# 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)
• 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

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.
