Ebook: Quantum mechanics demystified

"Now anyone can master the basics of quantum mechanics-without formal training, unlimited time, or a genius IQ. In Quantum Mechanics Demystified, physicist (and student-savvy author) David McMahon provides an effective and illuminating way to learn the essentials of quantum mechanics." "With Quantum Mechanics Demystified, you master the subject one step at a time-at your own speed. This unique self-teaching guide is filled with solved examples throughout, and offers problems to try at the end of each chapter to pinpoint weaknesses. A final exam serves to reinforce concepts covered in the entire book. Book jacket."--BOOK JACKET. Read more... 1.
