As a scientist, Albert Einstein is undoubtedly the most epic among 20th-century thinkers. Albert Einstein as a man, however, has been a much harder portrait to paint, and what we know of him as a husband, father, and friend is fragmentary at best. With Einstein: His Life and Universe, Walter Isaacson (author of the bestselling biographies Benjamin Franklin and Kissinger) brings Einstein's experience of life, love, and intellectual discovery into brilliant focus. The book is the first biography to tackle Einstein's enormous volume of personal correspondence that heretofore had been sealed from the public, and it's hard to imagine another book that could do such a richly textured and complicated life as Einstein's the same thoughtful justice. Isaacson is a master of the form and this latest opus is at once arresting and wonderfully revelatory. --Anne Bartholomew
Read "The Light-Beam Rider," the first chapter of Walter Isaacson's Einstein: His Life and Universe.
Five Questions for Walter Isaacson
Amazon.com: What kind of scientific education did you have to give yourself to be able to understand and explain Einstein's ideas?
Isaacson: I've always loved science, and I had a group of great physicists--such as Brian Greene, Lawrence Krauss, and Murray Gell-Mann--who tutored me, helped me learn the physics, and checked various versions of my book. I also learned the tensor calculus underlying general relativity, but tried to avoid spending too much time on it in the book. I wanted to capture the imaginative beauty of Einstein's scientific leaps, but I hope folks who want to delve more deeply into the science will read Einstein books by such scientists as Abraham Pais, Jeremy Bernstein, Brian Greene, and others.
Amazon.com: That Einstein was a clerk in the Swiss Patent Office when he revolutionized our understanding of the physical world has often been treated as ironic or even absurd. But you argue that in many ways his time there fostered his discoveries. Could you explain?
Isaacson: I think he was lucky to be at the patent office rather than serving as an acolyte in the academy trying to please senior professors and teach the conventional wisdom. As a patent examiner, he got to visualize the physical realities underlying scientific concepts. He had a boss who told him to question every premise and assumption. And as Peter Galison shows in Einstein's Clocks, Poincare's Maps, many of the patent applications involved synchronizing clocks using signals that traveled at the speed of light. So with his office-mate Michele Besso as a sounding board, he was primed to make the leap to special relativity.
Amazon.com: That time in the patent office makes him sound far more like a practical scientist and tinkerer than the usual image of the wild-haired professor, and more like your previous biographical subject, the multitalented but eminently earthly Benjamin Franklin. Did you see connections between them?
Isaacson: I like writing about creativity, and that's what Franklin and Einstein shared. They also had great curiosity and imagination. But Franklin was a more practical man who was not very theoretical, and Einstein was the opposite in that regard.
Amazon.com: Of the many legends that have accumulated around Einstein, what did you find to be least true? Most true?
Isaacson: The least true legend is that he failed math as a schoolboy. He was actually great in math, because he could visualize equations. He knew they were nature's brushstrokes for painting her wonders. For example, he could look at Maxwell's equations and marvel at what it would be like to ride alongside a light wave, and he could look at Max Planck's equations about radiation and realize that Planck's constant meant that light was a particle as well as a wave. The most true legend is how rebellious and defiant of authority he was. You see it in his politics, his personal life, and his science.
Amazon.com: At Time and CNN and the Aspen Institute, you've worked with many of the leading thinkers and leaders of the day. Now that you've had the chance to get to know Einstein so well, did he remind you of anyone from our day who shares at least some of his remarkable qualities?
Isaacson: There are many creative scientists, most notably Stephen Hawking, who wrote the essay on Einstein as "Person of the Century" when I was editor of Time. In the world of technology, Steve Jobs has the same creative imagination and ability to think differently that distinguished Einstein, and Bill Gates has the same intellectual intensity. I wish I knew politicians who had the creativity and human instincts of Einstein, or for that matter the wise feel for our common values of Benjamin Franklin.

Book Description
By the author of the acclaimed bestseller Benjamin Franklin, this is the first full biography of Albert Einstein since all of his papers have become available.
How did his mind work? What made him a genius? Isaacson's biography shows how his scientific imagination sprang from the rebellious nature of his personality. His fascinating story is a testament to the connection between creativity and freedom.
Based on newly released personal letters of Einstein, this book explores how an imaginative, impertinent patent clerk -- a struggling father in a difficult marriage who couldn't get a teaching job or a doctorate -- became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom and the universe. His success came from questioning conventional wisdom and marveling at mysteries that struck others as mundane. This led him to embrace a morality and politics based on respect for free minds, free spirits, and free individuals.
These traits are just as vital for this new century of globalization, in which our success will depend on our creativity, as they were for the beginning of the last century, when Einstein helped usher in the modern age.

