Math has a reputation for being inaccessible. People think that it requires a special gift or that comprehension is a matter of genes. Yet, the greatest mathematicians throughout history, from Rene Descartes to Alexander Grothendieck, have insisted that this is not the case.

A "powerful, passionate, and inspiring" (New York Times) journey through the beauty and power of mathematics New York Times Bestseller What if you had to take an art class in which you were only taught how to paint a fence? What if you were never shown the paintings of van Gogh and Picasso...

In Climate Hope, journalist David Geselbracht blends in-depth research, expert interviews, and on-the-ground reporting in multiple countries, revealing remarkable efforts to identify the causes and impacts of climate change—and devise crucial ways to address them. The scale of the challenge is clear in the range of fields he covers, from glaciology and climate science to law and diplomacy. But in drawing these approaches together, he shares stories of hope, awe, and wonder that encourage us to confront this long-term, world-warping phenomenon with a renewed sense of purpose and possibility.

The world needs to turn away from fossil fuels and use clean, renewable sources of energy as soon as we can. Failure to do so will cause catastrophic climate damage sooner than you might think, leading to loss of biodiversity and economic and political instability. But all is not lost! We still have time to save the planet without resorting to 'miracle' technologies. We need to wave goodbye to outdated technologies, such as natural gas and carbon capture, and repurpose the technologies that we already have at our disposal.

Daniel K. Sodickson―a physicist and biomedical imaging innovator―explores the rich history and surprising future of vision, from the evolution of eyes to emerging high-tech devices. Beginning in the early oceans, when organisms first developed sight, The Future of Seeing tells the stories of the many remarkable tools people have invented to extend our natural vision.

In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.

In the vein of #1 New York Times bestseller Soul Surfer, this inspiring story of loss and resilience follows the Reeder family after a horrific shark attack. A two-week vacation to the Florida Keys meant Mary and Jameson Sr. could share the beauty of their favorite turquoise-blue waters with...

Did you know... Medical interventions have become the third leading cause of death in America. An estimated 10 percent of Americans are implanted with medical devices -- like pacemakers, artificial hips, cardiac stents, etc. The overwhelming majority of high-risk implanted devices have never...

A noted space expert explains the current revolution in spaceflight, where it leads, and why we need it. Astronautical engineer Robert Zubrin spells out the potential of these new developments in an engrossing narrative that is visionary yet grounded by a deep understanding of the practical challenges. Fueled by the combined expertise of the old aerospace industry and the talents of Silicon Valley entrepreneurs, spaceflight is becoming cheaper.

Drawing intriguing parallels between the present era of quantum physics and past episodes of scientific confusion, Beyond the Quantum tells the story of how pilot-wave theory was discovered and abandoned, revived and reconstructed, and how today it can pave the way to a new and radical physics beyond the quantum.

From the big bang to the origin and evolution of intelligent life in a search for the meaning of human existence, Why Are We Here?, by author Bruce Brodie, offers a look at evolution and the future of life on the planet.

How did we end up here, masters of scientific insight, purveyors of ever more powerful technologies, astride the burning planet that created us, and now responsible for cleaning up the mess and determining the future direction of all of life? And what do we do about it? Technology is Dead is a book that attempts to answer both of those questions. It is a book of both challenge and hope, written for those who are able or willing to lead us out of our global predicament.

Each day we are exposed to a myriad of natural and human-made chemicals in our food, drinking water, air, soil, at home or at the workplace-pesticide residues, food additives, drugs, household products-but how can we gauge the human health risk posed by these chemicals? Should we believe the somber headlines that depict a serious threat for humans and the environment, or should we follow the reassuring voices of others who claim that the angst is totally unfounded?

Force explores how humans interact with the material world in the course of their everyday activities. Celebrated author Henry Petroski draws from a variety of disciplines to make the case that force—represented especially by our sense of touch—is a unifying principle that pervades our lives. In the wake of a prolonged global pandemic that increasingly cautioned us about contact with the physical world, Petroski offers a new perspective on the importance of the sensation and power of touch.

With triplet eight-year-old daughters, I don’t get four-hour study blocks in a quiet corner of the library. I get an hour here or 15 minutes there. This book is for those commuters, busy parents, and working students who need a “fit it in” approach to studying pharmacology. This book has multiple rapid-fire questions, answers, rationales, and mnemonics that you can do alone or with a partner to help you understand pharmacology better and remember the content longer.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

We live in a world awash in manmade chemicals, from the pesticides on our front lawns to the diesel exhaust in the air we breathe. Although experts are beginning to understand the potential dangers of these substances, there are still more than 80,000 synthetic compounds that have not been sufficiently tested to interpret their effects on human health.

In the seventy years since the disappearance of Amelia Earhart and her navigator Fred Noonan during a flight over the Central Pacific, their fate has remained one of history's most debated mysteries despite dozens of books offering solutions. This book is different. It draws on thousands of never-before-published primary source documents to present a narrative that corrects decades of misconception. Ric Gillespie offers a very realistic picture of Earhart, her attempted world flight, the events surrounding her disappearance, and the U.S. government’s failed attempt to find her.

Climate change is today's news, but it isn't a new phenomenon. Centuries-long cycles of heating and cooling are well documented for Europe and the North Atlantic. These variations in climate, including the Medieval Warm Period (MWP), AD 900 to 1300, and the early centuries of the Little Ice Age (LIA), AD 1300 to 1600, had a substantial impact on the cultural history of Europe.
