54Electrodynamic tether — Electrodynamic tethers are long conducting wires, such as the one deployed from the tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting …
55Centimetre–gram–second system of units — CGS redirects here. For other uses, see CGS (disambiguation). The centimetre–gram–second system (abbreviated CGS or cgs) is a metric system of physical units based on centimetre as the unit of length, gram as a unit of mass, and second as a unit… …
56T-symmetry — is the symmetry of physical laws under a time reversal transformation mdash;: T: t mapsto t.Although in restricted contexts one may find this symmetry, the universe itself does not show symmetry under time reversal. This is due to the uncertainty …
57Electro-gyration — The electrogyration effect is the spatial dispersion phenomenon, that consists in the change of optical activity (gyration) of crystals by a constant or time varying electric field. Being a spatial dispersion effect, the induced optical activity… …
