Looking at the technology all around us-and then explaining how it
works, the How Things Work Encyclopedia lifts the hood of a car
engine, gets inside a TV set, and discovers the power of invisible
microwaves. With close-ups, cutaways, and diagrams bringing the
technology to life, and timelines illustrating the development of
inventions, challenging curiosity quizzes and fascinating facts, the
How Things Work Encyclopedia lets children really see and understand
what's going on inside.
