Work underway for the upcoming Reading Stones exhibition with artists Anne Krinsky and Carol Wyss. We will be installing site-specific works in response to the history and architecture of the ancient stone Tower of Saint Augustine, Hackney’s oldest building. Built in the 13th century, the tower houses a magnificent 16th century clock whose mechanisms still strike the hours, occupying three floors connected by steep spiral stone stairs.

1908 clock.jpg

The nature of time itself was a concept that St Augustine of Hippo grappled with in his philosophical texts sixteen centuries ago and is still perplexing us today; namely, how to equate the subjective experience of time with an objective understanding.

I am working on a video which makes reference to the scientific theory of time crystals; a model which proposes a structure that repeats in time, as well as in space.

1908 Time Crystal 2 wip

Patterns used in the film aim to mirror the crystal structure of the mineral beryl, commonly used to fashion the original reading stones which were used to magnify texts before the invention of optical glass. Reading Stones could be considered the first instruments used to create an enhanced sensory experience.

I am playing with speeding up, slowing down and overlapping events to deconstruct a linear flow of time and interrogate the methods used to measure and experience time. I  spent a couple of nights in remote car parks setting up a time lapse sequence under darkish skies in anticipation of  the Perseids Meteor Shower and was rewarded with my first experience of live meteor action.

1908 perseids

I also think there was a faint glimmer of the Milky Way. These weren’t true dark sky areas but not bad for an hour to two hour drive from London.

1908 milky way

Also set up a time lapse station overnight on the Suffolk coast with the two wind turbine’s in view that dominate the Kessingland village skyline. I was surprised to see how much aerial activity goes on usually unnoticed.

1908 wind turbines

Another times lapse experiment focused on crystal growing over a week period.

A site visit to St. Augustine’s Tower gave me pause for thought over the hanging sculpture I had planned which would possibly be dangerous to attempt. So looking at projecting directly onto the brickwork in that corner instead. This is giving me all sorts of issues over projecting in portrait mode and whether the projector will cope being on its side.

Testing ideas for a viewing circle on the tower roof.

1908 viewing circle test

Inside the circle will be the image of a rock or meteorite.

I have been auditioning candidates.

On the final day of the exhibition we will have extra activities which will include a lithomancy board and the chance to have your fortune told by the fall of the stones.

The act of “reading stones” can refer to both the scientific practice of geological investigation and the ritual of lithomancy which seeks to interpret the patterns of stones cast by those wishing to divine the future.

Made a trip to Box Hill Fort for a photo shoot of the artists books I had made for the Insatiable Mind Exhibition. The Fort is one of a line of 13 mobilisation centres built in the 1890’s to protect London from the threat of invasion from continental Europe. Never used for its intended purpose, it is now part of the National Trust Box Hill property and home to three species of bats that have taken up residence in the tunnels originally built for ammunition storage.

1908 unbound detail

‘Unbound’ depicts images taken from my cloud chamber. A cloud chamber is a supersaturated sealed environment that enables us to see the trails of cosmic rays. These high energy particles know no boundaries, travel at high speed across the universe and continuously pass unseen through us and our world. The twelve pentagons form a dodecahedron, the solid described by Plato as ‘the fifth construction, which the god used for embroidering the constellations on the whole heaven.’

1908 unbound

1908 InOUT detail

‘In/Out’ expresses the energy and randomness of quantum fluctuation as particles pop in-and-out of existence in empty space. At this tiny scale the universe is mysterious and unpredictable. Originating from a large crystal ball which reflects and absorbs its surrounding landscape, the bright spheres act as a series of portals to alternative perspectives.

1908 InOUT

Chilled evening at the Science Gallery for Zen-On a collaborative presentation from artist Ansuman Biswas and astroparticle physicist Chamkaur Ghag.

‘We have many tools at our disposal to gather information about the world. Physicists are tuning their instruments to an unprecedented level of sensitivity. Even burying super-cooled xenon under a mountain in the hope of detecting the faintest, most elusive particles of matter.

Ultimately, however, whatever external instruments we use, all data is experienced by our bodily senses. These senses turn out to be more finely tuned and calibrated than anything we have yet invented. And they are available to all of us, for free.

