The Search for Quark :: essays research papers

What exactly is Quark? Quark a fermion which is believed to be one of the fundamental constituents of matter. All quarks affirm a fractional galvanic charge1. This pretty much means quarks have spin (rotate two bounteous rotations to get to place it started), apply to Pauli Exclusion Principle, is one of the things that make up tout ensemble matter, and its electric charge is a fraction. There are triad different colors of quark red, green, and blue. The colors always up to white. in addition there are three different kinds of antiquark cyan, yellow, and magenta. Quarks are at least 330MeV. Quarks were first proposed in 1964. It was named quark by Caltech theorist Murray Gell-Mann. He named them that from a quotation in a novel Three quarks for Muster Mark, authentic he hasnt got much of a bark 2 Gell-Mann express all mesons, baryons, and hadrons are made of quarks. He also said they are made of three types of quarks (up, down, and strange). That makes a total of nine type s of quarks. George Zweig called them aces. Not galore(postnominal) people believed in it at this time. From 1968 to 1973 MIT bombarded protons and neutrons with electrons. Electrons ricocheted off protons and neutrons as if it hit a hard, tiny object. The hard object was a quark. Over the years experiments and researches have led to a solidification of indirect evidence that quarks exist. Despite all this indirect evidence they could not find a single part with quark. No fraction detector detected one. This led to a lot of non believers. As more proof has been shown that quarks exist it became more popular and little doubted.Chapter 1 Over coming SkepticismDoubters did not believe in quarks. They thought of quarks just as a math equation that could exempt a couple of things. They had good reason. The quark was never found tolerant or even revealed itself. That was until 1974 when two discoveries occurred at the Brookhaven Laboratory and Stanford. They had found a bare-ass p article. Stanford called it the psi and Brookhaven called it the J. The new particle had to be a new kind of quark. Two years later Harvard theorist Sheldon Glashow named the new particle the charmed quark. This discovery shattered any doubts about the quark macrocosm real or not. The discovery also shattered the bootstrap stick theory. This theory said that protons, neutrons, and other particles were the smallest units.
