If You Can't Explain Something To A

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.

In Fact, The Science Of Thermodynamics Began With An Analysis, By The Great Engineer Sadi Carnot, Of The Problem Of How To Build The Best And Most Efficient Engine, And This Constitutes One Of The Few Famous Cases In Which Engineering Has Contributed To Fundamental Physical Theory. Another Example That Comes To Mind Is The More Recent Analysis Of Information Theory By Claude Shannon. These Two Analyses, Incidentally, Turn Out To Be Closely Related.

There Is No Learning Without Having To Pose A Question. And A Question Requires Doubt.

It Is Going To Be Necessary That Everything That Happens In A Finite Volume Of Space And Time Would Have To Be Analyzable With A Finite Number Of Logical Operations. The Present Theory Of Physics Is Not That Way, Apparently. It Allows Space To Go Down Into Infinitesimal Distances, Wavelengths To Get Infinitely Great, Terms To Be Summed In Infinite Order, And So Forth; And Therefore, If This Proposition [that Physics Is Computer-simulatable] Is Right, Physical Law Is Wrong.

Nobody Ever Figures Out What Life Is All About, And It Doesn't Matter. Explore The World. Nearly Everything Is Really Interesting If You Go Into It Deeply Enough.
