quanta is a discrete unit that cannot be divided. Quantum physics is the study of energy and matter at the most fundamental level. The chemical reactions in a birds eye that allow it to ‘see’ Earth’s magnetic field involves the quantum entanglement of radical pairs of electrons. These electrons are excited by light, particularly the blue of twilight.

Photography was the first available demonstration that light could indeed exert an action sufficient to cause changes in material bodies. William Henry Fox Talbot 

The subject of the photograph (the sun) has transcended the idea that a photograph is simple a representation of reality,  and has physically come through the lens and put it’s hand onto the final piece. Sunburn Chris McCaw

This month NASA announced a new planetary defence strategy to protect Earth from an asteroid impact. NASA’s Double Asteroid Redirection Test (DART) on 11th October 2022, changed the orbit of the Dimorphos Asteroid in the first full-scale demonstration of asteroid deflection technology.

This marks humanity’s first time purposely changing the motion of a celestial object.

“An asteroid impact with Earth has potential for catastrophic devastation, and it is also the only natural disaster humanity now has sufficient technology to completely prevent,” Lindley Johnson, NASA’s planetary defense officer. First any potential collision objects must be identified. This will be the job of the Near Earth Object Surveyor, along with ground-based optical telescope capabilities, to find the still undiscovered population of asteroids and comets that could impact our planet.

A magnetometer is being sent on an eight year journey to Jupiter. It was launched this month from Europe’s Spaceport in French Guiana.

ESA’s Jupiter Icy Moons Explorer (Juice) has magnetic and electric field sensors on the end of the magnetometer boom. The boom is folded in three parts and packed against the side of the spacecraft for launch. Once unfolded in space, the sensors will extend clear of the main body of the spacecraft, allowing very accurate measurements without magnetic interference from the spacecraft itself.

The boom’s instruments will measure Jupiter’s magnetic field, its interaction with the internal magnetic field of Ganymede, and will help study the subsurface oceans of the icy moons.

Ganymede is the only moon in the solar system known to have its own magnetic field. The magnetic field causes auroras, which are ribbons of glowing, hot, electrified gas, in regions circling the north and south poles of the moon. Because Ganymede is close to Jupiter, its magnetic field is embedded in, or lies within, Jupiter’s magnetic field.

The discovery of the moons orbiting Jupiter by Galileo Galilei in 1610 was the first time a moon was discovered orbiting a planet other than Earth. The discovery eventually led to the understanding that planets in our solar system orbit the Sun, instead of our solar system revolving around Earth.

Nothing truly exists – except in relation to other things. Carlo Rovelli

Work in progress.

Building the azimuth obelisk made from layered re-cycled paper. This sculpture is a response to the concrete obelisk erected in 1955 at Hartland Magnetic Observatory as a permanent azimuth mark from which to measure the drift of Earth’s magnetic field. Deep time geology holds the sedimentary knowledge of magnetic activity, from the degrees of variation between the magnetic and geographic north pole to the cataclysmic impact of pole reversals.

Magnetism embodies magical qualities which have fascinated humans since the first encounter with a lodestone. These rare and enigmatic fragments found scattered across the surface of the Earth are created when lightning chances to strike the mineral magnetite.

The Lodestone, from Plato to Kircher by D. W. Emerson lists various historical references to the lodestone. The writer concludes – Lodestone, being very unusual, greatly impressed previous generations. Despite its unattractive appearance it was an admired mineral type more precious than pearls, it was celebrated in persuasive Latin hexameters, it was an analogue for the power of deities, it took a witch to subdue it, it was deemed explicable by Epicurean atomic theory, it was involved in a rather tenuous argument for eternal punishment of wicked persons, it meant doom for unwary mariners, it furnished fodder for folk lore, it resided in the arsenal of the apothecary, it helped to demonstrate the earth’s magnetism, and it assisted navigation. What other mineral has such a record? The lodestone was quite a remarkable rock; it still is, and oddly, yet to be completely studied and documented.

Pliny the Elder (AD 23/24 – 79) :

What is more amazing (than this stone) or at least where
has nature shown greater devilry? She gave rocks a voice
answering, or rather answering back, to man. What is more
indolent than the inert character of stone? Yet nature has
endowed it with awareness and hooking hands. What is
more unyielding than the harshness of iron? On it nature
has bestowed feet and a mode of behaviour. For it is drawn
by the lodestone, and the all-subduing substance hastens to
something like a vacuum, and on its approach it leaps
towards the stone, is held and kept there by its embrace.

