"One hundred thousand years ago, at least six different species of humans inhabited Earth. Yet today there is only one--homo sapiens. What happened to the others? And what may happen to us? Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book that begins about 70,000 years ago with the appearance of modern cognition."--

The gripping story of the most important overlooked commodity in the world—sand—and the crucial role it plays in our lives.
After water and air, sand is the natural resource that we consume more than any other—even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids...

"Vaclav Smil's mission is to make facts matter. An environmental scientist, policy analyst, and a hugely prolific author, he is Bill Gates' go-to guy for making sense of our world. In Numbers Don't Lie, Smil answers questions such as: What's worse for the environment--your car or your phone? How much do the world's cows weigh (and what does it matter)? And what makes people happy?"--

"As robots are increasingly integrated into modern society--on the battlefield and the road, in business, education, and health--Pulitzer-Prize-winning New York Times science writer John Markoff searches for an answer to one of the most important questions of our age: will these machines help us, or will they replace us? In the past decade alone, Google introduced us to driverless cars, Apple debuted a personal assistant that we keep in our pockets,...

The most urgent story in modern tech begins not in Silicon Valley but two hundred years ago in rural England, when workers known as the Luddites rose up rather than starve at the hands of factory owners who were using automated machines to erase their livelihoods. The Luddites organized guerrilla raids to smash those machines--on punishment of death--and won the support of Lord Byron, enraged the Prince Regent, and inspired the birth of science fiction....

Thirty years ago Bill McKibben offered one of the earliest warnings about climate change. Now he broadens the warning: the entire human game, he suggests, has begun to play itself out. Bill McKibben's groundbreaking book The End of Nature -- issued in dozens of languages and long regarded as a classic -- was the first book to alert us to global warming. But the danger is broader than that: even as climate change shrinks the space where our civilization...

The invention of "waves" - as in radio waves or electromagnetic fields - has led to many great inventions. This program examines how the ability to transmit music, conversations, pictures, or data invisibly through the air, over thousands of miles, has changed our lives. Whether we are talking about cell phones, microwave ovens, TVs, RADAR systems, or any one of the thousands of other wireless technologies, all of them use radio waves to communicate....

Few substances in history have had as profound an effect on mankind as gunpowder. And yet its discovery was probably an accident - a big bang, for one. This program examines the invention and history of gunpowder, as well as its surprising ingredients. As you can imagine, making gunpowder takes some effort. Gunpowder once needed saltpeter, and saltpeter needed poop. It turns out that secretions have such an explosive character due to microscopic bacteria,...

A mother wonders, will my children love their perfect machines more than they love me, their imperfect mother? A cinematic meditation on technology and parenthood.

Robotic technology offers new capabilities and greater convenience, but at the same time, it threatens our jobs and perhaps even our identity as human beings.
