Review: The Cosmic Landscape

Leonard Suskind is one of the co-inventors of string theory, but this book is not, strictly speaking, an explanation of string theory. Rather, Suskind uses the book as a platform to explain and evangelize the Anthropic Principle as an explanation of why the world we exist is the way it is.

What's wierd about modern physics is that it seems to be exceedingly complicated. Considering that up till the invention of quantum mechanics, all the physics that was known were really short and simple, this is a strange turn of events. Suskind deserves kudos for not attempting to oversimplify string theory, Feynman diagrams, or the strange world of quantum mechanics. In fact, he has one of the best explanations of Feynman diagrams I've read to date. His explanation of the many-worlds interpretation and the megaverse/multiverse is also thorough, fair-minded, and extremely well put. Science Fiction fans will find a lot to enjoy in this book.

Ultimately, though, my recent foray into modern physics is disappointing. There are no deep insights, no grand theories that explain anything. String theory itself makes no predictions:

Throughout this book I have dismissed beauty, uniqueness, and elegance as false mirages. The Laws of Physics (in the sense that I defined them in chapter 1) are neither unique nor elegant. It seems that the world, or our part of it, is a Rube Goldberg machine...

... I often joke that if the best theories are the ones with the minimum number of defining equations and principles, String Theory is by far the best --- no one has ever found even a single defining equation or principle! String Theory gives every indication of being a very elegant mathematical structure with a degree of consistency far beyond any other physical theory. But nobody knows what its defining rules are, nor does anyone know the basic "building blocks" are.

Review: Superman: Secret Identity

I seem to be on a Kurt Busiek binge lately. This little piece was a four part mini series focusing on the life of a Clark Kent who was teased as he was growing up and then discovers to his surprise that he does have the power of Superman. This is, of course, the ultimate adolescent fantasy, and Kurt Busiek is well aware of it and plays on it quite well. His aim, which he discloses in the foreward, was to use Superman as an icon to reflect on the various phases of a man's lifecycle, so he has this Superman age, so he deals with the problems of being an adult, becoming a father, having children, and then faced with losing his powers as he ages.

Overall, the topics are handled quite well, and the book is a good read, but rather lightweight. The topics are breezed through rather cursorily, though the art is gorgeous and lovely to look at. Recommended, but not nearly as insightful as Alan Moore's Miracleman. Read that first, if you can get a hold of it.

2006 Book Reviews

If you're just looking for reading materials, I've recently posted the 2006 books of the year.

Fiction
Non-fiction
Graphic Novels (aka Comic Books)

Review: The Algebraist, Iain M. Banks

Banks is not exactly a hard science fiction writer, even though his novels have a veneer of it. Typically, he leaves the hard science exposition really empty (unlike Stephen Baxter) and concentrates on the characters. In this book, however, he plays a joke on long time readers of his, and writes a book that is more mystery than science fiction or character exposition.

The main plot revolves around Fassin, a delver, a member of a class of scholars who have been privileged to interact directly or through telemetry with the denizens of his local system's gas giant, creatures who call themselves Dwellers. The Dwellers are a really long-lived species, dating back several billion years, but seem to have dropped themselves out of interacting with other species that they call "The Quick".

Several hundred years ago,Fassin accidentally discovered a piece of Dweller text that implies that the Dwellers have a secret wormhole network that permeates most star systems in the galaxy, and when word of that leaked out a war was started. Now Fassin must once again delve into the local gas giant and find the secret key to the wormhole network before invaders take over his home. The mystery to be solved by the reader is the nature of the wormhole network and what the key is. Clues are scattered throughout the novel, which has the structure of a repeated quest.

Distractions are provided through descriptions of a number of Fassin's friends and their relationship to him. This piece of misdirection worked incredibly well --- for instance, Banks spends page after page building up a particularly dastardly villain, only to dispatch him in less than a paragraph near the end of the book, which meant that I didn't concentrate on the mystery at all. There's no physics knowledge or higher mathematics needed to solve the mystery --- all the bits are provided there right in the book for you.

