Aperiodical Round Up 10: a rathole down which valuable mathematical effort is being poured
Ten! TEN! TEN! Incredible. David Cushing asked me a very good question once: what have you done between five and ten times (inclusive)? Well, this is the last time ‘Writing an Aperiodical Round Up’ will be in the same category as ‘getting a new wallet’ and ‘saying hello to Peter Beardsley’.

Podcasts for a university mathematics student
Yesterday, I was asked by Mariana Farinha for podcasts I would recommend to a college student of Mathematics. I assume this is college in the American sense, i.e. university.

Matt Parker talks percentages
If anyone caught BBC1’s consumer moanfest Watchdog this week, they may have been pleasantly surprised to see Aperiodicobber ((The internet assures me that ‘cobber’ is Australian slang for ‘friend’.)) Matt Parker featured in the show. Following a segment about a UK sports chain and its shocking use of the classic ‘UP TO 70% OFF’ ruse, they invited Matt on the show to explain how to calculate percentages more easily, and so that Anne Robinson could mock him for being Australian, apparently.
Since the tips Matt presented were useful, we at the Aperiodical thought it was worth reproducing Parker’s Patented Percentage Ploys here, for your reference.
