    I thought it was meant to be the cat. Stupid entanglement.

    Don't bother thinking about string theory or other theories that aren't solidified until you are through everything else. Mechanics is a good place to start. It works with problems that you can imagine physically (bonus), yet the problems can be quite difficult. Do you have any mechanics textbook?

    Good post Schnitzel.

    I think ygolo has a decent grasp of the more simple stuff already. Though learning classical mechanics stuff can be pretty important. I bridged engineering to physics and it is quite important to know that stuff when making the next step to higher level quantum stuff. Otherwise the approach can look somewhat alien.

    Yeah, the Lagrangian and Hamiltonian approaches do seem a little weird, but the equations are easy enough to derive.

    I've also done some study of quantum mechanics on my own, and I am fairly comfortable with Hilbert Spaces.

    If you open a blog or post links to read here and/or comments, I'd surely read as much as I can (though, I'm still in school so I won't be able to read in detail). Good luck with that, being a physicist has always been my dream too, maybe I will too try to get a BS in it while working, after finishing with economics.

    We can use this thread...

    I've decided that basic electromagnetism is straight forward enough.

    So I am trying to understand the covariant formulation, while learning the formalism for special relativity.

    It seems like a good place to start...special relativity.

    Anyone know good sources?

    I read Einstein's popular exposition when I was a kid, but he didn't really use the formalism there. He just made the case that starting with the principle of relativity and that the speed of light in a vacuum is constant, that you get the Lorentz Transformations. There was also some exposition for E=m*c^2/(1-v^2/c^2)^0.5, and that cool Taylor expansion where E=m*c^2+(1/2)m*v^2+...

    I reviewed this stuff using wikipedia here.

    But it seems like to understand any of the "classical" stuff, we need to understand four-vectors, Minkowski space-time, and the use of Tensors to delay the action of feilds and forces to account for the maximum information transfer limit at the speed of light.

    Accept the past. Live for the present. Look forward to the future.

    Good luck. I find string theory and quantum physics absolutely fascinating. Although to understand it somewhat I have to resort to the QP for dummies documentaries.
