The next issue of the Carnival of Mathematics, rounding up blog posts from the month of November, is now online at X in Vogue.
The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. For more information about the Carnival of Mathematics, click here.
UK-based fans of the proposed UK Maths Museum will be exceedingly jealous to hear that New York’s mathematical visitor attraction, MoMath (the National Museum of Mathematics), is opening this month. Their opening weekend is 15th-16th December, and tickets are now on sale if you want to attend either day to take in their exhibits and activities.
For a taster of what the museum will be like, Time Out has a slide show of exciting pictures alongside a review.
For more information about the museum, visit their website at momath.org, or follow them on Twitter @MoMath1.

Fans of Tim Harford and his work on BBC Radio 4’s More or Less will be excited to learn he’s doing a new radio show about economics. In this post on his blog, he explains the show will be called ‘Pop Up Economics’, and consist of short stories about important people and ideas in economics.
The show is being recorded in the evening this coming Tuesday 4th December, in London, and if you’d like to go along, you can email firstname.lastname@example.org for tickets and details.

This Wednesday, friend of The Aperiodical Matt Parker compered an event at London’s O2 Arena in which the world record for most simultaneous Rubik’s cube solves was smashed by a crowd including schools groups, individuals, maths fans and the UK’s current speedsolving champion, Robert Yau.
According to this post on phys.org, which reports on this paper in science journal Nature, there’s some beautiful physics which results from tying knots in light. It opens, “New research published today seeks to push the discovery that light can be tied in knots to the next level.” Between us, I wasn’t actually aware of the discovery that light can be tied in knots (and I’ve done a fair amount of knot theory, and observed a decent quantity of light) – but apparently it’s something scientists have been exploring for years.
A spinning optical soliton (wave pulse) can spontaneously create knotted and linked structures, as the soliton curves around in space, and while previously it’s been observed after engineering them to happen, now the knots are forming spontaneously, like ” those annoying knots that you always get in electrical cables.” (see: here). The paper suggests similar behaviour might be seen in other types of wavefronts, such as superfluids and trapped matter waves. For anyone who got lost around ‘soliton’, rest assured it involves the use of lasers. Obviously.

Numberphile filmmaker and general internet legend Brady Haran has been busy putting together a series of YouTube videos about the Rubik’s cube, with contributions from Aperiodical friends Matt Parker and James Grime. The videos also feature lots of solving clips sent in by viewers, and Aperiodical Editor triumvir and sometime maths-talker-abouter Katie Steckles (that’s me) occasionally pops in to make comments and state facts which are no longer true (a world record was broken 4 days after filming).
