This book is my quest to explore the ultimate nature of reality, from the microcosm to our universe and beyond. If you join me by reading it and discussing with me on Facebook, then it will be our quest!

"Our Mathematical Universe boldly confronts one of the deepest questions at the fertile interface of physics and philosophy: why is mathematics so spectacularly successful at describing the cosmos? Through lively writing and wonderfully accessible explanations, Max Tegmark—one of the world's leading theoretical physicists—guides the reader to a possible answer, and reveals how, if it's right, our understanding of reality itself would be radically altered." —Prof. Brian Greene, physicist, author of The Elegant Universe and The Hidden Reality

"Daring, Radical. Innovative. A game changer. If Dr. Tegmark is correct, this represents a paradigm shift in the relationship between physics and mathematics, forcing us to rewrite our textbooks. A must read for anyone deeply concerned about our universe." —Prof. Michio Kaku, author of Physics of the Future

"Tegmark offers a fresh and fascinating perspective on the fabric of physical reality and life itself. He helps us see ourselves in a cosmic context that highlights the grand opportunities for the future of life in our universe." —Ray Kurzweil, author of The Singularity is Near

"Readers of varied backgrounds will enjoy this book. Almost anyone will find something to learn here, much to ponder, and perhaps something to disagree with." —Prof. Edward Witten, physicist, Fields Medalist & Milner Laureate

"This inspirational book written by a true expert presents an explosive mixture of physics, mathematics and philosophy which may alter your views on reality." —Prof. Andrei Linde, physicist, Gruber & Milner Laureate for development of inflationary cosmology

"Galileo famously said that the universe is written in the language of mathematics. Now Max Tegmark says that the universe IS mathematics. You don't have to necessarily agree, to enjoy this fascinating journey into the nature of reality." —Prof. Mario Livio, astrophysicist, author of Brilliant Blunders and Is God a Mathematician?

"Scientists and lay aficionados alike will find Tegmark's book packed with information and very thought provoking. You may recoil from his thesis, but nearly every page will make you wish you could debate the issues face—to—face with him." —Prof. Julian Barbour, physicist, author of The End of Time

"In Our Mathematical Universe, renowned cosmologist Max Tegmark takes us on a whirlwind tour of the universe, past, present—and other. With lucid language and clear examples, Tegmark provides us with the master measure of not only of our cosmos, but of all possible universes. The universe may be lonely, but it is not alone." —Prof. Seth Lloyd, Professor of quantum mechanical engineering, MIT, author of Programming the Universe

"Max Tegmark leads his readers, clearly and accessibly, right to the frontiers of speculative cosmology —and indeed far beyond." —Prof. Martin Rees, Astronomer Royal, cosmology pioneer, author of Our Final Hour

"A lucid, engaging account of the various many—universes theories of fundamental physics that are currently being considered, from the multiverse of quantum theory to Tegmark's own grand vision." —Prof. David Deutsch, physicist, Dirac Laureate for pioneering quantum computing

Editorial Reviews

"Tegmark offers a fascinating exploration of multiverse theories, each one offering new ways to explain `quantum weirdness' and other mysteries that have plagued physicists, culminating in the idea that our physical world is `a giant mathematical object' shaped by geometry and symmetry. Tegmark's writing is lucid, enthusiastic, and outright entertaining, a thoroughly accessible discussion leavened with anecdotes and the pure joy of a scientist at work." —Publishers Weekly (starred review)

"Lively and lucid, the narrative invites general readers into debates over computer models for brain function, over scientific explanations of consciousness, and over prospects for finding advanced life in other galaxies. Though he reflects soberly on the perils of nuclear war and of hostile artificial intelligence, Tegmark concludes with a bracingly upbeat call for scientifically minded activists who recognize a rare opportunity to make our special planet a force for cosmic progress. An exhilarating adventure for bold readers." —Bryce Cristensen, Booklist (starred review)

Contents of the book

This book is my personal quest for the ultimate nature of reality, which I hope you'll enjoy seeing through my eyes. Together, we'll explore the clues that I personally find the most fascinating, and try to figure out what it all means. Here's how I've organized the book:

After two consecutive journeys of exploration, one outward and one inwards, we step back and ask what it all means. We end by returning home and asking what this means for us humans and the future of life in our cosmos, and what we personally can do about it - which is more than one might think!

Videos about the book

Here's a video my wife Meia made where we ponder the book together:
She's currently editing some more that I hope to post here soon.

Frequently Asked Questions
Coming soon!

Coming soon! I'm in the process of collecting together videos, articles and other resources that I find helpful for delving deeper into cosmology, quantum mechanics, and the math-physics link, and hope to start posting them below shortly. I'm also planning a special section for kids which will include my two cents worth of advice if you're young, enthusiastic and want to know what do study and what to do if you want to be a scientist when you grow up.
