The sun shines on the Earth and keeps it warm.We have day and night because the Earth spins on its axis and we spend part of each day facing the sun and part of the day facing away from it. But why are days longer in the summer than in the winter? The answer to this question is explained through an experiment using a pencil, an orange, and a flashlight. And when you see this, you'll know the reasons for the seasons.

    More unusually, they were at the time travelling together from Moscow to Vancouver by human power — boat, bike, and foot. That day, they were examining a road atlas and in particular the labyrinth of European inland waterways it revealed. Julie traced a route of interconnected canals, rivers, and coastlines that led from Colin’s parents’ homeland of Scotland past her mother’s homeland, Germany, and on to her father’s, Syria. She said, half-seriously: We could row (yes, row, as in propelling a tippy little boat on a pond) all the way from Scotland to Syria to visit our relatives. It was a reckless sort of joke to make, given the couple’s addiction to adventure. The result is Rowed Trip, an odyssey by oar (and bike) from Caithness, Scotland, across the English Channel, through France, across the Rhine, the Main-Donau Canal to the Danube, the Black Sea, the Bosphorous Straits, and the Mediterranean. Julie and Colin each describe how the trip allowed them to test their relationship, to explore their roots, and to indulge to the max their shared taste for adventure.

    But how many of us appreciate the ways our bodies also depend on phosphorous, say, to hold our DNA together, or potassium to power our optic nerves so that we can see? In The Human Elements, physicist and award-winning author Anja Røyne takes us on an astonishing journey through chemistry and physics, introducing the building blocks from which we humans—and the world—are made. Not only does Røyne explain why our bodies need iron, phosphorus, silicon, potassium, and many more elements in just the right amounts in order to function properly; she also takes us on a tour around the world to where these precious elements are found (some of them in ever-shrinking quantities). Røyne makes us understand how precarious the balance that keeps us and our environment alive really is, how there are finite amounts of our life-giving elements available to us, and how, from the smallest to the grandest scale, the world and everything that lives in it are wonderfully interconnected. The Human Elements will make you look at the world and your place in it in an entirely new way.

    With amusing examples from film, TV, and history, learn how physics affects everything in your surroundings--without the use of mind-bending math or the need for a particle accelerator. With E=MC2, you'll learn: When forces balance: Simple answers to questions such as, "Why do balloons rise while apples fall?" The Good, the Bad, and the Impossible: Why The Good, the Bad, and the Ugly is full of absurdities. (For someone whose characters often uphold the law, Clint Eastwood certainly defies the laws of physics in this film.) AC/DC: but only AC really rocks: Alternating current (AC) is much more complicated than direct current (DC). The voltage is constantly moving between positive and negative; the current therefore flows one way, and then the other (rocking back and forth). Why do I feel this warm glow?: The theory behind how the first stars were born General Relativity and GPS: The strange result of gravity on time is well proven. Compared to the interminable time you experience while stuck in a traffic jam, time literally runs faster (because gravity is weaker) in the orbiting GPS satellites that help your GPS system get its fix. At the speed of light: A refresher on the theory of relativity and an understanding of why--a hundred years later--Einstein's physics still points the way in cutting-edge research. Yu again: In the martial arts movie Crouching Tiger, Hidden Dragon, the rebellious young heroine, Jen Yu, blocks an attacker with her hand without standing or bracing herself. All the while, she holds a cup of tea in her other hand and doesn't spill a drop. Find out why kinetic energy and scalar quantity make her move impossible. It's physics for the rest of us. So why not come along for the ride? Advance at the speed of light through the fundamental laws of physics as they were discovered, proven wrong, and revolutionized.

    A nightmare in the rear-view mirror. A unique winner in the boardroom. A seven-time Winston Cup champion. A driver whose personal success story and dedication inspired the adoration of millions of fans. Then on February 18, 2001, just seconds from the Daytona 500 finish line, the world of stock-car racing suffered a devastating loss as Dale Earnhardt fatally careened into a track wall. The tragic shock waves, and an unprecedented outpouring of respect and love, have not stopped since.At the Altar of Speed takes readers behind the scenes of Earnhardt's celebrated life, tracing his rags-to-riches journey to the top of America's fastest-growing sport. Beginning with Earnhardt's early days growing up in small-town North Carolina, veteran sports writer Leigh Montville examines how a ninth-grade dropout started on the dusty dirt tracks of the South, went through two marriages and a string of no-future jobs before turning twenty-five, then took about a million left turns to glory. Through the pitfalls and triumphs, Earnhardt would ultimately become a celebrated champion, whose lifetime earnings would top forty-one million dollars. The son of a legendary racer, the father of a NASCAR star, he lived a total auto-racing life filled with triumph and sadness, great joy and great pain.Transporting readers to the colorful, noisy world of stock-car racing, where powerful engines allow drivers to reach speeds of 200 m.p.h., At the Altar of Speed vividly captures the man who drove the black No. 3 car, a man whose determination and inner strength left behind a legacy of greatness that has redefined his sport. Illustrated with a section of full-color photographs, At the Altar of Speed is a tribute to both the man and his unbeatable spirit.

