Boarding an airplane strikes at least a small sense of fear into most people. Even though we all have heard that the odds of being struck by lightning are greater than the odds of perishing in a plane crash, it still doesn't feel that way. Airplane crashes might be rare, but they do happen, and they’re usually fatal. David Soucie insists that most of these deaths could be prevented. He’s worked as a pilot, a mechanic, an FAA inspector, and an aviation executive. He’s seen death up close and personal - deaths of colleagues and friends that might have been prevented if he had approved certain safety measures in the aircrafts they were handling.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Growing up in the high desert of California, Jim Doty was poor, with an alcoholic father and a mother chronically depressed and paralyzed by a stroke. Today he is the director of the Center for Compassion and Altruism Research and Education (CCARE) at Stanford University, of which the Dalai Lama is a founding benefactor. But back then his life was at a dead end until at twelve he wandered into a magic shop looking for a plastic thumb. Instead he met Ruth, a woman who taught him a series of exercises to ease his own suffering and manifest his greatest desires.

We are often told that hard work is the key to success. But success isn’t about hard work - it’s about shortcuts. Shortcuts allow us to solve one problem quickly so that we can tackle an even bigger one. They make us capable of doing great things. And according to Marcus du Sautoy, math is the very art of the shortcut. Thinking Better is a celebration of how math lets us do more with less.

William Davis, MD, cardiologist and author of the #1 New York Times bestselling Wheat Belly books, as well as Undoctored and, most recently, Super Gut, brings the unvarnished truth about many health conditions.

Among the topics the Defiant Health Podcast covers are:--Microbiome health--The key to so ...

Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

Sand, salt, iron, copper, oil, and lithium. These fundamental materials have created empires, razed civilizations, and fed our ingenuity and greed for thousands of years. Without them, our modern world would not exist, and the battle to control them will determine our future. In Material World, Ed Conway embarks on an epic journey across continents, cultures, and epochs to reveal the underpinnings of modern life on Earth—traveling from the sweltering depths of the deepest mine in Europe to spotless silicon chip factories in Taiwan to the eerie green pools where lithium originates.

Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark.

Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet?

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

They say that only truck drivers experience the true grandeur and landscape of America. In A Trucker's Tale, Ed Miller gives an inside look at the allure of the work and the colorful characters who haul our goods on the open road.

In the 1970s, amid severe cutbacks in physics funding, a small group of underemployed physicists in Berkeley decided to throw off the constraints of academia and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued a freewheeling, speculative approach to physics. Some dabbled with LSD while conducting experiments. They studied quantum theory alongside Eastern mysticism and psychic mind reading, discussing the latest developments while lounging in hot tubs.

In 2015, Barbara Lipska - a leading expert on the neuroscience of mental illness - was diagnosed with melanoma that had spread to her brain. Within months, her frontal lobe, the seat of cognition, began shutting down. She descended into madness, exhibiting dementia- and schizophrenia-like symptoms that terrified her family and coworkers. But miraculously, the immunotherapy her doctors had prescribed worked quickly. Just eight weeks after her nightmare began, Lipska returned to normal. With one difference: she remembered her brush with madness with exquisite clarity.
