Here’s another episode of our irregular podcast about what’s been happening on the site.

This time, we talked about:

- Advances in pure nonsense
- Robert Schneider, Mathematical Musician/Musical Mathematician
- #MTT2K: Teachers critique Khan Academy
- Surds: what are they good for?
- Calculus of the Nervous System
- The new fonts on the site
- Christian’s new Aperiodical Round Up and Interesting Esoterica Summation
- Puzzlebomb October 2012

Christian apologises for the poor sound quality, an unavoidable consequence of being at the family home for the weekend without a proper microphone.

As always, we’re keen to hear about your mathematical exploits either by email at root@aperiodical.com, our twitter @aperiodical, or whatever means you can think of to get in contact with us.

Your title font is Concrete Roman, which was designed for the book Concrete Mathematics (Graham, Knuth, Patashnik). The preface explains that Concrete is both the opposite of Abstract, and also a blend of Continuous and Discrete.

Top knowledge! Thanks.
