Physicists Like To Think That All You

If You Can't Explain Something To A First Year Student, Then You Haven't Really Understood .

So My Antagonist Said, "is It Impossible That There Are Flying Saucers? Can You Prove That It's Impossible?" "no," I Said, "i Can't Prove It's Impossible. It's Just Very Unlikely." At That He Said, "you Are Very Unscientific. If You Can't Prove It Impossible Then How Can You Say That It's Unlikely?" But That Is The Way That Is Scientific. It Is Scientific Only To Say What Is More Likely And What Less Likely, And Not To Be Proving All The Time The Possible And Impossible.

We Need To Teach How Doubt Is Not To Be Feared But Welcomed. It's Ok To Say, "i Don't Know."

If An Apple Was Magnified To The Size Of The Earth, Then The Atoms In The Apple Would Be Approximately The Size Of The Original Apple.

Therefore Psychologically We Must Keep All The Theories In Our Heads, And Every Theoretical Physicist Who Is Any Good Knows Six Or Seven Different Theoretical Representations For Exactly The Same Physics.
