This is one of several shortened indices into the Quantum Physics Sequence. It is intended for students who are having trouble grasping the meaning of quantum math; or for people who want to learn the simple math of everything and are getting around to quantum mechanics.

There's a widespread belief that quantum mechanics is supposed to be confusing. This is not a good frame of mind for either a teacher or a student. Complicated math can be difficult but it is never, ever allowed to be confusing.

And I find that legendarily "confusing" subjects often are not really all that complicated as math, particularly if you just want a very basic - but still mathematical - grasp on what goes on down there.

This series takes you as far into quantum mechanics as you can go with only algebra. Any further and you should get a real physics textbook - once you know what all the math means.
