Verified Purchase. I bought this book and also The Grand Design by Stephen Hawking and this one was definitely more like the type of book I was looking for. The Grand Design was basically a physics book that just covered theory after theory but this one really connected the dots and made me realize a lot about our universe. Do yourself a favor and skip The Grand Design and just purchase this one.

Hawking never disappoints as he takes the most complicated subjects and makes it easy to understand and fun to delve into. A mind like his comes along once in a generation and we were fortunate to have him, as did all the students he touched during his tenure at Cambridge University. I have several other "illustrated" versions of Hawking's books and those have become my favorite versions because I love the large format and the illustrations inside are generally really well done and actually help with the text, especially for those people who have a hard time mentally visualizing the theories explained within.

For some reason I picked this book to be my first Kindle book by Hawking. Perhaps I thought I just couldn't "wait" for the physical book to arrive. Big mistake. No color illustrations. No greyscale illustrations. No black-and-white illustrations. No line-art. None whatsoever. None on the Kindle 3G. None on the Kindle Reader for Mac. None on the Kindle reader for iPad.

In summation, do NOT buy this book on Kindle. If you want to buy it for Kindle, I wouldn't even recommend the non-illustrated version. The text only portion of this book is exceedingly short and offers essentially nothing new from those other books. This does include illustrations, which add substantially to the book.

The illustrations are good quality and appropriate. Reading the book on Kindle Reader for iPad works pretty well, with full-color photos which are in-line two-finger gesture to expand the pictures. On my Kindle 3 Kindle with Keyboard , some of the images have very low contrast.

Many of the images also have a light grey text which is somewhat difficult to read, even when expanded. Other than the presence of illustrations in the updated kindle version, the best update is the presence of highlight boxes kind of like side-bars but in-line which break up the text and enhance the experience.

I am updating my rating to 3 stars. I have other Kindle books which are not advertised as "illustrated" which have similar numbers of illustrations chapter heading pictures, or just other pictures that enhance the content.

Stephen Hawking was a good teacher: And he also had a contagious enthusiasm about tackling complex problems. Now that he is no longer with us, he remains with us through his writings. This book makes his present and endearing. One person found this helpful. Hardcover Verified Purchase. This book is a new edition of a book originally published in based in seven Cambridge lectures, basically describing some of the contributions of the author to cosmology and black holes.

Among those: Some of the concepts are very clearly explained such as the second law of thermodynamics, the black hole horizon, black hole evaporation, virtual particles, etc, although some others are more difficult to grasp.

An artist's sketch of a black hole's event horizon Sometimes when we look at the evening sky, observe a shooting star far away or admire the beauty of moon, we are overpowered by this idea of our seemingly insignificant existence in the Universe.

For if we compare our very own presence, that of our world or our country, even of our planet or our galaxy with the Universe, it is bewildering that we seem to occupy not even a speck of dust as compared to the vastness of the Universe.

Many of us are t An artist's sketch of a black hole's event horizon Sometimes when we look at the evening sky, observe a shooting star far away or admire the beauty of moon, we are overpowered by this idea of our seemingly insignificant existence in the Universe.

Many of us are then tempted to delve into the mysteries of this existence to make out some meaning, some significance. Whereas philosophy seems to correspond to our inner being in relation to world around, we need to turn to science in order to understand our relation with the Universe. The attempt thus taken, even though neither Science nor Philosophy seems to offer an absolute explanation, may bring about a more modest outlook towards our existence and empathy towards fellow beings.

But since most of the scientific theories and their explanation are available theoretically in a technical manner, not many of us make an attempt to understand them.

In this work, Hawking not only suggests making scientific knowledge simpler enough for everyone so that more people can understand and benefit from it but also presents to us scientific theories in very simple way. Moreover he is also quite witty at certain places, which makes the work an enjoyable read e.

Strictly, this is what is known as the weak cosmic censorship hypothesis: But it does nothing at all for the poor unfortunate astronaut who falls into the hole. Thus even though we have not yet managed to find a primordial black hole, there is fairly general agreement that if we did, it would have to be emitting a lot of gamma and X rays. If we do find one, I will get the Nobel Prize. Towards the end, when Hawking discusses the need of a unified theory and the question why such a theory may not be possible, he ends his lecture in the following manner: However, if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists.

