The Arrows of Time

The time has finally come.

I have finally finished Greg Egan’s Orthogonal trilogy.

There really ought to be a fanfare for such an announcement.

The other books: Clockwork Rocket and Eternal Flame. Spoilers for these two naturally follow.


At the start of his one, Egan himself has written that you just won’t really get this book without the previous two. I don’t think I’ve ever come across the third book in a trilogy that said that so bluntly, and I really appreciate it. Because it is SO true: if you don’t understand how light and time work in this universe (and look, I don’t understand it, but I get how it’s different from ours), let alone the society and what the folks are doing on this mountain-turned-spaceship, you will be so lost you’ll end up in Antarctica instead of Bali.

As the second book was a few generations after the third, so here. The ship is sailing happily through the universe, and folks are still working on how to save the homeworld. Not that everyone especially wants to save the homeworld, from which they are now several generations distant – and will never see themselves anyway. So, classic generation ship angst, really. That’s one issue. Then, there’s what turns out to be a logical consequence of the bizarre universe Egan has set up where light travels at different speeds and some parts are orthogonal to others: that time is affected, too. Specifically, that it should be possible to set a receiver for messages from the future.

Because that couldn’t possibly turn out badly.

So now there are two issues dividing the crew of the Peerless. And just to add to the problems, while the earlier issue about children has been solved – the females no longer need to either die to become their children, or starve to prevent that from happening, and they’re not overpopulating – there are some people who aren’t happy with the solution: especially some brothers who don’t want to be compelled to care for their sister’s children. So life is definitely not rainbows (which they’ve never seen) and roses (which they don’t grow).

I love that Egan tackles such weighty topics as democracy, needs of the few vs needs of the many, the importance of choice, the place of parenthood, and so on – all in a book that literally has vector diagrams in it as it explores the outcomes of a thought experiment in physics.

From a narrative point of view, the most gripping part is when four people travel to an orthogonal world to see whether it would be habitable. Again, this is an exploration of the consequences of ‘orthogonality’; time is literally going in the opposite for this world from how it is experienced by the travellers, so what could that possibly look like? What does that, what can that, mean for free will? (A whole bunch of headaches is the answer. Mostly metaphorically.) This bit is also a deeper exploration of the characters, as they interact only with each other, in very trying circumstances.

As with the other two books, I admit that I skimmed bits of the physics explanations. Including the diagrams. I read it well enough to get the point Egan is making, but I would in no way attempt to explain it.

I have a couple of thoughts that are spoilers, so don’t read the rest if that’s a problem… but if you’ve read the first two, I think you definitely need to see how the story plays out.

Another in my long slog towards Reading Everything By Greg Egan, Dammit.

When I started this last week, I was completely thrown: it was familiar. Like, I had definitely read this before. Yet I had definitely got it from the TBR shelf, so… wha? I thought about it, and I didn’t remember the ending, but let’s be honest – that’s not exactly unusual for me. So I read a few more pages – still familiar. I read ahead 20 or so pages – getting less familiar. Eh; I decided just to keep reading, and see what happened. Turns out that at some point, I read the first 50 or so pages, and then gave up. I have no idea why I would have given up at that point, because it’s not even like this is a particularly hard book as Egans go.

UnknownThat is to say, if you don’t like entire pages of dense scientific discussion and you’re not the sort of person who is happy to skim that to get back to the plot, do not read this book. It’s ok; it’s no reflection on you; it’s just not going to be a happy match-up between the two of you and it’s not worth your time getting annoyed.

Even more than any other Egan until the Orthogonal books (The Clockwork Rocket and Eternal Flame), half of this book is unashamedly working through a scientific revolution. In a society where things just are the way they are and curiosity isn’t rewarded – cooperation and teamwork are, hormonally – one misfit manages to co-opt a fellow worker into being curious about the way weight changes in different parts of their habitat, and… from there, you get an explosion of scientific discoveries. How does that even work? What sort of questions do you even need to ask in order to discover basic principles of gravity, for instance? Egan throws himself, and the reader, into these issues – without forgetting that they occur in a vacuum, and therefore also incorporating discussions of social change and disruption and, because this is Egan and it’s just what he does, a bit of gender role discussion as well.

