Le XXe siècle a vu naître les deux plus belles théories physiques jamais inventées. La première, la relativité générale, est l'œuvre du seul Albert Einstein. Son domaine d'application est l'infiniment grand. La seconde, la mécanique quantique, est l'œuvre collective de certains des plus grands esprits du XXe siècle. Son domaine d'application est l'infiniment petit. Mais ce ...more

It is described very easily, actually. You will have to concentrate of course, but the examples are easy to understand.

He takes another route, if you want. He doesn't try to teach you math but to show you through easy every-day-examples the concepts behind Einstein, Standardmodell and String-Theory. (less)

[Original review, written December 2008]

When I read this book, I remember thinking it was pretty interesting, but I am surprised how few insights I have retained... to be honest, hardly any. Smolin's The Trouble with Physics, which I read much more recently, suggests that string theory is in big trouble, and right now I am more tempted to side with Smolin.

There's this old Nasrudin story, where he's somehow ended up as judge in a court case. The D.A. really makes a good case, and Nasrudin can't r

عندما سقطت التفاحة التوراتية سقطنا معها إلى هذا العالم و من ثم أصبح لزاما علينا أن نفهمه أو على الأقل نفهم كيف نعيش فيه. و عندما سقطت تفاحة نيوتن ظن العلماء أننا فهمنا أخيرا برغم مقولة نيوتن بأنه كشخص يلعب بالأصداف على شاطئ المحيط بدون أن يجرؤ حتى على النزول و معرفة ما فيه ناهيك عما وراءه.

فسر القانون العام للجاذبية حركة الكون و وضع لنا أول تصور غير اسطورى أو دينى للعالم من حولنا و ظل صالحا لكل الأحوال ما يربو على الثلاثة قرون إلى أن جاء اينشتين و لكن هذه المرة بدون تفاح بنظرية يصعب تذوقها و هضمه

Do I understand string theory? Not sure.

Do I understand M theory? A little bit but don't ask for any algebraic reasoning.

Do I know exactly what a Calabi-Yau is? Not really but I think they look a little like the hair balls from my cat.

This is the second time I've equated quantum physics and all its detours to a hair-ball. That's because I can study a hair ball and still have no idea what it is for and why they exist. String Theory and the elusive TOE is in the same category. I could go on my en

I left Christianity a few years ago and swore off religion altogether; however, after reading this book, string theory has become tantamount to religion in my life. Brian Greene writes beautifully about particles, planets, and the origins of our universe as we know it today. It is a heavy book- I don't recommend it for anyone who wants a quick, easy read. It took me almost two months to get through, but I learned a tremendous amount and came away in complete awe of the world and the forces at wo ...more

لنقل ان الفيزياء تنقسم الى نظريات .
فيزياء كلاسيكة ، فيزياء حديثة .
الفيزياء الكلاسيكة تفسر الكون على اساس معادلات نيوتن وهي صادقة لحد كبير في التنبوءات ومازالت تستعمل وتدرس في المدارس لحد الآن.
الحديثة تنقسم الى عدة اقسام : نظرية النسبية العامة والخاصة . نظرية الكم ، نظرية الاوتار الفائقة التي ادعت انها جمعت كل النظريات السابقة ..هناك ايضا سيناريوهات اخرى منها نظرية –ام و عدة اقتراحات اخرى تسمى بنظريات كل شيء ..

4.0 to 4.5 stars. There is a great quote to the effect that "if you can't explain a subject in non-technical terms so that a lay person can understand it than you haven't really mastered the subject yourself." On that basis, it is clear that Brian Greene has DEFINITELY mastered the subject of general relatively, quantum dynanmics and string theory (at least to the extent present technology allows). For such a complicated and often "non intuitive" subject, Greene does an excellent job of laying o ...more

AN INTRODUCTION BY WAY OF HYPERBOLIC SENTIMENT: The Elegant Universe is "The Bible" of superstring theory[*:].

I close the covers of The Elegant Universe with powerfully mixed feelings. On the one hand, Brian Greene gives us a lucidly-written layman's-terms explanation for high-concept modern physics, providing an excellent survey of 20th century science and painting a vivid picture of a promising strategy for reconciling the discrepancies in the otherwise dominant theories. On the other hand, ab

Greene's eminently readable attempt to explain the possibilities for string/superstrings to provide the linchpin for the long-awaited-and-desired merger of gravity with the two nuclear and electromagnetic forces into a Grand United Theory. Frankly, the entire idea of rolled up dimensions—of a universe containing perhaps ten, twelve, eighteen dimensions, of which we are only capable of perceiving four—is suitably mind-blowing and humbling at the same time; and although Greene's low-culture themed ...more

My local book club picked this book for our non-fiction month. I've been a part of this group- the largest-best Bay Area Book club!!!!

