Let no man ignorant of geometry enter here.

Ben is in Florida with Jane visiting Rayburn and his family over Easter as usual at the moment.

We met in the Merton Apprentice last Thursday evening after work, before I drove to Wales on Friday and he flew out on Saturday.

He was talking about the number - or constant - Φ (phi) and how it appears in the proportions of, among many things, the human body? I said I hadn't heard of it and asked him if it was related to the golden ratio that the ancient Greeks knew about. He hadn't heard of that.

It turns out that Phi and the Golden Ratio are the same thing! Early in the last century a mathematician Mark Barr proposed using the first letter in the name of Greek sculptor Phidias, phi, to symbolize the golden ratio. Amazing eh? See https://en.wikipedia.org/wiki/Golden_ratio#History

When he is back, perhaps we can get together again, blow the froth off a couple of cold ones, and really start digging into the Fibonacci sequence?

I didn't see this one coming.
