* Order and chaos in action and tangent circles will be explored by Dr Frank Berkshire, Imperial College, London University, and professor Caroline Series, Warwick University, at The London Mathematical Society's free 1999 popular lectures. They will show how objects like to float, tennis racquets spin and polyhedral dice come to rest and how "patterns of tangent circles have led to geometrical problems from ancient Greece to old Japan, but the full solution is a wonderful 20th-century idea".