Claudius Claudianus (AD fl. 395):

There exists a stone called lodestone; discoloured, dingy,
nondescript. It does not lend distinction to the combed
locks of kings, nor to the fair necks of girls, nor does it
gleam on the showy clasps of sword belts. But in fact if
you pay due regard to the strange marvels of this dark rock
then it outshines elegant adornments and anything, on far
eastern shores, that the Indian looks for in the weed of the
Red Sea (i.e. pearls).

Augustine of Hippo (AD 354-430):

We recognise in the lodestone an extraordinary ability to
seize iron; I was much perturbed when I first saw it. The
reason is that I clearly saw an iron ring grabbed and held
up by the stone. … Who would not be amazed at this power
of the stone?

Generating a magnetic field.

The dynamo theory states that to generate a magnetic field, a body must rotate and have a fluid core with an internal energy supply that is able to conduct electricity and drive convection.  Earth fulfils all of these requirements. It rotates faster at the Equator than it does at the poles causing spiral convection currents in the liquid iron outer core which is an excellent electrical conductor, powered by the energy released as droplets of liquid iron in the outer core freeze onto the solid inner core.

Any variations in rotation, conductivity, and heat impact the magnetic field created.

Mars has a weak magnetic field as it has a totally solid core. Venus also has a weak magnetic field for although it has a liquid core it rotates too slowly to create convection currents.  Jupiter has the strongest magnetic field in the solar system, with a metallic liquid hydrogen core and fast rotation, it has a magnetosphere so large it begins to deflect the solar wind almost 3 million kilometres from its surface.

The quote “sunlit uplands” has been used as political ideology, as an assurance for better days to come most recently the phrase has been linked to the promises of Brexit, with politicians leaning on this rallying rhetoric.

George Henry Longly Microgravities at Nicoletti. I found the slick production values, very shiny like outsize circuit boards of these works exposing sci-fi cliché and subverting popular space movie tropes sat very close to the ideas they are parodying. Microgravity – ‘the condition in which people or objects appear to be weightless’, according to NASA’s website – is responsible for metabolic and behavioural changes for space travelers. Some interesting theory behind this show about the human cost of living in space as our gut microbiome reacts to a weightless environment. I liked the reflection cast on the floor from the mirrored circle left exposed as a planet on the widescreen landscape.

While certain works function as indexes of failed attempts at control, others recognise the perceived failure of the human body, positing that from a spiritual perspective: if perfection is nonexistent, then failure is all we have, all that is real. One or two of the hanging pieces are reminiscent of the votive offerings at holy wells or the love lock bridges festooned with padlocks.

Bridget Smith Field Recordings at Frith Street Gallery. Natural material processes, simply presented. The weathering of bulrushes, the materiality of analogue photographic techniques such as ambrotypes and tintypes, the simplicity of a moon rising over the sea.

Daniel Shanken The Cascades at Stanley Picker Gallery. I was excited to see this show as the randomness within the work is derived from radioactive decay and I thought the title may refer to cascades of comic particles but perhaps it refers to cascades of data. The aesthetic was very game based and the randomness not explicit in origin. I liked the set up though with the projection onto the floor creating an abyss to gaze down into from an industrial style walkway.

David Blandy Atomic Light at John Hansard Gallery Southampton. Four films circumnavigating the fallout from the atomic bomb massacre at Hiroshima. The body of work is inspired by a family history, a grandfather, a prisoner of war in Singapore – held by the Japanese but felt himself saved by the detonation at Hiroshima. The golden hour light is so perfectly captured and reflected in The Edge of Forever which gives voice to the children, accusing, watchful and alone. This was filmed by his partner and features his own children. Soil, Sinew and Bone is a collaged documentary of archival material, mirrored so that the central area of the film takes on the shape of an a atomic bomb. In Sunspot two scientists, one in Japan, one at Mount Wilson Observatory are monitoring the activity of sunspots, the flares that can erupt and disrupt radio signals as the particle filled solar wind and magnetic turbulence blasts across the magnetosphere. The film Empire of the Swamp has a wonderful rich narration embodied in the voice of an ancient crocodile who remembers the mangrove swamps before the war and the arrival of the white man.

I enjoyed the Art Fictions podcast with guest Jennifer Higgie discussing her writing practice via the 2009 novel Drive Your Plow Over the Bones of the Dead by Olga Tokarczuk. I was then lucky to see Complicitie’s excellent interpretation of this novel on stage at the Barbican directed by Simon McBurney.

‘this is a tale about the cosmos, poetry, and the limitations and possibilities of activism.‘

Complicitie’s production employed the same blinding flash technique as Alfredo Jaar used in his work The Sound of Silence which I saw in 2006 and still remember vividly. Sitting in a dark space a story of one photograph, taken in Sudan 1993, is told in simple sentences on a large black screen. The photograph is shown momentarily before a blinding flash of light scores the retina. You are left blinking in the afterglow. The image won a Pulitzer Prize, but the South African photographer Kevin Carter committed suicide at 33 after struggling to come to terms with what he witnessed, and the public response for not having intervened to save the child’s life. In the novel Drive Your Plow Over the Bones of the Dead, Janina, the eccentric ‘older woman’ does not hold back from intervening when she sees injustice to any living thing. She is also vilified, but for showing compassion for the animals.

