This involved complex packing and storage of protons and antiprotons circulating in a vacuum chamber.The first intensified collisions in the CERN super-accelerator were observed in 1981.The background to their discovery was the development by physicists of a theory known as the “standard model”.A key feature of the model is that all the forces of nature involve the exchange of subatomic particles called gauge bosons.The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.

This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.It was first described in the 1930s by Enrico Fermi, but until van der Meer and Rubbia detected the W and Z particles there was no observational evidence for their existence.The two men were physicists at CERN (the European Organisation for Nuclear Research) near Geneva where, from the 1950s, scientists had been engaged in developing sophisticated “atom-smashers” to study the high-speed collisions of small particles of matter – a process likened to firing two Swiss watches into each other and deducing how they work by examining their debris.
