what do the columns and rows of the metric correspond to?
my linear algebra book says that a matrix is orthogonal iff its columns
form an orthonormal set of vectors I suppose the minkowski metric eta(alpha, beta) is orthogonal, as it seems that if the rows correspond to unit vectors in the t, x, y, z directions, the columns appear to be an orthonormal set am I assigning the right meanings to the rows and columns of the minkowski metric there? what would the rows and columns correspond to when alpha and beta are superscripted? when just one is? -- +---{==================- ! --%- --U- /\ /\ Fritz Reitz, UW box 357920, CHDD SB-202, 543-9023 /\ /\ ~~~~. ooooo \ ' / http://staff.washington.edu/freitz/page1/index.html -O=O- ~~~~. ooooo \ / -==================}---+ / ^ \ ~~~~. ||||| '
