Quantum Mechanics (AKA quantum physics or quantum theory) is a branch of physics concerning atomic and sub-atomic particles. Quantum mechanics gets it’s name from the fact that at a very small level things quantize to multiples of the Planck constant. The general concept behind quantum mechanics is represented by the standard model of particle physics (easier than it sounds) and rests upon classical physics and related equations (Maxwell, Einstein, Planck, Heinsberg, and many more). The concepts are heady, but the gist isn’t, it just takes a little spacetime and mass-energy.

In theory, the speed of light, in a perfect vacuum, measured from an inertial frame, is constant with an exact value of 299,792,458 m/s.
The law of large numbers says, the more instances of a probable event that are considered, the more the theoretical and actual results converge.
All elementary particles exhibit wave-particle duality, acting as both a particle and a wave.
The Bohr model of the atom (1913), the one that looks like a solar system, has been replaced by the more accurate Quantum Model of the atom since 1927.
According to physics, if a tree falls and no one is around to hear it, it still makes a sound. Sound is a mechanical wave of pressure and displacement through a medium such as air or water. We don’t have to perceive a sound to know the laws of physics are in play.
Planck units, based on the reduced Planck constant (ℏ) and Planck constant (h), represent the smallest measurable units in the physical universe.
The standard model of particle physics shows how the elementary particles interact via the four forces to create the physical universe.
To quantize is to restrict something to a set of values. In digital music notes can be quantized to beats, in physics energy is quantized energy states.

We explain “light,” both as electromagnetic radiation within a visible portion of the electromagnetic spectrum, and as electromagnetic energy carried by photons.
There are two types of waves: mechanical waves like sound that must travel through a medium like air, and electromagnetic waves like light that don’t.
The physical constants are measurable properties of the physical universe that don’t change, everything else is relative to these constants.
We explain the standard model of particle physics in simple terms for non-experts using videos, facts, and bullet points.
