‘And here is one of the map’s most important characteristics: the viewer is positioned simultaneously inside and outside it. In the act of locating themselves on it, the viewer is at the same moment imaginatively rising above (and outside) it in a transcendent moment of contemplation, beyond time and space, seeing everywhere from nowhere.’ Jerry Brotton in A History of the World in 12 maps

Locked down editing video work. Setting off at dawn and wearing a headcam I walked the most direct route to each of the four points due North, East, South and West of my home. I chose a three mile radius as this approximates the distance to my horizon at sea level.

I am interested in how space is perceived as a plotted dimension, as abstract space calculated mathematically but perhaps not something we can visualise and as imagined space.

I aim to relate these different perspectives on space to broader knowledge. In my film there are three speculative viewpoints; ‘the seeker’ who wishes to discover what is beyond the horizon, ‘the seer’ who imagines what might be beyond and ‘the scientist’ who offers abstract theories.

In the film I explore connections and hierarchies of physical dimensions and perception, the use of contour lines on maps, foliation and patterns in soap film membranes or marbling.

Foliation is the decomposition of shape into lines and circles. It occurs in geology as repetitive layering in metamorphic rocks and in mathematics as the analysis of curves and surfaces. The math’s language is way beyond what I can understand but it does have connections with holonomy and manifolds and Poincaré which I am interested in though I am yet to get to grips with any firm understanding. The notion of leaves (slices) allows for an intuitive way of thinking about a foliation. In mathematics, topology compares shapes to see if they have the same number of holes and handles and can therefore be moulded from one shape into the other by stretching, twisting, crumpling and bending, but not tearing or gluing.

I took many films of soap film membranes and have been exporting the final single frame at the moment the bubble bursts. I have used these frames to create sequences of collated membrane bursts. We may live in a multiverse of bubbles each with wildly different laws of physics. String theory allows for many universes with different physical laws. It may be possible our universe could suddenly transform into a universe with different properties. If it did happen it would be so fast we wouldn’t even register it.

I made a silver cape for some green screen filming in character as the seer. Learning lots about Adobe After Effects so if the editing requires I drop this section then the hours put in won’t be entirely wasted and the cape will come in for when next door can have their parties again.

Thinking about making new work that interacts in real time with cosmic rays as they hit the Earth’s atmosphere and shower down upon us.

Cosmic rays, some travelling from other galaxies, pass through us and our world continuously, creating an almost tangible contact with outer space. Witnessing this incredible activity helps us look beyond what our immediate senses tell us exists and consider the interconnectedness of our universe.

We are made of carbon. Most of the carbon in the world is carbon-12 which contains six neutrons and six protons. 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 particles created are neutrons which can smash into atoms of nitrogen to create carbon-14 which has six protons and eight neutrons.

Cosmic ray activity gives us carbon dating techniques. Carbon-14 is unstable and therefore radioactive. It has a half-life of 5,730 years. This means if a sample of a tree contains 64 g of radioactive carbon, then after 5,730 years it will contain 32 g, after another 5,730 years that will have halved again to 16 g. 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.

Carbon-14 atoms in the atmosphere combine with oxygen to create radioactive carbon-dioxide. This radioactive carbon-dioxide is absorbed by plants which are eaten by animals. When an organism dies no more carbon-14 will be absorbed. The existing carbon-14 will start to decay. By measuring the radioactivity, the current carbon-14 content can be determined and the time of death established.

A planet with twice the mass of Jupiter has been discovered orbiting HD70642 in an almost circular orbit. This means it is possible that Earth-type planets may be orbiting further in. In all other planetary systems discovered with massive planets they usually have disruptive closer elliptical orbits which would destroy any smaller planets on a circular orbit. Hope to return to my studio soon to continue work on ’90 light years home’ which will use a raster pattern on folded paper looking at mapping out a space ship as a star map using 137 points. As physicist Laurence Eaves states – ‘The number 137 would be the one you’d signal to aliens to indicate that we have some measure of mastery over our planet and understand quantum mechanics.’

137 comes from the fine-structure constant, also known as Sommerfeld’s constant and is represented by the alpha symbol α. Using several fundamental constants found in nature to give a fundamental physical constant. This number represents the strength of electromagnetic interaction between elementary charged particles which is the probability that an electron will absorb a photon.

I watched the Hito Steyerl lecture as part of the Dramaturgies of Resistance online event series.  ‘At this unprecedented time, when it seems as if “everything is canceled,” Steyerl’s most recent work explores the complex relation between spread (of conspiracy theories no less than viral contagion) and simulation (from the automization of performance to our capacities for virtual interaction with statistical probability of human risk).’

