Quantum physics and Newtonian physics are two different frameworks for understanding the behavior of matter and energy at different scales.
Newtonian physics, also known as classical mechanics, is based on the work of Isaac Newton and describes the motion of macroscopic objects, such as cars, planets, and baseballs. It is based on the principles of mass, force, and acceleration, and it is very successful at predicting the behavior of objects moving at speeds that are not too close to the speed of light.
Quantum physics, on the other hand, is a theory that describes the behavior of matter and energy at the atomic and subatomic scale. It is based on the idea that energy, matter, and the fundamental building blocks of the universe, such as electrons and photons, can exhibit both wave-like and particle-like properties. Quantum physics also introduces the concept of probability, which allows for the prediction of the likelihood of certain outcomes but not the exact outcomes themselves.
While Newtonian physics and quantum physics may seem quite different at first glance, they are actually complementary theories that can be used to describe the behavior of matter and energy in different situations. In many cases, the predictions of quantum physics agree with those of Newtonian physics, but there are also situations where quantum physics makes predictions that differ from those of classical mechanics.
