If There Is A God, He's A

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.

Just By Studying Mathematics We Can Hope To Make A Guess At The Kind Of Mathematics That Will Come Into The Physics Of The Future... If Someone Can Hit On The Right Lines Along Which To Make This Development, It May Lead To A Future Advance In Which People Will First Discover The Equations And Then, After Examining Them, Gradually Learn How To Apply Them... My Own Belief Is That This Is A More Likely Line Of Progress Than Trying To Guess At Physical Pictures.

It Is Quite Clear That Beauty Does Depend On One's Culture And Upbringing For Certain Kinds Of Beauty, Pictures, Literature, Poetry And So On...but Mathematical Beauty Is Of A Rather Different Kind. I Should Say Perhaps It Is Of A Completely Different Kind And Transcends These Personal Factors. It Is The Same In All Countries And At All Periods Of Time.

I Admired Bohr Very Much. We Had Long Talks Together, Long Talks In Which Bohr Did Practically All The Talking.

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.
