God Used Beautiful Mathematics In Creating The

Hopes Are Always Accompanied By Fears, And, In Scientific Research, The Fears Are Liable To Become Dominant.

The Measure Of Greatness In A Scientific Idea Is The Extent To Which It Stimulates Thought And Opens Up New Lines Of Research.

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.

The Only Object Of Theoretical Physics Is To Calculate Results That Can Be Compared With Experiment... It Is Quite Unnecessary That Any Satisfactory Description Of The Whole Course Of The Phenomena Should Be Given.

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.
