Wireheads: "The Ringworld Engineers" by Larry Niven

(Original Review, 1980-12-20)

Reading some people's complaints about unpleasant events in SF (e.g. Louis Wu becoming a wirehead in "The Ringworld Engineers") reminded me of an article in Analog some time back. It was written by a founder of a company that would keep you in cryogenic storage until a cure was found for your disease, or the Messiah came or a John Bircher became president o

Like its predecessor, Ringworld, I really liked the overall ideas of this book: a massive, artificial, circular world that needs saving, varied hominid species filling all ecological niches, non-humanoid alien species that act in a truly alien manner, and a hodgepodge group of heroes. However, the main character, Louis Wu, is portrayed as God's gift to any female hominid; if it's anatomically possible for him to sleep with someone, he does, basically. The Ringworld revolves around sex between sp ...more

The sequel to Ringworld, this has a better story. The characters go on an adventure in which they explore, experience and come into conflict with a lot more people. Niven is incredibly original, designing entire cultures, civilizations, and unique creatures behind the history of Ringworld. This book explains a lot of the mysteries found in the first book, and introduces more. Niven fixes some engineering and ecological gaps that were left in the original, and expands greatly on the plot found in ...more

And so we return to Ringworld, with Louis Wu and Speaker-to-Animals, who have both undergone character development in the interim. We get a new Pearson’s puppeteer, though I much prefer Nessus, who had some dynamism.

Niven is now free to present major obstacles in the Ringworld, and he does so within a typical, though exciting, plot. The stakes are high, no less than the fate of the Ringworld itself and its trillions of inhabitants. We get up close and personal with many of those inhabitants, to

I don't know what happened in this book. I mean. The first book was decent. Not great, but not terrible. Most things followed from other things and you know, it was OK. This one was all over the place. There were lots of good ideas but most of them were just set out without any kind of proper foreshadowing or setup.

Take the origins of humanity (and the creators of Ringworld) - what would be a huge, fascinating reveal in any well-written tome - it's a huge flop here, an afterthought. AND I get ho

This book is an excellent squeal in that it answers almost every question that came to mind after people were done reading the first one. This book is about a voyage back to Ringworld, it gives much more detailed information on the Ringworld, and tells what happens to some old characters like Teela as well. If you were lucky enough to experience the first one, then you must experience the second.

Este es el segundo libro de la serie Mundo Anillo,
me ha gustado mas ya que no solo son descripciones difíciles de imaginar,
aquí otro tinterote secuestra a Luis Wu (quien se ha convertido en un adicto)
y al afelpado Kzin para volver a explorar el mundo anillo
en la búsqueda de una máquina trasmutadora de materia.
En esta exploración contactan con mas especies,
donde cada una aporta su concepto del mundo anillo.
Es increible lo central que es el sexo para este autor
ya que cada contacto involucra sexo

(2013 was turning into a stale year for SF. That summer, I really needed the solace of good, hard SF to escape, if just fleetingly, some harsh realities, same reality having given me long days and nights to read and listen. So, without really making a decision to do so but compelled by circumstances, I started a re-read of the Ringworld series. The publication history of the series was such that one book came out every ten years, on average. And so each book read provided a reflection of a deca

I wasn't sure if I wanted to read this book to start with because of the change to Louis Wu's circumstances at the start of the novel (he's a junkie, addicted to the pure pleasure of electrical stimulation of the brain). But that actually turned out to be one of the more interesting things about the book. Why would a character as obviously strong as Wu turn to the wire? That question does get answered, along with the other obvious question of what he does next. Perhaps his escape from addiction ...more

As the series progresses, I continue to enjoy Niven's clear style of writing. He makes the hard science interesting. We learn more about the Ringworld and get a little deeper into the character Louis Wu. While I recommend this as an enjoyable read, I couldn't give it more than 3 stars because of the predictable plot. But there are enough surprises and revelations to entertain the Ringworld / Niven fan.

As an example of what I like about Niven is the scene where the puppeteer looks into his own ey

I didn't love Ringworld. It was with much goading that I read the second one. With so much love for the series, I do wish that I liked it more. But I had fewer instances in this volume where I felt bored. I have not yet connected strongly to the characters, and I'm still a bit put out by the tendency for women in the series to be relegated largely to the role of thing for the main make characters to have sex with.

Louie Wu is addicted to the electrical current drilled into the pleasure center of his brain. But when attackers come to capture him - he is still capable of taking care of himself. At least for the first set.
Louie Wu and Speaker-to-animals are hijacked by a puppeteer and taken back to Ringworld to search for the mass transformer.

