News from the world of Maths
How many people died? It's one of the first questions asked in a war or violent conflict, but it's one of the hardest to answer. In the chaos of war many deaths go unrecorded and all sides have an interest in distorting the figures. The best we can do is come up with estimates, but the trouble is that different statistical methods for doing this can produce vastly different results . So how do we know how different methods compare?
From jelly fish, to biomass, to topology and speeding neutrinos, we've had a busy first two days at the AAAS meeting in Vancouver.
Yesterday's refusal by the UK government to posthumously pardon Alan Turing makes sad news for maths, computer science and the fight against discrimination. But even if symbolic gestures are, symbolically, being rebuffed, at least Turing's most important legacy — the scientific one — is going stronger than ever. An example is this week's announcement that scientists have devised a biological computer, based on an idea first described by Turing in the 1930s.

How does Olympic success correlate with a nation's GNP? How does the location of the Olympics affect the chance of record breaking? How can simple statistics help us understand the likelihood of winning streaks and the chance that an innocent athlete will fail a drugs test? What events should an ambitious nation target as the "easiest" in which to win Olympic medals. John D. Barrow will explore these question and more in a free public lecture at Gresham College in London tomorrow, 17th January 2012.
