Thus we learn about plate tectonics, rock and mountain formation, fluid mechanics and glaciers. Trefil also discusses black holes and satellites, rockets and meteorites. Near timberline, his discovery of twisted trees (right- and left-handed) elicits an explanation of what happens when the symmetry of nature is broken. This is an illuminating excursion into the physical world of mountains. Illustrations not seen by PW. Copyright 1986 Reed Business Information, Inc. From Library Journal Observations made while hiking in the Rockies are a springboard for Trefil's discussions of the physics behind the phenomena in our physical world. Whether he is explaining neutron sta bility, radioactive dating of rocks and fossils, or the anomalous behavior of the water we take so much for granted, the author exhibits an unusual flair for clarifying the complex and offering sur prises. His seventh collection of essays is eminently readable and wide-rang ing, an excellent science popularization.
