Our understanding of the structure of matter was revolutionized in 1964 when American physicist, Murray Gell - Mann, proposed that a category of particles known as baryons, which includes protons and neutrons, are composed of three fractionally charged objects called quarks, and that another category, mesons, are formed of quark - antiquark pairs.
