It turns out that the evolution operator for a quantum-mechanical wave function can be expressed as a sum over all paths with fixed endpoints in space-time weighted by a phase factor that depends only on the Lagrangian integrated along the path. ...

Mean field theory and Hartree
... Perhaps the first mean-field theory was the alteration of the Curie law χ ∝ 1 / T for a paramagnet, to the Curie-Weiss law χ ∝ 1 / (T − Tc ) for a ferromagnet at T above the Curie temperature Tc. The derivation says that roughly speaking, a microscopic spin sees, not the separate spins on its neighb ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
