It causes riots and religions. It has people dancing in the streets and leaping off skyscrapers. And it's all because of the impenetrable gray shield that slid into place around the solar system on the night of November 15, 2034.

Some see the bubble as the revenge of an insane God. Some see it as justice. Some even see it as protection. But one thing is for certain -- now t

Al terminar este libro ha quedado en mí una sensación como de redondez al resolver la cuestión, como de acierto total al intentar novelar la física cuántica (reconozco que hay que tener ciertas nociones de cómo se comporta el mundo microscópico para disfrutar plenamente de este libro).
Sensaciones personales aparte, Egan siempre es un generador de conceptos e ideas muy novedosas y estimulantes (el libro lleva publicado 22 años sólo), transmisión de datos a través de la piel, implantes neuronales

I'm not a huge Greg Egan fan. But that may well be because he outgrew me, and I stopped keeping up with the right varieties of science to really appreciate his work. However, Quarantine, one of his first novels, is one of my favorites. I reread it over the past few days, but I first read it when it came out. We older SF fans talk a lot about the sense of wonder (aka sensawonda). But over the years, I got less and less of that sense from the physics/chemistry parts of SF and more from things like ...more

4 Stars

I am giving the overall of this book 4 stars only because Egan is not afraid to write hard science fiction. This is my second Egan novel that I have read, Clockwork Rocket (a book that I loved) being the first. Greg Egan is not afraid to use fiction to explore real science, physics, quantum mechanics, and deep philosophy.

This book Quarantine, a first in a trilogy is focused around quantum mechanics, specifically around a measurement known as Schroedinger’s Cat. “Quantum mechanics descri

If you really like quantum mechanics and philosophizing on all of the strange reality that it entails, then you'll love this book. Otherwise, it's basically a mind f---. The ideas explored here aren't novel, but they are taken to such an extreme that it's hard to enjoy the book as a story instead of a thought experiment. And a challenging one at that - even with quite a bit of qm theory under my belt, I still ended up re-reading pages to make sure I kept everything straight. As a result, I only ...more

At the very hard edge of hard sf's furthest boundary is Greg Egan. One could describe Egan as one who writes fiction for scientists to read. This should not deter anyone else from reading his work though.
The premise here is that (as in Robert Charles Wilson's 'Spin') an impenetrable barrier has been thrown around the Solar System, blotting out the stars.
Nik Stavrianos is an ex-cop private detective in a near future Australia where many residents have been gene-sequenced to produce melanonin and

As good sci-fi should, 'Quarantine' takes an existing area of scientific study, asks the reader to accept a key concession, and turns the dial up to 11. In this instance, the area of study is the observer effect in quantum physics and the concession is that the collapsing of a quantum wave function is a process that is triggered specifically in the brain of the observer. From there it explores all kinds of nuanced philosophical implications, which I won't detail for fear of spoiling the fun.

True science fiction: looking at physics as we understand it (or as it was understood at the time), tweaking one variable (in this case, the quantum 'observer effect') and following the result to its possible outcomes.

Greg Egan does a great job of facing the consequences of his theses head-on - his characters' actions are believable, given their bizarre circumstances, and he doesn't let narrative convenience trump the (not realistic, but consistent) rules of his world.

As a bonus, you get a well-

On the whole, I think I enjoyed this book – film noir sci-fi, sort-of Sam Spade meets the Neuromancer. With an easy pace and well crafted story, the atmospheric narrative rolls along nicely until, about two thirds the way through when, surprise, surprise, we get hit with buckets full of quantum mechanics. The enjoyable narrative romp grinds to a halt while the unfortunate reader is lead through the finer points of particle duality, Schrödinger’s Cat and the ‘many worlds’ universe.

I think - in all my vast understanding of the world - that one of the things that really sets Greg Egan apart is his willingness to drive real physics to its ruthless end.

This is not to say anything against his plots or his characters. On the contrary, I think Egan does utterly absorbing plots and some remarkable characters. But so do other SF writers. There are few others, though, who combine this with a determination to take real-world physics and drive them a long, long way.

Quarantine is a

I woke up at 2:30am and thought I would read just a little before going back to sleep. Instead, I finished the last half of the book and now it's time for me to shower and head out for the day.

