A collection of essays discussing the philosophy and foundations of quantum gravity. Written by leading philosophers and physicists in the field, chapters cover the important conceptual questions in the search for a quantum theory of gravity, and the current state of understanding among philosophers and physicists.

So far as we know this is the first book to present the rock bottom connection between science and religion. And the interesting thing about it is that it is done from the basis of Einstein's equations of physics and geometry. For thousands of years we have been faced with the problem of understanding the relation between our physics and what underlies it. So far as we know this is the first time the solution has been in print. And it is simple and readable. We don't have two worlds one for the scientists and one for the mystics. There's only one of it. And if the mystics are right in their descriptions, and if the scientists are right in theirs, we need only a translator and a dictionary of both languages. Fortunately for us, John Dobson has lived and worked in both camps, and knows both languages, so he undertook the task of translating. But to succeed in joining the descriptions by the physicists and the mystics he had to start far below the scientist's descriptions and he got there through Einstein's 1905 equations, his physics and his geometry.

Are there more than four dimensions to physical reality?Is it possible to traverse time as well as space?Is there a reality beyond our traditional concepts of time and space? The startling discovery of modern science is that our physical universe is actually finite. Scientists now acknowledge that the universe had a beginning. They call the singularity from which it all began the "Big Bang." While the detail among the many variants of these theories remain quite controversial, the fact that there was a definite beginning has gained widespread agreement. This is, of course, what the Bible has maintained throughout its 66 books.

"If Ms. Frizzle were a physics student of Stephen Hawking, she might have written THE UNIVERSE IN YOUR HAND, a wild tour through the reaches of time and space, from the interior of a proton to the Big Bang to the rough suburbs of a black hole. It's friendly, excitable, erudite, and cosmic." —Jordan Ellenberg, New York Times besteselling author of How Not To Be Wrong Quantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of math. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph. Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way. Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field.

In his sci-fi epic Interstellar, Christopher Nolan takes on the infinite canvas of space to deliver a cutting-edge, emotionally charged adventure that will amaze audiences of all ages. Interstellar: Beyond Time and Space documents the making of Nolan's latest masterpiece in fascinating detail and features interviews with the acclaimed director, along with screenwriter Jonathan Nolan, producer Emma Thomas, and other key members of the production team. Delving into the science and philosophy behind the film, Interstellar: Beyond Time and Space dynamically showcases its incredible concept art, including costume designs, storyboards, and other fascinating preproduction elements. Also featuring interviews with the exceptional cast, including Matthew McConaughey and Anne Hathaway, Interstellar: Beyond Time and Space tells the full story of the making of the film, with candid pictures illustrating its elaborate set pieces and reliance on classic special effects techniques. Visually enthralling and engrossing in its in-depth exploration of the themes and ideas at the heart of Interstellar, this book is the perfect accompaniment to one of the most anticipated films of 2014. Based on the film from Warner Bros. Pictures and Paramount Pictures. From acclaimed filmmaker Christopher Nolan ("The Dark Knight" films, "Inception"), "Interstellar" stars Oscar winner Matthew McConaughey ("Dallas Buyers Club"), Oscar winner Anne Hathaway ("Les Misébles"), Oscar nominee Jessica Chastain ("Zero Dark Thirty"), Bill Irwin ("Rachel Getting Married"), Oscar winner Ellen Burstyn ("Alice Doesn't Live Here Anymore"), and Oscar winner Michael Caine ("The Cider House Rules"). The main cast also includes Wes Bentley, Casey Affleck, David Gyasi, Mackenzie Foy and Topher Grace. Christopher Nolan directed the film from a screenplay he co-wrote with Jonathan Nolan. Emma Thomas, Christopher Nolan and Lynda Obst produced "Interstellar," with Jordan Goldberg, Jake Myers, Kip Thorne and Thomas Tull serving as executive producers. Warner Bros. Pictures and Paramount Pictures present, in association with Legendary Pictures, a Syncopy/Lynda Obst Productions production, a film by Christopher Nolan, "Interstellar."
