A contrarian argues that modern physicists' obsession with beauty has given us wonderful math but bad science.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen

Recommends it for: Anyone who wants to know how science really works
Sabine Hossenfelder is a theoretical physicist, and she's pretty mad about the way her subject has gone over the last thirty years. She's written this book to tell you why she's mad, and what she's done to try and find out what went wrong. She's talked with a bunch of people, some of them major stars of the physics world. She's asked them questions and she reports their answers. Somehow, even though a fair amount of it is near-incomprehensible physics-speak, she makes it cool and funny. She's go ...more

Implausifiability in Physics: “Lost in Math - How Beauty Leads Physics Astray” by Sabine Hossenfelder

“The time it takes to test a new fundamental law of nature can be longer than a scientist’s career. This forces theorists to draw upon criteria other than empirical adequacy to decide which research avenues to pursue. Aesthetic appeal is one of them. In our search for new ideas, beauty plays many roles. It’s a guide, a reward, a motivat

I have no way to judge Dr. Hossenfelder’s qualifications as a theoretical physicist, but I can say up front, she’s one hell of a writer.

I have a bunch of notes, but you know what? If you just want a straight review, go to Steven Woit’s, linked below. My first impressions: theoretical physicists are supposed to come up with stuff that can be tested by experiment. If you can’t test the idea, or if it flunks the test, you move on (see Feynman). Physicists have been working away for *30 years* to tr

A quick summary of the book’s contents: Many physicists these days are inclined to believe that beautiful, elegant theories are the only ones truly worth pursuing. Hossenfelder argues that this is the main reason why there hasn’t been a major breakthrough in the foundations of physics for over 40 years. She asserts that this often debilitating aesthetic criteria has become a rigidly adhered-to dogma, and that physicists are in fact beating themselves soundly with their own outworn yardstick. She ...more

The universe is unacceptable to physicists

Well back into history, Man has tried to force nature into symmetry. Some of our greatest scientists spent their lives trying to force the solar system and then the universe into spheres, cubes, cones and cylinders. Or to find superpartners for every particle so they fit the (newish) theory of supersymmetry. That it has never worked has deterred no one, it seems.

Sabine Hossenfelder is a theoretical physicist whose very job it is to create new theories (

One of my favourite illustrations from a science title was in Fred Hoyle's book on his quasi-steady state theory. It shows a large flock of geese all following each other, which he likened to the state of theoretical physics. In the very readable Lost in Math, physicist Sabine Hossenfelder exposes the way that in certain areas of physics, this is all too realistic a picture. (Hossenfelder gives Hoyle's cosmological theory short shrift, incidentally, though, to be fair, it wasn't given anywhere n ...more

It is reassuring to know that there are quite a few people out there not happy with how physics is going these days.

Reading, for example, Krauss’ half-assed pompous non-explanation for why there is something instead of nothing, or reading Tegmark’s incoherent ramblings about his mathematical universe as he pats himself on the back for being oh such a crazy maverick, or basically watching the entire string community pat their collective backs so hard they will break each other’s shoulder blades

Woit already handled a lot of this in 2007 with [title: Not Even Wrong]. Hossenfelder makes no useful suggestions, instead just dumping on people when she's not flying to Hawaii.

Lost in Math by Sabine Hossenfelder is an important investigation into the current biases shared across the theoretical physics discipline. It asks hard questions about the current orthodoxy. Highly recommended.

Note: I received an ARC of this book from NetGalley.

This was a great book, and one I hope that many people (particularly within physics) choose to read. It's not the most uplifting book, but that's the point. I'm a student within physics, and I'm happy that someone is at least shedding some light on the less appealing aspects of physics at this time. It's great to be hopeful, but if everyone is sharing the same mass delusion about supersymmetry and beauty when there is no experimental evidence f

I honestly don't know how to rate this book. Some arguments were extremely worthwhile and needed a voice. In regard to those arguments, Hossenfelder's voice was razor sharp, clear, unafraid, questioning, critical, and informative. Other times though, it really felt as if she overshot -- a lot, which muddied the waters for her better arguments. Prior to this book, I watched talks given by Hossenfelder in which she picked apart my heroes. She criticized them for being guided by beauty. Watching he ...more

Is truth beauty and beauty, truth? It can be hard to tell.

