The World Is Just -

A Model Is Done When Nothing Else Can Be Taken Out.

You Have This World Of Mathematics, Which Is Very Real And Which Contains All Kinds Of Wonderful Stuff. And Then We Also Have The World Of Nature, Which Is Real, Too.

I Think It's Much Better To Have Your Eyes Open, But On The Other Hand, Of Course It Can Do Harm If You Tell People Look, There's All These Terrible Things You Can Do And Then Some Idiot May Go Ahead And Do It.

I Think The Biggest Misconception About Mathematics Is That Everybody Has To Learn It. That Seems To Be A Complete Mistake. All The Time Worrying About Pushing The Children And Getting Them To Be Mathematically Literate And All That Stuff. It's Terribly Hard On The Kids. It's Also Hard On The Teachers. And I Think It's Totally Useless. To Me, Mathematics Is Like Playing The Violin. Some People Can Do It - Others Can't. If You Don't Have It, Then There's No Point In Pretending.

Progress In Science Is Often Built On Wrong Theories That Are Later Corrected. It Is Better To Be Wrong Than To Be Vague.
