book blew my mind, even though I'm not on speaking terms with physics most of the time I understood everything and I am left a little speechless by some of the ideas explored here.
I think when we got to the wormholes I was already gone, Loved the writing style. Would recommend. When I started reading Asimov's book this week, written overyears ago, I figured I'd be the betterinformed, having absorbed current scientific knowledge in over a decade of technical education and more so for being a geek in general.
Turns out I was wrong,
Asimov writes about cosmic phenomena with heavy emphasis on basic concepts, without ever going over the head of the layman, while imparting new knowledge in almost every page.
I learned so many things about the Earth, planets, the solar system, and the Universe in general that I feel humbled.
None of this material should be new to a wellinformed denizen of thest century but, surprisingly, is.
This book is an absolute
gem for every person, whether amateur astronomer, geek or just the kind who likes to stare at the night sky and wonder about the sparkly bits.
On a sidenote, the first chapter talks about atomic and nuclear structure and forces and can seem a bit dry to start with.
Persist! It's worth it! Very first book I purchased, back in ', I think I wasA science geek in the making, . . It's been three decades since I first read this book, I decided to read it again after having just read sitelinkOrigins: Fourteen Billion Years of Cosmic Evolution by Neil deGrasse Tyson because it seemed that Asimov had told a similar story, but in the opposite order in terms of mass.
That is, the latter books starts with the universe and works its way down to planets, and Asimov's starts with the smallest objects, working its way progressively up to the most massive and the universe as a whole.
Asimov explains the difference between planets,, white dwarfs, neutron, black holes, etc, in such a clear and logical manner that it puts the whole range of states of matter in a context that even lay persons like myself can understand.
The differences in densities of the various celestial bodies alone is truly amazing, as is the eventual triumph of the weakest of the four forces, gravity, over the other three.
At the time of the Kolapsirajuća vasiona's publication Dark Matter and Dark Energy had yet to be proposed or confirmed, Inflation Theory had not been proposed, Black Holes were still theoretical, and Pluto was still one of the major planets with an estimated mass double that of Mercury andtimes its current estimate.
But still, even today with all that has been learned since the book was published, I feel it is still a worthwhile and enjoyable read for anyone wanting to understand the universe and our unique place in it.
I just wish we could have another Isaac Asimov in our time, to explain with such clarity and simplicity the advancetments of cosmology as he does in this book.
Marvellous! Прегледах “Гравитационната гибел на Вселената” с цел да си припомня някои факти относно Вселената, така че да ми е полесно за посложните четива на тази тематика, които по определени причини бях оставил на заден план.
Азимов, като един от найизвестните фантасти, е оставил дълбока следа върху тази книга, насочена към учениците от горен курс или просто любителите астрономи. Като начало стилът е много увлекателен Азимов все пак, описанията са пределно ясни и формулирани по изключително разбираем начин. С радост мога да отбележа, че уводните теми за физичните сили бяха почти дословно предадени на е една презентация за гравитационните вълни от фестивала на науката, което за мен е показателно за тяхната разбираемост, но и акуратност. Разбира се, тъй като е писана доста отдавна, част от информацията не е актуална или теориите са вече доказани или оборени, но фундаменталната и неотменима структура на вселената е описана особено подходящо за любители.
Като един от найголемите фантасти Азимов не пропуска да се впусне в кратки пътешествия отвъд доказаните теории и да разглежда от собствен поглед различните им интерпретации, което за мен беше любопитно и интригуващо. Общо взето това е едно увлекателно четиво за всеки, който се интересува от това, което се случва извън границите на нашата планета.
I've always loved black holes and I've always wanted to read Asimov, but I never realized how well the two would go together.
It's extremely approachable, for the content concerned, He writes a lot like Sagan in that even though astronomy requires a ton of math he simplifies it and mostly states it in comparative terms like ".
times the mass of the Sun" rather than ",kg".
The best part about this book, for me, wasn't even the black holes themselves it was everything else leading up to it.
I learned so much about the elemental forces, the formation of, and every different type of step of ending a star can have.
And what I love most it got down to the subatomic level and was still completely understandable.
The only thing that was a slight disappointment was that the book became less and less sure as it went on.
Really almost all of it was known fact until you got to the topic of black holes where it became much more of a "what if" game.
I can't blame Asimov, however, as he's just reporting the science and it was still entertaining and informative to read.
Maybe it's because it is a subject matter that interests me but I couldn't put this book down.
