Illustrated a Brief History of Time [Paperback]

This book covers ideas that are profound and affect everyone. It explains theories that concern the creation of the universe, time travel, light-speed travel, and many more topics. Imagine actually having some grasp of Einstein's general relativity. Ever heard of string theory? How might time travel actually be possible? What are these black holes of which I've heard? This book packs an incredible amount of information into its 248 pages, yet somehow is still easily read - this is the true marvel of this book.

The illustrated version is worth the extra money. It contains many updates and additions throughout the book by Hawking (including the time travel chapter!). Every (and I mean every) concept throughout the book is accompanied by at least one illustration - think about it: 240 color illustrations with only 248 pages!

Towards the middle of the book, some of the concepts get more complex (when he really gets into the details of sub-atomic particles). However, as a recent high school graduate, I can say with some level of certainty that the average person can understand 90% of this book - and those parts are the most interesting! It will change the way you look at the universe.

In this updated version, Hawking moves from time travel to black holes to general relativity, quantum mechanics and even string theory, he never fails to captivate and entrance, even though some of the theories are difficult to grasp.

The sections devoted to black holes and time travel are, in my view, the most interesting... putting a human slant of a highly theorical subject. With the addition of hundreds of amazing illustrations and photos, Hawking has made his revised book extremely readable and colorful, both comprehensive and comprehendable, as one reviewer put it.

An excellent introduction to relativity, big bang, and anything else you might have scratched your head about!

There aren't many who could have written this book, and that Hawking has done it in the grips of a stable but still cruel malady, Lou Gehrig's disease, is a testament to his will and mounting intellect. He almost manages to carry it off.

Probably this is no fault of his own. The subject matter is, in the hands of ordinary physicists, incredibly abstruse stuff. Scientific prose is fragile; one has to handle it carefully and reread it numerous times even to begin to understand it--and that only if one is an expert in the field. To try to translate that into ordinary English, so that we mortals might understand--that is when scientific writing becomes the calling of saints.

Add onto this task the incredible popularity of this book (it, or Cosmos, I forget which, is the best-selling non-religious book of all time) the first time it was published, and you can get a feeling for what Hawking was up against. He isn't just writing for the Scientific American crowd, but for the Parade crowd and the People crowd. This is populist science.

The *Illustrated History* improves on its predecessor in a number of respects. It expands on a number of explanations that were incomplete in the first edition. It adds a new section on developments that have occurred in the meantime. And of course there are those full-color pictures, where there was previously only black and white.

(Don't pooh-pooh the pictures. Never underestimate the lasting impression of a picture that the reader *understands*.)

But there are flaws. Small flaws, but flaws nonetheless. Hawking is an engaging writer (and even, despite the voice synthesizer he uses after an operation on his larynx, a passable speaker), but he does not quite have the flair for explanation of a Sagan or a Feynman. The analogies he uses are hardly original, but long-standing ones that have withstood the test of time, and they serve him well.

When he has to stand on his own, though, as he must when he explains his own concept of imaginary time, he seems less sure of his footing. It all seems quite simple upon first inspection, and yet, when you examine it closer, it doesn't totally make sense.

But this is a minor quibble. The book is an excellent introduction to cutting edge research in cosmology, and if Hawking is not a Carl Sagan or a Richard Feynman, that is hardly a knock on him. His work, in the end, will speak for itself.
