In Closing: Ourselves

Do human’s consist only of quanta and particles? asks Rovelli. We know that he is going to answer yes and no. It’s not that simple he says. Well, he should try being me for a while, and trying to read a roadmap then he’d understand how complex it is. We humans, he tells us, are subjects that observe the world. But we know what’s coming next if we’ve been paying attention. We are also part of the world. A very small part of the world. A very,...

Sixth Lesson: Probability, Time and the Heat of Black Holes.

The problem of heat was one that perplexed mid-nineteenth century physicists. One way of understanding it was to think of it as a kind of fluid, ‘caloric’ fluid. I guess that’s where we get the term calorific value. Food equals a certain amount of energy. But in the mid-nineteenth century there was thought to be two kinds of heat: hot and cold. Wrong, of course, but not for the reason we think. James Maxwell and the Austrian physicist Ludwig...

Fifth Lesson: Grains of Space

Twentieth-century physics has given us two lodestars: general relativity and quantum mechanics. Some of the fruits of these are the study of cosmology, astrophysics and at more microscopic level, gravitational waves and black holes. Yet the two theories cannot both be correct, because they are, in essence, contradictory. The paradox is both also work in their domains remarkably well. Einstein’s Theory of All Things was a search for that...

Fourth Lesson. Particles

Atoms are the smallest things we can see. Each atom consists of a nucleus orbited by electrons. We’re looking more closely at the nucleus here. Each nucleus consists of protons and neutrons. If we go even smaller protons and neutrons are made up of even smaller units given the name quarks by the American physicist Murray Gell-man. The force that ‘glues’ quarks together inside protons and neutrons is called gluons. In medieval philosophy an...

Third Lesson: The Architecture of the Cosmos.

In response to The Daily Post's writing prompt: "Odd Trio Redux." Carlo Revelli (2015) Seven Brief Lessons on Physics, translated by Simon Carnell and Erica Segree. We’ve got a floor plan. In a reductionist world two features of space and time stand together in the battle-scarred macroscopic twentieth-century theories of Einstein. He explains how the cosmos came into being and hangs together. Contrast this with the mirrored microcosm of Bohr’s...

Second Lesson: Quanta

In response to The Daily Post's writing prompt: "Trick Questions." Carlo Revelli (2015) Seven Brief Lessons on Physics, translated by Simon Carnell and Erica Segree. If Isaac Newton is the father of physics, Albert Einstein is the mother, but he didn’t love all his children equally. Remember before Einstein, physics was spread out like a dirty nappy between subjects as diverse as Mathematics, Philosophy and the industry leader, Chemistry, in...

Carlo Revelli (2015) Seven Brief Lessons on Physics, translated by Simon Carnell and Erica Segree. First Lesson. The Most Beautiful of Theories.

First Lesson. The Most Beautiful of Theories. I just nipped out at lunchtime to get a bigger brain, but they were all out, the only thing left –on special offer- was a Simon Cowell brain. I said to the lassie behind the counter, ‘Do I look that fuckin’ stupid?’ ‘Or a two-for-one, David Cameron and… a black hole,’ she offered. I didn’t hang about, I’ve got better things to do with my time. Of course I don’t need a bigger brain. After all, quite...

Poetry on the BBC

Helen Ivory and George Szirtes (eds) (2012) In Their Own Words Contemporary Poets on Their Poetry. It’s poetry week on BBC 4. Last night I watched a drama that uses Simon Armitage’s poetry to dramatize the life and death of Sophie Lancaster in 2007. She and her lanky boyfriend were attacked in a park by a group of feral boys. Their attackers shoe prints and the pattern of their laces were left embedded in Sophie’s head. Black roses were the...

Pat Black (2011) Suckerpunch

Suckerpunch is a collection of 36 short stories and a Post Script. All for two quid to download, the kind of loose change that makes a five-year old wain scowl at you and poke their lip out when you hand it to them. It’s a great deal. Not all of them are of equal quality. I’m thinking, for example, a bit of ‘Tongue’ action here. I also think as we get nearer to the end of his collection, well, you know, there’s a bit of extra padding being added...

Under the Skin

watch this and weep Many years ago I read a short story about a woman with gigantic tits that picked up hitchhikers on the back roads. I think it was set in the Highlands. To be fair anywhere outside Old Kilpatrick is a bit like the Highlands to me, but it might have been closer to home. And I do read lots. Stories blend together and become a kind of fudge-cake mix. So if someone says have you read? I kinda have and kinda haven’t because until I...