Alfredo Jaar 'The Sound of Silence'

I also dredged up the memory of having seen the film Spoor at the 2017 BFI LLF also based on this novel. Finally I have bought a copy of the novel. A circuitous route to the original text.

I am very much enjoying reading Rebecca Solnit A Field Guide to Getting Lost. Her writing is like a torchlight illuminating one idea after another, sweeping across a multitude of topics with an infectious energy to explore and experience the unknown.

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.

Reading

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.

Listening

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.

Super happy with the beautiful box, with walnut burr veneer, made by the skilled hands of Bruce Watson to house my cosmic ray detectors for cosmically interactive work The Breath of Stars. Bruce has a workshop opposite my studio at Thames-side Studios. The attention to detail is immaculate.

The Breath of Stars is a digital video work activated in real time by the passage of cosmic particles travelling from distant galaxies. These subatomic visitors from outer space are created during super nova explosions or by phenomena we are yet to discover.

Work in progress continues with tearing down paper squares for the Azimuth Obelisk.

Single vertical forms embody a primitive power. Etymologically, an obelisk should be made from a single quarried stone. To quarry one enormous piece of rock without it fracturing required power and money. To erect it required complex engineering skills. Since the first obelisks were raised in Egypt, often in gateway pairs with gilded tips for the sun god Re to anoint, they have escaped the confines of their original meaning. Originally a motif of immortality and communion between heaven and earth, its phallic symbolism has been co-opted by many nations, institutions and companies for its crude assertion of male power. Mystics shape crystals into obelisks as symbols of pent up negative energy in need of release. Perhaps the many memorials to the dead, marked by an obelisk usually cast in concrete, attempt to embrace the notion of immortality through remembrance in those carved names.

I don’t know why an obelisk was chosen as the azimuth marker at Hartland Magnetic Observatory. It’s hard to establish its actual shape as it can barely be seen now through the woods. Perhaps one day I will go back with binoculars.

I have imagined my obelisk sculpture as sedimentary rock with the layers holding clues to the fluctuations of the Earth’s magnetic field it stands as constant sentinel to. Made from recycled prints it is also a memorial to all the images buried in its form.

Looking North.

After unsuccessfully trying RHS Wisley for a book or advice on growing moss I have got some guides from the Field Studies Council. Hopefully these will help me choose the sort of moss that will be appropriate to use for the north wall of the Absolute Hut Installation. I am also beginning to collect wood to grow the moss on. The exhibition is several months away but I think it can take a while for moss to get established. The advice seems to be to liquidise some moss with yoghurt and spread it on the surface you want it to grow on.

The geographic north pole lies in the middle of the Arctic Ocean covered in shifting sea ice where the sun rises and sets only once per year. All lines of longitude converge here and hence all time zones. It is known as true north to distinguish it from the magnetic north pole.

However, as the Earth’s axis of rotation wobbles slightly in an irregular circle called the Chandler wobble this pole is not fixed. Where Earth’s rotational axis meets its surface is known as the instantaneous north pole and the north pole of balance, lies at the centre of this circle. The celestial north pole is where the axis line of the Earth extends into the night sky.

The magnetic north pole is where the planet’s magnetic field is vertical and a compass needle here would dip and try to point straight down – hence its other name: the magnetic dip pole.

The north geomagnetic pole is the northern dipole of the planet. When looked at from space the Earth may look like a bar magnet with two dipoles, but the geomagnetic poles are an approximation arrived at by reducing Earth’s complex and varied magnetic field to that of a simple bar magnet. The north dip pole lies in Northern Canada, the northern dipole is roughly off the northwest coast of Greenland.

The magnetic field lines of the Earth flow from south to north magnetic pole which is the opposite of a bar magnet where the lines flow north to south.  The north magnetic dip pole is where the earth’s magnetic field lines pull toward the planet, acting like the south pole of a bar magnet. The north pole of a bar magnet is attracted to the magnetic north pole of the Earth, not resisted as two north poles on magnets repel one another.

