    About "Richard Feynman Roger Penrose"

      • Richard Feynman Roger Penrose

        Richard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics he proposed the parton model For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin Itiro Tomonaga Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster In addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology creation of devices at the molecular scale He held the Richard Chace Tolman professorship in theoretical physics at Caltech See


    1. Let me start with a one-sentence summary: this is a thoroughly enjoyable little book explaining, in a beautifully intuitive and holistic way, the main core features of Einstein's relativity, without getting bogged down into too much mathematical detail. The target audience of this book is the interested layman with high school mathematics knowledge and a passion for physics: it falls into the particularly tricky (from a pedagogical standpoint) grey territory between popular science and real scie [...]

    2. All of our ideas in physics require a certain amount of common sense in their application; they are not purely mathematical or abstract ideas.It is difficult to review these books, as their titles are so descriptive. This book, as well as its companion, Six Easy Pieces, is a book that can judged by its cover. But this is a book reviewing site, after all, so review them I must.As you probably know, this book, like its predecessor, consists of excerpts from Feynman’s legendary Caltech lectures. [...]

    3. Learn Relativity from the maestro Richard Feynman himselfIn the introduction to this book, Roger Penrose, another great theoretical physicist of our times, states that "Relativity is not airy-fairy philosophy, nor is space-time mere mathematical formalism. It is a foundational ingredient of the very universe in which we live." On that note, it is encouraging for many readers that this book offers a great opportunity to take that extra step to learn the mathematical constructions for the effects [...]

    4. Kendisi de ünlü bir fizikçi olan Feynman tarafından kaleme alınmış bu kitap, Einstein'ın Görelilik Kuramı'nı ve onunla ilişkilendirilebilecek diğer kavramları anlaşılır kılmayı amaçlıyor. Kütleçekim, uzayzaman, yüksek hızlarda hareket gibi kavramlar pek çok açıdan insan algısının sınırlarını zorlayan türde şeyler. Bu durum fiziğe mesafeli olanlar kadar, ortalama fizik bilgisine sahip olanlar açısından da böyle. Kolaydan zora doğru sıralanmış 6 bölü [...]

    5. Pretty aptly titled book. In contrast to "Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher", there was a lot more mathematical formalism that was a little tough to follow, but with patience could be understood. The six lectures are put together so you can better understand Einsteins' special and general relativity. The book really made me appreciate the power of mathematics and interpretation to determine the nature of the real world. I actually found out how they d [...]

    6. Whew! This one was not-so-easy. My Algebra, Trigonometry, and Vector Analysis skills are very rusty. However, that being said the ONLY way to see the ultimate beauty of Einstein's theories is to "do the math."Feynman is awesome.

    7. For all of those who took introductory college level physics courses once upon a time, and wish to know more about the development of the science during the 20th century, this is a very authentic introduction. A basic understanding of calculus is important, even if it was acquired some years ago and partially forgotten, to comprehend the various mathematical explanations that go along with any serious study of physics. If that doesn't scare you, or if you have the will and the patience to give i [...]

    8. "Not so easy" is right! Feynman designed these lectures so that, he hoped, physics non-majors would be able to grasp the concepts, while majors would get a sense of the excitement of physics and maintain their interest.There is a lot of math in the book, but one can ignore most of it (as I did), and try to understand the ideas from Feynman's very clear and simple language. But, simple as Feynman's language is, these concepts are hard for even a smart person to get his or her head around. We have [...]

    9. Essential reading for relativity enthusiasts (of the weekend variety, I might add- the more academic ones might be better served by lectures given by the wild-haired maestro himself). Requires, and assumes, knowledge of Std XII Maths and Physics- you'll be pretty lost if you don't know what the hell differentials and integrals are. Though written in Feynman's casual, conversational style, the book never fails to make your head spin, and it's fun to put the book down on your chest in the middle o [...]

    10. I learned that there are somethings I cannot grasp and sometimes these things are not understandable by most people. I am one of them when it comes to this book. However, the main thing is that I learned that this man was unique in that he was brilliant and could teach also. A most commendable combination in any person he had a sense of humour! I honor the man even though I did not understand most of the book.

    11. Richard Feynman was a brilliant, creative teacher. In this volume he tackles some of the trickier subjects in physics. He starts slowly, even simplistically with a discussion of symmetry and builds one upon the other taking the reader through some relativistic topics and finally concluding with a fantastic description of space-time geometry. In a few short lessons, he showed me what had taken months at university to understand. I wish there were more teachers like him today.

    12. Very appropriate title, especially if one has not read complete lecture series. One more book that needs to re-read.Classic Feynman otherwise.

    13. "Suhteellisen helppoa - seitsemän lukua fysiikkaa" on suomennos luennoista, jotka laadittiin teoreettisen fysiikan professorin ja nobelistin Richard Feynmanin California Institute of Technologyssa vuosina 1961-1963 pitämästä maailmankuulusta fysiikan alkeiskurssista. Vaikka kurssista on tullut fysiikan klassikko, niin omasta mielestään Feynman ei onnistunut opetuksessaan erityisen hyvin. Kun hänelle huomautettiin, että sentään noin 20 oppilasta kurssin 180 oppilaasta oli ymmärtänyt m [...]