Quarantine is a book I enthusiastically recommend to anyone who has read more than one non-fiction book on modern physics by choice. It should also appeal to cyberpunk science fiction fans, as it reminded me strongly of the Deus Ex video games. What's the actual story about? Well, it's about a mentally-aug

Greg Egan is a fantastic hard science fiction writer. Quarantine is a very intriguing novel that tackles quantum ontology. Egan provides his take on quantum mechanics in a story based on the Copenhagen interpretation.

The main character is a PI hired to find a missing girl, and the investigation leads him to an organization that has a stake in a lot more than just missing persons. In addition to quantum mechanics, Quarantine explores the idea of neural mods that can alter the neural pathways in

I kept wanting to like this book, but just couldn't.

The author had one Big Idea (one you would expect from a stoned freshman physics major) and tried to build a book around it. Most of what he used to fill out the book was fairly standard cyberpunk (although, to be fair, it was probably less standard when he wrote the book). There was a lot of text attempting to put some meat on the bare bones idea, but it felt more like filler.

Neil Stephenson attacked the same Big Idea in Anathem. He came at i

One of the coolest reads in a long time.

The novel involves around a Copen Hagen interpretation of quantum mechanics. If that's too mouthful or intimidating, just remember that most decently educated high school students have studied it one time or another. Simply, it is an event of unknown result and once the observation is made, the act of observation itself determines what the end result will be. It is shown in the double slit experiment which should be found in most high school textbooks. The

Un libro que inicia como un misterio detectivesco se convierte en un análisis de los fenómenos relacionados a la mecánica cuántica. Hace una pregunta de lo más incomoda, ¿Y si mediante el uso de software, wetware, implantes, whatever, pudiéramos decidir no colapsar la función de onda de un evento, como observadores de el mismo?.

Si al tirar un dado de 6 caras dividimos el universo en 6 posibles ramas, pero solo una se vuelve realidad al momento de comprobar el resultado. ¿Si pudiéramos "hacer tr

The first book of his I have ever read. It sets out at an investigative pace in 2034 that makes the reader start asking questions at the outset about how humans may engage with brain science and evolved bioengineering using nanotechnology insertions in the future. How ‘mod’ advances could enhance or impose not only on our abilities but our understanding of reality and quantum existence as the plot thickens with twists and turns. Given the latest gadgets available to wear audio-visually the story ...more

The solar system has been quarantined; impossibly encased in an event horizon bubble. However the purpose of the quarantine has nothing to do with the normal clichéd reasons a seasoned science fiction reader might expect but is down to far more esoteric and interesting quantum mechanics.

As always Egan delivers an intriguing and speculative hard science fiction story that is likely to be very difficult reading for anyone not prepared to be immersed in the weird twists of quantum mechanics though

Ya puedo decir que he leído una novela de Greg Egan y no he muerto e incluso me ha gustado. (Axiomático no cuenta porque es una antología) La verdad que la historia de Cuarentena engancha desde el principio, yo no tengo ni idea de física cuántica y el libro se centra sobre eso. Lo bueno es que Greg Egan consigue que, aunque te tengas que leer algunas páginas más de dos veces para comprenderlo,sepas captar la esencia de la ciencia ficción que intenta desarrollar con base en la física cuántica que ...more

"E allora eccomi qui, con lo sguardo fisso nell'oscurità, incapace di decidere se sto osservando l'infinito, o le mie palpebre chiuse."

Uno dei migliori esempi di hard sci-fi in circolazione.
Cosa unisce un'aliena bolla gigantesca che ha inghiottito la Terra, una storia di spionaggio industriale, innesti cyberpunk fisica quantistica e presunte capacità ESP, con tanti saluti a Philip K. Dick? Greg Egan, e la sua capacità di piegare la realtà al suo volere, tale e quale a quella che sperimenta il s

With Egan, you get your sci-fi hard and weird, just the way I like it. It's 2068 and the solar system has been quarantined inside a huge bubble for decades. Nick is an ex-cop private eye hired on a missing persons case. His anonymous client wants to find a profoundly retarded adult who was kidnapped from a care facility, the same one she escaped from twice previously. In the absence of a ransom demand, Nick imagines all kinds of reasons why this woman would be valuable and how she would be trans ...more