In this interactive performance we will draw parallels between the physical world around us and the physical experience of the body. We will explore the instrumentation we have available to us and discover its limits and possibilities in search of the subtlest and most elusive elements of reality.’

1908 zen-on polaroid

I enjoyed the parallels drawn between the search for dark matter and the search for inner peace, both of which require PURITY, QUIET and SENSITIVITY in processing data, looking for patterns and understanding knowledge.

The Dark Matter exhibition at Science Gallery was not so inspiring in its curation but there were a few nuggets to be gleaned.

Through the AEgIS from Semiconductor

1908 Science gallery semiconductor

Images gathered from data captured from the AEGIS experiment based at CERN of violent collisions between matter and antimatter, along with tracks of newly created particles, all of which are too small to see with the human eye reveal the chaos of the unseen.  The artists call it a “space time-lapse” work, showing an animation created from around 100,000 still images.

Mirror Matter by Emilija Škarnulytė

1908 Science gallery Emilija Škarnulytė
In thousands of years, how will the gigantic structures dedicated to the pursuit of science be viewed? Will their remains be viewed the same way we think of Stonehenge or the pyramids – relics of a previous civilisation? Mirror Matter is set 10,000 years from now, with an all-seeing alien eye surveying the ruins of scientific machines that once probed and measured the Universe.

Olafur Eliasson In Real LIfe at Tate Modern works well for social media posts but on the day I felt mostly disappointed with one or three exceptions, this may be because it was like an unruly crèche or being swamped with spectacle.

Reading Timothy Morton ‘Being Ecological’ I started off thinking I am going to love this book but after a chapter of multiple examples of how to look at ‘being ecological’ this way or that way I was a bit frustrated. I missed the reading group to see how everyone else got on.

I did find it interesting to discover that the Anthropocene has a proposed official start date and it’s very recent – 1945 – the time when the first atomic bomb was detonated.

1908 nuclear explosion 1945.jpg

In January 2015, 26 of the 38 members of the International Anthropocene Working Group published a paper suggesting the Trinity test on 16 July 1945 as the starting point of the proposed new epoch.

A happy return to Allenheads Contemporary Arts for Continuum research.

1904 ACA 3 sphere

It is a place which pulls you in like gravity or a magnetic field. It would be no surprise to find a wormhole portal here.

Joined by Annie Carpenter, Nicola Ellis and Robert Good we spent the time reading, walking, thinking and sharing ideas.

“The miners did not find the riches they hoped for and the tunnel never reached its destination…”

Theoretically it is possible that wormholes exist. Every point in spacetime could be connected by a hidden web of tiny wormholes left over from the beginning when the universe was turbulent and unformed. Should they be discovered, to open them and pass through would require a colossal amount of negative energy which we are unable to create with current technology. However, there is a lot of metaphysical negative energy around at the moment so maybe this could be used to power a wormhole.

1904 ACA Blacksmiths.jpg

The Allenheads Blacksmith’s Forge seems a good place to open a wormhole portal. It is a place of high energy collisions and hot fusion.

1904 ACA Blacksmith window cill

It is also home to a collection of local rocks and crystals which must surely offer some negative energy cleansing properties. For research imagery my glass sphere encapsulates and condenses its surroundings. If the image is made to spin fractals begin to appear.

1904 ACA hearth

I also captured the landscape at speed as travel through the wormhole would exceed the speed of light.

1904 ACA at speed

I probed the depths of rabbit holes with an endoscope camera and discovered alien landscapes and the hidden web of the interconnected root system.

As the project Continuum focuses on ideas around speculative fiction the newly installed Museum of Classic Sci-Fi in Allendale made an interesting day out with an impressive collection of artefacts and information.

The Cosmic Sublime exhibition presented by Lumen Studios opened at The Pie Factory in Margate. The concept of the sublime has long been associated to both fields of astronomy. Derived from the Latin “sublimis”, the sublime is translated as “set or raised aloft, high up”- etymologically the word “sublime” is very much linked to the space above our planet and to what may inhabit it.

