If We Want To Go To Space

We Simply Don't Know Yet What's Going To Happen To The Carbon In The Atmosphere.

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.

When World War Ii Came Along, Which Was When I Was A Teenager, We All Expected We Would Have Anthrax Bombs And This Kind Of Stuff. We Thought It Would Be A Biological War. Fortunately It Wasn't And, But It's Because The Danger Is Still There And By Some Miracle We Escaped All That, So You Never Can Tell What It Going To Happen, But Biology Certainly Could Be Even Worse Than Physics And Chemistry.

The Progress Of Science Requires The Growth Of Understanding In Both Directions, Downward From The Whole To The Parts And Upward From The Parts To The Whole. A Reductionist Philosophy, Arbitrarily Proclaiming That The Growth Of Understanding Must Go Only In One Direction, Makes No Scientific Sense. Indeed, Dogmatic Philosophical Beliefs Of Any Kind Have No Place In Science.

Mathematics Is Really An Art, Not A Science. You Could Say Science Also Is An Art. So I Would Say The Difference Is Something You Can't Really Describe - You Can Only Recognize. You Hear Somebody Playing The Violin, And It Was Fritz Kreisler Or It Was Somebody Else, And You Can Tell The Difference. It Is So In Almost Every Art. We Just Don't Understand Why It Is That There Are Just A Few People Who Are Just Completely Off The Scale And The Rest Of Them Are Just Mediocre. And We Don't Know Why. But I Say It's Certainly True Of Mathematics.
