"Codes" and "Simulating the world" are the subjects of this year's popular lectures from the London Mathematical Society. The first, which will be given by Professor Peter Cameron, will show there is a code that does jobs ranging from catching out a liar to sequencing the human genome to designing a quantum computer. At the second, Professor Chris Budd will demonstrate how maths helps us to drive a supersonic racing car, make dinosaurs live again, or leave the solar system, without moving from our desks.

It allows participants to experience maths through sight, sound, touch and movement. Given sufficient space and help, there is no limit to the number which can be accommodated. Fee for a typical five-day event inclusive of transport costs, accommodation, printing, postage and packing is pound;750. Two events can run in parallel with the second being led by a host already familiar with the apparatus. Should the Circus be booked up for the period required, Magic Maths Boxes can be hired. The weekly hire rate for an exhibition which could accommodate 60 children at a time is pound;750. Paul Stephenson, Old Coach House, Penypwllau, Holywell, Flintshire CH8 8HB. Tel: 01352 713014.
