I don't care how smart you are, you are going to reach a point where it doesn't make any sense even though it is supposed to establish the fundamental laws of the universe. Once you have mastered Newtonian physics, you will think you are pretty smart and you will then step into quantum mechanics. At that point in your studies, you will want to remain close to a high window because there will be times when you see no other solution to your problems other than to throw yourself out of it.

But, Chas is right, the best place to start is Khan Academy.

I'm currently reading Quantum Theory: A Very Short Introduction (Very Short Introductions)

They are an excellent series of books but I'm not so sure about this one. But it is what it says, a very short introduction.

I really enjoyed Nothing: A Very Short Introduction and I will reading one by the same author on particle physics next.

But this article in New Scientist today made me feel a lot better about the subject of quantum mechanics.

About your maths Big Grin, why not ask at your local college if there are maths/physics students who are interested in doing some tutoring. it would help a lot. Some students just don't get maths until, say, their mid-20s or later, and then wonder what the problem was.

Edited to add: just kidding about the "math"/"maths" difference.

I just bought aBasic Physics book off of Amazon. I've watched the MIT open course videos on Youtube but was lost within 5 minutes. Basically as soon as the Prof was done introducing himself. I'm just wondering if anyone has any other suggestions?

Some great suggestions already.
Also, you can always ask here or write e.g. me a pm. There are some dedicated physics forums out there, maybe there's onrle you feel comfortable in...

RE: Physics for newbs
Hi - Another really fun series of Berkeley lectures is "Physics 10 - Physics for Future Presidents" with playlist link below. The series started when Bush Jr was president, so the title makes a bit more sense. This series covers basics of matter and energy with fun relevant topics: solar versus other fuels, atom bombs, how did the twin towers fall, etc. I have a B.S. in physics and still listen and re-listen to this, and always learn something.

Do you want a qualitative conceptual understanding?
Or do you want to solve path integrals?

... or just have enough knowledge to be able to understand cjlr's questions?
