When cosmic rays smash into the nuclei of gases high up in the atmosphere a variety of secondary particles are created but the only ones typically long-lived enough to make it to the Earth’s surface are muons. Muons are heavy electrons with a lifetime of 2.2 millionth of a second before they decay into an electron and a neutrino. Muons are typically produced around 15 km up in the atmosphere, a distance which takes around 50 millionths of a second to cross at the speed of light. This is over 20 muon lifetimes so they shouldn’t be able to get to Earth’s surface before they decay. However, since they are travelling approximately 98% the speed of light, time in their frame of reference is significantly stretched relative to time we experience on Earth. This means that they can travel much further in a shorter period so many Muons do make it to the surface. Special relativity is mind boggling.

Particles that arrive on Earth can cause computer processor bits to flip from one to zero or zero to one. The larger the computer is and the higher the altitude where it operates the more data corruption can occur. There are procedures to enable high altitude supercomputers like those at Los Alamos National Laboratory, birthplace of the atomic bomb, to detect when a bit is flipped and raise an alarm to force a crash and system reset. The big problem is silent corruption that neither the computer or human notices that could occur in sensitive data such as nuclear weapons stewardship and modelling for national security, space exploration, climate change, disease transmission, new drug trials etc.

This is all research and stills from my video commission Cosmic Chiasmus for Queen’s Hall Digital which will be going live soon.

Further work on sculptural piece 90 light years home joining all the individual tiles to make raster patterns of fragmented data transmissions. Made from a combination of screen print on textile, dye sublimation print and chinagraph pencil.

These are scrambled messages to outer space. This work is based on the raster patterns of the first TV signals when images were transmitted in a series of lines. It is a systematic process of covering an area progressively, one line at a time. It is similar to how one’s gaze travels when one reads lines of text. 

HD 70642 is a star about 90 light years away. It has roughly the same mass and radius as our sun. It has a companion planet that orbits in a circular motion very similar to how the planets orbit in our solar system. Waves like FM radio or television signals can pierce the ionosphere and travel through space at the speed of light. The first radio and TV signals from Earth will be reaching this solar system about now.

The work for my planned cosmic ray detector interactive artwork is still at the sourcing components stage. I am gradually gathering many small packages containing mysterious miniscule parts with worrying warning labels. No mention of the handling precautions in the HOW TO video! Also certain items seem to be difficult to get hold of at the moment with shipping dates set to next spring.

I have sent off for the custom printed circuit boards from China with fingers heavily crossed.

The detector works on the basis that when a charged particle passes through a scintillating material, part of its energy is absorbed and re-emitted as photons. A light sensitive device called a silicon photo-multiplier (SiPM) coupled to the scintillator observes these photons. A single photon can make a measurable signal in the SiPM and can be amplified to shape the signal in such a way that it can measure both how many photons were observed and at what time they arrived using an Arduino Nano. I am hoping to divert that signal to set off a script controlling a layering of on screen images which generatively decay as each cosmic ray pulse is recorded.

In 2019 for the exhibition Reading Stones I created the site specific installation Time Crystals in the ancient St. Augustine’s Tower in Hackney. 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.

In the news recently is the actual realisation of time crystals, a wholly new phase of matter to add to solids, liquids, gases and plasma that we are familiar with. Solid crystal structures repeat patterns across space whereas time crystal patterns repeat over time. Google researchers in collaboration with physicists at other universities have used Google’s quantum computer to produce this special phase of matter that changes constantly between states, but doesn’t appear to use any energy. All other known phases of matter are in thermal equilibrium meaning their their properties don’t change with time if the temperature is constant and settle into a low energy ambient state. Electronic computers use the binary system of 1s and 0s, on or off to process data. In a quantum computer, quantum bits have more possible states than just on and off adding uncertainty to outcomes. Qubits are unstable, acting differently when they’re under observation but time crystals remain stable while constantly flipping states and may be a huge breakthrough for complex computing and data modelling.

Pleased to announce work has finally been installed through Dais Contemporary at the impressive new Taj St James Court Hotel. Two screen print pieces from the everydaymatters series which are informed by the percentages of visible matter, dark matter and dark energy in the universe, and C-type on aluminium Pairi Daêza based around the refencing by Plato of the dodecahedron as the Aether holding the stars in the heavens. Dissecting landscapes to discover the hidden structures of the universe.

Expanding my etching skills with photopolymer process under the expert eye of J. Yuen Ling Chiu. It’s all in the inking up. Ling is such a great teacher.

