Quantum mechanics? Well they were teaching us these things at high schooll and i can show you a 3rd grade book if you don''t believe me (it must be somewhere in a bookshelf...it''s been 6years till I last saw it, LOL)! Honestly there''s nothing hard if you spend some time reading it all. If you trust me rely on the final equations. All the other stuff is simply the mathematical documentation of the final equations on each page.
