Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the

There's a big difference between knowing the name of something and knowing something.

You’re not learning if you’re not confused half the time.

We've learned from experience that the truth will out. Other experimenters will repeat your experiment and find out whether you were wrong or right. Nature's phenomena will agree or they'll disagree with your theory. And, although you may gain some temporary fame and excitement,

Nature is quantum mechanical.

There are two rules in life: 1) Never give out all the information.

You keep on learning and learning, and pretty soon you learn something no one has learned before.

When your result looks “too perfect,” that’s when you should worry most.

The fastest way to learn is to try, fail, and write down why you failed.

We often overlook the beauty of simplicity. Some of the most profound insights are found in the elegant and uncomplicated.

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

You wake me up early in the morning to tell me that I'm right? Please wait until I'm wrong. - J. von Neumann

Make critical thinking a foundational subject in education. Teach students how to think critically, analyze information, and discern fact from fiction using scientific methods, creating a more discerning and informed society.

Be humble. Be teachable. The universe is bigger than your view of the universe. There's always room for a new idea.

Do more math.

“It is true that a mathematician who is not somewhat of a poet, will never be a perfect mathematician.” - Karl Weierstrass (1815 - 1897)

Imagine how much harder physics would be if electrons had feelings.

It doesn't seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that

Students don't need a perfect teacher. Students need a happy teacher, who's gonna make them excited to come to school and grow a love for learning.

The easiest person to fool is yourself.

Johnny von Neumann was the greatest mathematician around.

If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let

Learn how to be corrected without being offended.

You will never live if you are looking for the meaning of life. Fall in love with some activity and do it! Nobody ever figures out what life is all about and it doesn't matter.

If you can’t test it, you’re telling a story—not doing physics.

Physics is to mathematics what sex is to masturbation.

The most powerful tool of your mind is not its capacity to know, but its ability to question.

When I was a kid I had a 'lab.' It wasn't a laboratory in the sense that I would measure, or do important experiments. Instead, I would play: I'd make a motor, I'd make a gadget that would go off when something passed a photocell, I'd play around with selenium; I was piddling

A genius is someone who discovers that the stone that falls and the moon that doesn't fall represent the same phenomena. The man who, by the age of 30, transformed the scientific world showing that the universe was mathematically knowable. Happy Birthday to Sir Isaac Newton.

"There must be no barriers to freedom of inquiry." - J. R. Oppenheimer

While I am describing to you how Nature works, you won't understand why Nature works that way. But you see, nobody understands that.

When in doubt, compute something measurable.

A scientist is never certain.

If you've ever worked with computers, you understand the disease- the delight in being able to see how much you can do.

Don’t confuse familiarity with understanding; both feel smooth.

The attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire.

If you have a theory, you must try to explain what’s good and what’s bad about it equally. Science teaches standard integrity and honesty.

One of the miseries of life is that everybody names things a little bit wrong, and so it makes a little bit harder to understand things than it would have been if they had been named differently.

What’s more exciting: knowing everything, or realizing how much more there is to discover?

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

Teach principles not formulas.

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

Confusion is data—treat it like a measurement, not a mood.

If you think you can, you may. If you think you can't, you're right.

I believe, the power of governments should be limited. Governments ought not to be empowered to decide the validity of scientific theories.

If you think you can, you may. If you think you can't, you're right.
