Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth’s early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet.

For particularly brilliant theoretical physicists like James Clerk Maxwell, Paul Dirac, or Albert Einstein, the search for mathematical truths led to strange new understandings of the ultimate nature of reality. But what are these truths? What are the mysterious numbers that explain the universe? In Fantastic Numbers and Where to Find Them, the leading theoretical physicist and YouTube star Antonio Padilla takes us on an irreverent cosmic tour of nine of the most extraordinary numbers in physics, offering a startling picture of how the universe works.

Harry Cliff - a University of Cambridge particle physicist and researcher on the Large Hadron Collider - sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the "Antimatter Factory," where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up).

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

One of the most powerful questions humans ask about the cosmos is: Are we alone? While the science behind this inquiry is fascinating, it doesn’t exist in a vacuum. It is a reflection of our values, our fears, and most importantly, our enduring sense of hope. In The Possibility of Life, acclaimed science journalist Jaime Green traces the history of our understanding, from the days of Galileo and Copernicus to our contemporary quest for exoplanets. Along the way, she interweaves insights from science fiction writers who construct worlds that in turn inspire scientists.

The beloved star of Star Trek, recent space traveler, and living legend William Shatner reflects on the interconnectivity of all things, our fragile bond with nature, and the joy that comes from exploration with “the insights he’s gleaned over his long, productive life” (Booklist) in this inspiring, revelatory, and exhilarating collection of essays.

Written in History: Letters that Changed the World celebrates the great letters of world history, and cultural and personal life. Bestselling, prizewinning historian Simon Sebag Montefiore selects letters that have changed the course of global events or touched a timeless emotion—whether passion, rage, humor—from ancient times to the twenty-first century. Some are noble and inspiring, some despicable and unsettling, some are exquisite works of literature, others brutal, coarse, and frankly outrageous, many are erotic, others heartbreaking.

The art world is a much dirtier, nastier business than you might expect. Tony Tetro, one of the most renowned art forgers in history, will make you question every masterpiece you’ve ever seen in a museum, gallery, or private collection. Tetro’s “Rembrandts,” “Caravaggios,” “Miros,” and hundreds of other works now hang on walls around the globe.

One of the most influential physicists of our time, Stephen Hawking touched the lives of millions. Recalling his nearly two decades as Hawking’s collaborator and friends, Leonard Mlodinow brings this complex man into focus in a unique and deeply personal portrayal. We meet Hawking the genius, who pours his mind into uncovering the mysteries of the universe - ultimately formulating a pathbreaking theory of black holes that reignites the discipline of cosmology and paves the way for physicists to investigate the origins of the universe in completely new ways.

In the summer of 1962, a young student named Joachim Rudolph dug a tunnel under the Berlin Wall. Waiting on the other side in East Berlin were dozens of men, women, and children - all willing to risk everything to escape.

“As Albert Einstein almost certainly never said, everyone is a genius—but if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” So begins Katie Spalding’s spunky takedown of the Western canon, and how genius may not be as irrefutably great as we commonly understand. While most of us may never become Einstein, it may surprise you to learn that there’s probably a bunch of stuff you can do that Einstein couldn’t. And, as Spalding shows, the famous prodigies she explores here were quite odd by any definition.

Colonel Chris Hadfield has spent decades training as an astronaut and has logged nearly 4000 hours in space. During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, and been temporarily blinded while clinging to the exterior of an orbiting spacecraft. The secret to Col. Hadfield's success - and survival - is an unconventional philosophy he learned at NASA: prepare for the worst and enjoy every moment of it.

“Books can connect people across time zones and zip codes, across cultures, national boundaries, and historical eras”, Kakutani writes in her introduction to Ex Libris. Here listeners will discover novels and memoirs by some of the most gifted writers working today; favorite classics worth listening or relistening; and nonfiction works, both old and new, that illuminate our social and political landscape and some of today’s most pressing issues, from climate change to medicine to the consequences of digital innovation.

A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station - a candid account of his remarkable voyage, of the journeys off the planet that preceded it, and of his colorful formative years. A natural storyteller and modern-day hero, Kelly has a message of hope for the future that will inspire for generations to come. Here, in his personal story, we see the triumph of the human imagination, the strength of the human will, and the boundless wonder of the galaxy.

Dr. Carl Sagan takes us on a great adventure, offering his vivid and startling insight into the brain of man and beast, the origin of human intelligence, the function of our most haunting legends - and their amazing links to recent discoveries.
