Robert L. Forward será recordado como uno de los autores más característicos de la ciencia ficción dura. Sus novelas de la saga de los Cheela, donde especula sobre las formas de vida que habitan una estrella de neutrones, han sido comparadas por su combinación de amenidad y rigor científico con Misión de gravedad de Hal Clement. Él mismo dijo de ellas: "Son un libro de tex...more

Recommends it for: Any lover of pure, excellent SF
Dragon's Egg has nothing to do with dragons -- the dragon's egg is a neutron star being visited by humans who are suspending themselves in a stationary orbit by means of a propulsion laser.

The laser light falls to and illuminates a small portion of the surface of the star. As it happens, the surface of the star has a "crust" of highly degenerate nuclear material, at densities and pressures that enable exotic nucleochemistry to occur -- nuclei with extended shape and structure that are "weakly" b...more
Once in a while, a novel appears that has everything unique to science fiction - a brilliant new idea, honest extrapolation of real science, a gripping story with fascinating alien characters, and the indefinable but essential sense of wonder. Not my words, an unattributed quote on the back on my paperback, but between that and Arthur C. Clarke's pull quote on the front, "Forward's book is a knockout. In science fiction there is only a handful of books that stretch the mind - and this is one of...more

Recommended to Jon by: Beyond Reality March 2011 SciFi Selection
This book is a fascinating, serious consideration of what life would be like on a neutron star. Given the gravity in such an environment turns everything into degenerate matter, molecules complex enough to support biology form by atomic nuclei sharing neutrons rather than electrons. Furthermore, the author postulates that in this high energy/density environment the creatures that have evolved here have a much higher rate of metabolism. One million times ours in fact - so that we get to see in ju...more

I don't read much Sci-fi, but my brother bought me this book for my birthday, so I gave it a go. Aside from the setting being on a distant star and the main characters being tiny alien creatures, this book is really a study about the evolution of a species and its society. I was rapt by the developments these beings made as they progressed through their ultra short lifespans, creating religions, laws, philosophies and superstitions. A fascinating read!
Humankind discovers a close neutron star where extreme gravity rules, and intelligent (small) life has developed. Since the star spins so fast, "time" on the star progresses faster for the lifeforms - about 15 human minutes are one of their generation. A large part of the book focuses on the developments on the planet, and how the Cheela develop from stone age-like warriors to space-travellers surpassing humans.

This is hard SF with a focus on physics, and by hard I mean hard to the point of unr...more
Alright, here's the basic gist: intelligent life lives on a planet that rotates five times per second. Because of the speed of rotation, gravity is very strong, and the life forms come out very unusual. Meanwhile, we Earthlings have discovered this asteroid, and send a research team to check it out.

The thing is, not only do these creatures live on a quickly spinning planet, they LIVE faster than we do. They think faster, age faster, and develop faster. For each Earthling 15 minute period, a gen...more
This is "hard" science fiction, my favorite kind.
The plot is driven by believable, yet imaginative, consequences of physical laws.
What's important to me in an SF novel is that things make sense.
I love it when I get the feeling that the story is how it has to be.
This book is a perfect example.
Astrophysics sets the scene, and the characters do the discovering along side the reader.
It's so much fun!
This book really blew me away. It is one of the most imaginative and amazing stories I have read. Furthermore, Forward is a scientist with JPL so his science in the story is right on. His follow up, Star Quake was also pretty good, but nothing he wrote after that did much for me.
This is a surprisingly good novel of hard science fiction. VERY hard science fiction. The author described it as "a textbook on neutron star physics disguised as a novel." That is, indeed, what it feels like sometimes. An important difference, however, is that large parts of the book are taken up in the adventures of the cheela (aliens) who mark important accomplishments along the path of the cheela into contact with humans. There are many long chapters dealing with battles between cheela clans,...more

I know I read it. But I can't remember the ending at all. I know the quests by the Cheela to find new homes got tedious. And the explanations of the science didn't make sense to me, which was frustrating because I do understand how science works and I do read science for fun. I'm guessing the date read. Does the fact that I don't remember it any better than that mean something, such as perhaps that it's not very good?

This was a fascinating piece of hard-SF, featuring some of the most scientifically exotic alien life I've encountered so far. It manages to lay out an engaging neutron star world, usually by showing rather than telling in a tour de force of world building. Even when it describes high physics, it doesn't fall prey to explaining theories as if in a textbook. And the science itself is a big part of the excitement!

It was a little slow to start (discovery of the neutron star), but I think the transit...more
This must be the geekiest sci-fi book ever. The author was probably beat up by the other geeks for lunch money. At times the book is filled with oceans of technical detail -- it reads like an engineering manual. There are even long appendices with complicated diagrams.

That being said, it is surely one of the most imaginative and greatest science fiction books.

The gimmick for the story is a race of intelligent creatures who live on the surface of a neutron star, and whose lives go by a million ti...more
I'm hard pressed to find a better example of hard SF that Dragon's Egg. I think I could actually feel my brain stretching to picture the world Robert L. Forward was describing. What kind of life could possibly live on the surface of a neutron star that rotates on the order of 10,000 revolutions per minute and with a gravity nearly a trillion times that of the Earth? How big would they be? How would they communicate? How would we know they're there? How could we possibly communicate and interact...more

Oh that was painful, but I finished it for my book club, and for science. And make no mistake: the science in this book is mind-bendingly excellent. Robert L. Forward's ideas (life on a neutron star, contact between cultures who exist at different time-scales, etc) are the kind of top-notch speculation that makes science fiction great.

