### 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.

### Domputer: the movie

If anyone remembers October 2012 (ahh, those were the days) you might recall we wrote about Aperiodipal Matt Parker, and his crazy project to build a computer out of dominoes. Well, it happened, but not much has happened since – sorting out a video of the event has taken a while. But it’s ready now! And it’s great!

### 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!

### Yoshimoto Friends

Here’s a happy little film starring two Yoshimoto cubes, by Justin Lanier and Paul Salomon of Math Munch. Enjoy!

### That Makes It Invertible! (by The Three Directions)

Put a smile on your face this Friday morning. Here, straight out of Harvey Mudd College, are the Three Directions performing their new smash hit, That Makes It Invertible!