Asimov is on par with Sagan for making science fun but informative, Even though I'm sure there's been more discovered on the matter, I think this book makes a fine introduction to astronomy.
interesting read Тази малка книжка е препрочитам периодично , Азимов майсторски ни разкрива светът който ни заобикаля в галактиката. Черните дупки, вселената и нейният живот. I learned a lot about the universe from this book! Un magnifico saggio per chi volesse avvicinarsi a come una stella nasce e muore e lascia memoria fisica di se'.
. e non e' una metafora Most people know Isaac Asimov, for the work "I, ROBOT", My first contact with the author was during preadolescence through this book, And even with little knowledge of Physics at the time, I managed to understand how the Universe gears work.
Its four fundamental forces, the planetary formation, the birth of a star, the White Dwarfs, the Neutron Stars, the Pulsars and, of course, the Black Holes.
Isaac Asimov exposes in a simple way concepts that are very complicated, I learned a great deal about astro physics from this book! Well written and easy to understand, it's a very interesting book! This book is awesome and scary in the same time.
The scales, the predictions, the unknown they frightened me, I recommend it to everyone who wants to learn more about our universe, Was the mysteriousmegaton blast that flattened a Siberian forest inactually caused by a small black hole Does matter drawn into a black hole reappear out the 'other side' as antimatter, a sort of mirrorimage of the universe as we know it Could back holes explain the 'Big Bang' Does their existence raise the possibility that matter can move faster than the speed of light The noted scientist and science fiction author explores the exciting implications of black holes, taking the reader on an engaging tour from the atom's innermost core to the outermost reaches of the universe.
Interesting enough but it does drag in parts, This subjectively suffers in comparison, I think, simply because I recently read Davies' The Last Three Minutes, which covered much the same ground and was really enjoyable.
In general, I've read a handful of Asimov's science books now, and sometimes it does feel a bit repetitive.
I understand that in popular science you've got to start from the basics to ground your audience, but I feel like I've read something like the first chapter several times from him.
And he does delight in explaining exponents, but at least here that's confined to an appendix, A Physics book. This is basically a book explaining how the theory of black holes came to be, and the physical evidence in nature to back it up.
As of the writing of this book there had been no black holes discovered, and I did a quick Google search, and my initial impression is that they still have not found any. Update as of April, the first photo of a black hole has been published, Written in layman's terms. If the program of an Isaac Asimov's class was transcribed, it would be this book, Auf dem Stand von damals geniales Sachbuch, Lässig geschrieben, wenn das in Physik in der Schule vorgekommen wäre,
There is always the possibility that they are out there, just not where they can be detected from earth.
Heute kann das fast nur mehr Michio Kaku schreiben, dass man denkt, man kennt sich eh richtig gut aus, weils total lustig ist This book is blowing my mind.
Really interesting to read this book from years backabout black holes and supernova, It is amazing how far we have come in understanding, and yet how much also hasn't changed.
I grew up on Asimov and read nearly everything he wrote, so was fun to revisit his style.
However dn't use it as a reference!
Este libro consiste en ensayos que van guiando al lector hacia el conocimiento acerca de cuál es el ciclo de vida de una estrella.
El camino hacia el "Agujero Negro" comienza con una introducción que, en mi opinión, hace un muy buen trabajo de nivelar los conocimientos de distintos lectores hablando sobre densidades y los distintos tipos de fuerzas que se encuentran en nuestro universo junto con donde se encuentra cada una y cual es más fuerte.
Una vez pasado ese estadio, Asimov comienza a hablar sobre estrellas, descubrimientos notables y relaciona las masas con las fuerzas involucradas y su luminiscencia / color.
Y es ahora donde el libro se vuelve altamente científico, Los temas abarcados a partir de este momento se relacionan con los procesos que ocurren dentro de una estrella y que factores afectan su ciclo de vida.
Esta parte es sumamente interesante, pero a la vez se vuelve muy técnica, resultando en que por momentos se torne tediosa y hasta difícil de leer.
Pero no todo es malo, esta última sección entra en detalle sobre los últimos estadios de una estrella, partiendo desde su nacimiento y pasando por gigantes rojas, enanas blancas y terminando en supernovas, estrellas de neutrones o unos agujeros negros.
En verdad es un viaje increíble de la mano de Asimov, pero por partes se vuelve un poco pesado.
Si tenemos en cuenta que se trata de un libro de menos dehojas, la cantidad de información contenida en él es suficiente para dejar hasta el más ávido lector un poco aturdido.
