Quantum Physics for Dummies by Steven Holzner is a comical juxtaposition of paragraphs of simple, facile exposition with abtrusely intricate mathematical formulae that I did not attempt to follow.
There are several grammatical, logical, and typesetting errors leading me to believe that the book was not thoroughly reviewed or edited. Some equations are repeated a multitude of times throughout the text, the Schrodinger equation alone no fewer than 12 times.
The book's main virtue in my reading of it was the great many concrete examples of matrices, state vectors, and hamiltonians giving a great flavor of how measured quantites at the initialization of an experiment are encoded into mathematical quantum states, and how the theoretically-modeled evolution of the state of the experiment is encoded as a series of operators. Besides, I learned some interesting high-level facts that will aid me in my upcoming physics education, such as that perturbation theory can in some cases yield an exact result after only finitely many refinements of the original hamiltonian.
All together, the book gave me what I purchased it for: concrete instances of the abstract concepts of state vector and operator, and some logical invariants to carry with me. But it was a little too long: the mathematical equations given are overly repetitious, and hard to follow because the bits under operation from one equality to another represent only a small portion of the overall equation as printed, and are even hard to find on occasion!
