Humans needed water or they would die, but dirty water killed as surely as thirst. You had to boil it before you drank it. This culture around tea was a way of tiptoeing along the knife edge between those two ways of dying.

Lawrence immediately saw that it was a trick question. You would have to be some kind of idiot to make the facile assumption that the current would add or subtract 5 miles per hour to or from the speed of the boat.

I really am just trying to tell stories. But stories are often grounded in larger events and themes. They don't have to be - there's a big literature of trailer-park, kitchen-table fiction that's just about goings-on in the lives of ordinary people - but my own tastes run toward stories that in addition to being good stories are set against a backdrop that is interesting to read and learn about.

The story is everything, so it always begins with a story.And research is a kind of scaffolding built underneath the story as I go along. My enjoyment level varies, but in general, I'm writing about topics I find interesting, so I can't gripe too much.

The imperative to develop new technologies and implement them on a heroic scale no longer seems like the childish preoccupation of a few nerds with slide rulers - It's the only way for the human race to escape from its current predicaments - Too bad we've forgotten how to do it

I try to find a style that matches the book. In the Baroque Cycle, I got infected with the prose style of the late 17th and early 18th centuries, which is my favorite era. It's recent enough that it is easy to read - easier than Elizabethan English - but it's pre-Victorian and so doesn't have the pomposity that is often a problem with 19th-century English prose. It is earthy and direct and frequently hilarious.
