Insatiable Mind exhibition opened at Salisbury Arts Centre with space inspired food and a heartfelt speech from visual arts and exhibitions manager Mirka Golden-Hann who writes in the accompanying catalogue;

“I was driven by the overarching urge which is innate to humanity. The urge to break away, the urge to explore, the urge which would force a human to construct a spaceship and the urge of another human to step into it in order to walk on the Moon: the same compulsion behind the collective force to bring down the Berlin Wall and with it the Iron Curtain. It was the power of human curiosity and the dissatisfaction with the familiar that provided the basis for this exhibition.”

The installation of my suspended sculpture Pentacoronae was surprisingly smooth considering the height of the supporting beams.

There was a great team to help and although one or two anxious moments when hooks came away from loops it went up very well.

This work was made to highlight the importance and need to preserve dark sky areas. As powerful technology opens new areas of the universe to our view, generating imagery we could never see with our naked eyes, we are drawn to experience space via mediated technologies. Our ancestors mapped the stars and drew shapes across the darkness which became familiar anchors for navigation, described mythological characters and foretold fortunes. Through this work the viewer is encouraged to seek darkness, stargaze, wonder, and map their own stories across the sky.

I also had two concertina books installed in the gallery cabinet.

Making these books turned out to be quite a fiddly process.

For the book Unbound I used images from my cloud chamber printed on transparencies cut into pentagons. Cosmic Rays know no boundaries as they pass through us all the time. 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.’

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.

I has thought I would draw the energy fields in white china-graph pencil but it turned out graphite looked much better

The bright spheres are four colour separation screen prints and act as a series of portals to alternative perspectives.

I have been meeting up with students Sena Harayama, Romain Clement De Givry and Medad Newman from Imperial College Space Society.

1905 ICSEDS team

Supervised by senior lecturer in spacecraft engineering Dr Aaron Knoll they are building a cloud chamber to withstand a journey to the edge of the atmosphere in the payload of a high-altitude balloon. The chamber must be able to withstand the low pressure at high altitude which might make it break apart.

1905 cloud chamber

There needs to be a heat pad controlled by an Arduino processor to keep the batteries running to power the tracking device and cameras and maintain a suitable environment in the chamber to allow alcohol vapour to fall and create a cloud.

1905 Arduino

A cloud chamber enables us to see ionising trails made by radioactive and charged particles. Cosmic particles continuously collide violently with the Earth’s atmosphere then break up and shower down upon us.

Keeping the weight of components down is vital. The payload must not be over 2kg.

We are hoping to capture cosmic ray activity on video as well as a view of Earth’s atmosphere as it blends from blue into the darkness of space. This footage will become part of the video installation I am creating for Continuum midsummer weekend at Allenheads Contemporary Arts.

1905 enter portal

This new work Aóratos will be installed at Allenheads Blacksmith’s Forge.

Black holes were once thought to be pure science fiction but in recent decades scientists have discovered that these extraordinary objects exist throughout our universe in all shapes and sizes and this year astoundingly have even produced an image of one.

1904 Black hole image

Einstein’s theory of general relativity written in 1915 predicted the existence of black holes and is also consistent with the possibility of gravitational tunnels known as wormholes. It could be that there is a hidden web of planck scale wormholes linking all points in space. Theoretically, threaded through these tiny holes would be filaments of cosmic strings created in the primitive goo of early matter and flung across space when the universe burst into existence.

However, to traverse space by means of a wormhole would require vast amounts of negative energy, not something usually found on Earth yet in the current political climate in no short supply.

Making use of the Blacksmith’s hearth visitors will be invited to burn offerings of negative energy to power a ‘wormhole’.

1905 forge hearth.jpg

Special paper will be provided for people to write, draw or furiously scribble their own symbols of negative energy. These offerings will be burnt in the forge hearth releasing any pent-up negative energy to power the wormhole portal above.