My only complain about the book, then, is that Banks needed to say, "Mystery! Mystery!" all over the frontipiece of the book instead of "Science Fiction!" Recommended, but I would not buy the hardback.

Rebalancing a Portfolio is hard...

So I finally sat down and systematically rebalanced my portfolio. From when I started to when I finished was about one and a half hours. My primary tools were Vanguard's web-site and Excel (any spreadsheet will do, but when you copy and paste a table from a web browser into Excel, it does the right thing and numbers stay numbers, which is very important for fast imports).

Vanguard offers a unified account consolidation view (including all your bank accounts, savings accounts etc), so when I selected and pasted that into Excel, I got all my financial data in one easy place (I don't trust my quicken accounts, since it's not completely up to date). I then create a table with my ideal asset allocation (I use the table provided at The Retire Early Home Page to set up my allocations).

After that, it's a matter of systematically assigning allocations to my existing investments, and adding up all my assets. (Don't forget to subtract your liabilities!) Then you figure out how far each asset class deviates from your ideal, and rebalance. In my case, there were a few items I didn't want to touch, so I over-rode my ideal allocation and went with something less than ideal (isn't that life?). For each asset class, you might want to sub-divide the allocation. (For instance, for domestic stocks, you might want to divide into small cap/mid cap/large cap, or for maximum convenience just use a "Total Stock Market Index")

Then another visit to the Vanguard web-site to perform the asset re-allocation.

A few things to watch out for:
  1. When allocating assets, if possible move stuff around in retirement accounts for the rebalancing. That allows your rebalancing to be tax-free to the largest extent possible.
  2. Consider the size of the re-allocation. If it's large enough, ETFs might make more sense than index funds. If it's too small, then mutual funds are more efficient.
  3. If you're going to take a loss from a re-allocation, depending on your circumstance, it might make sense to try to make it a long term loss rather than a short term loss, or vice-versa. (one tax management trick I've done in the past is to harvest a loss by exchanging one fund for another fund of the same asset class, thus staying invested while getting a capital loss for tax purposes --- but obviously, that's not as good as having lots of capital gains everywhere in your portfolio!) Note that such tax tricks are better off done closer to the end of the year when your overall tax picture is closer.
  4. Your tax situation should only dictate which particular vehicles you want to use for your asset classes, not which asset classes you want to be in.
How often should you rebalance? Well, if you're David Swensen managing the Yale endowment portfolio, every day! If you're the typical individual investor, then once a year is what's typically recommended. Of course, your circumstances can vary!

Interestingly enough, if Vanguard is your employer's 401(k) manager, the on-line tool gives you a one-button rebalancing option (it rebalances to your 401(k) new money allocation, which is what you want if the 401(k) is your primary investment asset). That's very nice, but can't take into account your overall financial situation. Nevertheless, for those whose primary investment assets are in their 401(k) and are lucky enough to have Vanguard as the 401(k) trustee, it's a very nice button. Just push it and you're done! No spread-sheets, no tax consequences, and no hard thinking.

Trouble comes in threes

On Sunday, my network hard drive (a Ximeta NetDisk) died a horrible death, taking all the data on it with it. And of course, I did not have an adequate backup plan. So off to Fry's again, where I bought a replacement IDE drive for the Ximeta enclosure (which was fine and serves quite well) and an external USB drive to back up the Ximeta disk.

Then today, my laptop hard drive died. Fortunately, it's a corporate machine so it's backed up by IT (I think!).

Finally, on my way home, I got a flat. Let's hope that's the end of my troubles this time.

Review: Hiding in the Mirror

Laurence Krauss wrote The Physics of Star Trek, which despite its lightweight nature, was good reading and accurate. This book, a non-technical treatise on string theory and superstring theory, is a good enough book for someone with very little understanding of Physics or Mathematics, but unfortunately, string theory and all of its variations are such a complex subject that I barely gained an understanding of what it was by the end of the book.

