On October 12, 1972, a plane carrying a team of young rugby players crashed into the remote, snow-peaked Andes. Out of the 45 original passengers and crew, only 16 made it off the mountain alive. For 10 excruciating weeks, they suffered deprivations beyond imagining, confronting nature head-on at its most furious and inhospitable. And to survive, these men and women not only had to keep their faith; they had to make an impossible decision: Should they eat the flesh of their dead friends?

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Oliver Sacks is well known as an explorer of the human mind - a neurologist with a gift for complex, insightful portrayals of people and their conditions. However, he is also a card-carrying member of the American Fern Society, and since childhood has been fascinated by these primitive plants and their ability to survive and adapt in many climates. Oaxaca Journal is Sacks' spellbinding account of his trip with a group of fellow fern enthusiasts to the beautiful, history-steeped province of Oaxaca, Mexico.

After the Soviet Union proved to the United States that it possessed an operational intercontinental ballistic missile with the launch of Sputnik in October 1957, the world watched anxiously as the two superpowers engaged in a game of nuclear one-upmanship. Amid this rising tension, eccentric physicist Nicholas Christofilos brought forth an outlandish, albeit ingenious, idea to defend the US from a Soviet attack: detonating nuclear warheads in space to create an artificial radiation belt that would fry incoming ICBMs. Known as Operation Argus, this plan is the most secret and riskiest experiment in history, and classified details of these nuclear tests have been long obscured.

Edison and Tesla were arch-enemies with competing visions as to how to electrically empower America. Their hostility played out in the infamous War of the Currents. Radio, television, robots, electric cars, self-driving cars, solar heating, the internet, and the cellphone were on the mind of one or the other of these geniuses. Which one ultimately proved to have the more accurate and enduring vision for the world? Who is in the news today and why? Come and find out the answers.

La Ruota di medicina ci fa scoprire che la natura non è un oggetto al nostro servizio, ma un sistema complesso e vivente che continuamente si trasforma, i cui equilibri dipendono anche da noi e dal nostro comportamento quotidiano nei suoi confronti.

Although dinosaur fossils were first found in England, a series of dramatic discoveries during the late 1800s turned North America into a world center for vertebrate paleontology. At the same time, the United States emerged as the world’s largest industrial economy, and creatures like tyrannosaurus, brontosaurus, and triceratops became emblems of American capitalism. Large, fierce, and spectacular, American dinosaurs dominated the popular imagination, making front-page headlines and appearing in feature films.

Coyote America is both an environmental and a deep natural history of the coyote. It traces both the five-million-year-long biological story of an animal that has become the "wolf" in our backyards and its cultural evolution from a preeminent spot in Native American religions to the hapless foil of the Road Runner. A deeply American tale, the story of the coyote in the American West and beyond is a sort of Manifest Destiny in reverse.

En 1776, les 13 colonies anglaises qui deviendront les 13 premiers États des États-Unis d'Amérique déclaraient leur indépendance, mais l'Angleterre, pour des raisons politiques et économiques, ne leur a octroyé cette indépendance qu'en 1783 après une guerre qui aura duré sept ans.

In this intimate portrait of an island lobstering community and an eccentric band of renegade biologists, journalist Trevor Corson escorts the listener onto the slippery decks of fishing boats, through danger-filled scuba dives, and deep into the churning currents of the Gulf of Maine to learn about the secret undersea lives of lobsters.

Built of titanium and a chrome-nickel alloy known as Inconel X, the X-15 was the fastest plane ever built, streaking through the lower reaches of outer space even before the first space capsules reached orbit. First tested in 1959, the X-15 proved to be a crucial testing ground for the astronauts and hardware in the Mercury, Gemini, Apollo, and even the Space Shuttle programs. Celebrated reporter Richard Tregaskis spent time with the pilots, engineers, and other key personnel involved in the project.

Why did the US intelligence services fail so spectacularly to know about the Soviet Union's nuclear capabilities following World War II? As Vince Houghton, historian and curator of the International Spy Museum in Washington, DC, shows us, that disastrous failure came just a few years after the Manhattan Project's intelligence team had penetrated the Third Reich and knew every detail of the Nazi's plan for an atomic bomb. What changed and what went wrong?

"In mid-July of 1879, John Muir sailed for the first time through the sheer-walled fjords of Alaska's Inside Passage. 'Never before this,' he wrote, 'had I been embosomed in scenery so hopelessly beyond description.' During the previous 15 years, Muir had vanished into the north woods of Canada, walked a thousand miles from Kentucky to the Gulf of Mexico, and nested himself in the granite heart of California's Sierra Nevada mountains. Wild nature burned with volcanic intensity in the core of John Muir's soul."

For two years, Scots-born John Muir lived in a small cabin along the Yosemite creek, observing the valley's natural beauty and reading Emerson under the stars. The experience forged a lifelong affinity with the site, which would result in its establishment as a national park in 1890. Originally written as a guidebook to the park, The Yosemite describes every aspect of wildlife and landscape that one might encounter there.
