51Merkle signature scheme — The Merkle signature scheme is a digital signature scheme based on hash trees (also called Merkle trees) and one time signatures such as the Lamport signature scheme. It was developed by Ralph Merkle in the late 70s and is an alternative to… …
52Electron paramagnetic resonance — (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. The… …
53g-factor (physics) — For the acceleration related quantity in mechanics, see g force. A g factor (also called g value or dimensionless magnetic moment) is a dimensionless quantity which characterizes the magnetic moment and gyromagnetic ratio of a particle or nucleus …
54Spintronics — (a neologism meaning spin transport electronics [1][2]), also known as magnetoelectronics, is an emerging technology that exploits both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental… …

56Electron magnetic dipole moment — In atomic physics, the magnetic dipole moment of an electron is caused by its intrinsic property of spin within a magnetic field. Explanation of magnetic momentThe electron is a negatively charged particle with angular momentum. A rotating… …
57Nuclear drip line — In nuclear physics, the boundaries for nuclear particle stability are conceptualized as drip lines. The nuclear landscape is understood by plotting boxes, each of which represents a unique nuclear species, on a graph with the number of neutrons… …
58Outline of physics — See also: Index of physics articles Physics (Greek: physis – φύσις meaning nature ) is a natural science pertaining to the study of matter[1] and its motion through spacetime and all that derives from these, such as energy and force.[2] More… …
