Everything Is Made Of Atoms.

That Is The Logical Tight-rope On Which We Have To Walk If We Wish To Interpret Nature.

Thus We Can Get The Correct Answer For The Probability Of Partial Reflection By Imagining (falsely) That All Reflection Comes From Only The Front And Back Surfaces. In This Intuitively Easy Analysis, The 'front Surface' And 'back Surface' Arrows Are Mathematical Constructions That Give Us The Right Answer, Whereas .... A More Accurate Representation Of What Is Really Going On: Partial Reflection Is The Scattering Of Light By Electrons Inside The Glass.

The Quantum Universe Has A Quotation From Me In Every Chapter - But It's A Damn Good Book Anyway.

It Is The Facts That Matter, Not The Proofs. Physics Can Progress Without The Proofs, But We Can't Go On Without The Facts ... If The Facts Are Right, Then The Proofs Are A Matter Of Playing Around With The Algebra Correctly.

I Believe That A Scientist Looking At Nonscientific Problems Is Just As Dumb As The Next Guy.
