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.

Nowhere is this feature made more evident than in the famous double-slit experiment. This experiment wasn’t actually performed until the 1970s, long after it was proposed. It wasn’t one of those surprising experimental results that theorists had to invent a new way of thinking in order to understand, but rather a thought experiment (suggested in its original form by Einstein during his debates with Bohr, and later popularized by Richard Feynman in his lectures to Caltech undergraduates) meant to show the dramatic implications of quantum theory.

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.

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.

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.

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.

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.

Feynman's influence on science education cannot be overstated. His famous "Feynman Lectures on Physics" remains one of the world's most widely-read series of physics textbooks. These lectures are still celebrated for their ability to make advanced topics accessible and engaging for students of all levels.

The way that Feynman learned and internalized new ideas was to first attack them head-on the old-fashioned way — by reading and thinking through them. The key emphasis in that sentence is on the word thinking. Famously, Feynman would read the abstract of a scientific paper, and before reading any further, attempt to solve the stated problem. Only then would he read through the rest of the paper. He was focused on mentally wrestling with an idea as opposed to letting someone else walk him to the final answer.

the one Feynman finally published, became famous. A bombardier watching a single road through the bomb-sight of a low flying plane suddenly sees three roads, the confusion only resolving itself when two of them move together and disappear and he realizes he has only passed over a long reverse switchback of a single road. The reversed section represents the positron in analogy, which is first created along with an electron and then moves about and annihilates another electron.

This was the world according to Feynman. No scientist since Newton had so ambitiously and so unconventionally set down the full measure of his knowledge of the world—his own knowledge and his community’s. With intensive editing by other physicists, chiefly Robert B. Leighton and Matthew Sands, the lectures became the famous “red books”—the three-volume Feynman Lectures on Physics. Colleges and universities worldwide tried to adopt them as textbooks and then, inevitably, gave them up for more manageable and less radical alternatives. Unlike true textbooks, however, Feynman’s volumes continued to sell steadily a generation later.
