21Special relativity — (SR) (also known as the special theory of relativity or STR) is the physical theory of measurement in inertial frames of reference proposed in 1905 by Albert Einstein (after considerable contributions of Hendrik Lorentz and Henri Poincaré) in the …
22Warp drive (Star Trek) — Warp drive redirects here. For the actual model of spacetime, see Alcubierre drive. A visualization of a warp field. The ship rests in a bubble of normal space. Warp drive is a faster than light (FTL) propulsion system in the setting of many… …
23Collision response — In the context of classical mechanics simulations and physics engines employed within video games, collision response deals with models and algorithms for simulating the changes in the motion of two solid bodies following collision and other… …

25radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …
26Lamb waves — propagate in solid plates. They are elastic waves whose particle motion lies in the plane defined by the plate normal and the direction of wave propagation. In 1917, the English mathematician Horace Lamb published his classic analysis and… …
27Stellar kinematics — is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful… …
28Oort constants — The Oort constants (discovered by Jan Oort) A and B are empirically derived parameters that characterize the local rotational properties of our galaxy, the Milky Way, in the following manner: where V0 and R0 are the rotational velocity and… …