The first half of the book is about dimensionality, which includes one of the best explanations of Einstein's theory of relativity in layman's form that I have read. This part is easy going and a good refresher even for those of us who've covered the material before. The second half bogs down in attempts to explain Mathematical concepts in English, which of course is very hard, especially since string theory appears to be an entirely mathematical concept --- there has not been any successful attempts to prove it correct or wrong, which means that the theory has made no useful predictions. Of course, that doesn't mean it's not elegant mathematics, but it does mean that it's an incomplete story. I hope Krauss is around to explain the story when the Physicists finally figure it out one way or another.

Snow on Serra Azul

It was supposed to be snow at 500' on the night of the 12th, so Lisa & I hiked up to see it! It was pretty warm as we hiked, with rain coming down, so we expected to be disappointed, but indeed there was plenty of snow! Posted by Picasa

Saturday's Ride

It had snowed the day before, so Roberto Peon, Mike Samuel and I decided to go see if we could see some up close on Diablo. Roberto, in particular, had acquired a nice carbon Fuji and wanted to see how it would do on some substantial climbs. There was some confusion with the meeting point and I had an inexplicable flat front tire in the parking lot at Diablo Vista Park, but with everything ready we got rolling by 10:30.

The ride to the South entrance if Diablo State Park was enough to get us warmed up, and the climb up Mt. Diablo Scenic Drive soon led us to glorious vistas of the area below: San Ramon and its environs. The day was clear and there was very little mist in the air. To my chagrin I realized that in all the excitement to get going I had left my camera at home! We saw a bit of snow near the peaks, but it didn’t look like it was completely covered in snow. We rode along at a good clip, and as we passed the entrance station we saw a sign that said the road was closed at the Juniper campground.

At the junction, we stopped and rested and ate a little bit before turning right and up towards the summit. Traffic was quite heavy, probably because there were others with the same ideas we had, but wanted to drive up as far as they could. In 2 miles we arrived at the Juniper campground and sure enough, it was closed. The road closed sign was evidently traversable by bicycle but with 2 rangers watching me I did not feel like blatantly ignoring the sign, so we refilled out water-bottles, put on and started rolling down the hill. As I got near the junction road, I saw a steep path leading off from the main road and two men climbing it, one wearing suspenders. I knew it had to be none other than Grant Petersen, so I shouted out his name and rolled up the path.

Grant stopped and I introduced my companions. He was test riding the new 650B tires (I forgot the name: Lumpy Frumpy?), and they definitely looked hefty enough for serious trail riding, with a dimpled tread pattern. We chatted a bit and he asked me why I wasn’t at the handmade bike show in San Jose. I had forgotten all about that show, but in any case would rather be riding bikes than looking at them. I mentioned that we were going to ride Morgan Territory road, and Grant’s companion said, “Good for you!” in a tone of voice that made Roberto and Mike say, “Great. Now we know we’re in for it!” I told Grant about the road closure, and he said that the rangers wouldn’t have fined us even if we had made an illegal run up the mountain. Oh well. I asked Roberto and Mike if they felt like going back up there, and the consensus seemed to be that we had plenty more climbing ahead of us, so we said goodbye to the Rivendellers and headed down the hill.

Roberto had great fun with his new bike on the descent, and proclaimed it excellent as he rolled and rolled up and down some of the rollers. Soon enough we were in Walnut Creek and made the right turn onto the Contra-Costa County bike trail, which we took over to Treat Blvd and Turtle Creek road. As we approached the town of Clayton, Roberto got a front flat, and discovered a torn in his tire. He took a look at the inner tube of his front wheel and decided that the rubber was so thin that it was just looking for an excuse to puncture, so he put in a new one and threw away the other.

Soon enough, we were in Clayton where we had lunch outside at the Grill. Around us I could see clouds start to gather as the temperature dropped. After a too-heavy-for-me lunch, we started down Marsh Creek road again, which made its way up a hill to get over to the ridge where Morgan Territory road started. I definitely felt the lunch work its way into my stomach, so perhaps Marsh Creek road wasn’t surprisingly steep. Having climbed it on a tandem only, I didn’t think it would be as painful on a single, but apparently it’s not the road, it must always have been the excess food in my stomach.

