I Do Not See How

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.

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 Have Any Physical Meaning At All. Sometimes They Do. At Age 60.

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

Scientific Progress Is Measured In Units Of Courage, Not Intelligence.
