Dispelling the myth that the walrus was Paul
In my experience there's nothing that can't be represented with the aid of a simple Venn Diagram. From showing the sort of people who use social networking websites to precisely what Meat Loaf would do for love, it can all be demonstrated by drawing a few coloured circles on a piece of paper. And for that we must thank Mr. Venn
John Venn (1834-1923) was born in Kingston-upon-Hull. A philosopher and logician, he studied at Cambridge where he was elected to The Royal Society. He introduced the Venn Diagram in 1881 with the publication of one of his many books, Symbolic Logic. Venn used them to explain set theory, probability, logic and statistics; I prefer to use them in pubs when I'm banging on about beer, music and football. But that's just me.
The University of Hull has a building named after him, where you can see this rather fetching stained glass window.
