The next time you find yourself drawn outside to gaze at the night sky with wonder and longing, take this book along (with a flashlight) to help you leapfrog through spacetime. The curious reader hungry for knowledge about the substance of Earth, Moon, Sun, the galaxies, even the "Search for Extraterrestrial Intelligence" will find in these pages an almost random dipping into the history of astronomy and the cosmos, to be experienced as one might consume bon-bons, or-for those looking to return to earthier roots--tomatoes, potatoes and spinach. What these "Tidbits" have to offer you is not so much a perfectly balanced meal as a scattering of all my favorite morsels, an offering I encourage you to consume as your appetite dictates
Filled with unexpected good news about growing older, Winter’s Graces highlights eleven qualities that ripen with age—including audacious authenticity, creative ingenuity, necessary fierceness, self-transcending generosity, and a growing capacity to savor life and to ride its ups and downs with humor and grace. Decades of research have established that the catastrophic conditions often associated with late life, such as severe dementia and debilitating frailty, are the exception, not the rule. Still, the mistaken idea that aging equals devastating decline persists, causing enormous and unnecessary suffering, especially for women. Drawing on decades of experience as a psychology professor and psychotherapist, Susan Stewart, PhD, weaves together inspiring folk stories that illustrate the graces of winter and recent research that validates them, along with a wealth of user-friendly tools and practices for amplifying these graces and bringing them to life. Written primarily for women over 50 seeking good news about growing older, Winter’s Graces offers adults of all ages a compelling vision of aging that celebrates its many gifts, acknowledges its challenges, and reveals how the last season of life can be the most fulfilling of all.
An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.
Have you always wanted to explore the Moon like Neil Armstrong or the eleven other astronauts who have walked on its surface? You can tour the Moon from your own backyard with a small telescope or binoculars. This book will point you to the Sea of Tranquility (the landing spot for Apollo 11) and many other fascinating features you can spot on the Moon's surface. Beginning with the New Moon, as each day passes, an additional slice of the Moon becomes visible. With each new slice comes new craters, lunar seas and jagged mountain ranges. This easy-to-use, illustrated reference book enables everyone, young and old, to better appreciate our nearest neighbour in space.
Twenty years after Isaac Asimov praised Timothy Ferris's GALAXIES as the most beautiful book ever published, MAGNIFICENT UNIVERSE establishes a new standard of excellence in depicting space. No other book even comes close. Ken Croswell takes us across the known universe - from the planets of the Sun to the stars of the Galaxy to the galaxies of the Cosmos. This is, simply, the most beautiful astronomy book in existance. The exploration of space by telescope and space probe continues at an exhilarating pace. While many think that only the Hubble telescope has new photographs of the heavens to offer, MAGNIFICENT UNIVERSE draws not only on Hubble but on fifty different sources. With the latest, stunning astronomical vistas, this lavish book allows us to experience the universe as never before.
How much do you know about the radiation all around you? Your electronic devices swarm with it; the sun bathes you in it. It's zooming at you from cell towers, microwave ovens, CT scans, mammogram machines, nuclear power plants, deep space, even the walls of your basement. You cannot see, hear, smell or feel it, but there is never a single second when it is not flying through your body. Too much of it will kill you, but without it you wouldn't live a year. From beloved popular science writer Bob Berman, Zapped tells the story of all the light we cannot see, tracing infrared, microwaves, ultraviolet, X-rays, gamma rays, radio waves and other forms of radiation from their historic, world-altering discoveries in the 19th century to their central role in our modern way of life, setting the record straight on health costs (and benefits) and exploring the consequences of our newest technologies. Lively, informative, and packed with fun facts and "eureka moments," Zapped will delight anyone interested in gaining a deeper understanding of our world.
