The GoW came across the Gresham College YouTube channel earlier today, featuring some interesting clips from a lecture by cosmologist and Gresham College Geometry professor, John Barrow, on everyday maths.
The Gresham College is a venerable London institution devoted to providing free lectures and events for the public, in the best of traditions.
In the clip below, Barrow shows the maths behind bank numbers and what’s known as the ‘Luhn Test’.
View Barrow’s introduction to the lecture, and clips about the mathematical patterns behind everything – post codes, six degrees of separation, mobile phone IMEI numbers and all sorts of other things.
