# Our Mathematical Universe: My Quest for the Ultimate Nature of Reality

by

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not

That's my girlfriend, who's just been unwise enough to let me read her a paragraph of this book. But our guest K, a local nuclear physicist, is more tolerant. "Well," she smiles, "it doesn't sound so bad. A bit exciting, a bit populistic..." Blah blah blah. On the other hand, she isn't a native speaker of English.

1) I accidentally left it behind at a cafe. When I went back it was gone :(

Imagine my surprise when I discovered some nice person had found the book and returned it to the library for me. Thank you, kind human!

2) Tegmark writes fantastically. Wisely, he doesn't try to make the reader *cough me cough* follow his maths, but instead offers URLs for papers offering the mathematical proofs for the concepts he discusses as ad ...more

**The Mind of God**

It starts with Plato, this idea that the universe is a mathematical expression, populated by objects which are (often imperfect) copies of abstract ‘forms’ (the most perfect of which are numbers), which in turn interact according to strict rules of geometry and aesthetic necessity.* More importantly it was Plato who suggested that things are not what they seem. What we are able to perceive are distorted manifestations of eternal truths which are permanently beyond our grasp, ...more

An unexpectedly deep perusal of the mathematial nature of this baffling world we find ourselces in. Well-written and rich in ideas to ponder on.

Q:

... to me, an electron colliding with a positron and turning into a Z-boson feels about as intuitive as two colliding cars turning into a cruise ship. On microscopic scales, particles schizophrenically appear in two places at once, leading to the quantum conundrums mentioned above. On astronomically large scales —surprise!—weirdness strikes ...more

The Stages of Truth: "Our Mathematical Universe - My Quest for the Ultimate Nature of Reality" by Max Tegmark

Forget about Tegmark’s 4 levels. The stages of truth I can remember are:

• Old Greeks saying "We only see a faint reflection of reality", i.e. we have observation, and that's flawed.

• Old Chinese saying "All we have is observation. Reality is observation, and observation is a function of the ...more

This is a complex and very interesting book, addressing many important questions about the fundamental nature of reality.

The author adopts (and convincingly explains) a particular version of mathematical Neo-Platonism stating that reality is essentially nothing but mathematical structures. His position might be classified as a form of mathematical “monism” (as it essentially denies ontological reality to anything except mathematical objects). From a philosophical perspective, the author can be ...more

*described*by mathematics, but that the universe

*is*mathematics. He calls this the "Mathematical Universe Hypothesis", or "MUH" for short.

Tegmark asserts that this idea is a testable, falsifiable hypothesis. I did not find t ...more

Those interested in cutting edge physics and speculative physics

Before I begin, a brief word about physics from a ninja.

This is a book of speculative physics. At the same time it is a mostly lucid walkthrough of the latest theories in physics. It's important to distinguish between theories and speculation. Theories are directly testable. Results of the theories are repeatable. Special and General Relativity are examples of theories that have been demonstrated over and over again. A result is calculated from the theory, an experiment is performed...the res ...more

Max Tegmark calls his idea the Mathematical Universe Hypothesis, that the external physical reality described by the Theory of Everything is a mathematical structure. He starts off by, I kid you not, assuming that the external physical reality is a mathematical structure.

This radical idea, that reality is "made of math" is embodied in the title of the book, but nowhere within the pages is there ...more

The promise of tying together concepts of modern physics with mathematics and a philosophy of what life and the universe are all about kept me going.

I did appreciate the enthusiasm and energy that Tegmark has for his field. Unfortunately, this came through a bit too often as being full of himself.

When it got to layman's term explanations of quantum physics and relativity, the wording was either too brief or too obscure. I reco ...more

Max Tegmark

Max Tegmark, a physics professor at MIT, is a leading proponent of the idea of the multiverse, familiar to many as the “parallel worlds” of science fiction, but taken increasingly seriously by sober scientific theorists. Several variations on the theme tell us that there must be an infinite number of versions of our Universe (capital “U”), other universes (small “u”), some indistinguishable from our own, some with minor differences, m ...more

This is Max Tegmark's first and only book so far. In the book, Max who likes to be called Mad Max proposes a really "mad" theory of everything called the "mathematical universe hypothesis" in which he argues that the ultimate nature of reality is mathematics. He also argues strongly for the multiverse idea, making it somewhat plausible.

All bad books are alike , each good book is good in its way\s (I think Tolstoy will forgive me for stealing his most famous quote.As the rating indicates, we are in the second state, good book, or rather a fucking unbelievable amazing good and fresh book.

**A Wild Ride With Mad Max**

Alfred North Whitehead famously said that philosophy is a series of footnotes to Plato. Welcome to yet another footnote, as the thesis of this book, in the author’s words, “

*can be viewed as a form of radical Platonism, asserting that all the mathematical structures in Plato’s ‘realm of ideas’ exist ‘out there’ in a physical sense.*” In other words, there is no physical reality, just pure mathematics.

This book is a fun ride for those with a reasonable understanding o“can ...more

This book is an exceptionally eye-opening read containing new, fresh concepts and unbelievable

*{sometimes shocking}*insights. ‘Our Mathematical universe’ covers topics such as

**cosmology**,

**unique philosophy**and

**the nature of reality**. It delves into scientific topics such as ‘the Big Bang’ and the beginning of creation and life itself, to our future and the existence of parallel worlds

**{both sub-atomic and intergalactic}**. This supremecosmology,unique ...more

Unfortunately, those books are rare gems... but this is definitely one of them. Tegmark did a great job at merging physics and mathematics in the most awesomely beautiful and extraordinarily simple way imaginable and I'm so glad I came across this book of his. ...more

*shrug*at you. That doesn’t sell! So it’s not really surprising that

Fantastically interesting, inspiring, and almost comprehensible to this non-physicist, non-advanced-mathematician! Recommended highly if these topics interest you!

First of all, I liked this book (obvious from the rating, right?) But it got me very annoyed a few times.

The right mindset to read this book is to imagine that you met a very cool, very talkative and apparently very smart physicist in a bar. You had a few beers and then dared to say: "Well, tell me about physics... what's that? why do you like it?" Since bar conversations are not super structured, he started with history. "Man, imagine how other ...more

Lately I have been interested in information theory. Reading multiple books on the same subject, there is always the danger of becoming bored. After reading other books on the subject, I read this book and Island of Knowledge by Gleiser at the same time. ...more

There is some useful information here, and MT's book can help the casual scientifically minded citizen clear up some of the confusion engendered by overexcited and ill-informed media reports.

On the other hand, MT's chummy, chatty style is a constant source of annoyance (it's at its worst earlier in the book) and much of the physics is so dumbed down that the broader, speculative portions, in latter parts of the book, start to read like religion.

In summary: if you're interested in understanding ...more
