Thanks, and ditto, btw.
Ahh...well, there's more to theoretical physics than umpteen-dimensional theories with strings and branes and whatknots. I personally am not into all that (at least not yet). But, like I said, I just started on my masters, and I don't think it's quite appropriate to start with such highly speculative conjecturing when there's still a lot that needs to be grasped about already established theories, theories with actual experimental support. Theories like relativity and quantum mechanics are deep and subtle theories with somewhat elusive aspects that I think ought to be explored before I even start considering the hypotheses of the many "rogue theorists" (aka string "theorists") and such. I'm not even ready to abandon a strictly 4-dimensional world-view!
