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.

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 We need to wave goodbye to outdated technologies, such as natural gas and carbon capture, and repurpose the technologies that we already have at our disposal.

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.

Lives of Weeds explores the tangled history of weeds and their relationship to humans. Through eight interwoven stories, John Cardina offers a fresh perspective on how these tenacious plants came about, why they are both inevitable and essential, and how their ecological success is ensured by determined efforts to eradicate them. Linking botany, history, ecology, and evolutionary biology to the social dimensions of humanity's ancient struggle with feral flora, Cardina shows how weeds have shaped - and are shaped by - the way we live in the natural world.

Predating written language and marching on through human history, the desire for ever-better timekeeping has spurred technological innovation and sparked theories that radically reshaped our understanding of the universe and our place in it. Chad Orzel, a physicist and bestselling author, continues his tradition of demystifying thorny scientific concepts by using the clocks and calendars central to our everyday activities as a jumping-off point to explore the science underlying the ways we keep track of our time.

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?

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.

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.

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.

Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts.

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.

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.

Have you ever looked at the effects of climate change and the apathy of so many around you and wondered, "What are we missing here?" Climate activist Kyle Meyaard-Schaap understands this feeling from personal experience. But in his years of speaking to and equipping Christians to work for climate action, he's seen the trend begin to shift. More and more young Christians are waking up to the realities of climate change. They want to help, but they're not sure how.

An accessible and engaging account of the mind and its connection to the brain. The mind encompasses everything we experience, and these experiences are created by the brain - often without our awareness. Experience is private; we can't know the minds of others. But we also don't know what is happening in our own minds. In this book, E. Bruce Goldstein offers an accessible and engaging account of the mind and its connection to the brain.

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.

Christopher A. Roosa grew up the eldest son of Apollo 14 astronaut and command module pilot Stuart A. Roosa. As a child of the space program, Christopher had a ringside seat at the dinner table of one of twenty-four Americans who had either entered lunar orbit or landed on the moon.

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.
