Anodizing (Or the beauty of corrosion)

Bill describes how metals like aluminum and titanium are made resistant to corrosion by growing an oxide layer into the metals. These is the same process used on many Apple products. This video is based on a chapter in the book Eight Amazing Engineering Stories; learn more at http://www.engineerguy.com/elements.

Rust is oxidized iron or steel not other metals oxidizing. He is wrong.

Just as organisms of the same species can evolve over time without having contact with each other, languages that span two countries can differ greatly over time. Creoles are a good example of the evolution of languages over time. In the case of creoles, however, two languages are melded to form a distinct "hybrid" language. The difference between English in the UK and English in the US is a result of the natural evolution of languages, not out of a desire to differ from the rest of the world.
