Yes pervect, I get your point, but still is quite annoying for me to think something came out from nowhere. I suppose the transformation law given (http://rmp.aps.org/pdf/RMP/v21/i3/p447_1 see beginning of page 3) should have some meaning and I would like to have an idea how to get it. If you...

Ok, I should have explained myself better. The original metric is written in cartesian coordinates x_0, x_1, x_2 and x_3 (metric signature (+,-,-,-)). He wants to show his metric has rotational symmetry so he goes to cylindrical coordinates. However, as we have local rotation around the x_3...

Hello, In Godel's paper: an example of a new type of cosmological solutions of einstein's field equations of gravitation, he passes from his original metric to cylindrical coordinates by giving some transformation formulas. Can someone tell me how is this transformation obtained, or at least...
