A group of fundamental, spin / particle that have color charge and fractional electric charge. It makes up such particles as neutrons, protons, and pions, all of which are hadrons. In German "quark" means liquid cheese. See also: spin, hadron, Debriefing
One of the fundamental constituents of matter. These particles posses spin 1/2. They come in six flavors: up (u), down (d), strange (s), charm (c), bottom (b), and top (t). Only the up and down quarks are commonly found outside of accelerators. Protons and neutrons are composed of up and down quarks.
One of the subatomic particles from which many modern theoreticians believe such elementary particles as protons and neutrons are composed. The various kinds of quarks have positive or negative charges of 1/3 or 2/3.
Quarks are fundamental particles from which hadrons are formed. There are six types of quarks; up, down, charm, strange, top and bottom. Each has a spin of ½ and a charge of -1/3 or +2/3. Quarks are bound together through the exchange of gluons. Each quark has a corresponding antiquark as its antimatter particle.
A sub-atomic particle, thought to be the simplest of all particles. The quark theory was devised by the physicist Gell-Mann to explain the complex interactions of sub-atomic particles. They were named after a line from James Joyces's novel "Finnegan's Wake", "three quarks for Muster Mark".
An Elementary Particle which makes up the Neutron and the Proton, as well as many more exotic particles. These particles are Fermions, and have charges of either 2/3 as much as an electron's charge, or -1/3. They come in "flavors" of up, down, strange, charmed, bottom, and top, as well is in "colors" of red green and blue. The "flavor" and "color" are just fanciful names given to describe intrinsic properties of these particlesâ€”similar to charge, mass, or spin.
The basic building block of matter, and the foundation for modern theories of matter and the universe. Quarks combine with gluons to make the protons and neutrons that make up every atom in the universe. There are six varieties of quark: up and down, which make up most everyday matter, and the more exotic top, bottom, strange and charm quarks.
An elementary, strongly interacting constituent of matter. Quarks come in six flavors: up, down, charm, strange, top and bottom. The up, charm and top quarks have electric charges of +(2/3)e, while the down, strange and bottom quarks have charges of -(1/3)e. The proton which has a charge of +e is constructed of two up quarks and one down quark: (uud), while the neutron is (udd).
Any of a group of subatomic particles believed to be among the fundamental constituents of matter. In much the same way that protons and neutrons make up atomic nuclei, these particles themselves are thought to consist of quarks.
Quarks are subatomic particles that may be the fundamental constituents of baryons (like protons and neutrons) and mesons (like pions and kaons). Quarks have mass, charge (plus or minus 1/3 or 2/3), and spin. There are six types of quarks: up, down, strange, charm, top, and bottom. Baryons are made of 3 quarks each (protons and neutrons are made of up and down quarks); mesons are made of 2 quarks (a quark and an anti-quark). Murray Gell-Mann proposed the existence of quarks in 1964.
An elementary particle which is believed to be the fundamental structural unit from which all other particles are made. There are six quarks: up, down, strange, charm, top and bottom. A proton is made up of one down quark and two up quarks.
In particle physics, quarks are one of the two basic constituents of matter (the other are the leptons). Quarks are the only fundamental particles that interact through all four of the fundamental forces. The word was borrowed by Murray Gell-Mann from the book Finnegans Wake by James Joyce, where seabirds give "three quarks", akin to three cheers (probably onomatopoetically imitating a seabird call, like "quack" for ducks).
Quark, son of Keldar and Ishka, is a fictional character in the television series Star Trek: Deep Space Nine, played by Armin Shimerman, and a regular for the show's seven-year run. A member of the ultra-capitalist Ferengi, Quark owned a bar on the of Deep Space Nine.
Quark was an anthology book series devoted to avant-garde science fiction and related material, edited by fiction-writer and critic Samuel Delany and poet and editor Marilyn Hacker; four volumes were published in 1970 and 1971. The editors, once married, were among the foremost homosexual activist/writers in the following decades.
Quark was an American science fiction situation comedy starring Richard Benjamin that aired on NBC. The pilot first aired on May 7, 1977, and the series followed as a mid-season replacement in February 1978. The series was canceled in April 1978.