A well orchestrated mix of personal history and revolutionary scientific discovery.......2007-10-09
A story of amazing power of reason in Einstein's early years but in the later years a sad story of his reason being foiled by of all things, scientific observations ("spooky" ones to be sure). When he died Einstein was still struggling with the idea that..."The reasonable thing just doesn't work.".
Excellent!.......2007-10-09
Excellently written and researched book. Very fascinating and engaging.
Even the scientific discussions were easy to understand.
I highly recommend this book.
A Must Read.......2007-10-07
A wonderful book which gives full and equal weight to both the man and the ideas which made him great, as well as the lasting place of those ideas in the history of scientific thought, if not of human thought itself. And on that latter point, the reader's debt to Isaacson is undoubtedly primarily for his continuing emphasis on Einstein's modus operandi: thought experiments, by which through the exercise merely of pure thought and a perspective unhampered by received wisdoms, a man was able to change millennia-old views of how we viewed the universe, and by extension, changed the universe itself. Whose thinking could remain uninfluenced by such a display of the power of thought?
Absolutely Fantastic.......2007-10-03
This biography reads like a story, creating suspense and other emotions that you experince while reading fiction. Einstein provides great insight into Einstein's mind and life. Highly recommended.

New Book that was NOT a new Book.......2007-06-08
Simply put - I purchased this Astronomy book through Amazon because the price was the same as elsewhere but I would save on shipping. I expected a NEW book but received a Used Book in good condition.
The Book itself so far seems well laid out and interesting but the course I am taking has just reached the 1/3 mark toward completion.
For the Non-Science Major.......2007-03-08
This book is designed to be the astronomy book that non-science majors would use to meet their one-year of science requirement as part of their undergraduate degree. As such it is written without the mathematics content that would be normal in a course aimed at astronoly or physics students. In addition, this particular book has several advantages. To identify just a few:
1. Throughout the book there is an emphasis on teaching the scientific method. This area has been strengthened in this edition because (I'm guessing) the current attempts by the un-intelligent design people to disparage scientific theories.
2. Revised to include the latest discoveries being made by the Mars rovers and the down grading of poor Pluto to a minor planet.
3. Updating the current theories regarding dark matter and dark energy.
In summary this is a well written, well illustrated text, ideally suited for the non-scientists.
Astronomy Today 5th edition.......2006-03-11
I have had a lifetime love of Astronomy but have lacked the mathmatical background for a thorough understanding. Most popular books on the subject rarely cover the field in the manner that I desire. Astronomy Today is a textbook for a beginning course in astronomy at the college level and does, in fact, cover a great deal of information without the need for mathmatical knowledge. The authors express their ideas and information in clear, concise language and clearly manifest an enthusiasm for their subject. I have enjoyed the book immensely.
A Paradox of Blind Astronomers!.......2005-06-23
This is an excellent textbook, but I deducted one star (from a possible five-star rating) because of the absurd comments made by the authors in the beginning of the book. In this fourth edition of Astronomy Today, a textbook published by Prentice Hall for college students, the authors open the very first chapter with the following statements:
"Of all the scientific insights attained to date, one stands out boldly: Earth is neither central nor special. We inhabit no unique place in the universe. Astronomical research, especially within the past few decades, strongly suggests that we live on what seems to be an ordinary rocky planet called Earth, one of the nine known planets orbiting an average star called the Sun, a star near the edge of a huge collection of stars called the Milky Way Galaxy, which is one galaxy among countless billions of others spread throughout the observable universe."
Huh!? Earth isn't special? Compare the other planets in our Solar System to Earth and tell us it isn't special. And Earth is "...an ordinary rocky planet..."? It's the only planet we know of with vast oceans of liquid water, a breathable atmosphere, lush vegetation, and a spectacular collection of life forms. The authors of this textbook must have been "out to lunch" when they wrote that trite introduction, or... this is just another deliberate attempt by "philosophers of gobbledygook" to strip the Earth of its special place in the universe and to squash any special characteristics that may differentiate it from everything else in the cosmos. I strongly suspect the latter viewpoint is the correct one.
The fact is the Earth is indeed a very special place, and the Sun is a very special star. In fact, the Sun-Earth relationship represents a very special arrangement that permits life to thrive upon our planet. Mercury, Venus and Mars may be nothing more than ordinary rocky planets, but Earth is truly unique from all the other planets in our Solar System, and may be truly unique in all the universe.
I stand by my initial rating of the textbook: 4 stars and an excellent read. I just have a wee bit of a problem with blind astronomers.
A joy to read!.......2005-02-18
This book is really outstanding! It contains 757 pages of text (not counting the preface and appendix), about 480 (mostly quite smallish) photos, some 400 drawings/figures/illustrations and almost 50 tables. The writing style is very clear, not at all dry or overtly technical. It is a joy to read this book. I know of no other book that clarifies all kind of astronomical subjects as thoroughly and understandably as this book (and I did read many books on astronomy.....). Highly recommended!
Book Description
A brief, introductory astronomy book designed for readers with little or no scientific background, A Beginner's Guide uses an exceptionally clear writing style. The authors present a broad view of astronomy without complex mathematics, yet the book discusses important concepts without simplification. The book's organization follows the popular and effective “Earth-Out” progression, starting with our planet and then moving through the solar system. A study of the Sun as a model star follows, then the book covers the Milky Way Galaxy, cosmology, and the universe as a whole. Because of its easy-to-read yet comprehensive coverage of astronomy, this book can serve as excellent reference material for those readers interested in learning about our universe.

