metrik-e Minkofski (#)
Fr.: métrique de Minkowski
The → metric that belongs to a four-dimensional → flat manifold and is given by ds2 = - dt2 + dx2 + dy2 + dz2. Three coordinates represent → space and the fourth coordinate is devoted to → time. The Minkowski metric underlies the → geometry of → special relativity. Compare → Robertson-Walker metric.
In honor of Hermann Minkowski (1864-1909), Russian-born German mathematician, who introduced the concept of the four-dimensional nature of space-time; → metric.