In the 5 years I been part of this group, I can't remember a more challenging book to fully understand. The superstring theory is 'taught' by Brian Green' for those of us with maybe a basic Physics level one course. I can't imagine understanding anything, without having had at least some High School or College physics. This book is not for everyone, yet it's Top N

This book blew my mind countless times as I read through it, so much so that I could usually only read 10-20 pages in one sitting. I had physics in high school, watched Cosmos and tons of other programs on the universe/relativity/quantum physics etc. so I have always had an interest but not enough to have that be my profession - nor am I smart enough in that way. Books like this let you visit that world for a while and this author does a fantastic job explaining general and advanced physics, Ein ...more

This book presents the latest breakdown of empirical existance with string theory- it's really well written and it sugguest how the fundimentals of all existing things come together in a very similar way as our understanding of music (little vibrations). I love this subject because, where the goal of civilization is to appreciate life in some form of organized chaos, some well spoken theorists have the ability to put things into perspective in such a way that the world seems to teem with possibi

I read this book while taking a course (for non-physics students) called Modern Physics in Perspective, which centered on string theory. I learned so, so, so much in this class & the book helped a lot. If you're reading this book unassisted, be aware that there are some very confusing sections that you'll need to read a few times. Sometimes his analogies are a bit too inane. Also, I've discovered that many physicists have an unhealthy obsession with their research pet projects- I'd advise th ...more

The first few chapters are fascinating as Greene recounts the history of modern physics, its departure from classical, Newtonian understanding. Then, he moves into string theory, and I found the arguments and explanations harder to follow. As Greene wrote the book just a few years after the Second Superstring Revolution, it makes sense that the arguments aren't as well-developed as those describing theories and experiments perfected and refined over the past 100 years or so. I really enjoyed the ...more

I never really got the hang of String Theory. I find it awfully weird and almost nigh-unscientific. Not being a physicist, I try not to make judgments about it, since I clearly don't understand it one bit - at least on the math level! - but I have to say that Brian Greene didn't endear it to me.

I also fervently found myself wishing for the Nth time that science books were not so firmly divided between "professional, terrifying math texts" and "written for people who never figured out the Theory

Dear God,

Will you ever allow us folks down here on Earth to come up with Einstein’s dream of a Theory of Everything (ToE)? The fact of the matter is that there are essentially two opposing theories upon which rests our knowledge of the universe: General Relativity and Quantum Mechanics. That is, the world of the large and the world of the miniscule. But whenever we try to unify them, our calculations just fall short; or better, fall large!, for we bump into infinity.

Oh wait!, this book has jus

This is the first book by Brian Greene that I read. The first chapters were amazing and engaging, however later chapters about string theory were very hard for me to understand and I actually didn't finish the whole book, because I could not understand what I was reading.

The author uses many metaphors to make his ideas simpler. He starts with a very easy to understand telling of history of scientific discoveries reaching to the theory of general relativity and quantum physics and the unification

Disclaimer: I am not a physicist. I have a MSc in environmental sciences which is 20 years out of date.

Brian Greene describes elegantly special and general relativity as well as important aspects of quantum physics in the first third of his book. It is worth its money for these first few chapters.

Unfortunately, his writing about the five string theories and their meta-theory called M-theory is almost unreadable and loses its focus very rapidly. Brian Greene seems to be so intimately and uncondit

I have copious notes where I disagreed with the author. While I understand he is probably the leading public proponent of string theory, I felt that his oversimplification lead to some really problematic axioms and it was upon these shaky foundations that he tried to map out string theory. I'm afraid I think that the Theory of Everything (or Grand Unified Theory) will be articulated in a much more coherent way if one sets aside the supposition that is string theory. This may also be an oversimpl ...more

Dr. Greene, unfortunately, imagines himself to be a much better writer and expositor than he actually is. Far too much time is wasted on silly examples to explain his points; so much that the analogies not only break down but become absurd. These concepts are not very difficult. Dr. Greene fairly well crosses the line into talking down instead of explaining things.

However, this book has some rather well laid out charts and diagrams and other visual aids. Importantly these come with a gracious de
