The first popular book to explain the dramatic theory behind the Moon's genesis This lively science history relates one of the great recent breakthroughs in planetary astronomy-a successful theory of the birth of the Moon. Science journalist Dana Mackenzie traces the evolution of this theory, one little known outside the scientific community: a Mars-sized object collided with Earth some four billion years ago, and the remains of this colossal explosion-the Big Splat-came together to form the Moon. Beginning with notions of the Moon in ancient cosmologies, Mackenzie relates the fascinating history of lunar speculation, moving from Galileo and Kepler to George Darwin (son of Charles) and the Apollo astronauts, whose trips to the lunar surface helped solve one of the most enigmatic mysteries of the night sky: who hung the Moon? Dana Mackenzie (Santa Cruz, CA) is a freelance science journalist. His articles have appeared in such magazines as Science, Discover, American Scientist, The Sciences, and New Scientist.

The Moon is not a cold, dead rock but a rich, fascinating world just as alive as Earth • Investigates the Moon as the home of an alien intelligence who controls humanity • Examines several of NASA’s Apollo missions and the findings they concealed • Reveals the many holes in the “Giant Impact” theory about the Moon’s origins and the evidence for a hollow, artificial Moon • Explores the deep influence of the Moon on the collective mind of humanity and occult teachings about the Moon from the Qabbalah, tarot, and other sources Despite being the most prominent celestial body after the Sun, the Moon has many qualities that science has yet to explain. Lunar rock samples reveal the Moon once had a magnetic field like the Earth, and seismic experiments by NASA suggest the Moon is at least partially hollow. For centuries people have observed lights, moving clouds and shadows, and even the disappearance of entire craters via telescope. Apollo astronauts repeatedly felt the presence of a “non-human intelligence” during their Moon visits, and many indigenous traditions speak of malevolent visitors from the Moon. A growing body of astrophysical and geological evidence shows the Moon is not an entirely natural world--that someone or something altered it long ago. Louis Proud explores the phases and movements of the Moon along with its ancient and mysterious features--its craters, maria, rilles, tunnels, and domes. He examines several of NASA’s Apollo missions, showing not that NASA faked the Moon expeditions but that they concealed what the astronauts found there. He explains the many holes in the commonly accepted “Giant Impact” theory of the Moon’s origins and reveals the evidence for a hollow, artificial Moon placed in orbit eons ago to observe Earth. Examining the deep influence of the Moon on the collective mind of humanity, Proud looks at what the Qabbalah, the tarot, and other occult traditions say about the Moon and interprets G. I. Gurdjieff’s teachings that “we are food for the Moon.” He investigates the Moon as a gateway to another realm, as the Purgatory of Christianity, and as the home of an alien intelligence who controls and exploits humanity. Examining the Moon from both scientific and esoteric perspectives, Proud shows the Moon is not a cold, dead rock but a rich, fascinating world just as alive as Earth.

A Turing Award-winning computer scientist and statistician shows how understanding causality has revolutionized science and will revolutionize artificial intelligence "Correlation is not causation." This mantra, chanted by scientists for more than a century, has led to a virtual prohibition on causal talk. Today, that taboo is dead. The causal revolution, instigated by Judea Pearl and his colleagues, has cut through a century of confusion and established causality--the study of cause and effect--on a firm scientific basis. His work explains how we can know easy things, like whether it was rain or a sprinkler that made a sidewalk wet; and how to answer hard questions, like whether a drug cured an illness. Pearl's work enables us to know not just whether one thing causes another: it lets us explore the world that is and the worlds that could have been. It shows us the essence of human thought and key to artificial intelligence. Anyone who wants to understand either needs The Book of Why.

This book tells the story of Apollo 11 and dispels the myth that NASA faked the moon landings. The story is brought to life by exploiting the flight plan, mission report, in-flight transcripts (including conversations among the crew in the spacecraft that were not transmitted) and post-flight debriefing. It features scans recently produced by NASA of the original Hasselblad film. The final chapters discuss what was learned of the moon rocks, and reviews the follow-on missions. The author’s impressive expertise and knowledge of the Moon landings shines through and seamlessly unites the myriad details of the mission.

A determined child goes the extra mile to try to cheer the lonely half moon Have you ever looked up at the half-moon hiding in the night sky and thought it looked just the littlest bit lonely without its other half? Imagine . . . having no one to glow with no one to play with no one to share how much you like puppies and big, fuzzy bears. If you’re like this determined young child, you might stay up every night to keep the moon company. Maybe if you share your treats and toys and stories, you’ll cheer him up. But the moon is very shy, so it might take some time. Still, if you’re very very patient, you just might make a new friend. From the Hardcover edition.

Over the course of the twentieth century, scientists came to accept four counterintuitive yet fundamental facts about the Earth: deep time, continental drift, meteorite impact, and global warming. When first suggested, each proposition violated scientific orthodoxy and was quickly denounced as scientific—and sometimes religious—heresy. Nevertheless, after decades of rejection, scientists came to accept each theory. The stories behind these four discoveries reflect more than the fascinating push and pull of scientific work. They reveal the provocative nature of science and how it raises profound and sometimes uncomfortable truths as it advances. For example, counter to common sense, the Earth and the solar system are older than all of human existence; the interactions among the moving plates and the continents they carry account for nearly all of the Earth's surface features; and nearly every important feature of our solar system results from the chance collision of objects in space. Most surprising of all, we humans have altered the climate of an entire planet and now threaten the future of civilization. This absorbing scientific history is the only book to describe the evolution of these four ideas from heresy to truth, showing how science works in practice and how it inevitably corrects the mistakes of its practitioners. Scientists can be wrong, but they do not stay wrong. In the process, astonishing ideas are born, tested, and over time take root.

Most popular books about science, and even about mathematics, tiptoe around equations as if they were something to be hidden from the reader's tender eyes. Dana Mackenzie starts from the opposite premise: He celebrates equations. No history of art would be complete without pictures. Why, then, should a history of mathematics--the universal language of science--keep the masterpieces of the subject hidden behind a veil? The Universe in Zero Words tells the history of twenty-four great and beautiful equations that have shaped mathematics, science, and society--from the elementary (1+1=2) to the sophisticated (the Black-Scholes formula for financial derivatives), and from the famous (E=mc2) to the arcane (Hamilton's quaternion equations). Mackenzie, who has been called "a popular-science ace" by Booklist magazine, lucidly explains what each equation means, who discovered it (and how), and how it has affected our lives. Illustrated in color throughout, the book tells the human and often-surprising stories behind the invention or discovery of the equations, from how a bad cigar changed the course of quantum mechanics to why whales (if they could communicate with us) would teach us a totally different concept of geometry. At the same time, the book shows why these equations have something timeless to say about the universe, and how they do it with an economy (zero words) that no other form of human expression can match. The Universe in Zero Words is the ultimate introduction and guide to equations that have changed the world.
