I Do Not See How

Well, In The First Place, It Leads To Great Anxiety As To Whether It's Going To Be Correct Or Not ... I Expect That's The Dominating Feeling. It Gets To Be Rather A Fever... At Age 60, When Asked About His Feelings On Discovering The Dirac Equation.

A Good Deal Of My Research In Physics Has Consisted In Not Setting Out To Solve Some Particular Problem, But Simply Examining Mathematical Equations Of A Kind That Physicists Use And Trying To Fit Them Together In An Interesting Way, Regardless Of Any Application That The Work May Have. It Is Simply A Search For Pretty Mathematics. It May Turn Out Later To Have An Application. Then One Has Good Luck. At Age 78.

What Makes The Theory Of Relativity So Acceptable To Physicists In Spite Of Its Going Against The Principle Of Simplicity Is Its Great Mathematical Beauty. This Is A Quality Which Cannot Be Defined, Any More Than Beauty In Art Can Be Defined, But Which People Who Study Mathematics Usually Have No Difficulty In Appreciating.

If There Is A God, He's A Great Mathematician.

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.
