This new edition of the acclaimed bestseller is lavishly illustrated to convey, in pictures as in words, Bill Bryson’s exciting, informative journey into the world of science.
In A Short History of Nearly Everything, the bestselling author of A Walk in the Woods and The Body, confronts his greatest challenge yet: to understand—and, if possible, answer—the oldest, biggest questions we have posed about the universe and ourselves. Taking as his territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. The result is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Now, in this handsome new edition, Bill Bryson’s words are supplemented by full-color artwork that explains in visual terms the concepts and wonder of science, at the same time giving face to the major players in the world of scientific study. Eloquently and entertainingly described, as well as richly illustrated, science has never been more involving or entertaining.

Chapter One
1 HOW TO BUILD A UNIVERSE
NO MATTER HOW hard you try you will never be able to grasp just how tiny, how spatially unassuming, is a proton. It is just way too small.
A proton is an infinitesimal part of an atom, which is itself of course an insubstantial thing. Protons are so small that a little dib of ink like the dot on this i can hold something in the region of 500,000,000,000 of them, rather more than the number of seconds contained in half a million years. So protons are exceedingly microscopic, to say the very least.
Now imagine if you can (and of course you can't) shrinking one of those protons down to a billionth of its normal size into a space so small that it would make a proton look enormous. Now pack into that tiny, tiny space about an ounce of matter. Excellent. You are ready to start a universe.
I'm assuming of course that you wish to build an inflationary universe. If you'd prefer instead to build a more old-fashioned, standard Big Bang universe, you'll need additional materials. In fact, you will need to gather up everything there is—every last mote and particle of matter between here and the edge of creation—and squeeze it into a spot so infinitesimally compact that it has no dimensions at all. It is known as a singularity.
In either case, get ready for a really big bang. Naturally, you will wish to retire to a safe place to observe the spectacle. Unfortunately, there is nowhere to retire to because outside the singularity there is no where. When the universe begins to expand, it won't be spreading out to fill a larger emptiness. The only space that exists is the space it creates as it goes.
It is natural but wrong to visualize the singularity as a kind of pregnant dot hanging in a dark, boundless void. But there is no space, no darkness. The singularity has no "around" around it. There is no space for it to occupy, no place for it to be. We can't even ask how long it has been there—whether it has just lately popped into being, like a good idea, or whether it has been there forever, quietly awaiting the right moment. Time doesn't exist. There is no past for it to emerge from.
And so, from nothing, our universe begins.
In a single blinding pulse, a moment of glory much too swift and expansive for any form of words, the singularity assumes heavenly dimensions, space beyond conception. In the first lively second (a second that many cosmologists will devote careers to shaving into ever-finer wafers) is produced gravity and the other forces that govern physics. In less than a minute the universe is a million billion miles across and growing fast. There is a lot of heat now, ten billion degrees of it, enough to begin the nuclear reactions that create the lighter elements—principally hydrogen and helium, with a dash (about one atom in a hundred million) of lithium. In three minutes, 98 percent of all the matter there is or will ever be has been produced. We have a universe. It is a place of the most wondrous and gratifying possibility, and beautiful, too. And it was all done in about the time it takes to make a sandwich.
When this moment happened is a matter of some debate. Cosmologists have long argued over whether the moment of creation was 10 billion years ago or twice that or something in between. The consensus seems to be heading for a figure of about 13.7 billion years, but these things are notoriously difficult to measure, as we shall see further on. All that can really be said is that at some indeterminate point in the very distant past, for reasons unknown, there came the moment known to science as t = 0. We were on our way.
There is of course a great deal we don't know, and much...

المراجعات-
April 7, 2003 As the title suggests, bestselling author Bryson (In a Sunburned Country) sets out to put his irrepressible stamp on all things under the sun. As he states at the outset, this is a book about life, the universe and everything, from the Big Bang to the ascendancy of Homo sapiens. "This is a book about how it happened," the author writes. "In particular how we went from there being nothing at all to there being something, and then how a little of that something turned into us, and also what happened in between and since." What follows is a brick of a volume summarizing moments both great and curious in the history of science, covering already well-trod territory in the fields of cosmology, astronomy, paleontology, geology, chemistry, physics and so on. Bryson relies on some of the best material in the history of science to have come out in recent years. This is great for Bryson fans, who can encounter this material in its barest essence with the bonus of having it served up in Bryson's distinctive voice. But readers in the field will already have studied this information more in-depth in the originals and may find themselves questioning the point of a breakneck tour of the sciences that contributes nothing novel. Nevertheless, to read Bryson is to travel with a memoirist gifted with wry observation and keen insight that shed new light on things we mistake for commonplace. To accompany the author as he travels with the likes of Charles Darwin on the Beagle, Albert Einstein or Isaac Newton is a trip worth taking for most readers. First printing 110,000; 11-city author tour.
New York Times Book Review
"A modern classic of science writing. . . . The more I read of A Short History of Nearly Everything, the more I was convinced that Bryson had achieved exactly what he'd set out to do."
Seattle Times
"A highly readable mix of historical anecdotes, gee-whiz facts, adept summarization, and gleeful recounts of the eccentricities of great scientists. It moves so fast that it's science on a toboggan."
Boston Globe
"[Bill Bryson] makes science interesting and funny. . . . You can bet that many questions you have about the universe and the world will be answered here."
People
"Here are answers to the stupid questions you were afraid to ask in school . . . [Bryson] peppers the book with wit and great details. . . . Bottom line: Science with a smile."
Tim Flannery, Times Literary Supplement
"It is one of this book's great achievements that Bryson is able to weave a satisfying universal narrative without sparing the reader one whit of scientific ignorance or doubt. . . . [A Short History of Nearly Everything] represents a wonderful education, and all schools would be better places if it were the core science reader on the curriculum."
