Our Mathematical Universe

Posted on 27 August 2017 by Max Tegmark

Our Mathematical Universe is a journey to explore the mysteries uncovered by cosmology and to discover the nature of reality Our Big Bang, our distant future, parallel worlds, the sub atomic and intergalactic none of them are what they seem But there is a way to understand this immense strangeness mathematics Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea that our physical world not only is described by mathematics, but that it is mathematics This may offer answers to our deepest questions How large is reality What is everything made of Why is our universe the way it is Download Our Mathematical Universe author Max Tegmark – kino-fada.fr Aaargh No Make it stopThat 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, istolerant Well, she smiles, it doesn t sound so bad A bit exciting, a bit populistic Blah blah

Max Tegmark s chatty, informal, slightly manic style is on the irritating side, and if you know some physics it may also give you the impression that you re not going to learn anything from Our Mathematical Universe Unless you re working at the cutting edge of the subject, that impression is almost certainly false When I briefly explained the content to K,...I have three things I d like to say about this book.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 additional reading, for th I have ...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

of material, topics ranging from astronomy, cosmology, and quantum physics, to farprecarious stuff such as the level IV multiverse and the Mathematical Universe Hypothesis, which Tegmark champions rather emphatically In the beginning of the book page 13 , he includes a helpful diagram that clearly states which chapters are considered mainstream, controversial and even extremely controversial He

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 This is a complex and very interesting book, addressing many important questions about the fundamental nature of reality The author adopt...The first half of this book is a review of modern physics on the macro and micro scales The second half of this book is a discussion of the author s speculation, that the universe is a mathematical

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...The thesis of this book is nothing but a giant exercise in circular reasoning.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 any logical argument in The thesis of this book is nothing but a giant exercise in circular reason...The title makes one feel this will be a daunting read and at times it is, but Tegmark starts out in a clear concise fashion reviewing current cosmological concepts He provides detail on mapping the cosmic microwave background radiation including his own considerable involvement He describes how it mirrors our present day universe which maintains the background radiation s uniform temperatures and densities This leads to Alan Guth s theory of inflation which explains the uniformity, flatness a The title makes one feel this will be a daunting read and at times it is, but Tegmark starts out in a cle...This book starts with solid science on the advancements of cosmology in the early part with a solid scientific description of the Big Bang model and getsspeculative afterwards If you don t like to indulge in theoretical and philosophical speculation the latter part of the book might not be for you If you are like me and relish in some deep speculation about the nature of the cosmos even if the data hasn t backed it yet then read this book it is great at that Tegmark explains in a relat This book starts with solid science on the advancements of cosmology in the early part
