Work in progress on the Azimuth Obelisk sculpture has taken a new direction and I have abandoned the idea of casting the obelisk in aerated concrete. I also have new dimensions to work with having found an interesting article on the historic dimensions of obelisks with the advice that ‘designs that have too large a gap in scaling between elements will lack hierarchical cooperation and lead to a sense of emotional unrest‘.

Looking at layering of sedimentary rock holding memory of magnetic field information I am aiming to make the sculpture from layered paper to echo the effect of strata, using unwanted old work on paper as well as other paper that would otherwise be discarded. It has been satisfying tearing down old prints that were languishing in plan chests and old work from foundation courses and art classes. It even has an obelisk within the obelisk. I am collecting donations from everyone I know who works with paper as I have estimated I need about 8,000 sheets to reach a height of over 2m.

Work in progress on The Breath of Stars cosmic ray interactive work is still pending. After spending hours formatting and loading the raspberry pi with the video files of cosmic trail starbursts I heard from Jamie the programmer that .avi files are not going to work and these might need converting to WebM files which might not be easy. Hoping to find a solution to this soon.

Great fun greenscreen filming slime for Belly of a Rock – a video sculpture partly inspired by the Cosmicomics story The Spiral and partly inspired by paleomagnetism where magnetic minerals in rocks can archive a record of the direction and intensity of the magnetic field when they form.

“I began to give off excretions which took on a curving shape all around” The Spiral, Italo Calvino

“..I accompanied the effort of making the shell with the effort of thinking I was making something, that is anything: that is, I thought of all the things it would be possible to make. So it wasn’t even a monotonous task, because the effort of thinking which accompanied it spread towards countless types of thoughts which spread, each one, towards countless types of actions that might each serve to make countless things, and making each of these things was implicit in making the shell grow, turn after turn…” Italo Calvino The Spiral

Fabulous shells lent to me by my neighbour for spiralling inspiration. The size of them not easily appreciated in these images. They are huge. I have no idea how old the molluscs that made these could be.

Other work in progress is towards using the small monitors bought as a good deal on eBay set in a circle displaying video dissected into twelfths. Testing ideas with kaleidoscopic images from soap bubble videos and relying on technical help from next door getting the monitors to work

Delighted to be invited to join Sandra Crisp and Jockel Liess for an exciting moving image event. Each artist has a unique approach to film incorporating the study of form, surface and location. DM for an invitation.

Sandra Crisp: E_Life uses 3D generated animation to present a digital environment populated with intensely textured and dynamic geometry.

Jockel Liess: Variations on a theme is a generative audiovisual system which starts from a point of fascination with the aesthetics of irregular organic patterns.

My work Aóratos (new edit for this event) transports the viewer between everyday locations and terrains visually transformed via the use of an endoscope, a microscope, and cameras launched in a high-altitude balloon.

Paused to see the wonderful World Time Linear Clock at Piccadilly Circus Underground Station built in the early1920s and recently refurbished.

The band of roman numerals scrolls West at the same relative speed as the earth rotates, completing a circuit in 24 hours.

“The clock by which we measure time on our watches and digital devices is very misleading; it is determined by the daily rotation of the Earth around its axis and its annual rotation around the sun. This astronomical time is linear and regular. But the actual clock by which we live our socioeconomic lives is an emergent phenomenon determined by the collective forces of social interaction: it is continually and systematically speeding up relative to objective astronomical time.”    Geoffrey West

I also did a little research to find out more about the Azimuth Mirror I was given as a present. An azimuth mirror is used for taking the bearings of terrestrial and celestial objects. An azimuth is defined, from any given observation point, as the angle between an object or point and a reference line, usually to true North, moving away from that reference line in a clockwise direction on a horizontal plane. Through the use of mirrors, lenses and prisms, the instrument allows both, the readings of the compass card, and the object to be seen at the same time and in the same direction. It is portable equipment which is placed over a magnetic or gyro compass to aid navigation using either a landmark, when the arrows would be pointed down, or from a celestial object when the arrow would be pointed up. The little glass circle was once a spirit level but that has dried up. The word azimuth is used in all European languages today, it originates from medieval Arabic meaning “the directions”.

Finally made it to meet the Go Stargazing Walton Astronomy Group at their monthly session. We found them on the green at Esher which has been recently over illuminated with bright LED streetlights by a thoughtless council ruining the skies for astronomical observation and disorientating local wildlife and plant life. The local MP Dominic Raab IS NOT A MEMBER of the All Party Parliamentary Group for Dark Skies. Click on the link and ask your MP to join in protecting our dark skies.

