Work As Hard And As Much As

Physics Is Like Sex: Sure, It May Give Some Practical Results, But That's Not Why We Do It.

I Have The Advantage Of Having Found Out How Hard It Is To Get To Really Know Something. How Careful You Have To Be About Checking Your Experiments. How Easy It Is To Make Mistakes And Fool Yourself. I Know What It Means To Know Something.

It Does Not Make Any Difference How Beautiful Your Guess Is. It Does Not Make Any Difference How Smart You Are, Who Made The Guess, Or What His Name Is If It Disagrees With Experiment It Is Wrong. That Is All There Is To It.

If We Will Only Allow That, As We Progress, We Remain Unsure, We Will Leave Opportunities For Alternatives.

The Exception Tests The Rule.
