Symmetry and the Beautiful Universe Reviews

    Although it won’t appeal to everyone, as I will explain in a moment, I think it’s fair to say this is one of most valuable popular science books I have ever read. Symmetry is at the heart of much modern physics, but it is generally concealed under the surface, and when it has to emerge, for example when talking about the standard model of particle physics, every book I have ever read on the subject fails to explain the subject properly. This book doesn’t quite make it, but it is by far the closest I have ever seen to a comprehensible explanation.Nobel laureate Leon Lederman (the man behind the dreaded ‘God particle’ term) and his usual co-author Christopher Hill pack a huge amount of information into this slim paperback. We begin with an exploration of symmetry itself, bring in the laws of physics, meet Emmy Noether in some detail and specifically her concept that each of the conservation laws corresponds to an underlying symmetry. From there Lederman and Hill bring in classical physics, and particularly inertia, relativity, broken symmetry, quantum physics, local gauge invariance and QED, quarks and QCD, the standard model and the Higgs field. It is a huge achievement just how much of this they get in, and how approachable most of it is with a bit of work.As that suggests, there is a price to pay for the reader. If you are totally equation averse, you will have problems because there are a lot of them. They are always relatively simple and well explained, but the pages are littered with them (which presents a different problem, as we will discover in a moment). This is a book you will have to work a little bit to read, perhaps occasionally re-reading a section to get the full meaning, but it will be so well worth it.I just have two issues with the book. Although Lederman and Hill almost make the application of symmetry and gauge theories comprehensible there is one huge gap, where the authors say ‘let’s change something to randomly to have any value as we move through time and space.’ They build the whole explanation of gauge theory on this (this is the first book, by the way, I’ve seen that properly explains where that word ‘gauge’ comes in) – yet as presented it makes no sense. They give no reason why we are asked to choose random values, rather than sticking with a smoothly changing value, or making some other arbitrary decision. Because of this there’s a feeling that your understanding is built on sand.The other issue is the quality of the physical book itself. I am very careful with books when I read them – paperbacks usually still look brand new with no creases etc. But by the time I had reached the end, half the pages had come away from the spine. I can live with that, but worse still, the book seemed not to have been proof read. Any book has a few typos or small errors that slip through. You can’t spot everything. But page after page there were equations where a character (often the multiply sign, or the Greek letter phi) was replaced with a question mark. It made them much harder to read, the last thing you need with equations in a popular science book. I can’t understand how the publisher or the authors could fail to spot such a glaring error at the proof stage.Nonetheless an important and hugely informative book on a subject that is at the heart of modern physics but has rarely been comprehensibly explained.

