The Russians did much bigger space launch vehicles for launching satellites and for getting men in orbit. They did that much sooner than America because America was very good at something else.

A NASA astronaut and a Russian cosmonaut can't be creative. He has to follow a predetermined detailed checklist written by an engineer and if he gets a little creative he'll never fly again.

We didn't know the importance of home computers before the Internet. We had them mostly for fun, then the Internet came along and was enabled by all the PCs out there.

Science is not about consensus, and consensus is not science.

America was good enough to make a small compact lighter weight nuclear weapon. The Russians still had these big clunky heavy ones, so they had to build the big boosters in the arm's war, so now all of the sudden Russia could take off the shelf and put into orbit much heavier things than we could, so that's why they had the original leadership.

Flight out of the atmosphere is a simple thing to do and should have been available to the public twenty years ago. Ten years from now, we will have space tourism where you will be able to see the black sky and the curvature of the earth. It will be the most exciting roller coaster ride you can buy.

I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have a tipping point for atmospheric carbon dioxide, it's just nonsense.
