Simple mathematics is all around us in our everyday lives. In the case of codes, the simple pure mathematics behind it is fascinating and surprising. 

In this extract from his lecture on 'Codebreaking in Everyday Life', John D. Barrow, Gresham Professor of Geometry and Professor of Mathematical Science at the University of Cambridge, explains the background to the maths behind the pieces of code we find in our everyday lives.

This is the 1st part of 'Codebreaking in Everday Life'.
The full lecture is available (in 13 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats:
