Where Can I Learn String Theory Online with Math and Everything?

[Superposed_Cat]

Where can I learn string theory online with the math and everything? ANY help appreciated. Tanks in advance.

Ps I'm looking for links, I really can't afford books. I'm a high school student. I know the principles but haven't attempted any math above the Schrödinger equation for a quantum well. If I need extra math where can I learn that?

Thanks and whoa, 7,192 posts aty y! How long has this forum been up?

Actually, I don't know. I found this a few years ago, and had the impression it had already been up for some years then. Maybe ZapperZ or D H or Borek would know?

Do you really think you're ready for string theory?

I think you should make sure you know how to walk before you try to skip. You might end up standing on your face.

I think he needs to learn how to breathe first.

OP, after reading your previous posts, I'd say this link is invaluable for you. You should follow the links through from the top.

I preffered the second one so far

The fourth link is also nice but why is energy a vector?

You mean in equation 1.1? That E vector is the electric field and the integral is calculating the energy contained in that field.

Thanks, I am such a n00b :-)

IDK about string theory online, but Britney Spears has a nice site which explains semiconductor physics, if you are interested:

Thanks steam king and jtbell, I thought you were joking when you said the Britney thing.
