"I remember being at the final congressional hearing in 1994 to decide whether the US government would fund the building of an atom smasher outside Dallas that would be twice the size of that at Cern, Geneva," he says. "A physicist was asked, 'Will we find God?'. The reply came back, 'We will find the Higgs Boson [sub-atomic particle].' That answer cost US physics the £12bn project."Thinking back, I would have said, 'This machine will take us as close as humanly possible to his or her greatest creation - genesis itself. It will give us a window on the instant of creation.' Before 1990, physicists only had to say 'Russia' to get their hands on cash, but since the end of the cold war, we have had to learn the language of the taxpayer."
