Here’s a round-up of some news from the last couple of months.

The Magic Theorem
Back in 2008, Chaim Goodman-Strauss and Heidi Burgel, together with the late John Conway, wrote a book called The Symmetries of Things, which covered a range of topics around mathematical symmetry and the symmetries of geometric objects.
Now the first two authors have a new book, The Magic Theorem, due for publication this week. We spoke to Heidi and Chaim about where this book has come from and what it’s about.
Mathematical Objects: Aperiodic monotile with Chaim Goodman-Strauss

A conversation about mathematics inspired by the new aperiodic monotile. Presented by Katie Steckles and Peter Rowlett, with special guest Chaim Goodman-Strauss.
The paper announcing the discovery is An aperiodic monotile by David Smith, Joseph Samuel Myers, Craig S. Kaplan and Chaim Goodman-Strauss.
Chaim was recording from MoMath in New York, which will be running a creative artwork competition based on the monotile with UKMT. Chaim also mentioned a meeting in Oxford: Hatfest: celebrating the discovery of an Aperiodic Monotile.
Note: This podcast was recorded after the discovery of the ‘hat’ and ‘turtle’ monotiles but before the announcement of the ‘spectre’ monotile. Confused? Don’t worry, we explain in the episode!

Now that’s what I call an aperiodic monotile!

Surely you didn’t expect news about aperiodic tilings to appear at regular intervals? You know how it is – you wait ages for a new aperiodic monotile discovery to come along, then two come in quick succession.
In March, we covered the discovery of an aperiodic monotile. The team of authors behind that discovery have been continuing their work and this week have an even bigger announcement.
An aperiodic monotile exists!

Actual aperiodicity news on The Aperiodical!
This is probably the biggest aperiodicity news we’ll ever cover here: David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss have produced a single shape which tiles the plane, and can’t be arranged to have translational symmetry.
And it’s so simple!
Podcasts for a university mathematics student
Yesterday, I was asked by Mariana Farinha for podcasts I would recommend to a college student of Mathematics. I assume this is college in the American sense, i.e. university. Though targetting an audience is usually a broad business, so with a suitable margin of error I replied with a few, retweeted the request and a few others replied. Here are the suggestions. What would you recommend? Leave a comment!