Traffic on Marsh Creek road was heavy, and it was a relief when the descent started and led us at the bottom to Morgan Territory road where we could relax and breath for a bit. Morgan Territory road starts out as being a few farms and houses and then plunges down to alongside a creek and turned into a road that was narrow (single-lane only), rough, and debris-laden. Nevertheless, the sound of the creek was lovely (I had never seen it so full), and the road as pleasant to ride as ever.

We rolled along a little bit at a gentle pace but soon enough, Roberto felt a bit of vim in started turning up the speed. It took everything I had to stay with him, but as he turned a steep corner I dug down and found nothing, so decided to let him go ahead. After a few corners I saw him again, but he had just passed a truck parked alongside the road and the driver was shooting pictures, so I posed a bit. As I passed I asked him if the camera was digital and he said “yes.” So I turned around and went back to him to provide an e-mail address so he could e-mail me photos. We chatted a bit and he mentioned that Mike was a distance behind me, but I had no doubt he would catch up. I took my leave of Brian Daniels and went after Roberto with little motivation.

It didn’t take long, however, before I spotted him waiting at the entrance to the Morgan Territory Regional Preserve parking lot. He told me he waited for 4 or 5 minutes and looked very happy. It didn’t take long before Mike showed up. “We’re not far from the top now, and we’ll stop there to put on clothes.” “Is it a bad descent?” “No, it’s straight and long, but the feeling of falling out of the sky always makes me nervous.”

What I was unprepared for, however, was the views. The wind had swept away all clouds while we were climbing, and we could see as far as the windmills of Livermore and the Bay. It looked stunning by the light of the mid-afternoon sun, and I wished I had brought my camera. The descent along the twisty road with lots of blind corners and a single lane wasn’t excessively fast, but had a dreamy, flight-like quality along the smooth road with very little wind. Roberto took off like a rocket as soon as the road started developing rollers, and Mike said to me, “You’ve created a monster.” “Indeed, on his new bike, he climbs fast, descends fast, and rolls fast on the flat!”

We regrouped at the bottom of Morgan Territory road, turned onto Manning and Highland roads, and rolled the remaining miles through beautiful pastoral country side with light coming through partly cloudy skies. All in all, it was a great ride with 63 miles and about 5000’ of climbing.

Ok, now I need a gtags intern

I previously mentioned that I already had a summer intern for 2006. Well, my intern accepted a full-time offer at Google, so now she's not going to be my intern but will be a colleague instead (yay!). Which leaves me still wanting an intern for gtags for summer 2006. If you're interested in working on gtags, please send me e-mail (or post in the comments with contact information). If you've already submitted your resume through the google intern application process, please just note your name and I'll work the internal system and try to schedule you for an interview. (No promises: if your resume doesn't look good to me, then you won't get an interview or call back)

Review: Local Heroes, Kurt Busiek

Kurt Busiek's Astro City is a post-modernist take on super-heroes, the quintessential American mythos. He relies very much on your latent knowledge of super-heroes, and populates Astro City with clones and derivatives of them --- the Superman clone, the Batman identico, the speedster, and all the correspondent types. His approach is unique in that he does not discuss their abilities and their origins (except in one case, and that was only to provide an interesting perspective on his version of Batman). Instead, he takes the oblique view, providing a look at the heroes from a small, limited perspective.

This collection starts off with the point of view of a doorman at a local hotel, and then rapidly cycles through a host of ordinary people, including a comic book writer, a retired hero, an attorney, a ex-superhero's girlfriend, and a young girl who leaves Astro City for the first time to visit her countryside relatives. Each of the stories come with a little twist, and each tale revolves somehow around a superhero, but from the perspective of an ordinary person. The art is well done and consistent.

Overall, the series and the book is recommended. Kurt Busiek is no Alan Moore in the early nineties, but he is the equal to Moore's current series of books.

Review: What's the Matter with Kansas

This book was all over the political press last year, and frequently cited as a good explanation of why the Democrats keep losing election despite having a much better platform, much better track record of governing, and much more palatable policies.

Written in a style that's sarcastic (that's "witty" for some people), and not without more than a little bitterness, Thomas Frank first provides a short synopsis of Kansas history. Kansas in the 1890s was a bastion of left-winged politicians and reliably Democratic. The shift to conservatism, Frank writes, mostly occured in the 80s and 90s, and is driven largely by culture warriors, not economics.

