An excellent work which innovatively combines conceptual clarity with penetrating analysis of relevant theory.
Helge Kragh, Annals of Science
Engineers and scientists from across the board will get a kick out of being able to read about the origins of their everyday toolkits - this is lucid historical reasoning about one of the great accomplishments of modern science. After seeing the author's track the launch of the old quantum theory, I'm looking forward to their account of full-blown quantum mechanics to come in volume 2!
Peter Galison, Harvard University
Clearly written, by highly competent authors, giving full reasoning and calculations for all important developments.
Olivier Darrigol, CNRS, France
This will be a widely read book and used in many physics and history of physics courses at the undergraduate college-university level. It will be greeted most enthusiastically by scholars and teachers alike.
Roger H. Stuewer, University of Minnesota
Indeed a very important and valuable contribution to the history of quantum mechanics.
Michael Eckert, Deutsches Museum, Muenchen
What seemed a good piece of work at the start is magisterial. This is the book I have been waiting to see for a long time.
Steven N. Shore, University of Pisa
This book will very likely become a new point of reference for everyone working on the history of quantum physics.
Christian Joas, Niels Bohr Archive
