God Used Beautiful Mathematics In

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.

If There Is A God, He's A Great Mathematician.

It Is More Important To Have Beauty In One's Equations Than To Have Them Fit Experiment... It Seems That If One Is Working From The Point Of View Of Getting Beauty In One's Equations, And If One Has Really A Sound Insight, One Is On A Sure Line Of Progress. If There Is Not Complete Agreement Between The Results Of One's Work And Experiment, One Should Not Allow Oneself To Be Too Discouraged, Because The Discrepancy May Well Be Due To Minor Features That Are Not Properly Taken Into Account And That Will Get Cleared Up With Further Developments Of The Theory.

Well, In The First Place, It Leads To Great Anxiety As To Whether It's Going To Be Correct Or Not ... I Expect That's The Dominating Feeling. It Gets To Be Rather A Fever... At Age 60, When Asked About His Feelings On Discovering The Dirac Equation.
