    I really enjoyed the explanations given in this book. The author is Einstien but the writing is Infeld. He worked very closely with Einstien.They begin with basic mechanics and work their way through field physics, special and general relativity and then finally to quantum mechanics. All of this is done without mathematic equations. It is all explained through analogies, theories and explanation or real world experiments. It is a very interesting read if for no other reason than to see the development of the theories and how their minds made each transition.I have a personal interest in these areas but no actual education. I really like a book like this that makes it much more understandable to the average Joe.Unfortunately it is dated at this point. There has been many further advancements in both quantum physics and in planetary. They do an excellent job of laying a foundation for further study. This is probably a good book to read before reading Stephen Hawking's "A Brief History of Time."

    This book is so polite! Written in 1938, apparently more by Infeld than by Einstein, it is exceedingly proper and therefore delightful, as well as thorough. It is a beautiful book, very clear and precise, and should be read by all armchair physicists with a serious hankering to understand relativity theory, as well as the importance of the quantum theory.

    نحن لا نستطيع أن نبنى علما دون أن نعتقد بإمكانية إدراك الحقيقة من خلال منشآتنا النظرية ودون أن نوقن بوجود تناغم داخلى في العالم الذي نرصده. إن هذا الإيمان كان وسيظل الباعث الرئيسى لكل إبداع علمي. فمن خلال كل مجهوداتنا، نلمح الطموح إلى الفهم والايمان الراسخ بتناغم عناصر الوجود ، ذلك الايمان الصامد أمام كل العقبات التى تحول دون إدراك الحقيقة.

    Bu kitabı 1995 civarında arkadaşım İnanç'tan almıştım ve o zamandan beri Ankara'da annemlerdeki kütüphanede bekledi. İlk okuduğum popüler bilim kitabı Carl Sagan'ın Kozmos'unu da ondan almıştım ama bu kitabı bir biçimde okumaktan korktum. Bu yılbaşında gözüme ilişince sahibine geri vermek üzere aldım ve okudum. Birçok yerinde FL'de öğrendiğim konuları anımsamak ve o zamanlar anlamadığım bazı şeyleri anlamak güzel olduysa da, hâlâ ilişkinlik/görelilik/relativite kuramını anlamış değilim. Parçaçcık/kuantum fiziği konusunu da geçiştirmişler gibime geldi. Ama bu iki büyük bilim adamının oturup bizlere böyle açıklayıcı bir kitap yazma işine girşimiş olmaları takdire şâyân. Çeviri de çok güzeldi. Sonunda verilen bazı kavramların Türkçe ve Osmanlıcasını veren sözlüğün fotolarını çektim. İstatistiğe sayılama deniyormuş. Biraz daha bilimsel kitap okumaya karar verdim.