I have been experimenting with chemicals to make the paper.

Really pleased with the results.

1905 magic fire chemicals
It’s fine. I am sealing the chemicals inside two sheets of paper so no skin contact for visitors.

1905 paper burn.jpg

In my search to discover how to make coloured fire I did make a visit to Davenports magic shop in a very unprepossessing but not uninhabited pedestrian subway. A dismal setting for a dismal shop where I got no help at all. Felt an absolute muggle.

1905 davenports magic shop

The risks and obstacles of entering a wormhole include creating enough negative energy to open the wormhole mouth wide enough to weaken the gravitational tidal forces which would rip travellers apart; keeping it from collapsing so travellers are not indefinitely trapped inside; exceeding the speed of light and avoiding incineration from deadly high radiation.

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

Aóratos translates as ‘unseen’. The videos in the installation will look at hidden landscapes and usually unseen perspectives. For research I have been exploring rabbit holes, bee holes, mice holes and abandoned tunnels with my endoscope camera.

A fascinating dark world of root webs and filaments interconnecting tunnels.

 

1905 turbulence.jpg

The reading group is persevering with Geoffrey West’s Scale despite the woolly editing and rambling digressions it does hold some interesting facts. I liked the section about turbulence. Fluid motion is chaotic and objects moving through water or air are subject to very different outcomes at different scales. Froude introduced a scaling methodology used in industry that has become increasingly sophisticated. Lord Raleigh emphasized the primary role of the ‘dimensionless’ number in scaling. This is a pure number such as pi which does not change depending on which unit of measurement is used, the ratio of a circumference of a circle to its diameter is always the same. “Pi embodies the universal quality of ‘circleness'”

Extraordinary that this majestic building piercing the sky has the most shallow of foundations and unless they keep a regular check on the water level through a little door in the floor the weight of the spire would not only bend the supporting columns but might tumble down.

I was excited to find a dodecahedron at the pinnacle amongst platonic solids topping an elaborate tomb.

New work pentacoronae installed at Grizedale Project Space for In Search of Darkness exhibition curated by art collective Lumen Studios.

1809 Pentacoronae

“Sky glow” is the yellow umbra leaching into the night sky from light polluting urban areas; obscuring our view of the constellations, shrinking our universe and severing our relationship to the stars.
Our ancestors mapped the stars and the shapes and patterns they drew across the darkness became familiar anchors for navigation; describing mythological characters; aligning celestial cycles with the fortunes of everyday life and revealing harbingers of portentous events. This rich history is being lost to a population bathed in the radiant intensity of artificial illumination.

1809 Pentacoronae 2
Light doesn’t always make things more visible. There are other ways to discover the mysteries of the universe and look beyond what our immediate senses tell us is there. Dark Matter is a significant component of the universe, yet we cannot see it. It doesn’t reflect or emit light and so scientists are finding other ways to detect it. In digital visualisations of Dark Matter, organic patterns emerge that could be the veins under our skin or the spreading branches of trees.

1809 Pentacoronae 1
As ever more powerful telescopes and data gathering equipment open new areas of the universe to our view, generating imagery we could never see with our naked eyes, we are drawn to experience space via mediated technologies. Dark sky areas such as Grizedale Forest are precious locations where we can still stargaze, wonder and map our own stories across the sky.

1809 Cloud Chamber demo

A cloud chamber gives us a glimpse into the invisible world of particles produced in the radioactive decay of naturally occurring elements and those generated when cosmic rays strike the top of the Earth’s atmosphere. It is a sealed environment containing a supersaturated vapour of pure alcohol sitting over dry ice. Charged particles passing through the chamber cause the vapour to condense resulting in tiny cascading trails. These particles pass though us continuously without our awareness. Witnessing this usually unseen activity can lead us to look beyond what our immediate senses tell us is there and consider the possibility of other intangible phenomena.

