Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

For years Charlie Burrell and his wife, Isabella Tree, farmed Knepp Castle Estate and struggled to turn a profit. By 2000, with the farm facing bankruptcy, they decided to try something radical. They would restore Knepp’s 3,500 acres to the wild. Using herds of free-roaming animals to mimic the actions of the megafauna of the past, they hoped to bring nature back to their depleted land. But what would the neighbors say, in the manicured countryside of modern England where a blade of grass out of place is considered an affront?

At the beginning of his career, Joseph Campbell developed a lasting fascination with the cultures of the Far East, and explorations of Buddhist and Hindu philosophy later became recurring motifs in his vast body of work. However, Campbell had to wait until middle age to visit the lands that inspired him so deeply. In 1954, he took a sabbatical from his teaching position and embarked on a year-long voyage through India, Thailand, Cambodia, Burma, Hong Kong, Taiwan, and finally Japan.

In 40 years, Earth's population will reach 10 billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups - Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin.

With rare detail and in consummate style, Steve Inskeep tells the story of a couple whose joint ambitions and talents intertwined with those of the nascent United States itself. Taking advantage of expanding news media, aided by an increasingly literate public, the two linked their names to the three great national movements of the time - westward settlement, women’s rights, and opposition to slavery. Together, John and Jessie Frémont took parts in events that defined the country and gave rise to a new, more global America.

She Has Her Mother's Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. We need a new definition of what heredity is and, through Carl Zimmer's lucid exposition and storytelling, this resounding tour de force delivers it.

Around the world, geophysicists and mathematicians, oceanographers and meteorologists, engineers, economists, psychologists, and philosophers have been using their expertise to develop a deep understanding of the crises we face. Greta Thunberg has created The Climate Book in partnership with more than one hundred of these experts in order to equip us all with this knowledge. Alongside them, Thunberg shares her own stories of learning, demonstrating, and uncovering greenwashing around the world. This is one of our biggest problems, she shows, but also our greatest source of hope.

If anyone could be considered a Russian counterpart to the infamous British double-agent Kim Philby, it was Oleg Gordievsky. The son of two KGB agents and the product of the best Soviet institutions, the savvy, sophisticated Gordievsky grew to see his nation's communism as both criminal and philistine. He took his first posting for Russian intelligence in 1968 and eventually became the Soviet Union's top man in London, but from 1973 on he was secretly working for MI6.

Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

“Mine” is one of the first words babies learn, and by the time we grow up, the idea of ownership seems natural, whether we are buying a cup of coffee or a house. But who controls the space behind your airplane seat: you, reclining, or the squished laptop user behind you? Why is plagiarism wrong, but it’s okay to knock off a recipe or a dress design? And after a snowstorm, why does a chair in the street hold your parking space in Chicago, while in New York you lose both the space and the chair?

As the digital era becomes increasingly pervasive, the intertwining forces of computers and espionage are reshaping the entire world; what was once the preserve of a few intelligence agencies now affects us all. Corera's compelling narrative takes us from the Second World War through the Cold War and the birth of the Internet to the present era of hackers and surveillance. The book is rich with historical detail and characters as well as astonishing revelations about espionage carried out in recent times by the United Kingdom, the United States, and China.

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

For too long, scientists have focused on the dark side of our biological heritage: our capacity for aggression, cruelty, prejudice, and self-interest. But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all our inventions - our tools, farms, machines, cities, nations - we carry with us innate proclivities to make a good society.

James Baldwin's Nobody Knows My Name records the last months of this famed American writer's 10-year self-exile in Europe, his return to America and to Harlem, and his first trip south at the time of the school integration battles. It contains Baldwin's controversial and intimate profiles of Norman Mailer, Richard Wright, and Ingmar Bergman. And it explores such varied themes as the relations between blacks and whites, the role of blacks in America and in Europe, and the question of sexual identity.

C. S. Lewis is the 20th century's most widely read Christian writer and J. R. R. Tolkien its most beloved mythmaker. For three decades they and their closest associates formed a literary club known as the Inklings, which met weekly in Lewis' Oxford rooms and a nearby pub. They read aloud from works in progress, argued about anything that caught their fancy, and gave one another invaluable companionship, inspiration, and criticism.

Nietzsche wrote that all philosophy is autobiographical, and in this vividly compelling, myth-shattering biography, Sue Prideaux brings listeners into the world of this brilliant, eccentric, and deeply troubled man, illuminating the events and people that shaped his life and work. I Am Dynamite! is the essential biography for anyone seeking to understand history's most misunderstood philosopher.

Ralph Waldo Emerson is one of the most important figures in the history of American thought, religion, and literature. The vitality of his writings and the unsettling power of his example continue to influence us more than a hundred years after his death. Now Robert D. Richardson Jr. brings to life an Emerson very different from the old stereotype of the passionless Sage of Concord.

Miller, through Keats’s poetry, brilliantly resurrects and brings vividly to life, the man, the poet in all his complexity and spirit, living dangerously, disdaining respectability and cultural norms, and embracing subversive politics. Keats was a lower-middle-class outsider from a tragic and fractured family, whose extraordinary energy and love of language allowed him to pummel his way into the heart of English literature; a freethinker and a liberal at a time of repression, who delighted in the sensation of the moment.

Ranier Maria Rilke challenges you, "...to live everything. Live the questions now. Perhaps then, someday far in the future, you will gradually, without even noticing it, live your way into the answers." Rilke's ability to combine the sensual and the spiritual into an inspired vision of the art of living is brought to vivid life in his letters. Through his eyes, the everyday difficulties of love, sex, solitude, sadness, and doubt are seen as the archetypal elements of the drama called life.

Herman Melville's epic novel, Moby-Dick, was a spectacular failure when it was published in 1851, effectively ending its author's rise to literary fame. Because he was neglected by academics for so long, and because he made little effort to preserve his legacy, we know very little about Melville, and even less about what he called his "wicked book". Scholars still puzzle over what drove Melville to invent Captain Ahab's mad pursuit of the great white whale.

Charlotte Gordon's new work is a fresh look at the lives of Mary Wollstonecraft and Mary Shelley, who together comprise one of the most illustrious and inspiring mother-daughter pairs in history.

Elegant, profound, and riveting, Mad, Bad, Dangerous to Know illuminates not only the complex relationships between three of the greatest writers in the English language and their fathers, but also illustrates the surprising ways these men surface in their work.

The library includes notes from Whitman, inscriptions from Frost, and first editions of Hobbes, Descartes, and Kant. As he begins to catalog and preserve these priceless books, Kaag rediscovers the very tenets of American philosophy.

When did we begin to be as self-centered as we are today? At what point did we expect to have the right to determine our own lives? When did we first ask the question, how can I be free? It all began in the 1790s in a quiet university town in Germany when a group of playwrights, poets, and writers put the self at center stage in their thinking, writing, and their lives.

Ted Hughes, poet laureate, was one of the greatest writers of the 20th century. With an equal gift for poetry and prose, and with a soul as capacious as any poet in history, he was also a prolific children's writer and has been hailed as the greatest English letter writer since John Keats. His magnetic personality and insatiable appetite for friendship, love, and life also attracted more scandal than any poet since Lord Byron.