    Einstein has a reputation not only as a physicist, but as a humanitarian. The clarity and style of this book reinforces the reputation.Slowly, carefully and with great concern that the reader not be left behind, Einstein and his co-author tell what could be a bewildering tale by demonstrating how the science of the physical relationship of things evolved.It did so for the reason that all science evolves: questions, in being answered, pose further questions. The pursuit of the unknown, with the necessary condition that it be followed regardless of the danger it poses to accepted thought, takes the mind onward, but at the expense of the familiar.This is THE reason for conflict between science and religion. The former says - I want to know the truth, regardless of the effect on what I believe to be true. The latter says - I know what I believe, it is the truth and I don't need to know more. Science is impatiently looking forward, religion is at rest and content. Science finds mystery intolerable, religion treasures it.Without a single mathematical equation, Einstein presents the established thought about the relationship between things from the time of Galileo up to quantum mechanics at the time the book was written in 1938. He demonstrates why each view of the world was so convincing.It made so much sense early on to think that the world was made up of particles that simply interacted with each other by force. Newton showed that some object would remain motionless unless it was acted on by another, moving object. The apple and the moon worked under the same assumption.All was well but light presented a problem. We know that sound passes by way of pressure through a medium, air, from the source to our ear. Take away air and there is no sound. So how can we see? What is the medium through which light passes to reach our eyes? It was assumed that all of space was filled with "ether" through which light, like sound in air, passed.Science, while loving to find a mystery, hates it's persistence, so the presence of ether was something that demanded experiments to prove. In following the pursuit of ether, Einstein is at his best explaining the concept and exactly why it was thought necessary, referring back to sound and even further back to objects subject to forces acting on them.Throughout the book, the theory of relativity is never far from view. The whole body of science up to the introduction of relatively assumed a fixed reference for all of creation. A straight line could be continued in one direction forever. You and I could always agree on the speed of an object, like a train, even if I were watching the train and you were traveling on it. Every point on earth and every planet could be imagined in three dimensions at a specific time. The universe was an elaborate mechanism that ran like a clockwork.What Einstein discovered is that there is only one thing fixed, the speed of light. This became the standard to which all other references must bend. Time could almost stop, the length of a piece of pipe could lengthen or shorten, an object could change its mass, all of these relative to the speed of light, constant everywhere and for all observers.Relativity, standing firm under all tests designed to disprove it, has upended our confidence in our senses. Though relativity doesn't forbid, in fact, confirms the world of our daily experience, it resolutely rejects the application of daily experience to the larger reality. Mass and energy are interchangeable, the force of gravity and the force of acceleration are identical, light is both a particle of energy, the photon, and an electromagnetic field.From being the center of the universe, man has been successively diminished, first in our place among the stars and now in our confidence that what we know from sensation is absolute. Only in the abstract world of mathematics can we continue the pursuit of truth, but in that lies the rescue of our worth. Only we can know the truth, all else stands dumb in an uncomprehending universe. Small potatoes, yes, but small potatoes that think!Einstein had the determination to push beyond the accepted, yet even he was challenged by quantum weirdness. Others have taken up where he left off. This book will pull you along to an understanding not just of relativity, but of the reason science holds such allure.After you've read this book, I highly recommend to you Max Tegmark's "Our Mathematical Universe", which I have also reviewed. Tegmark takes Einstein's relativity and runs with its implications beyond the known universe known to astronomy.

    Interesting book. Most of it was written by Leopold Infeld who was a colleague of Einstein and a fellow refugee from Europe. Infeld could not get a permanent appointment at Princeton due to a bitter rivalry within the Physics department so he came up with the idea of writing a popular, non mathematical monograph explaining the history of physics. Einstein readily agreed and this allowed Infeld to obtain a secure source of funding. Einstein's name appears first only because his was the better known of the two.Infeld tried to compare the evolution of physics to a detective novel where one follows "clews" to arrive at the hidden truths. The first half of the book deals with the rise and fall of classical mechanistic physics starting and the last half with relativistic and quantum physics. Since the book was written in the 30s it does not contain any of the newer theories on such things as string theory, multiverses etc. I do not miss these as they are not supporeted by "clews" at the present time and while they are attempts to build on and unify Einsteins fundamental explanations of the construction and working of the universe they are not verifiable at this time by any experimental techniques and remain solely in the realm of mathematical hypothesis.

    تاریخ علم فیزیک از زبان اینشتین شنیدن دارد. این کتاب به ما می‌آموزد که مفاهیم علمی به چه شکلی در مواجهه‌ی ما با طبیعت و برای فهم بهتر آن تولید می‌شوند و رشد می‌کنند. ضمنا نظریات فیزیکی در همین دویست سیصد سال اخیر چقدر عوض شده‌اند و در یک روند رشدی چقدر از مفاهیم و نظریات به کناری ریخته شده‌اند.این کتاب برای آشنایی مفهومی و فارغ از ریاضی با نظریات فیزیکی از زمان نیوتن تا زمان خود اینشتین هم خوب است.نکته‌ی جالب این که حتی یک نام هم از اینشتین در این تاریخ نویسی نیامده در صورتی که می‌دانیم اینشتین در همه‌ی فیزیک جدید حضور دارد.

