A Book On The New Physics, If

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.

It Is More Important To Have Beauty In One's Equations Than To Have Them Fit Experiment.

The Methods Of Theoretical Physics Should Be Applicable To All Those Branches Of Thought In Which The Essential Features Are Expressible With Numbers.

Hopes Are Always Accompanied By Fears, And, In Scientific Research, The Fears Are Liable To Become Dominant.

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.
