My grandmother flew only once in her life, and that was the day she and her new husband ascended into the skies of Victorian London in the wicker basket of a hot-air balloon. They were soon to emigrate to Canada, and the aerial ride was meant to be a last view of their beloved England.

I'm at that age where I watch such things with two minds, one that cackles at these capers and another that never gets much beyond a rather jaded and self-conscious smile, like the Mona Lisa.

What intrigued me more than anything else was finding out the way in which everything, all of creation - all of it! - was held together by invisible chemical bonds, and I found a strange, inexplicable comfort in knowing that somewhere, even though we couldn't see it in our own world, there was a real stability.

Chicken fizz! O Lord, protect all of us who toil in the vineyards of experimental chemistry!

I always knew that I wanted to work on my own material - something that would be more long-lasting than short-lived electronic transmissions.

Except I'm aware that as a writer you can't get away with as much writing for children as you can with adults. Children have much more finely tuned senses of justice, morals, and ethics. They are much more Platonic: children are symmetrical, before we begin to fragment them with our own nonsensical ideas and squelch their natural joy in knowledge.