    Absolutely awesome! In my mind, this book is more about psychology or cognition rather than physics. I love books whose plots are connected by logic rather than irrelevant story telling. More precisely, this book is about how human "create" knowledge and the nature of reality. There is in fact no force, no field, no charge. All we have is motion, along with, at best, the tendency of motion. The "scientific" concepts are artificially created to, and only to, classify unrelated events that only make sense to your corner case reference system. It is not knowledge itself but only the form of evolution of knowledge can give us a hit of reality. well..that's just my interpretation..maybe I'm wrong but this is definitely the book you have to read if you're desperate to understand physics or mind..or are they different? :P

    This book is a pretty good explanation of the history of physics, from Galileo to quantum theory. It is set out in a fairly comprehensible manner, and there are a lot of analogies used. This isn't going to help you much with exams but it's a great way to get your head round the overall structure of physics.

    I first picked this book up thinking that it would provide a broad overview of the entire history of Physics. I really wanted Einstein's take on Aristotle, Lucretius and maybe even the pre-Socratics in a sweeping history of scientific thought. On this account, I was sorely disappointed. Einstein summarily dismisses all physics prior to Galileo, and I almost summarily dismissed the book as a result. It sat on my shelf for about two years until I recently picked it up thinking I needed a new way of seeing the world after having immersed myself in historical and cultural studies over the last few months. I am glad I picked it up again. This is a really good book. It is not only good because Einstein is a master at explaining complicated physics in a way that a layman like I am can understand; the book is also good because Einstein gives a compelling portrayal of the creativity, thought experiments and testing involved in a scientific approach to reasoning. It is this latter part that I greatly enjoyed. Essentially, as Einstein explains it, modern Physics is a way of looking at problems, testing them and resolving them through scientific theory. However, each time scientific theory solves a problem, it creates a new set of problems that furthers scientific inquiry. As a result, mechanical physics gives way to field theory which gives way to relativity which leads us to quantum mechanics. In each step of this intellectual journey, some ideas are discarded by the new theory, but others are more fully explained and understood. It is an exciting process, and in the book's portrayal I really came to appreciate the perspective and the discipline of scientific reasoning. This is a great book for anyone whose interest in pop culture science has lead them to pick up Greene's Elegant Universe and similar popular explanations of physics and science.

    هذا الكتاب رغم قدمه ولكني استمتعت كثيرا بقراءته واستفدت أكثر ، أنا لا أعلم مدى مشاركة تلميذ أينشتاين في الكتابة ولكني أستطيع ان أرى أسلوب أينشتاين في الشرح وإيصال الفكرة بكل موضوعية ، فقد بدأ بشرح تطور علوم الطبيعة منذ جاليليو وحتى ميكانيكا الكم وبداياتها على عهده ، وقد فعل ذلك بكل حياد وموضوعية دون أن يحتقر أو يتجاهل قوانين نيوتن والمياكنيكا الكلاسيكية بشكل عام ، بل أكد على أهميتها وعلى أن النسبية سواء العامة أو الخاصة ماهي إلا تعميم للميكانيكا الكلاسيكية ورؤية أفضل لعلوم الطبيعة ، وأسلوبه في إيصال المعنى والفكرة جميل جدا وبسيط دون تعقيد وهو ما يقال عليه السهل الممتنع ، أنصح بقراءته لكل من يريد أن يعرف كيف ظهرت النسبية ولماذا ومدى تغير نظرتنا لقوانين الحركة والجاذبية وغيرها من قوانين ونظريات علوم الطبيعة بعد النسبية وميكانيكا الكم ، ولكن لا شيء مثالي للأسف ، النسخة التي قرأت الكتاب منها وهي نسخة المركز القومي للترجمة ، ذات ترجمة سيئة إلى حد ما وجعلت فهم الكتاب صعبا وهذا ما جعلني أتاخر في إنهاء قراءته ، وكذلك طباعة الكتاب سيئة جدا ، ليتني أجد نسخة أخرى لهذا الكتاب الرائع لألبرت أينشتاين وتلميذه ليوبولد .

