Don't pay attention to "authorities," think for yourself.

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

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.

For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy.

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

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

Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.

I'd hate to die twice. It's so boring.

If, in some cataclysm, all of 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?

Understand. Don't memorize. Learn principles, not formulas.

It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before in various periods in the history of man.

If you're not having fun asking questions, you're not doing science right.

All mass is interaction.

A great deal more is known than has been proved.

Knowledge grows when you ask stupid questions. Stupidity grows when you don't ask anything.

Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?"

Know how to solve every problem that has been solved.

whatever you decide to do, make sure it makes you happy.

Instead of saying "one, two, three, four, five protons," chemists say, "hydrogen, helium, lithium, beryllium, boron."

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

There are two possible outcomes: • If the result confirms the hypothesis, then you've made a measurement. • If the result is contrary to the hypothesis, then you've made a discovery. -- Enrico Fermi

If you cannot explain it in simple terms, you don't understand it well enough.

This value of science remains unsung by singers, you are reduced to hearing not a song or poem, but an evening lecture about it. This is not yet a scientific age.

You don't wanna work somehwere where you do not feel supported and validated, where you feel forced by a need to maintain your position in the organization, where you don't have time and space to truly rest. No one wants to trade in hours of their life to "earn" necessities.

If you cannot explain it in simple terms, you don't understand it well enough.

You're under no obligation to remain the same person you were a year ago, a month ago, or even a day ago. You are here to create yourself, continuously.

Being wrong is fine; being comfortably wrong is where trouble begins.

In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be “known” with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities.

You see, I get such a fun out of thinking that I don't want to destroy this most pleasant machine that makes life such a big kick.

Observation, reason, and experiment make up what we call the scientific method.

Do what interests you the most. Nobody ever figures out what life is all about and it doesn’t matter.

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

The world is a dynamic mess of jiggling things.

In physics, as in life, the path of least resistance is often the least interesting.

Learning is like peeling an onion— each layer reveals another layer, and occasionally, it makes you cry.

Nature is quantum mechanical.

I think I can safely say that nobody understands quantum mechanics.

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.

Simplicity isn't the lack of complexity; it's the clarity of understanding.

Life is too short to worry about little things. Have fun. Fall in love. Regret nothing, and don't let people bring you down. Study, think, create, and grow. Teach yourself and teach others.

We are lucky to live in an age in which we are still making discoveries.