    "لو فكرنا مليا في ما نحاول نحن البشر أن نفعله, سيتبين لنا أننا نحاول بكل ما أوتينا من جهد - ورغم الضباب الذي يكتنفنا - أن نتوصل إلى رؤية كيفية صياغة التناظرات لأفكارنا ومعادلاتنا, وذلك كي تتجسد قناعتنا بأن سحر هذه التناظرات وجمال إيقاعاتها - وحتى عيوباها - سوف تظهر لنا في النهاية - مع الزوال البطيء للضباب - جمال وأناقة الكون الذي نعيش فيه."قبل قليل أنهيت قراءة الملحق في نهاية الكتاب, وكان بعنوان :(الزمر التناظرية المستمرة ) وفكرت كيف بحق الجحيم وصلت إلى هنا ؟! قبل قليل كنت أقرء عن الموسيقى والأساطير القديمة . حسنا أنا لا أعرف كيف بالتحديد وصلت إلى هنا لكن بالتاكيد لقد كانت رحلة ممتعة بشكل لا يوصف . وهذا ملخص سريع لما حدث -تقريبا - :بدء الكاتبان في المقدمة بالحديث عن التناظر وعن جمال التناظر في الفن والموسيقى. ثم أنتقلت الأحداث الى الحديث عن كوكب الارض والصراع الطويل حول هل تدور حول الشمس والعكس وهكذا ... .ثم أنتقلتَ إلى إيمي نوثر العالمة الرياضية المجهولة التي عززت مفاهيم التناظر في العالم الحديث *في الفصل الأول تكلم الكاتبان عن تكون الكون والأساطير حول ذلك في الحضارات القديمة. ثم تقدموا في الكلام كيف أن القوانين التي تحكم عالمنا هي نفسها في كل زمان ومكان .*الفصل الثاني كان تتمة للفصل الأول وحاول أن يعزز مفهوم ثبات قوانين الفيزياء في كل مكان لكنه ركز على الطاقة ومفهوم أنها لا تفنى ولا تستحدث .* عدنا في الفصل الثالث إلى العالمة المغبونة أيمي نوثر وأسهاماتها في الرياضيات والفيزياء وخصوصا مفهوم التناظر, وكذلك حياتها وأرتقائها في سلم المراتب العلمية . *تكلم الفصلان الرابع والخامس عن التناظر بشكل مفصل وخصوصا التناظر عبر الزمان والمكان و الحركة والطاقة والمفاهيم الفيزيائية المرتبطة بهذه المفاهيم. *تناول الفصلان السادس والسابع مفاهيم العطالة والثقل والنسبية لأينشتاين وعلاقتها بالتناظر .*وفي الفصول الثلاث الاخيرة تناول الكاتبات قوانين الفيزياء التي تحكم الكون وتناظراتها على مستوى عميق جدا . تطرق الكاتبات إلى الجسيمات الدقيقة التي تشكل الكون وعوائلها وكيفية تشكلها وعلاقتها بنا بصورة مباشرة أو غير مباشرة .----------------------------أن هذا الكتاب على الرغم من حجمه الكبير نسبياٌ, ألا أنه كتاب ممتع ومسلي ويحوي الكثير من المعلومات عن الفيزياء على عكس أغلب الكتب التي تخاطب غير المتخصصين التي تكرر نفس المواضيع من تشكل الكون والجسيمات الدقيقة الخ . هذا الكتاب يقدم رؤية أبداعية ومحاولة جديدة لفهم هذا الكون وتغيير نظرتنا ألى الكون .أخيراٌ رغم أن الكتاب لغير المختصين ألا أنه أحتواى مقدار كبير نسبياٌ من الرياضيات والتي تحتاج إلى بعض الدراسة لفهمها . رغم بساطته ألا أنه كتاب موجه للعامة الذين يحبون الفيزياء ويتحملون ثقل الرياضيات لأجل محبوبهم .

    مدهش كيف استطاع المؤلفان تلخيص أهم النظريات والاكتشافات الفيزيائية في هذا الكتاب بأسلوب بسيط وممتع. التناظر، الانعكاسات، النسبية، ميكانيكا الكم، الجسيمات الأولية وعلاقة الرياضيات بالفيزياء ونظرية الأوتار وغيرها. بعض تفاصيل التجارب لم أفهمها، لكن الكتاب عموما ليس صعبا على غير المختصين -مثلي-.

    Oh I'm so annoyed by Lederman that I must trash this book before letting it quietly sneak in my book shelf. Ok, so firstly, I was deceived by the pretty cover (ok, I do judge books by their covers) and secondly, Amazon says Lederman's "the most engaging physicist since the much-missed Feynman." Comparing Lederman with Feynman in terms of wit and idiosyncrasy? Rubbish. Lederman wrote this book as if he really didn't care about what he was writing (sort of like the person writing this review). My expectation value of the quality of the bookfluctuated in the first 100 pages, then exponentially decayed in the next 100, and where are we? ,Is light a particle or a wave? (ugh), then it dropped down to negative infinity. he jumps from one topic to the next, struggling to find (and often comes up with stupid) analogies for simple principles like conservation of momentum, energy. And then chucks in random stories about some scientific giants whohave little to do with the story flow. The entropy of the book follows closely with the second law of thermodynamics: only goes up. or maybe Lederman wants to use the incomprehensible structure of the book to demonstrate the state of nuclear physics before Gell-Mann: messy, random, and basically no one knows what the heck is going on. and i bet he must crack his brain too hard to be funny. But hah, he manages to make me laugh once when he talks about the husband-wife paradox, when the wife comes back on a spaceship: "when they meet upon her return, indeed he has aged 20 years, and she two weeks. Like wine, however, this did not dampen the enthusiasm, even though it slightly diminished the performance". But that's not very physicsy is it? honestly, i felt like i wasted time reading the first 200 pages without really learning anything new, and bam when it hits the mostprofound concept of the book, gauge symmetry and SUSY, Lederman seems to just drop dead, jumbling words in a few pages and moved on to a new (but boring) topic. this book stands as empirical evidence that great scientists can write absolutely whacky books.

