What People Think About

The Code Book on CD-ROM

"It is a fascinating CD-ROM, and I can see how one could get obsessed with the subject!"

Arthur C. Clarke

“I never thought that I would see a group of lower set Year 7 pupils so engrossed in mathematics that they forgot to go to lunch!”

Vicki Addey,
Head of Mathematics,

Norman Court Prep School.

“The pupils have great fun with the interactive coding simulators, which range from simple codes to the Enigma.”

Sue Johnston-Wilder

Centre for Mathematics Education,
Open University

"The CD is packed with material for cross curricular use in schools. Get interactive with an Enigma machine and marvel at its complexity and the brilliant minds of the people who changed the course of history. See how prime numbers provide the security for the thousands of financial transactions taking place on the Internet every second. Students in my school have set up a link with counterparts in Barcelona. They send and receive coded messages, crack and translate before solving the mathematics problems contained. "
