# Wrong, But Useful: Episode 10

/podcasts/wbu10.mp3

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 [twit handle = “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 [twit handle = “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: [twit handle = “slsingh”]’s
*The Simpsons and their Mathematical Secrets*, and Colin’s: Two Girls, One On Each Knee by [twit handle = “alanconnor”] - The numerology of the calendar, 11/12/[20]13 and [twit handle = “andrew_taylor”]’s brilliant [twit handle = “823years”] account
- [twit handle = “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
