The content was good and the explanations were very good but all this 'mini-me' stuff and sitting on a beach turns me off.

Même si ce voyage au long cours se déroule en pensée, nous sommes bluffés et restons bouche bée! En une fraction de seconde, nous transmigrons des espaces inter-galactiques au coeur des atomes ... Les poussières d'étoiles, les trous noirs, le mur de Planck, le déroutant et hallucinant monde quantique nous ''sidèrent'' ... L'humour facilite la digestion à l'instar ''des vases de Grand-Tante de Sidney''! Dans un élan de compassion, Christophe Galfard nous rappelle que nous sommes des ''CHNOPS''! Pour arpenter et infiltrer l'Univers dans ses multiples dimensions, l'auteur propose des scénarios pour le moins insolites. Ainsi, nous nous convertissons en pur esprit, nous nous réduisons '' en mini-vous passés en mode yogi'' ... Qui plus est, à l'aide du ''robot lanceur de balles'', nous pénétrons l'intimité des cordes ... Pour décrypter ces énigmes, plongez-vous dans ce livre! Un r é g a l ! Sa lecture ne nécessite aucune base scientifique préalable! Dynamisé par un esprit ludique, ce ''Road-book'' célèbre le Grand Mandala de l'Univers ... N'attribuer que ''5 étoiles'' à ce fascinant et astronomique ouvrage relève de l'infiniment petit! E = Mc2 (fil rouge de cette Odyssée) : élémentaire ... mon cher Albert ! --Par chamar3, le 1 août 2015 (Sur Rakuten.com) 5/5 I'm a bit uncertain on how to rate, or even review, this book. On the one hand, the explanations of physics, quantum mechanics, general relativity, astrophysics, cosmology, gravity, etc are pretty good and, most importantly, understandable without requiring a physics degree.* On the other hand, the imaginary adventurous travels (i.e. thought experiments) to such things as the inside of atoms and the cosmos in general just didn't really work for me, though I did eventually get used to it. Maybe this sort of thing works better for people who have pictures and movies pop up in their heads when they read books, but that simply isn't me. Otherwise, an interesting introductiory book that makes mind-bending subjects not so complicated, while managing to be entertaining at the same time. ~~~~ *Except String Theory. I think you need to have ingested a substantial quantity of magic mushrooms for that to make any sense. Using the magical power of imagination the author takes us on a rollicking tour of the cosmos, from the very large to the extremely small. Along the way, our narrator is subjected to a number of strange circumstances that confuse and befuddle his friends(and amuse us). We find out about the limit that we can see to because the universe wasn't transparent, we find out about quantum effects of things, and a number of other pieces of information all in a charming and enjoyable manner. The only equation to be found in this book is E=mc squared, which is an equation that a child can understand. So you don't need to brush up on your Quantum Field Theory equations or whatever, since that doesn't enter into this book at all. So this pretty much is what we currently know about theoretical physics in a really understandable package. It includes some other stuff too, like about things we can't possibly know. Since this edition was printed sometime in early 2016, it is also pretty current as far as I am writing this now. Theoretical physics, cosmology, quantum mechanics - they are all complex non-intuitive areas of science that are very difficult for the layman to grasp. There are any number of books attempting, with varying degrees of success, to explain these concepts to a wider non-technical audience. Galfard describes a number of very hard technical concepts and I learnt about how the universe works at both the largest and smallest scales imaginable. Unfortunately, like most technical authors in these fields, Galfard assumes that people without PhD's in theoretical physics will be terrified by this knowledge and must be prevented from either hurling themselves off a cliff in despair or reaching for the nearest pitchfork in angry confusion. The book is stuffed with strange stories about great aunts, beaches and ugly pottery that I suppose are meant to be comforting, or, perhaps worse, keeps telling us to calm down and take a deep breath like some patronising mindfulness procedure from a health and safety specialist. I do not doubt that Galfard and colleagues are very clever people, but they are not the only clever people around and may not even be the cleverest around. The area where Galfard fails is in explaining how we are so confident that this theoretical house of cards is the best description of the universe we have, where the gaps are, what the alternatives are (if any) and where the thinking is going next. geen besprekingen | voeg een bespreking toe

"Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, The Universe in Your Hand employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. To understand what happens to a dying star, we are asked to picture ourselves floating in space in front of it. To get acquainted with the quantum world, we are shrunk to the size of an atom and then taken on a journey. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations renders these astoundingly complex ideas in an immediate and visceral way." -- Geen bibliotheekbeschrijvingen gevonden. |
