Quarks comprise one of two classes of the fundamental particles. Quarks possess fractional electric charges and are not observed in free state. The word 'quark' first appears in James Joyce's Finnegans Wake and has been chosen by Murray Gell-Mann as a name for fundamental building blocks of particles.
