## I think mathematics

Mathematics is my native medium of thought. The four years of my BSc degree in Mathematics, from 1966 to 1970, are the happiest years of my life, and the years in which I have felt most at home in the world.

I don’t distinguish between mathematics and logic. Either one can be regarded as a branch of the other.

This website will contain two sorts of mathematics pages: academic and recreational. The academic pages will be my PhD thesis, and my one published paper.

Meantime here are some recreational pages:

- 19‐ET and the Hebrew calendar (an account of a remarkable connection)
- A curious league table (a brief observation)
- A grain of sand in St Paul’s Cathedral (an essay)
- A scholarly critique of Stephen Leacock’s The Mathematical Problem of the Lost Chord (a tongue‐in‐cheek essay)
- Cricket in the shadows (a puzzle)
- Memory chips, log tables, Beethoven’s third piano concerto, and Who wants to be a millionaire? (an interactive essay)
- The number 31⁄88 in the context of tennis (an observation that is nearly trivial but not quite)
