I Admired Bohr Very Much. We Had

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.

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.

I Think It Is A Peculiarity Of Myself That I Like To Play About With Equations, Just Looking For Beautiful Mathematical Relations Which Maybe Don't Have Any Physical Meaning At All. Sometimes They Do. At Age 60.

The Only Object Of Theoretical Physics Is To Calculate Results That Can Be Compared With Experiment... It Is Quite Unnecessary That Any Satisfactory Description Of The Whole Course Of The Phenomena Should Be Given.

I Learnt To Distrust All Physical Concepts As The Basis For A Theory. Instead One Should Put One's Trust In A Mathematical Scheme, Even If The Scheme Does Not Appear At First Sight To Be Connected With Physics. One Should Concentrate On Getting Interesting Mathematics.