I was excited to find the lecture covered topics very relevant to my research into abstract space at the moment such as objects in topology. The Alexander horned sphere is a pathological object in topology. It is formed by starting with a standard torus, removing a radial slice of the torus and connecting a standard punctured torus to each side of the cut, interlinked with the torus on the other side. A pathological object is one which possesses deviant, irregular or a counterintuitive property, in such a way that distinguishes it from what is conceived as a typical object in the same category.

The opposite of pathological is well-behaved.

Mathematician Shing-Tung Yau set out to discover if there could be a spacetime which contains no matter but in which there is still gravity caused by the topology of the space. In 1977 he solved the Calabi Conjecture posed by Eugenio Calibi in 1954 who was interested in whether a certain type of topology guarantees a certain type of geometry. Topology looks at the overall form of an object and recognizes shapes that have an equivalent topology but different geometry such as a doughnut and a coffee cup as they can be morphed from one to the other. Topologists generally study manifolds. Manifolds are shapes that could be flat when looked at close up such as the earth’s surface or a ball if you were an ant. Each point on the surface can be mapped using two coordinates onto a 2 D plane and the shape is finite. Taking the average of all the curvatures at every point on the surface gives what’s called the Ricci curvature. A doughnut which is a 2D manifold mapped in this way has a Ricci curvature of zero which shows that a manifold can have a zero Ricci curvature at every point without being flat. There are also shapes which look 3D when seen up close and need 3 coordinates to map them. In mathematics it is possible to think of Euclidean (flat) space in any number of dimensions by increasing the number of coordinates you use giving manifolds in many dimensions. Transferring this equation to physics Ricci curvature describes the curvature of spacetime that’s induced by matter being present if this curvature is zero then it describes a spacetime with no matter. Yau proved that this type of manifold could exist in all dimensions. This type of manifold is known as the Calabi-Yau manifold. Particularly in superstring theory, the extra dimensions of spacetime are sometimes conjectured to take the form of a 6-dimensional Calabi–Yau manifold, which led to the idea of mirror symmetry.

I took a couple of online geometry courses with The Princes School of Traditional Arts.

Mapping the Cosmos class was based on the geometry and symbolism of the Cosmati Pavement at Westminster Abbey which was laid in 1268.

The Geometry of Sound class looked at Chladni patterns which occur on a rigid surface caused by various modes of vibration.

We begin each drawing with a circle intersecting a horizontal line. The horizon where heaven and earth touch.

I am about to follow up on some of the recommended further reading.

Other reading has provided some mind blowing facts. Thanks Jim Al-Khalili.

There are scientists measuring time in attoseconds. There are more attoseconds in a single second than there have been seconds since the big bang.

Atoms are incredible tiny; you can fit more atoms into a single glass of water than there are glasses of water in all the oceans of the world.

In the studio I have been experimenting with magnets and iron filings while thinking about magnetoreception, methods of navigation and finding the way in the dark.

2002 magnetoreceptor wip 1

Some interesting research at the Max Planck Institute headed by Dr Christine Nießner has been looking at the light-sensitive molecules that exist in bacteria, plants and animals which are used for perception of the Earth’s magnetic field to aid orientation and navigation.  In birds the cryptochrome molecule is located in photoreceptors in the eyes and is activated by the magnetic field but only reacts to the magnetic field if it is simultaneously excited by light.

An additional meaning to birds eye view.

In animals, these molecules are also involved in the control of the body’s circadian rhythms. The researchers think that some mammals may also use this cryptochrome to perceive the Earth’s magnetic field. In evolutionary terms, the blue cones in mammals correspond to the blue- to UV-sensitive cones in birds. It is therefore entirely possible that this cryptochrome in mammals has a comparable function.

2002 magnetoreceptor wip 2Observations of foxes, dogs and even humans indicate that they can perceive the Earth’s magnetic field, but may perceive it in a different way, for example with microscopic ferrous particles in cells known as magnetite. A magnetite-based magnetic sense functions like a pocket compass and does not require any light.

Mole rats navigate their dark tunnels using this kind of compass. Birds also have an additional orientation mechanism based on magnetite, which they use to determine their position.

Continuing research for a collaborative event with UCLO looking at the planetary system most similar to our own Solar System which contains the bright star HD70642. It is visible with binoculars from the southern hemisphere toward the constellation of Puppis.  “The Stern”  (poop deck) was once part of the constellation Argo Navis. Argo was the ship that Jason and the Argonauts sailed on their quest for the Golden Fleece2002 star map Argo Navis

A planet with twice the mass of Jupiter has been discovered orbiting HD70642 in an almost circular orbit. This means it is possible that Earth-type planets may be orbiting further in. In all other planetary systems discovered with massive planets they usually have disruptive closer elliptical orbits which would destroy any smaller planets on a circular orbit.

