An occasion on which one is reminded of the state of things in the real world.
Carlo Rovelli was at Second Home discussing his book Reality Is Not What It Seems: The Journey To Quantum Gravity which presents the story of the human imagination and reveals how the atomic world view first proposed by Democritus nearly 2,500 years ago can be found interwoven through history into our cultural life. It tells the story of what we know about our universe and how we came to know it, from the early atomic intuitions of Greek and Roman thinkers who observed the world about them and came to the conclusion that objects could not be a continuous whole but must be made up of lots of tiny parts.

The book goes on to show evidence of the ancient ideas now emerging from the Planck satellite and CERN, to the genuinely new knowledge being offered by Loop Quantum Gravity, of which Rovelli is a founding theorist. He was a generous and thoughtful speaker. When I started his book I was a little upset to find Plato to be considered obtuse and an obstacle to the progression of physics for ignoring the atomic theories of Democritus and questioning the benefits to itself of why an object should take a particular form, but then in chapter two Plato is absolved of criticism for his pioneering understanding that mathematics is at the root of all scientific truths that ‘Number governs forms and ideas’

The talk moved on to discuss the nature of time and how we experience it. Someone quoted Nelson Goodman from 1951 in The Structure of Appearance. ‘A thing is a monotonous event; an event is an unstable thing’.
I found this clip of Brian Cox explaining time travel sort of helpful in that I can follow his explanation but it still leaves me confounded.
In his book Rovelli equally values the thoughts of poets and physicists who contemplate the same questions about the structures of the universe.
Marvelling at correlations between Dante’s plan of paradise, possibly inspired by the cupola ceiling of the Baptistery in Florence, that speaks of a spherical universe made of ever increasing circles that reach a point where the outer circle appears to be enclosed by those that enclose it – a poetic description of a 3-sphere.
Rovelli believes the universe cannot be infinite – ‘that’s too big ‘ – and he seems aligned with the 3 sphere universe theory that the universe is not infinite but has no boundaries. I found myself thinking – surely this must still sit within something? Still it was gratifying to find that this in line with Jean-Pierre Luminet and the Poincaré dodecahedral space which I have been fascinated by –
A positively curved universe is described by elliptic geometry, and can be thought of as a three-dimensional hypersphere, or some other spherical 3-manifold (such as the Poincaré dodecahedral space), all of which are quotients of the 3-sphere.
Another name for the Poincaré dodecahedral space is the soccer ball universe…..

We are still waiting for any definitive answers about the shape of the universe, whether it is infinite or finite, whether it is flat, positively curved or negatively curved, whether it is simply connected as in Euclidean geometry or like a torus which is flat, multiply connected, finite and compact among many other contributing possibilities. I have been doing some research on the Poincaré conjecture, mostly looking at the diagrams of the mathematical theories.
I came across the story of Russian mathematician Grigori Perelman whose theories ultimately proved the Poincaré conjecture and he was awarded the Fields medal. He declined the award saying he wasn’t interested in fame. Other quotes have him saying if he can control the universe why would he want to claim a million dollars prize money. Perhaps some myths have been built around him, as seems to happen with a person who doesn’t conform to expectations.
An earlier visit to Second Home was for a talk on Super Massive Black Holes by Dr. Meghan Gray.
I found her description of what a black hole is really helpful to try and visualise what is happening. The idea that space curves around matter. That really dense and heavy matter condensed into a small object makes a deeper pocket in spacetime.
The largest black holes are called “supermassive.” These black holes have masses greater than 1 million suns combined and would fit inside a ball with a diameter about the size of the solar system. Scientific evidence suggests that every large galaxy contains a supermassive black hole at its centre. The supermassive black hole at the centre of the Milky Way is Sagittarius A*, it is 4 million times as massive as the sun and 27,000 light years from Earth. The smallest ones are known as primordial black holes. Scientists believe this type of black hole is as small as a single atom but with the mass of a large mountain.
The most common type of medium-sized black holes is called “stellar.” The mass of a stellar black hole can be up to 20 times greater than the mass of the sun and can fit inside a ball with a diameter of about 10 miles. Dozens of stellar mass black holes may exist within the Milky Way galaxy.

