It Is A Primitive Form Of Thought

Do Not Put Too Much Confidence In Experimental Results Until They Have Been Confirmed By Theory.

The Universe Will Finally Become A Ball Of Radiation, Becoming More And More Rarified And Passing Into Longer And Longer Wave-lengths. The Longest Waves Of Radiation Are Hertzian Waves Of The Kind Used In Broadcasting. About Every 1500 Million Years This Ball Of Radio Waves Will Double In Diameter; And It Will Go On Expanding In Geometrical Progression For Ever. Perhaps Then I May Describe The End Of The Physical World As-one Stupendous Broadcast.

Who Will Observe The Observers?

If Someone Points Out To You That Your Pet Theory Of The Universe Is In Disagreement With Maxwell's Equations - Then So Much The Worse For Maxwell's Equations. If It Is Found To Be Contradicted By Observation - Well, These Experimentalists Do Bungle Things Sometimes. But If Your Theory Is Found To Be Against The Second Law Of Thermodynamics I Can Give You No Hope; There Is Nothing For It But To Collapse In Deepest Humiliation.

Never Accept A Fact Until It Has Been Verified By Theory.