Then we shall all be able to take part in the discussion of why the universe exists. If we find the answer to that, it would be the ultimate triumph of human reason. For then we would know the mind of God. I will recommend this book to all those who want a have an idea about the Universe in terms of theories developed so far.

## The Theory of Everything : Stephen Hawking :

This book is a boon for physics lover. The author didn't include complicated mathematical equations. He kept language simple and easily understandable.

The author mixes science with philosophy. It exhibits a subtle sense of humor in the book. It's a short read. Stephen Hawking poses interesting questions about God. All in all, a recommended reading. Read full review - Books Charming. View 2 comments. I wasn't sure what to expect when I approached this book. Being such a huge Einstein fan and knowing how he struggled in his own, final quest for the Theory of Everything just before he died, well, I didn't know what to think.

Had Hawking finally cracked that elusive nut? I was originally homeless when I first discovered this book, and living in my car with my 2 cats. I would head to the library on special days to kill time, and immediately go to this book and throw myself into its pages. I'd alw I wasn't sure what to expect when I approached this book. I was pleasantly surprised at the amount of levity and wit Hawking used to approach his topical essays! And he made a successful, conscious choice to remove most of the superfluous "professor-speak" and attempt to keep it on a level that most non-scientists could understand.

I commend him for that. This book was a bit of an eye-opener for me. My favourite essays were of those on black holes. The interesting thing, is that since reading this book, we have discovered the existence of hyper-giants, which weren't around when Chandresekhar devised his now famous, "Chandresekhar limit" when calculating at what conditions an imploding star would finally fold under the mass of itself and become a black hole. It makes me wonder what this now does to his limit calculations.

All in all, a superb book for the scientist and non-scientist alike. Highly recommend. Dec 05, Ahmed Abdelhamid rated it liked it. View all 6 comments. Feb 25, Swati rated it really liked it.

It is followed by explaining that why universe is non-static, future of stars, different evolutionary models, flaws in them, the paradox which is created if we assume singularity to be existent at the time of bing bang, concepts of quantum gravity and imaginary time to find solutions for fundamental limitations arising because of singularity assumption, possible histories of universe and ultimately capability of string theory to resolve unsolved mysteries.

At the end author has explained that why unified theory is not possible presently but might be possible in future. Author does tried to add light humour in some parts. Fascinating read! May 27, Kaustubh rated it it was amazing. Not a novel per se but a collection of lectures by Mr Hawking, which explores the origins of the universe and tries to find the answer to "Why does the Universe exist, anyway?

He thus tried to describe "everything" starting from a few axioms. Any "theory of everything" is similarly expected to be based on axioms and to deduce all observable phenomena from them. Following Democritean atomism , the mechanical philosophy of the 17th century posited that all forces could be ultimately reduced to contact forces between the atoms, then imagined as tiny solid particles. In the late 17th century, Isaac Newton 's description of the long-distance force of gravity implied that not all forces in nature result from things coming into contact.

Newton's work in his Mathematical Principles of Natural Philosophy dealt with this in a further example of unification, in this case unifying Galileo 's work on terrestrial gravity, Kepler 's laws of planetary motion and the phenomenon of tides by explaining these apparent actions at a distance under one single law: In , building on these results, Laplace famously suggested that a sufficiently powerful intellect could, if it knew the position and velocity of every particle at a given time, along with the laws of nature, calculate the position of any particle at any other time: An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to analysis, it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes.

Laplace thus envisaged a combination of gravitation and mechanics as a theory of everything. Modern quantum mechanics implies that uncertainty is inescapable , and thus that Laplace's vision has to be amended: During the 19th and early 20th centuries, it gradually became apparent that many common examples of forces — contact forces, elasticity , viscosity , friction , and pressure — result from electrical interactions between the smallest particles of matter.

In his experiments of —50, Michael Faraday was the first to search for a unification of gravity with electricity and magnetism. In , David Hilbert published a famous list of mathematical problems. In Hilbert's sixth problem , he challenged researchers to find an axiomatic basis to all of physics. In this problem he thus asked for what today would be called a theory of everything.

