Book Description
The Antikythera Mechanism, now 82 small fragments of corroded bronze, was an ancient Greek machine simulating the cosmos as the Greeks understood it. Reflecting the most recent researches, A Portable Cosmos presents it as a gateway to Greek astronomy and technology and their place in Greco-Roman society and thought.

Book Description
In Antikythera Mechanism: The Story Behind the Genius of the Greek Computer and Its Demise, Evaggelos Vallianatos, historian and ecopolitical theorist, shows that after the conquest of Persia by Alexander the Great in the late fourth century BCE, the Greeks, especially in Egypt, reached unprecedented heights of achievements in science, technology, and civilization. The Antikythera Mechanism, an astronomical computer probably crafted in Rhodes in the second century BCE, was proof of that prowess. It’s the grandfather of our computers. Greek sponge divers discovered the Antikythera Mechanism in 1900 on a 2,100-year-old Roman-era shipwreck. The hand-powered device reveals a sophisticated Greek technology previously unknown to scholars and historians, not seen and understood again until the twentieth and twenty-first centuries. The book not only describes how the sophisticated political and technological infrastructure of the Greeks after Alexander the Great resulted in the Antikythera celestial computer, and the bedrock of science and technology we know today, but also how the influence of Christianity on Greek civilization destroyed the nascent computer age of ancient Greece. Vallianatos, born in Greece and educated in America, is a historian, author, and journalist. He is a passionate champion of Greek culture and a well-suited guide to this historical account. Vallianatos explains how and why Greek scientists employed advanced engineering in translating the beautiful conception of the Antikythera Mechanism into an astronomical computer of genius: a bronze-geared device of mathematical astronomy, predicting the eclipses of the Sun and the Moon; calculating the risings and settings of important stars and constellations, and the movements of the planets around the Sun; while mechanizing the predictions of scientific theories. The computer’s accurate calendar connected these cosmic phenomena to the Olympics and other major Panhellenic religious and athletic celebrations, bringing the Greeks closer to their gods, traditions, and the Cosmos.

Book Description
In 1900 a group of sponge divers blown off course in the Mediterranean discovered an Ancient Greek shipwreck near the island of Antikythera dating from around 70 BC. Lying unnoticed for months amongst their hard-won haul was what appeared to be a formless lump of corroded rock, which turned out to be the most stunning scientific artefact we have from antiquity. For more than a century this 'Antikythera mechanism' - an ancient computer - puzzled academics, but now, more than 2000 years after the device was lost at sea, scientists have pieced together its intricate workings. In Decoding the Heavens, Jo Marchant tells for the first time the story of the 100-year quest to understand the Antikythera mechanism. Along the way she unearths a diverse cast of remarkable characters - ranging from Archimedes to Jacques Cousteau - and explores the deep roots of modern technology not only in Ancient Greece, the Islamic world and medieval Europe.

Book Description
*Includes pictures *Chronicles the discovery and theories over the mechanism's origins and capabilities *Includes footnotes, online resources and a bibliography for further reading. *Includes a table of contents "It multiplies, divides and subtracts, but you can't program it." - Michael Edmunds Discovering ancient shipwrecks hasn't been a novelty for thousands of years, but when artifacts were salvaged from a Roman shipwreck off the Greek island of Antikythera in 1900, the discovery of one set off one of the great mysteries of antiquity. When sponge divers investigated the shipwreck, they found the kind of items often associated with such discoveries, including marble statues, pottery, jewelry, and coins, but they also discovered a strange object, the likes of which nobody had ever seen before. Initially assumed to be pieces of rock, it turned out that the item, soon to be dubbed the Antikythera mechanism, consisted of dozens of pieces, many of which had gears. In fact, while scholars quickly deduced that it had an astronomical purpose, many believed the mechanism was too advanced to actually date back to antiquity. As it turned out, of course, the Antikythera mechanism did date back to the 1st or 2nd century BCE, and as scholars began to more fully comprehend its abilities, fascination over the device grew. In conjunction with the determination that the mechanism was an analog computer of sorts that could predict astronomical phenomena like the positions of stars and eclipses, conjecture over the origins of the device led to theories over what the Romans were going to do with it, and whether the device was created by the Greek genius Archimedes himself. To this day, debate continues over whether there were predecessors to the model, where the astronomical observations that went into creating the model were taken, and whether the ultimate origins of the device might even be Babylonian. The Antikythera Mechanism: The History and Mystery of the Ancient World's Most Famous Astronomical Device chronicles the discovery and study of the famous device. Along with pictures of important people, places, and events, you will learn about the Antikythera mechanism like never before, in no time at all.

Book Description
Hannah Holmes A mesmerizing expedition around our dusty world Some see dust as dull and useless stuff. But in the hands of author Hannah Holmes, it becomes a dazzling and mysterious force; Dust, we discover, built the planet we walk upon. And it tinkers with the weather and spices the air we breathe. Billions of tons of it rise annually into the air--the dust of deserts and forgotten kings mixing with volcanic ash, sea salt, leaf fragments, scales from butterfly wings, shreds of T-shirts, and fireplace soot. Eventually, though, all this dust must settle. The story of restless dust begins among exploding stars, then treks through the dinosaur beds of the Gobi Desert, drills into Antarctic glaciers, filters living dusts from the wind, and probes the dark underbelly of the living-room couch. Along the way, Holmes introduces a delightful cast of characters--the scientists who study dust. Some investigate its dark side: how it killed off dinosaurs and how its industrial descendents are killing us today. Others sample the shower of Saharan dust that nourishes Caribbean jungles, or venture into the microscopic jungle of the bedroom carpet. Like The Secret Life of Dust, however, all of them unveil the mayhem and magic wrought by little things. Hannah Holmes (Portland, ME) is a science and natural history writer for the Discovery Channel Online. Her freelance work has been widely published, appearing in the Los Angeles Times Magazine, the New York Times Magazine, Outside, Sierra, National Geographic Traveler, and Escape. Her broadcast work has been featured on Living on Earth and the Discovery Channel Online's Science Live.