Trying more new skills with a Super 8 workshop run by knowledgeable enthusiast Ben Slotover who packed a lot into one day. I really enjoyed trying the different cameras and the dreamlike spattered effects of the final films. Definitely something I want to try again though I think there will be lots to learn to achieve good results. I think it might work well to revisit my paradise works with this medium. The nostalgic ethereal quality appeals for this especially with the expired Kodak film as this needs to be flooded with light to work well.

Enjoyed the super/collider hosted zoom presentation Finding Asteroids with Dr Maggie Lieu research fellow in Machine Learning and Cosmology at the University of Nottingham. As of April 2021, there are over 25,000 near-Earth objects and many of these are a potential risk to life here on Earth, but in the main asteroid belt between Mars and Jupiter, there is believed to be over 2 million asteroids, some of which can reach 1000km in size! Scientists are actively searching for new, and tracking known asteroids. Often, they won’t know for sure where an asteroid will hit or how big an impact it will make until a few days before the collision. Machine learning is being used to keep a look out for potentially hazardous asteroids heading towards Earth. Interesting to hear how cosmic rays interfere with the data searches for asteroids by mimicking the traces made by asteroids but at such a different scale.

I joined Aphra Shemza for her online digital painting and co-creating workshop. The workshop was great fun, centered around the shemza.digital project which is a collaboration with computer artist Stuart Batchelor. Shemza.digital is based on the work of Aphra’s grandfather, the well-known British/Pakistani painter Anwar Jalal Shemza. It was inspiring and at times shocking to hear the family history and his struggle for recognition against the racism of the institutions he came into contact with as a young art student at the Slade and beyond.


Rewarding visit to Night Shaking with The Ingram Collection at The Lightbox, Woking. A spinetingling collection of objects dredged from the subconscious on a Night Sea Journey accompanied by enlightening and poetic text

“On the ‘Night Sea Journey’, what we think we know is held up to be an illusion. Our minds cannot fully grasp the changes of consciousness that take place during this ordeal. Ego and persona are forced to give way. This difficult inner terrain holds within it a hidden potential to experience a dramatic transformation of consciousness”

Objects and paintings made by Chantal Powell and Dean Melbourne are brought together with chosen artefacts from The Ingram Collection as the artists draw us into the Dark Night of the Soul and the Night Sea Journey narrative.

Chantal talking here on the symbolism of crowns and boats in alchemy and transformation.

We are made of carbon, it is the basic building block in virtually every cell in our body. Most of the carbon in the world is carbon-12 which contains six neutrons and six protons. However about 15 miles above our heads radioactive carbon-14 is formed as neutrons from cosmic rays interact with the atmosphere.

Protons and atomic nuclei created by events such as exploding stars speed across space and collide violently with the Earth’s atmosphere creating a chain reaction of cascading particles. Some of these tiny travellers may come from distant galaxies or be created by phenomena that we are yet to discover. Our body is continuously permeated at a subatomic scale by these particles fired into our world – an almost tangible contact with outer space.

Carbon-14 has six protons and eight neutrons and has a half-life of 5,730 years. This means that after 5,730 years dead matter which absorbed Carbon-14 when alive will contain half the amount it had when it died and after another 5,730 years that amount will have halved again. Radioactive decay is random but in a sample there are enough atoms to work out an average time it will take for the nucleus to lose the extra neutrons.

This radioactive carbon-dioxide in the atmosphere is absorbed by plants which are eaten by animals and humans.

Cosmic ray activity gives us carbon dating techniques.

I am working on a video, Cosmic Chiasmus, meaning crossing, which I was hoping would be part of Queens Hall Digital programme but now I am not sure they are going ahead with the commission.

Plant time lapse filming is fascinating to see how plants are so animated just at a different time scale to us. Also I have recently finished reading Richard Powers Overstory, a very powerful sobering read, which celebrates the slow yet socially active time of trees.

At Coniston. We are left to imagine the past majesty of this ancient giant which was lopped so it didn’t drop branches on the cars in the carpark.

Carbon dating is performed by measuring Carbon-14 in organic matter. Radiocarbon decays slowly while an organism is alive but is continually replenished as long as the organism takes in air or food.

When an organism dies no more Carbon-14 is absorbed and that which is present starts to decay at a constant rate.

By measuring the radioactivity of dead organic matter, the current carbon-14 content can be determined and the time of death established.

The oldest matter that can reliably be carbon dated is about 50,000 years old. Currently techniques are being refined as they have often relied on the assumption that Carbon-14 levels in the atmosphere are constant but they are not.

The burning of fossil fuels which have lost all their radiocarbon dilutes the amount of Carbon-14 with carbon dioxide and nuclear explosions add huge amounts of ‘bomb carbon’ to the atmosphere. During planetary magnetic field reversals more solar radiation cosmic rays enter the atmosphere producing more Carbon-14. Also the oceans suck up carbon circulating it for centuries.

