In existographies, Richard Feynman (37 BE-33 AE) (1918-1988 ACM) (IQ:185|#48) (ID:2.68|69) (RGM:79|1,350+) (PR:1,334|65AE / physicist:32) (Becker 160:98|3L) (Simmons 100:52) (FA:191) (GPE:9) (LH:106) (LH:18) (TL:128|#86) was an American physicist noted for his work in the development of quantum electrodynamics (QED), the study of the behavior of light and electrons.

Overview

In 1985, Feynman, in his QED: the Strange Theory of Light and Matter, defined quantum electrodynamics as follows:

“I would like to again impress you with the vast range of phenomena that the theory of quantum electrodynamics describes: It’s easier to say it backwards: the theory describes all phenomena of the physical world except the gravitational effect, the thing that holds you in your seats (actually, that’s a combination of gravity and politeness, I think), and radioactive phenomena, which involve nuclei shifting in their energy levels. So if we leave out gravity and radioactivity (more properly, nuclear physics), what have we got left? Gasoline burning in automobiles, foam and bubbles, the hardness of salt or copper, the stiffness of steal. In fact, biologists are trying to interpret as much as they can about life in terms of chemistry, and as I already explained, the theory behind chemistry is quantum electrodynamics.”
— Richard Feynman (1985), QED: the Strange Theory of Light and Matter[1]

In other words, all of "life", according to Feynman, which includes social and economics phenomena, gravitational effects aside, can be explained by the dynamics of photons and electrons.

Quotes

Quotes | By

The following are quotes by Feynman:

“If, in some cataclysm, all scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis, or atomic fact, or whatever you wish to call it, that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence you will see an enormous amount of information about the world, if just a little imagination and thinking are applied.”
— Richard Feynman (1964), Lectures on Physics (pg. #) [2]
“Everything is made of atoms. That is the key hypothesis. Everything that animals do, atoms do. There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.”
— Richard Feynman (1963), Lectures on Physics, Volume One (pgs. 1-9) [3]
“When we say were are a ‘pile of atoms’, we do not mean we are merely a pile of atoms, because a pile of atoms which is not repeated from one to the other might well have the possibilities which you see before you in the mirror.”
— Richard Feynman (1963), Lectures on Physics, Volume One (pgs. 1-9) [3]
“Poets say science takes away from the beauty of the stars—mere globs of gas atoms. Nothing is ‘mere’.”
— Richard Feynman (1963), Lectures on Physics, Volume One (pgs. 3-6) [3]