When we look up to the heavens, we largely see the same view that captivated and inspired our ancestors. The constellations, the Milky Way, shooting stars, and the night sky are woven into the fabric of our society, cultures and religions. The night sky is one of the most inspirational views that our planet offers.

We are on the precipice of losing the night sky. Right now, SpaceX and other companies are planning to launch tens of thousands of bright satellites in orbit around the Earth.

There is an Avaaz petition at this link urging protection of the night skies.

Bringing back memories of the 2015 Nelly Ben Hayoun film Disaster Playground

….NASA celebrates a Smashing Success – A team of researchers confirmed that the DART spacecraft’s impact with Dimorphos successfully altered the moonlet’s orbit around its parent asteroid by 32 minutes – marking the first time humans have changed the trajectory of a celestial object in space.

To me this feels like a major historical event. What has this little nudge set in motion?

Exhibition visits

Expanded film at the BFI London Film festival.

Framerate: Pulse of the Earth by ScanLAB Projects presents Destruction, extraction, habitation, construction, harvests, growth and erosion are presented as a shared immersive experience. The 3D time-lapse scans of British landscapes observe change on a scale impossible to see with traditional filmmaking techniques.

One of my favourites was Monoliths by Lucy Hammond, Hannah Davies, Asma Elbadawi and Carmen Marcus – we are shaped by the spaces that made us. Through footage shot in the north of England and personal narrative the women embody three monoliths – standing stones, whose symbolic power becomes increasingly important as the women talk.

Elizabeth Murton and Jane Glynn, explore the dynamics of time and movement in Fluid Time at The WaterMill, Mill Green Museum, Hatfield with live dance performance of Elizabeth Murton’s The Giant Weave from BEEE Creative full of joy and energy.

Libby Heaney in remiQXing still at Fiumano Clase. A solo presentation of video and physical works exploring the emerging field of quantum computing as both a subject and medium, turning the gallery space into the showroom of her fictional quantum computing company QX (Quantum eXperience). Some fabulous super shiny prints on mirrored dibond and ethereal prints direct to media on clear acrylic.

Transports of Delight at Danielle Arnaud curated by Edward Chell. In the 1830s, East London doctor and amateur naturalist Dr Nathaniel Bagshaw Ward invented a sealed glass case, an ecosphere in which plants could survive heavily polluted air. Named after its inventor the Wardian case enabled the transport of plants by sea around the world and transformed global economies and environments, shaping the world we live in. Exhibition includes works by

Anna Barriball | Daphne Wright | David Cotterrell | Edward Chell | Gerard Ortín Castellví | Günther Herbst | Harun Morrison | Helen Maurer | Joseph Banks | Joy Gregory | Laure Prouvost | Lee Maelzer | Leelou Gordon-Fox | Maria Thereza Alves | Mariele Neudecker | Nick Laessing | Nils Norman | Owen Griffiths | Peter Hofer | Pia Östlund | Rosa Nguyen | Stephen Lee | Uriel Orlow |

ABSURD at OHSH Projects exploring the absurdity and strange rituals of our daily lives, the bizarreness of
which are brought to light when taken out of context. The institutions, structures and traditions we have built around ourselves and imbued with power and importance can highlight this most starkly; through religion, schooling, government, work and even our own homes. Curated by Henry Hussey and Sophia Olver. Exhibition includes works by Gillies Adamson Semple, Samuel Bassett, Jonny Briggs, Tom Bull, Ladina Clement, Janina Frye, Johnny Hogland, Mark Jackson, Lea Rose Kara, James Lomax, Hynek Martinec, Rasmus Nosstring and Lottie Stoddart.

Hypha Studios presents a showcase of some previously selected artists at the project space on Conduit Street. Hypha Studios matches artists with empty spaces across the UK. Artworks include those by Beverley Duckworth, Foka Wolf, Dion Kitson, Futures After and Josh Wright’s “Lost in a Just In time Supply Chain”, Anna Fearon, Tom Skipp, Molly Stredwick, Gabriela Pelczarska, Salvatore Pione.

Subatomic at The Science Gallery is a project by composer Christo Squier and experimental particle physicist Dr. Teppei Katori that looks at ways of interacting with cosmic rays, something I have been working on myself in the work The Breath of Stars for the last year or so. I was equally excited and anxious to see what they were presenting. They have created a particle shrine which takes data from the Super-Kamiokande observatory in Japan as well as live data from cosmic ray detectors to create a light and sound experience with vibrating mirrors. Rather jealous of the technical resources this project had access to.

There was also a performance of live music by a small orchestra responding in real time to data from the Super-Kamiokande observatory and compositions inspired by cosmic ray observation data.