Seriously. This man.

The other half of the book is a slightly more straightforward SF plot, where the far-future equivalent of a bored early-20-something seems to handed the puzzle of a lifetime and he sets off on a joyride around the galaxy, complete with sidekick. Well, not quite, but close. You could definitely take these chapters and have a fairly good SF novel, anyway, about the differences between living in the disk of the Milky Way and living in the bulge, and how you might go about being a detective with all sorts of cool gadgets (wait til you read about the telescope they construct). The reference to the sidekick is a little unfair; Parantham is not just along to have ideas bounced off. He/she is an undeveloped character in many ways; not descended from DNA but rather – to put it crudely – from AI, Parantham allows Egan to suggest issues around body perception and suchlike but doesn’t do that issue justice. The not-quite adolescent, Rakesh, verges on petulant and annoying and just manages to avoid being such, most of the time. Their interactions are interesting enough and certainly add a different dimension to the novel overall.

In the end, I enjoyed this. It’s not Egan’s greatest, by any stretch. It’s a clever way of thinking through some scientific issues, and it has some nice character moments. Probably not the place to start with reading Egan, though.


I really thought this was going to end with Rakesh helping the people of the Splinter, and with a discussion of the role of the Aloof. As the pages kept turning and there was no actual contact, I just could not figure out where Egan was going with it. When I got to the last page, I admit I was flummoxed at first. But then I realised: Rakesh had been interacting with much later generations of the Splinter. They weren’t happening at the same time, at any point! Not that Egan had ever suggested they were, of course. I quite liked this.

Diaspora, Greg Egan

The same caveat applies to this book as to every other Egan novel. If you are neither inherently fascinated by mathematics and physics taken past the bleeding edge, nor willing to tolerate possibly pages of physics discussion that you don’t get, then don’t read this novel. It’s not the book, it’s you – and that’s ok, it’s just not worth your while getting frustrated.

That said, if you’re willing to dive in, I think this is another of Egan’s awesome novels. Spoilers coming.

Greg Egan_1998_DiasporaThe premise is that at the end of the 30th century, there are some humans we would see as ‘normal’ – called fleshers here; there are more ‘people’ who inhabit the polises, which are basically massive computers – so yes, they’re virtual, from our current perspective. And there are also gleisners, who inhabit robot bodies. The plot is driven by the perspective of a couple of polis citizens; indeed it begins with the creation of an ‘orphan’, a citizen in a polis created with no input from any parental guidelines but by the polis itself, basically to test new possibilities. This orphan, who becomes Yatima, is a primary protagonist.

Some reviewers over on goodreads have been frustrated by the lack of fiction, or plot, in this story, and I can see where they’re coming from. However, there is a plot, and even if sometimes it takes something of a backseat to the ideas – well, that’s kinda the deal with an Egan story. But it’s not superfluous in any way. So what is it? Well, a gleisner astronomical survey indicates that two neutron stars are about to collapse into each other, several million years earlier than they ought to. They’re frighteningly close to the earth, and it does indeed do very bad things to the planet when the gamma rays etc get here. From this, eventually, there is a diaspora as people (broadly understood) attempt to understand this event and how to survive future ones and also, just Going Out into the universe as humanity has always dreamed of doing. Interesting things are discovered, of course.

This brings me to a rant about the blurb. It suggests that Yatima is searching for a world where no “acts of God” will occur. Um, no. If anyone is searching for that it’s Orlando, a flesher who goes into a polis after the catastrophe. But even that does absolutely no justice to anyone’s motivation. So… all I can think is that the blurber had no idea what to say about the book, and was told to focus on the plot (which they didn’t understand) rather than the ideas. This is my contempt you’re feeling right now.

