Measurement is a tricky business, and rarely leaves the thing measured unchanged, as Heisenberg's Uncertainty Principle states at the quantum level. But statistician David Hand has gone back to the foundations, examining measurement right across the various disciplines: psychology, medicine, physical sciences, economics, the social sciences and elsewhere. He must treat in a unified manner scales used to measure phenomena as different as pain, retail prices and magnetism.
Statisticians welcome a call to make official statistics independent - but can it really be done in one hour?
Mathematician and physicist John Baez declares himself fascinated by exceptions in mathematics. This interest has led him to study the octonions, and, through them, to find out more about the origins of complex numbers and quaternions. In the first of two articles, he talks about connections between algebra and geometry, and the importance of lateral thinking in mathematics.
Francesca Harris has always known she wanted to work in the music or film industry, and she has found that her maths skills have stood her in good stead as she works her way up.
It feels like we've always known that the universe began with a Big Bang, and like the Big Bang could never have been called anything else.
