*** RUST ***
In case you didn't know, I'm working on a book about rust, and all of the ingenious/pathetic things we do to keep metal from doing what it wants to do. I often think of the book as the story of the amazing effort to save modern society's most important material. It's a pretty big story, I think, and super cool.
There's more at The Story of Rust.
