From James Joyce's book Finnegan's Wake from the line "three quarks for muster mark"
BTW, Quark is a German cheese. It is kinda like pureed cottage cheese with a little sour cream added. I like it.
The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964.
The reason that protons are positive and neutrons have no charge is owed to the fact that quarks, which make up these particles, do not have integral charge. The charge of an up quark is +2/3, and the charge of a down quark is -1/3. When the charges of the quarks are added for the particles, we get the following: Proton = up quark + up quark + down quark = 2/3 + 2/3 - 1/3 = 4/3 - 1/3 = 3/3 = +1 Neutron = up quark + down quark + down quark = 2/3 - 1/3 - 1/3 = 2/3 - 2/3 = 0 (zero)
A quark is the smallest particle in matter.
A proton can be divided into 2 Ups and a Down quark, and a neutron into 2 Downs and an Up quark. In general the quark is the elementary particle from which protons and neutron are formed.
All matter to our understanding is made of very small things called atoms. These are neutral in charge with a nucleus containing protons and neutrons and outside there is electrons. These particles can further be split into things such as quarks. There includes many types of these and are strange quark, up quark, down quark, charm quark, bottom quark, and top quark. These all have values associated with them such as spin and charge.

Quark
According to wiki, quark was once called as the 'parton', a term coined by Richard Feynman. At present, the word 'parton' is used as a collective term for the constituents of hadrons.
An anti-strange quark is an antiquark corresponding to the strange quark.
An anti-up quark is an antiquark which corresponds to the up quark.
An anti-beauty quark is an obsolete term for the anti-bottom quark.
What about a Quark? or if you allow slang, a quake.
