Hopes Are Always Accompanied By Fears, And,

If You Are Receptive And Humble, Mathematics Will Lead You By The Hand. Again And Again, When I Have Been At A Loss How To Proceed, I Have Just Had To Wait Until I Have Felt The Mathematics Led Me By The Hand. It Has Led Me Along An Unexpected Path, A Path Where New Vistas Open Up, A Path Leading To New Territory, Where One Can Set Up A Base Of Operations, From Which One Can Survey The Surroundings And Plan Future Progress.

Living Is Worthwhile If One Can Contribute In Some Small Way To This Endless Chain Of Progress.

Quantum Mechanics Has Explained All Of Chemistry And Most Of Physics.

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

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.
