Sam Low, the author, has sailed with us on three voyages, written numerous articles and now, after ten years of work, has finished Hawaiki Rising. This book is an important part of our 'olelo, our history, and it contains the mana of all those who helped create and sail Hokule'a." Nainoa Thompson

    We all dance to these primary rhythms. This book reveals the poetic cosmology that lies within the cycles of the Sun and Moon as seen from the Earth.

    Is John Titor science fiction or science fact? After a world war in our future, John Titor claimed to have used a military time machine to travel from the year 2036. His story spans from 1975 where his mission was to obtain a computer system needed in his future. For mysterious reasons, instead of going home, he came forward to visit with his family and young self in 1998. From November of 2000 to March 2001, John spoke directly to numerous people on many Internet forums and chat rooms. In the posts, he discusses the future, the technology of time travel and his feelings about our society. Did he accurately predict the development of future physics, the reasons behind the Gulf War and the coming of mad cow disease to the U.S.? John Titor A Time Traveler's Tale, was compiled by John's mother in our time and bound in a 5.5 x 8.5 paperback protected by a laminated front and back cover. With 164 pages of text, the book also contains 9 pages of black and white photos John posted of his time machine and the operations manual that came with it!

    It has an algebra and trigonometry prerequisite, but calculus is preferred.

    One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today.This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the cosmological constant to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape.Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

    Ranging through the stars and the myths humans have told about them for millennia, Raymo delves into "a pilgrimage in quest of the soul of the night." Chet Raymo's elegant essays link the mysterious phenomena of the night sky with the human mind and spirit, as he ranges through the realms of mythology, literature, religion, history, and anthropology. Originally published two decades ago, The Soul of the Night is a classic work that is a must for those interested in the relationship between science and faith.

    Born of modest means in what is now Croatia and later becoming a naturalized American citizen, Tesla’s inventions include the alternating current (AC) that powers our homes today, radio, wireless transmission, X-rays, and the electrifying Tesla coil. He even worked on development of direct energy weapons (death rays) and vertical takeoff and landing (VTOL) aircraft. During his lifetime Tesla moved first to Paris, then to New York, and after a period of time in Colorado Springs back to New York City where he maintained two laboratories. Along the way he worked for Edison, then became his biggest rival, and formed friendships with such divergent personalities as George Westinghouse, Mark Twain, a pigeon, all while reflecting on a childhood cat. His idiosyncrasies included an obsession with numbers divisible by three, ardent gambling, and a near-pathological fear of germs. He rarely slept more than a few hours at a time, often going days without rest. While generally soft-spoken, he could be a consummate showman, often insisting that his Tesla coil be present while he lectured, seemingly shooting lightning bolts as he spoke. In the end he died alone and nearly penniless, having ceded perhaps billions of dollars in royalties to his friend George Westinghouse. This illustrated book takes us through Tesla’s life, his experiments and contributions to science, and brings us into his complex mind. Through ample use of his writings and interviews with the societies and inventors clubs that honor his name, we explore Tesla’s methods and discoveries, personality quirks, and his legacy for the modern world – both scientific and popular culture.

    . .The inspirational memoir of a former brickie who followed his passion for the stars and built his own observatory.Gary Fildes left school at sixteen, got a trade like most of his mates and was soon married with four kids. His life seemed set. But he had a secret. Something he only practised late at night with a few like-minded friends. Then one day, middle age approaching alarmingly, he acted on his lifelong passion. He finally came out. As an astronomer.Today, Gary is the founder and lead astronomer of Kielder Observatory, one of the top ten stargazing sites in the world, which he also helped to build. Situated in the beautiful forests of Kielder, Northumberland, within Europe’s largest protected dark sky park, it offers some of the UK's most spectacular views of stars, planets and galaxies.An Astronomer’s Tale is Gary’s inspirational story: part memoir, part nature writing, part seasonal guide to the night sky. It is a book brimming with passion; and at a time when the world is captivated by space, it will leave you ready to get out there and explore the wonders of the skies for yourself.

    All three astronauts were experienced pilots and had dreams of one day walking on the moon, but little did they know, nor did anyone else, that once they entered the spacecraft that cold winter day they would never leave it alive. The Apollo program would be perilously close to failure before it ever got off the ground. But rather than dooming the space program, this tragedy caused the spacecraft to be completely overhauled, creating a stellar flying machine to achieve the program’s primary goal: putting man on the moon. Apollo 1 is a candid portrayal of the astronauts, the disaster that killed them, and its aftermath. In it, readers will learn: How the Apollo 1 spacecraft was doomed from the start, with miles of uninsulated wiring and tons of flammable materials in a pure oxygen atmosphere, along with a hatch that wouldn’t open How, due to political pressure, the government contract to build the Apollo 1 craft went to a bidder with an inferior plan How public opinion polls were beginning to turn against the space control before the tragedy and got much worse after Apollo 1 is about America fulfilling its destiny of man setting foot on the moon. It’s also about the three American heroes who lost their lives in the tragedy, but whose lives were not lost in vain.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

    But with the unexpected death of her husband, her life became an empty, lightless space. Suddenly she was the single mother of two young boys, a widow at forty, clinging to three crumpled pages of instructions her husband had written for things like grocery shopping--things he had done while she did pioneering work as a planetary scientist at MIT. She became painfully conscious of her Asperger's, which before losing her husband had felt more like background noise. She felt, for the first time, alone in the universe.In this probing, invigoratingly honest memoir, Seager tells the story of how, as she stumblingly navigated the world of grief, she also kept looking for other worlds. She continues to develop groundbreaking projects, such as the Starshade, a sunflower-shaped instrument that, when launched into space, unfurls itself so as to block planet-obscuring starlight, and she takes solace in the alien beauty of exoplanets. At the same time, she discovers what feels every bit as wondrous: other people, reaching out across the space of her grief. Among them are the Widows of Concord, a group of women offering consolation and advice; and her beloved sons, Max and Alex. Most unexpected of all, there is another kind of one-in-a-billion match with an amateur astronomer.Equally attuned to the wonders of deep space and human connection, The Smallest Lights in the Universe is its own light in the dark.
