"It is the largest thing we have ever built," says Whitesides, "and we have assembled it from transistors--the smallest things we know how to make. It is a chrysalis we are forming around the planet...a table where we sit to gossip, a suq where we buy and sell; a shadowy corner for planning mischief; a library holding the entire world's information; a friend, a game, a matchmaker, a psychiatrist, an erotic dream, a babysitter, a teacher, a spy....The best and worst and most ordinary of us reflected--and perhaps distorted--in a silvery fog of bits."
--George Whitesides describing the Internet, in No Small Matter: Science on the Nanoscale.
There's a great review of George Whitesides' and Felice Frankel's new book, No Small Matter: Science on the Nanoscale, in the Jan/Feb issue of Harvard Magazine. It's definitely worth a look, not least because it's accompanied by about a dozen beautiful photos. (I haven't seen the book myself, but I have On the Surface of Things, Frankel's previous book, and it's lovely.)