Solid Intro Astronomy Book.......2007-03-28
This textbook presents information about the Earth, solar system, and universe in a clear manner that avoids technical jargon while staying scientifically respectable. The author demonstrates the practical uses of mathematics throughout the book and the end of chapter questions challenge the reader's grasp of the material. It's a rarity for such a readable book to be written by a person with this author's impressive educational creditials. I would definitely recommend this text and any other written by Chaisson.

Great Textbook.......2001-03-01
For anyone who has a vague interest in astronomy, this would be the book to read. Albeit not entirely simple, this is a relatively straight forward book that uses excellent examples to explain difficult concepts. There are many charts and diagrams. How exactly does a black hole work? What's the difference between a nova and a supernova (not as simple as you might think)? Why do we get meteor showers? There is a bit of mathematics involved, but nothing too intimidating. This is an excellent textbook. Best of all, a CD-ROM is included with lots of multimedia content, study questions, and links to more sources. Avoid other dry textbooks and purchase this one.
Book Description
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.

Half confused, half amazed.......2007-09-20
For as simple as Hawking was supposed to present the complicated theoretical physics concepts, at times I still found myself as confused as Adam on Mother's Day. Dr. Hawking's work is caught between a rock and a hard place in "A Brief History of Time" and the subsequent "The Universe in a Nutshell"; he provides neither the technical language to satisfy the experienced readers, nor the sufficiently simplified rhetoric to appeal to the uninitiated. Not to worry as the theories and supporting arguments in both books can still satisfy the curiosity of the inexperienced, and his celebrity status in the world of physics keeps the experienced audience engaged.
There is one update to this book not mentioned, and that is, Hawking eventually admits that he was wrong about his theory of loss of information in black holes. This idea of his had put him at odds with many theoretical physicists. Instead, he puts forth the unproven theory that information in a black hole is transferred to a parallel universe. Unfortunately, time may not permit Hawking to complete his work on the proof or supporting evidence of this important theory. His terminal illness appears to be finally catching up to him. I wish him well and thank him for his important contributions to the science of understanding the universe.
Despite its shortcomings, A Brief History of Time succeeds in shedding light on the mysteries of the creation of the universe at the point of singularity, what happened subsequently, and what may or may not transpire in the future. Hawking discusses in length Einstein's general theory of relativity, quantum mechanics and the attempt to combine these into a grand unified theory, a lofty goal that has eluded theoretical physicists to date.
Fascinating.......2007-09-17
Quite accessible for a book on the beginning of the universe. It doesn't explain how it got here, but begins at 1 second post big bang. It has a good explanation of the work of Isaac Newton and why it was important and also the work of Einstein. I understood the physics, at least I did when I was reading it. The explanations were good enough to let me wrap my mind around them. It is interesting that the idea of ether is coming back up for consideration again. Not sure I believe in string theory though. Why not just say everything is made of energy?
Hawking :a master writer.......2007-09-02
Hawking's new book "The Briefest History of Time" should be read by all intelligent Americans. Every book of this quality and with a similar contents may help to stop the tide of idiocy proposed by supporters of creationism in America.Only by spreading real science we will escape becoming the richest but also the most primitive intellectually nation in the world. We need a heavy counterweight to the evangelic snake oil peddlers who can gather tousands sing along automata and preach bible which offenses every educated and intelligent mind. Hawking's book can help to be such a counterbalance.

