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 today is a highly collaborative exercise, and to convert it into a contest, as the Nobel does, is a bad way to look at science.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.

Sometime in the future, science will be able to create realities that we can't even begin to imagine. As we evolve, we'll be able to construct other information systems that correspond to other realities, universes based on logic completely different from ours and not based on space and time.

We also had to bring with us some desired scientific equipment over to the station as well as assemble new machines. For that, I had to conduct two space walks.