And then there are the big questions Egan plays with. Some of these are things he’s actively working through over the novel, while others are things he simply takes for granted. For me, as always, his approach to gender is the most striking on a plot level. Because it’s one of the issues he simply takes for granted. Humanity living in a software-created virtual world? Why on earth would they keep to rigid binary (yes I know, all the caveats about it not actually being binary) understandings of gender? So most of the polis citizens are referred to as “ve” – and things happen to “ver” while belongings are “vis”, which is very neat. There are some who are gendered; Orlando, perhaps understandably, can’t shed his original gendered self perception; there are some polis-born citizens who also insist on it, and they’re regarded as frankly a bit weird. I adore this aspect.

The virtual nature of much of the story could lead to a complete divorcing from the physical, which is an issue I’ve been thinking a lot about since reading Nike Sulway’s Tiptree speech: the issue of divorcing matter and mind. However, I think Egan does a good job here of not doing so – and indeed of interrogating the issue. The polis inhabitants do still interact with matter, and it is important to them; there are discussions about the importance, or not, of interacting with the real and whether postulating crazy things like more dimensions than we can see or interact with is just offensive. Most polis citizens respect the material world even if they experience it differently from fleshers. And the diaspora, even if it takes places as (basically) flying computers, also interacts with the real and physical in important, fundamental and profound ways. So, go you, Egan, for not just going the lazy cyberpunk route.

Did I mention that this book takes place quite seriously over about two millennia, and then speeds up at the end to encompass even more time? What a head spin.

Some of the physics stuff he discusses: astronomy – especially the neutron star bits; extrasolar planets; alien life, including evolution and non-carbon-based possibilities; wormholes; quarks, leptons, fermions etc; and the possibility of other universes and how they would interact, or not, with the one we inhabit.

On that note, I can’t help but feel that this must to some extent be Egan’s answer to, or take, on Flatland. Indeed he references the idea of “flatland” at one stage. Because some of the characters are forced to interact with beings existing in 5 dimensions, and how are you going to do that? So that’s a really nice aspect for those who have read that somewhat obscure adventure into dimensional maths.

Some of the other ideas that Egan confronts: human evolution, both ‘natural’ and deliberate, and what that will mean for the various branches communicating with each other; the place of art and of mathematics; cloning, and its possibilities; parenthood and the nature of being an orphan; individuality and community.

I told you this was a dense, complex, and – I mean it – ambitious work, right? You can get it from Fishpond. 

Greg Egan: Quarantine

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.

200px-Quarantine_(Greg_Egan_novel)_cover_artQuarantine is a case in point. Take the idea that quantum mechanics suggests, that of collapsing probabilities as a wave function and the role of the observer in doing so. (Dear scientists, if I have just or am about to claim the equivalent of the Dark Ages being a real thing, please let me know and forgive me at the same time.) This leads to the many-worlds theory, whereby every action spawns alternate worlds where that action was done differently.

Now extrapolate to its ruthless conclusion.

Now add a detective thriller plot.

Now add a world in which there are no stars – they went out some decades ago.

Add the ability to mod your brain (turn off boredom, modulate emotions, change memories and attachments).

Add a world where Arnhem Land has become an autonomous nation and offered part of its land to become New Hong Kong.

… and you begin to get an idea of what Quarantine is like. Seriously, just a few of those things could make for a great novel. But they’re all there. Some are just part of the world-building, some are fundamental to the plot, all work cohesively together to produce a book that I read in a day (it’s only 250 pages, ok? And there are no formulae in this one, unlike the Orthogonal books).

I am never bored by Greg Egan, I am never impatient with Greg Egan, I am consistently surprised by Greg Egan. This is another good one.

You can get Quarantine from Fishpond.

The Eternal Flame

The following will include spoilers for The Clockwork Rocket, which I discussed over here.

A universe where parts of the spectrum of light travel at different speeds. A race where mothers cannot exist. Vector diagrams. They’re overused, but I’ll use them anyway: Egan is nothing if not ambitious and audacious.

