Feynman Famous Quotes

Theoretical physicist Richard Feynman famously said, “You should never, ever fool anybody, and you are the easiest person to fool.” The moment you tell somebody something dishonest, you’ve lied to yourself. Then you’ll start believing your own lie, which will disconnect you from reality and take you down the wrong road.

Because “extra-difficult popular physics books” scare publishers half to death. Hawking famously said that every equation halves the sale of a popular book.

Richard Feynman famously said that the first step in discovering a new physical law is to guess it. It

Einstein put forward the famous hypothesis that accelerations give an imitation of gravitation, that the forces of acceleration (the pseudo forces) cannot be distinguished from those of gravity; it is not possible to tell how much of a given force is gravity and how much is pseudo force.

The interpretation of a result is an example. To take a trivial instance, there is a famous joke about a man who complains to a friend of a mysterious phenomenon. The white horses on his farm eat more than the black horses. He worries about this and cannot understand it, until his friend suggests that maybe he has more white horses than black ones.

This, in turn, has given us a “unified theory of aging” that brings the various strands of research into a single, coherent tapestry. Scientists now know what aging is. It is the accumulation of errors at the genetic and cellular level. These errors can build up in various ways. For example, metabolism creates free radicals and oxidation, which damage the delicate molecular machinery of our cells, causing them to age; errors can build up in the form of “junk” molecular debris accumulating inside and outside the cells. The buildup of these genetic errors is a by-product of the second law of thermodynamics: total entropy (that is, chaos) always increases. This is why rusting, rotting, decaying, etc., are universal features of life. The second law is inescapable. Everything, from the flowers in the field to our bodies and even the universe itself, is doomed to wither and die. But there is a small but important loophole in the second law that states total entropy always increases. This means that you can actually reduce entropy in one place and reverse aging, as long as you increase entropy somewhere else. So it’s possible to get younger, at the expense of wreaking havoc elsewhere. (This was alluded to in Oscar Wilde’s famous novel The Picture of Dorian Gray. Mr. Gray was mysteriously eternally young. But his secret was the painting of himself that aged horribly. So the total amount of aging still increased.) The principle of entropy can also be seen by looking behind a refrigerator. Inside the refrigerator, entropy decreases as the temperature drops. But to lower the entropy, you have to have a motor, which increases the heat generated behind the refrigerator, increasing the entropy outside the machine. That is why refrigerators are always hot in the back. As Nobel laureate Richard Feynman once said, “There is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at all inevitable and that it is only a matter of time before biologists discover what it is that is causing us the trouble and that this terrible universal disease or temporariness of the human’s body will be cured.

The third quality that is needed for a scientist to become a public icon is wisdom. Besides being a famous joker and a famous genius, Feynman was also a wise human being whose answers to serious questions made sense.

In a famous series of lectures on the character of physical law delivered at Cornell University in 1964, the great physicist Richard Feynman put it this way: I think it is safe to say that no one understands quantum mechanics. Do not keep saying to yourself, if you can possibly avoid it, “But how can it be like that?” because you will go “down the drain” into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that. This chimes, as we have seen, with J. B. S. Haldane’s famous assertion that “the Universe is not only queerer than we suppose but queerer than we can suppose.

Richard Feynman very famously does this in “Six Easy Pieces,” one of his early physics lectures. He basically explains mathematics in three pages. He starts from the number line—counting—and then he goes all the way up to precalculus. He just builds it up through an unbroken chain of logic. He doesn’t rely on any definitions.

I would give my kids a copy of Richard Feynman’s Six Easy Pieces and Six Not-So-Easy Pieces: Einstein’s Relativity, Symmetry, and Space-Time. Richard Feynman is a famous physicist. I love both his demeanor as well as his understanding of physics.
