Bennett, John G.

"Energy is the only universal currency. One of its many forms must be transformed into another in order for stars to shine, planets to rotate, living things to grow, and civilizations to evolve." "In this book, ecologist Vaclav Smil takes the principle of universality seriously, presenting a comprehensive and integrated survey of all the forms of energy that shape our world, from the sun to the human body, from bread to microchips. Each essay explains the science of the energy form as well as its implications for the functioning of the universe, life, or human society. Cross-links and summary diagrams allow easy comparisons among the various levels and flows of energy."--Jacket.

Bestselling, award-winning futurist David Brin returns to globe-spanning, high concept SF with Existence. Gerald Livingstone is an orbital garbage collector. For a hundred years, people have been abandoning things in space, and someone has to clean it up. But there’s something spinning a little bit higher than he expects, something that isn’t on the decades’ old orbital maps. An hour after he grabs it and brings it in, rumors fill Earth’s infomesh about an “alien artifact.” Thrown into the maelstrom of worldwide shared experience, the Artifact is a game-changer. A message in a bottle; an alien capsule that wants to communicate. The world reacts as humans always do: with fear and hope and selfishness and love and violence. And insatiable curiosity.

from the Foreword: These six lectures, delivered in England more than a quarter of a century ago, were among the earliest of J. G. Bennett's presentations of systematics. They are characterized by the author's customary clarity and his simplicity in the presentation of complex ideas. His examples of the working of systems range from writing with chalk on a blackboard to the revolution of the planets. ... Elizabeth Bennett June, 1990
