There Is In My Opinion A Great

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.

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.

The Underlying Physical Laws Necessary For The Mathematical Theory Of A Large Part Of Physics And The Whole Of Chemistry Are Thus Completely Known, And The Difficulty Is Only That The Exact Application Of These Laws Leads To Equations Much Too Complicated To Be Soluble. It Therefore Becomes Desirable That Approximate Practical Methods Of Applying Quantum Mechanics Should Be Developed, Which Can Lead To An Explanation Of The Main Features Of Complex Atomic Systems Without Too Much Computation.

I Do Not See How A Man Can Work On The Frontiers Of Physics And Write Poetry At The Same Time. They Are In Opposition. In Science You Want To Say Something That Nobody Knew Before, In Words Which Everyone Can Understand. In Poetry You Are Bound To Say ... Something That Everyone Knows Already In Words That Nobody Can Understand. Commenting To Him About The Poetry J. Robert Oppenheimer Wrote.

I Should Like To Suggest To You That The Cause Of All The Economic Troubles Is That We Have An Economic System Which Tries To Maintain An Equality Of Value Between Two Things, Which It Would Be Better To Recognise From The Beginning As Of Unequal Value.