Made a trip to Whitby for a site visit to Cleveland Ironstone Mining Museum ahead of our Laboratory of Dark Matters exhibition opening this summer.
We were given a very warm welcome and are looking forward to bringing our work to the North East. We are delighted that along with Arts Council England funding we have now received the support of The Institute of Physics and The Science and Technology Facilities Council to take our project to the mining museum.
I will be running some more cloud chamber workshops.
My second Open Studios and the first with the new management Thames-side studios who did an excellent job promoting the event, running activities and guiding visitors around what is quite a big site now.
Susan Eyre Pairi Daêza
The word Paradise originates from ancient Iranian pairi daêza meaning around and wall.
The work everydaymatters is informed by the discovery that the matter we know, that which is visible to us and includes all the stars and galaxies is only about 5% of the content of the universe, dark matter making up about 25% and the remaining 70% being dark energy, it dissects landscapes to discover the hidden structures of the universe.
Spent an interesting evening at Treadwell’s listening to Lore and Belief in the Case of the Talking Mongoose, a lecture by Chris Josiffe.
In the early 1930s, an isolated Manx farm family became international celebrities after claiming their home was inhabited by a weasel-like animal. Gef the Talking Mongoose could speak coherently, shape-shift and perform telepathy. Investigators came in their multitudes, and improbable though it may sound, many were convinced. It was a time when spiritualism was strong, and psychic investigation popular. Gef was purported to live between the walls of the house. This made me think of Gregor Schneider and his double walled rooms, lead lined, claustrophobic passages.
I made a trip to Brockley to see In Conversation with (7): Beyond Controls; a drawing and print collaboration between Neil Ferguson & Carol Wyss.
From an initial line, each drawing was scanned, emailed and printed out to be developed further by hand. The repetitive nature of these procedures regularly exposed the limitations and idiosyncratic qualities of the scanners and printers. The structure of “Beyond Controls …” would always be infinite, sequences without final drawings, but rather statements held in digitalized time. Cycles of series that cannot be closed, circles that cannot be joined.
The result was 10 sets of 32 drawings, 10 inkjet monoprints and a captivating video of each set of drawings digitally layered and edited with Photoshop making the decision on visibility of content through its own algorithms. Wonderful.
Another visit was to a new project space HEWING WITTARE in Walthamstow to see Shapeshifting – tactics to combat drowning featuring works by Chudamani Clowes, Rebecca Glover and Anna Liber Lewis.
The artists use the watery world as a metaphor for our current political climate in which the fight for survival, shelter and equality is growing tougher by the day….
Chud Clowes engaged in a perambulative performance dressed as an Urchin to highlight the journeys made across the globe by thousands of migrants often at the mercy of the oceans and elements as well as political currents that sweep them from place to place
We were led to Lloyd Park, site of the William Morris Gallery, for some squid and fish printing on one of the hottest days of the year.
Later the same day entering Edel Assanti gallery to see new work from Jodie Carey – Earthcasts the visual and the physical collided. In this white space 50 gnarled and towering sculptures created a landscape hinting at the cool depths of a silver birch tree glade or the snowy trunks of an alpine forest while the heat of the day still pulsated in my body and hung heavy in the atmosphere.
It was a rich experience oscillating between ancient responses to the multiple upright monument, the rituals of the standing stone yet could also be the concrete posts from some deconstructed enclosure, the high wire fencing removed. Jodie Carey’s painstaking process of burying old timbers in the earth to create casts that are then filled with plaster and subsequently excavated echo the temporal and material nature of our lives lived on soil and imprinted with our own encounters.
Along to SHOW 2017 at the RCA to be swept even further away. The heat more in keeping with the surface of Mars images presented as part of the final research of Luci Eldridge’s PhD by thesis; Mars, Invisible Vision and the Virtual Landscape: Immersive Encounters with Contemporary Rover Images 2017

‘ The eyes of the Mars rovers provide viewpoints through which we regard an alien terrain: windows upon unknown worlds. Rover images bridge a gap between what is known and unknown, between what is visible and invisible. The rover is our surrogate, an extension of our vision that portrays an intuitively comprehensible landscape. Yet this landscape remains totally out of reach, millions of miles away. This distance is an impenetrable boundary – both physically and metaphorically – that new technologies are trying to break.’ Luci Eldridge
I am reworking the dodecahedron frame for the mining museum. Sanding, then darkening with my favourite black Stabilo pencil.
The images of cosmic trails now sit behind Perspex facets which has added another layer of reflection, the outer world, the universe surrounding and surrounded by itself
Diazôgraphô = Greek for to embroider. As to embroider the stars on the heavens…
I’m not sure how this will ultimately feed into my work and the maths is way beyond me but I am excited by the possibilities it explores. I find this unpredictable world that operates on an unimaginably tiny scale fascinating. It is hard to grasp certain concepts as the theories cannot be visualized. Subatomic particles, physicist Richard Feynman tells us, do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen.
The movement of the shadows showed a lumpy pitted surface rather like earth. Maybe we weren’t so special after all.
With ever more powerful telescopes we have been able to determine that all the visible stars in the universe have their own solar system. We know this because as a planet moves across a star the light dips by a tiny amount, enough to be registered. The shadow of the planet gives it away.
