The Intensity 7 ( 震度7, Shindo 7) is the maximum intensity in the Japan Meteorological Agency seismic intensity scale, covering earthquakes with an instrumental intensity (計測震度) of 6.5 and up. [ 15] At Intensity 7, it becomes impossible to move at will. [ 13] The intensity was created following the 1948 Fukui earthquake.
Spin — an aggravated stall and autorotation. In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. [ 1] Spins can be entered intentionally or unintentionally, from any flight ...
Spintronics. Spintronics (a portmanteau meaning spin transport electronics[ 1][ 2][ 3] ), also known as spin electronics, is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. [ 4] The field of spintronics concerns spin-charge coupling in ...
Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [ 1][ 2]: 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
In condensed matter physics, a spin glass is a magnetic state characterized by randomness, besides cooperative behavior in freezing of spins at a temperature called "freezing temperature" Tf. [ 1] In ferromagnetic solids, component atoms' magnetic spins all align in the same direction. Spin glass when contrasted with a ferromagnet is defined as ...
Spin isomers of hydrogen. Spin isomers of molecular hydrogen. Molecular hydrogen occurs in two isomeric forms, one with its two proton nuclear spins aligned parallel (orthohydrogen), the other with its two proton spins aligned antiparallel (parahydrogen). [ 1] These two forms are often referred to as spin isomers [ 2] or as nuclear spin isomers.
Physics of spin-flips. A spin-flip is a late stage in the evolution of a binary black hole. The binary consists of two black holes, with masses and , that revolve around their common center of mass. The total angular momentum of the binary system is the sum of the angular momentum of the orbit, , plus the spin angular momenta of the two holes.
A spin- 1 2 particle is characterized by an angular momentum quantum number for spin s of 1 2 . In solutions of the Schrödinger equation, angular momentum is quantized according to this number, so that total spin angular momentum. However, the observed fine structure when the electron is observed along one axis, such as the z ...