But his writing is dreadful beyond belief.

I have never come across a writer in such desperate need of a co-author. Seriously, this book reads as if it were written...more

Recommends it for: If you don't mind science bludgeoned over your head
I think I have to justify my three stars for this story (I would give it 3 and 3/4 if I could). The fault lies in me, not the story, but I have to be honest about my opinion. As a hard sci-fi novel, Dragon's Egg has a lot of technical terminology regarding physics on and around a neutron star. Now, I was prepared for science in a hard sci-fi novel, but at times it reads like a long-winded thesis rather than a story, and that sort of killed the squidge of enjoyment that would have bumped it to fo...more
Es el primer libro que leo de ciencia-ficción dura (tras mi fallido intento de leer "Mundo Anillo" de Larry Niven) y tengo que decir que me ha quedado muy claro de que se trata esta "hard sci-fi". Pues creo que no me equivoco al afirmar que este libro, escrito por el "científico de fama mundial en el campo de la astronomía" Robert L. Forward, es uno de los mejores ejemplos de este subgénero.

Como tal, hay que reconocer que se trata de una obra muy elaborada a nivel científico. Los geeks interesad...more

While I am a fan of science fiction, hard SF usually leaves me wanting. Good science is great, but a good story is much more important to me than if the author got the principles of orbital mechanics correct. Thankfully this book has both. The book details the finding of intelligent life on a neutron star that is passing through our solar system.

It starts off a little bit slow for my taste, but once you are in the meat of the story, it moves a long at a good clip. It follows both the human astro...more

This is qualified as hard sci-fi, although being written in 1980, some of the science is slightly out of date, although not badly. In the not-too-distant future, researchers at Caltech discover a star closer to Earth than any other, located just below the constellation Draco, hence the name Drgon's Egg. It's a neutron star--a collapsed star that is very, very small (about 20km across) and dense and not very bright. A few generations later humans send out a manned spaceship to investigate it more...more
This is a story of evolution in a very unusual environment: a neutron star.

As some scientists on Earth detect a neutron star approaching the Solar System, an expedition is sent to study it at close range. Meanwhile life evolves at a fast rate, hours for humans being whole generations for the inhabitants of the fast-spinning star.

This is a very strange and interesting story. It begins at a slow pace, yet eons pass by as we see life emerging and evolving. Then as the human expedition comes near, t...more

Extraordinaria la ciencia, pésima la escritura. Todo el fundamento de como podría haber vida en una estrella de neutrones está genial. La evolución de la vida y la sociedad es totalmente tomada de la evolución cultural en la tierra, y está divertido leerlo, sobre todo que "mapea" 5 mil millones de años terrestres a unos 500 mil años de los "Cheela", que viven un millón de veces más "rápido" que nosotros. Lo que son tediosos son los diálogos inter e intra personajes, la poca profundidad psicológi...more
Really superb hard sci-fi. I became totally engrossed in the story of the cheela and their strange high-gravity home. The pace never lets up, with the author constantly exploring new implications of the environment and the impact of the human contact on society. If I had a criticism it might be that the cheela ultimately come across as humans in funny shaped bodies rather than a truly compellingly alien species - but this hardly detracts from the pleasure of the story.
Five stars, Dragon’s Egg by Robert Forward Dragon's Egg
is simple, straightforward, scientifically sound. Finally found and reread a replacement for the copy lent out long ago and never returned. Why is this story (and the sequel StarQuake Starquake) so much fun? A plucky researcher follows her hunch and discovers the neutron star passing near the Solar System. Mankind launches a mission (with the plucky researcher’s son as the mission commander) to study the star and discovers an intelligent rac...more

I found Dragon's Egg to be an enjoyable read. The concepts were definitely complex and the reader would be aided by some background in physics. It still is not too esoteric to detract from the story. One big discrepancy exists. It's my understanding that in the presence of a large gravitational body that time would slow down relatavisticaly speaking. Given this, it should be the Cheela not the humans who live out a slower life in relation to the other. I couldn't figure that the author who seems...more
I read this book probably 20 years ago (funny how I keep remembering books I read a long time ago as I try to catalog them all on Goodreads). I can't say I remember the plot in detail, but it was a really fascinating hard SF novel about intelligent life forms who live on the surface of a star. They were very alien but still believable -- Robert L. Forward did a great job of describing their environment and how the incredible heat and gravity affected them. Because of the gravitational effects, t...more

This book has absolutely nothing to do with actual dragons. Rather, it's about a race of slug-like creatures, the Cheela, who inhabit the crust of a dead neutron star and live at a much faster pace relative to Humans.

I don't read much hard science fiction, but I really enjoyed this book, even if some of the technical details went way over my head. The Cheela are probably the best aliens I've encountered since Alan Dean Foster's Thranx.

The omniscient, head-hopping narrative kind of bothered me at...more

It took me a while to get into it but once the story kicked off (a few chapters in), I was hooked. The scientific detail was wonderful - I had expected that; it was the fondness I felt for the protagonists that took me by surprise. It's difficult to get that balance right.
