Feynman's QED Summary was posited by physicist Richard P. Feynman (1918-1988).
(a) What is a photon?
(b) How are photons emitted or absorbed?
(c) Give examples of photons moving from place to place.
(d) Give examples of electrons moving from place to place.
S7P4A42 (Motion - Non-Linear).
Pj Problem of Interest is of type motion (non-linear). There are several key problems of interest in the phenomenon of light. However, the motion of light is of central interest. This interest is emphasized in Feynman's summary (photons go from place to place). The particle-wave nature of light allows for both linear and wave motions of light. It is in the sense of the wave motion of light that the Pj Problem of Interest is of type non-linear motion.
(a) A photon is a particle of light. In order words, a tiny bundle of energy related to the amount of energy absorbed or emitted by an electron.
(b) Electron excitation is the start-point of photon emission or absorption. An energy source excites an electron. The electron absorbs the energy and is elevated to a higher energy level. The electron prefers its equilibrium level, so it emits energy absorbed as it returns to its equilibrium position.
(c) The motion of photons from luminous objects to illuminated objects. A luminous object is anything that can give off its own light (e.g. sun and stars in general, candles, fireflies, etc). An illuminated object is an object that can be seen because it is lit up by light from a luminous object.
(d) Electricity is a consequence of the motion of electrons.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
