A Theory Can Be Proved By Experiment;

To Have Security Against Atomic Bombs And Against The Other Biological Weapons, We Have To Prevent War, For If We Cannot Prevent War Every Nation Will Use Every Means That Is At Their Disposal; And In Spite Of All Promises They Make, They Will Do It. At The Same Time, So Long As War Is Not Prevented, All The Governments Of The Nations Have To Prepare For War, And If You Have To Prepare For War, Then You Are In A State Where You Cannot Abolish War.

No One But A Theorist Believes His Theory; Everyone Puts Faith In A Laboratory Result But The Experimenter Himself.

Truth Is What Stands The Test Of Experience.

Belief In An External World Independent Of The Perceiving Subject Is The Basis Of All Natural Science.

I Wouldn't Want To Live If I Did Not Have My Work. In Any Case, It's Good That I'm Already Old And Personally Don't Have To Count On A Prolonged Future.
