For people like me working on solid state physics the issues addressed in this book were a recurrent subject to talk over lunch for at least the last decade Someone has to write such a book we used to say necessarily had to be someone from inside write such a book we used to say necessarily had to be someone from inside community I am glad that Dr Hossenfelder did it A theory can be beautiful or not but to use mathematical beauty or naturalness as a guide does not make any sense This book should be mandatory reading for young students I ve always had a suspicion that academics the theoretical physicists are pulling a fast one Sabine has an informative Youtube channel which I follow and bought this book to get detail on some of her topics It or less succeeds although it is a few years out of date regarding the Large Hadron Collider despite being published recentlyThe book details her search around the world to discover if physicists are taking beauty over function when trying to xplain the universe It seems they are although one man s meat is another man s pet Written almost in the form of a diary the style is chatty and asy to digest Diagra According to Sabine most of current physics is a mathematical construct not based on real observations that proposes particles that are fortuitously for those seeking research grants for big physics just beyond what i I have been reading Sabine Hossenfelder s Backreaction blog for a while now Cabaret: A Roman Riddle enjoying her take no prisoners style ofxplaining physics clear and insightful on the science blunt about the process One of the things she is particularly blunt about is the lack of progress in fundamental particle physics with its plethora of predictions over the last decades accompanied by a paucity of xperimental verification So I was xcited to hear she was writing a book about this aspect And what a great book it is both from A Physics And A Process PerspectiveParticle Physics physics and a process perspectiveParticle physics gone nowhere in the last 40 odd years The Standard Model of the 1970s is still the best available despite having known shortcomings The most recent prediction to have been xperimentally verified the xistence of the top and bottom uarks is from 1973 The Higgs boson was proposed in the previous decade Since the 1970s All Roads Lead Home experimental results have succeeded only in disconfirming attempts to improve on the Standard Model Why this stunning lack of progressHossenfelder herself an accomplished theoretical physicist argues it is because physicists are beguiled by the idea of mathematical beauty and are being led astray in their work Rather than being steered by real world data they are following beautiful theories such as string theory down mathematical rabbit holes further and further fromxperimental checks nding up in the bizarre place of having to redefine science itself to allow for the absence of ven the possibility of xperimental validation The book weaves clear xplanations of the problem with snippets of interviews with clear The Mephisto Threat (Paul Tallis explanations of the problem with snippets of interviews with of the physicists involvedHer argument has two main components Firstly theoretical beauty is not a reliable guide There are pastxamples of a beautiful theory having to give way to a less beautiful one when confronted with disconfirming xperimental data And many times the beauty of a theory becomes appreciated or possibly learned only after the theory has been accepted and stablished Secondly physics absolutely has to be grounded in xperimental validation Mathematics is the language used to xpress the theories and like any language you can say many different things in it The only way to discover which if any of these is right is to look to the real worldThis is a great book that will win Hossenfelder few friends in the subject It cuts deep to the heart of the problem in a very accessible manner and Just Cause exposes the groupthink lying at the heart of today s fundamental physics Sabine Hossenfelder is a uantum gravity phenomenologist she links theories toxperiments and observations and she has a popular blog Backreaction She is also losing her faith in physics as it is presently conductedHere is the problem The two great foundations of physics uantum theory and relativity are completely successfu. In this provocative book New York Times a contrarian physicist argues that her fields modern obsession with beauty has given us wonderful math but bad scienceWhether pondering black holes or predicting discoveries at CERN physicists believe the best theories are beautiful natural and legant and this standard separates. .
L to the precision of xisting xperiments and observatio Sabine s asy writing style makes the reading a pleasure She has serious issues with the direction the Particle Physics is headed and is not afraid to ruffle some feathers She approaches the major stalwarts in that area and tries to get their viewpoints across Her discussions make it obvious that the field is pushed forward and ruled by wishful thinking rather than by unbiased vidence based approach She "tries to put forward some suggestions at the nd for the "to put Forward Some Suggestions At some suggestions at nd for the forward Though she does not make it clear she defines search forward Though she does not make it clear she defines search beauty as looking for symmetry unification and naturalness On the whole the book reads like a farewell address to a field she lovesSabine s writing and communication abilities are top notch Even someone who is not well versed in the field can njoy reading the book I highly recommend this to any scientifically curious person Yes she is doubtless a genius but the author makes her point in the introduction The ntire rest of the book is interviews with other geniuses in confirmation Here it is particle physics has become so intractable that new xperiments are near impossible Physicists at a loss for new data use their human imaginations and feelings to guide their Fiesta Moon ever improbable and untestable hypotheses I havenjoyed reading Sabine Hossenfelder s views on her blog before and so I was not completely surprised by this book s premise nor its arguments I was surprised by the interviews This was different than I xpected but uite njoyable Overall I found this hard to put down as Hossenfelder s writing style and the interviews really kept me interested in the book s overall discussionAs a uick summary this is about theoretical physics focusing on particle physics foundational physics and some astrophysics The problem is that there is a lack of new data and so the theorists are using principles other than observation to choose data As Hossenfelder makes clear this is not completely a new or bad problem but in the past new data was around the corner to help clear up which theoretical possibilities to chase Without new observations what principles should be used to come up with new things to research and xplain How do we justify them and if we cannot what should we doThe book is written in an interview and comment style I find that this really works well as I find the comments helpful interesting and put the conversations in the appropriate context I am also uite sympathetic to the arguments in the book As a graduate student in physics though not in the specialties this book focuses in I think I see similar problems of popular arguments and a lack of really thinking about what problems should we be solving I hasten to add that I do not think my fellow physicists are just wasting money and time just that a lot of research does not appear to really be an important step when you think about how it actually contributes to the research program s overall goals Perhaps I have become too much of a pessimist but I fear that a lot of research is being done because it is the type of research that is doneI find the different perspective Hossenfelder offers compared to other general audience physics books to be refreshing and thought provoking It s certainly not an inspiring book but I think it makes a strong point that we should stop and valuate how we are thinking about research so that science can continue to provide us with relevant and xciting new knowledge Sabine Hossenfelder is a physicist with a social media following a much beloved blog an attitude and now a book to go along with it all This is not a physics book it is a philosophy book Its subject matter falls suarely into philosophy of science It is not a book about philosophy of science but a book that does philosophy of science Specifically She mounts a strong critiue of present attitudes and assumptions underlying approaches to today s work in theoretical physics and cosmology Particle physics string theory uantum gravity uantum mechanics and field theory black holes and the origins of the universe all come within her scope In Dr Hosse. Popular theories from disposable ones This is why Sabine Hossenfelder argues we have not seen a major breakthrough in the foundations of physics for than four decadesThe belief in beauty has become so dogmatic that it now conflicts with scientific objectivity observation has been unable to confirm mindboggling theorie.
