I Admired Bohr Very Much. We Had

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.

It Was Not Until Some Weeks Later That I Realized There Is No Need To Restrict Oneself To 2 By 2 Matrices. One Could Go On To 4 By 4 Matrices, And The Problem Is Then Easily Soluable. In Retrospect, It Seems Strange That One Can Be So Much Held Up Over Such An Elementary Point. The Resulting Wave Equation For The Electron Turned Out To Be Very Successful. It Led To Correct Values For The Spin And The Magnetic Moment. This Was Quite Unexpected. The Work All Followed From A Study Of Pretty Mathematics, Without Any Thought Being Given To These Physical Properties Of The Electron.

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.

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.

One Could Perhaps Describe The Situation By Saying That God Is A Mathematician Of A Very High Order, And He Used Very Advanced Mathematics In Constructing The Universe.
