Discusses the relationship between the earth and the sun.
In this original, wide-ranging, and endlessly thought-provoking work of popular nonfiction, a leading science writer uncovers the pervasive presence of shadows in our world. For Plato, shadows were the symbol of our limitations. For Galileo, they knocked the Earth from the center of the cosmos. They are a source of fear and a symbol of ignorance, and they loom large in art and design, mythology and folklore, physics and metaphysics, and architecture and urban planning. From shadows puppets and the psychology of shadows to the role of shadows in astronomy and the influence of shadows on the architectural profiles of our cities, Roberto Casati awakens our fascination in this tour-de-force of investigation and imagination.
Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.
We live in a world of optical marvels - from the commonplace but beautiful rainbow, to the rare and eerie superior mirage. But how many of us really understand how a rainbow is formed, why the setting sun is red and flattened, or even why the sky at night is not absolutely black? This beautiful and informative guide provides clear explanations to all naturally occurring optical phenomena seen with the naked eye, including shadows, halos, water optics, mirages and a host of other spectacles. Separating myth from reality, it outlines the basic principles involved, and supports them with many figures and references. A wealth of rare and spectacular photographs, many in full color, illustrate the phenomena throughout. In this new edition of the highly-acclaimed guide to seeing, photographing and understanding nature's optical delights, the authors have added over 50 new images and provided new material on experiments you can try yourself.
With beautiful illustrations and a detailed map, Sun Moon Earth has everything you need to get ready for the next solar eclipse. On April 8, 2024, millions of Americans will experience an awe-inspiring phenomenon: a total eclipse of the sun. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events. Greek philosophers discovered eclipses' cause and used them to measure their world and the cosmos beyond. Victorian-era scientists mounted eclipse expeditions during the age of globe-spanning empires. And modern-day physicists continue to use eclipses to confirm Einstein's theory of relativity. Beautifully illustrated and lyrically written, Sun Moon Earth is the ideal guide for all eclipse watchers and star gazers alike.
In the tradition of Iron and Silk and Touch the Dragon, Jamie Zeppa’s memoir of her years in Bhutan is the story of a young woman’s self-discovery in a foreign land. It is also the exciting début of a new voice in travel writing. When she left for the Himalayan kingdom of Bhutan in 1988, Zeppa was committing herself to two years of teaching and a daunting new experience. A week on a Caribbean beach had been her only previous trip outside Canada; Bhutan was on the other side of the world, one of the most isolated countries in the world known as the last Shangri-La, where little had changed in centuries and visits by foreigners were restricted. Clinging to her bags full of chocolate, hair conditioner and Immodium, she began the biggest challenge of her life, with no idea she would fall in love with the country and with a Bhutanese man, end up spending nine years in Bhutan, and begin a literary career with her account of this transformative journey. At her first posting in a remote village of eastern Bhutan, she is plunged into an overwhelmingly different culture with squalid Third World conditions and an impossible language. Her house has rats and fleas and she refuses to eat the local food, fearing the rampant deadly infections her overly protective grandfather warned her about. Gradually, however, her fear vanishes. She adjusts, begins to laugh, and is captivated by the pristine mountain scenery and the kind students in her grade 2 class. She also begins to discover for herself the spiritual serenity of Buddhism. A transfer to the government college of Sherubtse, where the housing conditions are comparatively luxurious and the students closer to her own age, gives her a deeper awareness of Bhutan’s challenges: the lack of personal privacy, the pressure to conform, and the political tensions. However, her connection to Bhutan intensifies when she falls in love with a student, Tshewang, and finds herself pregnant. After a brief sojourn in Canada to give birth to her son, Pema Dorji, she marries Tshewang and makes Bhutan her home for another four years. Zeppa’s personal essay about her culture shock on arriving in Bhutan won the 1996 CBC/Saturday Night literary competition and appeared in the magazine. She flew home to accept the prize, where people encouraged her to pursue her writing. Her letters from Bhutan also featured on CBC’s Morningside. The book that grew out of this has been published in Canada and the United States to ecstatic reviews, followed by British, German, Dutch, Italian and Spanish editions. Although cultural differences finally separated Jamie and Tshewang in 1997 while she was writing the book and she returned to Canada, she will always feel at home in Bhutan. Zeppa shares her compelling insights into this land and culture, but Beyond the Sky and the Earth is more than a travel book. With rich, spellbinding prose and bright humour, it describes a personal journey in which Zeppa acquires a deeper understanding of what it means to leave one’s home behind, and undergoes a spiritual transformation.
NOMINATED FOR THE 2021 HUGO AWARDS AND THE 2020 NEBULA AWARDS FOR BEST NOVEL From the New York Times bestselling author of Star Wars: Resistance Reborn comes the first book in the Between Earth and Sky trilogy, inspired by the civilizations of the Pre-Columbian Americas and woven into a tale of celestial prophecies, political intrigue, and forbidden magic. A god will return When the earth and sky converge Under the black sun In the holy city of Tova, the winter solstice is usually a time for celebration and renewal, but this year it coincides with a solar eclipse, a rare celestial event proscribed by the Sun Priest as an unbalancing of the world. Meanwhile, a ship launches from a distant city bound for Tova and set to arrive on the solstice. The captain of the ship, Xiala, is a disgraced Teek whose song can calm the waters around her as easily as it can warp a man’s mind. Her ship carries one passenger. Described as harmless, the passenger, Serapio, is a young man, blind, scarred, and cloaked in destiny. As Xiala well knows, when a man is described as harmless, he usually ends up being a villain. Crafted with unforgettable characters, Rebecca Roanhorse has created an epic adventure exploring the decadence of power amidst the weight of history and the struggle of individuals swimming against the confines of society and their broken pasts in the most original series debut of the decade.
From an award-winning author, astronomer, and anthropologist, an exploration of the scientific and cultural significance of the mesmerizing cosmic display. Since the first humans looked up and saw the sun swallowed by darkness, our species has been captivated by solar eclipses. Astronomer and anthropologist Anthony Aveni explains the history and culture surrounding solar eclipses, from prehistoric Stonehenge to Babylonian creation myths, to a confirmation of Einstein’s theory of general relativity, to a spectacle that left New York City in the moon’s shadow, to future eclipses that will capture human imaginations. In one accessible and engaging read, Aveni explains the science behind the phenomenon, tracks eclipses across the ancient world, and examines the roles of solar eclipses in modern times to reveal the profound effects these cosmic events have had on human history. Colored by his own experiences—Aveni has witnessed eight total solar eclipses in his lifetime—his account of astronomy’s most storied phenomenon will enthrall anyone who has looked up at the sky with wonder. “Aveni’s authoritative but accessible text is the clearest statement of the way our perception of eclipses has changed over the centuries.” —Stuart Clark, New Scientist “Authoritative and engaging.” —Marcelo Gleiser, NPR’s 13.7 “A recommended way to share the spirit of the occasion.” —Laurence A. Marschall, Natural History magazine “Everything you need to enjoy a solar eclipse—and even predict one, just like the Babylonians did! Aveni’s entertaining explorations show the very different impacts eclipses have had on past and present cultures.” —David DeVorkin, National Air and Space Museum, Smithsonian Institution