Franks provides a history of the religious radical right and its seeds in the anti-abortion movement, which was quickly seized upon as a platform to build a far right largely oriented around cultural issues while mostly centered around (in policy) tax cuts for the rich. He interviews interesting folks such as Kay O'Connor, who is not your typical fat-cat Republican, but a relatively low-income person who wishes to "turn back the clock" on cultural issues:

"I'm a happy captive of forty-three years," she tells me, "and I am obedient to my husband in all things moral."

On economic issues, O'Connor says:

"Why should we be penalizing people for being financially successful?" she asks. "When you take from the rich and give to the poor, that really is Robin Hood, and that's just theft. Robin Hood was a thief."

Franks explains that the culture wars can never really be won by the right, since political victories can't do much to change culture (which is largely provided by the entertainment industry), and so these repeated failures to win the culture wars keep the right extremely riled up, despite winning all three branches of the government. It's difficult, for instance, to push creationism in public school, but each loss in the courts only serves to spur the religious right into another frenzy of political activity.

It is only in the epilogue that Franks comes down on the Democrats:

The Democratic Leadership Council (DLC), the organization that produced such figures as Bill Clinton, Al Gore, Joe Lieberman, and Terry McAuliffe, has long been pushing the party to forget blue-collar voters and concentrate instead on recruiting affluent, white-collar professionals who are liberal on social issues... As for the working-class voters who were until recently the party's very backbone, the DLC figures they will have nowhere else to go... Besides, what politician in this sucvess-worshiping country really wants to be the voice of poor people? Where's the soft money in that?

To a large extent he is over-simplifying the issue. Bill Clinton's economic policies were by and large, well-informed, and served the poor well, despite also being good for the wealthy. Free trade does do a lot of good for the poor, despite a lot of hand-wringing from the left. Having said that, I understand where Franks is coming from. In a political environment where the losers from free trade feel enormous hardship without wage insurance or other mitigating factors, I cannot imagine a blue collar worker who cares about his self-interest voting for a free-trading Democrat. To my mind, the charge that "there's no difference between the Democrats and the Republicans" stem largely from the free trade agreements that have been signed by both parties when they were in power without any mitigating policies to help protect the losers whatsoever.

I'm a believer in free trade and its ability to not just help the poor in the US, but the poor in all parts of the world as well. But if you asked me to choose between fiscal responsibility, protecting the environment, providing a reasonable social safety net and a national healthcare system that works and free trade, I'm happy to flush free trade down the toilet any time. The big mistake that the Democrats have made is not realizing that political tradeoff, and with the large decline in labor union, it may never recover. While Clinton's policies were very sane, I think that a largely uneducated population that gets all its news from TV (and Fox News) will never be able to understand why his policies worked as well as they did (yes, he was lucky, but he also had policies that capitalized on his luck), and will only remember him for his relationship with a certain intern.

But the alternative, that the right-wing Republicans capture power for all time is even more scary. A USA where the schools teach creationism isn't going to be fun, even if you're rich. Laws that revoke women's right to votes, ban women from the workplace will make America a poorer place, in spirit and in reality. Research will grind to a halt, and the innovation spurts we are used to seeing will be gone. Fortunately, there will be a backlash before it goes that far (I hope).

In the mean time, I think (as Franks wrote) that I can find it in myself to enjoy the deep tax cuts for the well-to-do that the religious right has forced down my throat to the detriment of themselves and their children.

Figure skating: Sport or Art?

Dan Engber complains that figure skating has become a video game:
Here's how the new scoring system works: A technical specialist identifies each move that a skater performs, and assigns to it a level of difficulty. Then the judges rate each of those moves with a "grade of execution." To compute a skater's total score, get out your "scale of value" chart and cross-reference the move, its level, and its grade. For example, you'd get 7.5 points for completing a basic triple axel. A perfect triple axel earns a couple more points, and a lousy one a couple fewer.