In the late s, the new quantum mechanics showed that the chemical bonds between atoms were examples of quantum electrical forces, justifying Dirac 's boast that "the underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known".

## The Theory of Everything : The Origin and Fate of the Universe

After , when Albert Einstein published the theory of gravity general relativity , the search for a unified field theory combining gravity with electromagnetism began with a renewed interest. In Einstein's day, the strong and the weak forces had not yet been discovered, yet, he found the potential existence of two other distinct forces -gravity and electromagnetism- far more alluring.

This launched his thirty-year voyage in search of the so-called "unified field theory" that he hoped would show that these two forces are really manifestations of one grand underlying principle.

During these last few decades of his life, this quixotic quest isolated Einstein from the mainstream of physics. Understandably, the mainstream was instead far more excited about the newly emerging framework of quantum mechanics. Einstein wrote to a friend in the early s, "I have become a lonely old chap who is mainly known because he doesn't wear socks and who is exhibited as a curiosity on special occasions. Einstein intensely searched for, but ultimately failed to find, a unifying theory.

## The Theory of Everything: The Origin and Fate of the Universe

Einstein—Maxwell—Dirac equations. More than a half a century later, Einstein's dream of discovering a unified theory has become the Holy Grail of modern physics. In the twentieth century, the search for a unifying theory was interrupted by the discovery of the strong and weak nuclear forces or interactions , which differ both from gravity and from electromagnetism. A further hurdle was the acceptance that in a TOE, quantum mechanics had to be incorporated from the start, rather than emerging as a consequence of a deterministic unified theory, as Einstein had hoped.

Gravity and electromagnetism could always peacefully coexist as entries in a list of classical forces, but for many years it seemed that gravity could not even be incorporated into the quantum framework, let alone unified with the other fundamental forces.

For this reason, work on unification, for much of the twentieth century, focused on understanding the three "quantum" forces: The first two were combined in —68 by Sheldon Glashow , Steven Weinberg , and Abdus Salam into the "electroweak" force. At higher energies Ws and Zs can be created easily and the unified nature of the force becomes apparent.

While the strong and electroweak forces peacefully coexist in the Standard Model of particle physics, they remain distinct. So far, the quest for a theory of everything is thus unsuccessful on two points: A Theory of Everything would unify all the fundamental interactions of nature: Because the weak interaction can transform elementary particles from one kind into another, the TOE should also yield a deep understanding of the various different kinds of possible particles.

The usual assumed path of theories is given in the following graph, where each unification step leads one level up:. In this graph, electroweak unification occurs at around GeV, grand unification is predicted to occur at 10 16 GeV, and unification of the GUT force with gravity is expected at the Planck energy , roughly 10 19 GeV.

Grand unification would imply the existence of an electronuclear force; it is expected to set in at energies of the order of 10 16 GeV, far greater than could be reached by any possible Earth-based particle accelerator. Although the simplest GUTs have been experimentally ruled out, the general idea, especially when linked with supersymmetry , remains a favorite candidate in the theoretical physics community.

Supersymmetric GUTs seem plausible not only for their theoretical "beauty", but because they naturally produce large quantities of dark matter, and because the inflationary force may be related to GUT physics although it does not seem to form an inevitable part of the theory. Yet GUTs are clearly not the final answer; both the current standard model and all proposed GUTs are quantum field theories which require the problematic technique of renormalization to yield sensible answers.

This is usually regarded as a sign that these are only effective field theories , omitting crucial phenomena relevant only at very high energies. The final step in the graph requires resolving the separation between quantum mechanics and gravitation, often equated with general relativity.

In addition to explaining the forces listed in the graph, a TOE may also explain the status of at least two candidate forces suggested by modern cosmology: Furthermore, cosmological experiments also suggest the existence of dark matter , supposedly composed of fundamental particles outside the scheme of the standard model.

However, the existence of these forces and particles has not been proven. Since the s, some physicists such as Edward Witten believe that dimensional M-theory , which is described in some limits by one of the five perturbative superstring theories , and in another by the maximally- supersymmetric dimensional supergravity , is the theory of everything. However, there is no widespread consensus on this issue.

