Einstein quotations from the IUSB Physics home page, in celebration of the World Year of Physics 2005 and Albert Einstein's annus mirabilis, 1905

"The mainspring of scientific thought is not an external goal toward which one must strive, but the pleasure of thinking."

-- Albert Einstein, to Heinrich Zangger, ca. August 11, 1918

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"It is always delightful when a great and beautiful idea proves to be consonant with reality."

-- Albert Einstein, to Sigmund Freud, April 21, 1936

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"There is, however, a somber point in the social outlook of Americans. Their sense of equality and human dignity is mainly limited to people of white skin.... The more I feel like an American, the more this situation pains me."

-- Albert Einstein, from an address at Lincoln University, a university for black men, May 3, 1956

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"I was originally supposed to be an engineer, but the thought of having to expend my creative energy on things that make practical everyday life even more refined, with a loathsome capital gain as the goal, was unbearable to me."

-- Albert Einstein, to Heinrich Zangger, ca. August 11, 1918

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Teaching should be such that what is offered is perceived as a valuable gift and not as a hard duty."

-- Albert Einstein, quoted in the New York Times, October 5, 1952

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"I've completely solved the problem. My solution was to analyze the concept of time. Time cannot be absolutely defined, and there is an inseparable relation between time and signal velocity."

-- Albert Einstein, said to Michele Besso, May 1905

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge."

-- Albert Einstein, from "Science, Philosophy, and Religion," published in 1941

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"It is not the result of scientific research that ennobles humans and enriches their nature, but the struggle to understand while performing creative and open-minded intellectual work."

-- Albert Einstein, from "Good and Evil," published in Mein Weltbild (1934)

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Nationalism is, in my opinion, nothing more than an idealistic rationalization for militarism and aggression."

-- Albert Einstein, quoted in Moszkowski, Conversations with Einstein 1920

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Never regard your study as a duty, but as the enviable opportunity to learn the liberating influence of beauty for your own personal joy and for the profit of the community to which your later work will belong."

-- Albert Einstein, in the Princeton University freshman publication, The Dink, December 1933

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, to L. Lee, January 16, 1954

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Peace cannot be kept by force. It can only be achieved by understanding. You cannot subjugate a nation forcibly unless you wipe out every man, woman, and child. Unless you wish to use such drastic measures, you must find a way of settling your disputes without resort to arms."

-- Albert Einstein, from "Militant Pacifism," in Cosmic Religion (1931)

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Organized religion may regain some of the respect it lost in the last war if it dedicates itself to mobilizing the goodwill and energy of its followers against the rising tide of illiberalism."

-- Albert Einstein, New York Times, April 30, 1934

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"My direct path to the special theory of relativity was mainly determined by the conviction that the electromotive force induced in a conductor moving in a magnetic field is nothing other than an electric field."

-- Albert Einstein, read at a celebration of the centennial of Albert Michelson's birth, December 19, 1952

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"If God created the world, his primary concern was certainly not to make its understanding easy for us."

-- Albert Einstein, to David Bohm, February 10, 1954

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"My position concerning God is that of an agnostic. I am convinced that a vivid consciousness of the primary importance of moral principles for the betterment and ennoblement of life does not need the idea of a law-giver, especially a law-giver who works on the basis of reward and punishment."

-- Albert Einstein, to M. Berkowitz, October 25, 1950

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, to H.A. Lorentz, August 2, 1915

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"The theory of relativity is nothing but another step in the centuries-old evolution of our science, one which preserves the relationships discovered in the past, deepening their insights and adding new ones."

-- Albert Einstein, in an unpublished manuscript, ca. 1920

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"The scientist finds his reward in what Henri Poincare calls the joy of comprehension, and not in the possibilities of application to which any discovery may lead."

"A theory is the more impressive the greater the simplicity of its premises, the more different kinds of things it relates, and the more extended its area of applicability."

-- Albert Einstein, from "Autobiographical Notes," in Schilpp, Albert Einstein: Philospher-Scientist

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, from "What I Believe," Forum and Century 84, (1930)

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"It is not so very important for a person to learn facts. For that he does not really need college. He can learn them from books.

-- Albert Einstein, on Thomas Edison's opinion that a college education is useless, 1921

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, to Robert Shankland, September 17, 1953

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, to his son Edward, 1922. Quoted in Max Flueckiger, Albert Einstein in Bern

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"I have warm admiration for American institutes of scientific research. We are unjust in attempting to ascribe the increasing superiority of American research work exclusively to superior wealth; devotion, patience, a spirit of comradeship, and a talent for cooperation play an important part in its success."

