Don't keep rewriting and polishing something if it isn't setting the world on fire: start something new instead and consider the earlier story a learning experience.

I watched 'Who' with a mixture of affection and exasperation through the eighties, always ready to cheer on the Doctor but seldom feeling that the series was playing to its strengths. Some of the adventures, revisited on DVD, turn out to be better than I remembered - others just as infuriating.

I've always loved far future SF, so it was more or less a given that I would one day want to write in that form.

I don't know why, but American sci-fi writers seem to focus on the near-future, which has given us Brits a clear run at the most fascinating.

Science is the systematic classification of experience.

I spend time in the classroom. I think more of them aren't political science than are political science. I particularly like talking to journalism students.

The discovery of the Quantized Hall Effect (QHE) was the result of systematic measurements on silicon field effect transistors - the most important device in microelectronics.

I wrote the very first stories in science fiction which dealt with homosexuality, The World Well Lost and Affair With a Green Monkey.
