From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

    It repays us many times over to be good economists. Economic issues are active in our lives every day. However, when the subject of economics comes up in conversation or on the news, we can find ourselves longing for a more sophisticated understanding of the fundamentals of economics.36 lectures | 30 minutes each.

    Now Sobel brings her full talents to bear on what is perhaps her most ambitious topic to date-the planets of our solar system. Sobel explores the origins and oddities of the planets through the lens of popular culture, from astrology, mythology, and science fiction to art, music, poetry, biography, and history. Written in her characteristically graceful prose, The Planets is a stunningly original celebration of our solar system and offers a distinctive view of our place in the universe. * A New York Times extended bestseller * A Featured Alternate of the Book-of-the-Month Club, History Book Club, Scientific American Book Club, and Natural Science Book Club * Includes 11 full-color illustrations by artist Lynette R. Cook BACKCOVER: "[The Planets] lets us fall in love with the heavens all over again." -The New York Times Book Review "Playful . . . lyrical . . . a guided tour so imaginative that we forget we're being educated as we're being entertained." -Newsweek " [Sobel] has outdone her extraordinary talent for keeping readers enthralled. . . . Longitude and Galileo's Daughter were exciting enough, but The Planets has a charm of its own . . . . A splendid and enticing book." -San Francisco Chronicle "A sublime journey. [Sobel's] writing . . . is as bright as the sun and its thinking as star-studded as the cosmos." -The Atlanta Journal-Constitution "An incantatory serenade to the Solar System.

    What happened during those years and what has happened since to refine the understanding of this phenomenon is the fascinating story told here.We move from a coffee shop in Zurich, where Einstein and Max von Laue discuss the madness of quantum theory, to a bar in Brazil, as David Bohm and Richard Feynman chat over cervejas. We travel to the campuses of American universities—from J. Robert Oppenheimer’s Berkeley to the Princeton of Einstein and Bohm to Bell’s Stanford sabbatical—and we visit centers of European physics: Copenhagen, home to Bohr’s famous institute, and Munich, where Werner Heisenberg and Wolfgang Pauli picnic on cheese and heady discussions of electron orbits.Drawing on the papers, letters, and memoirs of the twentieth century’s greatest physicists, Louisa Gilder both humanizes and dramatizes the story by employing their own words in imagined face-to-face dialogues. Here are Bohr and Einstein clashing, and Heisenberg and Pauli deciding which mysteries to pursue. We see Schrödinger and Louis de Broglie pave the way for Bell, whose work is here given a long-overdue revisiting. And with his characteristic matter-of-fact eloquence, Richard Feynman challenges his contemporaries to make something of this entanglement.

    We wouldn’t have unraveled DNA or discovered Neptune or figured out how to put 5,000 songs in your pocket. Though many of us were scared away from this essential, engrossing subject in high school and college, Steven Strogatz’s brilliantly creative, down‑to‑earth history shows that calculus is not about complexity; it’s about simplicity. It harnesses an unreal number—infinity—to tackle real‑world problems, breaking them down into easier ones and then reassembling the answers into solutions that feel miraculous. Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves (a phenomenon predicted by calculus). Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes “backwards” sometimes; how to make electricity with magnets; how to ensure your rocket doesn’t miss the moon; how to turn the tide in the fight against AIDS. As Strogatz proves, calculus is truly the language of the universe. By unveiling the principles of that language, Infinite Powers makes us marvel at the world anew.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Yet in The Science of Interstellar, Kip Thorne, the physicist who assisted Nolan on the scientific aspects of Interstellar, shows us that the movie’s jaw-dropping events and stunning, never-before-attempted visuals are grounded in real science. Thorne shares his experiences working as the science adviser on the film and then moves on to the science itself. In chapters on wormholes, black holes, interstellar travel, and much more, Thorne’s scientific insights—many of them triggered during the actual scripting and shooting of Interstellar—describe the physical laws that govern our universe and the truly astounding phenomena that those laws make possible.Interstellar and all related characters and elements are trademarks of and © Warner Bros.

    The components of language are explained in easy-to-understand terms and the progression of the language from Germanic to Old, Middle, and Modern English is fully illustrated—including such revolutionary language upheavals as those brought about by the Norman Conquest and the Great Vowel Shift. One of the most interesting aspects of the English language lies in its variants, such as the “soda” vs. “pop” debate and the place of African-American English in modern culture. These and other dialectual curiosities are looked at in detail and placed in the context of today’s world. Finally, Professor Drout examines the future not only of the English language, but of all the world’s languages.

    Original, well researched, and well documented by distinguished sources, The Field is a book of hope and inspiration for today's world.

    Civilizations with the greatest strategists-often coupled with the greatest resources-have had a powerful edge over competing civilizations. From Napoleon's revolutionary campaigns to the way insurgency, terrorism, and nuclear weaponry have defined the nature of warfare in the 21st century, the results of military strategy have changed the course of history. Masters of War: History's Greatest Strategic Thinkers gives you an inside look at both the content and historical context of the world's greatest war strategists. Taught by Professor Andrew R. Wilson-and modeled on his elite course at the United States Naval War College-these 24 lectures will change the way you read newspaper headlines by instilling in you a new appreciation for the subtleties and complexities of strategy-and how nations and military leaders have adapted to the dynamic realm of fog, friction, and chance. See how George Washington adapted his strategy after losing New York during the American Revolution. Learn why FDR went against the advice of Chief of Staff George Marshall and embarked on a campaign in north Africa in the summer of 1942. Trace the United States' Pacific strategy, from War Plan Dog to Guadalcanal to the island-hopping campaign. Apply Clausewitz's "culminating point of victory" to the Persian Gulf War. Consider the strategy behind recent U. N. airstrikes in Libya. The great masters of war have been writing about strategy for thousands of years, and understanding their works can help a nation achieve military and political success.

    This era shook the foundations of the old world and marked a permanent shift for politics, religion, and society - not just for France, but for all of Europe. An account of the events alone reads like something out of a thrilling novel: France’s oppressed and hungry masses rise up against their government. In Paris, crowds storm the Bastille looking for bread and weaponry. Rumors, panic, and fear grip the nation as it faces an uncertain future. The National Assembly adopts the Declaration of the Rights of Man, the first bold step toward the invention of democratic politics and a republican state. A young Corsican named Napoleon Bonaparte stuns Europe with his military strategy and political boldness.Living the French Revolution and the Age of Napoleon is your opportunity to learn the full story of this captivating period. Taught by Dr. Suzanne M. Desan, these 48 exciting lectures give you a broad and comprehensive survey of one of the most important eras in modern history.Disclaimer: Please note that this recording may include references to supplemental texts or print references that are not essential to the program and not supplied with your purchase.©2013 The Teaching Company, LLC (P)2013 The Great Courses

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious. And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.
