Ever wondered how the Internet and computers really work but assumed that you wouldn't understand? Did you know that the principle behind the zipper also governed the building of the pyramids? Did you know that the dentist's drill is a direct descendant of the first windmill? David Macaulay has been known as a master explainer ever since the originalThe Way Things Work was published, in 1988. Now he's back with a new edition that includes tons of new material, such as "The Digital Domain," which explains how computers store, process, send, and use information. From movie cameras to virtual reality, flush toilets to photocopiers, Macaulay explains it all.
