Quarks Quarks are mavin and only(a) of six hypothetical particles that are believed to watch the basic pieces of the elementary particles called hadrons. Hadrons are the proton, neutron, and pion. The quark concept was proposed in 1963 by two diametrical researchers, American physicists Murray Gell-Mann and George Zweig. The term quark was taken from Irish writer James Joyce’s Finnegan’s Wake. At first quarks were classified as three opposite kinds: up, down, and strange. The proton, for example is believed to be constituted of two up quarks and one down quark.
Later theorists came up with a fourth quark. In 1974 the fourth quark named “charm” was experimentally confirmed. Therefore a fifth and sixth quark called bottom and top, were hypothesized for symmetry reasons. experimental evidence for the bottom quark was obtained in 1977. The top quark wasn’t confirmed till 1995, when two teams of physicists announced they had pin down and measured the to...If you want to get a full essay, maintain it on our website:
