    I am planning on learning General Relativity, and I was just wondering how I should go about doing this. Research seems to indicate that learning Differential Geometry should be the first thing to do. Here is where I need help: how should I tackle Differential Geometry? There seem to be three different approaches: curves and surfaces embedded in three dimensional euclidean space, sub/super-script heavy tensor analysis, and coordinate-free tensor analysis. Is it wise to go through all of these first, or should I just take on a selection of them? Is there any particular order I should take them on in?


    I demand that my name may or may not be vroomfondel!

    Learn history of spacetime in chronological order to which it was first devised. By early spacetime I mean before Einstein like Rienmann and Eucledian as you said. Know all you can about mathematics of geometry and then move onto relativity.

    Unlike me I jumped in the deep end and started on Special Relativity.

    I am already very familiar with Special Relativity. I have taken a few attempts at learning GR, (from Shutz's "A First Course in General Relativity) and I could do the math, but I didn't really understand exactly what it was that I was doing with the tensors. This gave me the idea to do Differential Geometry.

    You've got me there, I just stick with the basics, I'm still working on going furthur . Not sure anyone on this forum knows a great deal about GR. Maybe Janus might, and seeing as I've said his/her name (most likely a he) he'll rear his head here :wink:.

    I'm sure we'll all read your future posts in a new light then :wink:
