Tom Rocks Maths returns for a 3rd season on Oxide Radio with the usual eclectic mix of rock music and maths. This time I’m joined by Joshua – one of my second year students at St Edmund Hall – who brings along an amazing puzzle involving square numbers and explains the magic of Fourier Series, as well as taking part in the usual guest numbers quiz. Plus, music from Blink 182, Bring Me The Horizon, Sum 41 and an ABBA cover (Joshua’s choice)… This is maths, but not as you know it.