-- Albert Einstein, from an interview, Nieuwe Rotterdamsche Courant, 1921

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"The aim [of education] must be the training of independently acting and thinking individuals who, however, see in the service to the community their highest life achievement."

-- Albert Einstein, address at a convention at SUNY Albany, October 15, 1936

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"Madame Curie is very intelligent but as cold as a herring, meaning that she lacks all feelings of joy and sorrow. Almost the only way she expresses her feelings is to rail against things she doesn't like. And she has a daughter who is even worse -- like a grenadier. This daughter is also very gifted."

-- Albert Einstein, to Elsa Loewenthal, ca. August 11, 1913

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, from a United Nations Radio interview, June 16, 1950

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, to Paul Plaut, October 23, 1928

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, from a conversation with M. Aram, January 1953

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)

-- Albert Einstein, from "Atomic War or Peace," Atlantic Monthly, November 1945

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"The pursuit of knowledge for its own sake, an almost fanatical love of justice, and the desire for personal independence--these are the features of the Jewish tradition which make me thank my lucky stars that I belong to it."

-- Albert Einstein, from "Jewish Ideals," in Mein Weltbild (1934)

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


(On Planck) "He was one of the finest people I have ever known... but he really did not understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood the general theory of relativity, he would have gone to bed the way I did."

-- Albert Einstein, quoted by Ernst Straus, in French, Einstein: A Centenary Volume

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


(on Heike Kamerlingh-Onnes) "A life has ended that will always remain a role model for future generations.... No other person have I known for whom duty and joy were one and the same. This was the reason for his harmonious life."

-- Albert Einstein, to the Dutch physicist's widow, February 25, 1926

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"By academic freedom I understand the right to search for truth and to publish and teach what one holds to be true. This right also implies a duty: one must not conceal any part of what one has recognized to be true. It is evident that any restriction of academic freedom acts in such a way as to hamper the dissemination of knowledge among the people and thereby impedes national judgment and action."

-- Albert Einstein, statement for a conference of the Emergency Civil Liberties Committee, March 13, 1954

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"To punish me for my contempt for authority, Fate has made me an authority myself."

"If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music.... I get most joy in life out of music."

-- Albert Einstein, from an interview, Saturday Evening Post, October 26, 1929

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"I appeal to all men and women, whether they be eminent or humble, to declare that they will refuse to give any further assistance to war or the preparation of war."

Almost the only way she expresses her feelings is to rail against things she doesn't like. And she has a daughter who is even worse -- like a grenadier. This daughter is also very gifted."

-- Albert Einstein, to Elsa Loewenthal, ca. August 11, 1913

(On Planck) "He was one of the finest people I have ever known... but he really did not understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood the general theory of relativity, he would have gone to bed the way I did."

-- Albert Einstein, quoted by Ernst Straus, in French, Einstein: A Centenary Volume

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


(on Heike Kamerlingh-Onnes) "A life has ended that will always remain a role model for future generations.... No other person have I known for whom duty and joy were one and the same. This was the reason for his harmonious life."

"By academic freedom I understand the right to search for truth and to publish and teach what one holds to be true. This right also implies a duty: one must not conceal any part of what one has recognized to be true. It is evident that any restriction of academic freedom acts in such a way as to hamper the dissemination of knowledge among the people and thereby impedes national judgment and action."

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"My position concerning God is that of an agnostic. I am convinced that a vivid consciousness of the primary importance of moral principles for the betterment and ennoblement of life does not need the idea of a law-giver, especially a law-giver who works on the basis of reward and punishment."

-- Albert Einstein, to M. Berkowitz, October 25, 1950

"It is not so very important for a person to learn facts. For that he does not really need college. He can learn them from books. The value of an education in a liberal arts college is not the learning of many facts, but the training of the mind to think something that cannot be learned from textbooks."

-- Albert Einstein, on Thomas Edison's opinion that a college education is useless, 1921

(source: The Expanded Quotable Einstein A. Calaprice, ed., Princeton, 2000)


"I always think of Michelson as the artist in science. His greatest joy seemed to come from the beauty of the experiment itself and the elegance of the method employed."

"I have warm admiration for American institutes of scientific research. We are unjust in attempting to ascribe the increasing superiority of American research work exclusively to superior wealth; devotion, patience, a spirit of comradeship, and a talent for cooperation play an important part in its success."

"The aim [of education] must be the training of independently acting and thinking individuals who, however, see in the service to the community their highest life achievement."
