If You Are Receptive And Humble, Mathematics

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

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.

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.

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.

It Is More Important To Have Beauty In One's Equations Than To Have Them Fit Experiment.
