1Parton (particle physics) — In particle physics, the parton model was proposed by Richard Feynman in 1969 as a way to analyze high energy hadron collisions. [R. P. Feynman, Proceedings of the 3rd Topical Conference on High Energy Collision of Hadrons, Stony Brook, N. Y.… …
2Jet (particle physics) — A jet is a narrow cone of hadrons and other particles produced by the hadronization of a quark or gluon in a particle physics or heavy ion experiment. Because of QCD confinement, particles carrying a color charge, such as quarks, cannot exist in… …
3Ionization cooling — Physical Principle = Ionization cooling is a process by which the beam emittance of a beam of particles may be reduced [G.I. Budker, in: Proceedings of 15th International Conference on High Energy Physics, Kiev, 1970A.N. Skrinsky, Intersecting… …
4Mass in special relativity — incorporates the general understandings from the concept of mass energy equivalence. Added to this concept is an additional complication resulting from the fact that mass is defined in two different ways in special relativity: one way defines… …
5Phonon — For KDE Software Compilation 4 s multimedia framework, see Phonon (KDE). Normal modes of vibration progression through a crystal. The amplitude of the motion has been exaggerated for ease of viewing; in an actual crystal, it is typically much… …

7Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… …
8solids, mechanics of — ▪ physics Introduction science concerned with the stressing (stress), deformation (deformation and flow), and failure of solid materials and structures. What, then, is a solid? Any material, fluid or solid, can support normal forces.… …
9Nuclear magnetic resonance — This article is about the physical phenomenon. For its use as a method in spectroscopy, see Nuclear magnetic resonance spectroscopy. NMR redirects here. For other uses, see NMR (disambiguation). First 1 GHz NMR Spectrometer (1000 MHz,… …
10Comparison of American football and rugby union — A comparison of American football and rugby union is possible because of the games shared origins, despite their dissimilarities. A rugby union match from the 2011 Rugby World Cup showing the sports distinguishing feature, the ball carrier leads… …
