The most watched programme on the BBC, after the news, is probably 'Doctor Who.' What has happened is that science fiction has been subsumed into modern literature. There are grandparents out there who speak Klingon, who are quite capable of holding down a job. No one would think twice now about a parallel universe.

Physics does not change the nature of the world it studies, and no science of behavior can change the essential nature of man, even though both sciences yield technologies with a vast power to manipulate the subject matters.

Science is a differential equation. Religion is a boundary condition.

Science is all metaphor.

I like science and I love gym. Oh, and I like art, but I'm really bad at it. I'm just a terrible drawer. I can't draw a circle. Even with a ruler, I can't draw a straight line.

Both the man of science and the man of action live always at the edge of mystery, surrounded by it.

Some day science may have the existence of mankind in power, and the human race can commit suicide by blowing up the world.

Politicians should read science fiction, not westerns and detective stories.

Freedom is absolutely necessary for the progress in science and the liberal arts.

All good criticism should be judged the way art is. You shouldn't read it the way you read history or science.
