If We Are Honest -

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

The Physicist, In His Study Of Natural Phenomena, Has Two Methods Of Making Progress: (1) The Method Of Experiment And Observation, And (2) The Method Of Mathematical Reasoning. The Former Is Just The Collection Of Selected Data; The Latter Enables One To Infer Results About Experiments That Have Not Been Performed. There Is No Logical Reason Why The Second Method Should Be Possible At All, But One Has Found In Practice That It Does Work And Meets With Reasonable Success.

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.

In Science One Tries To Tell People, In Such A Way As To Be Understood By Everyone, Something That No One Ever Knew Before. But In Poetry, It Is The Exact Opposite.

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.