A lot of the data used in the music responses and the particle shrine is publicly available data from the Super-Kamiokande observatory in Japan. I did notice that the cosmic watch detectors hooked up to the particle shrine are not set in coincidence mode to be sure it is cosmic particles that are being recorded. A lot of what Christo said during his presentation echoed how I feel about cosmic rays, the fact that they come from other galaxies and pass through us making that physical connection with outer space.

Sanctuary at The Swiss Church takes inspiration from the disparate and striking surrounding architecture, and the stories of people within the Covent Garden community, artists Ali Clarke and Gary Scholes have created a series of structures that symbolise individual sanctuaries. Amazing detail in some of the constructions, especially impressed with the scaffolding bolts.

Reading

Came across some great finds at the local Oxfam bookshop on mapping and magnetism and time, all interconnected.

I read Conquest of the Useless as I thought it might be relevant to research on exploration of the unknown. It was definitely a worthwhile read portraying the total dedication to following through a dream, the power of the creative urge. Watched the film Fitzcarraldo afterwards which although extraordinary doesn’t convey the true life drama and hardship recorded in the book experienced by the actors and film crew in telling the story.

Listening

Sensory overload on the Lizard Point Artist Residency hosted by Mayes Creative and Lumen London. Serpentine rocks, wide horizons, sparkling sea, dark starry skies swept by the dazzling beam of Lizard Lighthouse.

We are here to research the communication heritage of this dramatic coastline once plagued by shipwrecks and pirates.

Rachel Holder from the National Trust guided us along the cliff path and told stories of the treacherous seas and lives lost on the hidden rocks. We heard about the history of Lizard Lighthouse and other methods of communication across distances.

We visited Marconi’s radio station hut which was full of wonderful scientific equipment like spark transmitters and Morse code machines. In the early 1890s, Marconi began working on the transmission of telegraph messages without connecting wires. An early experiment was a storm alarm made up of a battery, a coherer (an early form of radio detector consisting of a glass tube loosely filled with metal filings whose bulk electrical resistance decreased in the presence of radio waves), and an electric bell, which went off when it picked up the radio waves generated by lightning.

The message ‘WE ARE ONE’ was filmed on 29th March {non} Brexit Day signing with entanglement semaphore flags across the ocean

The plan is to make a film exploring communication across distances, relating it to entanglement theory where two paired electrons mirror each other. This will then be back projected onto a frosted Fresnel lens as used by lighthouses.

Joanna Mayes gave us a warm welcome to Cornwall on arrival as we witnessed the molten sun colour the whole sky before dropping out of sight.

1903 sunset

Sitting in the receding warm glow of the sunset we listened to the electromagnetic musical collaboration between sound artist Justin Wiggan and some house plants.

The Sky Disc of Nebra is a Bronze-age astronomical disc possibly used to determine the seasons for sowing and harvesting in the Halle area of Saxony-Anhalt, Germany. It is the oldest depiction of the cosmos yet known from anywhere in the world. It was discovered in 1999 by metal detectorists working illegally who sold it onto the black market where  it was later recovered in a police sting operation. Analysis shows the gold and tin used in the disk were from the Carnon Valley in Cornwall. Evidence of ancient links between communities.

Digital StillCamera

Workshops during the residency included looking at found matter under the microscope

A Chemigram workshop which involves painting various resist materials such as toothpaste, suncream and honey onto photographic paper before exposing to sunlight, fixing and developing.


Astrophotography; learning the camera settings to use to capture the extraordinarily starry night sky we were fortunate to experience. This shot was using bulb mode, focus infinity, 2.8 aperture, 3200 ISO, 30 sec exposure.

We did have to try and escape the sweeping beam of the Lizard Lighthouse but for some shots the added exposure gave some interesting results.

On the trip down to join the art and science Lizard Point artist residency we found ourselves serendipitously having a delicious afternoon tea at The Cornubian Arts & Science Trust (CAST)

The original Science and Art School was built in 1897 by Cornish philanthropist John Passmore Edwards at the request of local people.

The disperse papers left over from making the entanglement semaphore flags have good wormhole portal potential

Two great resources discovered:

Design Me print studio where I have tracked down a large format heat press available for open access.

Fat Llama a rental resource for practically anything and everything.

I rented an EF 100 f2.8 USM macro lens and set up a mini green screen in the studio. Apparently black tourmaline is good at cleansing negative energy so I sourced a pendant to use to create a hypnotic state of relaxation encouraging the release of negative energy to power the transformation wormhole. Have changed the chain to leather thong.

Not sure what the backdrop will be yet. Also tested the movement of iron filings against the green screen.

I made a frozen ice disk and tested back projecting particle trails onto it. This was tricky to film as rather slippy but I can see this could be a good effect showing the detail in the ice.

1903 projections on ice

Cosmic rays stain icey asteroids red.