This book explains the physical concepts in very understandable fashion. It can be understood by any person. You do not have to be a scientist or physicists to read the book. There are also wonderful examples explaining the scientific phenomenon underlying our universe and black hole or other galaxies.

Book arrived in timely fashion, excellent condition, well packaged to protect it during shipment. I'd read it in the library and thought it excellent. I'm a logical person but not a physicist or a mathematician yet the material was understandable, well presented and the illustrations very helpful. The absence of long proofs/equations not only shortened the book but made the descriptions and illustrations easier to follow and not so intimidating. The large print version was especially helpful even though my eye sight is good. I'll read it a number of times and I'm sure my understanding will increase with each reading.

If Albert Einstein were alive, he would have a copy of The Road to Reality on his bookshelf. So would Isaac Newton. This may be the most complete mathematical explanation of the universe yet published, and Roger Penrose richly deserves the accolades he will receive for it. That said, let us be perfectly clear: this is not an easy book to read. The number of people in the world who can understand everything in it could probably take a taxi together to Penrose's next lecture. Still, math-friendly readers looking for a substantial and possibly even thrillingly difficult intellectual experience should pick up a copy (carefully--it's over a thousand pages long and weighs nearly 4 pounds) and start at the beginning, where Penrose sets out his purpose: to describe "the search for the underlying principles that govern the behavior of our universe." Beginning with the deceptively simple geometry of Pythagoras and the Greeks, Penrose guides readers through the fundamentals--the incontrovertible bricks that hold up the fanciful mathematical structures of later chapters. From such theoretical delights as complex-number calculus, Riemann surfaces, and Clifford bundles, the tour takes us quickly on to the nature of spacetime. The bulk of the book is then devoted to quantum physics, cosmological theories (including Penrose's favored ideas about string theory and universal inflation), and what we know about how the universe is held together. For physicists, mathematicians, and advanced students, The Road to Reality is an essential field guide to the universe. For enthusiastic amateurs, the book is a project to tackle a bit at a time, one with unimaginable intellectual rewards. --Therese Littleton
Book Description
Roger Penrose, one of the most accomplished scientists of our time, presents the only comprehensive and comprehensible account of the physics of the universe. From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

Sir Roger is as Confused as the Rest of Us.......2007-08-15
Roger Penrose feels comfortable in his Platonic mathematical world and he recognizes how useful complex analysis is to quantum theory. But, like everyone else, he is at a loss to explain things just when they become interesting.
He cannot explain to his own satisfaction how that the universe came to be so specially ordered at the moment of the big bang. He cannot explain in a mathematically elegant way how or why that the wave function collapses upon an observation being made, with a new wave function being thus created. He seems mystified by complex numbers in a way that is reminds one of Pythagoras. He speaks in a gushy way about how "magical" they are. Nevertheless, he cannot even be sure that perfect circles or pi or straight lines exist in reality. He is Platonic, despite modern philosophy's rejection of Plato's theory of forms. He gingerly avoids any metaphysics and/or religion. And, he feels that one can learn about our universe by studying pristine mathematical models, despite the fact that R. Feynman and others have said that the only road to truth (the real road to reality) is through experimentation. Feynman wisely stated that he could calculate things very precisely, but he could not explain things in common sense, everyday terms. Are we really going to do better than him?
Perhaps things are as one physicist said " ..not only strange, but stranger than we can contemplate". We are physically not equipped to explain things.
A book with a message.......2007-07-11
Other reviews focus on whether the book is easy to understand or not, or wheter it is too big or not. And it would seem that
the only purpose of the book is to put all togheter the physical laws mankind knows.
But this is a book with a message. A message that takes very long to transmit and Penrose chose to start from the very begining.
A significant part of the physics as it is known today is exposed in a long (900 pages) preamble, but Penrose wants to tell
us that he believes that the road to the Theory of Everything that is standard in today's physics leads nowhere.
If you have read "The Emperor's new mind" you know that Penrose's ideas are not mainstream in today's physics. But if you are
interested in cutting edge physics you'll also know that there is a growing number of physicists that believe that the field is on crisis. Let me sumarize Penrose views:
- The standard interpretations of quantum mechanics are wrong. Even the decoherence approach.
- Infactionary cosmology cannot be right.
- Superstring theory is just a beautiful mathematical construction with no connection to the physical world. His point of view is similar to Smolin's ("The trouble with physics").
I'm not at all an expert on the field, although I studied quantum mechanics in the University, and I'd say that at least Penrose has a very strong point. He is not able to provide but hints of alternative theories but this does not lower the merit of the book.
He also explains standard areas of mathematics and physics such as complex number calculus, Maxwell fields or group theory in a non-conventional but brilliant way. For example, it includes a beautiful demonstration of Pythagoream theorem. The chapter about the standard model of particle physics is particularly helpful; nowhere else can be found a concise and understable explanation of it.
And yes, the book is difficult, but if you don't understand the mathematics, just keep reading.

