'''Quarks''' are [[elementary particle]]s that are one of the two types of [[fermion]]s, the other being [[lepton]]s. Quarks are the only elementary particles that interact in all four [[fundamental interactions]] of physics. There are six [[flavor]]s of quarks: up, down, strange, charm, bottom, and top quarks. The [[antiparticle]]s of quarks are called [[antiquark]]s. Quarks have [[spin]] 1/2, [[baryon number]] 1/3, and electric charge 1/3 or −2/3. Properties and [[quantum number]]s usually can be found by direct experimenting but [[confinement]] of quarks stops any chance of precise measurement.
The word ''quark'' originates from the passage "Three quarks for Muster Mark!/Sure he hasn't got much of a bark/And sure any he has it's all beside the mark." from ''[[Finnegans Wake]]'' by [[James Joyce]].
