It’s your annual Wrong But Useful Big MathsJam Special! Recorded live, so the audio is a bit shaky in parts.

  1. @icecolbeveridge, @reflectivemaths and @peterrowlett discuss Tantrix with some excited background chatter
  2. Colin interviews @teakayb (Tom Briggs in real life), who’s at MathsJam with an Enigma machine
  3. @pecnut and @mscroggs (Adam and Matthew) tell Colin about @chalkdustmag
  4. Dave and Colin review the whole shebang
  5. @sparksmaths (Ben Sparks) talks about his musical MathsJam experience
  6. A round table with Peter, Dave, @dragon_dodo (Dominika Vasilkova), @mikegibson2010 (Michael Gibson) and an audience of hundreds.

Puzzles mentioned:

  • Find three rational squares in arithmetic series with common difference of 5 (@kshancock)
  • Find $n$ such that $\frac{(1!)(2!)(3!)…(99!)(100!)}{n!}$ is square (@tombutton)

* Special thanks to @colinthemathmo and @stecks for all the work they do to make Big MathsJam such an amazing weekend. I had a blast.