There is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that the two pillars of physics can be reconciled in superstring theory, a theory of everything.
Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all worked out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate.
Though Ed Witten of the Institute for Advanced Study is in many ways the human hero of The Elegant Universe, it is not a human-side-of-physics story. Greene's focus throughout is the science, and he gives the nonspecialist at least an illusion of understanding--or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge. --Mary Ellen Curtin
Book Description
"[Greene] develops one fresh new insight after another...In the great tradition of physicists writing for the masses,
The Elegant Universe sets a standard that will be hard to beat." --George Johnson, The New York Times Book Review
In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.
Green uses everything from an amusement park ride to ants on a garden hose to illustrate the beautiful yet bizarre realities that modern physics is unveiling. Dazzling in its brilliance, unprecedented in its ability to both illuminate and entertain,
The Elegant Universe is a tour de force of science writing-a delightful, lucid voyage through modern physics that brings us closer than ever to understanding how the universe works.

Anyone who is curious about the horizons of theoretical physics will enjoy this book.......2007-08-30
In this brilliantty articulated and refreshingly clear book, Greene, a leading string theorist, relates the scientific story and the human struggle behind the search for the ultimate theory. String theory, as the author vividly and easily describes, reveals a vision of the universe that is sending shock waves through the world of physics. Thrilling and revolutionary ideas such as new dimensions hidden within the fabric of space, black holes transmuting into elementary particles, rips and puncutures in the space time continuum, gigantic universes interchangealbe with minusclule ones, and a wealth of others are playing a pivotal role as physicists use string theory to grapple with some of the deepest questions of the ages.
Almost 5 Stars.......2007-07-19
Although I felt this book was excellent and covered all the bases there were a few areas that lacked for me and I couldn't quite give it 5 stars. The book started out phenomenally and the section on quantum mechanics was the best that I've read. The analogies that Mr. Greene used made the concepts clear and comprehendable but there were a few chapters in the middle where he used no analogies and I found myself completely lost even after re-reading the chapters. I might be too much of a layman for this book and that would certainly not be Mr. Greene's fault. There were additional parts of the book where I found myself easily destracted and those chapters were almost a chore to finish. Over all I think parts of this book are great for readers who are just begining to study this subject but other whole chapters are definately not.

