Traces of Time: The Beauty of Change in Nature: An Exploratorium Book

Nature tells stories that unfold over time, and the evidence is all around us—in the shape of a rugged coastline, in the growth of a tree's rings, in the beautiful banded strata of an ice cave. The latest book from The Exploratorium, San Francisco's acclaimed hands-on science museum, combines William Neill's award-winning photography with accessible scientific observation to illuminate an ever-changing world. Examining nature in segments of time ranging from a fraction of a second to millions of years, from the bloom of a plant to the carving of a canyon, Traces of Time reveals how to measure the forces of nature and the ways they affect our planet. A powerful portrait of the natural beauty of our world, this gorgeous blending of art, science, and photography offers a new perspective to anyone who has ever gazed at the world in wonder.
