    1. friends who know about physics told me that this book really does provide a comprehensible explanation of loop quantum gravity I was a little sceptical, having already seen a couple of unsuccessful attempts, but now that I ve read it I m convinced It does what it says on the box.If loop quantum gravity LQG hasn t been on your radar, let me give you some background and explain why this is a big deal Physics has for the last century rested on two basic theories, quantum mechanics and general relat [...]


    2. Before being technical, science is visionary Carol Rovelli, Reality is Not What it Seems 5 stars for poetry 3 stars for precision When one discusses matters celestial or theoretical or cosmological it best translates when done in math or poetry Rovelli has an amazing talent for singing the esoteric, theoretical language of Quantum Gravity He finds meter with its loops and rhyme in the paradoxes He is able to fluidly convert the edges of theoretical physics into a language that amateur scientists [...]


    3. Enlightenment la Rovelli serves 2 1 Divide the Dante into equal halves and fasten together with a good transdimensional adhesive to form a 3 sphere Be careful not to get any glue in the primum mobile Set aside to dry.2 Stir the Lucretius, Galileo, Newton, Einstein and Heisenberg until thoroughly mixed Add a little Anaximander to taste Put in a warm place until it has risen.3 Add the Feynman path integral and the lattice approximation to the spacetime Whisk into a spin foam using a quantised volu [...]


    4. Making SpaceQuantum Gravity is the closest thing in Physics to a coherent explanation of the origin and fate of the universe how it began, how it works, how it evolves Quantum Gravity also has a pretty fair shot to reconcile the apparent paradoxes and contradictions involved in and between the theories of General Relativity and Quantum Mechanics Most recent scientific observations favour it over alternative theories as the way forward for Physics But Quantum Gravity does fail to explain one impo [...]


    5. I ve always thought that the generally accepted solution to Zeno s Paradox wasn t very acceptable A curve approaching infinitely small zero But really, they aren t equal You just kind ofund down So imagine to my surprise, Rovelli supplies the most satisfying solution ever Spacehold onI have to pause dramatically, because this is just mindblowingSpace is granular That s right Space itself is chunked just like light is made of photons HOLY SHIT That is why the hare can pass the turtle There is no [...]


    6. This is an introductory book to one of the most promising theories of quantum gravity currently attempting to merge quantum mechanics and general relativity Loop Quantum Gravity LQG , of which the author is one of the co founders Loop quantum gravity posits that spacetime is essentially just a new field, conceptually not dissimilar to the other quantized fields postulated by Quantum Field Theory, and similarly characterized by features such as granularity, probabilistic behaviour and indetermina [...]

    8. Does anyone know what spinfoam is in French I was trying to describe this book to a francophone friend and couldn t find a translation The word comes across as sensible in English, but cume de spin sounded just plain weird to both of us My friend was visibly unimpressed when I told her that that what the world was made of.


    9. I was no great fan of Carlo Rovelli s flowery, overpriced previous title, and the introduction to this book on loop quantum gravity has a similar style, but thankfully it settles down a little However, there is still rather too much of the woffle, reverting to floral form on Lucretius and his atomist poem on nature For those who remember How to be Topp, this is the Fotherington Thomas school of popular science all Hullo clouds, hullo sky We then get onto Galileo At times, Rovelli s history of sc [...]


    10. Given the audacity of several titles on string theory that have been published for the last decade or so, I can forgive the overly grandiose title here A appropriate title would be, The Contextual Justification for Early Elements of the Theory of Loop Quantum Gravity as a Means of Linking Quantum Mechanics and General Relativity If this is your first introduction to several modern concepts in physics then this is a 5 star book for you, those familiar with the material can likely skip the entir [...]


    11. I finished it, for which I deserve five stars The author used great illustrations, for which he deserves five stars.However, I think the author should have described certain quantum ideas, like spin networks and loops with illustrations and longer chapters and words rooted in common everyday language but on the other hand, my brain grasps liberal arts with ease while I flounder and drown in math conceptualizations, not to mention in solving higher math equations Maybe the author DID describe a [...]


    12. This book is a modern day, On the Nature of Things Like Lucretius himself, Rovelli is a poet who, with his words, constructs beautiful images of the true nature of reality The key message in this book is that everything comes down to geometry and the geometry of space is much interesting than we probably suppose Energy has morphed into various shapes as it traveled from the radiation of the hot, dense, atom sized ball it was when it was young, to elements and forms seen in the cooler, expanding [...]


    13. Questa fisica Questa divulgazione Questa chiarezza Rovelli sa di cosa parla e sa parlare, capace di riassumere la fisica dalla Grecia a oggi Come vorrei fosse il mio insegnante.


    14. Rovelli defende uma outra interpreta o da gravidade qu ntica que eu n o conhecia, a Loop Theory Em oposi o s supercordas adotadas e explicadas pelo Sean Carroll em The Big Picture On the Origins of Life, Meaning, and the Universe Itself Ele faz um timo trabalho de chegar nesse ponto explicando o conceito de gravidade atrav s da hist ria, dando alguns insights que n o tinha visto em outros livros Mas n o fica t o claro o que conclus o cient fica e o que especula o ou extrapola o sem suporte o mes [...]


