A Great Deal Of My Work Is

A Physical Law Must Possess Mathematical Beauty.

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 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.

I Found The Best Ideas Usually Came, Not When One Was Actively Striving For Them, But When One Was In A More Relaxed State… I Used To Take Long Solitary Walks On Sundays, During Which I Tended To Review The Current Situation In A Leisurely Way. Such Occasions Often Proved Fruitful, Even Though (or Perhaps, Because) The Primary Purpose Of The Walk Was Relaxation And Not Research.

The Fundamental Laws Necessary For The Mathematical Treatment Of A Large Part Of Physics And The Whole Of Chemistry Are Thus Completely Known, And The Difficulty Lies Only In The Fact That Application Of These Laws Leads To Equations That Are Too Complex To Be Solved.