When they get there, they find that Ringworld is on a slow decline into the sun. Louie promises to do something about that and this is the story of this act of herois

The feeling is too much of a sequel and it's so uneventful and unsurprising that all I could say would be spoiling. I was really captivated by the fisrt so I went ahed of my self and bought the second and third book. Now I have the 3rd and I have to say the the last 50 pages of this one were already quite hard to finish. The Ringworld was such a great idea that it become the prison (so far) for the narrative and the characters, it's like all the imagination was confined to this construction and ...more

I like the continued exploration of the ring. More details about the people and the ring itself really expand the world. I also found it interesting how the origin of the ring was explained as well as how it tied to humans.

I think it’s cool how the author took analysis and input from the fans of the first book and incorporated them into the story.

Far more interesting than the first installment of the series. So far, Ringworld and Ringworld Engineers are the only books I've read set in Niven's "Known Space" universe. The first book may have taken certain things for granted that weren't sketched out fully enough for me to appreciate the nuances of characters, places, events, whereas I felt this book did a better job of introducing ideas from the background shared by the Known Space books.

I had a lot of fun reading this book. Niven is great in combining the can do spirit of classical SF with modern physics and has the imagination and knowledge to make up something like the titular Ringworld and people it with the most fantastic inhabitant. The idea of an ocean so large that 1:1 maps of earth and other planets are just islands in it, is truly awe inspiring. And I liked the ecologies of adapted humanoids, the battle againt the sun flowers and even the 'cold equations'-like dilemma ...more

Strangely, I found this book better than the original Ringworld. The story is more compelling (you begin to care about what happens to the characters by the end) and the aliens seem a bit more fleshed out, though we do see less of the puppeteer dynamic. My biggest complaint is that the falling action at the end feels very forced, as if the publisher was begging him to write a book, not a brick. It felt like there was more to tell, and we only got four pages.

Again, I think that other books have d

I can hardly remember the original Ringworld anymore (it's been a few years already), but I really hope it was much more better than this. I seem to have given it (out of memory, as I read it pre-goodreads) a rather large score.

The Ringworld Engineers ... well, if I want to be kind, I'd say perhaps its naive or simplistic. Otherwise, I'd have to rant too much here. Pointless sex scenes, the humans will solve everything (the sci-fi version of Americans solve everything), we'll also figure out vas

Larry Niven is amazing! In Ringworld, he dares to think bigger than just creating a universe -- he creates sentient beings powerful enough to create a solar systems and he builds solar systems unlike any other. In the process, he also creates a mystery that keeps you looking for answers that he never provides.... until Ringworld Engineers.

Overall, not as impressive as I had hoped. It tended toward the pedantic, with a "Been there; done that" sort of feel through many spots. Sure, there was interesting material presented in many chapters and interesting problems to solve on occasion, but the novel was way too episodic: Go somewhere new, discover some problem, then have a sudden and fortuitous event, condition, or insight occur to magically fix everything, allowing the character to leave; end the chapter. It became dull.

Niven's first sequel to his classic Ringworld fully lives up to the standard of the original. Here we see the cultures and the engineering of the Ringworld in finer detail than before, all framed by a more plot-driven narrative. We also get a nice look into the psychology of Pak Protectors via a surprise guest appearance. The climax blends philosophy, reason, emotion, and pure action to an extent that the first novel never touched.

The Ringworld series continues with this book, The Ringworld Engineers. Some of the same characters appear from the first novel, most prominently, Louie Wu and Chmeee. Louie and Chmeee are kidnapped by a Puppeteer and taken back to the Ringworld to search for an artifact that will help the Puppeteer to his political aspirations. I thought this book was a little confusing and had too much rishathra (sexual practice outside one's own species), which had nothing to do with furthering the story. I d ...more

This is a bit of a game-changer. It really makes me respect an author when I excitedly pick up a sequel anxious to catch up on the characters I have grown attached to, but then only to discover the author had very different plans than I did for them. Almost like a triumphal 'fuck you and your preconceived notions'. Well Played sir.

Engineers takes that step, but it is a wonderfully unexpected continuation of the gigantic mystery that is the Ringworld. It really took this 2nd book for me to grasp

I want to say there was far more that was explained in this book than in Ringworld, but it sort of ended up resembling Lost where every answer just spawned more questions... like trying to cut off a hydra's head. Some parts left me going "Wait, what just happened?" because the characters had obviously just connected some dots that I wasn't tracking with. And yet I enjoyed the whole ride, confusing plot points and near retcons and all. It was a fun adventure to read and trying to analyze too much ...more

Este autor está banido das minhas opções de leitura, até ao fim dos tempos.

Li este livro baseado na promessa (explícita no título claramente enganoso) de que, finalmente, o autor desvendaria (de verdade... algo que justificasse a leitura de recheio de chouriços) o mistério acerca dos construtores do "Ringworld", e a razão (convincente) para a existência de tamanho artefacto. Não. E não. Eu devia ter aprendido com o primeiro livro.
