In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.

In this groundbreaking work, evolutionary biologist Jared Diamond stunningly dismantles racially based theories of human history by revealing the environmental factors actually responsible for history's broadest patterns. It is a story that spans 13,000 years of human history, beginning when Stone Age hunter-gatherers constituted the entire human population. Guns, Germs, and Steel is a world history that really is a history of all the world's peoples, a unified narrative of human life.

Since its publication in 1977, The Unsettling of America has been recognized as a classic of American letters. In it, Wendell Berry argues that good farming is a cultural and spiritual discipline. Today’s agribusiness, however, takes farming out of its cultural context and away from families. As a result, we as a nation are more estranged from the land - from the intimate knowledge, love, and care of it.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

In 2019, author John Green met Henry Reider, a young tuberculosis patient at Lakka Government Hospital in Sierra Leone. John be­came fast friends with Henry, a boy with spindly legs and a big, goofy smile. In the years since that first visit to Lakka, Green has become a vocal advocate for increased access to treatment and wider awareness of the healthcare inequi­ties that allow this curable, preventable infec­tious disease to also be the deadliest, killing over a million people every year. In Everything Is Tuberculosis, John tells Henry’s story.

Eine Welt ohne Physiker wäre möglich, aber unberechenbar. Zum Glück geht es in Staffel 12 weiter mit diesen drei: Moderator Jens Schröder entdeckt mit den Physikern Michael Büker und Johannes Kückens neue Wissensschätze. Und weil ja genau genommen ALLES Physik ist, darf die Themenwahl wieder gewohnt bunt aussehen: Es geht auf Tour zu den allerbesten Planeten-Reisezielen und an den Beginn des Atomzeitalters. Wir bewegen uns mit Schallgeschwindigkeit durch Cappuccino und werfen einen wissenschaftlich gestützten Blick auf den Ursprung von allem – und auch auf unseren Frühstücksteller.

After sailing 300,000 miles and weathering dozens of storms in all the world's oceans, John Kretschmer has plenty of stories and advice to share.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

Sadhguru, founder of Isha Foundation is a yogi, mystic and spiritual master with a difference. An arresting blend of profundity and pragmatism, his life and work serve as a reminder that inner sciences are not esoteric philosophies from an outdated past, but a contemporary science vitally relevant to our times.

Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the Nile. He followed the river for nine months, over 4,000 miles, through six nations - Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt - to the Mediterranean coast.

Drawing on 40 years of research and a treasure trove of new information, Tesla: Wizard at War provides a comprehensive view of Tesla's discoveries, which continue to influence today's military technology and diplomatic strategies. One of the world's leading Tesla experts, Marc J. Seifer, offers new insight into the brilliant scientist's particle beam weapon (aka the "Death Ray") and explores his military negotiations with pivotal historical figures - including his links to Joseph Stalin, Vannevar Bush, General Andrew McNaughton, and Franklin Delano Roosevelt.

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

Now settled into the sleepy Yorkshire village of Darrowby, and married to Helen the farmer’s daughter, James Herriot thinks he’s finally got himself sorted. But life as a vet in the 1930s was never going to be easy. Quite aside from his unpredictable colleagues, brothers Siegfried and Tristan Farnon, he must contend with new fangled medical techniques, delivering calves after far too much home-made wine, and a grudge holding dog called Magnus who never forgets. And then, with Britain on the verge of war, James faces a decision that could separate him from Darrowby – and Helen – for ever....

A story-based show mixing spoken-word narrative, history and ideas - often to terrifying effect - that explores the space between what we think of as real and what is not; where sometimes belief can be as concrete as ‘reality,’ whatever that is… More info at www.unexplainedpodcast.com and on twitter @unexplainedpod and facebook.com/unexplainedpodcast

By 1930, no place in the world was less well explored than Greenland. The native Inuit had occupied the relatively accessible west coast for centuries. The east coast, however, was another story. In August 1930, Henry George Watkins (nicknamed “Gino”), a twenty-three-year-old British explorer, led thirteen scientists and explorers on an ambitious expedition to the east coast of Greenland and into its vast and forbidding interior to set up a permanent meteorological base on the icecap, 8,200 feet above sea level.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.
