Learning theoretical physics is hard, but the fact is it doesn't have to be impossible. If you build a solid foundation I believe just about anyone who is willing to put the work in can gain a general understanding of physics. Its my goal to help make that happen for thousands of people with my Demystified series books.
The first book in the series that came out teaches what most universities would consider first semester quantum mechanics, either at the undergraduate or graduate level. The difference with my book is that I've tried to write it with the student in mind. So instead of long, detailed, wordy explanations that leave your head spinning I cut to the chase and just say what needs to be said. More importantly each chapter is packed with solved examples that don't leave out any details. You can find it on Amazon at:
To master quantum mechanics you also have to learn linear algebra. Linear algebra demystified is available at:
All of the books follow the same format.
