Having done such an excellent job so far this summer, the Millennium Mathematics Project is continuing its coverage from a mathematical angle, with the Plus Paralympic calendar and the special project Maths and Sport: Countdown to the Games. For example, John Barrow discovers when investigating the different speeds of races over different distances that wheelchair racing is “not just a wheel-based equivalent of Olympic racing” but is quite a different kettle of fish.
