## The Physical Principles of the Quantum TheoryThe contributions of few contemporary scientists have been as far reaching in their effects as those of Nobel Laureate Werner Heisenberg. His matrix theory is one of the bases of modern quantum mechanics, while his "uncertainty principle" has altered our whole philosophy of science. |

User Review - mobill76 - LibraryThingI have long been perplexed by the paradoxes inherent in modern physics. But, the lecturers that I've heard seem to state these paradoxes glibly. They even seem to revel in them as a "pons asinorem ... Read full review

This excellent book is a cheap way, (< $10 at review time), to get a view of how Heisenberg thought about quantum mechanics circa 1930. The book is constructed from his notes for a series of lectures given at the University of Chicago. The book is about 3/4 text discussing an overview of quantum theories and the experiments that led up to/verified those theories. The last quarter or so is dedicated to laying out the mathematical formalism.