Tested filming the cloud chamber with the macro lens and although the depth of field maybe better because it’s such a small area in the viewfinder I didn’t capture many trails.

1903 particle trail 5

I’m not sure the result was better.

1903 particle trail 3

Got some good air turbulence though

I made a site visit in heavy rain to Salisbury Arts Centre

I will be installing Pentacoronae hanging sculpture for the Insatiable Mind exhibition as part of Salisbury International Festival.

1809 Pentacoronae

It was great to meet everyone and hear about their ambitions for the space. Being an old Church the ceilings are very high. It’s going to be a challenge but they do have their own cherrypicker.

In preparation for the launch of the high altitude balloon with a cloud chamber in the payload students from Imperial College Space Society experimented with the mini DIY Cloud Chamber kits I provided.

1903 testing mini chamber 2

They are testing outcomes to design a prototype chamber that can withstand low pressure at high altitude, also they must ensure the base plate is kept extremely cold to create the supersaturated environment but any batteries onboard are kept warm enough to function and that turbulence doesn’t cause a whirlpool effect in the cloud.

1903 testing mini chamber 1

It looks like we might be launching from an airfield near Oxford.

The New Materialisms Reading Group I attend are currently reading Scale. Geoffrey West’s research centres on a quest to find unifying principles and patterns connecting everything, from cells and ecosystems to cities, social networks and businesses. Full of interesting facts about heartbeats and energy, lifespans and growth cycles.

1903 tree rings

It has been alarming to read about the terrifying unpredictable phenomenon of exponential growth. At the beginning growth is slow, but this soon accelerates to such a rate that it becomes out of control, unstoppable and then collapses under its own weight.

I am also still trying to understand entropy as explained by Carlo Rovelli in The Order of Time. So, the universe began with low entropy and it has been increasing ever since, the past leaves traces in the present caused by the irreversible process of energy degrading into heat from which our brains create extensive maps of past events and this is what gives us the sensation of time passing.

Out of Studio

A packed gallery for Ray Richardson‘s entertaining talk and screening of award winning Our Side of the Water at Thames-side Studios shows how much he is held in our mutual esteem.

Fun night with Andy Holden at The Cinema Museum.

1903 Andy Holden Cinema Museum

Laws of Motion in a Cartoon Landscape uses live green screen filming allowing the narrator to interact with clips from hundreds of cartoons. The film proposes the world is best understood as a cartoon through examining the formation of ‘laws’ within cartoons as a way of making sense of the world we inhabit, a space where anything could potentially happen.

I joined some students from Imperial College Space Society and other High Altitude Balloon enthusiasts at Wormwood Scrubs for the launch of a couple of Pico balloons that they are testing tracking with the aim of making a complete circuit of Earth.

1903 pico launch 1

Anxious moments as the balloon barely gains height but soon it has vanished from sight

1903 pico launch

The next couple of hours are spent listening in for the tracker system transmissions which can drop in and out of range; travelling at something like 60metres/second both balloons made it to Belgium before the transmissions ceased.

1903 pico launch 2

Work resulting from an unexpected encounter that demands attention in By The Way at Lewisham Art House had some ephemeral photopolymer etchings of found seashore plastic by Sam Hodge.

1903 Sam Hodge.jpg

I also liked this work by Mark Sowden who photographed found frames and then mounts the resulting image in the frame.

1903 Mark Sowden.jpg

Great show Undertow at Sluice HQ. When prevailing discourses tip towards hyperbole, generalisations or simplification, there is a need to swim against the current, to carve out a space that allows for ambiguity, correspondence and a quieter voice. In the employment of few words, a scale of action or use of minimal materials, understatement can be both a way of confronting moments of crisis, or of evading them.

Time Tries All Things video installation at the Institute of Physics by Grace Weir explored time and our human relationship with it.

1903 Grace Weir Time Tries All Things

Two narrators consider time from different perspectives against the backdrop of a stone carver replicating a plaque, repeating time.

DAVID:
I think when people talk about time they often confuse two sorts of thing.
There is time itself and there is what’s called the arrow of time, which is
direction, and its perceived nature as a human being.

FAY:
Being or becoming is an ancient question.
Ever since we have records of people thinking about the world, in ancient
Greek philosophy for example, there have been people on both sides of
this debate.

The complete audio transcript is available here.

There is a very impressive diffusion Cloud Chamber in the foyer at The Institute of Physics. Lots of activity but it was hard to see the particle trails clearly through all the reflections. 1903 Diffusion cloud chamber

They also have a cosmic ray detector on the roof which has scintillator plates containing molecules of a substance which emit a tiny flash of light when they are hit by a high-energy particle.
