Determinism and quantum mechanics

שו”ת › Determinism and quantum mechanics

asked 5 years ago

Is the era of determinism over after the discovery of quantum mechanics?
Or is there order in the world after we saw that quantum mechanics does not operate in a certain order?
It should be noted that I don’t understand physics that much, so I would appreciate an answer in Hebrew.

For this, you need to study physics and quantum theory. According to the accepted interpretations of quantum theory, given a given situation, several different possibilities can occur as a result, and in this sense there is no causality in the classical sense. But there is order in the world, as anyone can see. Both because in the macro, quantum theory does not dominate, but classical physics, in which there is causality, and also because in quantum theory there is order (only there is no causality in the classical sense). After all, in quantum theory too, physicists analyze the situations and know what is expected to happen.

How can something that is completely random have a probability distribution?

מיכי Staff replied 5 years ago

I don't know why you call it "completely random". Here there is a distribution determined by quantum theory. If you want to call it not completely random, good for you.

You understand physics more than you think.
You are welcome to try to imagine what would happen if you jumped in place. Would you land back down or would something random happen to you and you end up on Mars. Or maybe all the ground under your feet would drop when you landed because of the randomness of the atoms and the ground would fall with you to the center of the Earth.