There are a number of uncertainties for dating shell.

On the surface of the earth two to three Muons pass through your hand every second, underground this is reduced to about once a month.

I collected a selection of images from the 1930’s including some from family, including my Mum aged 3, which I have tinted blue and had printed on sublimation dye paper for transfer to the tiles making up the raster pattern in the work in progress 90 Light Years Home. FM radio and television signals can pierce the ionosphere and travel through space at the speed of light. The first signals will have travelled about 90 lightyears now to arrive at a solar system very similar to our own. Fragments travelling through space for light years with the potential for alien life to decipher.

While searching for images to use as fragments of our world as it appeared about 90 years ago in old National Geographic magazines I came across some articles about balloon voyages in the 1930’s to the stratosphere to record cosmic ray activity.

Intrepid explorers. These early explorations were innovative but also dangerous. In July 1934 a flight developed tears in the balloon fabric at about 57,000 feet and began to break apart, as it did so the hydrogen in the balloon exploded and the crew had to parachute to safety.

Physicist Victor Hess had already made a series of daring ascents in a balloon to take measurements of radiation in the atmosphere. In 1912 he made an ascent to 17,000 feet during a near-total eclipse of the Sun to determine if the source of the radiation was coming from the Sun and made the discovery that it had to be coming from further out in space.

The stratosphere balloon Explorer II was designed to carry heavy instruments for cosmic ray measurements to a height of 13 miles and more above sea level.

Scientists designed a system of cosmic ray telescopes to record the numbers of cosmic rays coming in from several angles above the horizon. Most of the cosmic rays counted are secondary particles shot out from the atoms of the air by the primary rays entering and colliding from space. During this flight the height at which most secondary cosmic rays are produced was determined and the first records of bursts of energy from atom disruption by cosmic rays was made.

Also, the first track ever made directly in the emulsion of a photographic plate by an alpha-particle cosmic ray with enormous energy of 100,000,000 electron volts was achieved. Two boxes of photographic plates coated with special emulsion were wrapped in light tight paper and attached to the balloon gondola. When the plates were developed there were no visible images but when put under a microscope tracks could be seen where the particles had ploughed through the emulsion.

Early google earth. They also took the highest altitude photographs of the Earth ever made.

To record data they had a series of cameras set to take automatic photographs of the dials on the different apparatus.

Analysing air captured from the stratosphere.

On Earth we are protected from most radioactive particles by the atmosphere and the magnetic field.

It has been clearly demonstrated that birds are able to sense the direction of the Earth’s magnetic field and that they can use this information as part of a compass sense. It may be possible humans retain some residual magnetoreceptor in our eyes that once allowed us to navigate using the Earth’s magnetic field. Current research suggests that some people do indeed perceive magnetic fields, albeit unconsciously.

Work in progress on navigation by magnetic receptors. Working on a soft ground etching of my iris with aquatint. Not sure yet if I will use the plate or the print in the final work which will have iron filings activated across the surface.

First components have arrived from America for my attempt to build my own cosmic ray detector to create an interactive artwork. The plastic block converts the energy of the charged particle passing through to a photon which can be read by a silicon photo-multiplier and the information fed to an Arduino processor. Daunting and exciting.

Visit to Sutton Hoo where the ever increasing accuracy of radio carbon dating has provided astonishing clues to the past history of this intriguing site. Archaeologists can determine the age of objects in decades as opposed to centuries.

Sutton Hoo is the site of two early medieval cemeteries dating from the 6th to 7th centuries near Woodbridge, in Suffolk, England. In 1939 landowner Mrs Edith Pretty asked local archaeologist Basil Brown to investigate the largest of several Anglo-Saxon burial mounds on her property. Inside, he made one of the most spectacular archaeological discoveries of all time.

Past, present and future finds. Ancient trees. Burials of Kings. Amazing sword of beaten twisted wrought iron and steel. Basil Brown’s star charts.

The agency and aura of objects was investigated with the intent to generate new relations between objects and their associations with the world around them in the beautiful group show Can We Ever Know The Meaning Of These Objects curated by Sarah Sparkes and Kevin Quigley at Gallery 46.

I joined a zoom presentation from Sophie Williamson on her current project undead matter which dips into the deep time entanglement of geological ancestry. Leaving a mark in the past as a way of communicating with the future and creating a lineage for ourselves. Eras mingle with each other as ancient footprints resurface, ice melts, secreted narratives emerge. The permafrost holds vast amounts of carbon. Whole forests.

