The Strange World of Quantum Mechanics

This is an exceptionally accessible, accurate, and nontechnical introduction to quantum mechanics. After briefly summarizing the differences between classical and quantum behavior, this engaging account considers the Stern-Gerlach experiment and its implications, treats the concepts of probability, and then discusses the Einstein-Podolsky-Rosen paradox and Bell's theorem. Coverage introduces the quantal interference and the concept of amplitudes, and also reveals the link between probabilities and the interference of amplitudes. Final chapters explore exciting new developments in quantum computation and cryptography, discover the unexpected behavior of a quantal bouncing-ball, and tackle the challenge of describing a particle with no position. Thought-provoking problems and suggestions for further reading are included. Suitable for use as a course text, The Strange World of Quantum Mechanics enables students to develop a genuine understanding of the domain of the very small. It will also appeal to general readers seeking intellectual adventure.

Quantum mechanics appears strange and unfamiliar. However, for those who open their minds to the way in which nature really behaves - instead of clinging to preconceptions of how nature 'ought' to behave - the rules governing the domain of the very small are consistent, logical, and even delightful. This exceptionally accessible, accurate and non-technical account contains thought-provoking problems and suggestions for further reading. Suitable for use as a course text, it enables students to develop a genuine understanding of this subject. It will also appeal to general readers seeking intellectual adventure.

An exceptionally accessible, accurate and non-technical introduction to the core concepts of quantum mechanics.
