Helicity (fluid mechanics) — this page is about helicity in fluid mechanics. For helicity of magnetic fields, see magnetic helicity. For helicity in particle physics, see helicity (particle physics). In fluid mechanics, helicity is the extent to which corkscrew like motion… … Wikipedia
Magnetic helicity — In plasma physics, magnetic helicity is the extent to which a magnetic field wraps around itself . It is a generalization of the topological concept of linking number to the differential quantities required to describe the magnetic field. As with … Wikipedia
Weinberg-Witten theorem — Steven Weinberg and Edward Witten consider the so called emergent theories to be misguided. During the 80 s, preon theories, technicolor and the like were very popular and some people were speculating that gravity might be an emergent phenomena… … Wikipedia

Neutrino — For other uses, see Neutrino (disambiguation). Neutrino/Antineutrino The first use of a hydrogen bubble chamber to detect neutrinos, on November 13, 1970. A neutrino hit a proton in a hydrogen atom. The collision occurred at the point where three … Wikipedia
Neutrino theory of light — The neutrino theory of light is the proposal that the photon is a composite particle formed of a neutrino antineutrino pair. It is based on the idea that emission and absorption of a photon corresponds to the creation and annihilation of a… … Wikipedia

Magnetohydrodynamic turbulence — Magnetohydrodynamics (MHD) deals with what is a quasi neutral fluid with very high conductivity. The fluid approximation implies that the we focus at macro length and time scales which are much larger than the collision length and collision time… … Wikipedia
Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For … Wikipedia
Optical vortex — An optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1]… … Wikipedia
