There are a small number of universal human languages which are very widely understood. English itself is one, the arts are another, there is sport - especially football - and there is science.

On 4 July the CERN institute announced a discovery that would put an end to something that has been bugging scientists for a while; enough to warrant a five-decade search, millions of man hours and billions of euros worth of support. Their struggle not only resolves one of science's most elusive mysteries, but also contains important lessons on how Europe can shake off its economic lethargy.
Yesterday was, for many physicists (and physics students), as a friend put it, "a bit like Christmas", and I think it is safe to bet that quite a few at CERN woke up today with a very Christmassy hangover. But, now that the party is over, a question arises (as often on the morning after): what exactly did happen yesterday?