At the studio I am moving just across the corridor – mostly so I will have a window but I also gain more space which was great timing to lay out and assemble the suspended sculpture for Grizedale in an empty room.

Holly Graham Sweet Swollen at Jerwood Project Space. The seductive title is evocative of succulent ripened fruit but also the tenderness of a bruise. This poignant work draws on the history of sugar as a luxury brought to our shores in the 18th century with the taint of colonial violence and the demeaning of those forced to produce treats for European palates. A series of sugar lift etchings depict hands in isolation, the gestures originating from the stylised ‘blackamoor’ figurines that ornament receptacles of the bitter sweet cargo.

Highlights at this years New Scientist Live were talks from Jon Butterworth – Journeys into Particle Physics, Roberto Trotta – What Has Einstein ever done for you? and Dean Burnett – What makes your brain happy?

I came away thinking about what influences my perception of time and the chemicals that subtlety alter how I experience the world.

If you travel close to the speed of light, distances contract in your direction of motion, while time will dilate more and more the faster you move.  A muon lives: about 2.2 microseconds on average. The speed limit of the Universe = the speed of light. Something moving at the speed of light that only lives 2.2 microseconds, should make it only 0.66 kilometers before decaying. A muon has similar properties to an electron. However, it is 200 times heavier. Muons travel at approximately 98% of the speed of light. The closer you move to the speed of light, the slower your clock appears to run. Cosmic ray muons have such high energies that a journey which takes about 300 microseconds from our point-of-view only takes about 1 microsecond for the muon. Time dilation allows these particles to live.

I am beginning research for the High Altitude Balloon project. I need so much help! The good people of the HAB community are thankfully giving me lots of advice. One big concern is that the Allenheads Contemporary Arts potential launch site is high up and in the centre of a very narrow bit of the UK.  Wind makes for a difficult launch and could just take it straight out to sea.

1809 windy HAB.jpg

One of my first jobs is to check with the Civil Aviation Authority that the launch site is safe from their perspective.

18090 CAA.JPG

I want to film particularly at the altitude where peak cosmic ray activity takes place – this is where the secondary particles that we see in the cloud chamber are smashed into existence.  As the particle activity will be invisible I want to film the aesthetics of the curve of the earth and blue haze of the atmosphere bleeding into the blackness of space. I think my target height will be 30km.

1809 cosmic trails.jpg

Cosmic rays are mostly protons and atomic nuclei created in stars and super novae explosions or other unknown events.  Sometimes a rare one will arrive with unimaginably high energy. The first “Oh-My-God particle” was recorded in October 1991 and had an energy 40 million times greater than the Large Hadron Collider can generate with 100 quintillion the photon energy of visible light, it was travelling at 99.999 999 999 999 999 999 999 51% the speed of light. One of these could be passing through you right now.

 

I realised how much I have to learn about weather ballooning while attending the UK High Altitude Society Conference where I was kindly invited to give a short presentation about my hopes to launch my own balloon to film at the edge of the earth’s atmosphere. It was also Helium’s birthday and a cake had been prepared to launch into near space.

1808 UKHAS Balloon launch cake

I found much of the language of the day to be beyond my knowledge with many of the enthusiasts also keen coders and electronic wizards.

1808 UKHAS Balloon launch 1

Still my presentation received a warm response and I am hoping I now have some contacts to call upon as I begin to get to grips with the logistics and add to my list of what is required.

1808 UKHAS Balloon launch

There was a particular enthusiasm to actually launch a cloud chamber. This could be a first if we manage to achieve such a venture.

1808 UKHAS Balloon launch 6.jpg

It is all a delicate balance of weight, helium and wind direction.

The really tricky bit is the tracking and retrieval. I’m not sure yet if they did get it back as I haven’t yet mastered navigating the websites let alone the skies.

Came across this obelisk out in Wiltshire. It is rather stubby and further prevented from piercing the sky by the tree that has grown over the last 250 years to embrace it.
