A Briefer History Of Time

"A Brief History of Time, published in 1988, was a landmark volume in science writing and in world-wide acclaim and popularity, with more than 9 million copies in print globally. The original edition was on the cutting edge of what was then known about the origins and nature of the universe. But the ensuing years have seen extraordinary advances in the technology of observing both the micro- and the macrocosmic world--observations that have confirmed many of Hawking's theoretical predictions in the first edition of his book.
Now a decade later, this edition updates the chapters throughout to document those advances, and also includes an entirely new chapter on Wormholes and Time Travel and a new introduction. It make vividly clear why "A Brief History of Time has transformed our view of the universe.

Stephen Hawking's worldwide bestseller, A Brief History of Time, has been a landmark volume in scientific writing. Its author's engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book's most important concepts.
This is the origin of and the reason for A Briefer History of Time: its author's wish to make its content more accessible to readers--as well as to bring it up-to-date with the latest scientific observations and findings.
Although this book is literally somewhat "briefer," it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.
This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book--but even more so--A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space.
