## history of mathematics

**Chris Hollings**reveals that our number system, much used but rarely praised, is in fact a work of genius and took millennia to evolve.

**Richard Elwes**explores how these questions brought triumph to one man and ruin to another, ventures to the limits of mathematics and finds that, with infinity, you're spoilt for choice.

**Peter Macgregor**explores the beautiful world of the infinite.
