EVERY so often a discovery is made which piques the public’s interest in science once more. A single proof captures the imagination by the significance and the scale of the advance. This week’s news that physicists had proved with near certainty the existence of the Higgs boson is such a point in the history of science.
The scale of the experiment matches the scale of the intellectual leap achieved. A huge apparatus, 27 kilometres in circumference, buried 100 metres below the French-Swiss border near Geneva, accelerated particles in a near-perfect vacuum to speeds just below that of light and measured the effect of their collisions. Minute variations in energy released prove the existence of the Higgs boson, which had been postulated in theory by Peter Higgs in 1964 to explain the mass of elementary particles. Continue reading
