A Book On The New Physics, If

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

The Underlying Physical Laws Necessary For The Mathematical Theory Of A Large Part Of Physics And The Whole Of Chemistry Are Thus Completely Known, And The Difficulty Is Only That The Exact Application Of These Laws Leads To Equations Much Too Complicated To Be Soluble. It Therefore Becomes Desirable That Approximate Practical Methods Of Applying Quantum Mechanics Should Be Developed, Which Can Lead To An Explanation Of The Main Features Of Complex Atomic Systems Without Too Much Computation.

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.

Mathematics Is The Tool Specially Suited For Dealing With Abstract Concepts Of Any Kind And There Is No Limit To Its Power In This Field.

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.