In this regard, string theory can be seen as building on the insights of the Kaluza—Klein theory , in which it was realized that applying general relativity to a five-dimensional universe with one of them small and curled up [ clarification needed ] looks from the four-dimensional perspective like the usual general relativity together with Maxwell's electrodynamics. This lent credence to the idea of unifying gauge and gravity interactions, and to extra dimensions, but did not address the detailed experimental requirements.

Another important property of string theory is its supersymmetry , which together with extra dimensions are the two main proposals for resolving the hierarchy problem of the standard model , which is roughly the question of why gravity is so much weaker than any other force. The extra-dimensional solution involves allowing gravity to propagate into the other dimensions while keeping other forces confined to a four-dimensional spacetime, an idea that has been realized with explicit stringy mechanisms.

Research into string theory has been encouraged by a variety of theoretical and experimental factors. On the experimental side, the particle content of the standard model supplemented with neutrino masses fits into a spinor representation of SO 10 , a subgroup of E8 that routinely emerges in string theory, such as in heterotic string theory [20] or sometimes equivalently in F-theory. In the late s, it was noted that one major hurdle in this endeavor is that the number of possible four-dimensional universes is incredibly large.

This array of models is known as the string theory landscape. One proposed solution is that many or all of these possibilities are realised in one or another of a huge number of universes, but that only a small number of them are habitable. Hence what we normally conceive as the fundamental constants of the universe are ultimately the result of the anthropic principle rather than dictated by theory. This has led to criticism of string theory, [29] arguing that it cannot make useful i. Others disagree, [30] and string theory remains an active topic of investigation in theoretical physics.

Current research on loop quantum gravity may eventually play a fundamental role in a TOE, but that is not its primary aim. There have been recent claims that loop quantum gravity may be able to reproduce features resembling the Standard Model. So far only the first generation of fermions leptons and quarks with correct parity properties have been modelled by Sundance Bilson-Thompson using preons constituted of braids of spacetime as the building blocks.

Utilization of quantum computing concepts made it possible to demonstrate that the particles are able to survive quantum fluctuations.

This model leads to an interpretation of electric and colour charge as topological quantities electric as number and chirality of twists carried on the individual ribbons and colour as variants of such twisting for fixed electric charge.

Bilson-Thompson's original paper suggested that the higher-generation fermions could be represented by more complicated braidings, although explicit constructions of these structures were not given. The electric charge, colour, and parity properties of such fermions would arise in the same way as for the first generation.

The model was expressly generalized for an infinite number of generations and for the weak force bosons but not for photons or gluons in a paper by Bilson-Thompson, Hackett, Kauffman and Smolin. Among other attempts to develop a theory of everything is the theory of causal fermion systems , [36] giving the two current physical theories general relativity and quantum field theory as limiting cases.

Another theory is called Causal Sets. As some of the approaches mentioned above, its direct goal isn't necessarily to achieve a TOE but primarily a working theory of quantum gravity, which might eventually include the standard model and become a candidate for a TOE. Its founding principle is that spacetime is fundamentally discrete and that the spacetime events are related by a partial order. This partial order has the physical meaning of the causality relations between relative past and future distinguishing spacetime events.

Outside the previously mentioned attempts there is Garrett Lisi's E8 proposal. This theory provides an attempt of identifying general relativity and the standard model within the Lie group E8.

The theory doesn't provide a novel quantization procedure and the author suggests its quantization might follow the Loop Quantum Gravity approach above mentioned.

Causal dynamical triangulation does not assume any pre-existing arena dimensional space , but rather attempts to show how the spacetime fabric itself evolves. At present, there is no candidate theory of everything that includes the standard model of particle physics and general relativity. For example, no candidate theory is able to calculate the fine structure constant or the mass of the electron. Most particle physicists expect that the outcome of the ongoing experiments — the search for new particles at the large particle accelerators and for dark matter — are needed in order to provide further input for a TOE.

In parallel to the intense search for a TOE, various scholars have seriously debated the possibility of its discovery. Stanley Jaki , in his book The Relevance of Physics , pointed out that, because any "theory of everything" will certainly be a consistent non-trivial mathematical theory, it must be incomplete.
