Answer:
No-one's ever likely to mistake me for Michelangelo, but I have at least one thing in common with that famous Renaissance artist: both of us have used art to communicate important things to other people. In Michelangelo's case, it was stunning paintings and sculptures; my own contribution to art history has been far more mundane: over the last decade or two, I've had to produce dozens of diagrams to illustrate the books and web pages I've written about science and technology.
Much of the time I've had superb artists and illustrators to help: I've just roughed out a basic sketch and they've done all the clever stuff for me. Recently, since I've been writing more for the web, I've produced most of my own art as well, which means I've had to learn to draw scientific and technological things far better than ever before. That's been a real challenge, because I've never been good at art. Fortunately, scientific art is very different from real, artistic art and, even if you've as little artistic talent as me, you can still do a passable job of communicating your ideas if you use a decent computer graphics package. So what's the secret? Here are some of the tips I've picked up over the years that I'd like to share with you now.
