    But as the authors of this fascinating and eye-opening book reveal, some of humankind's most important and most amazing inventions actually date back thousands of years. Historian Peter James and archaeologist Nick Thorpe have pooled their expertise in amassing this compendium of human ingenuity through the ages. Together they conclusively prove that our ancestors, however long ago they lived and whatever part of the globe they occupied, were brilliant problem-solvers. Written with the pure joy of discovery, Ancient Inventions reveals that:* Medieval Baghdad had an efficient postal service, banks, and a paper mill.* Rudimentary calendars were being used in France as early as 13,000 B.C.* Apartment condominiums rose in deserts of the American Southwest a thousand years ago.* The ancient Greeks used an early form of computer.* Plastic surgery was being performed in India by the first century B.C.* The Egyptians knew about effective contraceptives.* Flamethrowers were used in battles waged in tenth-century China.Brimming with odd facts and entertaining curiosities, written with zest and humor, comprehensive and fun to read, Ancient Inventions is a wonderful celebration of the endless inventiveness of the human mind."This presentation of the discoveries and innovations of the ancients will fascinate."--Booklist"Thoroughly researched...It is doubtful that anyone could examine [this book] without coming away enlightened in one of its broadly ranging areas."--Library JournalAN ALTERNATE SELECTION OF THE QUALITY PAPERBACK BOOK CLUB AND THE NATURAL SCIENCE BOOK CLUB

    With black and white illustrations and detailed explanations, this comprehensive and visual resource is perfect for young readers interested in history, architecture, and Roman civilization.

    Global sea levels, as the result of rapidly melting polar ice rose by more than 300 feet in a very short period of time, causing the planet to become unstable.In Egypt, Peru, Bolivia, Lebanon and other locations we see the existence of ancient damaged but very sophisticated megalithic stone structures which we would be hard pressed to re-create today. They hint that once upon a time one or "Atlantean" civilizations indeed did exist

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    They have dictated how we build, eat, communicate, wage war, create art, travel, and worship. Some, such as stone, iron, and bronze, lend their names to the ages. Others, such as gold, silver, and diamond, contributed to the rise and fall of great empires. How would history have unfolded without glass, paper, steel, cement, or gunpowder?The impulse to master the properties of our material world and to invent new substances has remained unchanged from the dawn of time; it has guided and shaped the course of history. Sass shows us how substances and civilizations have evolved together. In antiquity, iron was considered more precious than gold. The celluloid used in movie film had its origins in the search for a substitute for ivory billiard balls. The same clay used in the pottery of antiquity has its uses in todayâ€s computer chips.Moving from the Stone Age to the Age of Silicon, from the days of prehistoric survival to the cutting edge of nanotechnology, this fascinating and accessible book connects the worlds of minerals and molecules to the sweep of human history, and shows what materials will dominate the century ahead. 19 color illustrations

    The text is divided into four parts: circuits, electronics, digital systems, and electromagnetics. Although it delves in depth into each of these topics, the text represents more than your basic survey of the basics of electrical engineering. A solid understanding of the fundamental principles on which modern electrical engineering is based is also provided. This edition includes a chapter on circuit analysis software SPICE, with a detailed discussion of the PC version known as PSPICE (from MicroSim Corp.). Numerous drill exercises have been added to this new edition, reinforcing ideas presented in the examples. There are over 1,000 end-of-chapter problems. This text is suitable for a variety of electrical engineering courses. It can be used as a text for an introduction to electrical engineering for both majors and non-majors or both, or can be split and the various chapters utilized for an introduction to circuits course, a first electronics course, or for a course on digital electronics and logic design.

     The Science Book covers every area of science--astronomy, biology, chemistry, geology, math, and physics, and brings the greatest scientific ideas to life with fascinating text, quirky graphics, and pithy quotes.

    By building a network of computers, he believed the government could avoid buying so many new ones for academic research. From these modest Cold War beginnings a global networking industry has flourished, creating virtual communities, online shopping, the ubiquitous e-mail, and immense fortunes. Stephen Segaller's timely book draws on interviews with more than seventy of the pioneers who have used their technological genius and business skills to make incompatible systems work together, to make networking user-friendly, and to create a new global communications medium that rivals the telephone system or television in its scope and reach.Nerds 2.0.1 tells the dramatic, often comical story of how the world's computers have come to be wired together over the last thirty years. This paperback reprint contains new material to update the picture of this still-evolving saga.

