I would advise Dave to have a look at the Enigmatic Photon books on the Omnia Opera of _www.aias.us_ (http://www.aias.us) . These deal with angular momentum theory in 3 and 4 dimensions in special relativity, using the Lorentz and Poincare group generators, the Pauli Lubanski formalism and so on. This is advanced field theory, by no means easy. I wrote these books with advice from Vigier in the manner of Landau and Lifshitz, Lifsgitz wrote teh books with advice from Landau. Essentially, on the simplest level, angular momentum has to do with rotation, so torsion has to do with rotation. Have a look at the downloadable notes by Carroll, where in his chapter one he gives the rotational Lorentz transform, much less well known than the Lorentz boost. Ryder leaves out all the c’s and h bar’s and is often obscure. However he is quite good if one can spend many hours (or in my case years) trying to sort out what he is saying. Very few people have the time or inclination to go deeply into advanced field theory, which in the standard model is a plethora of hyper-complexity.
