Paperback. Condizione: New. This book sets forth a set of truly controversial and astonishing theories: First, it proposes that below the surface of the earth is a biosphere of greater mass and volume than the biosphere the total sum of living things on our planet's continents and in its oceans. Second, it proposes that the inhabitants of this subterranean biosphere are not plants or animals as we know them, but heat-loving bacteria that survive on a diet consisting solely of hydrocarbons that is, natural gas and petroleum. And third and perhaps most heretically, the book advances the stunning idea that most hydrocarbons on Earth are not the byproduct of biological debris ("fossil fuels"), but were a common constituent of the materials from which the earth itself was formed some 4.5 billion years ago.The implications are astounding. The theory proposes answers to often-asked questions: Is the deep hot biosphere where life originated, and do Mars and other seemingly barren planets contain deep biospheres? Even more provocatively, is it possible that there is an enormous store of hydrocarbons upwelling from deep within the earth that can provide us with abundant supplies of gas and petroleum?However far-fetched these ideas seem, they are supported by a growing body of evidence, and by the indisputable stature and seriousness Gold brings to any scientific debate. In this book we see a brilliant and boldly original thinker, increasingly a rarity in modern science, as he develops potentially revolutionary ideas about how our world works.

Paperback. Condizione: New. Just 12,000 years ago - at the height of the last Ice Age - saber-toothed tigers, giant ground sloths, camels, hippos and the great herds of proboscideans: giant mastodons and mammoths, extinct relatives of the elephant, roamed the land where skyscrapers now stand. Why are these splendid creatures no longer with us? This compelling book explores the reasons for these extinctions and provides a tour of mass extinctions throughout earth's history, including the great comet crash that killed off the dinosaurs. Brilliantly written, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force.

The material in this book forms the basis of an interdisciplinary, college-level course, which uses science fiction film as a vehicle for exploring science concepts. Unlike traditional introductory-level courses, the science content is arranged according to major themes in science fiction, with a deliberate progression from the highly objective and discipline-specific (e.g. Reference Frames; Physics of Space Travel and Time Travel) to the very multi-disciplinary and thought-provoking (e.g. Human Teleportation; Science and Society). Over 100 references to science fiction films and television episodes are included, spanning more than 100 years of cinematic history. Some of these are conducive to calculations (solutions included).

It founded the field of biogeochemistry and is one of the seminal works in what is now known as Gaia theory. This edition, the first unexpurgated English translation, is fully annotated for the modern reader.

The sweeping diversity of complex life on Earth, Ward and Brownlee argue, evolved out of an extraordinary set of physical conditions and chance events that would be extremely hard to duplicate--though not impossible. Many planets throughout the vastness of the Universe may be teeming with microbial life, but advancement beyond this stage is very rare. Everyone with an interest in the possible extent of life in the Universe and the nature of life's evolution on our own planet will be fascinated by Rare Earth.

Imagine living during the Renaissance and being able to interview that era's greatest scientists about their inspirations, discoveries, and personal interests. The latter half of our century has seen its own Renaissance--informations technology has changed irrevocable the way we live, work, and think about the world. We are fortunate, therefore, that the authors of Out of Their Minds have been able to talk so candidly with the founders of computer science.
