Review 92: The Door Into Summer

The Door into Summer by Robert Heinlein

Oh, 1950s science fiction - is there nothing you can't do?

One of the downsides to our modern information age is that we have so much information available to us. If I see a reference on a blog or in a book that I don't know, it's a quick hop over to Google or Wikipedia to find out what it is, and if it's really interesting I can find myself learning about something I never knew before. And so, if I want to know more about cold sleep, robotics or time travel, there's a whole host of ways that I can not only learn about it, but learn why it's just so hard to do. I mean, think about robotics - we've been looking forward to the perfect household robot for decades now. One that can cook and clean and do all those tiresome chores that we would rather not spend our time doing. The problem is that those tiresome chores are actually marvelously complex tasks, involving not only precise physical movements, but some very complicated judgment calls. Every time we figure out how to get a robot to do one of those things, we then have a hundred other things that need to be done to get it even close to human-like competence.

I know this because the internet knows this.

But back in 1957, this stuff was all new and fresh and unknown, so if Robert Heinlein wanted his main character to cobble together the perfect household robot with some off-the-shelf parts and a little bit of magic tech (the Thorsen Memory Tubes), then why not? Assuming we had the technology, what couldn't we build?


Thus is the set-up for The Door into Summer, an adventure in engineering, patent law, and economics, with a little bit of time travel thrown into spice it up. Our hero, Daniel Boone Davis, is an engineer of the purest sort - he got into engineering to solve problems, and that's what he does. He doesn't want to be just one guy working on one cog for a huge corporation; he wants to make things himself that he knows will benefit everyone. He's a real Populist Engineer, too - his creations are made with replaceable parts, specifically so that the owner can quickly deal with any mechanical problems themselves, rather than have to wait for a repair shop to do the work. The parts are all off-the-shelf, too, which not only makes the machines easier to produce, but makes the production cost lower. In other words, he's making machines that will benefit as many people as possible, and the first one is the somewhat misogynistically-named Hired Girl.

This machine (which is a very close approximation of the Roomba, by the way) becomes an instant success, and the company that Dan forms to take care of it is looking to become fantastically wealthy. Unfortunately for Dan, his business partners - Miles and Belle - are far more interested in becoming filthy rich than helping mankind. So when it looks like Dan's newest creation, an all-purpose household robot named Flexible Frank, is going to be a wild success, they manage to freeze him out of the company. Literally. They steal his inventions out from under him and force him to take the Long Sleep - to be frozen cryogenically for thirty years. He wakes up in the year 2000, without money, without a job or prospects, and without his beloved cat, Pete.

A word about the cat angle to this story - if you're a cat person, like me, then the relationship between Dan and Pete will really resonate with you. Its clear that Heinlein himself was a cat person, as he shows a wonderful understanding of the human-cat relationship, including the absolute uncertainty as to which one is in charge at any given time. While the cat is not absolutely necessary to the plot, it's a nice addition to the story. If you're not a cat person, well... you should be.

Anyway, in the wild future of 2000, Dan discovers that something very strange was going on around the time he got frozen, and the more he uncovers, the more it looks like there can be only one explanation - time travel!

This is really classic science fiction at its best. The narrator is a brilliant man who never meets a problem he cannot solve, at least not eventually. He's a certified genius, and were it not for his blind spot for pretty women and his trust in his business partner, he would have had a fantastic life as an inventor. But his love of making stuff gets in the way of how the real world works, and sets him up for a series of thefts and betrayals. But you never really worry about him, because he is a man with no uncertainties. He doesn't wallow in self-loathing and moral dismay when he encounters a problem like being thirty years in the future with no means of supporting himself. No! When he sees a problem, his first thought is, "How do I solve this?"

In other words, he's an engineer.

It's a remarkably optimistic book, too. While the future of 2000 isn't perfect, it's still a whole lot better than 1970. And while 1970 certainly isn't perfect, it's a whole lot better than 1957. The book rests on that wonderful mid-century assumption that while human innovation can't solve every problem (and indeed often succeeds in creating more problems), it is, in the long run, a force for good. For the modern reader this may seem terribly naive, but I found it refreshing.

