If you're wondering how to feed your maths habit between the 8th and 21st of March, then why not head to Cambridge for the 2010 Cambridge Science Festival? There'll be plenty of free maths events, including:

• IMAGINARY: through the eyes of mathematics — A travelling exhibition of beautiful mathematical images and artwork taken from algebraic geometry and differential geometry in which visitors are able to create their own mathematical art. Age range: 12+.
• Conversations across science and art — A talk and discussion event centred on the relationship between science and art, including the presentation Every picture tells a story by Professor John D Barrow and a talk by Professor Gerry Gilmore exploring the relationship between art and astronomy. Age range: 14+.
• Enigma: codes and codebreaking — The Enigma cipher was one of the most powerful weapons of the Second World War. An apparently unbreakable code. How did a small group of mathematicians crack it? Come and see a demonstration of a genuine Enigma machine, and try your hand at breaking different codes used through 2500 years of history! Age range: 8+.
• Who Wants To Be a Mathionaire? — Explore the maths of probability, chance and uncertainty in this exciting and highly interactive game-show style quiz, using hand-held voting technology to answer against the clock! Age range: 14+.
• The Maths and Physics of Sport — Professor John D Barrow looks at some applications of physics and simple mathematics to a variety of sports, including weightlifting, rowing, throwing, jumping, drag car racing, balance sports, and track athletics, as well as some of the paradoxical systems of judging used in ice skating, and the effects of latitude and air resistance on some performances. Age range: 14+.
• What's the risk of getting out of bed? — We are constantly being exhorted to change our behaviour to reduce the chances that things will turn out badly for us, and government is continually intervening to make our society safer. But are we being too cautious? In this lecture, Professor David Spiegelhalter will look at attempts to measure and communicate the benefits, and possible harms, of risk reduction in a range of areas, from swine flu to climate change, heroin to hang-gliding. Age range: 14+.
• The hands on maths fair — Games and puzzles for all ages from the University's Millennium Mathematics Project. Pit your wits against the SOMA cube, tangrams, Auntie's Tea Cups or giant dominoes, and sharpen your strategic reasoning skills! Age range: 5+.
