106Introduction to general relativity — General relativity (GR) is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by… …
107Atomic clock — Nuclear clock redirects here. For the clock as a measure for risk of catastrophic destruction, see Doomsday Clock. For a clock updated by radio signals (commonly but inaccurately called an atomic clock ), see Radio clock. For the album by Zion I …
108Tachyon — A tachyon (from the Greek polytonic|ταχυόνιον, takhyónion , from polytonic|ταχύς, takhýs , i.e. swift, fast) is any hypothetical particle that travels at faster than light speed. The first description of tachyons is attributed to German physicist …
109Magnetic circular dichroism — (MCD) is the differential absorption of left and right circularly polarized (LCP and RCP) light, induced in a sample by a strong magnetic field oriented parallel to the direction of light propagation. MCD measurements can detect transitions which …
110NOνA — Schematic of the NOνA far detector NOνA (NuMI Off Axis νe Appearance) is a particle physics experiment designed to detect neutrinos in Fermilab s NuMI (Neutrinos at the Main Injector) beam. Intended to be the successor to MINOS, NOνA will consist …
