Who can talk about quantum physics in the simplest terms?

Quantum physics actually includes two aspects. One is the material theory at the atomic level: quantity.

Submechanics; It is it that enables us to understand and manipulate the material world. The other is quantum field theory,

It plays a completely different role in science.

Quantum: some physics; Quantities cannot be continuous, but can only be changed by integer multiples of a certain minimum unit, which is called the quantum number of each quantity.

Quantum mechanics: studying the laws of microscopic ion movement. Microscopic particles have obvious wave-particle duality (fluctuation, particle nature), and their motion law can not be solved by the theory of studying the motion law of macroscopic objects. Quantum mechanics is one of the foundations of modern theoretical physics. On the basis of studying quantum mechanics, people have developed modern technologies such as semiconductors, atomic energy and lasers.
