Ampere the watt, the ohm and the volt. Rather than a definition in terms of the force between two current-carrying wires, it has been proposed that the ampere should be defined in terms of the rate of flow of elementary charges. Since a coulomb is approximately equal to elementary charges (such as those carried by protons, or the negative of those carried by electrons), one ampere is approximately equivalent to elementary charges moving past a boundary in one second. ( is the reciprocal of the value of the elementary charge in coulombs.) The proposed change would define 1 A as being
The Civil Wars: A Tree Is Best Measured When It Is Down The Civil Wars: A Tree Is Best Measured When It Is Down the CIVIL warS: a tree is best measured when it is down is an opera created in the early 1980s by director Robert Wilson to music by Philip Glass, David Byrne, Gavin Bryars and others. The vast five-act work has never been performed whole. Originally, "The Civil Wars" was conceived as a single daylong piece of music theatre to accompany the 1984 Summer Olympics. Six different composers from six different countries were to compose sections of Wilson's text inspired by the American Civil War. After initial premieres in
