The Universe Within
Discovering the Common History of Rocks, Planets, and People
1st Edition Hardcover ISBN: 0307378438
From one of our finest and most popular science writers, the best-selling author of Your Inner Fish, comes the answer to a scientific mystery story as big as the world itself: How have astronomical events that took place millions of years ago created the unique qualities of the human species? 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. Starting once again with fossils, Shubin turns his gaze skyward. He shows how the entirety of the universe's 14-billion-year history can be seen in our bodies. From our very molecular composition (a result of stellar events at the origin of our solar system), he makes clear, through the working of our eyes, how the evolution of the cosmos has had profound effects on the development of human life on earth.
Great Moments in the History of Hard, Cold Water
1st Edition Hardcover ISBN: 0873516281
"Put your mittens on; you'll freeze to death!" admonish the world's grandmothers as the temperature plummets. No doubt the Arctic explorers--today in their GORE-TEX, historically in their woolens--needed no such instruction. Icy climes bring with them the dangers of frostbite, but also the poetic beauty of glaciers and ice shelves, of ice palaces and aurora borealis. Karal Ann Marling explores these topics and more as she considers the history of "hard, cold water." What better place to start than with dessert? The pleasure of ice cream on a hot day has been known since the sixteenth century, although it wasn't until a few hundred years later that reliable refrigeration made the treat readily available. Marling expands her icy explorations to the realm of fiction--the ice crossing in Uncle Tom's Cabin, the frozen wasteland of Frankenstein--and to the movies and Broadway. Cities vie for tourists by building shimmering ice palaces to celebrate winter; explorers compete to reach the poles, and not all live to tell the story. The study of ice by a true aficionado yields fascinating insights and may just inspire readers to embrace winter-or to make their way to the nearest ice cream shop. Karal Ann Marling is a professor emerita of art history and American studies at the University of Minnesota. She is the author, most recently, of Merry Christmas!: Celebrating America's Greatest Holiday and Illusions of Eden: Visions of the American Heartland.

Dark Matter and the Dinosaurs
The Astounding Interconnectedness of the Universe
Paperback ISBN: 0062328506
In this brilliant exploration of our cosmic environment, the renowned particle physicist andNew York Times bestselling author of Warped Passages and Knocking on Heaven’s Dooruses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. 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? InDark 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. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.

The Map That Changed the World
William Smith and the Birth of Modern Geology
Paperback ISBN: 0061767905
In 1793, a canal digger named William Smith made a startling discovery. He found that by tracing the placement of fossils, which he uncovered in his excavations, one could follow layers of rocks as they dipped and rose and fell—clear across England and, indeed, clear across the world—making it possible, for the first time ever, to draw a chart of the hidden underside of the earth. Smith spent twenty-two years piecing together the fragments of this unseen universe to create an epochal and remarkably beautiful hand-painted map. But instead of receiving accolades and honors, he ended up in debtors' prison, the victim of plagiarism, and virtually homeless for ten years more. The Map That Changed the World is a very human tale of endurance and achievement, of one man's dedication in the face of ruin. With a keen eye and thoughtful detail, Simon Winchester unfolds the poignant sacrifice behind this world-changing discovery.
