"The ambiguity of the apple"

Alan Garner remembers Alan Turing (Guardian):

He was stocky, barrel-chested, with a high-pitched, donnish voice and the aerodynamics of a brick. He was funny and witty and he talked endlessly, but I understood very little of what he was saying, and it became clear that he ran in order to think. He seemed to be obsessed by mathematics and biology. That much I could work out.

We had one thing in common: a fascination with Disney's Snow White and the Seven Dwarfs, especially the transformation of the Wicked Queen into the Witch. He used to go over the scene in detail, dwelling on the ambiguity of the apple, red on one side, green on the other, one of which gave death. We had both been traumatised by Walt.

Also an appealing piece in Nature News, casting doubt on the claim (which I missed at the time) that cows are magnetic:

Three years ago, Hynek Burda, a zoologist at the University of Duisburg-Essen, Germany, and his colleagues added cattle to the magnetic family with a paper in Proceedings of the National Academy of Sciences. The team used data from Google Earth to show that domestic cattle seem to prefer to align their bodies along Earth’s magnetic field lines¹, and showed a similar phenomenon in field observations of deer. [...] Burda and his colleagues reanalysed the replication attempt by Jelinek and his colleagues⁴. Burda says that half of the Jelinek team's data should be excluded because some of the pastures are on slopes or near high-voltage power lines, for example, or because the images are too poor to make out cattle, or appear to contain hay bales or sheep instead. “One half of their data is just noise,” says Burda.

I wonder if Lydia Davis reads Nature News.

The horizon as a spit

I'm intrigued by Lydia Davis's chapbook The Cows, though it seems daft to pay $10 for 32pp. of observations about cows. A snippet from the Amazon page:

Forms of play: head butting; mounting, either at the back or at the front; trotting away by yourself; trotting together; going off bucking and prancing by yourself; resting your head and chest on the ground until they notice and trot toward you; circling each other; taking the position for head-butting and then not doing it.

I was reminded of a snippet from a Davis interview in the FT a couple of years ago, which I thought I'd blogged at the time but apparently didn't:

a photograph of two cows – standing in the snow like black cut-outs on white paper, staring flatly at the camera. Something about the picture is irresistibly funny.

She sent the photo, she tells me, to her friend Rae Armantrout, a poet, who called her afterwards. “She asked me why I had sent her a picture of two pigs strung up on a spit,” says Davis – and then turns the picture upside down.

I can see what she means; the line of horizon does resemble a wire, and the cows do look a bit like pigs. “It was just one of those confusions,” she says, shrugging.