    But few of us understand the engineering mindset. It’s the mindset that came up with flatpack furniture, disposable nappies, and the postal code; that solved Stockholm’s traffic and the problem of bank closing times (the hole-in-the-wall); and whose seemingly simple ideas have saved countless lives, with innovations such as painting a line behind traffic lanes and combining GPS with 999. It’s a mindset much like a Swiss-army knife – multipurpose, combining structured and abstract thinking, common sense and great imagination, and cross-pollinating information from every possible sector.With the help of a cast of star engineers and fascinating, unexpected real world examples, Madhavan offers a framework for thinking creatively, systematically and strategically so that we can all learn to make better decisions in a complex world.

    In the 1870s, OTR was comparable to the cultural hearts of Paris and Vienna. By the turn of the last century, the neighborhood was home to roughly three hundred saloons and had over a dozen breweries within or adjacent to its borders. It was beloved by countless citizens and travelers for the exact reasons that others successfully sought to destroy it. This is the story of how the heart of the "Paris of America" became a time capsule.

    Also known as the Yellowstone Earthquake, the disaster caused massive flooding and the worst landslide in the history of the Northwestern United States. In The Night the Mountain Fell author Edmund Christopherson gives us a page-turning, journalistic-style account of how the deadliest earthquake in Montana's history ultimately claimed the lives of twenty-eight people.

    The Lockheed SR-71 Blackbird spy plane flew more than three-and-a-half times the speed of sound--so fast that no other aircraft could catch it. Above 80,000 feet, its pilots had to wear full-pressure flight suits similar to what was used aboard the space shuttle.Developed by the renowned Lockheed Skunk Works, the SR-71 was an awesome aircraft in every respect. It was withdrawn from use in 1998, when it was superseded by satellite technology. Twelve of the thirty-two aircraft were destroyed in accidents, but none were ever lost to enemy action.Throughout its thirty-four-year career, the SR-71 was the world's fastest and highest-flying operational manned aircraft. It set world records for altitude and speed: an absolute altitude record of 85,069 feet and an absolute speed record of 2,193.2 miles per hour.The Complete Book of the SR-71 Blackbird covers every aspect of the SR-71's development, manufacture, modification, and active service from the insider's perspective of one of its pilots and is lavishly illustrated with more than 400 photos. Former pilot and author Richard Graham also examines each of the fifty planes that came out the SR-71 program (fifteen A-12s; three YF-12s; and thirty-two SR-71s) and tells each plane's history, its unique specifications, and where each currently resides.

    From the tenth to the fifteenth centuries the earth experienced a rise in surface temperature that changed climate worldwide—a preview of today's global warming. In some areas, including Western Europe, longer summers brought bountiful harvests and population growth that led to cultural flowering. In the Arctic, Inuit and Norse sailors made cultural connections across thousands of miles as they traded precious iron goods. Polynesian sailors, riding new wind patterns, were able to settle the remotest islands on earth. But in many parts of the world, the warm centuries brought drought and famine. Elaborate societies in western and central America collapsed, and the vast building complexes of Chaco Canyon and the Mayan Yucatan were left empty.As he did in his bestselling The Little Ice Age, anthropologist and historian Brian Fagan reveals how subtle changes in the environment had far-reaching effects on human life, in a narrative that sweeps from the Arctic ice cap to the Sahara to the Indian Ocean. The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives today—and our vulnerability to drought, writes Fagan, is the "silent elephant in the room."Learn more at www.brianfagan.com.Brian Fagan discusses The Great Warming on The Daily Show with John Stewart.PRAISE for The Great Warming:"This is not only World History at its best, sweeping across all of humankind with a coherent vision, but also a feat of imagination and massive research. If Fagan has given the medieval period throughout the globe a new dimension, he has at the same time issued an irrefutable warning about climate change that is deeply troubling."—Theodore Rabb, author of The Last Days of the Renaissance"Climate has been making history for a very long time, though historians have rarely paid much attention to it. But as it turns out, a few less inches of rain, a change in temperature of just a degree or two can make all the difference in how human events unfold. The Great Warming demonstrates that although human beings make history, they very definitely do not make it under circumstances of their own choosing.”—Ted Steinberg, author of Down to Earth: Nature’s Role in American History and American Green: The Obsessive Quest for the Perfect Lawn
