Well, In The First Place, It Leads

The Research Worker, In His Efforts To Express The Fundamental Laws Of Nature In Mathematical Form, Should Strive Mainly For Mathematical Beauty. He Should Take Simplicity Into Consideration In A Subordinate Way To Beauty ... It Often Happens That The Requirements Of Simplicity And Beauty Are The Same, But Where They Clash, The Latter Must Take Precedence.

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.

As Time Goes On, It Becomes Increasingly Evident That The Rules Which The Mathematician Finds Interesting Are The Same As Those Which Nature Has Chosen.

Theoretical Physicists Accept The Need For Mathematical Beauty As An Act Of Faith... For Example, The Main Reason Why The Theory Of Relativity Is So Universally Accepted Is Its Mathematical Beauty.
