81History of gravitational theory — In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times.AntiquityIn the 4th century BC, the Greek philosopher… …
82ΔT — This article is about the time difference. For the temperature difference, see psychrometrics. ΔT vs. time from 1657 to 1984[1] ΔT, Delta T, delta T, deltaT, or DT is the time difference obtained by subtracting Universal Time (UT) from… …
83Lorentz transformation — A visualisation of the Lorentz transformation (full animation). Only one space coordinate is considered. The thin solid lines crossing at right angles depict the time and distance coordinates of an observer at rest with respect to that frame; the …
84Spintronics — (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… …

86Earth's orbit — In astronomy, The Earth s Orbit involves the Earth orbiting the Sun at an average distance of about 150 million kilometers every 365.2564 mean solar days (1 sidereal year). From Earth, this gives an apparent movement of the Sun with respect to… …
87Euler's equations (rigid body dynamics) — This page discusses rigid body dynamics. For other uses, see Euler function (disambiguation). In physics, Euler s equations describe the rotation of a rigid body in a frame of reference fixed in the rotating body:egin{matrix}I 1dot{omega} {1}+(I …
88Timekeeping on Mars — Various schemes have been used or proposed to keep track of time and date on the planet Mars independently of Earth time and calendars. Mars has an axial tilt and a rotation period similar to those of Earth. Thus it experiences seasons of spring …
89Scalar theories of gravitation — are field theories of gravitation in which the gravitational field is described using a scalar field, which is required to satisfy some field equation. Note: This article focuses on relativistic classical field theories of gravitation. The best… …
