Whenever I try to read popular science books like this it feels like every sentence is an important idea, and when one enters my brain, two others get ejected and I end up dumber than when I started. Maybe there's a law of physics that will explain that. Too bad I won't remember it!

Finally finished! A great book for the non-science-y who want some understanding of string theory without the math. It was slow reading and I had to take notes to remember things, but still enjoyable reading. Greene explains everything so clearly, uses great analogies, and has a wonderful way with words to boot.

The Elegant Universe is a popular explanation of string theory. Yet, it is so much more than that. It is an illumination of the fascinating journey that physics has taken since Isaac Newton.

Starting with a brief overview of Newton's mechanics, dr. Greene then delves into fairly detailed non-mathematical descriptions of both Einstein's special and general relativity. Quantum mechanics is then briefly examined, especially the quantum weirdness phenomena and the uncertainty principle.

Then it's on about the super-symmetrical string theory, the physics' latest attempt to merge the generally hostile general relativity and quantum theories into a single theory describing all of nature's forces, including gravity.

Learn how this theory builds on the premise that the universe is built from tiny strings whose vibrations produce elementary particles such as photons, how there are likely more than three spatial dimensions, how transformations of these tiny dimensions create self-repairing rips in the fabric of space and how it all affects the cosmos around us.

Lucidly written in a clear, non-technical style, it is a pleasure to read as the author steers clear of both too convoluted popular culture references (like Cartman rolling down the hill in Hidden Universes) and from too inside-baseball like descriptions of the science and mathematics behind it.

One of the best popular science books that I've read. It is bound to blow your mind and bring you up to date on the state of modern physics, even though it's not of the newest date. Hopefully in the future dr. Greene will take the time to write a follow-up to bring us up to speed on the newest developments in string/M-theory. ( )

(Original review, 2001)

The Kabbalah also describes 10 dimensions and beings that inhabit them. Perhaps these beings are real and at certain levels of dimensional perception they have already seen and experienced these advancements in human history like a child being taught 2+2 to the wave compilation of an electron Y=h/mc = 2.43*10-12m.

Mathematics, My Daddy says is simply a game or a toy for the mind. I enjoy playing with math though I truly know now that it is not Universal Knowledge. Mathematics is like some sports. It brings Me fun and excitement. Sometimes I get low scores and I feel sad, but My Daddy simply tells Me that if I want to perfect the exams, I have to study harder. As you all can see, all the so called greatest mathematicians and scientists and physicists humans' scholars humans gave so much high regards to have immediately realized that all those books and all those studies and all those "humans once thought of as knowledge" became child's play if not garbage right upon My Daddy revealed this Universal Truth and Knowledge. 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.

The numbers below show and reveal the absolute humans' ignorance of The Universe: here on earth, humans' system of #counting #interpreting Time is by almost literally "counting" the tiks and the toks of our grandma's clocks:

a #millisecond timer counts from 0 to 1000 in 1 second.
a #nanosecond timer counts from 0 to 1000000 in 1 second.
a #picosecond timer counts from 0 to 1000000000 in 1 second

Humans' degrees of comprehension can only barely grasp what a picosecond is. This is the very reason why humans have so much avoided putting mass(m) on Time(t) because if that were so, and truly IT IS, mathematics would be useless as an old garbage program or application. So they humans began fooling themselves falsely thinking that they humans have been acquiring knowledge while truly what they have been acquiring and feeding their minds with are to the letter, garbage. THE UNIVERSE deals with Time as events, and with it, mass, energy, velocity, speed, and acceleration and everything. Each one, IS unique.

NVMEsecond is 1 second divided by 1 x 10 raised to the exponent 666.
NVMElightyear is 1 Lightyear multiplied by 1 x 10 raised to the exponent 666.

NVMEparticles are subsubatomic particles with lives half-lives ranging within trillionth of a trillionth of a trillionth...... of a trillionth of a NVMEsecond. They interconnect each and everything in The Universe. The Universal Internet. These particles are seemingly like "very tiny bubbles" connected to each and everything. Serving as Time Timers Transmission Mediums, these particles burst (in series) into tinier smaller particles. A Universal Timer Counter that can count 9999999999999999999 x 1 x 10 raised to the exponent 99999999999999999 within very small fraction of a NVMEsecond. Signals or information from 9999999999999999999999999 billion different star systems from 9999999999999999999999999 billion different super clusters 9999999999999999999999999 NVMElightyears apart are being transceived to and fro within small fractions of NVMEsecond.

