BBC Radio 4 put out a rather nice 30-minute documentary on the links between maths and magic recently. In *Maths and Magic*, Jolyon Jenkins explains a couple of simple algebraic ‘mind-reading’ tricks, before talking to various magicians and mathematicians in search of a mathematical trick that doesn’t ‘look’ mathematical. Regular readers of this site will recognise a few of the mathematicians featured in the programme.

I’m now a bit miffed that I managed to miss Jolyon at the big MathsJam in November, because the trick he ends with is the easy version of the de Bruijn trick that David and I made better last year.