I've read 6 Egan books so far, including this one in addition to a short story collection, and each time I come to appreciate his recurrent use of lone wolf, nearly autistic lead characters a little bit more. I grew up reading every Asimov novel I could get my hands on, and to this day I consider the original Foundation trilogy to be nearly perfect science fiction: expansive, imaginative, thoughtful, and most of all, deeply concerned with human problems. But where Asimov's heroes were hard-boile ...more

This book taught me a lot about Quantum Mechanics, and inspired me to dive into the science itself and get a better idea of what he was talking about. Greg Egan is a scientist more than a writer, and thus his fiction has a lot of science in it. A whole lot. It almost reads like a science book itself, so the storytelling will take a bit of a hit here. He's not a bad writer, he just gets a little Crichtonism, in which he wants so badly to push his idea that he takes more time noting it out than he ...more

As always, Greg Egan's writing is excellent. I find, though, that I'm having difficulty with some of his story content. The concept of Quarantine is uniquely clever. I can't fault that at all. And the tag line for the book, "A Novel of Quantum Catastrophe" is as accurate as any I've ever seen.

I found Quarantine a lot easier going the The Clockwork Rocket, in which Egan invented his own version of physics. (Had I read his blog, or had I read the Afterward before the story, I'd have known that and

I didn't know much about this book going into it except that it was a futuristic detective novel. Greg takes the detective story and turns it into a very interesting thought experiment that is very pleasing and fun to travel through. At times he has to use his characters to obviously explain some of the more difficult parts of the physics but he does it well enough that it adds to the story. The switch from detective novel to thoughtful hard sci-fi is well done and I finished the book in a very ...more

Part one shows Egan effortlessly guiding the reader through an espionage mission so that even a non-tech-head like me is swept up in the enthusiastic attention to detail. It's a future in which humans have the technology to insert 'mods' ('modifications', a mental version of our 'apps' today) to regulate their brain functioning. If you're on a stakeout like our hero detective Nick Stavrianos, then the P3 suppresses all distractions, including the need to eat and release. A dead lover can be inse ...more

I'm not going to pretend I know a lot of what was going on here, but getting your head around quantum physics isn't the easiest thing at the best of times. I found the main story really well paced and the scientific/philosophical tangents from the characters written in seamlessly with it. However, the characters seemed one dimensional and the 'Bubble' so inherent to the story was hardly touched upon. But for a fan of hard science fiction, I thought it was great.
Guilherme
A Greg Egan novel lives or dies by how well it explores its concepts - I mean, you're not reading them for the wooden mannequins that no longer have simple emotions get on the way of their discussions of rational futurism.

This book kinda chokes on that. I mean, it's still better than Distress, and it shows the unique physics-distortion that's the crux of the book in an interesting way, but doesn't really GO places. I know that's the whole point, but still.

O sa spun doar atat: o sfera intunecata, de provenienta si componenta necunoscute, inchide intreg Sistemul Solar intr-o capsula care il izoleaza de restul Universului. Pe Pamant, efectele acestui fenomen sunt mimime – practic, viata isi urmeaza cursul ca si mai inainte, pentru ca disparitia stelelor nu afecteaza cu nimic, fizic, planeta.

"Quarantine" isn't my favorite Egan novel ("Distress" is probably my favorite) but since I like almost all Egan, not being my favorite is not a bad thing. In this novel, Egan takes on the Copenhagen interpretation of quantum mechanics, looking at the consequences of consciousnesses that don't collapse the wavefunction and consciousnesses that can chose how the wavefunction collapses. But it's the other factors that I recall better - the effects of ready access to neural implants on society, incl ...more

The rest of the universe has somehow quarantined humanity with a Dyson-sphere-like bubble around the solar system, all because the human brain has the ability to collapse all the possibilities (*eigenstates*) in each quantum event, thereby reducing the potential and actual diversity of the cosmos. Egan takes this premise and asks, "OK, what if someone became consciously aware of this collapsing process and began choosing which eigenstate was made manifest?" What if each moment were a smear of pr ...more

Greg Egan specialises in hard science fiction stories with mathematical and quantum ontology themes, including the nature of consciousness. Other themes include genetics, simulated reality, posthumanism, mind transfer, sexuality, artificial intelligence, and the superiority of rational naturalism over religion.

He is a Hugo Award winner (and has been shortlisted for the Hugos three other times), an
