The first Europeans to set foot on North America stood in awe of the natural abundance before them. The skies were filled with birds, seas and rivers teemed with fish, and the forests and grasslands were a hunter’s dream, with populations of game too abundant and diverse to even fathom. It’s no wonder these first settlers thought they had discovered a paradise of sorts. Fortunately for us, they left a legacy of copious records documenting what they saw, and these observations make it possible to craft a far more detailed evocation of North America before its settlement than any other place on the planet.

Here Steve Nicholls brings this spectacular environment back to vivid life, demonstrating with both historical narrative and scientific inquiry just what an amazing place North America was and how it looked when the explorers first found it. The story of the continent’s colonization forms a backdrop to its natural history, which Nicholls explores in chapters on the North Atlantic, the East Coast, the Subtropical Caribbean, the West Coast, Baja California, and the Great Plains. Seamlessly blending firsthand accounts from centuries past with the findings of scientists today, Nicholls also introduces us to a myriad cast of characters who have chronicled the changing landscape, from pre–Revolutionary era settlers to researchers whom he has met in the field.

A director and writer of Emmy Award–winning wildlife documentaries for the Smithsonian Channel, Animal Planet, National Geographic, and PBS, Nicholls deploys a cinematic flair for capturing nature at its most mesmerizing throughout. But Paradise Found is much more than a celebration of what once was: it is also a reminder of how much we have lost along the way and an urgent call to action so future generations are more responsible stewards of the world around them. The result is popular science of the highest order: a book as remarkable as the landscape it recreates and as inspired as the men and women who discovered it.

As Washington elites drifted toward ideological poles over the past few decades, did ordinary Americans follow their lead? In The Partisan Sort, Matthew Levendusky reveals that we have responded to this trend—but not, for the most part, by becoming more extreme ourselves. While polarization has filtered down to a small minority of voters, it also has had the more significant effect of reconfiguring the way we sort ourselves into political parties.

In a marked realignment since the 1970s—when partisan affiliation did not depend on ideology and both major parties had strong liberal and conservative factions—liberals today overwhelmingly identify with Democrats, as conservatives do with Republicans. This “sorting,” Levendusky contends, results directly from the increasingly polarized terms in which political leaders define their parties. Exploring its far-reaching implications for the American political landscape, he demonstrates that sorting makes voters more loyally partisan, allowing campaigns to focus more attention on mobilizing committed supporters. Ultimately, Levendusky concludes, this new link between party and ideology represents a sea change in American politics.

Explorer, scientist, writer, and humanist, Alexander von Humboldt was the most famous intellectual of the age that began with Napoleon and ended with Darwin. With Cosmos, the book that crowned his career, Humboldt offered to the world his vision of humans and nature as integrated halves of a single whole. In it, Humboldt espoused the idea that, while the universe of nature exists apart from human purpose, its beauty and order, the very idea of the whole it composes, are human achievements: cosmos comes into being in the dance of world and mind, subject and object, science and poetry.

Humboldt’s science laid the foundations for ecology and inspired the theories of his most important scientific disciple, Charles Darwin. In the United States, his ideas shaped the work of Emerson, Thoreau, Poe, and Whitman. They helped spark the American environmental movement through followers like John Muir and George Perkins Marsh. And they even bolstered efforts to free the slaves and honor the rights of Indians.

Laura Dassow Walls here traces Humboldt’s ideas for Cosmos to his 1799 journey to the Americas, where he first experienced the diversity of nature and of the world’s peoples—and envisioned a new cosmopolitanism that would link ideas, disciplines, and nations into a global web of knowledge and cultures. In reclaiming Humboldt’s transcultural and transdisciplinary project, Walls situates America in a lively and contested field of ideas, actions, and interests, and reaches beyond to a new worldview that integrates the natural and social sciences, the arts, and the humanities.

To the end of his life, Humboldt called himself “half an American,” but ironically his legacy has largely faded in the United States. The Passage to Cosmos will reintroduce this seminal thinker to a new audience and return America to its rightful place in the story of his life, work, and enduring legacy.

Patent law is crucial to encourage technological innovation. But as the patent system currently stands, diverse industries from pharmaceuticals to software to semiconductors are all governed by the same rules even though they innovate very differently. The result is a crisis in the patent system, where patents calibrated to the needs of prescription drugs wreak havoc on information technologies and vice versa. According to Dan L. Burk and Mark A. Lemley in The Patent Crisis and How the Courts Can Solve It, courts should use the tools the patent system already gives them to treat patents in different industries differently. Industry tailoring is the only way to provide an appropriate level of incentive for each industry.

Burk and Lemley illustrate the barriers to innovation created by the catch-all standards in the current system. Legal tools already present in the patent statute, they contend, offer a solution—courts can tailor patent law, through interpretations and applications, to suit the needs of various types of businesses. The Patent Crisis and How the Courts Can Solve It will be essential reading for those seeking to understand the nexus of economics, business, and law in the twenty-first century.
