*Birth of a Theorem*, the autobiographical book by French mathematician and (spoiler) Fields Medallist Cédric Villani, is Book of the Week on BBC Radio 4 this week, read by non-French non-mathematician Julian Rhind-Tutt. Villani also appeared on discussion show Start the Week on Monday, talking about ‘the mathematical mind’ along with mathematician Vicky Neale; Morgan Matthews, director of kid-does-maths film *X+Y*; and novelist Zia Haider Rahman.

Start the Week is available indefinitely on the Radio 4 website and in podcast form, and Book of the Week for thirty days after broadcast, after which *Birth of a Theorem *is available in printed and e-ink forms, read by your own voice in your head rather than Tom Boss, and complete with entire pages of raw-TeX-code-filled emails and unexplained equations which presumably will not make the cut for audio broadcast. If you finish it, why not help Cédric out with his Amazon page: it seems not many people have made it to the end so far.
