Elers Koch ("eelers kotch"), a key figure in the early days of the U.S. Forest Service, was among the first American-trained silviculturists, a pioneering forest manager, and a master firefighter. By horse and on foot, he helped establish the boundaries of most of our national forests in the West, designed new fire-control strategies and equipment, and served during the formative years of the agency.

Like many of us, Lisa Wells has spent years overwhelmed by news of apocalyptic-scale climate change and a coming sixth extinction. She did not need to be convinced of the stakes. But what can be done? Wells embarked on a pilgrimage, seeking answers in dedicated communities - outcasts and visionaries - on the margins of society.

Johns Hopkins University, one of the preeminent medical schools in the nation today, has played a unique role in the history of medicine. When it first opened its doors in 1893, medicine was a rough-and-ready trade. It would soon evolve into a rigorous science. In recent years, medical science has mapped the human genome, deployed robotic tools to perform delicate surgeries, and developed effective vaccines against a host of deadly pathogens. But this transformation could not have happened without the game-changing vision, talent, and dedication of a small cadre of individuals.

Part odyssey, part pilgrimage, this epic personal narrative follows the author’s exploration of coasts, islands, reefs, and the sea’s abyssal depths. Scientist and fisherman Carl Safina takes readers on a global journey of discovery, probing for truth about the world’s changing seas, deftly weaving adventure, science, and political analysis.

When neuroscientist Susan Barry was 50 years old, she took an unforgettable trip to Manhattan. As she emerged from the dim light of the subway into the sunshine, she saw a view of the city that she had witnessed many times in the past but now saw in an astonishingly new way. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space.

Part memoir, part manifesto, in Eat Like a Fish Bren Smith - a former commercial fisherman turned restorative ocean farmer - shares a bold new vision for the future of food: seaweed. Through tales that span from his childhood in Newfoundland to his early years on the high seas aboard commercial fishing trawlers, from pioneering new forms of ocean farming to surfing the frontiers of the food movement, Smith introduces the world of sea-based agriculture and advocates getting ocean vegetables onto American plates (there are thousands of edible varieties in the sea!).

“Leave it as it is,” Theodore Roosevelt announced while viewing the Grand Canyon for the first time. “The ages have been at work on it and man can only mar it.” Roosevelt’s pronouncement signaled the beginning of an environmental fight that still wages today. To reconnect with the American wilderness and with the president who courageously protected it, acclaimed nature writer and New York Times best-selling author David Gessner embarks on a great American road trip guided by Roosevelt’s crusading environmental legacy.

Best-selling author Steven Johnson recounts - in dazzling, multidisciplinary fashion - the story of the brilliant man who embodied the relationship between science, religion, and politics for America's Founding Fathers. The Invention of Air is a title of world-changing ideas wrapped around a compelling narrative, a story of genius and violence and friendship in the midst of sweeping historical change that provokes us to recast our understanding of the Founding Fathers.

La espléndida biografía de Alexander von Humboldt, el héroe perdido de la ciencia y padre de la ecología.

Escucha ahora la biografía definitiva de Albert Einstein, uno de los iconos del siglo XX y su mayor genio.

Acclaimed scientist and author Bernd Heinrich has returned every year since boyhood to a beloved patch of western Maine woods. What is the biology in humans of this deep-in-the-bones pull toward a particular place, and how is it related to animal homing? Heinrich explores the fascinating science chipping away at the mysteries of animal migration: how geese imprint true visual landscape memory; how scent trails are used by many creatures, from fish to insects to amphibians, to pinpoint their home if they are displaced from it; and more.

From the author of the enduring classic The Solace of Open Spaces, here is a wondrous meditation on how water, light, wind, mountain, bird, and horse have shaped her life and her understanding of a world besieged by a climate crisis. Amid species extinctions and disintegrating ice sheets, this stunning collection of memories, observations, and narratives is acute and lyrical, Whitmanesque in breadth, and as elegant as a Japanese teahouse.

Widely considered the greatest genius of all time, Albert Einstein revolutionized our understanding of the cosmos with his general theory of relativity and helped to lead us into the atomic age. Yet in the final decades of his life, he was also ignored by most working scientists, his ideas opposed by even his closest friends.

Richard Rashke leads us through the myriad of charges and countercharges, theories and facts, and reaches conclusions based solely on the evidence in hand. Originally published in 1981, his audiobook offers a vivid, edgy picture of the tensions that racked this country in the 1970s. However, the volume is not only an important historical document. Complex, fascinating characters populate this compelling insider's view of the nuclear industry.

At stake in 1896 was the new idea that some landscapes should be collectively, permanently owned by a democratic government. Although many people today think of public lands as an American birthright, their very existence was then in doubt and dependent on a merger of the talents of these two men. Natural Rivals examines a time of environmental threat and political dysfunction not unlike our own and reveals the complex dynamic that gave birth to America’s rich public lands legacy.

Kneeling in a muddy field, clutching something soft and blue-black, Marc Hamer vows he will stop trapping moles - forever. In this earnest, understated, and sublime work of nonfiction literature, the molecatcher shares what led him to this strange career: from sleeping among hedges as a homeless teen, to toiling on the railway, to weeding windswept gardens in Wales. Hamer infuses his wanderings with radiant poetry and stark, simple observations on nature’s oft-ignored details.

One of the most famous, and important, intellectuals to hail from Denmark is Niels Bohr, a world-famous physicist and one of the patriarchs of quantum theory. Given the vibrant, peaceful haven that is Denmark today, it’s somewhat ironic that Bohr played an instrumental role in the development of the atomic bomb. Even so, the truth and depth of the matter, much like the self-professed pacifist himself, is far more complex.

The battle with the Iron Legion has left The Last Horizon battered and broken, drifting in space. Varic needs an exceptional engineer to fix his ship, and there’s only one person for the job: Mell, the master Aether technician. But first, they have to break her out of prison. Mell has been captured by the Advocates, a group of superpowered vigilantes who dominate their corner of the galaxy. They are led by Starhammer, an invincible champion with a personal obsession with Mell.

Few recognize how the Great War, the industrialized slaughter that bled Europe from 1914 to 1918, shaped Einstein’s life and work. While Einstein never held a rifle, he formulated general relativity blockaded in Berlin, literally starving. He lost 50 pounds in three months, unable to communicate with his most important colleagues. Some of those colleagues fought against rabid nationalism; others were busy inventing chemical warfare - scientists trapped in the power plays of empire. Meanwhile, Einstein struggled to craft relativity and persuade the world that it was correct.

When Dr. David Hosack tilled the country's first botanical garden in the Manhattan soil more than 200 years ago, he didn't just dramatically alter the New York landscape; he left a monumental legacy of advocacy for public health and wide-ranging support for the sciences. In melodic prose, historian Victoria Johnson eloquently chronicles Hosack's tireless career to reveal the breadth of his impact. The result is a lush portrait of the man who gave voice to a new, deeply American understanding of the powers and perils of nature.
