Living Is Worthwhile If One Can Contribute

A Physical Law Must Possess Mathematical Beauty.

The Methods Of Theoretical Physics Should Be Applicable To All Those Branches Of Thought In Which The Essential Features Are Expressible With Numbers.

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.

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.

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.
