A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet. Contrary to their reputation, rocks have eventful lives—and they intersect with our own in surprising ways.

Ranging from prehistory to the 21st century, The Great Sea is above all the history of human interaction across a region that has brought together many of the great civilizations of antiquity as well as the rival empires of medieval and modern times.

More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working today - and one of the very few women in her field - Into the Planet blends science, adventure, and memoir to bring listeners face-to-face with the terror and beauty of Earth’s remaining unknowns and the extremes of human capability.

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

In his last book, Neil Shubin delved into the amazing connections between human anatomy—our hands, our jaws—and the structures in the fish that first took over land 375 million years ago. Now, with his trademark clarity and exuberance, he takes an even more expansive approach to the question of why we are the way we are.

To many of us, the Earth's crust is a relic of ancient, unknowable history. But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the listener along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.

Exploring Creation with General Science: 3rd Edition is part of Apologia's line of award-winning homeschool science curriculum. It has been rewritten to truly walk each student through middle school's transition time from the elementary years to the high school sciences. Specifically designed to be the first course taken during junior high, it was created to give middle school students a basic understanding of the world that surrounds them each day of their lives so that they can appreciate the real-world relevance of scientific inquiry and the beauty of creation.

Para Lewis Dartnell la única manera de comprender nuestra historia consiste en explicar cómo nuestro planeta, desde el inicio de los tiempos, ha determinado nuestro destino. Toda especie está condicionada por su entorno.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. In spite - or even because - of the disgraceful hostility provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.

Hace unos 4.000 millones de años apareció la vida en la Tierra. ¿Cuál es la historia de su evolución? ¿Era inevitable la vida? ¿Y la raza humana? ¿La habría habitado algún otro ser inteligente, si no hubiera habido humanos? ¿Qué patrones usa el mecanismo evolutivo? ¿La evolución avanza hacia adelante como una flecha?

The earth has died many times, and it always comes back looking different. In an exhilarating, surprising exploration of our planet, Craig Childs takes listeners on a firsthand journey through apocalypse, touching the truth behind the speculation. Apocalyptic Planet is a combination of science and adventure that reveals the ways in which our world is constantly moving toward its end and how we can change our place within the cycles and episodes that rule it.

On 30 January, 1981 Joe Tasker and Ade Burgess stood at 24,000 feet on the west ridge of Mount Everest. Below them were their companions, some exhausted, some crippled by illness, all virtually incapacitated. Further progress seemed impossible. Everest the Cruel Way is Joe Tasker's story of an attempt to climb the highest mountain on earth - an attempt which pushed a group of Britain's finest mountaineers to their limits. The goal had been to climb Mount Everest at its hardest: via the infamous west ridge, without supplementary oxygen and in winter.

Exploring Creation with Physical Science, 3rd Edition was created to give middle school students an understanding of the basic world that surrounds them each day of their lives and the forces in creation so that they can appreciate the real world relevance of scientific inquiry and the beauty of creation. We believe that students’ educations should prepare them for life, not just an academic year.

In this fresh and powerful work of environmental history, Martin Doyle explores how rivers have often been the source of arguments at the heart of the American experiment - over federalism, taxation, regulation, conservation, and development. Doyle tells the epic story of America and its rivers, from the US Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina.
