Logically Policed

This is a nice short documentary by student filmmaker Damiano Petrucci about mathematics and mathematicians, why they do maths and how they communicate it. It’s got a load of names you’ll recognise, including Oxford’s Ben Green and Aperiodipal Matt Parker.

Mathematical soap bubbles by Juan Bragado

I recently tried to blow some clever soap bubbles to demonstrate some maths concepts to some students. It went terribly. Juan Bragado is much better at blowing mathematical bubbles, so he’s made this gentle video showing all sorts of soapy polyhedra, and other mathematical shapes made from bubbles.

John Conway on Numberphile!

Numberphile, the supremum over all YouTube channels, has scored a bit of a coup – Brady has sat down and recorded an interview with the famously Internet-reclusive John Conway.

In this first video (there’s a bonus one linked at the end of this one, and I hope there’ll be more) John talks about his love/hate relationship with his Game of Life.

By the way, I notice from the video’s description that the Mathematical Sciences Research Institute is paying for Numberphile these days. Thanks, MSRI!

NT matters (Wrapping up algebraic numbers)

Aperiodipal Nathan Barker sent me this video by Durham University’s Herbert Gangl, inspired by his number theory course last year.

I’ll never be able to think about algebraic numbers again without hearing this. Thanks, Herbert! No thanks, Nathan!
