Just to weigh in on this. This is mainly addressed to Michael.
"no clue" is more an attitude than a level of understanding. As long as you are always looking to know more, you can never have "no clue". The moment you think you have all the answers is the moment you have "no clue"... new graduates are by far the worst example of this!
This is closer to what most physicists mean when they say somebody has "no clue". Everyday, the more I read about any subject, I always end up slapping myself on the head and thinking:
"Man, and here I thought I understood the French Revolution/First Person Shooter Graphics engines/Virology/.......e.t.c."
In every subject I realize that my previous ideas of "what it was all about" were silly and uninformed. Just today, for instance, I was given a book by a friend about Late Jurassic Dinosaurs living in Antarctica. There's a whole ecosystem I know nothing about.
So don't worry. I know far less about dinosaurs than a palaeontologist. I'll also never be at the cutting edge of palaeontological research, but sure so what?
Those "don't have a clue" comments are directed mainly at people who don't want to understand because they already have it all "figured out". Eventually you get pissed off with them and say something that sounds like a harsh generalization.
So in essence, read what you want to read and you'll learn what you want to learn.
It might take a while before you get GR, but it'll be a while before I'm up to speed on Cryolophosaurus.
(I hope this didn't sound like an after school special)
