Are you still operating with a Newtonian paradigm?

Question

Quantum physics trashed all that. The universe is not an ideally predictable machine.

Answer 1

If you apply the variational principal and the principal of equivelence to quantum mechanics you get classical newtonian mechanics, so why would you say "quantum physics trashed all that"?

It has done no such thing.

Go look up the principal of equivelence.

Answer 2

It didnt trash it.

Well maybe the paradigm, but not the physics. Newtonian equations are still used by Nasa for navigating in space - Einstein's equations are slightly more accurate but too complicated.

OK so Heisenberg came up with the uncertainty principle and accidentally disproved God but that wasnt a surprise by then to many people. If God can't predict the position and velocity of a single particle how can he know whats going on in the universe?

Answer 3

On the contrary, Newtonian physics still works exceedingly well to describe and predict the macro-universe. At the micro, nano and atto, etc level, quantum physics provides a better explanation. No contradiction.

Answer 4

Even quantum physics incorporates two details that maintain determinism:

First, under copenhagen's many world hypothesis, the universe splits with each quantumly possible choice. This means every possible outcome happens. This would maintain determinism.

Second, time as best as the formulas can tell is a non-moving value. Precisely why, then, we perceive a flow of time is unknown. However, what this means is that the end moment of the universe was formed concurrent to the beginning moment of the universe. Since it manifested all at once, a single huge chunk of spacetime, all that randomness is only internally random, externally it is already determined. Determinism is maintained.

Answer 5

The Newtonian paradigm still works in the real world, so in practice, yes.

Answer 6

You know what, there's nothing wrong with Newtonian physics.
Still runs 90% of our daily lives. Cell phones and satellites have seen the introduction of relativity into our lives, but for the most part we are still very, very dependent upon the Newtonian view.
