The Road to Reality: A Complete Guide to the Laws of the Universe
The Road to Reality is the most important and ambitious work of science for a generation. It provides nothing less than a comprehensive account of the physical universe and the essentials of its underlying mathematical theory. It assumes no particular specialist knowledge on the part of the reader, so that, for example, the early chapters give us the vital mathematical bac...more

Many of my all-time favourite books make the list because they show you what it's like to be inside the mind of an extraordinary person. While you're reading them, Churchill's History of the Second World War and Yourcenar's Mémoires d'Hadrien let you be a great statesman at a pivotal moment in history. Simone de Beauvoir's autobiography, more than any other book I know, gives you the feeling of being a major literary figure. Polugayevsky's Grandmaster Preparation, which many chessplayers treat a...more
Dave Langford, SF&F critic and reviewer, in his long-since defunct column for White Dwarf magazine, once said that, "There is a tendency to over-praise big books simply because one has got through them." I agree that this tendency exists but note that Langford gave no reason for it. I think the reason is more or less macho intellectual pride; look at me! I read this honking great saga! It must be great or I'd have to admit wasting my time! And I need to show off my intellectual credentials!...more
Penrose came to GT and gave an open lecture on cosmic parameters and cosmological arguments from the 2nd Law of Thermodynamics (chapter 27 in this book, one of the most ambitious and impressive -- if incomplete, a bit uneven, and just as taxing as you've heard -- catechisms I've ever read), and a closed lecture on twistor theory (chapter 33), and signed my copy! w00t! I shook Sir Roger's hand as trillions of neutrinos passed through us both, completely undetected, our entangled R-type state evol...more
The Tao that can be named
is not the eternal Tao
What we know of physics is "the Tao that can be named"; and while it is an incomplete and imperfect representation of the eternal Tao, it is still fascinating and incredibly beautiful.
Don't ask me why reading books on mathematics and the physical sciences always puts me in mind of the Tao te Ching. I think because studying these things is the closest I really ever come to religious wonder, the awe of the infinite, and the woeful incapacity of our pu...more

this book RULES. it is a sort of primer on the mathematics required to really understand quantum physics. of course, that is a pretty huge pile of stuff, and this is a damn huge book. it moves faaast too: the entire theoretical foundations of single-variable calculus takes up one chapter. the reader is rapidly pulled through pretty heavy cram sessions in multivariable calculus, algebraic topology, real analysis... everything you need! and yet, it does not feel at all dense, because roger penrose...more
This book is too sprawling to wait and review all at once at the end, so I've decided to do it little by little as I go along.
I thought the prologue sucked, but immediately after that it became deeply fascinating, so don't get discouraged. I guess I should say why I hated it, though. It seemed as though he was judging former times and societies through a "presentist" lens, as though all people have always and only been scientists since the start of time, only they were really bad at it back then...more

I desperately want to make it through this book. I might be crazy. I think part of my fascination with finishing it is to compensate for not finishing engineering school. I can tell you this... It would be a lot easier to read if I had attained my degree (and actually learned the material along the way). Nonetheless, this book opens in the most interesting and captivating fashion, which says a lot about a book that works to explain the universe by walking through the history of mathematics.

As accurate a title as can be for this tremendously ambitious behemoth. I very much enjoyed the masterful laying of a mathematical framework when first I came across it (the first dozen or so chapters if memory serves; hence the rating, as well as for the aforementioned ambition in the task- I think this is a right way to go, though popular expositors seldom venture down this route), as Penrose does it so efficiently (and naturally too, so that the layman wouldn't shove it aside in disgust after...more
This excellent, definitive work is not for the faint of heart of the weak of mathematics. You'll have finished most of the material for an undergraduate degree in math by the time you've worked your way through this: the first half of the book starts with Pythagorean number theory, complex number calculus, Riemann surfaces, Fourier decomposition, n-dimensional manifolds, Lie symmetry groups, and builds out from there. However, rich fruit is reaped in the second half of the book, which delves dee...more

physics: link to math, relativity, quantum mechanics
This is a great book. I have finished reading the first part i.e, math part of the book. It opened lot of windows for me in the world of mathematics. Though a computer graduate, I have lot of interest in physics. I have read lot of material on relativity but none gave me the the insight to it like this book. Before this book, I had no knowledge of non-eucildean geometry and its importance to physics. But now I know lot about Riemann and other great people's contribution.

Penrose examines the turn modern theoretical physics has taken in pursuit of multi-dimensional mathematical models to develop a unified model of the sub-atomic realm. His argument is not entirely mathematical, though he does have good arguments against unnecessary complexity from the point of view of the straightforward progress made by theoretical physics in discovering the mathematical elegance of relationships among various observed constants. His most profound argument against String Theory...more
This is an audacious book, and a daunting read. Despite the months I spent working my way through it, I feel I barely scratched the surface, and I'm ill-equipped to really review it. A few random thoughts follow.
The book takes the refreshing (and unpopular amongst most pop-science books) view that the physics can't really be discussed without developing the necessary mathematical foundations, and it spends quite a lot of time introducing those mathematical subjects. That being said, it is probab...more

So we had a physicist around to dinner the other day and thrust this at him. I can't call T---- by his real name, let's just say he rhymes with a dip made with chickpeas and tahini. The reason I can't call him by his real name is that he works at a place that starts with C and rhymes with a complete lack of humour. He likes his job, I don't want to get him sacked for reading Penrose.

