I am aware that there are answered similar questions on here, however I am specifically after a text that would be engaging for a professor of mathematics, also Fellow of the Royal Society (FRS).
He is unwell and in the hospital, and I would like to get him something to pass the time. However anything aimed at undergraduate / postgraduate level is going to be far too patronising. Honestly, I’m not sure if there exists such a book, but if anyone has any recommendations, I would be extremely grateful.
Answer
I suppose that a very good choice is A History of Mathematics, by Victor J. Katz.
