Renormalization is just a stop-gap procedure. There must be some fundamental change in our ideas, probably a change just as fundamental as the passag….

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 h….

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

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 ….

A good deal of my research in physics has consisted in not setting out to solve some particular problem, but simply examining mathematical equations ….

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

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 t….

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

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 ….

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 constru….

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 h….

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 ….

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

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….

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 th….

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 ….

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

The physicist, in his study of natural phenomena, has two methods of making progress: (1) the method of experiment and observation, and (2) the metho….

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 wa….

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

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