# The Road to Reality: A Complete Guide to the Laws of the Universe

Roger Penrose, one of the most accomplished scientists of our time, presents the only comprehensive and comprehensible account of the physics of the universe. From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics,

Well you are never finished with such a book, titled “The road to reality” but actually providing more than that: providing nothing less than a “road-map” to reality, and opening to the reader new beautiful vistas in modern mathematics and physics. I am sure that I will come back to this book in the future, as a source of inspiration and for future reference.

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

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."

But can I really say that I'm done with this book? I don't think so... Although it took me a year and a half to read it, I didn't even understand a significant part of it. Since I'm a physics student I understood most of it on some very basic level, but I'm pretty sure I'll have to open this book again and again to take a peek at some of the awesome ideas put here by Penrose.

Did I say awesome? That's a huge understatement ...more

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.

This is an exhaustive review of the laws of physics as related to physical reality with significant emphasis on the mathematical component. The author is an outstanding mathematical physicist of our times, and in this book of 1100 pages, he describes the concept of space, time, and matter (energy) in terms of classical physics, quantum physics, string theory and its derivatives.

In physics, the behavior of objects is understood in terms ...more

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

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. A co

marked it as half-read

This book is not for those with no strong background in mathematics and physics and it is definitely not for lay readers.

Except for the first 40 pages or so the book material was very sophisticated and hard to understand for me. Today I decided to stop as for the past 30 or so oages I could only understand little of what I was reading.

I'm putting it on hold now and I may return to it later after establishing a strong base in mathematics and physics.

Penrose is a master of his field. This text has exercises in it that range from simple expositions to those that will take weeks of serious thought. If you are a student of physics, this text casts the widest net possible, touring you through all of the mathematics and physics that you will become intimately familiar with in connections and expositions that you will rarely find in single courses.

Penrose is a pre-eminent mathematician whose work has affected my own thinking in deep ways. Often I've discovered, to my surprise, that some viewpoint which I learned from another source in fact derived ultimately from Penrose himself, the author of this other source having been, as it turns out, a student of Penrose. As an example I offer "Visual Complex Analysis" by Tristan Needham. ...more

“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.”

“No doubt there are some who, when confronted with a line of mathematical symbols, however simply presented, can only see the face of a stern parent or teacher who tried to force into them a non-comprehending parrot-like apparent competence--a duty and a duty alone--and no hint of magic or beauty of the subject might be allowed to come through.”
