    1. Steven Weinberg born May 3, 1933 is an American theoretical physicist and Nobel laureate in Physics for his contributions with Abdus Salam and Sheldon Glashow to the unification of the weak force and electromagnetic interaction between elementary particles.He holds the Josey Regental Chair in Science at the University of Texas at Austin, where he is a member of the Physics and Astronomy Departments His research on elementary particles and physical cosmology has been honored with numerous prizes and awards, including in 1979 the Nobel Prize in Physics and in 1991 the National Medal of Science In 2004 he received the Benjamin Franklin Medal of the American Philosophical Society, with a citation that said he is considered by many to be the preeminent theoretical physicist alive in the world today He has been elected to the US National Academy of Sciences and Britain s Royal Society, as well as to the American Philosophical Society and the American Academy of Arts and Sciences.Weinberg s articles on various subjects occasionally appear in The New York Review of Books and other periodicals He has served as consultant at the U S Arms Control and Disarmament Agency, President of the Philosophical Society of Texas, and member of the Board of Editors of Daedalus magazine, the Council of Scholars of the Library of Congress, the JASON group of defense consultants, and many other boards and committees.

    2. Probably just a lucky hit? It's getting harder and harder to tell with these new deep learning architectures. Though if a human being had done that, I'd have said it was quite insightful._______________________[After reading]- Professor Weinberg, thank you for agreeing to testify in front of the committee.- The pleasure is all mine, Senator.- Very good. Now, let's get down to business. Why should the US pay 8 billion dollars to build this - ah -- Superconducting Super Collider.- Thank you. You k [...]

    3. Incredibly lucid, honest and concise. Possibly the best popular science book I've read so far. But I do have to warn you that I'm a theoretical physicist with worldviews closely resembling those of Weinberg, so don't expect an unbiased review.Although he doesn't go too far to explain the actual laws of nature, as one might expect to see in a popular science book, Weinberg touches on some of the most important questions. Can we have a final theory? Are we close? How can we know if we are close? I [...]

    4. Absolutely a must read. I cannot believe it took me this long to read it. Weinberg presented his and other physicists' theories that try to explain the universe. As difficult and possibly impossible as this goal may be, Weinberg makes it fairly simple for the curious reader. He really does have a gift for relaying complex knowledge to the non physicist. Since this book was written in 1992, I think readers can and should forgive it for its focus on beauty as criterion for a viable theory. It is o [...]

    5. I'm again about half way through this one, but I've spent the last couple of days thinking about a quote in this by Bohr. Now, you need to know that the Uncertainty Principle states that one can not know both the position and the momentum (sometimes people say velocity – but it is actually momentum, as they wrongly assume that a particle’s mass won’t change) of a particle at the same time and that the more accuracy you have in measuring the one, the less you have of the other. These types [...]

    6. This is sort of an intellectual biography of Weinberg’s career in (quantum) physics, and a pitch for the Superconducting Super Collider that was under consideration in the early 1990s. As with many other books for “general readership” in physics, a good part of this book is difficult to understand. Even so, there are several things that stood out.Weinberg states outright that quantum mechanics, in contrast to classical mechanics, describes nature in terms of waves and probabilities, not pa [...]

    7. I won't judge this book on its out-of-dateness or it's terrible audiobook narrator (not the author's fault), and I will try not to give too much weight to the ending of the book, where Steven Weinberg leaves the realm of science and instead moves into religion (this is never a good thing for a scientist to do - too often they conflate "science being unable to prove the existence of God" with "science proves God doesn't exist"). The rest of the book is pretty good, though not exceptional, and not [...]

    8. ليس تقيمي الاخير والنهائي لهذا الكتاب، سأعيد قرائته مرة اخرى بعد ان اتعمق اكثر في فيزياء الكم لان الكاتب طرح الكثير من المفاهيم والمسائل الفيزيائية التي وجدت صعوبة كبيرة في فهمها

    9. يجادل ستيفن واينبرغ في السبل التى ستمكن الفيزيائيين من الوصول للنظرية الشاملة, مبتدئا بالاختزالية في العلوم وجدواها والانتقادات الموجهه اليها ويحسب نفسه من انصارها واشد المتحمسين لها , ويعرج بعد ذلك على الرؤية التاريخية في العلوم والدور الغائب لها في التصورات الاخيرة وفي [...]

    10. Steven Weinberg is a remarkable man. A particle physicist and cosmologist, and Noble prize winner (due to his work on the electroweak theory), he is also passionately interested in the history of science and a popularizer of the work he's involved in.In The First Three Minutes (1977) Weinberg tried to explain to the popular audience the current scientific insights about the origin of our universe. This was (to my knowledge) the first accessibe and complete account of this topic.Ever since the 70 [...]

    11. At last, respite! Finally there comes a writer who does not evoke God when writing a book on physics for general public, finally I get to read someone who brings out his point with little or no historical bullshit or brings in no orientalism or mysticism when dealing with the interference pattern!! Maybe if I were a reputed critic working for Times in 1993, I might have started my critique in the above manner for Steven Weinberg’s ‘dreams of a final theory’.Well, I my short, stupid life I [...]

    12. Steven Weinberg is one of twentieth century's greatest theoretical physicists. He is one of the codiscoverers of the Electroweak Theory, an important piece of the puzzle that describes all of the fundamental forces of nature. He is also a very prolific writer, with several important textbooks and a few books that aim to popularize Physics and make it accessible to the general audience. The theme of this book is the long standing problem in Physics, and that is the one of unification of all force [...]

    13. Fascinating mashup of sciences and arts usually thought to be exclusive of the others, but this book demonstrates, probably more clearly than any other I've read, that physics, mathematics, philosophy and religion are inextricably intertwined. There's something here to stimulate the fundamentalist physicist, the atheist mathematician, and any and all combinations in between.

