I Think That The Discovery Of Antimatter

An Expert Is Someone Who Knows Some Of The Worst Mistakes That Can Be Made In His Subject And How To Avoid Them.

It Was About Three O'clock At Night When The Final Result Of The Calculation [which Gave Birth To Quantum Mechanics] Lay Before Me ... At First I Was Deeply Shaken ... I Was So Excited That I Could Not Think Of Sleep. So I Left The House ... And Awaited The Sunrise On Top Of A Rock.

"uncertainty" Is Not "i Don't Know." It Is "i Can't Know." "i Am Uncertain" Does Not Mean "i Could Be Certain."

The Incomplete Knowledge Of A System Must Be An Essential Part Of Every Formulation In Quantum Theory. Quantum Theoretical Laws Must Be Of A Statistical Kind. To Give An Example: We Know That The Radium Atom Emits Alpha-radiation. Quantum Theory Can Give Us An Indication Of The Probability That The Alpha-particle Will Leave The Nucleus In Unit Time, But It Cannot Predict At What Precise Point In Time The Emission Will Occur, For This Is Uncertain In Principle.

Every Word Or Concept, Clear As It May Seem To Be, Has Only A Limited Range Of Applicability.