With such explicit scoring rules, skaters have learned to pad their numbers. A brief look at the chart reveals that a string of fancy moves done badly is worth a whole lot more than a string of simple moves done with grace and élan. What about tumbling on your ass? According to the rules, a fall on a jump automatically gets you the lowest grade. (Every fall also earns you a one-point deduction.) But if the jump is fancy enough, that low grade will still be worth big points...

There are required elements, of course, and limits to the number of jumps you're allowed to attempt. But skaters who know the system can treat it like a video game, stringing together fancy combos so they can rack up a high score.

And you know what, I actually think that's a feature! I don't watch figure skating myself (no TV, and no real interest, thank you very much), but to me, that's the difference between sport and art. Art should be flawless and look good, but sport should be about atheleticism, ability to perform on the event, with bounded rules and as much as possible, no subjective judgement necessary.

In a running race, nobody scores points for style --- it's whoever crosses the finish line first, even if he was the ugliest person since Humphrey Bogart. If figure skating wants to be an Olympic sport, it shouldn't be any different otherwise, it's not a sport, and should be thrown out of the Olympics. I don't understand why anyone should complain about the new rules for figure skating. To my mind, if the rules don't encourage risk-taking and achievement of the hardest possible jumps and stunts, then the rules would not be congruent with the spirit of the Olympics.

Review: Shock Rockets

Kurt Busiek first came to my attention through his conception of Astro City, a neo-superhero world that takes a respectful view of the super-hero genre while providing a fresh take on it. (His "Batman" character, for instance, has a secret that was both original and interesting)

Shock Rockets is his attempt at juvenile science fiction, similar to John Varley's Red Thunder. It features a world where Earth survives an alien assault by stealing enough alien fighter planes to turn the tide. Only 6 of those planes survive the war, and are now used to maintain peace in the post-invasion world.

The story starts with a disenchanted kid who accidentally ends up piloting one of the rockets when the pilot dies (with only the slightest tip of the hat to Abin-Sur handing over his ring to Hal Jordan). He then starts to discover that the ships and his world aren't quite what they seem to be on the surface.

The story deals with many interesting social themes, from class resentment to team integration. The slow reveal of the story behind the ships and the world behind the story is also skillfully done, and the art is excellent. The end of this volume provides a plot revelation that obviously leaves plenty of room for sequels, which I hope will be as interesting as this first book.

Recommended.

Review: Akira

I saw Akira the movie several years ago, and it felt like a movie made from a book --- the movie didn't quite make sense, despite the technical virtuosity behind it (the voices from the child actors were recorded first, then the animation drawn to match the voices). It reminded me quite a bit of 2001: A Space Odyssey, a movie that did not make sense to me until I read the Arthur C. Clarke novelization (which apparently was written while the movie was filmed).

So when I went to the source, I hoped that it would be coherent and sophisticated. Unfortunately, it seemed that while the movie did not encompass all the plot points (the romance beteen Kaneda and Kei was removed with the character of Kei being eliminated from the movie, for instance), it held true to the spirit of the manga --- lots of explosions, an inexplicable plot, with no "science" whatsoever behind the fiction. The ending was unsatisfying as well.

All in all, not recommended.

President's Day Ride

I wanted to see if there was any snow left on Skyline, two days after a once a decade snowfall in the Bay Area. I climbed Pierce Road and Highway 9 with no trouble, seeing no other cyclists except a mountain biker on Pierce Road who turned off towards the reservoir. The amount of car traffic was considerable, however, indicating that many folks had the same idea I did. The weather was warm, prompting thoughts that the snow might all be gone already.

A left turn on Skyline Blvd brought further climbing and the temperature rapidly dropped under the shade of pine trees. I stopped at an open space to check out the visibility --- unfortunately, it was not clear to the coast --- a light haze filled the air and I could not see the Big Sur coastline hidden in the clouds.

As I approached Castle Rock State Park, I started seeing patches of residual ice on the roadside. The road surface became sandy and grimy and quite wet. As I approached Castle Rock, I observed that the parking lot was full. Sure enough, there were kids throwing snowballs at each other! The tree branches above me were still laden with snow, the melting of which caused droplets of water to fall on the road (and on me). There was a crackling in the air as pieces of ice broke off from the snow clumps and landed onto the road. I stopped for a couple of pictures and then moved on.

