57 Quotes by 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.

It is more important to have beauty in one’s equation than to have them fit experiment

A physical law must possess mathematical beauty

The underlying physical laws necessary for the mathematical theory of a larger part of physics and the whole of chemistry are thus completely known.

It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted.

God used beautiful mathematics in creating the world.

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.

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.

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.