Unknown A warning: the same issues that pertained to Clockwork crop up here. It is most definitely not a book that will work for everyone. You have to fall within a fairly specific range of readers: either someone who really enjoys thinking about physics and won’t be weirded out by the bizarre physics Egan is working through here; OR someone who is willing to skim over the vector diagrams and other physics-lecture bits, and just enjoy the story. Personally, I’m the latter. And the only reason I was willing and able to push through the physics was because I trust Egan to give me a really worthwhile story between, or around, it. I kind of imagined that I was listening to a really, really interesting person who occasionally meandered into talking about stuff I didn’t get, but was bound to get back to the good stuff eventually. And I was right.

The point of the Orthogonal series is to explore two central ideas: how the universe might be different if the speed of light isn’t constant; and how society might be different if mothers didn’t exist – or rather, they cease to exist at the point of childbirth. The story revolves around these two issues, and does so in occasionally remarkable ways. The physics aspect is very much an intellectual exercise; if there is commentary on modern science, aside from the obvious bureaucracy-getting-in-the-way, I missed it through not understanding enough of it. The biological/social aspect, though, includes a huge amount of commentary on modern Western gender relations, and it’s confronting, frightening, and sometimes scathing. I loved it.

Clockwork ended with a crew aboard the Peerless – a mountain launched into space – setting out with the objective of experimenting and thus hoping to find a solution to the probable destruction of their home world by an oncoming storm of meteors. This is only possible because of the different way light and time work in their universe; by moving away and then retuning home, much more time will have passed for them than on the planet. Because of the discoveries and attitudes, I’ve seen this book described as mirroring the Newtonian/seventeenth century European scientific revolution, which I think makes some sense but I wouldn’t push it too far. Along with the very pressing problem of saving the world, the crew carry in their bodies another issue – an issue that was only just being recognised as an issue: the fact that a mother’s flesh splits into her (usually four) children at ‘birth’. Mixing up the historical periods, this might be seen as somewhat comparable to the long period between Mary Wollstonecraft (late eighteenth century) and the suffrage movement of the early twentieth century (…. would that make Yalda both Ada Lovelace and Millicent Fawcett?? I Unknown Ada Lovelaceam loving this idea, daft as it is). Women are starting to think that there might be alternatives to simply living with their co and eventually becoming their children.*

To continue this intriguing historical comparison, Eternal Flame is scientifically moving into an Einstein/Hubble frame of thinking, and socially (I can’t believe the gall of this sentence) into the second-wave feminism of the 1970s (I wish there was an author in the story that I could tag as Joanna Russ, but there’s not). In physics, in particular, there are astounding discoveries being made about the properties of light and heat which are beginning to have profound ramifications for how they think about solving their problem (problems actually, since they also left their planet with no way of getting back with the solution…). Socially, the crew has pretty much always accepted women as being just as worthy in science and other jobs as their male counterparts – not least because many of the crew, especially in the sciences, were women. However, biology is still an issue. The original women used a drug, holin, in order to delay the onset of fission (birth). By this stage – three generations later – still use holin but are also basically starving themselves, for two reasons: both to delay birth, and in the hope that their fission will result in two, rather than four, children. Because the Peerless has experienced a population explosion, and they cannot support every pair becoming five. So (to get back to my comparison), the right of a woman to decide when to have children is one of the big issues – as it was with the introduction of the pill and the controversy over abortion (which I know is still ongoing).**

There are three narrative strands going on here, which frequently intersect but deal with different issues for the ship. I assume they’re meant to be of equal importance, but I’ll be honest and say the one that dealt the most with pretty full-on physics definitely took a bit of a backseat for me, even though I could see how vital it was to the story’s point. Carlo is investigating biology and fertility; both the fact that animals appear to exchange information somehow via infrared… something… and the fact that some animals seem to have adapted to biparous fission very easily. Tamara is an astronomer who observes a massive object outside in the void, and develops an audacious plan to use it somehow. Carla, a physicist, is investigating the properties of light and energy and challenging a lot of preconceived notions in the process.

