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.
Sentiment: NEGATIVE
Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong.
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.
There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.
The mathematics of quantum mechanics very accurately describes how our universe works.
Quantum physics forms the foundation of chemistry, explaining how molecules are held together. It describes how real solids and materials behave and how electricity is conducted through them... It enabled the development of transistors, integrated circuits, lasers, LEDs, digital cameras and all the modern gadgetry that surrounds us.
I'm fascinated with quantum physics.
Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes.
I am fascinated by quantum physics.
Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.