    An accessible, straightforward journey through the rise and fall of various theories at the heart of physics, from Newton's time to the early 20th century era of Einstein and Infeld. Although "rise and fall" is not quite accurate; the authors stress that new theories tend to broaden the scope of the old theories rather than upending them entirely. Thus, for example, today we freely make use of Newtonian mechanics when dealing with non-relativistic speeds, or use Maxwell's equations when the electromagnetic field in question is large enough to obscure small-scale quantum effects.This is a popular science book, and an extremely good one. The authors make heavy use of analogy and thought experiment, ideally chosen for both easy understanding and the way they accurately crystallize difficult concepts. Even if the reader has a firm grasp of the history of physics, this quick read also offers itself up to would-be science educators as the epitome of good pedagogy.

    This book offers two things:1. A summary of physics, from classical mechanics, to field theory, general relativity and quantum theory (as it was understood in 1938 when the book was first published). The presentation is oriented towards laymen and avoids using any mathematical formulas. The explanations of the basic ideas of physics are marvelously clear and straightforward. However, the self-imposed strict avoidance of math, although probably appealing to the wide audience, sometimes resulted in vagueness that left me unsatisfied. 2. A pioneering glimpse into a new epistemology that was later expanded by Thomas Kuhn into his famous theory of scientific revolutions via paradigm shift. Indeed the basic ideas of that theory are clearly presented here by Einstein and Infeld almost a quarter-century before Kuhn's seminal "The Structure of Scientific Revolutions" was published.

    "da Teoria da Relatividade,depreende-se que massa e energia não são senão manifestações diferentes do mesmo fenómeno,um conceito pouco familiar para uma inteligência comum.Explicando a equação E igual a mc ao quadrado,na qual a energia é igual à massa multiplicada pelo quadrado da velocidade da luz,mostra que pequenas quantidades de massa podem ser convertidas numa grande quantidade de energia,e vice-versa.A massa e a energia são,de facto,equivalentes,de acordo com a formula mencionada.Isto foi demonstrado,experimentalmente,por Cockcroft e Walton,em 1932".

