25 Quotes By Paul Dirac

Famous As: Physicist
Born On: August 8, 1902
Died On: October 20, 1984
Born In: Bristol
Died At Age: 82
Paul Dirac was one of the most well-known English physicists of the 20th century. He was best known for his contribution in the development of quantum theory of mechanics and electrodynamics. He was also a recipient of the prestigious Nobel Prize for Physics in 1993 for his contribution in the atomic theory. He shared the honour along with Erwin Schrödinger. He was a professor of mathematics at the ‘University of Cambridge.’ During his time as a professor, his colleagues often used his surname as a unit which was measured in one word per hour. Physicists such as Homie J. Bhaba and Fred Hoyle were his students. During the last years of his life, Dirac worked as a professor at ‘Florida State University.’ We have curated some of Paul Dirac quotes on science, data, God, beauty, progress, life, inspirational, writing, men, poetry, religion, atheism, etc.

It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress.

Paul Dirac

It is more important to have beauty in one's equations than to have them fit experiment.

Paul Dirac

In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in poetry, it is the exact opposite.

Paul Dirac

If we are honest - and scientists have to be - we must admit that religion is a jumble of false assertions, with no basis in reality.

Paul Dirac

If there is a God, he's a great mathematician.

Paul Dirac

I think it is the general rule that the originator of a new idea is not the most suitable person to develop it, because his fears of something going wrong are really too strong... At age 69.

Paul Dirac

I do not see how a man can work on the frontiers of physics and write poetry at the same time. They are in opposition.

Paul Dirac

I consider that I understand an equation when I can predict the properties of its solutions, without actually solving it.

Paul Dirac

I admired Bohr very much. We had long talks together, long talks in which Bohr did practically all the talking.

Paul Dirac

Hopes are always accompanied by fears, and, in scientific research, the fears are liable to become dominant.

Paul Dirac

God used beautiful mathematics in creating the world.

Paul Dirac

As time goes on, it becomes increasingly evident that the rules which the mathematician finds interesting are the same as those which Nature has chosen.

Paul Dirac

A theory with mathematical beauty is more likely to be correct than an ugly one that fits some experimental data.

Paul Dirac

A physical law must possess mathematical beauty.

Paul Dirac

A great deal of my work is just playing with equations and seeing what they give.

Paul Dirac

A book on the new physics, if not purely descriptive of experimental work, must essentially be mathematical.

Paul Dirac

A good deal of my research in physics has consisted in not setting out to solve some particular problem, but simply examining mathematical equations of a kind that physicists use and trying to fit them together in an interesting way, regardless of any application that the work may have. It is simply a search for pretty mathematics. It may turn out later to have an application. Then one has good luck. At age 78.

Paul Dirac

A termination of one's life is necessary in the scheme of things to provide a logical reason for unselfishness. . . . The fact that there is an end to one's life compels one to take an interest in things that will continue to live after one is dead.

Paul Dirac

I found the best ideas usually came, not when one was actively striving for them, but when one was in a more relaxed state… I used to take long solitary walks on Sundays, during which I tended to review the current situation in a leisurely way. Such occasions often proved fruitful, even though (or perhaps, because) the primary purpose of the walk was relaxation and not research.

Paul Dirac

I learnt to distrust all physical concepts as the basis for a theory. Instead one should put one's trust in a mathematical scheme, even if the scheme does not appear at first sight to be connected with physics. One should concentrate on getting interesting mathematics.

Paul Dirac

I should like to suggest to you that the cause of all the economic troubles is that we have an economic system which tries to maintain an equality of value between two things, which it would be better to recognise from the beginning as of unequal value.

Paul Dirac

If you are receptive and humble, mathematics will lead you by the hand. Again and again, when I have been at a loss how to proceed, I have just had to wait until I have felt the mathematics led me by the hand. It has led me along an unexpected path, a path where new vistas open up, a path leading to new territory, where one can set up a base of operations, from which one can survey the surroundings and plan future progress.

Paul Dirac

It is more important to have beauty in one's equations than to have them fit experiment... It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress. If there is not complete agreement between the results of one's work and experiment, one should not allow oneself to be too discouraged, because the discrepancy may well be due to minor features that are not properly taken into account and that will get cleared up with further developments of the theory.

Paul Dirac

It is quite clear that beauty does depend on one's culture and upbringing for certain kinds of beauty, pictures, literature, poetry and so on...But mathematical beauty is of a rather different kind. I should say perhaps it is of a completely different kind and transcends these personal factors. It is the same in all countries and at all periods of time.

Paul Dirac

It was not until some weeks later that I realized there is no need to restrict oneself to 2 by 2 matrices. One could go on to 4 by 4 matrices, and the problem is then easily soluable. In retrospect, it seems strange that one can be so much held up over such an elementary point. The resulting wave equation for the electron turned out to be very successful. It led to correct values for the spin and the magnetic moment. This was quite unexpected. The work all followed from a study of pretty mathematics, without any thought being given to these physical properties of the electron.
