Wisdomkeepers of Stonehenge - The Living Libraries and Healers of Megalithic Culture (Paperback): Graham Phillips Wisdomkeepers of Stonehenge - The Living Libraries and Healers of Megalithic Culture (Paperback)

Reveals how Stonehenge was an extraordinary astronomical calendar used in the cultivation of ingredients for long-forgotten botanical cures Stonehenge is just one of thousands of stone circles erected throughout Britain and Ireland for over three millennia from 3,000 BC on. How did this building tradition survive for so long, over such a large area and with such complexity and uniformity, when the people of the British Isles lived in separate, isolated communities and left no evidence of a central leadership or obvious communication network? Graham Phillips argues that these stone circles are evidence of an astonishing system of healthcare and preservation of ancient medical knowledge that held together a society scattered across the British Isles. With stones aligned to the sun, moon, and certain stars, these ancient monuments enabled the precise timings necessary for the cultivation of medicinal plants. He explains how the megalithic priesthood possessed medical knowledge well beyond their time and may even have discovered a cure for cancer. Furthermore, because they had no form of writing, the megalithic people developed phenomenal memory techniques to preserve their knowledge over many generations, resulting in a class of wisdomkeepers that were not only healers but the living libraries of their culture. Drawing upon the latest discoveries from recent archaeological excavations and overlooked historical source material, Phillips reveals that the megalithic culture survived far longer than previously thought and that the people who held it together were an enigmatic shamanic sect ultimately called the Druids. Uncovering the secrets of ancient megalithic culture and the purpose of their enigmatic stone circles, Phillips contends that all the evidence has now been gathered to unlock the secrets encoded in the stones--and perhaps discover remedies for diseases still uncured by modern medicine today.

AN OBSERVER BOOK OF THE YEAR From the acclaimed author of The Information and Chaos, a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself. Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological - the electric telegraph, the steam railroad, the discovery of buried civilisations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture - from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

As seen in the major Netflix documentary `Mercury 13' In 1961, Wally Funk was among the Mercury 13, the first group of American pilots to pass the `Woman in Space' programme. Wally sailed through a series of rigorous physical and mental tests, with one of her scores beating all the male Mercury 7 astronauts', including John Glenn's, the first American in orbit. But just one week before the final phase of training, the programme was abruptly cancelled. A combination of politics and prejudice meant that none of the women ever flew into space. Undeterred, Wally went on to become America's first female aviation safety inspector, though her dream of being an astronaut never dimmed. In this offbeat odyssey, journalist and fellow space enthusiast Sue Nelson joins Wally, now approaching her eightieth birthday, as she races to make her own giant leap before it's too late. Covering their travels across the United States and Europe - taking in NASA's mission control in Houston, the European Space Agency's HQ in Paris and Spaceport America in New Mexico, where Wally's ride into space awaits - this is a uniquely intimate and entertaining portrait of a true aviation trailblazer.

David Christian, creator of Big History ('My favourite course of all time' Bill Gates), brings us the epic story of the universe and our place in it, from 13.8 billion years ago to the remote future 'Nails home the point: Life is a miracle ... A compelling history of everything' Washington Post 'Spectacular' Carlo Rovelli How did we get from the Big Bang to today's staggering complexity, in which seven billion humans are connected into networks powerful enough to transform the planet? And why, in comparison, are our closest primate relatives reduced to near-extinction? Big History creator David Christian gives the answers in a mind-expanding cosmological detective story told on the grandest possible scale. He traces how, during eight key thresholds, the right conditions have allowed new forms of complexity to arise, from stars to galaxies, Earth to homo sapiens, agriculture to fossil fuels.

It has been called the single most historic event of the 20th century: On July 20, 1969, Neil Armstrong, Buzz Aldrin, and Michael Collins met John F. Kennedy's call for a manned Moon landing by the end of the 1960s. A decade of tests and training, a staff of 400,000 engineers and scientists, a budget of billions, and the most powerful rocket ever launched all combined in an unprecedented event watched by millions the world over. And no one captured the men, the mood, and the machinery like Norman Mailer. One of the greatest writers of the 20th century, Norman Mailer was hired by LIFE magazine in 1969 to cover the Moon shot. He enhanced his reportage in the brilliantly crafted book, Of a Fire on the Moon, which is excerpted here. Equally adept at examining the science of space travel and the psychology of the people involved-from Saturn V rocket engineer Wernher von Braun to the crucial NASA support staff to the three astronauts-Mailer provides provocative and trenchant insights into this epoch-making event. Illustrating this volume are hundreds of photographs and maps from the NASA vaults, magazine archives, and private collections. These images document the development of the agency and the mission, life inside the command module and on the Moon's surface, and the world's jubilant reaction to the landing. This 50-year anniversary edition includes captions by leading Apollo 11 experts that explain the history and science behind the images, citing the mission log, publications of the day, and postflight astronaut interviews; while an evocative introduction by Colum McCann celebrates Mailer's incomparable skill at transforming "the science of space... the weight of history... the breadth of mythology" into prose.

Several Epoch of Reionization (EoR) experiments, for example, LOFAR, MWA and PAPER, are currently under way and producing results. These very deep observations not only set constraints on when and where the first sources formed in the early Universe and began (re)ionizing the predominantly neutral all-pervasive intergalactic medium, but they also provide high-quality data for cutting edge auxiliary foreground science. Obviously studying the physical origin of the foreground emission, whether Galactic or extragalactic, is a very exciting field in its own right and is of fundamental importance for perfecting the foreground removal techniques in the cosmological experiments. These proceedings of IAU S333 address both topics through giving the clearest and widest possible view on the EoR; presenting the state-of-the-art foreground science; and discussing challenges of upcoming and planned radio facilities such as HERA and SKA.

'Athena seized the writhing serpent and hurled it into the sky, and fixed it to the very pole of the heavens.' The constellations we recognize today were first mapped by the ancient Greeks, who arranged the stars into patterns for that purpose. In the third century BC Eratosthenes compiled a handbook of astral mythology in which the constellations were associated with figures from legend, and myths were provided to explain how each person, creature, or object came to be placed in the sky. Thus we can see Heracles killing the Dragon, and Perseus slaying the sea-monster to save Andromeda; Orion chases the seven maidens transformed by Zeus into the Pleiades, and Aries, the golden ram, is identified flying up to the heavens. This translation brings together the later summaries from Eratosthenes' lost handbook with a guide to astronomy compiled by Hyginus, librarian to Augustus. Together with Aratus's astronomical poem the Phaenomena, these texts provide a complete collection of Greek astral myths; imaginative and picturesque, they also offer an intriguing insight into ancient science and culture. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.

In this second English-language edition of one of his most notable works, Miguel Leon-Portilla explores the Maya Indians' remarkable concepts of time. At the book's first appearance Evon Z. Vogt, Curator of Middle American Ethnology in Harvard University, predicted that it would become "a classic in anthropology," a prediction borne out by the continuing critical attention given to it by leading scholars.

Like no other people in history, the ancient Maya were obsessed by the study of time. Their sages framed its cycles with tireless exactitude. Yet their preoccupation with time was not limited to calendrics; it was a central trait in their evolving culture.

In this absorbing work Leon-Portilla probes the question, What did time really mean for the ancient Maya in terms of their mythology, religious thought, worldview, and everyday life? In his analysis of key Maya texts and computations, he reveals one of the most elaborate attempts of the human mind to penetrate the secrets of existence.
