From airline tickets to ordcers and deliveries, simple maths is behind the codes hidden behind our everyday lives. At the centre of this are 'check codes' that ensure that a mistake have not been made.

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 maths behind this piece of code we find in our everyday lives.

This is the 7th 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:

Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.
