Physics seeks the future

AWISE PROVERB(LHC suggests not putting all your eggs in one basket. Over recent decades, however, physicists have failed to follow that wisdom. The 20th century—and, indeed, the 19th before it—were periods of triumph for them. They transformed understanding of the material universe and thus people’s ability to manipulate the world around them. Modernity could not exist without the knowledge won by physicists over those two centuries.In exchange, the world has given them expensive toys to play with. The most recent of these, the Large Hadron Collider ), which occupies a 27km-circumference tunnel near Geneva and cost $6bn, opened for business in 2008. It quickly found a long-predicted elementary particle, the Higgs boson, that was a hangover from calculations done in the 1960s. It then embarked on its real purpose, to search for a phenomenon called Supersymmetry.