So while the story is really pretty predictable, it's a fun ride. Even the time travel element isn't quite as risky as Heinlein tries to make it out to be, since the reason Dan opts for time travel is that he's found evidence that he's already done it. Therefore no matter how dangerous it might be, he knows for a fact that he'll be successful. He doesn't mention this, or even seem to notice it, but the sharp-eyed reader should pick it up pretty quickly.

While most of the driving force of the book is what I would normally consider pretty boring - patent law and engineering - there is one element to it that is distinctly Heinlein: the universality of love. Dan is done in by his belief that he loves Belle, who turns out to be a gold-digger of the lowest order. But in the end, Dan knows who he truly loves. The only problem is that she's an eleven year-old girl. Whether in the publication year of 1957, the year Dan starts in, 1970, or the far-flung future of 2000, a grown man marrying a pre-teen is something that is generally frowned upon. They're able to settle this problem with a little time travel/cryogenic jiggery-pokery, but when you stop to think about it, the situation can be somewhat... unconventional. If you stop to really think about their relationship, there's some strange moral ambiguity going on there. Fortunately, the characters don't really care and the book ends without going into the ramifications of what they've done.

The book isn't about moral complexity, though. It's about solving problems and finding happiness, no matter what you have to do to get it. It's about overcoming adversity, betrayal and even time itself to get the life that you know you deserve. It's about finding that door into summer, when all the other doors lead you only into the winter. While we may not be able to solve our problems quite as neatly as Dan Davis did, we can still follow his example.

Except, perhaps, with the romancing eleven year-olds. That's still not cool.

Review 48: The Green Futures of Tycho

The Green Futures of Tycho by William Sleator

It's always dangerous to revisit a book that you loved when you were a kid. Everyone knows that. Some books are really just geared towards a certain age, a certain time in your life where that book can step in and say, "Here - someone knows what you're thinking about." And those books are amazing. You read them and your life changes. Maybe only in small ways, maybe in ways you don't even realize until later, but it does.

Then you come back to it ten or twenty years later and think, "I remember this book. I loved this book. I think I'll read it again." So you do, and it's a disappointment. Not because the book isn't as good as you thought it was but rather because you aren't the person you were when you first read it. There's nothing wrong with that - it's just life.

When I ordered this off Amazon, I did so with a certain amount of trepidation. This book occupies a very special place in my heart. I read it over and over again when I was a kid. It instilled a love of time travel that I keep to this day. I even adopted the name Tycho as a pseudonym for various parts of my own mind all the way through high school and beyond. I knew that re-reading it would put that entire past at risk of becoming foolish or stupid or childish, and I wasn't sure my ever-vulnerable pride wanted to take that.

Fortunately, I discovered that the book was as good as I recalled it being. Shorter than I remember, of course, but still quite good.

The story is deceptively simple - Tycho Tithonus, the youngest of four siblings - the other three being very talented and thoroughly unpleasant - finds a small, silver, egg-like object while digging up a new vegetable garden. As innocuous as it seems, that object is about to change everything. It is, in fact, a time machine.

It's not very difficult - it has a series of dials on one end, which you turn to set the time you want to go to. Press the other end and it's done. And Tycho does what anyone would do when presented with such an amazing device: go back and re-work an unpleasant event in his past. And if by doing so he could maybe teach his nasty siblings to appreciate him more, well, so be it. Of course, the ramifications of this act don't become clear until it's much too late.

But the past doesn't really hold that much allure for young Tycho. It's over and done with, and was never very pleasant to begin with. So he decides to go to the future, to see what has become of himself and his family. A quick twenty-year jump to April 23,2001 shows him what's in store for himself. A desperate, unhappy, bitter man, fronting for a lunar entertainment industry and reduced to begging sponsors for money.

