The Gresham Professor of Geometry, Professor Sir Roger Penrose FRS OM is giving a free public lecture in London on this topic next month:
"Games and Numbers"
Certain very simple-looking but tantalising and amusing games, such as the games of 'nim' and 'sprouts', illustrate mathematical principles of wide application. This also leads to definitions of kinds of number that include both the infinitely large and the infinitely small, according to a scheme put forward by the mathematician J H Conway.
Tuesday 21 November 5.30pm
This lecture will be held at St Paul's Girls' School, Brook Green, London W6
