Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

The best-selling author of Truman and John Adams, David McCullough has written profiles of exceptional men and women past and present who have not only shaped the course of history or changed how we see the world but whose stories express much that is timeless about the human condition. Here are Alexander von Humboldt, whose epic explorations of South America surpassed the Lewis and Clark expedition; Harriet Beecher Stowe, "the little woman who made the big war”....

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Of all the things humans rely on plants for - sustenance, beauty, medicine, fragrance, flavor, fiber - surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable.

In this stunning narrative spanning more than 200 million years, Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field - discovering 10 new species and leading groundbreaking scientific studies and fieldwork - masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy.

Every time Bill Bryson walks out the door, memorable travel literature threatens to break out. His previous excursion on the Appalachian Trail resulted in the best seller A Walk in the Woods. Now, we follow him "Down Under" to Australia with this delectably funny, fact-filled, and adventurous performance that combines humor, wonder, and unflagging curiosity. More from Bill Bryson.

Empires of the Sea tells the story of the 50-year world war between Islam and Christianity for the Mediterranean: one of the fiercest and most influential contests in European history. It traces events from the appearance on the world stage of Suleiman the Magnificent through "the years of devastation" when it seemed possible that Islam might master the whole sea, to the final brief flourishing of a united Christendom in 1571.

In the mid-eighteenth century, as new ideas—and a new unrest—begin to sweep the Continent, a young Jew of mysterious origins arrives in a village in Poland. Before long, he has changed not only his name but his persona; visited by what seem to be ecstatic experiences, Jacob Frank casts a charismatic spell that attracts an increasingly fervent following.

As one of the most potent turning points in the country's modern history, the Opium War has since come to stand for everything that today's China seeks to put behind it. In this dramatic, epic story, award-winning historian Stephen Platt sheds new light on the early attempts by Western traders and missionaries to "open" China even as China's imperial rulers were struggling to manage their country's decline and Confucian scholars grappled with how to use foreign trade to China's advantage.

Travelers often become enchanted with the first country that captures their hearts and gives them license to be free. For Wade Davis, it was Colombia. Now in a masterly new book, Davis tells of his travels on the mighty Magdalena, the river that made possible the nation. Along the way, he finds a people who have overcome years of conflict precisely because of their character, informed by an enduring spirit of place, and a deep love of a land that is home to the greatest ecological and geographical diversity on the planet.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing.

In The Heartbeat of Trees, renowned forester Peter Wohlleben draws on new scientific discoveries to show how humans are deeply connected to the natural world. In an era of climate change, many of us fear we’ve lost our connection to nature - but Peter Wohlleben is convinced that age-old ties linking humans to the forest remain alive and intact. We just have to know where to look.

On March 8, 1421, the largest fleet the world had ever seen set sail from China. Its mission was to "proceed all the way to the ends of the earth to collect tribute from the barbarians beyond the seas" and unite the whole world in Confucian harmony. When it returned in October 1423, the emperor had fallen, leaving China in political and economic chaos. The great ships were left to rot at their moorings and the records of their journeys were destroyed. Lost in China's long isolation that followed was the knowledge that Chinese ships had reached America 70 years before Columbus.