At 90 light years away, extremely faint early radio broadcasts from Earth are now passing this planetary system. It was around 90 years ago when University College London Observatory first began exploring the night sky. It was also around then when my mother was born which gives a human scale to the journey time. The constellation of Puppis is only visible from the southern hemisphere but should there have been a radio broadcast about the opening of UCLO then this information would now have travelled to this potential alternative home.

Further research for a future video work The Seeker, The Seer, The Scientist. Looking to the horizon, the line that separates earth and sky.  The optical horizon is what we see but is not at the same as the geometric horizon which allows for the curvature of light due to atmospheric refraction. If the surface of the Earth is colder than the air above it, light is refracted downward as it travels around the curvature of the Earth and if the ground is hotter than the air above it light is refracted upwards causing a mirage.

2002 horizon

The true horizon is usually hidden.

2002 horizon sea

We each have a personal distance to the horizon based on our specific height of eye from the ground and the local elevation from sea level at which we stand. It is a distance we can never reach as it always recedes.  The seeker must send a seer to visit their horizon and report back on what it is they see, they may also send a scientist. The seer can see beyond, but is what they see real or imagined, the scientist can explain what is beyond but this is just abstract space.

My height of eye = 1.5m + local elevation

Distance to horizon = √(13 x height of eye)

Some interesting ideas in The Rosicrucian Cosmo-Conception, a 1909 text by Max Heindel which seem relevant to my meanderings intersecting cosmic particle trails with matter. This text, setting out a theory of seven Worlds and seven Cosmic Planes, supposes an intermingling of spirit with matter where the intersection of the material and metaphysical world are not one above another in space, but inter-penetrate each with the other.2001 cosmic planes

A brief look at what is current in Bloomberg New Contemporaries 2019 at South London Gallery

200219 new contemporaries

The Missing Day discussion on 29/02 as part of the The Habitat of Time programme at Arts Catalyst curated by Julie Louise Bacon was a cross discipline interrogation of the social, political and personal impact of how we order time.

  • Once every four years, here in the collective habitat of Earth time, 365 becomes 366 as the missing day of the leap year makes another appearance in the now-global calendar. This quadrennial occurrence foregrounds the essentially malleable nature of time. From the earliest lunisolar calendar developed in Babylon during the Bronze Age, to the invention of atomic clocks in the mid 20th century, and speculations on the quantum realm in the laboratories of today, time’s parameters have taken on new guises, shaping and regulating life in the process.

The Missing Day roundtable explores the development of human modes of measuring and understanding time, and their impact on the ways we order time as societies, individuals and a species. The discussion will bring together perspectives on observing, keeping and speculating on time from the fields of the history of science and physics. It will consider the emergence of the modern regimes of time that dominate social life, their limits and the possibilities beyond.

Chaired by the curator Emily Akkermans ‘Curator of Time’ at National Maritime Museum Greenwich spoke about the mechanics of horology and the trade and empire building that led to time keeping for navigation, transport systems, industry and financial markets. Artist Ted Hunt whose work is featured in the 24/7 Somerset House exhibition spoke about his attempts to deconstruct the clock and find alternative methods of recording time. Artist Ami Clarke from Banner Repeater had a stark message about capitalism driving our relationship to time, taking control away from the human as algorithms respond to twitter announcements and fluctuate markets faster than humans can intervene to prevent malfunction. Particle astrophysicist Cham Ghag was present to give insight into how time does not exist in physics apart from in the law of thermodynamics. All other processes are reversible but heat can only travel in one direction. He also spoke about the importance of good quality sleep and disengaging from the demands of 24/7 ordered time.

24/7 – A WAKE-UP CALL FOR OUR NON-STOP WORLD at Somerset House. With over 50 works it was a bit of a sensory overload in itself but thankfully interspersed with meditative works that gave some respite. An urgent analysis of sleep deprivation, disrupted circadian rhythms and non-stop culture.

The current new materialisms reading group book is Posthuman Knowledge by Rosi Brandotti who writes about complex multiplicity and a global exhaustion from having to negotiate new technologies, the political landscape and climate urgencies, like surfers riding an ever increasing number and magnitude of waves. How do we position ourselves (we who are in this together but are not the same)  in a world where we must distinguish ourselves from non-human (I am not  ROBOT) yet embrace and include the non-human; confer rights to nature; dismantle dualisms?

The question of what is it to be human is wonderfully scrutinised in Caryl Churchill’s play A Number which looks at human cloning and identity, particularly nature versus nurture in making us who we are. The story, set in the near future, is structured around the conflict between a father and his sons – two of whom are clones of the first one. The original son feeling loss of self, the second son feeling a poor copy, and subsequent sons freed of guilt or jealousy or lacking in introspection and depth.

