Quarks Essay
Physicists are always looking for particles too small to be seen by the human eye. In one such search 'cosmic' rays were discovered using a cloud chamber experiment. These perviously undetected rays contained many elementary particles. The newly encountered particles were found to combine to make sub-atomic particles, that were later divided into groups classified as bayons, mesons, leptons and bosons. Leptons include the electron and neutrino, bosons include protons and neutrons. Most of the new particles were bosons. The bosons all had similar properties which were grouped into a system called the eightfold way. Physicists began to wonder if the behaviour of these new particles were determined by smaller particles within. These theoretical particles were named quarks. The name quark was a nonsense name taken from a phrase in a book. There are six known types of quarks, called flavours. These flavours are grouped into pairs; up / down, strange/ charmed, top / bottom (sometimes beauty / truth). Each quark also has a corresponding anti-quark. Because the charge of quarks is only a fraction they are never found alone. The first pair