Amazing. While I can not exactly call Road to Reality a popularization of general relativity and quantum theory, it is a peerless introduction to and review of those topics. I have a PhD in mathematics, and studied physics and math as an undergraduate, and there was plenty for me to learn from this book. There are very few people in the world who would not learn much from reading it.

How Would a Physicist Think About the Quantum World?
I usually fly through books, and have no problem understanding them. Not this one. Over a year after I first cracked it, I am finally done. I am amazed by the rigor of this work. In fact, I can say that I “sort of” understand the major concepts of quantum mechanics as a physicist would.
Most popularizations of quantum physics are simplifications, ignoring the math. More insidious, the concepts of quantum mechanics are used to “justify” some scie...more

I have a suspicion that Penrose hasn't spoken to a undergraduate in 30 years. His notion of "introductory material" is not just wrong, its downright strange.
The famed mathematician devotes several pages to discussing the addition of fractions then breezes through holomorphic functions and Reimann spheres.
I'll return to this book in a year or two when I have the mathematical background to qualify as a "non-mathematician."

When the world was younger and more innocent - well, maybe not so innocent - cultured men and women were expected to be conversant with all of the latest ideas, not only in fashion, politics and literature, but also in the realms of philosophy and the sciences. I am referring to the era when Emilie du Chatelet provided the first translation of Newton's Principia into French, when she and her erstwhile husband Voltaire collaborated on physics and chemistry experiments, and when it would have been...more
There are three great things about this book (apart from the subject itself, which is the reason that I read it in the first place); the scope, the structure, and the level of detail.
The scope is simply all modern fundamental physics, which is impressive in itself. The structure is different from most other popular science books in that the first third of the book is almost entirely pure mathematics, covering most of the theory that is needed to understand the actual physics; basic definitions o...more

This book is well known to be readable for a wide range of audiences. Penrose does a superb job of marrying theoretical physics with geometry. Laymen can skip the equations and be treated to intuitive explanations of cutting edge physics. Experts will gain a more holistic understanding of the ties between math and physics. Penrose is not shy in this book about graduate level mathematical terminology and notation, and he accompanies it with beautiful geometric imagery and intuition. Due to the wi...more
This is a truly amazing work. Unfortunately, you need to be as clever as Roger Penrose himself to understand all of it. I am obviously not in that category!
The text-book of all text-books, although it really isn't one. Roger Penrose sets out to transmit his lifetime's accumulation of knowledge.
Despite having a background in Maths and Astrophysics, I was left wishing I knew a lot more in order to truly appreciate all he has to say.

Penrose, Penrose, Penrose. Oh how I LONG to know thee. I am becoming minorly obsessed with you and your work. I am pacing for crying out loud. I am running myself in circles. Opening, closing, referencing, coming back, straining my eyes as if that will make me see the world that you do. Why do you elude me so? Why does your tongue speak as if attached to the left temporal lobe itself? I catch glimpses of this reality you see. I feel myself drawn to it in longing for truth and understanding. For...more

Great read provided that you have the sufficient scientific background. Albeit in the preface, the author promises to keep the stuffs accessible to non-mathematical readers (to the level of them who can't see the equality between 3/4 and 6/8), from the third chapter onwards, the contents became a bit too technical, so much so that anyone even with an undergraduate mathematics background will find most of the concepts difficult to fathom. But still, if you are passionate about physics/mathematics...more
By his own admission in the preface, this is Penrose' attempt to popularize the current thinking in theoretical physics, including quantum mechanics, relativity, and unification theories such as string theories and quantum gravity. In the introduction he says (paraphrased) that he has intentionally gone for the more mathematical route, in spite of advice to the contrary, but he hopes that those without a mathematical bent can just skip the equations and get the gist of the concepts anyway.

Wow, this book covers so much material I don't even know where to start. Nor am I exactly qualified to review a few of the more advanced topics, but I haven't finished the thing yet, so I'm working on it. This is not a textbook per se, and it reads much more smoothly and purposefully than a boring theorem, proof type structure. Just an fyi though, the first third or so is essentially a survey/seminar on modern math. It begins benignly with philosophy, euclidean geometry, and intro to hyperbolic...more
I have read this book once. It will take at least two more reading before I can absorb everything I want from it. If you are into this kind of stuff, particularly with all the "Through the wormhole" etc., etc., a read like this is good information. As to where you can use that information, well, where can you use the info about Winston Churchill except in conversation. Just the self satisfaction of having acquired the knowledge in a world changing faster than we can possibly keep up.

Most of the topics introduced in this book I only understood after having studied them with proper textbooks. Now that I learned some of this stuff, that book is readable, but back then... Penrose is a horrible science popularizer. The content itself is good once you can read it and know what he's talking about, but it's too hard for someone with a mere high school math background, and I guess way too hard for someone who can't even understand fractions unlike what Penrose claims.

This is a very comprehensive work by Penrose. It is also a very difficult book for me to read. I definitely rate it five stars for the reason that there are no other books of its kind or in its class that I know of. This is a must read for all who are interested in TOE.

“We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.”
