As you may have read in this previous blogpost, on 9th March 2012 I took part in the Ig Nobel Prizes Uk Tour by speaking at Imperial College in the 800-seater Great Hall of the Sherfield Building. The event was completely sold out. The speakers included Oxford University mathematician Dr Mason Porter discussing his paper on synchronisation in cows, Ig Nobel winner Mirjam Tuk on her paper that explores improved decision-making when you have a full bladder, New Scientist magazine's John Hoyland with some extracts from its ever-excellent Feedback pages, and myself talking about how police officers once used a form of cryptic hide-and-seek during the 'dead' hours on night duty (between 3am and 5am) as a memory aid to learning the fastest routes to various locations. As a bonus we had Professor Andrew George from Imperial reading some terrible poetry by William Topaz McGonagall. A tremendously fun evening hosted brilliantly by Marc Abrahams, founder of the Ig Nobels and the Annals of Improbable Research. And now you can see it (I'm on at 48 minutes in).