    "Các bộ sách về vật lý luôn đầy ắp các công thức toán học phức tạp. Nhưng khởi nguồn của mỗi lý thuyết vật lý đều đến từ sự suy tư, từ các ý tưởng chứ không phải từ những công thức. Sau đó, các ý tưởng này phải được diễn đạt dưới hình thức toán học của một lý thuyết có tính định lượng để có thể được so sánh với thực nghiệm." - Albert Einstein & Leopold Infeld, trích "Sự tiến hóa của vật lý".Đây là một quyển sách tuyệt vời, vẽ nên một bức tranh toàn cảnh về quá trình tiến hóa của Vật lý. Từ những ý tưởng cơ bản, xây dựng nền móng như tư duy cơ học, trải qua quá trình đấu tranh và thống nhất giữa các mặt đối lập, quá trình kế thừa và giải quyết các cuộc khủng hoảng phát sinh từ những bất cập trong lý thuyết cũ, những lý thuyết mới dần được sinh ra và phát triển dần tới ngành Vật lý lượng tử như ngày nay. Đây chính là những nỗ lực không ngừng nghỉ của trí tuệ con người nhằm mô tả hiện thực chúng ta mà tri giác được ngày càng giống với bản chất của tự nhiên. Quyển sách cũng cho thấy mối liên kết logic giữa các lĩnh vực cơ, nhiệt, điện, quang trong Vật lý cổ điển với thuyết tương đối (rộng và hẹp), Vật lý nguyên tử và hạt nhân, cơ học lượng tử trong Vật lý hiện đại. Tác giả cũng chỉ ra những điểm tương đồng và tương phản giữa chúng tạo nên một cái nhìn tổng thể về vật lý học.Điều đặc biệt biến một quyển sách bàn về bộ môn khoa học từng là nỗi ám ảnh của nhiều người trở nên dễ hiểu, mạch lạc, chính là sự giản lược tối đa các công thức toán học trong vật lý. Bằng lập luận chặt chẽ, mô tả cụ thể, sử dụng các thí nghiệm tưởng tượng trên nền tảng logic, các hình ảnh minh họa trực quan, nhiều ví dụ và ẩn dụ sinh động, tác giả đã thành công trong việc dẫn dắt người đọc chứng kiến từng bước khởi đầu và phát triển của ngành Vật lý học. Cuối mỗi chương đều có phần tóm tắt những kiến thức trọng tâm để làm nền tảng cho chương tiếp theo. Muốn xâu chuỗi toàn bộ nội dung cuốn sách, bạn chỉ cần đọc các phần tóm tắt này, rất tiện lợi cho những ai khó có thể đọc sách liên lục mỗi ngày mà vẫn nắm được mình đang đọc gì. Đây cũng là phần mình thích nhát trong bố cục trình bày của quyển sách."Sự tiến hóa của Vật lý" sẽ là một lựa chọn tuyệt vời cho những ai bắt đầu học vật lý để làm quen và tự định hướng tiến trình nghiên cứu Vật lý. Đó cũng là một lựa chọn không hề thừa thãi cho nhũng ai sắp tốt nghiệp chuyên ngành Vật lý để liên kết và sắp sếp lại hệ thống kiến thức đã học. Tôi đã ước mình đọc nó sớm hơn, song, không có gì là muộn khi ta muốn tự học những điều mới, tự phát triển chuyên môn của mình mỗi ngày cả. Vì chuyện học là chuyện cả đời và Vật lý thì chẳng có điểm kết thúc bao giờ cả.

    Einstein, through this book, unfolds the intricated lines of ideas that forged what is today's physics understanding. It gives a rather clear insight of why people put their faith and reason in some theories, and casted shadows of disapprovement on others. But the most interesting in my opinion is to learn more about the tipping points before each thought revolution. Those periods were highly tensed from the intellectual point of view. They reflect how difficult it can be for new and counterintuitive ideas to take root. This is directly related to how we, beings of subjectivity, construct our mental vision of the world and its laws. It is quite easy to take for granted a way of understanding any thing about and within the universe. Taking the step back from what we know, or believe to know, and take a hard look to determine the limits of our knowledge is one of the hardest and most important aspects of science.That is why I enjoyed reading this book.On another note, it doesn't include equations or technical concepts so it is a suitable reading for non professional scientists.

    مشاركة أينشتاين في تأليف الكتاب كافية لوحدها لجذب القاري للكتابالكتاب مختلف في طرحه للنظريات الفيزيائية فهو لا يسردها ككتب المناهج الدراسية بل يناقش الأفكار التي أوصلت العلماء لتبني هذه النظرياتكذلك يناقش المسلمات ويبين كيف تخلى عنها الفيزيائيون بعدما لم تستطيع الصمود أمام الأفكار الجديدةيعيب الكتاب ترجمة المصطلحات العلمية حيث استخدم المترجم مصطلحات لم أعهدها من قبل وكان من الأفضل لو ارفق المترجم المصطلح الإنجليزي بالعربي الذي استخدمه. الكتاب أحياناً يكون مشوق جداً وأحياناً تشعر بالملل وتارة يكون سهل الفهم وتارة أخرى يتعذر علي فهمه وبالمجمل فالكتاب أنيق ويستحق وقتك.

    La dimostrazione di come non sia necessario utilizzare un linguaggio complesso e autoreferenziale per esporre argomenti complessi, e di come basti poco per far comprendere a chiunque concetti fisici alla base della Scienza moderna. Fondamentale per chiunque sia interessato all'argomento, adatto sia ai profani che agli addetti ai lavori. Un'ottima lettura consigliatami da un altrettanto ottimo insegnante di Fisica del quale conservo uno splendido ricordo. Ce ne fossero di più di docenti universitari così...!

