This Is A Question Too Difficult For

My Mind Is My Laboratory.

However We Select From Nature A Complex [of Phenomena] Using The Criterion Of Simplicity, In No Case Will Its Theoretical Treatment Turn Out To Be Forever Appropriate (sufficient).... I Do Not Doubt That The Day Will Come When [general Relativity], Too, Will Have To Yield To Another One, For Reasons Which At Present We Do Not Yet Surmise. I Believe That This Process Of Deepening Theory Has No Limits.

I Cannot Conceive Of A God Who Rewards And Punishes His Creatures, Or Has A Will Of The Type Of Which We Are Conscious In Ourselves. An Individual Who Should Survive His Physical Death Is Also Beyond My Comprehension, Nor Do I Wish It Otherwise; Such Notions Are For The Fears Or Absurd Egoism Of Feeble Souls.

Whatever Your Problems In Math Are, I Assure Mine Are Greater.

The Physicist's Greatest Tool Is His Wastebasket.
