permutation
There are many errors that can occur when numbers are written, printed or transferred in any manner. Luckily, there are schemes in place to detect, and in some cases even correct, such errors almost immediately. Emily Dixon takes a break and discovers that codes are not just for sleuths.
Levitation, magical weight loss and perpetual motion — these are just some of the tricks that have been attributed to things that spin. So do gyroscopes need their very own version of physics? Hugh Hunt debunks some myths.
With the credit crunch dominating the news, columnists have been wailing about "chaos in the markets", and "turbulent" share prices. But what does move the markets? Are they deterministic, or a result of chance? Colva Roney-Dougal explores the maths, from chaos to group theory.