Research Network: Ecological Sci-fi – Artist talk with Stephanie Moran and Keiken at Inniva.

Scientists have been incorporating more and more attributes based on animal perception and behaviour into media, a process that has been intensifying since the beginnings of Modernism, from steam engines to AI (Lippit, 2000; Parikka, 2010). If we are already cyborg, we are also already interspecies cyborgs, albeit in anthropocentrically instrumentalised, alienated form. As artist Jennet Thomas’ dystopian sci-fi film proposes, “The category ‘human’ is falling apart…” (Animal Condensed>>Animal Expanded#2

Stephanie Moran’s PhD research considers how to think about ourselves as part of a shared ecosystem and to consider the embodied experiences of other species that share our world but inhabit very different experience-worlds. Unfortunately I found it hard to hear and follow her talk, and keep pace with the slides. I’m sure there was a lot of interesting information that escaped me. I did pick up the mention of magnetoreception though.

Astrobiology researcher Professor Lewis Dartnell gave an interesting talk at Conway Hall Origins – How the Earth Made Us

Geological forces drove our evolution in East Africa; mountainous terrain led to the development of democracy in Greece; and today voting behaviour in the United States follows the bed of an ancient sea. The human story is the story of these forces, from plate tectonics and climate change, to atmospheric circulation and ocean currents.

Slow time. Norwegian choreographer Ingri Fiksdal presented Diorama at Greenwich on a thankfully bright February lunchtime.

These performances reflect on the passing of time, on the slow change in landscape, and scenography as an ecological practice of bodies both human and non-human.

The word “diorama” often refers to a three-dimentional model of a landscape, such as displayed in museums of natural history. Another use of the word is for the French diorama theatre, invented by Louis Daguerre in 1822, where the audience were sat watching big landscape paintings transform through skillfully manipulated light, sound effects and live performers.

In mathematics, topology compares shapes to see if they have the same number of holes and handles and can therefore be moulded from one into the other by stretching, twisting, crumpling and bending, but not tearing or gluing.

Topologist Dr Mehdi Yazdi gave an introduction to mathematical concepts in topology, manifolds and foliations from abstract space to the expanding rings of trees found in nature. Foliation is the decomposition of shape into lines and circles. We gained visual inspiration from hands on participation with marbleised paper.

Michael Pollen’s excellent book How To Change Your Mind  sets out a fascinating history of psychedelics bringing us up to date with current research and future potentials for treating addictive behaviour as well as offering well adults access to an alternative consciousness. Told through his own experiences using LSD and psilocybin under guidance and his many interviews which researchers, practitioners, therapists and volunteers one overarching theme that comes out is a feeling of transcendence to another plane of consciousness which many interpret as becoming one with the universe or feeling the presence of god and an overwhelming sense of love. Could this chemical be the catalyst to opening receptors in our brain enabling us to access a consciousness present in the universe outside our body or are the emotions, visions and dissolution of ego experienced by those taking psychedelics all taking place within the brain?

Pollen quotes from Aldous Huxley’s experiences documented in his 1954 book The Doors of Perception where he describes an unmediated access to realms of existence which is always present but kept from our awareness by a “reducing valve” of everyday waking consciousness a kind of mental filter that admits only a “measly trickle of the kind of consciousness” we need in order to survive. A bit like us only seeing certain wavelengths of the electromagnetic spectrum.

The title comes from William Blake’s 1793 book The Marriage of Heaven and Hell which expresses a unified vision of the cosmos in which the material world and physical desire are equally part of the divine order. It would not be hard to imagine Blake’s visions rooted in a psychedelic experience.

2002 William Blake

Over 250 years after the young William Blake saw a vision of an angel in a tree on Peckham Rye, Flat Time House has commissioned six poets to bring their words and visions to Peckham. Each of the poets has been commissioned to write in response to the life and work of William Blake and/or in response to that other creator of cosmologies, John Latham.

Poets in Response to Blake is part of the exhibition programme The Bard – William Blake at Flat Time House. The evening I attended we gathered to hear Chris McCabe, Niall McDevitt, Karen Sandhu and Iain Sinclair read from their commissioned works. It was such a treat to hear the spoken word live. A time to listen and reflect. Each of the contributions was evocative and insightful. I like that Iain Sinclair suggested John Latham was of such an expansive mind that he spanned time and consequently predated Blake.

“Spectral Latham pre-deceases William Blake,

      while both magicians,

burning like thermal lances, are numbered among

     the chain of stars.

Curved light reaches through infinitely extended

   quantum crumbs,

Planck time, to a black metal box that flattens,

   swept by paper waves,

into a cemetery suburb on the hill. Angelic incidents

   are reported”       Iain Sinclair