The extraordinary paintings in the Lascaux Caves of southwestern France may include representations of constellations and therefore be the earliest star maps dating back to nearly twenty thousand years ago. The dots set around an Aurochs eye in the Hall of Bulls may be the Hyades star cluster around the star Aldebaran as the eye of Taurus. Other dots are similar in configuration to the Pleiades. Now sealed off from the contamination of human breath the public can visit a replica site to gain a sensory experience of the scale and artistry. Painted on to the wall of the shaft is a bull, a strange bird-man and a mysterious bird on a stick. which according to Dr Rappenglueck, form a map of the sky with the eyes of the bull, birdman and bird representing the three prominent stars Vega, Deneb and Altair. Around 17,000 years ago, this region of sky would never have set below the horizon and would have been especially prominent at the start of spring.

The Pleiades visible to the naked eye from almost anywhere on Earth appear as a small asterism of six or seven stars. At a distance of about 444 light years, it is among the nearest star clusters to Earth. Chased by Orion the seven sisters were transformed by Zeus and flung into the sky to escape the hunter. Through a lens, we can now see there are a lot more sisters drifting through a cloud of interstellar dust which scatters the light into a misty blue cloak. Image by Emil Ivanov.

A third research trip to Snettisham.

This time I shared the experience with good friends Ruth and Odile and we joined an RSPB group visit which allowed parking nearer the viewing site avoiding the usual long walk in the dark. The drive along the narrow potholed track, with no headlights which would alarm the birds, is a challenge and I was grateful for another car who had visited before leading the way. It was a chilling -7 at 7am making it difficult to use the camera with frozen fingers.

Eventually the sun cut through the low mist giving us stunningly beautiful skies to watch the skeins of pink footed geese leave their roost to go in search of sugar beet fields.

Having spent the night on the mudflats to avoid predators they leave at dawn in family groups. If there is a bright moon shining, they might not return from the feeding grounds at night as they can see if there is any danger approaching.

Before leaving Norfolk we visited Welney Wetland Centre, Britain’s largest area of seasonally-flooded land and the setting for mass winter gatherings of many thousands of wild ducks, geese and swans. Each winter thousands of Bewick’s and whooper swans make their winter migration to the UK, to escape colder countries.

They have popular swan feeding sessions and talks about the site and the work they do to protect the wildlife here such as liaising with the electric companies to hang reflectors on the overhead cables to make them more visible to flying birds.

Walking around the frozen fens reminded me of the James Turrell installations of diffuse light that makes it hard for the eye to focus.

The light-sensitive molecules that allow perception of the Earth’s magnetic field, could also influence other responses such as control of circadian rhythms and tracking the difference between night and day. In birds, Cryptochrome molecules are located in photoreceptors in the eye and react to the Earth’s magnetic field when excited by blue light enabling orientation and navigation. Light sensitive molecules can also be found in cell nuclei and may influence physiological processes, such as fattening and migratory motivation, working as a trigger for changes in behaviour.

Light vibrates up and down as it travels in waves and these vibrations can be vertical, horizontal, or at any angle in between. The waves that make up sunlight are evenly distributed across all angles but polarised light is made up of waves with the vibrations at only one angle. Polarising lenses absorb horizontal light while letting through the vertical waves reducing the overall intensity of the light that passes through. Light also becomes partially polarized when it reflects at an angle from a surface such as when the sun is low in the sky. Research led by Rachel Muheim has shown that birds are better able to use their magnetic compass when the direction of polarised light exciting the cryptochrome molecules is parallel to the magnetic field. She suggests that it is more useful for birds to sense the magnetic field during sunrise and sunset for orientation to determine their direction before migrating or leaving the roost. In the middle of the day, when the polarised light is approximately perpendicular to the magnetic field, it can be an advantage that the magnetic field is less visible, so that it does not interfere at a time when visibility is important to locate food and to detect predators.

Abraham Kritzman A Hand Beneath The Hills at Danielle Arnaud. I was intrigued to visit to see the small pillar structures and the interesting use of ceramics. Kritzman doesn’t like to give a lot away about his work so impressions are not pre-directed. The camouflage paintwork on the sculptures, crenellations and frenetic lines in the prints had a war like ambience. The influences however appear to come from the insect world of metamorphism, burrowing and speed.

Reading

Being a Human by Charles Foster. I got this book as I thought it might offer some points for discussion at the upcoming debate Being Human in relation to the night sky to be held at Allenheads Contemporary Arts. Unfortunately it didn’t have any useful insights and was rather judgemental and smug despite some clever and comic attempts at self effacement. The sort of smugness that emanates from those of devout faith where the judgement is on those unfortunate enough not to share or even aspire to the same definitive experience as that of the author. It also has some of the smugness of the parent loudly interacting with their offspring in public to show off their parenting skills/precocious/cute child. I did appreciate it was well written and researched. Acres of endnotes and a huge reading list which could turn out to be useful. Some points were well made about the edge as the site of all change and the idea that what is imagined is no less real but the packaging just wasn’t for me.
