Imagine if we had stopped science in 1904. Yes, there would have been no nerve gas and no Bhopal, but there would also have been no penicillin. All science is a trade-off.

Never, ever, compromise on science.

Saying that we should stop nanoscience is tantamount to saying we should stop science.

The laissez-faire attitude to science education has resulted in a disaster exemplified by the fact that more young people are opting for media studies than physics.

Art and science are intrinsically the same except for one thing. The universe is in control of your science, whether it's right or wrong, and the public are in control of your art - if they're going to buy it, if you're going to make a living that way.

Science is based solely on doubt-based, disinterested examination of the natural and physical world. It is entirely independent of personal belief. There is a very important, fundamental concomitant - that is to accept absolutely nothing whatsoever, for which there is no evidence, as having any fundamental validity.
