Book Synopsis Circumference by : Nicholas Nicastro
Download or read book Circumference written by Nicholas Nicastro and published by St. Martin's Press. This book was released on 2008-11-25 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do you measure the size of the planet you're standing on? "Circumference" is the story of what happened when one man asked himself that very question. Nicholas Nicastro brings to life one of history's greatest experiments when an ancient Greek named Eratosthenes first accurately determined the distance around the spherical earth. In this fascinating narrative history, Nicastro takes a look at a deceptively simple but stunning achievement made by one man, millennia ago, with only the simplest of materials at his disposal. How was he able to measure the land at a time when distance was more a matter of a shrug and a guess at the time spent on a donkey's back? How could he be so confident in the assumptions that underlay his calculations: that the earth was round and the sun so far away that its rays struck the ground in parallel lines? Was it luck or pure scientific genius? Nicastro brings readers on a trip into a long-vanished world that prefigured modernity in many ways, where neither Eratosthenes' reputation, nor the validity of his method, nor his leadership of the Great Library of Alexandria were enough to convince all his contemporaries about the dimensions of the earth. Eratosthenes' results were debated for centuries until he was ultimately vindicated almost 2000 years later, during the great voyages of exploration. "Circumference" is a compelling scientific detective story that transports readers back to a time when humans had no idea how big their world was--and the fate of a man who dared to measure the incomprehensible.
Book Synopsis Eratosthenes' "Geography" by : Eratosthenes
Download or read book Eratosthenes' "Geography" written by Eratosthenes and published by Princeton University Press. This book was released on 2010-01-24 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first modern edition and first English translation of one of the earliest and most important works in the history of geography, the third-century Geographika of Eratosthenes. In this work, which for the first time described the geography of the entire inhabited world as it was then known, Eratosthenes of Kyrene (ca. 285-205 BC) invented the discipline of geography as we understand it. A polymath who served as librarian at Alexandria and tutor to the future King Ptolemy IV, Eratosthenes created the terminology of geography, probably including the word geographia itself. Building on his previous work, in which he determined the size and shape of the earth, Eratosthenes in the Geographika created a grid of parallels and meridians that linked together every place in the world: for the first time one could figure out the relationship and distance between remote localities, such as northwest Africa and the Caspian Sea. The Geographika also identified some four hundred places, more than ever before, from Thoule (probably Iceland) to Taprobane (Sri Lanka), and from well down the coast of Africa to Central Asia. This is the first collation of the more than 150 fragments of the Geographika in more than a century. Each fragment is accompanied by an English translation, a summary, and commentary. Duane W. Roller provides a rich background, including a history of the text and its reception, a biography of Eratosthenes, and a comprehensive account of ancient Greek geographical thought and of Eratosthenes' pioneering contribution to it. This edition also includes maps that show all of the known places named in the Geographika, appendixes, a bibliography, and indexes.

Book Synopsis America's Secret War by : George Friedman
Download or read book America's Secret War written by George Friedman and published by Anchor. This book was released on 2005-10-11 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: George Friedman delivers the geopolitical story that the mainstream media has been unable to uncover — the startling truth behind America’s foreign policy and war effort in Afghanistan, Iraq, and beyond. Friedman, founder of Stratfor, one of the world’s most respected private global intelligence firms, and Geopolitical Futures, has an unmatched ability to provide clear perspective on the current geopolitical map. In America's Secret War, George Friedman identifies the United States’ most dangerous enemies, delves into presidential strategies of the last quarter century, and reveals the real reasons behind the attack of 9/11—and the Bush administration’s motivation for the war in Iraq. It describes in eye-opening detail America’s covert and overt efforts in the global war against terrorism: Not only are U.S. armies in combat on every continent, but since 9/11 the intelligence services of dozens of nations have been operating in close partnership with the CIA. Drawing on his vast information-gathering network, Friedman presents an insightful picture of today’s world that goes far beyond what is reported on television and in other news media. Al Qaeda’s war plans and how they led to 9/11 The threat of a suitcase nuclear bomb in New York and how that changed the course of the war. The deal the U.S. made with Russia and Iran which made the invasion of Afghanistan possible – and how those deals affect the United States today. How fear and suspicion of the Saudis after 9-11 tore apart the Bush-Saudi relationship and why Saudi Arabia’s closest friends in the administration became the Saudi’s worst enemies. The real reasons behind George W. Bush’s invasion of Iraq and how WMD became the cover for a much deeper game. How the CIA miscalculated about Saddam Hussein’s and Iran’s real plans, leaving the U.S. bogged down in the war. How the war in Iraq began with a ruse, pretending that a “target of opportunity” attack on Saddam Hussein had presented itself. The real story about why the U.S. raises and lowers its alert status and why the United States can’t find and destroy al Qaeda. The strategic successes that are slowly leading the United States to victory America's Secret War is an unprecedented look at the new world war being waged behind-the-scenes today. It is sure to stir debate and capture headlines around the world.

Book Synopsis Below the Convergence by : Alan Gurney
Download or read book Below the Convergence written by Alan Gurney and published by W. W. Norton & Company. This book was released on 2007-02-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This wonderfully written book tells of the first Herculean expeditions to Antarctica, from astronomer Edmond Halley's 1699 voyage in the Paramore to the sealer John Balleny's 1839 excursion in the Eliza Scott, all in search of land, glory, fur, science, and profit. Life was harsh: crews had poor provisions and inadequate clothing, and scurvy was a constant threat. With unreliable--often homemade--charts, these intrepid explorers sailed in the stormy waters of the Southern Ocean below the Convergence, that sea frontier marking the boundary between the freezing Antarctic waters and the warmer sub-Antarctic seas. These men were the first to discover and exploit a new continent, which was not the verdant southern island they had imagined but an inhospitable expanse of rock and ice, ringed by pack ice and icebergs: Antarctica.
Book Synopsis The Catalogue of Shipwrecked Books by : Edward Wilson-Lee
Download or read book The Catalogue of Shipwrecked Books written by Edward Wilson-Lee and published by Scribner. This book was released on 2020-03-10 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This impeccably researched and “adventure-packed” (The Washington Post) account of the obsessive quest by Christopher Columbus’s son to create the greatest library in the world is “the stuff of Hollywood blockbusters” (NPR) and offers a vivid picture of Europe on the verge of becoming modern. At the peak of the Age of Exploration, Hernando Colón sailed with his father Christopher Columbus on his final voyage to the New World, a journey that ended in disaster, bloody mutiny, and shipwreck. After Columbus’s death in 1506, eighteen-year-old Hernando sought to continue—and surpass—his father’s campaign to explore the boundaries of the known world by building a library that would collect everything ever printed: a vast holding organized by summaries and catalogues; really, the first ever database for the exploding diversity of written matter as the printing press proliferated across Europe. Hernando traveled extensively and obsessively amassed his collection based on the groundbreaking conviction that a library of universal knowledge should include “all books, in all languages and on all subjects,” even material often dismissed: ballads, erotica, news pamphlets, almanacs, popular images, romances, fables. The loss of part of his collection to another maritime disaster in 1522, set off the final scramble to complete this sublime project, a race against time to realize a vision of near-impossible perfection. “Magnificent…a thrill on almost every page” (The New York Times Book Review), The Catalogue of Shipwrecked Books is a window into sixteenth-century Europe’s information revolution, and a reflection of the passion and intrigues that lie beneath our own insatiable desires to bring order to the world today.
