If you've ever wondered how a neon light works, how food cooks, or why dust settles on the moving blades of a fan, this is an excellent place to find out. Professor Louis Bloomfield of the University of Virginia Physics Department urges users to "think of this site as a radio call-in program that's being held on the WWW instead of the radio." Users email questions about how things work and he answers them. A browsable and searchable list of answered questions is arranged (in nineteen major chapters, from The Laws of Motion to Resonance to Light) in accordance with a companion book HOW THINGS WORK: The Physics of Everyday Life. Note that at times the question box may be full.