I was pleased to show the video Soft Borders made with dance artist Paola Napolitano.

1904 Cosmic Sublime Susan Eyre

The video speculates on the idea of a universe that is a finite shape but has no borders. If we were able to exit at one point we would immediately re-enter at another point. It also considers our body in a similar way with open borders for the unseen passage of cosmic rays and other particles.

Thanks to artist Rosie Reed Gold for some great photos of the show.

My wonderful optician John Rose spent some time scanning my iris for me.

1904 iris scan infrared

This is for work I am planning looking at the possibility that we retain some residual magnetoreceptor in our eyes that once enabled us to navigate using the Earth’s magnetic field. And other ideas.

In 2019 the Lizard is celebrating the 400 year anniversary of Sir John Killigrew’s building of the first lighthouse on Lizard Point in 1619. The lighthouse also has important links to the search for reliable Longitude measurement, with an assistant to the astronomer royal visiting the lighthouse at the time of the first Transit of Venus to record an accurate location for the Lizard Rocks.

Following on from the Lizard Point Residency I have made a mock up to test the Fresnel lens projection work. A film exploring entanglement and communication across distances will be back projected onto the lens.

Joined by Anne Krinsky and Carol Wyss, we made another site visit to St. Augustine’s Tower in Hackney and made some decisions about who would install where for our upcoming group show which will be titled Reading Stones.

1904 St Augustines Tower Clock

Reading Stones were the original tool for magnifying text, first made from polished glass or crystal in the 13th Century – the same era the tower was built.

I will be installing in the room that houses the clock mechanism. It is a wonderful animated machine. On the way home reading Carlo Ravelli’s book The Order of Time I came to the passages quoting from St. Augustine.

“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. Either this is time, or I have no idea what time is.”

1904 St. Augustine

The British Library have released some excellent scans from their archives for free use.

1904 time and eternity

While in Suffolk visiting family I made a detour to Dunwich and found the tide clock has become redundant.

1904 tide clock

Time and Tide wait for no man. The earliest known record is from St. Marher,  1225: “And te tide and te time þat tu iboren were, schal beon iblescet.”

In my present, the ruins of Greyfriars Monastery at Dunwich where large chunks of the coastline have fallen into the sea.

This is an amalgamation of images from the ruined Waverley Abbey and St. James Church Weybridge – not ruined in my present. Sanctified spaces drawing people to them who seek transformation. All matter becomes regenerated.

I liked this work looking at big data. I was intrigued how the multiple projections were installed, baffling as only two projectors in the room and neither seemed to be pointing in the right direction.

Great installation looking at the moon from an earthbound perspective from Shaney Barton. Anomalous Mass is showing at Allenheads Contemporary Arts Gallery as part of the Continuum series of events. Multiple screens show footage captured of the moon over a ten-month period with found dialogues on recent moon histories and projected near futures of the moon race and plans for human colonisation.

Wonderful poetic visons, some realised some imaginary from Katie Paterson at Turner Contemporary with A place that exists only in moonlight.

1904 Katie Paterson1904 Katie Paterson 2

Like Paterson, JMW Turner was fascinated by the sublime wonder of nature, capturing the changing and atmospheric qualities of light, air and weather in his paintings, while also being deeply curious about science and the physical world. Paterson has selected a group of over 20 Turner watercolours and paintings to be interspersed with her works.

Also on display were some of Caroline Herschel’s notebooks describing her extraordinary astronomical discoveries of comets made by patient observation.

Great to be able to see the screening of Sarah Sparkes film Time You Need and her GHost Tunnel installation in The GHost Parlour at New Art Projects. The GHost Tunnel references portals, black holes and equates time travel with death as another dimension that we may enter.

1904 Sarah Sparkes

The film gently leads the viewer on a journey beyond the physical and explores the potential for consciousness to time-travel within the material limits of the human body.

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.

1903 lighthouse beam

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

1903 lizard lighthoouse

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.

1903 lighthouse lens 21903 semaphore station1903 triangulation point1903 radio station

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.

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.

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

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.

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.

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.

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.

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.

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.

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.
