“Science has a battle for hearts and minds on its hands….How good it feels to have Lisa Randall’s unusual blend of top flight science, clarity, and charm on our side.” —Richard Dawkins “Dazzling ideas….Read this book today to understand the science of tomorrow.” —Steven Pinker The bestselling author of Warped Passages, one of Time magazine’s “100 Most Influential People in the World,” and one of Esquire’s “75 Most Influential People of the 21st Century,” Lisa Randall gives us an exhilarating overview of the latest ideas in physics and offers a rousing defense of the role of science in our lives. Featuring fascinating insights into our scientific future born from the author’s provocative conversations with Nate Silver, David Chang, and Scott Derrickson, Knocking on Heaven’s Door is eminently readable, one of the most important popular science books of this or any year. It is a necessary volume for all who admire the work of Stephen Hawking, Michio Kaku, Brian Greene, Simon Singh, and Carl Sagan; for anyone curious about the workings and aims of the Large Hadron Collider, the biggest and most expensive machine ever built by mankind; for those who firmly believe in the importance of science and rational thought; and for anyone interested in how the Universe began…and how it might ultimately end.

A classic in the black literary tradition, The Spook Who Sat by the Door is both a comment on the civil rights problems in the United States in the late 1960s and a serious attempt to focus on the issue of black militancy. Dan Freeman, the "spook who sat by the door," is enlisted in the CIA's elitist espionage program. Upon mastering agency tactics, however, he drops out to train young Chicago blacks as "Freedom Fighters" in this explosive, award-winning novel. As a story of one man's reaction to ruling-class hypocrisy, the book is autobiographical and personal. As a tale of a man's reaction to oppression, it is universal.

One of The New York Times Book Review's "10 Best Books of 2015" An NYRB Classics Original The Door is an unsettling exploration of the relationship between two very different women. Magda is a writer, educated, married to an academic, public-spirited, with an on-again-off-again relationship to Hungary’s Communist authorities. Emerence is a peasant, illiterate, impassive, abrupt, seemingly ageless. She lives alone in a house that no one else may enter, not even her closest relatives. She is Magda’s housekeeper and she has taken control over Magda’s household, becoming indispensable to her. And Emerence, in her way, has come to depend on Magda. They share a kind of love—at least until Magda’s long-sought success as a writer leads to a devastating revelation. Len Rix’s prizewinning translation of The Door at last makes it possible for American readers to appreciate the masterwork of a major modern European writer.
