    It is revealed how all unifications in physics have been based on incredibly simple ideas. Using a logical approach, it is explained how the great 20th century theories of relativity and quantum mechanics share a common base, and how they can be linked using an idea so simple that anyone can understand it. An idea which is so simple it has been hidden in plain sight.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    Following on the success of the first six editions of the series, this work introduces theoretical and pedagogical innovations in statics, dynamics, and mechanics of materials education.

    In this unconventional introduction, physicist Leonard Susskind and hacker-scientist George Hrabovsky offer a first course in physics and associated math for the ardent amateur. Unlike most popular physics books—which give readers a taste of what physicists know but shy away from equations or math—Susskind and Hrabovsky actually teach the skills you need to do physics, beginning with classical mechanics, yourself. Based on Susskind's enormously popular Stanford University-based (and YouTube-featured) continuing-education course, the authors cover the minimum—the theoretical minimum of the title—that readers need to master to study more advanced topics.An alternative to the conventional go-to-college method, The Theoretical Minimum provides a tool kit for amateur scientists to learn physics at their own pace.

    Yet The Origin of Species (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and—by implication—within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, The Origin of Species remains one of the founding documents of the modern age.

    She was right about one of them. This story first appeared in the anthology CHANGING THE WORLD in 2009.

    Incorporating biological, medicinal, and environmental applications, it builts an art program. Highlighting the art program are micro-to-macro art pieces that visually guide students to conceptually understand organic chemistry.

    Jim Bradbury explores the full military background of the battle and investigates both what actually happened on that fateful day in 1066 and the role that the battle plays in the British national myth. The Battle of Hastings starts by looking at the Normans—who they were, where they came from—and the career of William the Conqueror before 1066. Next, the narrative turns to the Saxons in England, and to Harold Godwineson, successor to Edward the Confessor, and his attempts to create unity in the divided kingdom. This provides the background to an examination of the military development of the two sides up to 1066, detailing differences in tactics, arms, and armor. The core of the book is a move-by-move reconstruction of the battle itself, including the advance planning, the site, the composition of the two armies, and the use of archers, feigned retreats, and the death of Harold Godwineson. In looking at the consequences of the battle, Jim Bradbury deals with the conquest of England and the ongoing resistance to the Normans. The effects of the conquest are also seen in the creation of castles and developments in feudalism, and in links with Normandy that revealed themselves particularly in church appointments. This is the first time a military historian has attempted to make accessible to the general reader all that is known about the Battle of Hastings and to present as detailed a reconstruction as is possible.  Furthermore, the author places the battle in the military context of eleventh-century Europe, painting a vivid picture of the combatants themselves—soldiery, cavalry, and their horses—as they struggled for victory. This is a book that any reader interested in England’s history will find indispensable.

    The few patrons who pass through his tavern are often travelers looking for a cold beer and warm bed, but they move on quickly after that. The pretty noblewoman who visits from time to time, owner of the land Lance works, barely notices him, despite his efforts. But what is a peasant to do?One night, a traveler, poor and weary, arrives with nary a coin in his pocket. Lance, ever a man of hospitality, allows him to stay. The weary traveler sleeps in one of the tavern rooms and dies overnight, leaving behind nothing except a book of spells. This spellbook, which talks, explains to Lance that this wizard had no next of kin and sought instead to grant his immense power to whoever took him in first. The spellbook now belongs to Lance, changing everything in an instant.Within the pages of the book are sigils—carefully scribed arcane markings that transfer power. By learning to replicate a sigil in the air, Lance is able to cast spells. Magic is relatively secretive in this world; there are no wizard schools, nor books to explain how it works. All wizards are sworn to secrecy. By gaining the power of the Sigilist, Lance’s opportunities become endless.Will Lance be able to use these spells wisely, helping the world he lives in? Can he use his power to win the heart of the fair noblewoman who has not once paid him any mind? Or will the strange powers that exist in the world lure him to serve the causes of a Sorcerer King who is slowly building his dominion to reign over the land?

    It presents historical perspectives on the development of nursing theory, assessments of concept and theory development and theory evaluation, middle-range theories, and shared theories from other disciplines in the sociologic, behavioral, and biomedical sciences, focusing on the application of theory.

    November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.

    It develops an understanding of function and evolution into the discussion of anatomy of the various systems.

    The myths have a way of entwining one with another, and it is difficult to present a coherent story line without feeling one has omitted the best part of the story. Inside you will read about... ✓ What Is A Myth? ✓ The Sources Of Greek Mythology ✓ The Creation Of The Universe And The Gods ✓ What Of Man? What Of Woman? ✓ The Greek Pantheon ✓ The Trojan War ✓ The Influence Of Greek Drama ✓ Two Greek Mortal Heroes In Mythological Tales This guide succeeds in presenting an overall sketch of the creation of the world and the battles that follow, resulting in Zeus taking his place as the supreme god and ruling the earth from Mount Olympus. It covers the creation of man, it seems, as a bit of an afterthought for the amusement of the Olympians and some of the most famous stories that have come down to us via the writings of the great dramatists of the Classical Age. There are concise biographies of the twelve gods that make up the Olympians as well as of the heroes of the Trojan War.

    The new edition from Chopra includes many topics encompassing the theory of structural dynamics and the application of this theory regarding earthquake analysis, response, and design of structures.