    The authors describe the backbone of physics through a variety of symmetries, translational, rotational, continuous time symmetry, symmetries of constant movement, gauge symmetries... all through the lens of Emmy Noether's theorem that for every continuous symmetry there is a conserved property. Translational symmetry, for example, leads to conservation of momentum, that of time to conservation of energy, gauge transformations to that of charge. The book starts out describing Newtonian mechanics in this fashion before moving onto relativity (symmetry for constant velocity frames and one between acceleration and gravity), then onto quantum mechanics, the structure of the atom and the world of the standard model and the rules of color charge. All of this is fairly well tied together through the central thesis of symmetry seeking, and ends by explaining how symmetry breaking is actually necessary for our universe to be as it is. If it weren't for some kind of symemtry breaking between matter and anti-matter, for example, we'd never get the clumpy matter that is necessary for the evolution of life. If it weren't for the higgs mechanism causing symmetry breaking, some particles coupling more strongly to the higgs field than others, particles would not acquire mass. Overall this was an enjoyable read, deeply explaining rules of physics that might appear to otherwise be arbitrary (such as conservation of energy), through a rather simple idea.

    يناقش الكتا أحد أكثر الظواهر العلمية انتشارا في الطبيعة وهي ظاهرة التناظر ،تمتاز مقدمة الكتاب بأسلوب رشيق ومشوق حيث يعرض ليون وكريستوب أفكارهما في تسلسل واضح يسهل على القارىء البسيط فهم مايريدا قوله تعود فكرة التناظركمفهوم علمي الى طفولتنا جميعا ، عندما نتأمل قرصي الصدف المتطابقان تماما أو جأوراق الاشجار أوحتنى التناظر الصوتي في نقرات الطبل أو زقزقة العصافير العفوية كلنا في الحقيقةكما يقول المؤلفان شهود عيان على وجود التناظر في حياتنا ماهو التناظر التناظر هو أن تبدو الاقسام المختلفة من جسم كما لو كانت هي نفسها مثل حالة الاذنين ،والعينين ،التناظر هو التعبير عن التكافؤ بين الأشياء عندما يكون الشيئان هما الشيء نفسه ،وفي الرياضيات يستخدم الرمز الشائع = للدلالة على ذلك وهو تعبير عن التساوي بين الأشياء وهذه الاشياء قد تكون أجساما مختلفة أو أقساما متباينة من الجسم نفسهتحدث المؤلفان عن التناظر في مجال مألوف للجميع وهو التناظر في الموسيقى ! نعم الموسيقى وان كانت ليست منالأمور المرئية فكما عرف المؤلفان التناظر هو موجود في كل مكان وخاصة في الفنون وهذا يشمل أحد تجلياتها وهو الموسيقى

    يتناول الكتاب عدة مواضيع اساسية في الفيزياء مثل التناظر و العطالة و النسبية وميكانيكا الكمّ و الكواركات و و يفرد جزءاً كبيراً منه للاحتفاء بالرياضية إيمي نوثر و نظريتها.الكتاب صعب و هناك اجزاء كثيرة لم افهمها, لا يمكنني ان اعتبره كتاباً جيداً للغير المتخصصين في الفيزياء او للراغبين في كتاب فيزيائي سهل و مبسّط.

    In my continuing quest to understand the world of theoretical physics, I found this to be an enlightening book. It provided a new perspective that helped me to better understand things I have read in the past.

    HIGHLY RECOMMENDED!Many quantum physichs books deal with the most common topics as wave-particle duality, higghs field, forces, etc, and conceptually they do it really well!However, you wont get the completely closure feeling of the issues because they dont explain symmetry and if they did, it would be lacking. Due to the fact that authors write having in mind the theme they would like to develop and explaining in great detail symmetry and its consequences should defenitely be reserved for another ocassion or more likely an entire new book. So yes, reading about symmetry is a good choice.Lederman's and Hill's book is astounding and clarifying. You will learn a LOT from it.There are formulae inside and that's what makes the book even better.I can't complain really, I liked the contents and don't find them to be nonrelative as some people expressed. Nontheless, if I had to say something negative I would go for the paperback editions quality as Brian Clegg already remarked( my poor book ended up splitted in two, on one hand the cover and on the other hand the papers).

