Mathematics and the future of transport - Véronique Pagé talks to transport mathematician John Hammersley. John talks about a new type of transportation system, Personal Rapid Transit, and explains how mathematical models are being used in its development.

Mathematical histories - Peter Rowett describes some of the ciphers used by ancient and medieval cryptographers, and shows how to go about breaking them.
