As many of you know, I am in the process of making a career-change from Engineer to Physicist. Right now, it seems like I want to get into High Energy Physics--Theory as the ultimate goal...This means working on things like String Theory and Quantum Gravity or working out their implications for achievable experiments (eventually). I think I would prefer working on phenomenology over creating new theories at this point...but that may change.
However, it is a long trek from where I am to where I would like to be. I will be enrolling at a near-by state college in Undergraduate Physics in the fall, but I know that most of my learning will be on my own (as it usually is).
Even though the eventual aim is to learn High-Energy Theory, there are a LOT of pre-requisites. I made an initial list of what I believe I need to learn here.
I've started the process here.
I will be utilizing some help from physicsforums, as well...but relatively speaking, I'm a n00b. So it would be fun to have other n00b's (even if just one) learning along with me.
Also, I learned of a handy resource for current data on particle physics:
