This book follows the historical trail by which humanity has determined the shape and internal structure of the Earth. It is a story that bears on aspects of the history of science, the history of philosophy and the history of mathematics. At the heart of the narrative is the important philosophical practice of performing thought experiments — that is, the art of considering an idealized experiment in the mind. This powerful technique has been used by all the great historical practitioners of science and mathematics, and this book looks specifically at the long history of considering what would happen if an object could be dropped into a tunnel that cuts all the way through the Earth's interior. Indeed, the story begins with a historical whodunit, tracing back through the historical literature the origins of what is now a classic, textbook problem in simple harmonic motion.
Science has its roots in human curiosity. It is the process of exploration and research that has led to a better understanding of our surroundings: Copernicus set the Earth in its right place in our models of the Universe, Charles Darwin elucidated the mechanism of the evolution of living species, and Albert Einstein brought out the intimate connection between energy, space, and time.This book provides a reliable guide to acquaint oneself with the scientific process. It explains in easy terms how scientific investigation has historically developed to reach our present understanding of the world around us. It also discusses the place of science in modern society in relation to culture and to the technological advances that it brings.
TERRAFORMING MARS This book provides a thorough scientific review of how Mars might eventually be colonized, industrialized, and transformed into a world better suited to human habitation. The idea of terraforming Mars has, in recent times, become a topic of intense scientific interest and great public debate. Stimulated in part by the contemporary imperative to begin geoengineering Earth, as a means to combat global climate change, the terraforming of Mars will work to make its presently hostile environment more suitable to life—especially human life. Geoengineering and terraforming, at their core, have the same goal—that is to enhance (or revive) the ability of a specific environment to support human life, society, and industry. The chapters in this text, written by experts in their respective fields, are accordingly in resonance with the important, and ongoing discussions concerning the human stewardship of global climate systems. In this sense, the text is both timely and relevant and will cover issues relating to topics that will only grow in their relevance in future decades. The notion of terraforming Mars is not a new one, as such, and it has long played as the background narrative in many science fiction novels. This book, however, deals exclusively with what is physically possible, and what might conceivably be put into actual practice within the next several human generations. Audience Researchers in planetary science, astronomy, astrobiology, space engineering, architecture, ethics, as well as members of the space industry.
Hurtling through the atmosphere, in a blaze of light and reverberating percussions, the arrival of a meteorite on Earth is a magical, rare, and precious sight. These characteristics have accordingly ensured a long, yet often controversial history. For all this, meteorites are cosmic messengers. They tell us about the entire history of the solar system, their story carrying us from the very earliest moments, when solid material first began to form in the solar nebula. Indeed, meteorites played a key role in the origins of Earth's oceans and the genesis of life. Meteorites additionally tell us about the origin and evolution of the asteroids, and they tell us about impacts upon the Moon as well as the volcanic history of planet Mars. Much is known about the structure and chemistry of meteorites, but for all this, they still harbor many scientific mysteries that have yet to be resolved.
Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

Fourteen-year-old Jackson Elderberry Monroe is an indigo with unusual abilities. Due to acceleration codes imbedded in his DNA, he is picked by a group of Guardian extraterrestrials to help protect the planet Earth from sinister alien technology deliberately designed to pull Earth into a black hole in the center of the galaxy. The Guardian extraterrestrials choose TeTe, a strangely weird but wise representative from the sixth dimension to prepare and train the young indigo for what portends to be a very dangerous time travel mission and to open his mind to the true history of the planet, which has been safely kept on selenite crystals until now. Intrigued by an adventure that includes taking hyperspace leaps while transcending time, making new alien friends, and indulging in off planet retrieval missions and recreational opportunities, Jackson decides to give the training program a try. Now only time will tell if Jackson and the Guardian team will be successful in altering the timeline of Earths fall. Why Me? is the continuing science fiction tale of a gifted teenagers journey through hyperspace, with the help of an alien mentor, in an effort to save Earth from a horrifying fate.
