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 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.
STEPHEN HAWKING held the position of Lucasian Professor of Mathematics at the University of Cambridge for thirty years; his other books for the general reader include the essay collection Black Holes and Baby Universes and The Universe in a Nutshell. Physicist LEONARD MLODINOW, his collaborator for this new edition, has taught at Cal Tech, written for Star Trek: The Next Generation, and is the author of Euclid's Window and Feynman's Rainbow and the co-author of the children's book series The Kids of Einstein Elementary.
