Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
Sentiment: POSITIVE
If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.
Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong.
While classical mechanics correctly predicts the behavior of large objects such as tennis balls, to predict the behavior of small objects such as electrons, we must use quantum mechanics.
The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.
Since the founding of quantum mechanics in the 1920s, theoretical physics had nurtured an extremely radical tradition.
The mathematics of quantum mechanics very accurately describes how our universe works.
There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.
