antimatter

If you have any sense you will join Andy tomorrow evening (Weds 26th) in Clyne, where he will be testing the contributory effects of gravitational waves and rapid deceleration forces on the shear-stress properties of aluminium alloy: http://www.mtbpigs.co.uk/forum/index.php?topic=2742.msg28070

However, of you want an evening of nerd-based sciency fun without the adrenaline, mud and crashes then you might be interested in this instead:

Antimatter – Science and Applications

Prof Mike Charlton (Swansea University)
Wednesday 26th November 2014 at 7:30pm

Antimatter was discovered in the 1930’s and since then positrons have found numerous applications in atomic and materials science, engineering and medicine. More recently, physicists, including the speaker, working at CERN have learnt how to create and capture atoms of antihydrogen. A few of these anti-atoms have been held for periods longer than 15 minutes and the first experiments have been performed to measure their properties. The talk will cover the history of antimatter, why the positron is so useful and the current anti-atom experiments and the motivation for undertaking them. The latter will involve one of nature’s great conundrums: the absence of bulk antimatter in the current epoch of the Universe.

I shall probably be attending the latter.  ::)
