Alexander's latest book, on the mathematician Simon Norton is out.

Alexander's latest project, Simon Phillips Norton "To Simon, Simon is a collection of disparate facts and no interpretative glue.

He is a man without adjectives. His speech is made up almost entirely of short bursts of grunts and nouns" "This is the main reason why we spent three weeks together, and him with only three pairs of socks for the whole journey: I needed to find a way to make him prattle."
