If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

Fudging the data in any way whatsoever is quite literally a sin against the holy ghost of science. 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.

What I like about sceptics is that in good science you need critics that make you think: 'Crumbs, have I made a mistake here?' If you don't have that continuously, you really are up the creek. The good sceptics have done a good service, but some of the mad ones I think have not done anyone any favours.

Faulkner is a writer who has had much to do with my soul, but Hemingway is the one who had the most to do with my craft - not simply for his books, but for his astounding knowledge of the aspect of craftsmanship in the science of writing.

Science fiction films are not about science. They are about disaster, which is one of the oldest subjects of art.
