The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory
With a new preface (not in any other edition) that will review the enormous public reception of the relatively obscure string theory—made possible by this book and an increased number of adherents amongst physicists—The Elegant Universe "sets a standard that will be hard to beat" (...more

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 ...more
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 ...more
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 ..

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 ...more
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 ...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 ...more
E' un Universo difficile, lavoro duro e destino incerto.
Dopo Zygmut Baumann, ci voleva anche la fisica quantistica a toglierci ogni certezza, immersi in un cosmo che funziona come un mantice, si gonfia e si sgonfia (forse), e noi in mezzo, a vivere chissà, forse più vite, su più dimensioni, arrotolate come bigodini o srotolate come tappeti.
Richard Feynman, guru della meccanica quantistica, disse “penso di poter affermare con sicurezza che nessuno capisce la meccanica quanti ...more
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 ...more
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 ...more
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 ...more
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 ...more
My opinion of this book is similar but not equal to Rob's (though I liked his review), because I didn't think the first third of the book gave me a fairly good understanding of the Einstein's relativity concepts at all. For instance, the rubber membrane - bowling ball analogy was ...more
However, this book has some rather well laid out charts and diagrams and other visual aids. Importantly these come with a gracious de ...more
