NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

I'm not religious, but I put it that way because I feel so strongly. It's the one thing you do not ever do. You've got to have standards.

The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that, but it's got all the sort of terms that religions use. The greens use guilt. That just shows how religious greens are. You can't win people round by saying they are guilty for putting (carbon dioxide) in the air.

We live at a time when emotions and feelings count more than truth, and there is a vast ignorance of science

Composing computer programs to solve scientific problems is like writing poetry. You must choose every word with care and link it with the other words in perfect syntax. There is no place for verbosity or carelessness. To become fluent in a computer lnaguage demands almost the antithesis of modern loose thinking. It requires many interactive sessions, the hands-on use of the device. You do not learn a foreign language from a book, rather you have to live in the country for year to let the langauge become an automatic part of you, and the same is true for computer languages.

Just after World War II, this country led the world in science by every way you could measure it, yet the number of scientists was a tiny proportion of what it is now.