Zircon crystal contains radioactive uranium with a half-life of 4.5 billion years, which makes it useful for dating extremely old materials much much older than those containing Carbon-14. These crystals may hold clues to the origin of life. The carbon necessary for life may have arrived here in space dust from outer space via asteroids or comets.

Michael Armitage – Paradise Edict at the Royal Academy. Digital images do not do justice to the glow and vibrancy of these paintings. Can feel the heat pulsating with unsettling shape-shifting undercurrents.

180 The Strand with Ryoji Ikeda’s digital showcase was an intense assault on the senses using light and sound as medium to create immersive experiences. Brightness is the number of photons per second hitting your eye. Pushing the limits of what our senses can tolerate.

Took a trip to the Lake District to visit Brantwood, John Ruskin’s beautiful home to see Carol Wyss The Mind Has Mountains and Crown of Creation installations. Having seen the work that went into the printing of the large etchings at Thames-side Print Studio it was wonderful to be able to see the work finally installed and step inside the mysterious depths of the human skull; a space echoed by the surrounding mountains. The light installation is suspended in the dark chill of the Ice House vault, viewed from the top of rugged steps carved into the rock. Here the fragility of the human skeleton fades and glows accompanied by an evocative soundscape made by Natasha Lohan capturing the echoing chamber and the water that courses through everything.

HD 70642 is a star about 95 light years away. It has roughly the same mass and radius as our sun. It has a companion planet that orbits in a circular motion very similar to how the planets orbit in our solar system. Waves like FM radio or television signals can pierce the ionosphere and travel through space at the speed of light. The first radio and TV signals from Earth will be reaching this solar system about now.

Family photo 1930 Kessingland Beach. It has taken almost the equivalent of my Mother’s lifetime for the early transmissions to reach this potential home from home.

Work in progress.

The work is based on the raster patterns of the first TV signals when images were transmitted in a series of lines. It is a systematic process of covering an area progressively, one line at a time. It is similar to how one’s gaze travels when one reads lines of text. The word raster comes from the Latin rastrum, meaning rake. Patterns of line. The signal is sent in fragments and must be interpreted on arrival to make sense of the message.

Also working on a short video – Cosmic Chiasmus, looking at the journey of cosmic rays from distant galaxies to our planet. Chiasmus comes from Greek meaning crossing, like in the letter X.

Cosmic rays, some travelling from other galaxies, pass through us and our world continuously, creating an almost tangible contact with outer space.

Some super high energy cosmic ray particles that arrive on Earth have 20 million times more energy than particle colliders can generate. They may come from distant galaxies or be created by phenomena that we are yet to discover.

They may come from other dimensions.

First line of defence on Earth against the ionising radiation of high energy cosmic rays is our magnetic field which deflects many charged particles before they reach our atmosphere. Second line of defence against cosmic rays is Earth’s atmosphere. Most high energy particles that make it past the magnetic field collide with atoms in the upper atmosphere and break apart to create a cascade of secondary particles that shower down upon us. In losing some of their energy as they smash apart they are less dangerous.

I have a very short film Big Bang to be featured in the 2021 Birkenhead International Film Festival of films 30 seconds or less.

The scales of the universe are hard to comprehend and this 12 second video is an attempt to relate this unfathomability to the human experience. Each second of the video is comprised of 24 single frame extracts from 24 separate videos of the moment a soap film membrane burst. Too fast for our eyes to see, we cannot register the individual frame or the instant the bubble bursts. This is nothing compared to the speed at which the Big Bang exploded matter across the universe or the magnitude of time that has passed since that event. As scientists use ever more sensitive instruments of measurement we must try and grapple with concepts that our limited senses have no hope of experiencing directly.

According to theoretical physics higher dimensions exist where space acts very like a soap film membrane in trying to minimize surface area. String theory, which attempts to combine quantum mechanics with general relativity potentially allows for many universes each with different physical laws.. It may be possible for our universe to suddenly transform into a universe with completely different properties. If this did happen, it would thankfully be so fast we would be oblivious to the moment of transition.

Out of the studio. Wonderful to be able to visit exhibitions again.

Tuned in to the webinar Art in Flux: The Invisible In collaboration with National Gallery X | Curated by Olive Gingrich

In a time, when there are nearly as many pieces of digital information as there are stars in the universe, contemporary artists explore new forms of making this vast amount of information accessible – be it through visual interpretations or new forms of interactivity. While museums around the globe including The National Gallery revisit their collections through the prism of data, contemporary artists such as Refik Anadol, Marshmallow Laser Feast and the Analema Group develop new processes for audiences to experience invisible phenomena in all new ways.
