Query: Useless book alert!

Pick another book like Serway's, or Tipler's, or even Modern Atomic and Nuclear Physics, for a legitimate introduction to this subject. Beiser's lazy treatment of Heisenberg's uncertainty principle and the Bohr atom amounts to little more than throwing out a few formulas and examples. The same goes for the transformations in special relativity - Tipler's treatment is superior. Even the Schaum's book in modern physics is better on this topic. His treatment of quantum mechanics was obviously meant to be ignored - hence the leaving out of important conceptual and explanatory material that, say, Modern Atomic and Nuclear Physics puts in. Overall, it is worthless in comparison to the previously mentioned books.
