Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity--dark energy--is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking--one that may change forever our notions of where the Universe came from and where it is going.

    He went on to become a twentieth-century icon-a man whose name and face are synonymous with "genius." Now, at last, ordinary readers can explore Einstein's life and work in this new For Dummies guide. Physicist Carlos Calle chronicles Einstein's career and explains his work-including the theories of special and general relativity-in language that anyone can understand.

And he shows how Einstein's work continues to affect our world today, from nuclear power to space travel to artificial intelligence.

    The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was celebrated around the world.And yet, virtually no one who read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you understand the details, this story ranks as one of the most thrilling in the history of modern science.Award-winning theoretical physicist Sean Carroll, a brilliant researcher as well as a gifted speaker who excels in explaining scientific concepts to the public, is perfectly positioned to tell this story. In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.You also get an in-depth view of the Large Hadron Collider - the largest machine ever built, and the device responsible for finally revealing the concept of the Higgs boson as reality. By the end, you'll understand how the Higgs boson verifies the final piece in the Standard Model of particle physics, and how its discovery validates and deepens our understanding of the universe.

    Applying the same objective criteria to legal and illegal substances, an argument is made that legality is not a clear measure for harm. Tackling a variety of questions, such as Which is more harmful—Ecstasy or alcohol? Can addiction be cured? and Does the "War on Drugs" have serious unintended effects that can hurt children?, this analysis equips readers with the ability to make educated decisions regarding drugs both personally and in their communities. Broadening the scope of the discussion, a framework is explored for formulating national drug policies that will minimize a myriad of harms—social, medical, criminal, financial, and environmental.

    For mathematicians, physicists, engineers, and everyone else with an interest in mathematics' cutting edge, The Millennium Problems is the definitive account of a subject that will have a very long shelf life.

    Hungarian-born Erdős believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century's leading number theorist and the most prolific mathematician who ever lived. Erdős's important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers. Witty and filled with the sort of mathematical puzzles that intrigued Erdős and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.

    QFT is the only physics theory that makes sense and that dispels or resolves the paradoxes of relativity and quantum mechanics that have confused and mystified so many people.

    Most amateurs possess erroneous thinking processes that remain with them throughout their chess lives. These flaws in their mental armour result in stinging defeats and painful reversals. Books can be bought and studied, lessons can be taken -- but in the end, these elusive problems always prove to be extremely difficult to eradicate. Seeking a solution to this dilemma, the author wrote down the thoughts of his students while they played actual games, analysed them, and catalogued the most common misconceptions that arose. This second edition greatly expands on the information contained in the popular first edition.

    Today, scientists are attempting to measure the entire universe and to determine its origin. Although the methods have changed, the quest to chart the horizons of space and time continues to be one of the great adventures of science.Measuring the Universe is an eloquent chronicle of the men and women– from Aristarchus to Cassini, Sir Isaac Newton to Henrietta Leavitt and Stephen Hawking–who have gradually unlocked the mysteries of "how far" and in so doing have changed our ideas about the size and nature of the universe and our place in it. Kitty Ferguson reveals their methods to have been as inventive as their results were–and are–eye-opening. Advances such as Copernicus's revolutionary insights about the arrangement of the solar system, William Herschel's meticulous creation of the first three-dimensional map of the universe, and Edwin Hubble's astonishing discovery that the universe is expanding have by turns revolutionized our concept of the universe. Connecting centuries of breakthroughs with the political and cultural events surrounding them, Ferguson makes astronomy part of the sweep of history.To measure the seemingly immeasurable, scientists have always pushed the boundaries of the imagination–today, for example, facing the paradox of an ever-expanding universe that doesn't appear to expand into anything. In Kitty Fergeson's skillfill hands, the unimaginable becomes accessible and the splendid quest something we all can share.