    15. This is amazing Complicated concepts put into simple, everyday language that makes them easily understood I can t get over the fact that so many of the early scientists figured stuff out simply by changing their own perspective Roy McMillian is a genius on the audio I can t rave enough about his narration.


    16. Carlo Rovelli, a prominent theoretical physicist, presents to the broad public an easily accessible introduction to quantum gravity The book traces the development of ideas from antiquity, through the renaissance, to present times It s a story about the origins and development of special and general relativity, quantum theory, and their long awaited reconciliation quantum gravity We get a glimpse into the process of inventing a scientific theory, specifically, the natural progression to loop qua [...]


    17. Although the subject the journey from the Newtonian laws of motion to quantum physics is fascinating, Rovelli s book is a not very succesful mix of very basic information which is boring if you are the least bit familiar with the topic and not very well explained difficult details and examples which are incomprehensible if you are new to the topic.

    19. The first half of this journey to quantum gravity provides a lively and poetic insight into the key moments in the history of development of atomistic theory, from Leucippus, Democritus and the Lucrecius s poem On the Nature of Things, through Newton, Faraday and Maxwell, to general relativity and quantum theory.The second half is an enthusiastic and entertaining attempt to explain to the general reader the implications of the ongoing theory known as loop quantum gravity.This part was an extreme [...]


    20. If you have a philosophical bent and like classical antiquity and Western civilization history then this physics book might be just the thing I enjoyed it greatly mainly for those reasons Rovelli places modern physics and cosmology into a western philosophical story It, of course, is bigger than any one culture but it is a tradition I have grown in so it appeals to me Rovelli combines recent physics and Ionian Presocratics Democritus and the quantum, Dante, and Einstein, Newton, Archimedes, and [...]


    21. This book is split into two parts The first describes relativity and quantum theory The second part tries to explain where physics is going now the Big Bounce, covariant loops,thermal time, spinfoam All brand new concepts to me and not sure I managed to get my brain around them all Certainly an interesting and mind expanding read.



    22. I had come across references to Carlo Rovelli previously, probably in the books I read by Lee Smolin, so when I saw this come into the library I was interested in checking it out Rovelli is a leader in research into the Loop Quantum Gravity approach to fundamental physics, and this book describes that perspective in fairly simple non mathematical terms, rather than in depth The book is aimed at the layperson with little knowledge of physics, so it takes the historical approach starting with Demo [...]


    23. 39th book for 2017 A relatively quick read on modern physics starting with the Ancient Greeks and ending with Quantum Gravity I have mixed feelings about the book Rovelli s prose is quite poetic at times and perhaps a little damaged in translation from the Italian I found the historical background quite clear, but when he got to describing quantum gravity, and how space time do not exist at the most basic level I was lost That s a shame, because it s the most interesting part of the book It woul [...]


    24. It s hard to review a book like this Suffice to say the information was dizzying yet compelling, and if I had the mathematical ability, I d jump head first into theoretical physics, because it aims to reveal the very nature of reality, which to me, is fascinating than anything else.


    25. TOO WORDY holy crap Get to the point It s nearly poetry Which is probably lovely, but I was hoping to learn something Oh boy.


    26. Avendo, da sempre, un rapporto ostico ed altalenante con la matematica, posso solo esprimere una opinione sul contenuto filosofico di questo titolo, che credo si concentri tutto nel tredicesimo ed ultimo capitolo accettare il fatto di non sapere, spingersi oltre i propri limiti, continuare a cercare risposte a domande sempre pi apparentemente infinite per colore che impostano la propria vita su questi principi, l unica via, il solo modo di scoprire realmente chi siamo e dove viviamo, senza farci [...]


    27. I am a lawyer and most certainly a scientific layman, but I am determined to remain an informed fan of science and this is definitely not my first science book Relativity I can fathom, or less, quantum physics I am familiar with up to a certain degree, I don t know the Standard Model intimately but at least I recognize what people are talking about when they use the name, string theory I could never really follow but occasionally I keep trying, I am mostly fine with cosmology It is, however, my [...]


    28. If you ve ever wondered about the nature of reality, what is the fabric of space, and how does time work, then this book is for you I thoroughly enjoyed this introduction to the theory behind loop quantum gravity I thought the author, Carlo Rovelli, did an excellent job of illustrating some complex theoretical physics in a manner that is easy for anybody to understand, whether you are a physics pro or you have very little background in or aptitude for physics To do this feat, Rovelli started way [...]


    29. Ottimo resoconto storico e scientifico, per cui emergono con grande chiarezza dei concetti centrali che, pure essendo astratti, sono indispensabili per capire a quale punto ci troviamo nella cultura umana Si aggiunge ad altri recenti libri tanto accessibili a non specialisti, quanto ad alto livello quelli di Sean Carroll, per un solo esempio.A mio parere, piu presto che La realta si trovera in traduzione inglese e in altri idiomi, meglio sara per la crescita della nostra condivisa maturita cultu [...]
