“The untold story of the heretical thinkers who dared to question the nature of our quantum universe
Every physicist agrees quantum mechanics is among humanity’s finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr’s Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr’s students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.”
While What is Real? The Unfinished Quest for the Meaning of Quantum Physics is marketed as a popular science book, it should be mandatory reading for professional physicists, as it is a critical history of their field first and foremost, trying to explain why a problematic theory like the Copenhagen interpretation of quantum mechanics has endured for so long.
It works both as a solid overview of the science and possible interpretations of quantum theory, and as a sociological history of the workings of the field – both from a European and American perspective. There is much to learn here: about quantum science, about science as a practice, and about philosophy of science as well. Continue reading
