Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?

What actually happens when the words, "beam me up, Scottie" are uttered? What "warps" when something travels at warp speed? Internationally renowned theoretical physicist and educator Lawrence M. Krauss provides matter-of-fact scientific explanations of the physics of Star Trek in this highly creative and informative guide for both the devoted Trekkie and the physics novice.

On War was first published in 1832, at a time when muskets and cavalry were a dominating presence on the battlefield. Yet in the 21st century it remains a much-read and studied treatise on the subject – perhaps the most important European classic of its kind – and this despite the author’s demise before he could finish what was an extended review of the whole subject of military strategy. Why is that?

Experience Star Wars: A New Hope from a whole new point of view. On May 25, 1977, the world was introduced to Han Solo, Luke Skywalker, Princess Leia, C-3PO, R2-D2, Chewbacca, Obi-Wan Kenobi, Darth Vader, and a galaxy full of possibilities. In honor of the 40h anniversary, more than 40 contributors lend their vision to this retelling of Star Wars. Each of the 40 short stories reimagines a moment from the original film, but through the eyes of a supporting character.

Discover the science behind the most popular sci-fi franchise of all time. Capturing the imagination and hearts of crowds worldwide, Star Wars is a fantastic feat of science fiction and fantasy. We marvel at the variety of creatures and technology and the mystery behind the force. But how much of the Star Wars world is rooted in reality? Could we see some of the extraordinary inventions materialize in our world?

For the past four decades, no film saga has touched the world in the way that Star Wars has, capturing the imaginations of filmgoers and filmmakers alike. Now, for the first time ever, Edward Gross and Mark A. Altman, the best-selling authors of The Fifty-Year Mission, are telling the entire story of this blockbuster franchise from the very beginning in a single exhaustive volume.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us?

Stephen Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet - including climate change, the threat of nuclear war, and the development of artificial intelligence - he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

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.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

In Parallel Worlds, world-renowned physicist and best-selling author Michio Kaku - an author who "has a knack for bringing the most ethereal ideas down to earth" (Wall Street Journal) - takes listeners on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe.

Whether you are a scientist or a poet, pro-nuclear energy or staunch opponent, conspiracy theorist or pragmatist, James Mahaffey's books have served to open up the world of nuclear science like never before. With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.
