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.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

World renowned scientist, Dr. Gerald Pollack, takes us on a fantastic voyage through water, showing us a hidden universe teeming with physical activity - providing simple explanations for everyday phenomena, which you have inevitably seen but not really understood. Have you ever wondered how do clouds made up of dense water droplets manage to float in the sky? Why don't your joints squeak as they rub together? Why do you sink in dry sand, but not in wet sand? Pollack uses a recent and fundamental scientific finding - EZ water - to help explain these and many other head-scratchers.

In each episode, we bring you riveting interviews with individuals who have had encounters with the elusive Sasquatch. Each one of these stories will leave you wanting more. But that's not all. We go beyond the encounters and explore the realm of Bigfoot research from a critical thinking perspective. We bring you interviews with field researchers who dedicate their lives to unraveling the mysteries surrounding Sasquatch. These dedicated individuals use hard science and rigorous methodologies to investigate the existence of this legendary creature. Through thought-provoking discussions, we aim ...

A Short History of Nearly Everything is Bill Bryson’s quest to find out everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us. His challenge is to take subjects that normally bore the pants off most of us and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. It's not so much about what we know, as about how we know what we know.

In this stunning narrative spanning more than 200 million years, Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field - discovering 10 new species and leading groundbreaking scientific studies and fieldwork - masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy.

The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of incredible scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for evolution.

As one of the most celebrated cave divers in the world, Jill Heinerth has seen the planet in a way almost no one has. In a workday, she might swim below your home, through conduits in volcanoes or cracks in the world's largest iceberg. She's an explorer, a scientist's eyes and hands underwater - discovering new species and examining our finite freshwater reserves - and a filmmaker documenting the wonders of underwater life. Often the lone woman in a male-dominated domain, she tests the limits of human endurance at every tight turn, risking her life with each mission.

CBC Radio's Quirks and Quarks covers the quirks of the expanding universe to the quarks within a single atom... and everything in between.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

For months in early 1980, scientists, journalists, and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died, including newlywed logger John Killian (for years afterward, his father searched for him in the ash), scientist Dave Johnston, and celebrated local curmudgeon Harry Truman. The lives of many others were forever changed.

Gardening in Canada podcast is a podcast dedicated to the science of gardening. From cold climate gardening to indoor plants a soil scientist takes you on the journey of being a plant hobbyist

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.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

There are few remaining frontiers on our planet. But perhaps the wildest, and least understood, are the world's oceans: too big to police, and under no clear international authority, these immense regions of treacherous water play host to rampant criminality and exploitation.

Deep is a voyage from the ocean's surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freediving - in which competitors descend to great depths on a single breath - James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena.
