Modern Engineering

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

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?

“Kill it with fire”, the typical first reaction to a legacy system falling into obsolescence, is a knee-jerk approach that often burns through tons of money and time only to result in a less efficient solution. This book offers a far more forgiving modernization framework, laying out smart value-add strategies and proven incremental techniques that work equally well for ancient systems and brand-new ones.

In this rich, irreverent, and compelling history, Nobel Prize-winning physicist Steven Weinberg takes us across centuries, from ancient Miletus to medieval Baghdad and Oxford, from Plato's Academy and the Museum of Alexandria to the cathedral school of Chartres and the Royal Society of London. He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world--they did not understand what there is to understand or how to understand it.

A paradigm-shifting work that revolutionizes our understanding of the origins and structure of science.

An Immense World meets Sex at Dawn in this fascinating exploration of sexual behavior throughout the animal kingdom, as evolutionary biologist Nathan H. Lents argues persuasively that many of our supposedly modern ideas about gender and human sexuality are, in fact, deeply rooted in our animal ancestors.

One of the great insights of science is that the universe has an underlying order. The supreme goal of physicists is to understand this order through laws that describe the behavior of the most basic particles and the forces between them. For centuries, we have searched for these laws by studying the results of experiments. Since the 1970s, however, experiments at the world's most powerful atom-smashers have offered few new clues. So some of the world's leading physicists have looked to a different source of insight: modern mathematics.

Best-selling author Brian Fagan brings early humans out of the deep freeze with his trademark mix of erudition, cutting-edge science, and vivid storytelling. Cro-Magnon reveals human society in its infancy, facing enormous environmental challenges - including a rival species of humans, the Neanderthals. For ten millennia, Cro-Magnons lived side by side with Neanderthals, an encounter that Fagan fills with drama.

David's unique and engaging approach to teaching HTML and CSS principles means that listeners are ready to start designing from the very first chapter without enduring an avalanche of boring jargon or dry technobabble.

Before John Deere, Ford, and International Harvester became icons of American business, they were competitors in a forgotten battle for the farm. By the turn of the 20th century, four million people had left rural America and moved to cities. With the tractor, a shrinking farm population could still feed a growing world. Tractor Wars is the untold story of industry stalwarts and disruptors, inventors, and administrators racing to invent modern agriculture - a power farming revolution that would usher in a whole new world.

The Clockwork Universe is the story of a band of men who lived in a world of dirt and disease but pictured a universe that ran like a perfect machine. A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with natures most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.

In Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.

Many are familiar with the commonly known senses - sight, hearing, taste, smell, and touch. But most do know realize that humans have other senses beyond these. This is not, however, a spooky "sixth sense" of extrasensory perception. But humans do have a different kind of sixth sense. We also have a seventh sense, and it can be debated that we have even more. These additional senses are in fact specialized systems to detect other aspects of the world that we rarely consider, though they are an important part of our everyday life.

According to veterinarian and journalist Mark Walters, we are contributing to - if not overtly causing - some of the scariest epidemics of our time. Through human stories and cutting-edge science, Walters explores the origins of seven diseases: Mad Cow Disease, HIV/AIDS, Salmonella DT104, Lyme Disease, Hantavirus, West Nile, and new strains of flu. He shows that they originate from manipulation of the environment, from emitting carbon and clear-cutting forests to feeding naturally herbivorous cows “recycled animal protein.”

In The Knife Man, Wendy Moore unveils John Hunter's murky and macabre world - a world characterized by public hangings, secret expeditions to dank churchyards, and gruesome human dissections in pungent attic rooms. This is a fascinating portrait of a remarkable pioneer and his determined struggle to haul surgery out of the realms of meaningless superstitious ritual and into the dawn of modern medicine.

Supermarket produce sections bulging with a year-round supply of perfectly round, bright red-orange tomatoes have become all but a national birthright. But in Tomatoland, which is based on his James Beard Award-winning article, The Price of Tomatoes, investigative food journalist Barry Estabrook reveals the huge human and environmental cost of the $5 billion fresh tomato industry. Fields are sprayed with more than one hundred different herbicides and pesticides. Tomatoes are picked hard and green and artificially gassed until their skins acquire a marketable hue.

René Descartes was a central figure in the scientific revolution of the 17th century. In his Discourse on Method he outlined the contrast between mathematics and experimental sciences, and the extent to which each one can achieve certainty. Drawing on his own work in geometry, optics, astronomy and physiology, Descartes developed the hypothetical method that characterizes modern science, and this soon came to replace the traditional techniques derived from Aristotle.

Humans from the earliest civilizations were spellbound by the night sky - craning their necks each night, they used the stars to orient themselves in the large, strange world around them. Stargazing is a pursuit that continues to fascinate us: from Copernicus to Carl Sagan, astronomers throughout history have spent their lives trying to answer the biggest questions in the universe. Now, award-winning astronomer Emily Levesque shares the stories of modern-day stargazers.
