Why did you choose to write in your particular field or genre? If
you write more than one, how do you balance them?
I have always been interested in science, which is just as well since I am a scientist, and one of the important aspects of science is that it is based on logic. My feeling is that society these days is approaching some really difficult problems, and clear thinking by as many people as possible is desirable. What I try to do in my stories is show that the winners win by thinking out their problems, and not by sheer luck. In my dreams, I like to think I might influence some people in that way.
Regarding balancing genres, I have entered SF, thrillers, and in two books, historical fiction. The important point for me is that even if the book is hard to categorize, I try to make sure the whole book is unified. By that, I mean everything at the end follows naturally from what was introduced in the beginning. You can have different books with all sorts of differences, but I think it is important that any given book has a unity of purpose.
