When we look out into space, we're looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It's an amazing thing. The history is there for us to see. It's not mushed up like the geologic record of Earth. You can just see it exactly as it was.

When I won the MacArthur, I didn't receive a different amount of money than the men did.

A family living at the poverty level is unlikely to be able to afford a computer at home. Even with a computer, access to the Internet is another significant expense. A child might borrow a book from a public library; but it is not possible to take a computer home.
