The quark model was independently proposed by physicists Murray Gell-Man and George Zweig in 1964. Gell-Mann originally named the quark after the sound made by ducks. For some time, he was undecided on an actual spelling for the term he intended to coin, until he found the word quark in James Joyce's book, Finnegan's Wake
Three quarks for Muster Mark!
Sure he has not got much of a bark
And sure any he has it's all beside the mark.
-James Joyce, Finnegans Wake
Gell-Mann went into further detail regarding the name of the quark in his book The Quark and the Jaguar:
In 1963, when I assigned the name "quark" to the fundamental constituents of the nucleon, I had the sound first, without the spelling, which could have been "kwork". Then, in one of my occasional perusals of Finnegans Wake, by James Joyce, I came across the word "quark" in the phrase "Three quarks for Muster Mark". Since "quark" (meaning, for one thing, the cry of the gull) was clearly intended to rhyme with "Mark", as well as "bark" and other such words, I had to find an excuse to pronounce it as "kwork". But the book represents the dream of a publican named Humphrey Chimpden Earwicker. Words in the text are typically drawn from several sources at once, like the "portmanteau" words in "Through the Looking-Glass". From time to time, phrases occur in the book that are partially determined by calls for drinks at the bar. I argued, therefore, that perhaps one of the multiple sources of the cry "Three quarks for Muster Mark" might be "Three quarts for Mister Mark", in which case the pronunciation "kwork" would not be totally unjustified. In any case, the number three fitted perfectly the way quarks occur in nature.
- From Wikipedia.com
There are 6 'normal' quarks in total.
First Generation:
- Up Quark
- Down Quark
Second Genaration:
- Strange Quark
- Charm Quark
Third Generation:
- Bottom Quark
- Top Quark
All of these Quarks have anti-particles like the Antidown Quark.
arbitrary naming
Protons and neutrons are composite particles make up of up and down quarks. There are two up quarks and one down quark in a proton, and two down quarks and an up quark in a neutron.
There are 6 different types of quarks, named in pairs:Top, BottomStrange, CharmUp, Down0123qwerty0123But don't forget that all particles, besides force particles ( gravity-graviton, electromagnetism-photon, weak force-low guage boson, strong force-gluon ), have antimatter counterparts.Anti-top, Anti-bottomAnti-strange, Anti-charmAnti-up, Anti-down
Since all protons and neutrons are made of quarks and they have mass, quarks must have mass (in fact they do).
While there are some hypothesis that quarks might be made up of smaller particles, there is no general consensus on this topic.
Quarks can actually vary greatly in size. The most common types of Quarks are Up and Down (scientists are not the most creative when it comes to names) and they have the mass of about 1/400 and 1/200 (respectfully) the mass of a proton. But some quarks, like the Top quark (another uncreative name) has the mass of the entire Tunston atom.
Up quarks and down quarks are in protons and neutrons.
Up quarks and down quarks are in protons and neutrons.
Six quarks: Up and down ; Charm and Strange; Top and Bottom.
Two up and one down quarks combination is the Creation of a proton.
Six quarks: Up and down ; Charm and Strange; Top and Bottom.
Six quarks: Up and down ; Charm and Strange; Top and Bottom.
Both protons and neutrons consist of "up" and "down" quarks.
