In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons.

Dark Data explores the many ways in which we can be blind to missing data and how that can lead us to conclusions and actions that are mistaken, dangerous, or even disastrous. Examining a wealth of real-life examples, from the Challenger shuttle explosion to complex financial frauds, Hand gives us a practical taxonomy of the types of dark data that exist and the situations in which they can arise, so that we can learn to recognize and control for them.

In early May 2006, a young British climber named David Sharp lay dying near the top of Mount Everest while forty other climbers walked past him on their way to the summit. A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.

What are the politics of nature? Who owns it, where is it, what role does it play in our lives? Does it need to be tamed? Are we ourselves natural? In A Darker Wilderness, a constellation of luminary writers reflect on the significance of nature in their lived experience and on the role of nature in the lives of Black folks in the United States. Each of these essays engages with a single archival object, whether directly or obliquely, exploring stories spanning hundreds of years and thousands of miles, traveling from roots to space and finding rich Blackness everywhere.

Here, for the first time, in a brilliant, panoramic portrait by the Pulitzer Prize-winning author of The Making of the Atomic Bomb, is the definitive, often shocking story of the politics and the science behind the development of the hydrogen bomb and the birth of the Cold War. Based on secret...

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Wilderness guide and lifelong Alaskan Bjorn Dihle weaves personal experience with historical and contemporary accounts to explore the world of brown bears - from encounters with the Lewis and Clark Expedition to frightening attacks including the famed death of Timothy Treadwell, the controversies related to bear hunting, the animal's place in native cultures, and the impacts on the species from habitat degradation and climate change.

On May 28, 1914, the RMS Empress of Ireland began her 192nd trip across the Atlantic from Quebec City, Canada, en route to Liverpool, England, carrying 1,056 passengers and a crew of 423. In the early hours of May 29, fog descended on the St. Lawrence River, and the ocean liner was rammed by the Storstad, a Norwegian coal ship. In the fourteen minutes it took for the Empress of Ireland to sink, there was time to launch only four of the forty lifeboats, and rather than women and children first, it was everyone for themselves.

Because of the diseases it spreads, we have learned to distance ourselves from our waste, but the long line of engineering marvels we’ve created to do so - from Roman sewage systems and medieval latrines to the immense, computerized treatment plants we use today - has also done considerable damage to the Earth’s ecology. Now scientists tell us: We’ve been wasting our waste.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

Embark on a captivating journey into the origins of human skin color with this thought-provoking audiobook. Through in-depth genetic studies and poignant narratives, it challenges conventional notions, revealing the intricate interplay of genetics, environment, and societal influences. From the diverse ethnic groups worldwide to the persecution of Albinos in Sub-Saharan Africa, it offers a compelling exploration of identity and diversity.

Our historians today often only emphasize negative interactions between the races, and dismally fail to relay a COMPLETE HISTORY, which tells of how the noble ones of all races protected and helped one another in our country. From the inspiring examples of parents, grandparents, and ancestors, Debra undoubtedly drew strength. Many of their stories are in the opening chapters of the book. The narrative continues through the turbulent 1960s and 1970s.

Brought to you by Penguin. At night the senses become reordered. Hearing becomes privileged over vision, and we edge forward arms outstretched, feeling our way through the inky blackness. It is after dark that the human being becomes more ‘animal’, more sensitive to Nature. But the lights of...

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

Best New Books on Space 2024 – Forbes ‘Rarely is a non-fiction book about science this engaging’ – Forbes Why darkness is so important – to plants, to animals, and to ourselves – and why we must protect it all costs. Darkness is the first thing we know in our human existence. Safe...

When the sun has set, things get interesting with wild animals. Where people wait for buses during the day, a family of raccoons rummages through the trash can. Foxes and skunks search for food; fireflies send flashing signals to potential mates; owls and bats fly overhead. Night is not just a time, but a diverse habitat that we still know too little about. Wildlife biologist Sophia Kimmig is on the trail of the secrets of the night.

As development and subsequent habitat destruction accelerate, there are increasing pressures on wildlife populations. But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity. Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and this audio edition will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

Well-heeled American corporations have long had a financial stake in undermining scientific consensus and manufacturing uncertainty. In The Triumph of Doubt, former Obama and Clinton official David Michaels details how corrupt science becomes public policy - and where it's happening today.

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.