How does someone describe, something - that we haven't developed a language for, so that we CAN describe it.
===
We start with 27 dimensions - of creation.
Outside creation we have some dimensions … that are born (not created).
These dimensions … contain .. what is needed - for the created dimensions (so that they can exist).
===
In the these dimensions ... every particle is … omnipresent (Read: infinity speed).
This .. is not: x=(a number) .. but .. f(x,l)=a result (that contains many different things). Among them - time (both movement and dimensions).
It also contains :
- The ability for life.
- The ability to create.
- The ability for "producing energy" (The emptiness between the rings).
(The energy is not produced, in the manner we use it, in "the daily
language", but as a result of two waves - "gathering mass", so that they can
become a wave.
"The Vacuum" between the waves - "becomes energy"
#####
[Read the beginning again: I said that we didn't have developed a language for this, yet.]
#####
- f(x,l) means here: function of (x=mass) and (l=liquid).
So … a "function of mass, liquid" - is OUR beginning .. LEADING to - the understanding
of the foundation … for creation.
...Then we can see:
-- Every star (included our sun), "plays" - "its own melody".
.....As long as the melody … is unchanged ... the star is "healthy".
.....When the melody changes - the star, starts "to die".
.....Through the understanding of string theory - this melody can be "repaired", so
........string theory may be a kind of "medical science" - in THIS context.
===
This is a simplified version, of a description - of what string theory might be.
The function … contains many more elements than mentioned here.
The main point, with this simplified explanation - is to show the possibility
for that we must look at string theory - in perception wider than
"x=(a number)".

NB: Amongst other things, I didn't appreciate how he glossed over the Kaluza-Klein theory; how it tied in with Einstein &; String-theory. Kaluza & Klein formulated GR in 5 dimensions & Electromagnetism, Maxwell’s equations simply fall out of the theory. This was the tie to String Theory which also encompasses both theories as Maxwell’s equations have already been unified with the rest minus GR in the standard model. ( )

Good but not gripping. Sometimes the analogies were not all that helpful and seemed to take a lot of time for little explanatory power, but on the whole still plenty to learn from listening to the book. ( )

Complessivamente un buon libro di divulgazione,che si occupa di teoria delle stringhe in maniera comprensibile,lasciando alle note alcune considerazioni più matematiche.Fa emergere anche la passione dei fisici teorici che si cimentano in questa branca della fisica.Manca di obiettività,essendo stato scritto da un fisico che si occupa di teoria delle stringhe e non presenta un punto di vista oggettivo sulla mancanza di evidenze sperimentali,ad esempio.Lettura consigliata.

First words
Preface
During the last thirty years of his life, Albert Einstein sought relentlessly for a so-called unified field theory—a theory capable of describing nature's forces within a single, all-encompassing, coherent framework.
Calling it a cover-up would be far too dramatic.

Book description
Physicists and mathematicians all over the world are feverishly working in these years on one of the most ambitious theories that have ever been conceived: the theory of superstrings, or strings, as it is often called. Einstein searched for more than thirty years without ever achieving a unified theory, which reconciled general relativity and quantum mechanics, the two cornerstones of twentieth-century physics. String theory provides perhaps the solution to this profound and fascinating problem, describing all the forces of nature in a single conceptual framework of supreme elegance.
Everything that is wonderful in the universe is the result of the vibrations of individual units, ultramicroscopic strings hidden in the depth of matter. The 'modes of vibration', the 'notes' intoned by these strings, determine the intimate constitution of matter, such as violin strings that perform an ordered and harmonious cosmic symphony.
In this book, Brian Greene tells the story of an extraordinary adventure, talking about it as a protagonist and transmitting all the enthusiasm of scientific discovery. The revolutionary vision of the universe that emerges from his story involves hidden and rolled up dimensions in the folds of space, black holes that are transformed into elementary particles, discontinuity in the weaving of spacetime and universes that generate other universes.
"The elegant universe" describes with intelligence and vivacity the exhilarating discoveries and the still unsolved mysteries of the universe. Through the wise use of analogies and fascinating metaphors, Greene manages to make immediately accessible some of the most complex and sophisticated concepts of contemporary physics.

Haiku summary

Amazon.com Amazon.com Review (ISBN 0375708111, Paperback)

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