Disappointed and upset, Tycho comes back. Later, he visits the future again - same day - only to find it has changed completely. He's no longer a sad, shapeless man but a tough, ruthless one, a man who uses his ability to travel through time to make money and ruin his family. Terrified, Tycho returns to his own time. But his curiosity can't be stopped. He needs to see a future where everything works out right. Unfortunately, every time he goes there it's worse and worse. His future self becomes a monster and a murderer, a willing agent to bring beings of higher power onto this planet.

This is one of the things I've always liked about Sleator - his mind turns around corners. Everyone and his uncle can write about a time traveler going to the past and changing the present, but who writes about someone changing the future by messing about in the present? Not many, I'll tell you that. Each time Tycho comes back from the future, the knowledge he has gained causes him to say something or do something that alters the course of his future in a new and terrible way. And seeing how much worse it gets just forces him to make even more terrible decisions, until you have the final, terrible paradox of an old Tycho trying to chase down and kill his younger self over the course of millennia.

Which does bring up the problem of paradox, unavoidable in any time travel book, known in fiction as "massive, gaping plot holes."

For example - if Tycho time-travels twenty years into the future to see his older self, there shouldn't be any older self there for him to meet. It's impossible - as far as the rest of the world was concerned, Tycho vanished on April 23, 1981 and re-appeared twenty years later. Everyone else lived through that time, but he simply side-stepped it. Instead of finding a letter from his older self to his mother in their future house, he should have found perhaps a black-framed picture of 11 year-old Tycho with a note to the effect that they should have loved him more. The only way I can think of to resolve this problem is to assume that Tycho was absolutely and incontrovertibly determined to return to his own time after each future visit, thus ensuring that he would eventually live out those twenty years.

Fortunately, Sleator handles these paradoxes in a very simple and straightforward manner. During one of Tycho's experimental first trips into the future, he meets his teenage self, who shows him how the dials work on the egg:

"But," Tycho said. "But if you're me... I mean, if we're the same person, how can we both be here at the same time?"

"No time to explain now," said the other Tycho, bending over him. "I've got to show you how to work this thing, fast, so you can get back to your own time."

"But that doesn't make sense," Tycho said, more confused than ever. "If you have to show me how it works, then who showed you how to -"

"Shut up and concentrate."

There you go. That bit there is the author saying, "Yes, I know there are paradoxes involved, but that's not the point of the book." That pretty much sweeps aside all those little picky details, like older Tycho trying to kill his younger self, or the fact that, by the end of the book, the entire story didn't, technically, happen. "Shut up and concentrate."

He handles the alterations resulting from time travel very neatly as well. Rather than beat us over the head with "Things have CHANGED!" he just inserts a simple descriptive line in there. If you're reading carefully, you'll notice that Ludwig's hair has gone from proto-emo long to a nice crew cut. Even Tycho doesn't notice, which is interesting. When presented with the results of a change in time, he has a moment of jamais vu - the feeling of something familiar as totally new - and then the story moves on. The effects multiply and resonate, and even Tycho isn't aware of how much he's changed.

Going back to the plot hole problem for a moment, there is the small issue of the egg's origin and purpose. We know it was planted on Earth by aliens, something like 150 million years ago. It seems they did so with the intention that it one day be found and used in order to prepare the way for their arrival and dominance of Earth - this is what can be gleaned by the ravings of older Tycho. But why would an alien race which has time travel sorted out need such a roundabout way of conquering the world? Why drop it into some Jurassic mud and leave it at the whims of plate tectonics? Why not just show up at Tycho's house one day and drop it on his bedside table? This is never adequately explained in the book, probably because it's not what the book's about. But it nagged me when I was a kid, and it still does now.

