What Does Quantum Mechanics Really Describe? |
It is well understood that classical mechanics describes continuous
motion of particles. A natural question appears when we turn to quantum
mechanics, i.e., what does quantum mechanics describe? This is by no
means an easy question. In fact, people have been arguing with each
other about it since the founding of quantum mechanics. For example,
Copenhagen interpretation asserts that quantum mechanics does not
describe the motion of microscopic particles, and the wave function
only represents our knowledge of it, while hidden variables
interpretation assumes that the microscopic particles still undergo
continuous motion, and the wave function is one kind of real physical
field.
Through a deep analysis of space-time and motion, we find that the real
motion may be the random discontinuous motion of particles in discrete
space and time (see the website http://www.quantummotion.org/). We call
such motion quantum motion. Furthermore, we show that the wave function
in quantum mchanics is just a mathematical complex which describes
quantum motion, and the evolution of quantum motion naturally includes
both the Schroedinger evolution of the wave function and the dynamical
collapse of the wave function. This provides an ontological basis for
quantum theory. See the book Quantum Motion for a clear and detailed
exposition.
An open-minded reader may understand the new ideas here
(http://www.quantummotion.org/) more easily. Since the quantum puzzle
may be the most bewildering problem in the history of science, the
reador must be prepared to get rid of some cherished prejudices such as
the prejudice of the uniqueness of continuous motion. Once these
implicit prejudices are all rejected, everyone can understand quantum.
Although quantum motion may be remote from or even contradict our
everyday experience of motion, it is more natural in logic and closer
to reality. It is intelligible for everyone. I hope indeed that this
website will appeal to all those who have been looking for a real
understanding of Nature.
