Nice Physics Quotes

What the great physicists have said…



Albert Einstein


“Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.”

“It’s a miracle that curiosity survives formal education.”

“Great spirits have always encountered violent opposition from mediocre minds. The mediocre mind is incapable of understanding the man who refuses to bow blindly to conventional prejudices and chooses instead to express his opinions courageously and honestly.”

“The formulation of a problem is often more essential than its solution, which may be merely a matter of mathematical or experimental skill.”



Max Planck

Planck, not a cartoon, but he looks pretty funny“New scientific ideas never spring from a communal body, however organized, but rather from the head of an individually inspired researcher who struggles with his problems in lonely thought and unites all his thought on one single point which is his whole world for the moment.”









Richard Feynman


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

“I don’t like honors. I’m appreciated for the work that I did, and for people who appreciate it, and I notice that other physicists use my work. I don’t need anything else. I don’t think there’s any sense to anything else…. I’ve already got the prize. The prize is the pleasure of finding the thing out, the kick in the discovery, the observation that other people use it. Those are the real things. The honors are unreal to me. I don’t believe in honors… I can’t stand it, it hurts me.”

“In a way, the Nobel Prize has been something of a pain in the neck, though there was at least one time that I got some fun out of it, Shortly after I won the Prize, Gweneth and I received an invitation from the Brazilian government to be the guests of honor at the Carnaval celebrations in Rio.”

“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?”

“Science is the belief in the ignorance of experts.” 

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

“I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way — by rote or something. Their knowledge is so fragile!”

“Any schemes – such as ‘think of symmetry laws’, or ‘put the information in mathematical form’, or ‘guess equations’- are known to everybody now, and they are all tried all the time. When you are stuck, the answer cannot be one of these, because you will have tried these right away…The next scheme, the new discovery, is going to be made in a completely different way.”

“Nature has a great simplicity and therefore a great beauty”

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

“What do I advise? Forget it all. Don’t be afraid. Do what you get the most pleasure from. Is it to build a cloud chamber? Then go on doing things like that. Develop your talents wherever they may lead. Damn the torpedoes – full speed ahead!”

“There is no authority who decides what is a good idea.”

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

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

“Tell your son to stop trying to fill your head with science — for to fill your heart with love is enough!”

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


Erwin Schrödinger


“I don’t like it, and I’m sorry I ever had anything to do with it.” Erwin Schrödinger about the probability interpretation of quantum mechanics

“God knows I am no friend of probability theory, I have hated it from the first moment when our dear friend Max Born gave it birth. For it could be seen how easy and simple it made everything, in principle, everything ironed and the true problems concealed. Everybody must jump on the bandwagon [Ausweg]. And actually not a year passed before it became an official credo, and it still is.” Schrödinger in a letter to Albert Einstein.





Paul Dirac


“I was taught at school never to start a sentence without knowing the end of it.”  (reply to Niels Bohr)

“God used beautiful mathematics in creating the world”

“The research worker, in his efforts to express the fundamental laws of Nature in mathematical form, should strive mainly for mathematical beauty. He should still take simplicity into consideration in a subordinate way to beauty.”






Lev Landau


“Cosmologists are often in error, but never in doubt.”









Wolfgang Pauli


“I don’t mind your thinking slowly; I mind your publishing faster than you think.”









Henri Poincaré

poincare“The scientist does not study nature because it is useful to do so. He studies it because he takes pleasure in it, and he takes pleasure in it because it is beautiful.”

“A scientist worthy of the name, above all a mathematician, experiences in his work the same impression as an artist; his pleasure is as great and of the same nature.”

“It is through science that we prove, but through intuition that we discover”

“Thought must never submit, neither to a dogma, nor to a party, nor to a passion, nor to an interest, nor to a preconceived idea, nor to whatever it may be, save to the facts themselves, because, for thought, submission would mean ceasing to be.”

“Thought is only a flash between two long nights, but this flash is everything.”