science or science fiction? .......2007-07-08
"Theoretical physicist is the one whose experiments don't work".
So says my friend, an engineer by profession, and The Elegant Universe fully confirms this view - more, since we learn that the theories of modern physics are beyond our technological ability to test them experimentally.
The theories themselves are indeed very elegant, composed with great care for estetics and symmetry, and well illustrated by pictures. Nonetheless, we are left with an impression that most of it is the stuff of phantasy, and just as one calculation will "prove" some idea, another set of equations will "disprove" it with identical claim to "scientific truth". I've put all this terms in quotes because the maybe factor of all proofs is too strong to take the presented theories seriously. The author admits that all the calculations are based on approximations and numerous assumptions, raising from still more approximations and probabilities. And when the result is absurd, the theorists quickly solve the problem by inventing one more spatial dimention, not accessible to our perceptions because it never expanded from its initial state.
Actually, the whole string theory deals with aspects of reality not accessible to our perceptions, and not provable by any experiments. Is it still reality or already a fiction? We don't know, and chances are will never know.
With all this, it is indeed an extremely elegant text, beautifully written and holding our attention all the way to the end. I just wish the author did not say all of the time that string theory had been "discovered", since for all we know theories are not material reality, such as a continent of America or a rare species of a butterfly, and so they cannot be discovered, theories can only be conceived, invented, or created. This lexical misuse is eye-catching due to the prevalence of hypotheses over the facts so stronly visible in string theory.
Crackling and sizzling ! - This one requires some attention and tenacity though........2007-06-27
A good book which covers the below topics
1) Requirement of single physical law which brings together all the four fundamental forces: Electromagnetic, Strong nuclear, weak nuclear and gravity.
2) Disparity between theory of relatively (the world of the big) with quantum mechanics (world of the very small)
2) The need of a higher theory to explain the standard model (Explanation for the disparate mass and charges of the subatomic particles)
3) The concept of 11 dimensional space; Mass and charge of the numerous particles found in atom smashers being a result of frequency of vibrations of strings (closed or open) in different dimensions. Meaning a string vibrating with a certain frequency along one of the hidden 7 pinched up spatial dimensions (also termed calabi Yau spaces) will represent a subatomic particle
4) Membrane theory (2 branes, 3 branes etc)
5) M theory unifying the 5 known strings theories (by the addition of another spatial dimension)
6) Thus everything in this universe including the keyboard you are right now typing on is made up of tiny vibrating strings and below this level there is nothing. A string would be the last divisible entity beyond which it is not possible to divide anymore.
Basically everthing stripped down to strings. This is a book for the reader who doesn't know anything about string theory but wants to learn something. As a general reader, you are not in a position to take a stand for or against string theory, because the person picking up this book will be layman and hence rightly there are no equations, so you have to accept things at face value. If you were more deeply interested you would be a physicist doing his PHD and hence will read more dense and technical books as college courses.
But as a layman, you will also appreciate the paucity of physical evidence to support string theory. Particle physicists consider it the right theory because of its mathematical elegance in it's equations. As a layman, you and I are not able to see this elgance as we dont read equations. So I cant form a real opinion about this but I can say that this book will provide the uninitiated a quick cursory primer on string theory with the help of analogies. But this book wont make you believe or disbelieve string theory but you will become more aquainted with what this hype is all about.

Stephen Hawking, one of the most brilliant theoretical physicists in history, wrote the modern classic A Brief History of Time to help nonscientists understand the questions being asked by scientists today: Where did the universe come from? How and why did it begin? Will it come to an end, and if so, how? Hawking attempts to reveal these questions (and where we're looking for answers) using a minimum of technical jargon. Among the topics gracefully covered are gravity, black holes, the Big Bang, the nature of time, and physicists' search for a grand unifying theory. This is deep science; these concepts are so vast (or so tiny) as to cause vertigo while reading, and one can't help but marvel at Hawking's ability to synthesize this difficult subject for people not used to thinking about things like alternate dimensions. The journey is certainly worth taking, for, as Hawking says, the reward of understanding the universe may be a glimpse of "the mind of God." --Therese Littleton
Book Description
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.

