I Admired Bohr Very Much. We Had

A Physical Law Must Possess Mathematical Beauty.

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.

A Termination Of One's Life Is Necessary In The Scheme Of Things To Provide A Logical Reason For Unselfishness. . . . The Fact That There Is An End To One's Life Compels One To Take An Interest In Things That Will Continue To Live After One Is Dead.

A Theory With Mathematical Beauty Is More Likely To Be Correct Than An Ugly One That Fits Some Experimental Data.

Mathematics Is The Tool Specially Suited For Dealing With Abstract Concepts Of Any Kind And There Is No Limit To Its Power In This Field.
