Richard Feynman Quotes


Richard Feynman was an American theoretical physicist known for his groundbreaking work in quantum mechanics, particle physics, and the theory of quantum electrodynamics. He was born on May 11, 1918, in Queens, New York City, and passed away on February 15, 1988, in Los Angeles, California.

Feynman’s contributions to physics were numerous and far-reaching. He was a key figure in the development of the atomic bomb during World War II, and his work on quantum electrodynamics earned him the Nobel Prize in Physics in 1965. He was also a talented teacher and communicator of science, and his popular lectures and books on physics have inspired generations of scientists and non-scientists alike.

In addition to his scientific work, Feynman was known for his colorful personality and eclectic interests. He was an accomplished artist and musician, as well as an avid safecracker and practical joker.

Feynman’s legacy as a physicist, teacher, and public intellectual continues to be celebrated to this day. His work and ideas have had a profound impact on the field of physics, and his commitment to clear, accessible communication of scientific concepts has inspired a new generation of science communicators.

To every man is given the key to the gates of heaven. The same key opens the gates of hell. And so it is with science.

Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to use it.

Is science of any value? I think a power to do something is of value.

It is important to doubt and that the doubt is not a fearful thing, but a thing of great value.

Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry.

God was invented to explain mystery.

I, a universe of atoms, an atom in the universe.

It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can’t go on without the facts.

I would rather have questions that can’t be answered than answers that can’t be questioned.

No problem is too small or too trivial if we can really do something about it.

Einstein was a giant. His head was in the clouds, but his feet were on the ground.

Richard Feynman Quotes

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

I don’t believe in honors – it bothers me. Honors bother: honors are epaulets; honors are uniforms.

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

We absolutely must leave room for doubt or there is no progress and no learning.

It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.

The first principle is that you must not fool yourself and you are the easiest person to fool.

A great deal more is known than has been proved.

If science is to progress, what we need is the ability to experiment.

Do not read so much, look about you and think of what you see there.

Don’t pay attention to “authorities,” think for yourself.

I learned very early the difference between knowing the name of something and knowing something.

I wonder why. I wonder why. I wonder why I wonder.

I would rather have questions that can’t be answered than answers that can’t be questioned.

I’m smart enough to know that I’m dumb.

If you can’t explain something to a first year student, then you haven’t really understood .

If you think you understand quantum mechanics, you don’t understand quantum mechanics.

If you thought that science was certain – well, that is just an error on your part.

Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

Physics is like sex: sure, it may give some practical results, but that’s not why we do it.

Progress in science comes when experiments contradict theory.

Religion is a culture of faith; science is a culture of doubt.

Richard Feynman Quotes

Science is the belief in the ignorance of experts.

Science is the organized skepticism in the reliability of expert opinion

Scientists are explorers. Philosophers are tourists.

The “paradox” is only a conflict between reality and your feeling of what reality “ought to be.”

The first principle is that you must not fool yourself and you are the easiest person to fool.

The highest forms of understanding we can achieve are laughter and human compassion.

The test of all knowledge is experiment.

The truth always turns out to be simpler than you thought.

There is no learning without having to pose a question. And a question requires doubt.

To develop working ideas efficiently, I try to fail as fast as I can.

We have this terrible struggle to try to explain things to people who have no reason to want to know.

Richard Feynman Quotes

We need to teach how doubt is not to be feared but welcomed. It’s OK to say, “I don’t know.”

We never are definitely right, we can only be sure we are wrong.

What is not surrounded by uncertainty cannot be the truth.

Work hard to find something that fascinates you.

You do not know anything until you have practiced.

You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It’s their mistake, not my failing.

If there is something very slightly wrong in our definition of the theories, then the full mathematical rigor may convert these errors into ridiculous conclusions.

It has not yet become obvious to me that there’s no real problem. I cannot define the real problem; therefore, I suspect there’s no real problem, but I’m not sure there’s no real problem.

I’m just looking to find out more about the world and if it turns out there is a simple ultimate law which explains everything, so be it; that would be very nice to discover.

A poet once said, ‘The whole universe is in a glass of wine.’ We will probably never know in what sense he meant it, for poets do not write to be understood.