    . . . [He] takes us on a lively tour of engineers, their creations and their necessary turns of mind."   --Los Angeles TimesFrom the Ferris wheel to the integrated circuit, feats of engineering have changed our environment in countless ways, big and small. In Remaking the World: Adventures in Engineering, Duke University's Henry Petroski focuses on the big: Malaysia's 1,482-foot Petronas Towers as well as the Panama Canal, a cut through the continental divide that required the excavation of 311 million cubic yards of earth.        Remaking the World tells the stories behind the man-made wonders of the world, from squabbles over the naming of the Hoover Dam to the effects the Titanic disaster had on the engineering community of 1912. Here, too, are the stories of the personalities behind the wonders, from the jaunty Isambard Kingdom Brunel, designer of nineteenth-century transatlantic steamships, to Charles Steinmetz, oddball genius of the General Electric Company, whose office of preference was a battered twelve-foot canoe. Spirited and absorbing, Remaking the World is a celebration of the creative instinct and of the men and women whose inspirations have immeasurably improved our world."Petroski [is] America's poet laureate of technology. . . . Remaking the World is another fine book."   --Houston Chronicle"Remaking the World really is an adventure in engineering."--San Diego Union-Tribune

    But a dispute over its discovery sowed the seeds of discontent between two of the greatest scientific giants of all time - Sir Isaac Newton and Gottfried Wilhelm Leibniz." "Today Newton and Leibniz are generally considered the twin independent inventors of calculus. They are both credited with giving mathematics its greatest push forward since the time of the Greeks. Had they known each other under different circumstances, they might have been friends. But in their own lifetimes, the joint glory of calculus was not enough for either and each declared war against the other, openly and in secret." This long and bitter dispute has been swept under the carpet by historians - perhaps because it reveals Newton and Leibniz in their worst light - but The Calculus Wars tells the full story in narrative form for the first time. This history ultimately exposes how these twin mathematical giants were brilliant, proud, at times mad, and in the end completely human.

       With honed sensitivity and unquestioned expertise, Stuart Isacoff—pianist, critic, teacher, and author of Temperament: How Music Became a Battleground for the Great Minds of Western Civilization—unfolds the ongoing history and evolution of the piano and all its myriad wonders: how its very sound provides the basis for emotional expression and individual style, and why it has so powerfully entertained generation upon generation of listeners. He illuminates the groundbreaking music of Mozart, Beethoven, Liszt, Schumann, and Debussy. He analyzes the breathtaking techniques of Glenn Gould, Oscar Peterson, Vladimir Ashkenazy, Arthur Rubinstein, and Van Cliburn, and he gives musicians including Alfred Brendel, Murray Perahia, Menahem Pressler, and Vladimir Horowitz the opportunity to discuss their approaches. Isacoff delineates how classical music and jazz influenced each other as the uniquely American art form progressed from ragtime, novelty, stride, boogie, bebop, and beyond, through Scott Joplin, Fats Waller, Duke Ellington, Bill Evans, Thelonious Monk, Chick Corea, Herbie Hancock, Cecil Taylor, and Bill Charlap. A Natural History of the Piano distills a lifetime of research and passion into one brilliant narrative. We witness Mozart unveiling his monumental concertos in Vienna’s coffeehouses, using a special piano with one keyboard for the hands and another for the feet; European virtuoso Henri Herz entertaining rowdy miners during the California gold rush; Beethoven at his piano, conjuring healing angels to console a grieving mother who had lost her child; Liszt fainting in the arms of a page turner to spark an entire hall into hysterics. Here is the instrument in all its complexity and beauty. We learn of the incredible craftsmanship of a modern Steinway, the peculiarity of specialty pianos built for the Victorian household, the continuing innovation in keyboards including electronic ones. And most of all, we hear the music of the masters, from centuries ago and in our own age, brilliantly evoked and as marvelous as its most recent performance.   With this wide-ranging volume, Isacoff gives us a must-have for music lovers, pianists, and the armchair musician.

    In addition, the controlability of power flows in the power grid has added a new dimension on the use of HVDC links in the context of developing Smart Grids. The power transfer from off-shore wind generation is another new application.
