The first comprehensive philosophical and historical account of the experimental foundations of Niels Bohr’s practice of physics.

Niels Bohr was a central figure in quantum physics, well known for his work on atomic structure and his contributions to the Copenhagen interpretation of quantum mechanics. In this book, philosopher of science Slobodan Perović explores the way Bohr practiced and understood physics, and analyzes its implications for our understanding of modern science. Perović develops a novel approach to Bohr’s understanding of physics and his method of inquiry, presenting an exploratory symbiosis of historical and philosophical analysis that uncovers the key aspects of Bohr’s philosophical vision of physics within a given historical context.

To better understand the methods that produced Bohr’s breakthrough results in quantum phenomena, Perović clarifies the nature of Bohr’s engagement with the experimental side of physics and lays out the basic distinctions and concepts that characterize his approach. Rich and insightful, Perović’s take on the early history of quantum mechanics and its methodological ramifications sheds vital new light on one of the key figures of modern physics.

Review Quotes
Helge Kragh, Niels Bohr Institute, University of Copenhagen
"Perović offers a novel and refreshingly unorthodox interpretation of Bohr's seminal contributions to quantum physics and their philosophical implications. Adopting a method of historically sensitive analysis, he argues convincingly that the great Dane came to his overarching hypotheses, including the complementarity principle, by inductive reasoning inherently based on experiments. He skillfully defends Bohr against the charges that his epistemological and methodological views were amateurish armchair philosophy. Perović's book on Bohr's vision is recommendable from a scientific, historical, and philosophical perspective."
Kristian Camilleri, University of Melbourne
"In this book, Perović provides a fascinating new perspective on Bohr's unique approach to physics, in which experiment played a pivotal role in the very process of constructing new theories. Here Perović weaves together careful historical research with philosophical insight in presenting an image of Bohr as a theoretical physicist whose thinking was deeply immersed in the daily workings of the laboratory. This book constitutes a valuable contribution to Bohr scholarship and the philosophy of scientific practice."
Hasok Chang, University of Cambridge
"Perović has given us a most welcome reassessment of Bohr’s methodology of science. He makes an insightful analysis of Bohr's many-layered approach, which started with considerations of specific experiments and gradually and carefully went into deeper theoretical and philosophical ideas. This detailed and imaginative study successfully rehabilitates Bohr and defends his views from many unsympathetic critics, then and now. Perović's book is a major addition to the literature in the history and philosophy of modern physics, and also an exemplary study integrating the history and the philosophy of science."
