A Physical Law Must Possess Mathematical Beauty.

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.

A Theory With Mathematical Beauty Is More Likely To Be Correct Than An Ugly One That Fits Some Experimental Data.

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.

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.

Quantum Mechanics Has Explained All Of Chemistry And Most Of Physics.
