The international bestseller that inspired a major Nova special and sparked a new understanding of the universe, now with a new preface and epilogue. Brian Greene, one of the world's leading string theorists, peels away layers of mystery to reveal a universe that consists of eleven 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.

The Elegant Universe makes some of the most sophisticated concepts ever contemplated accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

The Theory of Everything is based on a series of lectures given at Cambridge University by the renowned Professor Stephen Hawking. This work introduces the history of ideas about the universe along with today's most important scientific theories about time, space, and the cosmos in a clear, easy-to-understand way.

"The Theory of Everything" presents the most complex theories of physics, both past and present, in a manner that remains clear and accessible. It aims to enlighten readers and expose them to the rich history of scientific thought and the complexities of the universe in which we live.

Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher is a publishing first. This set couples a book containing the six easiest chapters from Richard P. Feynman's landmark work, Lectures on Physics—specifically designed for the general, non-scientist reader—with the actual recordings of the late, great physicist delivering the lectures on which the chapters are based.

Nobel Laureate Feynman gave these lectures just once, to a group of Caltech undergraduates in 1961 and 1962. These newly released recordings allow you to experience one of the Twentieth Century's greatest minds—as if you were right there in the classroom.
