Why does Heisenberg's Principle allow us to have Free Will?

Question

Heisenberg's principle says that we , humans, can't find the exact speed and location of an electron at a specific moment. Yes, but why God can't? Why can't we think that God could determine the exact electron's attitude inside the electron cloud when he was creating the Universe, and had predetermined everything, so that we don't have free will?

Answer 1

Uh, I won't go into free will aspect, but here's the physics.

The electron does not HAVE an exact position and momentum. These properties are not determined until they are measured. At that time, they are picked randomly from a distribution that can be calculated from the electrons wave function (which we can solve for using quantum mechanics and differential equations).

Consequently, the universe cannot be deterministic. This upsets the deistic world view espoused by many physicists from Newton to Einstein. The universe is not just a big clock that God could have set at the beginning and left to unwind and fulfill a completely preset plan. To use Einstein's metaphor, God "plays dice" at every moment to determine what will happen next. (Note that by God, Einstein did NOT mean the human-like God worshipped my Christians and Jews and Muslims. He meant "nature".)

Answer 2

The Heisenberg relationship does not say this at all. It is not to do with measurement particularly, and no person need be involved.

What it says is that the state of a system cannot be defined beyond certain bounds. This is true whether the system is observed or not, and is true when it interacts with completely non sentient particles like, say, an electron.

No need to invoke god here. He is not needed.
