When you are famous it is hard to work on small problems. This is what did Shannon in. After information theory, what do you do for an encore? The great scientists often make this error. They fail to continue to plant the little acorns from which the mighty oak trees grow. They try to get the big thing right off. And that isn't the way things go. So that is another reason why you find that when you get early recognition it seems to sterilize you. In fact I will give you my favorite quotation of many years. The Institute for Advanced Study in Princeton, in my opinion, has ruined more good scientists than any institution has created, judged by what they did before they came and judged by what they did after.

The next generation of telescopes will see millions of events per night with computers that sift through huge amounts of data. If we had had access to a computer, we would never have programmed it to look for something so unexpected. How do you pick up the things you don't know exist, the things you can't tell it to look for? My project was to study quasars, and then we accidentally stumble over these things called pulsars. They were totally unexpected, totally unknown – and it's been huge fun.

To me poor people are like bonsai trees. When you plant the best seed of the tallest tree in a flower-pot, you get a replica of the tallest tree, only inches tall. There is nothing wrong with the seed you planted, only the soil-base that is too inadequate. Poor people are bonsai people. There is nothing wrong in their seeds. Simply, society never gave them the base to grow on.

Now, this ideology gets policed by this one very dangerous question, which is, "What percentage of my donation goes to the cause versus overhead?" There are a lot of problems with this question. I'm going to just focus on two. First, it makes us think that overhead is a negative, that it is somehow not part of the cause. But it absolutely is, especially if it's being used for growth.

Whenever you’re making a movie, especially when you’re writing, you always have self-doubts. I did the first location shooting in Tunisia.

I liked all the normal kinds of adventure books, Kidnapped, Treasure Island, Huck Finn sorts of things. I loved Swiss Family Robinson and that whole period of South Sea adventure movies. I liked westerns. Westerns were very big when I was growing up. When we finally got a television there was a whole run of westerns on television. John Wayne films, directed by John Ford, before I knew who John Ford was. I think those were very influential in my enjoyment of movies.