    "Three quarks for Muster Mark". Symmetry is an Alice in Wonderland adventure, jumping down rabbit holes from parsecs and arcseconds, to quark jets and gauge bosons with each onion like layer being more complex and fantastic than the one before. Lederman traces the development of quantum theory from its meager beginnings in the early 19th century to the Large Hadron Collider operating today in CERN. Engagingly written and in plain enough language to make ones inner physicist jump between orbitals. This is a must read especially for those interested in how electromagnetism, quantum chromodynamics, gravity and the weak force of the standard model all hold this place of ours together. Symmetry proves to be key in unlocking the universe and will leave you with a Cheshire Cat grin.Give a person enough superstring and they will hang themselves.

    Worthwhile pop-level intro on the importance of symmetries in physics. My favorite sections were the initial chapters that outlined Noether's theorem, space-time symmetries, "Gedankenlab", as well as the (lightweight) mathematical appendix explaining symmetry groups. The remainder of the content (encompassing relativity, gauge theories, Feynman diagrams, and quantum mechanics) was also interesting, even if chapters felt mostly disconnected from each other.Much of the content was presented only at a very high "here's a thing you should know about" level. I don't expect to be an expert after reading a pop level book like this, but I was hoping it'd take a slightly deeper look at some areas where I want to learn more (eg: I still only kinda-sorta understand the notion of what gauge theories actually are, despite a decent number of pages dedicated to talking about them).

    A mixed bag really. While there were parts that were genuinely fascinating, particularly regarding particle physics and the unification of the forces, a lot of the time the link between what was being discussed and the concept of symmetry seemed a little far-fetched. On a positive note, the book required little prior knowledge to understand although I did find that the difficulty level varying quite dramatically in places; the authors would go from a very, very basic look at momentum straight into a rather more complex derivation of general relativity. I was encouraged by the interesting first 100 pages, but by the end, I must admit it was becoming a bit of a drag to finish the thing...

    What do the laws of nature have in common with music and art? They all obey the mathematical principle of symmetry, according to Nobel Laureate Leon Lederman and theoretical physicist Christopher Hill. Symmetry is a principle underlying much of fundamental physics, and Symmetry and the Beautiful Universe explores this concept in various modern day theories in physics, while attempting to convey a sense of its beauty. It also contains a short biography of a very interesting but relatively unknown female mathematician called Emmy Noether and her work in this field.

    Excellent book on the current state of the art of particle physics. Very easy to comprehend. There aren't a lot of mathematical formulas (actually, I thought there could have been a bit more rigorous math outside of the Notes). I really like how the authors stressed the importance of Emmy Noether's contributions to modern quantum theory. She's not a name that enough recognize, but she does belong in the pantheon of Einstein and Newton.

    All I got from this was what I went in with: symmetry is a powerful intellectual model for understanding the relationship between apparently-different phenomenon, such as electricity (on the one hand) and nuclear binding (on the other.) I read it twice because I really wanted to get it. That helped with my understanding of how inertia can be understood, but really, I had that already. Do I sound disappointed? Yeah.

    ربط المؤلفان ما بين التناظر الرياضي وما نعرفه عن العالم الفيزيائي، بدءًا من أرسطو وفيثاغورس حتى غاليلو ونيوتن وأينشتاين وصولًا إلى التناظر في العالم الكمومي وما تطمح نظرية الأوتار الفائقة أن تحققه؛ مما منحني فهمًا أفضل وتصورًا أوضح للقوانين الفيزيائية الكلاسيكية والحديثة. أنصح بقراءته للمهتمين خاصةً بأن معظم الكتاب إنشاء أدبي مما يجعله سهل القراءة.

    Interesting book for technical readers. The last few chapters are somewhat mathematically oriented and may be harder for high school or freshmen students. If they do then they are highly eligible to enter the field of particle physics and work in the LHC at CERN.

    The focus of this book is more on physics than on the mathematics of symmetry.The author is an eminent Nobel Prize winning physicist who really knows what he's talking about, and it's a very good read. Lederman's humor and ego both come through.Highly recommended!
