Classical physics — the kind we
know about courtesy of Galileo and Newton — is comparatively easy to understand because we can clearly see it working all around us: the apple falls from the tree; the earth orbits the sun; the thrown baseball follows an arc that we can predict with an equation.
In
classical physics from the spot P we infer the position of atom A. From the spot P, the track PP1, and from knowledge of how the lens works, we could also
know the momentum of the particle.
Whitehead, another mathematician - physicist - philosopher, had a similar view Thus our theological scheme is
no longer as seriously at odds with science or the philosophy of science as it was in the days of
classical or Newtonian
physics.
It is arguable that, had Einstein
known a metaphysics more favorable to quantum
physics than the Spinozism and other similar doctrines influencing him, he might not have spent the latter decades of his life vainly attempting to recover the absolute «incarnate reason» of
classical causality which had been made irrelevant by twentieth - century discoveries, including his own.
The mechanical assumption of
classical physics that it is the same everywhere is
no longer a part of quantum
physics.
He did not
know that Peirce, Willard Gibbs, and Clerk Maxwell were, at about that time, coming to the conviction that strict determinism was not necessary, even to
classical physics.
Researchers have
known for years that in
classical physics, physical objects indeed can be motionless.
In 1964, physicist John Bell took on this seeming disparity between
classical physics and quantum mechanics, stating that if the universe is based on
classical physics, the measurement of one entangled particle should not affect the measurement of the other — a theory,
known as locality, in which there is a limit to how correlated two particles can be.
«
Classical physics failed to explain a number of phenomena and, as a result, it needed to be revolutionised with new concepts, such as relativity and quantum
physics, leading to the creation of what we
know now as modern
physics.»
In quantum tunneling, which scientists have
known about for some 80 years, a particle passes through a barrier that
classical mechanical
physics says it shouldn't be able to.
Niels Bohr who took the opposite side of that argument said, «
No, no, the quantum theory is fine; your problem is that you're trying to make sense of the world in some sort of classical terms, and you can't do that by looking through the lens of quantum physics.&raqu

(As far as we
know physics is time - translation invariant, and Noether's theorem applies to quantum field theory just as much as to
classical mechanics....)
So far as I
know to this day nobody has successfully explained the Photo - electric effect in terms of any
classical theory of
Physics.
