The mathematical structure that Tegmark sees as the instantiation of the physical world is one that has been found to be riddled with paradoxes and proven to be incomplete. Max Tegmark in Our Mathematical Universe is informative, chatty, and engaging. . The book has many interesting and counter intuitive thought experiments, scenarios. His concluding chapter on the risks humanity faces is wise and bracing: he believes we "are alone in our Universe" but are capable of tackling terrible threats from cosmic accidents, or self-induced nuclear or climatic catastrophes. Though the author exhibits humor and high self-regard, there are instances where the difference between the two remains unclear. Book Review: Our Mathematical Universe, by Max Tegmark. The mathematical structure that Tegmark sees as the instantiation of the physical world is one that has been found to be riddled with paradoxes and proven to be incomplete. Also Tegmark doesn't point us towards any practical outcomes of the theories described, apart from a final chapter on how unique and fragile we may be in the multiverse, and how we need to protect our future from existential threats (with the techie favourite AI enslaving us all as the favourite threat). It also analyzes reviews to verify trustworthiness. Want an ad-free experience?Subscribe to Independent Premium.

An excellently written and intellectually absorbing book that deserves to be read slowly, carefully and again and again. “This is science writing at its best—dynamic, dramatic and accessible. This chapter leaves the reader to wonder just what’s going on in the author’s mind and leaves the impression of non-sequiturs standing in for well-reasoned thought. I'd really like to have read some more predictions about where current experiments around gravity waves and Higgs bosons might lead. Reviewed in the United Kingdom on May 6, 2019. It's a truly remarkable fact that our deepest understanding of the material world is embodied in mathematics, often in concepts that were originated with some very different motivation. Having stretched our minds to encompass forbidding concepts of mathematically plausible universes, in the last chapter he comes to the old-fashioned humanist conclusion that there is no point looking for uplift and moral guidance in all this: "our Universe does not give life meaning but life gives our Universe meaning". It is supposedly a popular science book about Cosmology, which to a large extent it is. Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians. Why does mathematics explain the universe so well? Your recently viewed items and featured recommendations, Select the department you want to search in.

The mystery then, as posed by Stephen Hawking, is “What is it that breathes fire into the equations and makes a universe for them to describe?”, This is not an easy read, but well worth the time, Reviewed in the United States on October 22, 2015. Please try again. Tegmark’s answer is because the universe is fundamentally mathematical—or at least he suspects it could be. Unable to add item to List. Many cosmologists don’t like the anthropic principle as it suggests the universe was created by accident or by God  (hence the book’s title: Our Accidental Universe). It is no longer science but speculations from the author, some of them quite interesting, into philosophy and his belief (hence the title of the book) that our Universe is a mathematical structure, rather than something that can be explained with mathematical structures. It is quite an adventure with many time-outs along the way. The first level universes would have the same laws of physics that exist in ours, though most of these would not have life or galaxies or stars or planets. He adds, “If I’m wrong and the MUH is false, then physics will eventually hit an insurmountable roadblock beyond which no further progress is possible.”. This is simply wrong, and he should know that mathematical logic presupposes the natural numbers' structure, for example to make inductive constructions/proofs.
