The term ‘Quark’ for the fundamental particles that make up protons and neutrons was coined by American physicist Murray Gell-Mann in 1964. He proposed the quark model independently of George Zweig, who had called the particles “aces”. Gell-Mann chose the name “quark” from James Joyce’s novel “Finnegans Wake”.

Murray Gell-Mann proposed the quark model and named these fundamental particles ‘quarks’.

Protons and neutrons are baryons, which are composed of three quarks. For example, a proton is made of two up quarks and one down quark (uud), and a neutron is made of one up quark and two down quarks (udd).
