Gretchen Sorin recovers a forgotten history of black motorists, and recounts their creation of a parallel, unseen world of travel guides, black only hotels, and informal communications networks that kept black drivers safe. At the heart of this story is Victor and Alma Green's famous Green Book, begun in 1936, which made possible that most basic American right, the family vacation, and encouraged a new method of resisting oppression.

Nuestros huesos son los testigos silenciosos de las vidas que llevamos. Nuestras historias están grabadas en su médula. Basándose en sus años de investigación y en su notable experiencia, la antropóloga forense de renombre mundial Sue Black nos lleva a un viaje de redescubrimiento, una visita guiada por el esqueleto humano que nos explica cómo la historia de la vida de cada persona se revela en sus huesos, a los que ella llama «los últimos centinelas de nuestra vida mortal que dan testimonio de cómo la hemos vivido».

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

Imagine a region in space where the force of gravity is so strong that nothing - not even light - can escape. This phenomenon is a black hole: one of the most exotic, mind-boggling, and profound subjects in astrophysics. Nearly everyone has heard of black holes, but few people outside of complex scientific fields understand their true nature and their implications for our universe. No movie, novel, or other fictional treatment of black holes matches Professor Filippenko’s absorbing presentation of the actual science behind these amazing objects.

Bears have always held a central place in our collective memory, from Indigenous folklore and Greek mythology to nineteenth-century fairytales and the modern toy shop. But as humans and bears come into ever-closer contact, our relationship nears a tipping point. Today, most of the eight remaining bear species are threatened with extinction. Some, such as the panda bear and the polar bear, are icons of the natural world; others, such as the spectacled bear and the sloth bear, are far less known.

For decades, coal has been crucial to America's culture, society, and environment, an essential ingredient in driving out winter's cold, cooking meals, and lighting the dark. In the coalfields and beyond, Bob Wyss describes how this magical elixir sparked the Industrial Revolution, powered railroads, and built urban skylines, while providing home comforts for families.

Black holes are some of the most fascinating phenomena in the natural universe. In this beautiful pocket volume, Odenwald explores the science behind black holes in simple and accessible language. He explains what black holes are, how they come into existence, and how they affect the universe around us. Taking into consideration subjects such as gravity, quantum mechanics, the holographic principle and thermodynamics along the way, The Essential Book of Black Holes provides the perfect starting point for anyone interested in the subject.

When John and Jean Silverwood, both experienced sailors, decided to give their four children a taste of life on the high seas, they hoped the trip would offer important learning experiences - not only about the natural world but about the beauty of human life stripped down to its essence, far from civilization. But the adventure that awaited them would surpass anything they could have imagined.

Black holes are a constant source of fascination to many due to their mysterious nature. This Very Short Introduction audiobook addresses a variety of questions, including what a black hole actually is, how they are characterized and discovered, and what would happen if you came too close to one.

Despite their cultural influence, the grand narrative of the dinosaur story is rarely told. Most of us have heard of Stegosaurus and Tyrannosaurus, but these two dinosaurs lived more than eighty million years apart—a greater span of time than the entire post-T. rex history of the planet. Furthermore, we often know even less about the environments these animals lived in. The Shortest History of the Dinosaurs tells the full story, a 230-million-year epic of small beginnings, spectacular golden periods, and eventual global domination.

Wikipedia definisce bigiotteria gli oggetti in cui "la valenza estetica compensi la modestia del valore intrinseco dei componenti". È esattamente quello di cui si occuperà "Bigiotteria": significativi reperti dell'attuale fase evolutiva che vengono spesso giudicati irrilevanti.

In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Drawing on a variety of sources from film, literature, and popular culture, and analyzing different historical moments, including the establishment of the Wilderness Act in 1964 and the aftermath of Hurricane Katrina, Finney reveals the perceived and real ways in which nature and the environment are racialized in America. Looking toward the future, she also highlights the work of African Americans who are opening doors to greater participation in environmental and conservation concerns.

This audio edition is narrated with dazzling enthusiasm by the author, Dr Becky Smethurst. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy...

Black holes, predicted by Albert Einstein's general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality - a viewpoint many shared. After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical "laboratories".

Edwin Black, award-winning author of IBM and the Holocaust, has mined scores of corporate and governmental archives to assemble thousands of previously uncovered and long-forgotten documents and studies into this dramatic story. Black traces a continuum of rapacious energy cartels and special interests dating back nearly 5,000 years, from wood to coal to oil, and then to the bicycle and electric battery cartels of the 1890s, which created thousands of electric vehicles that plied American streets a century ago.

Delve deeper into the scientific terms and theories at the core of the Peabody-winning, cult favorite show. With exclusive insights from the show's cocreator, Graeme Manson, and science consultant Cosima Herter, The Science of Orphan Black takes you behind the closed doors of the Dyad Institute and inside Neolution.

At age 19, pilot Dale Black miraculously survived an airplane crash that killed the other two pilots on board. Hovering between life and death for three days, he had a breathtaking experience of heaven. Against all odds and with insurmountable injuries, Capt. Black recovered from his injuries and returned to fly airplanes as a professional pilot. For 40 years he kept the story to himself at the urging of his grandfather to "live" his experience rather than talk about it.
