# paul dirac Quotes

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

— Paul Dirac

The research worker, in his efforts to express the fundamental laws of Nature in mathematical form, should strive mainly for mathematical beauty. He should take simplicity into consideration in a subordinate way to beauty ... It often happens that the requirements of simplicity and beauty are the same, but where they clash, the latter must take precedence.

— 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

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

Mathematics is the tool specially suited for dealing with abstract concepts of any kind and there is no limit to its power in this field.

— Paul Dirac

What makes the theory of relativity so acceptable to physicists in spite of its going against the principle of simplicity is its great mathematical beauty. This is a quality which cannot be defined, any more than beauty in art can be defined, but which people who study mathematics usually have no difficulty in appreciating.

— Paul Dirac

When [Erwin SchrÃ¶dinger] went to the Solvay conferences in Brussels, he would walk from the station to the hotel where the delegates stayed, carrying all his luggage in a rucksack and looking so like a tramp that it needed a great deal of argument at the reception desk before he could claim a room.

— Paul Dirac

Scientific progress is measured in units of courage, not intelligence.

— Paul Dirac

The measure of greatness in a scientific idea is the extent to which it stimulates thought and opens up new lines of research.

— Paul Dirac

One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe.

— Paul Dirac

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

— Paul Dirac

A physical law must possess mathematical beauty.

— Paul Dirac

The fundamental laws necessary for the mathematical treatment of a large part of physics and the whole of chemistry are thus completely known, and the difficulty lies only in the fact that application of these laws leads to equations that are too complex to be solved.

— Paul Dirac

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

— 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

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

Living is worthwhile if one can contribute in some small way to this endless chain of progress.

— Paul Dirac

Pick a flower on Earth and you move the farthest star.

— Paul Dirac

God used beautiful mathematics in creating the world.

— Paul Dirac

The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way. The two are incompatible.

— Paul Dirac

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

— Paul Dirac

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

— Paul Dirac

No. I had successfully solved the difficulty of finding a description of the electron which was consistent with both relativity and quantum mechanics. Of course, when you solve one difficulty, other new difficulties arise. You then try to sove them. You can never solve all difficulties at once.

— Paul Dirac

The shortage of buyers, which the world is suffering from, is readily understood, not as due to people not wishing to obtain possession of goods, but as people being unwilling to part with something which might earn a regular income in exchange for those goods.

— 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

Quantum mechanics has explained all of chemistry and most of physics.

— Paul Dirac

Theoretical physicists accept the need for mathematical beauty as an act of faith... For example, the main reason why the theory of relativity is so universally accepted is its mathematical beauty.

— Paul Dirac

There is in my opinion a great similarity between the problems provided by the mysterious behavior of the atom and those provided by the present economic paradoxes confronting the world.

— Paul Dirac

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

— 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

Well, in the first place, it leads to great anxiety as to whether it's going to be correct or not ... I expect that's the dominating feeling. It gets to be rather a fever... At age 60, when asked about his feelings on discovering the Dirac equation.

— 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

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

— 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

The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.

— Paul Dirac

Renormalization is just a stop-gap procedure. There must be some fundamental change in our ideas, probably a change just as fundamental as the passage from Bohr's orbit theory to quantum mechanics. When you get a number turning out to be infinite which ought to be finite, you should admit that there is something wrong with your equations, and not hope that you can get a good theory just by doctoring up that number.

— Paul Dirac

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

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

The only object of theoretical physics is to calculate results that can be compared with experiment... it is quite unnecessary that any satisfactory description of the whole course of the phenomena should be given.

— Paul Dirac

I think it is a peculiarity of myself that I like to play about with equations, just looking for beautiful mathematical relations which maybe don't have any physical meaning at all. Sometimes they do.At age 60.

— Paul Dirac
