The Fundamental Laws Necessary For The Mathematical

Living Is Worthwhile If One Can Contribute In Some Small Way To This Endless Chain Of Progress.

A Great Deal Of My Work Is Just Playing With Equations And Seeing What They Give.

Renormalization Is Just A Stop-gap Procedure. There Must Be Some Fundamental Change In Our Ideas, Probably A Change Just As Fundamental As The Passage From Bohr's Orbit Theory To Quantum Mechanics. When You Get A Number Turning Out To Be Infinite Which Ought To Be Finite, You Should Admit That There Is Something Wrong With Your Equations, And Not Hope That You Can Get A Good Theory Just By Doctoring Up That Number.

A Book On The New Physics, If Not Purely Descriptive Of Experimental Work, Must Essentially Be Mathematical.

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.
