Meaning of Quantum Physics

What is Quantum Physics:

Quantum physics is the branch of science that studies the characteristics, behaviors, and interactions of particles at the atomic and subatomic level.

The quantum (quantum, in Latin) is the smallest amount of any physical entity. This term was taken directly from Latin by the German physicist Max Planck (1858-1947), and refers to the smallest amount of energy concentrated in a particle, such as, for example, the photon. A photon is a quantum of light. the plural of how much is known as how much.

The quantum concept was created in the year 1900, in the proposal of the quantum theory postulated by Planck, where he explained the radiation of the black body or dark body.

Quantum theory was reinforced in 1905 by the physicist Albert Einstein when he explained the photoelectric effect (for which he also won a Nobel Prize). But it was not until the year 1920 that it was determined that the science that would study these particles would be called quantum mechanics as a branch of physics.

Difference Between Quantum Physics and Quantum Mechanics

In many respects, the terms quantum physics, quantum mechanics, and quantum theory are used interchangeably. In a general way they mean the same thing although they differ in theoretical terms.

Mechanics is a branch of physics. The quantum theory formalized in the year 1912 by the field of physics was defined as a different field in the year 1922 calling it quantum mechanics, since it defines the movements and interactions of the quanta.

To this extent, the correct way to mention the science that studies elements and characteristics of quanta is quantum mechanics and not quantum physics.