    14. El libro puede tener un argumento interesante, especialmente si la persona es interesada sobre el tema científico. Cetamente no es el más reciente, pero sigue siendo curioso por qué rico en su conjunto: el argumento se centra en la investigación. Dibuja que detrás del escenario se tiene una teoría sobre todo. Por lo tanto el libro es basado esencialmente en las leyes de la física ya que son las reglas básicas capaces de demostrar las cosas a la conciencia humana.La escritura fue casi seg [...]

    15. Weinberg manages to include a lot in this book, although it's of a very manageable length. It's primarily about particle physics of course, but there is also plenty of history of science, cosmology, and a few funny anecdotes. The discussion about reduction is perhaps the most interesting though, and also the reason why I picked up the book in the first place. Weinberg is skilful in explaining difficult material understandably -- the discussion of symmetry principles comes to mind. It must be sai [...]

    16. from a giant of physics, a living legend expected, this book scales great heights of contemplation, blah blah but I'm mostly here for the upfront potshots he takes at the 'unreasonable ineffectiveness of philosophy"."" After a few years' infatuation with philosophy as an undergraduate I became disenchanted. The insights of the philosophers I studied seemed murky and inconsequential compared with the dazzling successes of physics and mathematics. From time to time since then I have tried to read [...]

    17. Il libro può avere un racconto anche interessante, specie se interessati a l'argomento trattato. Si concentra sulla ricerca, e trae uno sfondo che su tutto si ha una teoria, quindi basato essenzialmente sulle leggi della fisica in quanto sono le regole fondamentali capaci di dimostrare le cose alla coscienza umana. La stesura quasi certamente fu scritta con diversi libri di testo importanti, altri concentrati soltanto sul diffondere la fisica: la descrizione del fisico Weinberg mostra vari aspe [...]

    18. Great book. Gives a detailed history of atomic theories, and a great review of current theories. May be written at a level that many people would find challenging. But still accessible to science enthusiasts

    19. Originally published on my blog here in October 1998.Steven Weinberg, winner of the Nobel prize in physics for his work on elementary particle theory, wrote this book while involved in the campaign by American physicists to obtain a grant for the Superconducting Super-Collider (SSC). This campaign colours the book, a lot of it being Weiberg's responses to the type of questions both physicists and non-physicists asked about the project and its aims, or an outcome of his own background thought as [...]

    20. Particle physicist Weinberg's extraordinary intelligence infuses every sentence, but without pushiness or arrogance. Not every concept and theory he presents comes through clearly to this non-mathematical layman, but the currents, both of writing and thought, flow smoothly. And he brings a different approach to some concepts than I have run across in other "popularizations." (Weinberg includes no math here, but certain ideas in particle physics are close to impossible to envision completely with [...]

    21. Wow, this one took me a while. It may be because my students are taking the AP exam this coming Monday, but it is more truthfully because this book was dense. Very good, but dense. Originally published prior to the defunding of the SSC in 1994, Weinberg used his discussion of the final theory as a means of framing his well-considered defense of this amazing piece of technology. The afterward, "The Super Collider: One Year Later" read like an open letter to Congress, and was clearly sorrowful, bu [...]

    22. Steven Weinberg is a prolific and significant figure-head of the late 20th century physics community. So, I was a bit intimidated by the potential complexity of this book. Quickly mulling over the pages did not reveal any math text; which came to a big surprise for me. It looked like it was going to be another qualitative overview on a specific branch of physics.It turned out to be quite welcoming and specifically catered towards the layman. I definitely appreciated his take on the state of scie [...]

    23. In the preface, Kuhn briefly, indirectly but beautifully thanks a friend and colleague of his, Stanley Cavell, a philosopher who, while focusing on ethics and aesthetics, was one of the few people with whom Kuhn was "…ever been able to explore my ideas in incomplete sentences."It is a truly profound gift to find such people, and as I read this essay, I was hit by the onrushing awareness that Kuhn was one of the thinkers with whom, in many respects, I was staggeringly precisely on the same page [...]

    24. Readability 5. Rating 7. Subtitled “The Search for the Fundamental Laws of Nature”. Weinberg discusses the advances made in this search over time, the difficulties and obstacles, the advancements and the launching points for the future. He writes well and with a very human touch, but much of what he discusses simply goes over my head. I get about as far as a general description of the topic, then I tend to lose touch with the details. Nevertheless, it was a worthwhile foray. He does an excel [...]

    25. He descubierto que soy positivista (y yo sin saberlo) porque creo que hay principios más fundamentales que otrosn embargo estoy de acuerdo en que: "toda explicación puede ser a su vez explicada a partir de una teoría o conjetura de un grado de universalidad mayor. No puede haber una explicación que no necesite una explicación posterior"(K. Popper)Así que no estoy muy convencido sobre eso de la teoría finalOtra cosa, que siempre me ha parecido sorprendente y parece que a Weimberg también: [...]

    26. Uh-Oh, author readingLater - although it is a nasal rendition, the interesting subject matter means one can click off from the vocal idiosyncrasies to a greater extent.A theory of everything (TOE) is a putative theory of theoretical physics that fully explains and links together all known physical phenomena, and predicts the outcome of any experiment that could be carried out in principle and is not related to math in anyway.There is allegedly a sadness in physics that comes from thinking that s [...]

    27. I read this several years ago. An interesting book that focuses on the quest for the so-called 'theory of everything.' Weinberg believes (or at least did when this book was written) that the laws of physics will eventually be able to explain human consciousness. I recently watched a television special based on Hawking's newest book, The Grand Design, and he states the same. It may well be trued they spend one episode (there are several episodes based on the book) discussing the implications of t [...]