All plot holes and paradoxes aside, it's a really good book, and if you have a kid, I recommend it. It's the kind of story that you really can pick apart and look from many angles. In one sense, it's a story about destiny. Tycho and his siblings are all named after extraordinary famous people - Ludwig Beethoven,Tamara Karsavina, Leonardo DaVinci, and Tycho Brahe - in the hopes that they would grow up to emulate them. Tycho's siblings fall into line very easily, adopting the roles that they'd been given from birth. Tycho doesn't - he's interested in a little bit of everything, and isn't entire sure what he wants to do with his life. I knew that feeling when I was eleven years old. Hell, I know that feeling now.

And of course it's about the futility of letting your future control your life. The future isn't fixed. It's an organic, growing thing that you can't begin to control, and the tiniest change in the present could become a radical change in the future. Sure, it's good to have goals and plans, but to try and wield unbending control over who you're going to be is foolish at best.

And that brings me to the nagging question that occurred to me right around chapter 9, the first time Tycho sees his adult self and is terribly disappointed in him. Reading this again as an adult, I found myself wondering that if eleven year-old me suddenly appeared, what would he think? Would he be impressed at the path my life had taken? Would he be disappointed by my physical appearance? Would he be surprised at the relationship I have with my siblings? Would be be shocked that I have a boyfriend? What would his judgment be on his future?

Following right on the heels of that, of course, was the more important question of, "Who cares what eleven year-old me thinks of my life?" Not to disparage the eleven year-olds out there, but you don't know nearly as much as you think you do, and becoming a teenager isn't going to confer any more wisdom. Tycho doesn't know the twenty years of history and context that led to him becoming a miserable bastard. Perhaps if he had learned a little, he might have made better decisions when he returned to his own time. And if eleven year-old me gave me any lip about what I'd become, I'd send him back to his own time with a whole host of new neuroses to deal with.

Anyway, my point is this: The Green Futures of Tycho is a damn fine book. It's a good time travel adventure, and it's a good allegory for the existential angst we all go through when we consider the future. While such feelings might be new and raw to a child of Tycho's age, and old and familiar to us adults, it's still something that we need to deal with. And perhaps that best way to do it is to simply appreciate what we have now.

Review 47: Dirk Gently's Holistic Detective Agency

Dirk Gently's Holistic Detective Agency by Douglas Adams

I want an electric monk.

As Douglas Adams tells us in this book, every civilization creates mechanical devices designed to save us from our labor. We have dishwashers to wash our tedious dishes for us, VCRs to watch those tedious television programs so we don't have to, and finally the Electric Monk to believe in those things we can't be bothered to believe in.

Is that cool, or what?

As strange as it sounds, the Electric Monk is actually integral to the plot. But this plot is complex enough to deserve it. The main character, more or less, is Richard MacDuff, an up-and-coming young computer programmer who has several unique problems. The first problem is that of his couch - it's stuck in the stairwell and, by all logic as affirmed by the best computer modeling systems, should never have gotten where it was in the first place.

The second problem is that he's wanted for the murder of his boss. He didn't do it, of course, but that kind of thing doesn't really impress the police. And, of course, there's the problem with the woman he loves, Susan, who just so happens to be the sister of the boss whom Richard is accused of murdering.

Add into all that the titular Dirk Gently, if that is his real name. Dirk is a man who, since college, has unswayingly, constantly denied having any kind of psychic powers whatsoever - which caused him some problems during his university days when he managed to correctly predict, down the the comma, the contents of a major exam.

Now older and weirder, Dirk runs his Holistic Detective Agency. His work rests on one simple principle: the Fundamental Interconnectedness of All Things. Based on a common misunderstanding of quantum theory, Dirk believes that all things are fundamentally connected to all other things, no matter how tenuous those connections might appear to the unaided eye. So during the course of, say, looking for a lost cat, it is entirely possible that he may have to go down to the beach in Bermuda. Because, fundamentally, all things are connected. And billable.

Then there's the matter of a time machine hidden in Cambridge and the temptation that can arise from having one. With what amounts to a TARDIS, one could go to any point in time and space. You could visit ancient lands, pet extinct animals or, if necessary, fix something that had gone terribly, terribly wrong. It's tricky, but it can be done. And if you're the ghost of an alien whose simple mistake – putting his trust in an Electric Monk, for example – consigned it to billions of years of insubstantial solitude, a time machine might be very tempting indeed.

