Stephen Hawking, the brilliant theoretical physicist, invites readers on an extraordinary journey through the universe in his book, The Universe in a Nutshell. This sequel to his multimillion-copy bestseller, A Brief History of Time, is a lavishly illustrated work that unravels the mysteries of the major breakthroughs in physics since the release of his first acclaimed book.

In this major publishing event, Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction. He explains in laymen’s terms the principles that control our universe, covering topics such as quantum mechanics, M-theory, general relativity, and superstrings. He guides us on his search to uncover the secrets of the universe—from supergravity to supersymmetry, and from holography to duality.

With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. The book is filled with copious four-color illustrations that help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions. Here, black holes evaporate and disappear, taking their secrets with them, and the original cosmic seed from which our universe sprang was a tiny nut.

The Universe in a Nutshell is essential reading for anyone who wants to understand the universe in which we live. It conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves, making it a must-read for all curious minds.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory.

In Hyperspace, Michio Kaku, author of the widely acclaimed Beyond Einstein and a leading theoretical physicist, offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics, work which includes research on the tenth dimension, time warps, black holes, and multiple universes.

The theory of hyperspace (or higher dimensional space)—and its newest wrinkle, superstring theory—stand at the center of this revolution, with adherents in every major research laboratory in the world, including several Nobel laureates. Beginning where Hawking's Brief History of Time left off, Kaku paints a vivid portrayal of the breakthroughs now rocking the physics establishment.

Why all the excitement? As the author points out, for over half a century, scientists have puzzled over why the basic forces of the cosmos—gravity, electromagnetism, and the strong and weak nuclear forces—require markedly different mathematical descriptions. But if we see these forces as vibrations in a higher dimensional space, their field equations suddenly fit together like pieces in a jigsaw puzzle, perfectly snug, in an elegant, astonishingly simple form.

This may thus be our leading candidate for the Theory of Everything. If so, it would be the crowning achievement of 2,000 years of scientific investigation into matter and its forces. Already, the theory has inspired several thousand research papers, and has been the focus of over 200 international conferences.

Michio Kaku is one of the leading pioneers in superstring theory and has been at the forefront of this revolution in modern physics. With Hyperspace, he has produced a book for general readers which conveys the vitality of the field and the excitement as scientists grapple with the meaning of space and time. It is an exhilarating look at physics today and an eye-opening glimpse into the ultimate nature of the universe.
