Leibniz is at the disadvantage of not having seen it. Or perhaps we should count this as an advantage, for anyone who sees it is dumbfounded by the brilliance of the geometry, and it is difficult to criticize a man’s work when you are down on your knees shielding your eyes.

Wired people should know something about wires.

Most of my colleagues go on backpacking trips when they have to do some thinking. I go to a good hardware store and head for the oiliest, dustiest corners... If they're really good, they don't hassle me. They let me wander around and think. Young hardware clerks have a lot of hubris. They think they can help you find anything...

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.
