Cette "Brève histoire de l'humanité" déroule notre histoire globale, des premiers hominidés à aujourd'hui et interroge l'avenir qui nous attend. Comment l'"Homo Sapiens" a-t-il réussi à dominer la Terre ? Quelle singularité nous a permis de s'unir pour créer villes et empires, l'idée de religion, les concepts politiques de nation ou plus récemment des droits de l'homme ? Pourquoi cette dépendance et cette croyance que notre bonheur dépend de l'argent et de la possibilité de consommer ?

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.

This pioneering account sets out to understand the structure of the human brain - the place where mind meets matter. Until recently, the left hemisphere of our brain has been seen as the "rational" side, the superior partner to the right. But is this distinction true? Drawing on a vast body of experimental research, Iain McGilchrist argues while our left brain makes for a wonderful servant, it is a very poor master.

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.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites listeners to explore and learn from the elegantly simple lives of mosses.

Homo Deus explores the projects, dreams, and nightmares that will shape the 21st century - from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.

Tuberculosis has been entwined with humanity for millennia. Once romanticized as a malady of poets, today tuberculosis is a disease of poverty that walks the trails of injustice and inequity we blazed for it. In 2019, John Green met Henry, a young tuberculosis patient at Lakka Government Hospital in Sierra Leone while traveling with Partners in Health. 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 and dynamic advocate for increased access to treatment.

Over half a century ago, John Rowlands set out by canoe into the wilds of Canada to survey land for a timber company. After paddling alone for several days, he came upon "the lake of my boyhood dreams", which he named Cache Lake because there was stored the best that the north had to offer-timber for a cabin; fish, game, and berries to live on; and the peace and contentment he felt he could not live without.

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.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

Whether you live in a mountain cabin or a city loft, plant spirits present themselves to us everywhere.

The Art of Fermentation is the most comprehensive guide to do-it-yourself home fermentation ever published. Sandor Ellix Katz presents the concepts and processes behind fermentation in ways that are simple enough to guide listeners through their first experience making sauerkraut, and in-depth enough to provide greater understanding for experienced practitioners. While Katz contextualizes fermentation in terms of biological and cultural evolution, nutrition, and even economics, this is primarily a compendium of practical information.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

The inspiration for the BBC series of the same name. Fresh out of Glasgow Veterinary College, to the young James Herriot 1930s Yorkshire seems to offer an idyllic pocket of rural life in a rapidly changing world. But from his erratic new colleagues, brothers Siegfried and Tristan Farnon, to incomprehensible farmers, herds of semiferal cattle, a pig called Nugent and an overweight Pekingese called Tricki Woo, James find he is on a learning curve as steep as the hills around him.

This mind-bending tour of metaphysics applies philosophy to the forefront of today's knowledge. Over the course of 24 fascinating lectures, Professor Johnson thinks through the big questions about humans and the universe: The relationship between the mind and the brain, how consciousness emerges from neurochemical processes, the existence of God, human free will, the possibility of time travel, and whether we live in a multiverse or even a computer simulation.