This book is a fake!.......2007-10-01
As a physicist I am flabbergasted and slightly depressed by the success of this book. First of all this book presents as if they were equally certain some pieces of orthodox science together with some of the author's dubious speculations. The lay reader is not told which are which. Secondly, the author obviously has no knowledge of the actual history of physics and yet he shamelessly "describes" it to the reader.
Hawking seems to have gathered together all the bad cliches about various physical issues and has taken out all the valuable ideas. He explains nothing, he just asserts that "we physicists know that..., we physicists have demonstrated that...". I cannot see how anyone can actually learn anything about physics from this book, about why we know what we know. And yet, judging from the amount of praise this book receives, it seems that quite a lot of people have fallen under the spell that they have been allowed access to some secret. They haven't and I find this trickery immoral.
Quantum physics and astrophysics are really interesting. They don't deserve to be thrashed in this unashamed manner. If you want to learn something about physics, there are other books which do a much better job, for example Asimov's Atom: Journey Across the Subatomic Cosmos.
Author - a true genius.......2007-09-22
Stephen Hawking is a true genius. Although I don't understand everything he writes, all-in-all this book gives one the understanding of how wonderfully made the universe is.
Fascinating.......2007-08-24
I found this book to be ingenious yet accessible to the average reader, which is what I believe Hawking set out to accomplish. Great food for thought in my opinion.
TERRIBLE digital transfer by "Phoenix Audio".......2007-08-10
It's a great book by Hawking, but this product is just a reproduction of something by Hawking/Jackson that we already know is great. So what sort of job does this product do of delivering one of my favorite audio books? Not a very good one.
The original recording sounds fine, but this production from 2005 sounds like it was converted to a low bit rate at some point during editing, and probably had a poor noise removal job done as well. For the benefit of removing possibly a little weak static in the background, we get to listen to a robotic Jackson for 5 hours. It sounds similar to an early digital cell phone with a choppy feel and many T's and S's muffled.
There really isn't any reason I can see for this to not be a perfect reproduction of earlier digital versions. Old bootlegs floating about the internet sound better. Maybe "Phoenix Audio" should have just grabbed those to print, and left all of that tricky audio work to the more competent civilian sector.
A well written classic.......2007-08-01
I have a stack of these :The First Three Minutes: A Modern View of the Origin of the Universe,Cosmic Code and In Search/big Bang: /, so I can compare and contrast.
There is material on black holes here that isn't covered as well in the others. I still would wish that all these authors would put in more of the real equations and less of the dumbing down. One point is that people not able to understand this kind of book, probably won't understand no matter how simple you make the text. Maybe one should make effective use of your time in writing and concentrate on those who will understand and use the results.
Book Description
Introduction to Cosmology provides a rare combination of a solid foundation of the core physical concepts of cosmology and the most recent astronomical observations. The book is designed for advanced undergraduates or beginning graduate students and assumes no prior knowledge of general relativity. An emphasis is placed on developing the readers' physical insight rather than losing them with complex math. An approachable writing style and wealth of fresh and imaginative analogies from "everyday" physics are used to make the concepts of cosmology more accessible. The book is unique in that it not only includes recent major developments in cosmology, like the cosmological constant and accelerating universe, but also anticipates key developments expected in the next few years, such as detailed results on the cosmic microwave background. For anyone interested in cosmology or astronomy.

