Wrong, But Useful: Episode 10

This month, @reflectivemaths (Dave Gale in real life) and I discuss:

  • The birth of baby Bill (d'aww)
  • Dave's loyalty to More or Less, and nappies
  • WBU ultra-loyalist @srcav's comments on Episode 9 and a plea for reviews
  • Whether to up our podcasting output in an attempt to outdo Math/Maths and TES Maths
  • Congratulations to @peterrowlett on his (provisional) doctorate [UPDATE: Peter, dammit, is a doctor, not a mathematician; his Ph.D. is in Computing and Maths Education.]
  • Dave's Christmas present: @slsingh's The Simpsons and their Mathematical Secrets, and Colin's: Two Girls, One On Each Knee by @alanconnor
  • The numerology of the calendar, 11/12/[20]13 and @andrew_taylor's brilliant @823years account
  • @perspective_pick's run-in with the Maths Police and other things that have got our goat
  • The Nix The Tricks ebook (review here)
  • Vedic Mathematics, which doesn't get a link because it's dreadful
  • Dave's plans for a book of puzzles and whether there's anything new under the sum
  • World record attempts involved cards, dates, coin towers and chess sets (Colin's attempt here)
  • Colin's alternative quadratic method, revisited - explained more clearly here.
  • Colin's geometry puzzle: inscribe a square inside a circle of radius $r$; inscribe a square inside a semicircle of radius $r$; what's the ratio of their areas?
  • Colin doesn't understand calculus of variations and hopes it will make him better at Real Racing

* Updated 7/1/2014 to clarify Peter's qualification.


Colin is a Weymouth maths tutor, author of several Maths For Dummies books and A-level maths guides. He started Flying Colours Maths in 2008. He lives with an espresso pot and nothing to prove.

Where do you teach?

I teach in my home in Abbotsbury Road, Weymouth.

It's a 15-minute walk from Weymouth station, and it's on bus routes 3, 8 and X53. On-road parking is available nearby.
