"A thorough, illuminating exploration of the most consequential controversy raging in modern science." --New York Times Book Review
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 solipsistic and poorly reasoned Copenhagen interpretation. Indeed, questioning it has long meant professional ruin, yet some daring physicists, such as 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 the courageous scientists who dared to stand up for truth.
"An excellent, accessible account." --Wall Street Journal
"Splendid. . . . Deeply detailed research, accompanied by charming anecdotes about the scientists." --Washington Post
"In What Is Real?
Adam Becker tells a fascinating if complex story of
quantum dissidents...An excellent, accessible account."—Wall Street Journal
"A thorough, illuminating exploration of the most consequential controversy raging in modern science...[Becker] leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories, which are naturally messy and full of contingencies. He makes a convincing case that it's wrong to imagine the Copenhagen interpretation as a single official or even coherent statement."—New York Times Book Review
"Becker's book is one of the first attempts we have at
telling this story in a way that acknowledges how it actually turned
out--acknowledges, that is, who won these debates about the Copenhagen
interpretation, who lost them, who pretended otherwise, and how they got away
with it.... He has clearly done extensive and meticulous historical research."—David Z. Albert
, New York Review of Books
"Splendid.... With deeply detailed research,
accompanied by charming anecdotes about the scientists...[Becker] hopes to
convince us that the Cophenhagen interpretation has had too great an influence
on physics for historically contingent reasons."—Washington Post
"Becker...make[s] a case for the importance of philosophy. That's a key call, with influential scientists such as Neil deGrasse Tyson dismissing the discipline as a waste of time. What Is Real?
is an argument for keeping an open mind."—Nature
"A riveting storyteller, Becker brings to life
physicists who have too long remained in the shadow of Bohr and Einstein.... What Is Real?
offers an engaging and
accessible overview of the debates surrounding the interpretation of quantum
"Impressive...[Becker's] strength is the excavation of stories that show how deeply quantum physics was in thrall to the personalities of its developers. The cast is colourful and expansive, and provides engaging drama...The subtext running through this hugely enjoyable book is that, if we still have a long way to go before we understand reality, we may only have our own prejudices to blame."
"A joy to read...For anyone who has been intrigued by other popular accounts of the quantum world but came away feeling somewhat cheated by the Copenhagen sleight-of-hand."—Physics World
"Remarkable...What Is Real?
is a superb contribution both to popular understanding of quantum theory and to ongoing debates among experts...It deserves wide attention and careful study."—Physics Today
"Spellbinding....This very book could prove to be a watershed moment for the physics community if it faces up to its own past and its present....If you have any interest in the implications of quantum theory, or in the suppression of scientific curiosity, What is Real? is required reading. There is no more reliable, careful, and readable account of the whole history of quantum theory in all its scandalous detail."
"Becker has done a great service in putting this fascinating story together into a single easily-digestible volume that is gripping, authoritative, and true....I sincerely hope it gains an extremely wide readership and manages to have a powerful influence."—Quantum Times
"A page turner...Becker writes very well...To any one with more than a passing interest in QM, how it came to be the way it is, and how it might be otherwise, this book will be irresistible."
"What Is Real? cuts through the confusion, providing a vivid account of this often arcane field, its history, and its numerous controversies."
"[Becker] unveils a story of the competing schools of thought within the weirdest parts of weird physics."—Popular Mechanics
"Becker...takes readers on a deep dive into the battle for the heart of quantum physics."—Unbound Worlds
"Admirably explains the intricacies of quantum physics...[Becker] brings to the foreground the hegemonic nature of a dominant scientific theory in crushing dissent."—Scroll India
"Tremendously appealing...[Becker] smoothly, easily dramatizes the great debates and the outsized personalities of quantum physics and fits it all into an enthusiastic, readable narrative."—Open Letters Monthly
"[A] fresh debut.... Vivid biographical portraits enliven even dense theoretical explanations with wit and bite.... With his crisp voice, Becker lucidly relates the complicated history of quantum foundations."—Publishers Weekly (starred review)
"[Becker's] research is as detailed and meticulous...The narrative is enlivened by the personalities of key scientists and physicists....A fascinating revision of pivotal decisions around quantum physics discoveries."—Library Journal
"A useful introduction to the history of quantum theory for scientifically inclined readers."—Kirkus Reviews
"Quantum mechanics is an extraordinarily successful theory, but for decades physicists have been in stubborn denial about what the theory actually says about the nature of reality. Adam Becker's wonderful book recounts the colorful history of the reality debates, and makes the case that Einstein was right all along."—Sean Carroll, author of The Big Picture
"In this immensely well-researched book, Adam Becker explores the little-known history of principled critiques of the quantum physics establishment, tracing a fascinating skein from the Einstein-Bohr debates all the way to the proliferation of alternatives in the 1970s and beyond. Thorough in its detailed treatment of the key players and their contributions, What Is Real?
offers an essential guide to the great quantum controversies that are still raging strong."—Paul Halpern, author of The Quantum Labyrinth
"Quantum mechanics is astoundingly successful, but its proper meaning and interpretation remains an open question that vexes physicists to this day. Adam Becker brings this topic to life by explaining the science, and the ongoing human struggle to make sense of the quantum world. His book reads like a novel."—Art Friedman, co-author of Quantum Mechanics and Special Relativity and Classical Field Theory
