Text Quotes
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 Quotes)
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’s the exact opposite. (Paul Dirac Quotes)
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 Quotes)
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 Quotes)
God used beautiful mathematics in creating the world (Paul Dirac Quotes)
There are always more people who prefer to speak than to listen (Paul Dirac Quotes)
I consider that I understand an equation when I can predict the properties of its solutions, without actually solving it (Paul Dirac Quotes)
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 (Paul Dirac Quotes)
A book on the new physics, if not purely descriptive of experimental work, must essentially be mathematical (Paul Dirac Quotes)
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 Quotes)
A theory with mathematical beauty is more likely to be correct than an ugly one that fits some experimental data (Paul Dirac Quotes)
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 Quotes)
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 Quotes)
It is more important to have beauty in one’s equations than to have them fit experiment (Paul Dirac Quotes)
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation (Paul Dirac Quotes)
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 Quotes)
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 Quotes)
Living is worthwhile if one can contribute in some small way to this endless chain of progress (Paul Dirac Quotes)
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 Quotes)
A great deal of my work is just playing with equations and seeing what they give (Paul Dirac Quotes)
Just by studying mathematics we can hope to make a guess at the kind of mathematics that will come into the physics of the future... If someone can hit on the right lines along which to make this development, it m may lead to a future advance in which people will first discover the equations and then, after examining them, gradually learn how to apply the... My own belief is that this is a more likely line of progress than trying to guess at physical pictures (Paul Dirac Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
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 Quotes)
