Neil deGrasse Tyson is arguably the most influential, acclaimed scientist on the planet. As director of the Hayden Planetarium, and host of Cosmos and StarTalk, he has dedicated his life to exploring and explaining the mysteries of the universe. Every year, he receives thousands of letters – from students to prisoners, scientists to priests. Some seek advice, others yearn for inspiration; some are full of despair, others burst with wonder. But they are all searching for understanding, meaning and truth.

In this fascinating foray into the centuries-old relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions", say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion, and access to space. Tyson and Lang call it a "curiously complicit" alliance.

Cosmos is one of the best-selling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Was there a beginning of time? Could time run backwards? Is the universe infinite, or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos, from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the big bang to black holes, via spiral galaxies and strong theory.

The final book from Professor Stephen Hawking, the best-selling author of A Brief History of Time and arguably the most famous scientist of our age, Brief Answers to the Big Questions is a profound, accessible and timely reflection on the biggest questions in science. Professor Hawking was a brilliant theoretical physicist, an influential author and thinker and a great popular communicator. Throughout his career he was asked questions by business leaders, politicians, entrepreneurs, academics and the general public on a broad range of subjects, from the origins of the universe to the future of the planet.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

With characteristic exuberance, Stephen Hawking invites us to be fellow travelers on this extraordinary voyage through spacetime, as he seeks "to combine Einstein's General Theory of Relativity and Richard Feynman's idea of multiple histories into one complete unified theory that will describe everything that happens in the universe."

Discover magazine recently called Richard Dawkins "Darwin's Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky). Now Dawkins turns his considerable intellect on religion, denouncing its faulty logic and the suffering it causes.

Earth is 4.5 billion years old. In just a fraction of that time, one species among countless others has conquered it. Us. We are the most advanced and most destructive animals ever to have lived. What makes us brilliant? What makes us deadly? What makes us sapiens? In this bold and provocative audiobook, Yuval Noah Harari explores who we are, how we got here, and where we're going.

An inspirational memoir of space exploration and hard-won wisdom, from an astronaut who has spent a lifetime making the impossible a reality. Colonel Chris Hadfield has spent decades training as an astronaut and has logged nearly 4,000 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, been temporarily blinded while clinging to the exterior of an orbiting spacecraft, and become a YouTube sensation with his performance of David Bowie's ‘Space Oddity' in space.

Bill Bryson has been an enormously popular author both for his travel books and for his books on the English language. Now, this beloved comic genius turns his attention to science. Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant.

In a rare blend of scientific insight and writing as elegant as the theories it explains, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.
