Why do the forces have such different properties? The electromagnetic force is the next most familiar of the four. Instead they showed that each consists of three smaller particles, called quarks--a whimsical name taken from a passage in James Joyce's Finnegan's Wake by the theoretical physicist Murray Gell-Mann, who previously had surmised their existence. Once the part on string theory started at about 25% of the book things rapidly become more complicated with descriptions of multidimensional geometries and behaviours of these dimensions. The main arguments I have retained are as follows: string theories are beautifully elegant. إذاً حولت النظرية العالم لسيمفونية من العزف الجماعى لترليونات الترليونات من الأوتار في كل سنتيمتر من الكون و لم تكتف بذلك بل أضافت إلى الأبعاد المعروفة سبعة أبعاد جديدة ليصبح لدينا إحدى عشر بعدا منها بعد زمنى واحد و عشرة أبعاد للمكان.

The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory by Brian Greene

the elegant universe

Far from being the most elementary material constituent, atoms consist of a nucleus, containing protons and neutrons, that is surrounded by a swarm of orbiting electrons. The author gives good examples and analogies to better understand the complex thematic. Welcome to the 11th dimension. The strength of the gravitational force also plays a formative role. Literally speaking, humans are among the most primitive civilizations in The Universe and yet we humans are very arrogant, sinful and blasphemous because we, humans do not know any better. In fact, we shall see that the conflict between general relativity and quantum mechanics is actually not the first, but the third in a sequence of pivotal conflicts encountered during the past century, each of whose resolution has resulted in a stunning revision of our understanding of the universe. You go get them my fairy little oscillating strings, which so happen to explain black holes! Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity.

the elegant universe

The international bestseller that inspired a major Nova special and sparked a new understanding of the universe, now with a new preface and epilogue. The Elegant Universe is a rewarding read…Einstein would approve. Smolin's , 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. Unfortunately, his writing about the five string theories and their meta-theory called M-theory is almost unreadable and loses its focus very rapidly. After he builds the foundation, he sets the stage to cover string theory which many believe will be the next great leap in figuring out why the universe exists and where is it going. Or, maybe those older concepts are just better understood by the physicists themselves, I couldn't tell.

The Elegant Universe (Audiobook) by Brian Greene

the elegant universe

Based on The elegant universe by Brian Greene. It was a prescient guess. Many physicists were also expecting to find supersymmetric particles, but none have been detected. These faults aside, The Elegant Universe is the only book about science that I have ever read from start to finish and enjoyed from start to finish. Wilson, Robert Trivers, and others is a strong one that explains a whole lot but you better be careful before you go painting too broad of a stroke with those kinds of theories.

There's this old Nasrudin story, where he's somehow ended up as judge in a court case. I wondered what would happen if they didn't find any supersymmetric particles? One of these is the gravitational force. This is why these two forces were discovered only much more recently. And if the most clever mathematicians and physicists believe this, the not so gifted have no choice than to support their view. Smolin's , 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.

the elegant universe

A vertible Bible of where we came from, where we're going and the incredibly complex way things function in this glorious universe of ours. 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. . There are ample evidences that proves this theory to be correct. The Physics of God describes the intersections of science and religion. It is an extension of string theory that suggests the elementary particles of the universe might include, in addition to strings, two-dimensional membranes and three-dimensional blobs of varying size. Rather, space and time emerged from Einstein's reworking as malleable constructs whose form and appearance depend on one's state of motion.

Greene ends his discussion of the latest advances in superstring theory by discussing its cosmological implications, what it might reveal about the origins of the universe. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth. I can't imagine understanding anything, without having had at least some High School or College physics. Disclaimer: I am not a physicist. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist. 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 عندما سقطت التفاحة التوراتية سقطنا معها إلى هذا العالم و من ثم أصبح لزاما علينا أن نفهمه أو على الأقل نفهم كيف نعيش فيه. In all but the most extreme situations, physicists study things that are either small and light like atoms and their constituents or things that are huge and heavy like stars and galaxies , but not both.

In the nineteenth century scientists showed that many familiar substances such as oxygen and carbon had a smallest recognizable constituent; following in the tradition laid down by the Greeks, they called them atoms. لذا لا غرابة في ان سمى كتابه الكون الانيق. After praising the elegance and economy of the theory, Greene gives a brief history of its first incarnation in the 1970s, when it was referred to as the bosonic string theory. Like many of his colleagues, Greene simply cannot accept that the universe is, at its core, divided into two contradictory theoretical frameworks. Sin da piccola, mi ponevo le più disparate domande sul mondo che ci circonda, sulle stelle, sui pianeti e sullo spazio infinito e mi divertivo ad immaginare le teorie più strampalate riguardo le leggi che governano l'universo. Searching for the smallest bundle of the feeblest force is quite a challenge. The Three Conflicts The first conflict, recognized as far back as the late 1800s, concerns puzzling properties of the motion of light.

Overall conclusion: it is a boring documentary, it provides you with a lot of opinions. Sometimes his analogies are a bit too inane. Briefly put, according to Isaac Newton's laws of motion, if you run fast enough you can catch up with a departing beam of light, whereas according to James Clerk Maxwell's laws of electromagnetism, you can't. It reminds me of when Robert Wright hedges his bets in , saying that the evolutionary psychology approach as championed by himself, Richard Dawkins, E. As string theory is as yet purely theoretical, it is very very difficult to follow for non-experts like myself and close to impossible to comprehend the practical implications. Not only are space and time influenced by one's state of motion, but they can warp and curve in response to the presence of matter or energy.
