• Comments on our last episode
• Weinstein-gate: full coverage via [twit handle = “peterrowlett”] (Peter Rowlett in real life) at the Aperiodical
• A boy called Tutankhamun: Owen Daniel’s TEDx talk, a variation on the Tuesday’s Child problem ((Colin referred to a quote that was neither Bohr or anyone like that, but Asimov: “The most exciting phrase to hear in science, the one that heralds new discoveries, is not “Eureka!” (I found it!) but “that’s funny…””))
• Making your cousin cry while playing Monopoly and Pascal’s tetrahedron
• Coca-Cola names, ways of saying “unpopular” and Irn-Bru
• Scone news! First from Dr Eugenia Cheng and then the brilliantly-named sconic sections
• Google’s dictionary of numbers and listening to the budget and XKCD
• Colin becoming a flash-in-the-pan celebrity thanks to this article, and stealing Dave’s thunder on the chi-squared test.
• Dave’s puzzle from last time. A much better explanation after Dave’s garbled attempt: Hexagon Puzzle solution
• Colin’s puzzle for this time: You have ten identical balls at one end of a smooth horizontal ((not stated in the podcast, but assumed)) track, and ten identical balls at the other.

• What Colin doesn’t understand: how to calculate $\pi$
• A long and rambling ending…