In Lost in Math: How Beauty Leads Physics Astray, Sabine Hossenfelder argues that these two concepts are not equivalent. As the subtitle implies, Hossenfelder feels that theoretical physicists are too obsessed with creating “beautiful” theories, in the sense that the mathematics that underpins the theories (because these days, theories are basically math, even though, as Hossenfelder stresses, physics isn’t math) must be beautiful and use

A fascinating philosophical take on how philosophical physics has become. Physicists are hooked on various definitions of simplicity, involving fewer mathematical terms and especially fewer "magic constants" or "voodoo constants" (as we would call them computer systems).
The author is having deep existential doubts about how physics will peel back the next layer of reality. Many modern theories not only are not currently being tested, but *cannot* be tested, some because they would involve, oh, s

Wow, great book!

My personality tends to distrust the air of broad, settled certainty when I encounter it; too many times it means the person I'm talking with has made a career or lifestyle out of rejecting competing evidences. If they know the deficiencies in their beliefs, they rarely acknowledge them as such. Examples:

Aug 13, 2018 rated it it was amazing
Like Sabine writes and tries to address, physics has worked itself into a state where all our experiments result in null result after another, and our cutting edge theories are mere speculations of science fiction. The way she approaches this problem, trying to figure out how we got here, what we can do to fix it, and whether what we’re doing is justified in the first place, is wonderful. This is an excellent popular work on the cusp of physics and philosophy, but it comes with a little requirem ...more

A look at high-energy particle physics* in its present nightmare (of deep inconsistency and vastly expensive new data). Her thesis is that the problem is sociological and aesthetic: in the absence of new data sources, we form cliques and regroup around incompatible, unempirical beauty intuitions.
it leads me to conjecture that the laws of nature are beautiful because physicists constantly tell each other those laws are beautiful.

As a corrective to taking theoretical speculations in physics and cosmology too far this book does a good job. It is a lament that using aesthetics in mathematics as a guide to theory is an unreliable guide to science in general. The conundrum is this. The data at the foundations is getting scarcer and scarcer as we push the limits of experiment. Particle accelerators can't reach high enough energies to probe things the way we'd like. With the scarcity of data at the frontier theoretical physic ...more

Thematically similar to Smolin's "The Trouble with Physics" but not so similar as to be uninteresting. Contains some brief excerpts from interviews with a variety of physicists with widely differing views on the relevance of aesthetic principles in cooking up new physics. I found the style informal in a pleasant way, and there was enough technical detail (especially in the notes) for my taste as well.

Sabine shares her experience with physics and math inside a chaotic world where beauty can bright up. She brings a fresh and new perspective to classic theories. This book is a most for new science students. It will encourage them to explore unconventional and innovative paths.

I am keeping tracking the modern books on theoretical physics, like those of Woit, Green, Carrol and others. The mathematics discussion from Sabine Hossenfelder is one of the newest on the block and a very pleasant read. There are three bascis themes in the book that are quite related. First, the lack of progress towards new enhanced theories of elementary physics in the last 20-30 years is described, and how all new measurments confirm the standard model from last century. Secondly is the way m ...more

Brilliant, and an absolutely vital read if you are involved in research in the sciences. The critiques and lessons here extend beyond physics, stretching to the ways we fund, the ways we select for publication, the ways we reward thinking. Too long have these issues been ignored. Too long have those involved insisted that they were free of biases and cognitive distortion.

But lest one think such a book must be a slog, let me set the record straight: this is a page-turner. Hossenfelder keeps thing

I liked Hossenfelder’s book a lot more than I was expecting. Given my expectations, I’m not sure why I bought it in the first place. I was expecting something along the lines of another physicist complaining that other physicists have abandoned empirical testability as the fundamental criterion by which to evaluate theories, and have gone wild with speculative, untestable theories like multiverse theory, string theory, and anthropic theories. And she does complain about that, but she also accept ...more

As an experimental particle physicist and someone who has taught quantum mechanics at the undergraduate level, I am familiar with many of topics discussed in this book, so I am never sure how the average reader will follow it. Given that caveat, I really enjoyed this book. Hossenfelder has misgivings about how some current theories of particle physics are evaluated. Everyone agrees that the definitive test of a theory is how well it predicts experimental data, but what does one do when the theor ...more

I can’t say for sure that I understood everything in this book, since my knowledge of physics in general is very patchy, but overall, I liked its tone, and its global idea, because I can get why one would be easily led astray by theories that look ‘beautiful’. It’s something that I feel is very human, after all, as we often look for a form of harmony in the world surrounding us, if only to try and make sense of it. Perhaps the fundamental, underlyi

Hossenfelder's thesis is that the particular physic community has been led astray by notions of "beauty" and "elegance". She makes a very strong case that regardless of the hardheaded concreteness of the math, the theories that put to the test are theories that physicists explore are chosen by these notions.

The book can get a bit dense...while there is literal or no math, the book involves extremely detailed descriptions of modern physics, particularly in particle physics, so it's not for the fa
