qcd mp21k QCD Made Simple Quantum chromodynamics is conceptually simple. Its realization in nature, however, is usually very complex. But not always. Frank Wilczek Quantum chromodynamics, familiarly called QCD, is the modern theory of the strong interaction.1 Historically its roots are in nuclear physics and the description of ordinary matter--understanding what protons and neutrons are and how they interact. Nowadays QCD is used to describe most of what goes on at high-energy accelerators. http://www.aip.org/pt/vol-53/iss-8/p22.html 040904 ... mp21k "Quantum Chromodynamics (QCD) is the" "physical" Physics (from Greek from öõóéêüò (physikos): natural, from öýóéò (physis): Nature) is the study of energy and its interaction with matter (see chemistry, biology). Because of the primacy of energy in terms of the history of the universe, because all matter must interact with energy to express its properties and engage in transformations, and because energy is the key player when matter is decomposed into its most basic parts, physics is often considered to be the fundamental science. .....

Every observed physical phenomenon, from galaxies colliding with each other to quarks jiggling around inside a proton, can thus be explained by these interactions. Because of their fundamental importance, their understanding has occupied the attention of physicists for over half a century, and continues to do so. ..... Click the link for more information. ", the strong interaction" The strong nuclear force or strong interaction is a fundamental force of nature which affects only quarks, antiquarks, and is mediated by gluons in a similar fashion to how the electromagnetic force is mediated by photons. This force is responsible for binding quarks together to form hadrons (including protons and neutrons), and the residual effects also bind these neutrons and protons together in the nucleus of the atom. .....

He received a Bachelor of Science in Mathematics at the University of Chicago in 1970, a Master of Arts in Mathematics at Princeton University, 1972, and a Ph.D. in Physics at Princeton University in 1974. Frank Wilczek is a Professor of Physics at MIT. He worked at the Institute for Advanced Study in Princeton and the Santa Barbara Research Institute. ..... Click the link for more information.

"It uses quantum field theory" Quantum field theory (QFT) is the application of quantum mechanics to fields. It provides a theoretical framework widely used in particle physics and condensed matter physics. In particular, the quantum theory of the electromagnetic field, known as quantum electrodynamics, is one of the most well-tested and successful theories in physics. The fundamentals of quantum field theory were developed between the late 1920s and the 1950s, notably by Dirac, Fock, Pauli, Tomonaga, Schwinger, Feynman, and Dyson. .....

"to describe the interaction of quarks" For other uses of this term, see: Quark (disambiguation) In particle physics, the quarks are subatomic particles thought to be elemental and indivisible. They are one of the two families of spin-1/2 fermions (the other being the leptons). Objects made up of quarks are known as hadrons; well known examples are protons and neutrons. Quarks are generally believed to never exist ..... Click the link for more information. "and gluons" In physics, gluons are the elementary particles which are responsible for the strong nuclear force. They bind quarks together to form protons and neutrons as well as other hadrons; their electric charge is zero, their spin is 1 and they are generally assumed to have zero mass (although a mass as large as a few MeV may not be precluded). Gluons are ultimately responsible for the stability of atomic nuclei; there are eight different kinds of gluons. .....
