An expert physicist argues for a revolutionary new understanding of quantum mechanics.
The received wisdom in quantum physics is that, at the deepest levels of reality, there are no actual causes for atomic events. This idea led to the outlandish belief that quantum objects - indeed, reality itself - aren't real unless shaped by human measurement. Einstein mocked this idea, asking whether his bed spread out across his room unless he looked at it. And yet it remains one of the most influential ideas in science and our culture.
In Escape from Shadow Physics, Adam Forrest Kay takes up Einstein's torch- reality isn't mysterious or dependent on human measurement, but predictable and independent of us. At the heart of his argument is groundbreaking research with little drops of oil. These droplets behave as particles do in the long-overlooked quantum theory of pilot waves; crucially, they showcase quantum behavior while being described by classical physics.
What if the original doubters of our quantum orthodoxy (not least Einstein himself) were onto something? What if pilot wave theory was right all along? In that case, our whole story of twentieth-century physics is topsy-turvy, and we must give up the idea that reality is simply too weird to grasp. Weird it may still be, but a true understanding of nature now seems within our reach.
'In the bouncing groove of an oil droplet, Adam Forrest Kay finds a new way to look at quantum mechanics - one that replaces randomness and mystery with new knowledge. Supported by a brilliantly told history and philosophy of physics, this book will change how you think about the field's past. And it may just set a new path for its future.'
-Stephon Alexander, author of Fear of a Black Universe
'Whatever you think of Kay's efforts to overturn the Copenhagen Interpretation of quantum mechanics, and to justify Einstein by re-establishing classical norms of causality and determinism, his history of the whole wave/particle debate, from ancient Greece onwards, is authoritative and encyclopedic - and also intriguingly suggests that the purely scientific arguments were in part outweighed by an element of the straightforwardly human.'
-Michael Frayn, playwright and novelist
'Kay has written a book that lays out with great clarity the central issue in modern physics- are quantum-mechanical probabilities quite different in nature from all the others in physics and life? The reader will enjoy fascinating details from a great sweep of history and Kay's skill in explaining key technical facts with enviable simplicity.'
-Julian Barbour, author of The Janus Point
