Mach number (E. Mach): It is the ratio of the speed of an object in a specified medium to the speed of sound in that medium.
Tau-theta paradox (1950s): Whenever two distinct kinds of kaons, tau and theta (nowadays tau refers to a totally different particle) decay, tau decays into three particles, whereas the theta decays into two. The tau and theta vary onl
Volt: V (after A. Volta, 1745-1827): The derived SI unit of electric potential, stated as the difference of potential among the two points on a conductor fetching a constant current of 1 A whenever the power dissipated between the points is 1 W;
