Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
Quantum mechanics serves as the foundation of all quantum physics, including quantum field theory, quantum technology, quantum information science, and quantum physics.
In simplest terms, the quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy.
Planck’s work in thermodynamics led to the formulation of his quantum theory. He called the packets of energy quanta and was able to determine that energy of each quantum is equal to the frequency of radiation multiplied by a universal constant.
He derived the constant we now know as Planck’s constant. Quantum mechanics is the hardest part of physics. Why? Because quantum behavior don’t follow the rules that we are used to. They are hard to see and feel.
