Quantum Theory at the Crossroads

'Considering the development of quantum mechanics, Quantum Theory at the Crossroads offers a very stimulating viewpoint as its authors take a rather polarizing stance. Overall, it provides an important and inspiring history of quantum mechanics, being most valuable for its translation of the conference proceedings and its account of de Broglie's often neglected pilot-wave theory.' Martin Jähnert, Metascience
'… a most useful volume for historians and philosophers of physics alike. The excellent introduction and the important sources make [it] a most valuable contribution to the philosophy and history of quantum mechanics. It should be included in the reading list of every class on that subject, and it should be read by anyone who is concerned with the conceptual problems of quantum mechanics. I also recommend it to physicists who are looking for a good place to start reading about the historical emergence of interpretational problems of modern quantum theory.' Isis
'… this book could play a role in guiding readers to the original works of de Broglie and Bohm, and … promote a more open-minded appreciation of their contributions than is customary even now.' Contemporary Physics
'… the book is already a very important contribution to our understanding of the Fifth Solvay Conference. The translation of the proceedings will make the various voices of the various participants much more accessible to a wide audience, and the historical account of how the conference came to be, how the various participants thought about and prepared their own contributions, and how the proceedings themselves were prepared will be an eye-opener for many readers. The truth about the conference is far more interesting than the fictions that are usually promulgated, and the authors do an excellent job debunking those fictions. Perhaps the lesson to learn here is that contemplating the Fifth Solvay Conference is a bit like taking a Rorschach inkblot test. The authors' own contemplation is ambitious, thought provoking, delightfully detailed, and itself deserving of further contemplation.' Michael Dickson, Philosophy of Science
'On the whole, the authors' arguments are well thought through and balanced. But in my opinion the most vital aspect of the book is that it highlights de Broglie's historical position and tries to understand why his achievements were neglected, and for this reason alone I would recommend this book.'