There's really no good way to summarize this book. As Douglas Adams is fond of doing, there seem to be several plotlines and events which, at first, seem to have no relation to each other. But as you read, you find out that the Electric Monk isn't as funny as we thought he was, that putting a salt shaker into a piece of pottery can cause more problems than you think, and that you should always be afraid of people with nothing to lose.

As Dirk claims, all things in this book are fundamentally interconnected, even if it's not obvious at the moment.

Yes, even the couch.

Review 20: The Doomsday Book

The Doomsday Book by Connie Willis

I honestly can't count the number of times I've read this book. I think this is the fifth time. Or maybe the sixth, I don't know. It doesn't really matter, because it's just as enjoyable, touching and heartbreaking as it was the first time I read it, and that's a hell of an accomplishment.

It is the middle of the 21st century and time travel has finally been worked out. A reliable there-and-back-again way to go into the past and come back to the present. Unfortunately, there are limitations. The computer that makes time travel happen, through means I'm not sure even Ms. Willis understands, will not allow for a paradox. This means if you try to go to the past with anachronistic technology, or carrying a disease that could wreak havoc on the population, the interface simply won't open. If you try to place a traveler somewhere where their appearance could cause a paradox, the machine will put them in another place or time - a factor called "slippage" which can put you anywhere from five minutes and a few feet off your mark to years and miles. The machine won't allow you to get anywhere near events of importance.

Secondly, the machine won't allow you to take anything through the net. So if you travel to, say, Napoleon's palace and try to rob him blind, the interface won't open until you've got rid of all your booty.

Those two factors alone made the time machine economically useless. If you can't profit off it - or change it - what good must it be?

A lot of good, as it turns out, if you're an historian. While the machine may not allow you to get anywhere near Hitler, it will allow you to see what life was like in the ghetto in the 30s. The whole of history suddenly became open to real discovery, and places like Oxford were at the forefront of the research.

One student, a young lady named Kivrin, has a dream to see the Middle Ages. Despite all the warnings that it was full of filth, disease, superstition, danger and death, she still wants to see it more than anything in the world. The sheer force of her will finds her in the machine, ready to go to the year 1320 to see firsthand what life was like for the average English citizen. She has prepared herself as best she could, but nothing could possibly prepare her for the time and place she ends up in....

And in the present, a new plague has spread around Oxford. It's a new type of flu that seems to have come from nowhere, and it's started to kill. Kivrin's teachers and friends have to race the disease, time and sheer bloody-minded bureaucracy to try and find her and bring her back safely.

What is remarkable about the book is the detail. Willis has obviously done a lot of research into not only Medieval Oxford but modern Oxford as well. Since one of the themes of the book is that we don't know nearly as much about the past as we think we do, Willis has gone to great lengths to make sure that we - through the eyes of Kivrin - never know what to expect because our expectations are all totally wrong. And as is so often true about history, the more we know about it, the more interesting it becomes.

The Oxford of the future, by contrast, isn't all that futuristic. It looks a lot like the modern world, probably because it's only a couple of decades removed from us. Sure, there have been advances in technology, but the lives of the people aren't much different from ours.

Interesting note: the book was published in 1992, well before the age of cell phones, instant messaging and the internet. Because of this, one of the greatest hindrances to getting anything done in this far-future Oxford is that no one can get anyone on the phone. It's a videophone, yes, but most of the characters spend time waiting for phone calls to come through or trying to place calls to people who aren't near a terminal. It's a bit strange, from my modern perspective, to see a world that has pretty much conquered disease and mastered time yet never figured out a means of personal communication better than a land-line.

That's just a small thing, though, and as long as you accept that particular bit of alternate-future, you'll be okay. It's a fantastic book, one which I recommend without reservation. The characters are deep and interesting, and the writing really puts you in their world. Seriously. Go get it.
