Wrong, But Useful: Episode 59
podcasts/wbu59.mp3
In Episode 59 of Wrong, But Useful, we’re joined by @el_timbre, who is Emma Bell in real life.
We discuss:

Emma’s Roots column in Chalkdust ((a magazine for the mathematically curious))

Number of the podcast: 64, because it’s pleasing, and Dave sings the 64 Zoo Lane theme, which is less so.
 Emma’s hexastix construction and the maths behind it.
 Dave has been playing Trivia Mixup. So have we now. Apparently, 47 is the most random number.
 Dave wants to know what people should know.
 Emma runs the #mathsmatters hashtag, trying to enthuse and engage people in maths
 @nira_ch (Nira Chamberlain) won the Aperiodical MathsOff. Dave claims to be the nice one but then fails to plug Colin’s books in Swedish.
 There were some Fields Medals. Caucher Birkar had his stolen and replaced. We ponder the logistics of getting him a replacement, much more than what he won it for.
 @mscroggs has LOOPed up Mathsteriods
 A lovely proof of the sum of squares.
 Puzzle feedback: Gold stars for @alephthought and Sam Steele who each worked out that 40 cows would last ten days, and 10 cows could survive forever.
 This month’s puzzle: Aloysius and Beatrice are flipping coins. Aloysius flips until he gets two tails in a row; Beatrice until she gets a head then a tail. How many flips, on average, does each player take?
