Quantum Paradoxes: Quantum Theory for the PerplexedISBN: 9783527403912
299 pages
April 2005

Yakir Aharonov is one of the pioneers in measuring theory, the nature of quantum correlations, superselection rules, and geometric phases and has been awarded numerous scientific honors. The author has contributed monumental concepts to theoretical physics, especially the AharonovBohm effect and the AharonovCasher effect.
Together with Daniel Rohrlich, Israel, he has written a pioneering work on the remaining mysteries of quantum mechanics. From the perspective of a preeminent researcher in the fundamental aspects of quantum mechanics, the text combines mathematical rigor with penetrating and concise language. More than 200 exercises introduce readers to the concepts and implications of quantum mechanics that have arisen from the experimental results of the recent two decades.
With students as well as researchers in mind, the authors give an insight into that part of the field, which led Feynman to declare that "nobody understands quantum mechanics".

Dr. Daniel Rohrlich, born in 1954, received his Ph.D. in physics from the State University of New York at Stony Brook in 1986. He currently works as a research scientist at the Weizmann Institute in Rehovot, Israel. His research interests lie in the fields of quantum information, fundamental aspects of quantum mechanics, path integrals, and experimental mesoscopic physics.
