He gives a fantastic overview of the teachings of that man. Hall covers his theories of transmigration, symmetrical solids, aphorisms, astronomy, and many other things, as well as what he expected of his students and accounts of his school and initiations.

They never knew how he did it. Few composers write more than one or two symphonies in their lifetimes. Beethoven spent a year on his shorter symphonies but more than six years on his 9th Symphony. The prodigy Mozart finished his last three symphonies (39, 40, and 41) in the span of a few weeks. His 25th Symphony took only two days.

They have always scared him in the past - the Rangers, with their dark cloaks and shadowy ways. The villagers believe the Rangers practice magic that makes them invisible to ordinary people. And now 15-year-old Will, always small for his age, has been chosen as a Ranger's apprentice. What he doesn't yet realize is that the Rangers are the protectors of the kingdom. Highly trained in the skills of battle and surveillance, they fight the battles before the battles reach the people. And as Will is about to learn, there is a large battle brewing.

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. 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 turn the tide in the fight against AIDS.

Homer’s Iliad and Odyssey are unquestionably two of the greatest epic masterpieces in Western literature. Though more than 2,700 years old, their stories of brave heroics, capricious gods, and towering human emotions are vividly timeless. The Iliad can justly be called the world’s greatest war epic. The terrible and long-drawn-out siege of Troy remains one of the classic campaigns. The Odyssey chronicles the many trials and adventures Odysseus must pass through on his long journey home from the Trojan wars to his beloved wife.

This is the first volume in a bold new series that tells the stories of all peoples, connecting historical events from Europe to the Middle East to the far coast of China, while still giving weight to the characteristics of each country. Susan Wise Bauer provides both sweeping scope and vivid attention to the individual lives that give flesh to abstract assertions about human history. This narrative history employs the methods of "history from beneath" - literature, epic traditions, private letters, and accounts - to connect kings and leaders with the lives of those they ruled.

For more than 1,000 years, Christians and Muslims lived side by side, sometimes at peace and sometimes at war. When Christian armies seized Jerusalem in 1099, they began the most notorious period of conflict between the two religions. Depending on who you ask, the fall of the holy city was either an inspiring legend or the greatest of horrors. In Crusaders, Dan Jones interrogates the many sides of the larger story, charting a deeply human and avowedly pluralist path through the crusading era.

Popular Lost Cities author David Hatcher Childress takes us into the amazing world of ancient technology, from computers in antiquity to the flying machines of the gods. Childress looks at the technology that was allegedly used in Atlantis and the theory that the Great Pyramid of Egypt was originally a gigantic power station. He examines tales of ancient flight and the technology that it involved; how the ancients used electricity; megalithic building techniques; the use of crystal lenses and the fire from the gods; and more.

In 1714, England's Parliament offered a huge reward to anyone whose method of measuring longitude could be proven successful. The scientific establishment--from Galileo to Sir Isaac Newton--had mapped the heavens in its certainty of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution--a clock that would keep precise time at sea, something no clock had been able to do on land. And the race was on....

The Arabic legacy of science and philosophy has long been hidden from the West. British-Iraqi physicist Jim Al-Khalili unveils that legacy to fascinating effect by returning to its roots in the hubs of Arab innovation that would advance science and jump-start the European Renaissance.

Founded by Alexander the Great and built by self-styled Greek pharaohs, the city of Alexandria at its height dwarfed both Athens and Rome. It was the marvel of its age, legendary for its vast palaces, safe harbors, and magnificent lighthouse. But it was most famous for the astonishing intellectual efflorescence it fostered and the library it produced. If the European Renaissance was the "rebirth" of Western culture, then Alexandria, Egypt, was its birthplace.

In this fascinating history spanning continents and centuries, historian David Wootton offers a lively defense of science, revealing why the Scientific Revolution was truly the greatest event in our history. The Invention of Science goes back 500 years in time to chronicle this crucial transformation, exploring the factors that led to its birth and the people who made it happen. Wootton argues that the Scientific Revolution was actually five separate yet concurrent events that developed independently.

Why didn't the Chinese discover America? Why were people so slow to learn the earth goes around the sun? How and why did we begin to think of "species" of plants and animals? How, when, and why did people begin digging in the earth to learn about the past? How did the study of economics begin? These are but a few of the fascinating questions answered by Dr. Boorstin, Librarian of Congress Emeritus.

"Something here really stinks to high heaven," writes Erich von Däniken. "In Twilight of the Gods," says von Däniken, "I document precisely what it was that left the first visitors breathless as they stood before the mighty stone blocks some 400 years ago. I will show you what archeologists discovered hundreds of years ago and demonstrate how much has been destroyed over the centuries. Intentionally.

James Gleick has long been fascinated by the making of science: how ideas order visible appearances, how equations can give meaning to molecular and stellar phenomena, how theories can transform what we see. In Chaos, he chronicled the emergence of a new way of looking at dynamic systems; in Genius, he portrayed the wondrous dimensions of Richard Feymnan's mind.

If you were taught that the Middle Ages were a time of intellectual stagnation, superstition, and ignorance, you were taught a myth that has been utterly refuted by modern scholarship. As a physicist and historian of science James Hannam shows in his brilliant new book, The Genesis of Science: How the Christian Middle Ages Launched the Scientific Revolution, without the scholarship of the "barbaric" Middle Ages, modern science simply would not exist. The Middle Ages were a time of one intellectual triumph after another.

The Clockwork Universe is the story of a band of men who lived in a world of dirt and disease but pictured a universe that ran like a perfect machine. A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with natures most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.

Like the alphabet, the calendar, or the zodiac, the periodic table of the chemical elements has a permanent place in our imagination. But aside from the handful of common ones (iron, carbon, copper, gold), the elements themselves remain wrapped in mystery. We do not know what most of them look like, how they exist in nature, how they got their names, or of what use they are to us.

Throughout history, thinkers from mathematicians to theologians have pondered the mysterious relationship between numbers and the nature of reality. In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887.... This curious mathematical relationship, widely known as "The Golden Ratio", was discovered by Euclid more than 2,000 years ago. Since then it has shown a propensity to appear in the most astonishing variety of places.

New York Times bestselling historian Gavin Menzies presents newly uncovered evidence revealing, conclusively, that “the lost city of Atlantis” was not only real but also at the heart of a highly advanced global empire that reached the shores of America before being violently wiped from the earth. For three millennia, the legend of Atlantis has gripped the imaginations of explorers, philosophers, occultists, treasure hunters, historians, and archaeologists. Until now, it has remained shrouded in myth. Yet, like ancient Troy, is it possible that this fabled city actually existed?
