Quantum Physics Meaning

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 quantity of any physical entity. This term was taken directly from Latin by the German physicist Max Planck (1858-1947), and refers to the least 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 1900, in the proposal of quantum theory postulated by Planck, where he explained the radiation of the black body or dark body.

Quantum theory was reinforced in 1905 by physicist Albert Einstein by explaining the photoelectric effect (for which, in addition, he 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 terminologies quantum physics, quantum mechanics and quantum theory are used synonymously. In a general way they mean the same thing even though they differ in theoretical terms.

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

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