The novel as a whole does involve a lot of physics-lecture stuff. There really are a lot of vector diagrams, and graphs demonstrating energy levels, and… other things. The biology doesn’t get quite the same treatment, perhaps because it’s not quite so radically different from our world. However, the science is not the be-all of the novel – if it had been I probably wouldn’t have persevered. There’s a bit of action, with an excursion out to the Object Tamara observed and some other dangerous moments for characters I had grown fond of. There’s some great character development, in particular as different people consider the biology issues for themselves and reflect on what it means for them individually and as a society; a few make very surprising decisions that are nonetheless entirely consistent. Being set on a spaceship, large as it is, means that the story is necessarily constrained; keeping the focus on three main protagonists helps with it not feeling claustrophobic but rather focussed, which is also aided by making them active in such different spheres. The physics and biology dominate, as discussed; there are also undercurrents of the frustrations of bureaucracy and the impact of history – after all, this is a generation of people working towards solving a problem for a world they have never known.

If you want to be read a science fiction series that will really challenge you scientifically while also (largely) being very readable, coming complete with a compelling storyline, this is it.

You can get The Eternal Flame at Fishpond.

*I’m well aware that this is grossly unfair and generalising to the women before Wollstonecraft, and in fact Egan does not make it nearly so clear-cut; as with real European history, there have always been women who bucked the trend in this world, too.

**I have no idea where Egan could go with this historical comparison for the next book. Still, it was fun while it lasted.***

***I’m not suggesting Egan did this deliberately. I’m quite sure he didn’t.

Zendegi: a Greg Egan novel

Unknown 4.26.07 PM

My e-copy of this book categorises it as “Fantasy; short stories.” It is neither. Rather, it is a near-future novel about politics, virtual reality, religion, family relationships, and death.

No, it is not a Patrick Rothfuss or George RR Martin-style tome. It is elegant.

Two strands: Nasim is an Iranian woman living in America, working on the mapping of individual finch brains to try and create a generic brain map. Martin is an Australian journalist working in Iran, who gets to cover escalating political unrest. (This book was published in 2010….) Flick forward several years, and Nasim is living in Iran and now working on Zendegi, a virtual-reality platform used by millions of people, mostly for entertainment. Martin is still in Iran, married with a son. I trusted that the two strands would eventually cross, but I really couldn’t figure out how. The answer is both ‘cleverly’ and ‘via tragedy’ (Egan, you are nasty).

I am in serious danger of becoming quite the Egan fangirl. Just so you all know.

Egan does a marvellous job here of entwining the intimate and domestic with large-scale societal issues. Personal tragedies are neither hyped up to become world-ending nor elided as insignificant. The plot moves carefully between, for example, Zendegi as entertainment for a six year old and Zendegi as bleeding-edge technology – and how the company can deal with competitors. Egan portrays politics as they are seen by a slightly-above-average interested citizen, rather than focussing on politicians; he touches on religion as it might be experienced, rather than trying to show rights and wrongs. He’s a sensitive and compassionate author, but did I mention nasty? Also, I think he writes women well, which is something I’m coming to appreciate more and more. Nasim’s feelings of anxiety over having left Iran, and wanting to return, read realistically. In fact, overall human attitudes and relationships read as believable: complex and contradictory and frustrating and glorious.

In a more classically cyberpunk novel, Zendegi would get far more of the focus that it does here; characters don’t actually spend that much time in the virtual world, for example. It is incredibly significant for both Martin and Nasim by the end, but still I am a little surprised by its use as the title. I think Egan has hit on a more likely way for virtual entertainment to encroach on our lives than most early cyberpunkers did – more subtle, and perhaps more insidious for the fact. It’s really nicely presented.

This is a novel brimful of complex and challenging ideas that is an absolute, pretty much effortless, delight to read.

You can buy Zendegi from Fishpond.
