This post is both a video and text. The content is largely the same in both versions, so you can pick one to look at. I’d like to show you a puzzle, or game for one person, that Ed Kirkby came up with. Ed showed this to me at the Big MathsJam gathering last year.…
Since it’s the time of year when you might be looking for mathematical gifts to buy for your friends, colleagues and loves ones, I thought I’d share some recommendations and suggestions for places to find gifts online.
Here’s a selection of mathematical news from the month of November that we didn’t otherwise mention on the site. Proof News The dream team of Tim Gowers, Ben Green, Freddie Manners and Terence Tao (pictured above) claim to have solved the polynomial Freiman-Ruzsa conjecture (originally conjectured by Hungarian mathematician Katalin Marton), which is described by…
The next issue of the Carnival of Mathematics, rounding up blog posts from the month of November 2023, is now online at John D Cook’s blog. The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.
In this series of posts, we’ll be featuring mathematical video and streaming channels from all over the internet, by speaking to the creators of the channel and asking them about what they do. We spoke to Bernhard Werner, who’s recently started a YouTube channel called Sum and Product to share mathematical visualisations and explanations.
In the last Finite Group livestream, Katie told us about emirps. If a number p is prime, and reversing its digits is also prime, the reversal is an emirp (‘prime’ backwards, geddit?). For example, 13, 3541 and 9999713 are prime. Reversing their digits we get the primes 31, 1453 and 3179999, so these are all…
At this year’s MathsJam UK Gathering, I had the pleasure of running one of the Saturday Night Tables – a chance to invite attendees at the Gathering to drop by and play with something. Together with fellow Manchester MathsJam regular Andrew Taylor, I ran a table of Mathematical Drawing Hacks – ways to make drawing…
