An Illustrated Guide to Relativity

Who has not gazed with wonder at the night sky, especially from a dark site far away from city lights? The great canopy of stars stretching overhead suggests that our world is part of a vastly larger cosmos. But how large is it? Where do we fit in? And how did it all begin? These questions have puzzled stargazers for thousands of years, and the search for answers helped spark the great advances of the scientific revolution in the 16th and 17th centuries. But only in our own time has the full picture of the true immensity, variety, and surpassing strangeness of the Universe come into focus.

This series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical re-enactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories.

A few hundred miles above Earth, there is a remarkable telescope with a crystal-clear view across the universe. For two decades, the Hubble Space Telescope has been amassing discoveries that rival those of history's greatest scientists and explorers, making it the most important and productive scientific instrument ever built.
