Time for another hideous chemistry lesson. No one requested a tutorial on this interesting metal. But guess what -- you got one anyhow! Palladium, named after a Greek goddess and worth more than gold, also keeps our air clean. There's plenty of interesting stuff you'll learn here (if you can stand to read this).