Ease your way into cosmology.......2005-09-06
As an undergraduate studying particle physics, I have found Ryden to be an excellent first-book in cosmology for self-study. The text requires no previous knowledge of general relativity (though this certainly helps, perhaps at the level of Carroll's text) or astrophysics, which is refreshing for those who would rather not wade through the astrophysics part of an astrophysics-cosmology course.
Ryden's explanations are clear and carefully thought out, and she really makes an effort to hold one's hand through many topics. The book is straightforward and well-organized enough for more advanced students to skim quickly through chapters they are familiar with while also being able to slow down at certain points for a careful derivation here and there.
Overall, the topics are somewhat rudimentary (this text is definitely geared towards undergraduates)--i.e. don't expect to be calculating dark matter relic densities or studying cosmic strings--but combined with her suggested references for further reading and the text's ground-up style, this is a fantastic book at this level that provides a solid foundation for students who wish to move on to more advanced texts such as Kolb and Turner or Dodelson.
Addison Wesley should also be commended for their excellent typesetting (continuing a string of very well typeset books including Carroll's Spacetime Geometry and Goldstein's Classical Mechanics, 3rd. ed). Formulae are clear and easy to read, sections are well divided, and there is a wonderfully large margin for readers to write notes in.
The only lament I can agree with on this book is that it does not contain WMAP data, which would be a delight for a modern cosmology book.
Very well written.......2004-11-15
It seems lately people have been writing very good textbooks, for example "Gravity: from the ground up", "String theory: First Course" and "Spacetime and Geometry" etc, and this is among the best. As has been mentioned, there are no tensors in this book. General relativity is introduced with equivalence principle and the metric and by investigating different kind of curvatures and corresponding metrics. Clarity is outstanding in almost every chapter.
After introducing the Friedmann, fluid and acceleration equations etc, the chapters include single-component universes, multiple-component universes, measuring cosmological parameters. dark matter, cosmic microwave background, nucleosynthesis and the early universe, inflation and the very early universe + formation of structure. I think one of the positives of this book is that the chapters are quite short and the whole book itself is quite short at 250 pages. I think this is a good thing because its much easier to stay focused/motivated when you know it wont take 10 years to reach the end. And as has been mentioned, the writing style is very understandable and not too terse. I think this book is a perfect example on how to write physics tetxbooks.
Clear and useful.......2003-02-06
This book is an excellent introduction to all facets of cosmology for anyone from advanced undergraduates on. It includes a slow immersion in the key physical concepts of current cosmology theory, and broadly covers all relevent topics, as listed in the chapter headings. However, the greatest strength of this book is in the decision to forgo detailed General Relativity derivations. Instead of pages of numbing treatment of tensor math and metrics, Ryden summarizes the results of GR that are relevant to current cosmology, presenting the Friedmann equation and the Robertson-Walker metric. While this approach might infuriate purists, it allows the student to understand cosmology from a conceptual standpoint, while providing the mathematical tools necessary for analysis, and is a sufficient general introduction for any physics or astronomy student. It also provides a strong base of knowledge for those who do wish to proceed further into the details of GR. Furthermore, the conversational style of the text makes it much easier to read than any other physics textbook I have encountered. I would recommend any student (or professional) who slogged through their cosmology studies with no sense of the overall state of the field to use this book for both brushing up on the basics and as a quick reference.
Book Description
This important textbook is based on, though independent of, an educational TV series to be broadcast on public television in the United States. Its aim is to guide students and general readers to an understanding of how the physical world works; physics is presented as a human endeavour, with historical development forming a thread throughout the text. The prerequisites are minimal, only basic algebra and trigonometry since the necessary calculus is developed in the text, with physics providing the motivation. New concepts are introduced at the natural, logical point with many historical references to place physics in a social perspective. Many topics from twentieth-century physics are included, for example energy, low temperature physics, relativity and black holes. The book is attractively and profusely illustrated and will be welcomed by students and also by general readers for whom this will be a stimulating alternative to other, less-thorough treatments.
Book Description
This is an outstanding text with a long history that has been updated and given a fresh look, including worked examples pulled out of the text into numbered boxes. The text is now also accompanied by stronger media support with "CPS" eInstruction student response system questions, more extensive online quizzing, and PowerPoint lectures. Aimed at presenting the essentials of physics, chemistry, earth science, and astronomy in a clear, easy-to-understand way, The Physical Universe shows students how science works, how scientists approach problems, and why science constantly evolves in its search for understanding. The text can also be packaged with its long time companion student study guide, which includes a review of chapter terms and concepts; self quizzing for extra practice; and solved problems from the text.

Creationism vs. evolution.......2007-06-05
If you believe in creationism then read this book with caution. This book tries to brainwash you into thinking that evolution is based on solid foundation and creationism is quack. Buyer beware. I would not buy this book for someone under 18 years of age.
Very Easy Book To Read.......2006-02-25
This book is self explanatory and easy to read. I use this book for my SC 102 class. I'm a senior non-science major and it is really a good book.
Very good book and CD.......2005-09-24
The book is very good and the merchant was excellent in service and delivery.
Nice edition, but it is really necessary?.......2004-04-16
For over thirty years, McGraw has been putting out various editions of this highly successful textbook. Now in its tenth iteration, McGraw has made an important extension. It added a CD (which was long overdue). Plus, the book gives access to an online resource called PowerWeb. Pretty snazzy! You can access whole bunches of material there which is simply not in the book.
Hopefully, this may help motivate some students to learn more effectively. But a disquieting counterargument has arisen in some quarters. Is a new edition really needed? Perhaps an earlier edition would suffice for most students. If so, this would let several buy second hand versions far more cheaply. But if the publisher goes to this edition, and it is made mandatory by a school, then it is far harder for students to find used versions. At least for a few years. And later? When those used editions start circulating, what if the publisher and school then go to a newer edition?
From the Viewpoint of a Freshman High School Student........1998-11-30
This title is a comprehensive look at many aspects of science. Its Study guide is very helpful in preparing for examinations. The book, however, has a complicated way of explaining material. This slight defect may be reduced with the help of the useful appendixes, and study guides.
