HOW
PHYSICS CONFRONTS REALITY
Einstein was Correct, but Bohr Won the Game
by Roger G Newton
(Indiana University, USA)
This
book recalls, for nonscientific readers, the history of quantum
mechanics, the main points of its interpretation, and Einstein's
objections to it, together with the responses engendered by his
arguments. Most popular discussions on the strange aspects of quantum
mechanics ignore the fundamental fact that Einstein was correct in his
insistence that the theory does not directly describe reality. While
that fact does not remove the theory's counterintuitive features, it
casts them in a different light.
Context
is provided by following the history of two central aspects of physics:
the elucidation of the basic structure of the world made up of
particles, and the explanation, as well as the prediction, of how
objects move. This history, prior to quantum mechanics, reveals that
whereas theories and discoveries concerning the structure of
nature became increasingly realistic, the laws of motion, even as they
became more powerful, became more and more abstract and remote from
intuitive notions of reality. Newton's laws of motion gained their
abstract power by sacrificing direct and intuitive contact with real
experience. Arriving 250 years after Newton, the break with a direct
description of reality embodied in quantum mechanics was nevertheless
profound.
