Think How Hard Physics Would Be If

Of Course The Word Chaos Is Used In Rather A Vague Sense By A Lot Of Writers, But In Physics It Means A Particular Phenomenon, Namely That In A Nonlinear System The Outcome Is Often Indefinitely, Arbitrarily Sensitive To Tiny Changes In The Initial Condition

Modern Language Must Be Older Than The Cave Paintings And Cave Engravings And Cave Sculptures And Dance Steps In The Soft Clay In The Caves In Western Europe, In The Aurignacian Period Some 35,000 Years Ago, Or Earlier. I Can't Believe They Did All Those Things And Didn't Also Have A Modern Language.

All Of Modern Physics Is Governed By That Magnificent And Thoroughly Confusing Discipline Called Quantum Mechanics ... It Has Survived All Tests And There Is No Reason To Believe That There Is Any Flaw In It. We All Know How To Use It And How To Apply It To Problems; And So We Have Learned To Live With The Fact That Nobody Can Understand It.

In Fact Any Experiment That Measures A Quantum Effect Is One In Which The Quantum Effect Is Aligned With The Behavior Of Some Heavy, Macroscopic Object; That's How We Measure It

What Is Especially Striking And Remarkable Is That In Fundamental Physics A Beautiful Or Elegant Theory Is More Likely To Be Right Than A Theory That Is Inelegant.
