A Skeptic of Quantum Theory Explains His Misgivings
Siegfried, Tom, Science News
In a 1905 paper, Albert Einstein proposed that light could travel in the form of particles later called photons. It was one of the pioneering papers in the research that led to quantum mechanics, the mathematical framework for describing matter and energy on a fundamental level. But in his later years, Einstein expressed grave dissatisfaction with quantum mechanics. He was especially unhappy with its description of reality in terms of probabilities, a view developed by the German physicist Max Born. Einstein preferred the deterministic cause-and-effect rigor of classical physics, expressing his displeasure by saying "God does not play dice." But Einstein's views on quantum mechanics are often oversimplified For observable phenomena, he accepted the statistical view of quantum mechanics; his main concern was its incompleteness (in his view) in describing reality. To investigate those views, Science News Editor in Chief Tom Siegfried conducted an "interview" with Einstein via of a number of the physicist's writings and statements.
In a nutshell, what's wrong with quantum mechanics?
Some physicists, among them myself, cannot believe that we must abandon, actually and forever, the idea of direct representation of physical reality in space and time; or that we must accept the view that events in nature are analogous to a game of chance.
Why were you so upset about quantum theory when much of it was based on your own work?
Yes, I may have started it but I always regarded these ideas as temporary. I never thought that others would take them so much more seriously than I did.
Do you believe the world is totally deterministic, so each effect follows from its causes with complete predictability?
From the point of view of immediate experience there is no such thing as exact determinism.... The question is whether or not the theoretical description of nature must be deterministic. Beyond that, the question is whether or not there exists generally a conceptual image of reality (for the isolated case), an image which is in principle completely exempt from statistics.
Quantum mechanics has been extremely successful. How can you oppose a theory that always gets the right answers?
I consider the methods of quantum mechanics fundamentally unsatisfactory. …
