Book Review

Back in 1964, Richard Feynman famously stated that “Nobody understands quantum mechanics.” Indeed, despite its impressive empirical success, quantum mechanics (QM) remains the most perplexing and mind-boggling theory ever produced by humans. In his clear and thought-provoking book, Jean Bricmont advocates the merits of “the de Broglie–Bohm theory” and forcefully argues that it provides an intelligible picture of the quantum world out there. Being aware, however, that the de Broglie–Bohm theory is not immune from difficulties, the author acknowledges that understanding QM is an “unfinished story” (292).

After a short introductory chapter, Bricmont discusses in Chapter 2 what he calls the “first mystery” of quantum mechanics, namely “interference and superpositions.” Spin measurements with Mach–Zehnder interferometers (§ 2.2) show that the quantum state is a superposition of two incompatible states (spin up and spin down). When a measurement is performed, the quantum state instantly...



The author is indebted to Jean Bricmont and Harvey Brown for their useful comments on a first draft of this review.
