Yep. Did anyone see Go Forth & Multiply with Alan Davies and that maths whizz early this year?
It explained The Monty Hall Problem (which I try to do everytime I meet someone new and get drunk, as probability goes this is really, really awesome) and also what the shape of the universe is most likely to be. It also goes into 4th dimensions.
Anyway, I just discovered it's on youtube. Happiness ensues.
I wish more TV was like this.