    Este é um livro realmente importante na física do século XX. Einstein explica claramente onde a relatividade se coloca diante do corpo de conhecimentos anteriores da física. Pessoalmente foi uma leitura marcante. Li pela primeira vez aos 15 anos e muitas vezes depois. Já dei o livro de presente para muitas pessoas. A clareza das explicações, a lógica, a simplicidade são o meu modelo de física bem contada.

    Me encanto, la forma de explicar conceptos un tanto complicados de una manera mas sencilla. Los ejemplos que se plasman son muy digeribles, y ahí creo, que se halla la magia de este libro. Recomendado para aquellos que, desean profundizar en temas de física, desde la mecánica clásica hasta la teoría de la relatividad, adentrándose un poco mas en en el dinámico mundo de la física cuántica.

    The path Einstein takes the reader down as he describes our world in ever more detail, starting with Galileo and Newton and ending with Bohr and Heisenberg, is an amazing journey eloquently relayed in plain understandable language.In my opinion, modern textbook authors could be much more effective if they followed his example.

    I once read a book of essays by Einstein and the writing was horrible to follow. I have heard similar stories about Einstein's book on relativity. The book, on the other hand, was a joy to read. No doubt this is due to Einstein's co-author.

    This is so far the most legible introduction/explanation of the development of physical theories I have read so far. The vocabulary is considerably simple and the illustrations are clear enough to make the basic concepts approachable for someone with no formal studies in the area like me. The book has no mathematical explanations, and Einstein says that in doing so he is sacrificing precision, and this is surely true, however the point of the book is not to present a precise understanding of physics concepts (and their corresponding mathematical formulas) but to present in simple form the different theories from mechanical physics to quantum physics, and how they relate to each other. Only the last then pages regarding quantum physics get a little blurry, mostly because he is presenting in hypothetical form aspects that, as far as I´ve read, have already been settled. He also states when introducing quantum physics that the statistical nature of the area has more to do with our lack of tools to understand it better (or more precisely) and not because there is an actual statistical nature to it. I don´t know if this is so, I´ve read somewhere else that this is an aspect where Einstein got it wrong, however I don’t think this makes his presentation of the subject lacking in any way.

    من الكتب القليلة التي تجمع بين البساطة والعمق , بالرغم من انه لم يضف لي معلومات كثيرة عن الفيزياء (ليس هذا الهدف من تأليفه اطلاقاً) فقد ساعدني على اكتساب فهم اكثر عمقاً للنظرية العلمية وعلاقتها بالواقع, وكيف يمكن ان يوجد اكثر من تفسير لظاهرة واحدة , وكيف رُفضت بعض النظريات ليس لسبب انها غير مطابقة للواقع او غير صحيحة وانما للصعوبات التي تواجهها او وجود تفسير ابسط واغنى (فالواقع كما يبين اينشتاين في الكتاب كساعة مغلقة لا نرى منها سوى الاميال تتحرك ونحن نحاول بجهدنا ان نفهم كيف ولماذا تتحرك), وجعلني ايضاً ان اهتم بتاريخ الافكارالعلمية وتاريخ العلم عموماً لانه يفتح ابواب مغلقة كانت امام العقل.ربما لو اضيفت المعادلات الرياضية وتمت مناقشتها لاصبح الامر اكثر متعتاً و أوفر فائدة, لان الفيزياء تبقى ناقصة بدون الرياضيات.

    A novice or a layman would marvel the book for its simplicity in the presentation of the complicated physical phenomenon. This book is definitely a masterpiece for a beginner who is learning physics. As Einstein himself followed the science of deduction so has he approaced the same in the presentation of the physical facts in this book. You will see a glimpse of it as you read through this book. The book would turn out to be not so gripping if you're already familiar with some of the physical facts. But I would defintely recommend this book to others.