    14. This is a very entertaining book by an amazing teacher. As a Physics student, reading this book gave me a great advantage while taking courses on modern Physics. The book is a series of lectures intended for second-year Physics students at Caltech, so do not despair if you cannot grasp every single idea in the book. I highly recommend reading it after reading Six Easy Pieces.

    15. Really accessible book. Similar to QED in terms of level of physics knowledge needed. He did really well with writing for the average lay person. It also has some unique thought experiments for developing an intuition regarding relativity. I especially like the ant on the reverse hot-plate analogy.

    16. It was both a challenging and exciting read, as I have zero background in Physics. Feynman does a great job of presenting the material in a digestible manner. I found the 'Symmetry in Physical Laws' & 'Relativistic Energy and Momentum' chapters most fascinating. I'm currently ordering the book that precedes this, 'Six Easy Pieces', which I probably should have read first but was unaware of until I just flipped to the back of this book and saw the advert. Oops!

    17. Richard Feynman was a brilliant scientist. While there are many brilliant scientists, perhaps the term gets thrown around a bit too loosely. Feynman was an elite scientist, maybe one of the most influential and important in American history. What truly sets him apart, more than this, is he is also one of the best teachers. He has the ability to use thought experiments to explain complicated concepts, and in this book, he tries to explain some of the most difficult. Vectors, Physical Symmetry, th [...]

    18. Feynman, Richard P. SIX NOT-SO-EASY PIECES. (1997). ***. I don’t want to scare anyone off with my so-so rating of three stars. If you are in a university now, majoring in one of the hard sciences, or if you are a practising physicist, you will love this book. For me – having been out of it now for a few years – it brought back painful memories of how hard I had to work to get through some of my courses, and never really understood much of what I was supposed to have learned. The first (of [...]

    19. Yes, well, I have to come clean. This is really way beyond me, especially the maths itself, although I love the conceptual side of maths and the understanding I can tell myself I've gained when I read explanations by mathematicians etc whose words seem to give insight. And Feynman's words are not even written words, really, but fun-filled attempts to give the beginnings of understanding to whatever audience he might be addressing. I wanted to read this because I loved his Six Easy Pieces, which [...]

    20. Ah yes, the six not-so-easy pieces. Another winner!This book is more "hard science" than it's predecessor. Meaning that there is more math and mental effort required to follow along. But not a lot, as the bulk of the discussion is still textual. One can skip over the vector math sections and still get the "gist" of the topic: relativity. Thus, enjoying the way Feynman approaches and details how we see "our world" versus those stuck in a two dimensional one.The book is a treat (as are the other b [...]

    21. Feynman olağanüstü etkili bir eğitimciydi. Sayısız ödülleri arasında, 1972'de kazandığı Örsted Öğretim Madalyası'yla özellikle gurur duyardı. Özgün olarak 1963'te basılmış olan Feynman'ın Fizik Dersleri'ni, Scientific American dergisinde bir eleştirmen şöyle betimliyordu: “Çetin, ama besleyici ve leziz. 25 yıl sonra öğretmenler için yol gösterici ve yeni başlayan öğrenciler içinse en iyisi.” Bu kitabın içeriğini oluşturan konular Feynman’ın fizik d [...]

    22. I've read this book right after I finished the first part, "Six Easy Pieces" and the differences between the books are vast. In the first book, you are just a person from a crowd whom Feynman educates on basic workings of the universe. The Not-so-easy Pieces makes you feel more of a student at a lecture, occasionally scratching your head and wondering if your math skills are good enough to fully understand the material. There is definitely quite a few of equations in this book, which is contrast [...]

    23. Six Not So Easy Pieces es un extracto de algunas de las lectures de The Feynman Lectures on Physics publicadas por Caltech, estas 6 en especifico tratan sobre la relatividad general, el espacio-tiempo y la simetría dentro de las leyes naturales. Feynman siempre pensó que la mayor prueba de conocimiento en algún tema es el poder explicarlo de la forma más sencilla, objetivo que este extracto consigue con facilidad. El libro es una gran lectura para todos los interesados en conocer un poco má [...]

    24. Whereas Six Easy Pieces was a well-written physics primer for lay readers, Six Not-So-Easy Pieces reads like a poorly conceived text book. The introduction of vectors serves to form a foundation for the explanations which follow in the next chapters, but lay readers who don't already have an exposure to vectors aren't likely to learn them from this brief passage, and more experienced readers already have an in depth knowledge of the subject. This second volume loses or neglects everything which [...]

    25. I have found this book much more interesting than the first part. In the first part I discovered that Feynman, as a popularizer of science, is not so good as it is said (in my opinion, of course). With that in mind, I was expecting a difficult read here and I've found it. However, this book contains a very good and complete description of many issues related to Einstein's relativity and other pluses, like an amazing chapter on symmetries. I still think that the easiest introduction to Einstein's [...]

    26. I highly recommend this book to whoever is interested in Einstein's theories of special and general relativity. The book dives a little bit into the math of the theories but delivers the ideas very clearly through Feynman's well known talent of giving appropriate analogies for any topic. Some bits of this book are hard to grasp, especially in the idea of symmetry of physical laws as well as the math of the curved space. I think these two topic are a bit difficult to understand through reading th [...]

    27. I've only ever read one lucid explanation of relativity, and that was a chapter of Music of the Spheres. But Richard Feynman is a great teacher, and this is a lucid book with actual equations. I could wrap my head around this subject under his guidance. I wonder if there is a seminal textbook on the subject
