What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

For decades the practice of manifestation has been widely dismissed as self-involved, materialistic pseudoscience. But as neuroscientist and recognized compassion leader Dr. James Doty reveals, manifestation introduces us to different possibilities, and it lays the groundwork for a kinder, better world. Doty grounds us in the practices that change our brain structures: attention, meditation, visualization, and compassion. This mind magic allows us to move through the world in ways that help us see clearly.

Este libro sobre lo grande, lo pequeño y la relación entre ambos nos entrega una innovadora respuesta a las grandes preguntas sobre la existencia humana. El tamaño no es solo una propiedad más de lo que nos rodea, sino que puede cambiar nuestra forma de verlo absolutamente todo.

Tell a stranger that you talk to yourself, and you’re likely to get written off as eccentric. But the truth is that we all have a voice in our head. When we talk to ourselves, we often hope to tap into our inner coach but find our inner critic instead. When we’re facing a tough task, our inner coach can buoy us up: Focus - you can do this. But, just as often, our inner critic sinks us entirely: I’m going to fail. They’ll all laugh at me. What’s the use?

When it comes to climate change, the media, politicians, and other prominent voices have declared that "the science is settled." In reality, the long game of telephone from research to reports to the popular media is corrupted by misunderstanding and misinformation. Core questions - about the way the climate is responding to our influence, and what the impacts will be - remain largely unanswered. The climate is changing, but the why and how aren't as clear as you've probably been led to believe.

Including letters, speeches, articles, and essays written before 1935, this collection offers a complete portrait of Einstein as a humanitarian and as a human being trying to make sense of the world changing around him.

Nothing Like It in the World is the story of the men who built the transcontinental railroad. In Ambrose's hands, this enterprise comes to life. The U.S. government pitted two companies - the Union Pacific and the Central Pacific railroads - against each other in a race for funding, encouraging speed over caution. As its peak the work force approached the size of Civil War armies, with as many as 15,000 workers on each line. The surveyors, the men who picked the route, lived off buffalo, deer, and antelope.

In Reconnecting to the Source he unpacks the science behind spiritual experience, investigating the ways in which we can access realms of experience beyond the everyday. It is in these moments, when our conscious minds are in contact or perhaps even overridden by our unconscious selves, that we can explore the depths of spiritual meaning. In addition to a foreword by Deepak Chopra, the book includes new, never before published contributions from a long list of well-known writers and public figures.

We need land for so many of humanity's growing needs, such as food, renewable energy, carbon storage and housing. Traditionally, we've stolen it from nature, but this has led to a mounting toll of extinction and pollution that is now punishing us. So, as there's no land left to take, how do we get more from the same, or preferably less. In Land Smart, Tom Heap tours the British countryside meeting the farmers, scientists, conservationists and even warehouse managers who are solving the most pressing challenges facing our countryside and the world.

For thousands of years, humans have been the architects of the natural world. Our activities have permanently altered the environment – for good and for bad. Nature’s Ghosts examines how the planet would have looked before humans scrubbed away its diversity: from landscapes carved out by megafauna to the primeval forests that emerged following the last ice age, and from the eagle-haunted skies of the Dark Ages to the flower-decked farms of more recent centuries.

From the New York Times best-selling author of Seven Brief Lessons on Physics, The Order of Time, and Helgoland, a closer look at the mind-bending nature of the Universe. What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his life exploring these questions. He tells us how our understanding of reality has changed over the centuries and how physicists think about the structure of the Universe today.

With chronic disorders among American children reaching epidemic levels, hundreds of thousands of parents are desperately seeking solutions to their children's declining health, often with little medical guidance from the experts. What's Making Our Children Sick? convincingly explains how agrochemical industrial production and genetic modification of foods is a culprit in this epidemic.

In this revolutionary, comprehensive, and accessible guide on how the brain learns, discover how to study more efficiently and effectively, shrug away exam stress, and most of all, enjoy learning.

Sometimes the bravest thing we can do while facing an existential crisis is imagine life on the other side. This provocative and joyous book maps an inspiring landscape of possible climate futures.

Alaska's Arctic National Wildlife Refuge, home to only a handful of people, is a harsh and lonely place. So when James Campbell's cousin Heimo Korth asked him to spend a summer building a cabin in the rugged Interior, Campbell hesitated about inviting his 15-year-old daughter, Aidan, to join him. Would she be able to withstand clouds of mosquitoes, the threat of grizzlies, bathing in an ice-cold river, and hours of grueling labor peeling and hauling logs? But once there, Aidan embraced the wild.

In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special brand-new audio edition is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than 200 species. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin.

Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence. Scientists and engineers have struggled with their own gaseous demons.

We've all seen the happiness on the face of a child while playing in the school yard. Or the blissful abandon of a golden retriever racing across a lawn. This is the joy of play. By definition, play is purposeless, all-consuming, and fun. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. We are designed by nature to flourish through play.

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.