    Meet a man who can pull two railroad passenger cars with his teeth and a real-life human cannon ball. Come face to face with a dead rattlesnake that still bites. And unlock the secrets of a magician's bodiless head. Welcome to this updated edition of The Flying Circus of Physics, where death-defying stunts, high-flying acrobatics, strange curiosities, and mind-bending illusions bring to life the fascinating feats of physics in the world around us. In 1977, Wiley published the first edition of Jearl Walker's The Flying Circus of Physics, which has sold over 100,000 copies and become a cult classic in the physics community. The Flying Circus is a compendium of interesting real world phenomena that can be explained using basic laws of physics. This new edition represents a thorough updating and modernization of the book. The new edition gives us the opportunity to highlight Jearl's creativity, his communication skills, and his ability to make physics interesting.Jearl Walker, Ph.D., professor of physics at Cleveland State University and the man who frequently walked on hot coals and lay on beds of nails all in the name of science, is the first recipient of the Outstanding Teaching Award from Cleveland State's College of Science. The College's Faculty Affairs Committee selected Dr. Walker as the first honoree based on his impressive contributions to science teaching over the last 30 years. In fact, the award in future years will be named the Jearl Walker Outstanding Teaching Award in recognition of his many achievements.Jearl Walker received his B.S. in physics from MIT in 1967 and his Ph.D. in physics from the University of Maryland in 1973. His popular book, The Flying Circus of Physics, has been translated into at least 10 languages and is still being sold worldwide. For 16 years he toured his fun-filled Flying Circus lecture throughout the U.S. and Canada, introducing countless teachers to such physics phenomena as molecular adhesion by hanging spoons from his face and Leidenfrost's phenomenon by dipping his wet hand in molten lead without getting hurt.These lectures led to his national PBS television show, Kinetic Karnival, which ran for several years and won him a local Emmy Award. During his 13 years as a columnist with Scientific American magazine, Dr. Walker wrote 152 articles for The Amateur Scientist section, which were translated into at least 9 languages worldwide. His topics ranged from the physics of judo to the physics of bearnaise sauce and lemon meringue pie. In 1990, he took over the textbook Fundamentals of Physics from David Halliday and Robert Resnick and has now published the seventh edition of the book. He has appeared countless times on television and radio and in newspapers and magazines.

    As Lord Shackleton, former president of the Royal Geographical Society, said of an earlier edition, it is "the finest reference atlas ever published." Now, The Times Atlas of the World, Tenth Comprehensive Edition, the first completely revised edition since The Times Atlas of the World debuted in 1967, establishes an even higher standard among all reference atlases, and a new benchmark in its own unparalleled tradition. The Tenth Comprehensive Edition opens with stunning satellite images of the continents and the oceans as they appear from space. This preliminary section continues with a series of graphics, photographs, maps, tables, and charts reviewing the cosmos, the natural world, and humanity's interaction with our home planet. Next is a comparative list of Earth's physical features, from rivers to mountains to islands to deserts, and a complete statistical guide to the states and territories of the world. This opening section concludes with a fascinating chronicle on the evolution of world mapping, beginning with our first attempt to map the world more than a thousand years ago. The central section of The Tenth Comprehensive Edition, with 248 pages of breathtakingly detailed reference maps, provides the most accurate and up-to-date visual presentation of geographical knowledge in any atlas today. Each map, drawn with generous scale and projection, has been entirely redesigned since the last edition, using the latest digital technology. While creating maps of optimum accuracy, these new methods also provide enhanced clarity and greater legibility than ever before, even for an atlas that was already legendary for the readability of its maps. In addition to recording the new states and republics created by political upheaval in this last decade before the millennium, The Tenth Comprehensive Edition includes a multitude of renamed towns and cities, along with many revised national borders. The revised and expanded index, covering more than 200,000 place names, is the largest index ever found in a single-volume atlas, virtually ensuring that any location a reader may be looking for will be included in the book. The index is also unique in scope, giving the name, description, regional and country locations, the map grid reference, page number, and latitude and longitude. No other atlas comes close to providing such an index, either in sheer numbers or in reference value.In the last three decades, The Times Atlas of the World has been in the vanguard of a revolution in the science of cartography, replacing maps formerly created on hand-etched copper plates with maps that are computer-generated. The Times Atlas of the World, Tenth Comprehensive Edition, represents the fullest flowering yet of this remarkable revolution in cartography. It is the finest atlas ever published, sure to be treasured by students, scholars, armchair travelers, global sightseers, and anyone seeking better understanding of our dynamic planet.
