Wrong, But Useful: Episode 64

Play

In this month’s episode of Wrong, But Useful, we’re joined by @DrSmokyFurby and his handler, Belgin Seymenoglu.

Apologies for the poor audio quality on this call. Dave's fault, obviously1 .

We discuss:

  • The Talkdust podcast
  • (via Adam Atkinson): Life insurance
  • Superpermutations: new record for n = 7 in the comments on a YouTube post
  • @pecnut and @mscroggs have a LaTeX package that puts hats on things
  • Desmos adding support for distributions and all sorts
  • @mdawesmdawes’s QUIBANS website
  • Dave has been playing the game The Mind
  • (Via @peterrowlett), 318,000 combinations of pringles
  • Dave gave a talk in Exeter and will hopefully give one in Bristol in June.
  • Humble Pi by @standupmaths - book launch on March 2nd in London, tickets selling fast sold out. You can join the waiting list here.
  • @honeypisquared (Lucy)’s new podcast - Mathematips
  • We’ve been shouted out in @aap03102 (Chris Smith)’s newsletter, and on @missradders's padlet – thanks!
  • Tax - round up or not?
  • Rotationally symmetric equations (@robeastaway and @peterrowlett): here, here, and Elliot’s versions here
  • Puzzle feedback from last time: Gold star for @chrishazell72: for showing that $(a-b)^2 + (b-c)^2 + (c-a)^2 + (a+b+c)^2 = 3(a^2 +b^2 + c^2)$, and that the first child is 6, younger (2yo) born when elder was 3.
  • New Puzzle (via @cmonMattTHINK): Find the line that touches $y= x^4 - x^3$ at two distinct points. Avoid calculus if possible.

* Edited 2019-02-13 to fix the title. Thanks, Adam.