Past Castle Rock, the road began a rapid descent, but out of the corner of my eye, I could see that the Christmas Tree farm along Skyline was inundated with snow in its open spots. The descent on Skyline is normally enjoyable and fast, but with the road surface dark and wet, I did not want to risk running over any black-ice and kept my speed down. About a mile from the Black road intersection all traces of ice and snow went away and I could relax again and enjoy the open scenery all around me.

Past Black road, Skyline Blvd becomes a one lane road that has relatively light traffic but many blind corners, which I took prudently despite the lack of motor-traffic since Castle Rock. The reason for this lack of traffic became apparently when I ran up to a "Road Closed" sign. It looked like a minor bit of construction, so I walked my bike around the sign and through the construction. The construction was muddy, and some small stones got wedged in between my brakes and the rim, but a bit of extra water and a stick used as a scraper solved that problem.

Except for an unusual amount of traffic down Bear Creek road, the rest of the ride was uneventful.

Snow on Skyline Blvd

2 days after it snowed, there's still some residual snow in trees on Skyline Blvd near Castle Rock State Park. It was cold, with crackling sounds filling the air as the clumps of snow disintegrated as it melted, dropping pieces of ice onto the road. The road was moist and gritty with all the dirt stuck to the pieces of snow, but there wasn't any ice. Posted by Picasa

Einstein's Dreams

This is a cute little short book about time. It's a novella full of little montages about alternate realities where time is somehow different. People who know a little bit about the Theory of Relativity will understand the references to special circumstances where time does behave differently, even in our universe (near a large gravity well, at high velocity, etc), but those are merely references, not allegories.

The writing style is light, almost whimsical, and the chapters short and easy to read:

In this world, it is instantly obvious that something is odd. No houses can be seen in the valleys or plains. Everyone lives in the mountains.

At some time in the past, scientists discovered that time flows more sloowly the farther from the center of the earth. The effect is minuscule, but it can be measured with extremely sensitive instruments. Once the phenomenon was known, a few people, anxious to stay young, moved to the mountains. Now all houses are built on Dom, the Matterhorn, Monte Rosa, and other high ground. It is impossible to sell living quarters elsewhere...


This book is recommended as a light read.

Ammonite, by Nicola Griffith

This book is not science fiction. First of all, a virus that kills all the men and only 20% of the women is scientifically implausible. That the same virus might give all surivors access to a collective Jungian unconscious is even more implausible. The last straw came when I read the author's afterword at the end of the book:

Women are not aliens. Take away men and we do not automatically lose our fire and intelligence and sex drive...


As far as I could tell, only aliens could have lived on the planet that Griffith describes: there's no easily accessible medical technology, yet every woman survives childbirth. The "men's world" of technology (referred to as The Company)is equally implausible --- despite great scientific advances (ability to manipulate DNA that can create a vaccine without access to an actual viral sample), they are unable to disinfect returnees or provide advanced medical help better than a splint?

As a fantasy, this book fails as well. The protagonist does boneheaded things that in any sane world would have resulted in death or worse. She makes decisions that binds her cohorts and colleagues without consulting them, and then expects them to agree to be bound by them, and in general behaves like a total dick.

All in all, that such a book won the Tiptree Award while David Brin's Glory Season was denied it will lead me to ignore the Tiptree Award in the future as a possible signal for the goodness of a novel. Brin's comments as such appear as a text file here. Download by using "save as" and view using emacs.

The Merchant Princes Trilogy (parts 1 & 2)

I seem to be reading a lot of Charles Stross lately, and complaining that I didn't like his character development. I also have to stop reading book series where the entire series haven't been published yet (George R. R. Martin, I'm looking at you).

That said, The Family Trade and The Hidden Family demonstrate significant improvements over his earlier works. Stross openly acknowledges his inspiration by Roger Zelazny's Amber Chronicles, which feature a family of world-walkers, people who can travel between parallel Earths through the use of a pattern.

Stross does Zelazny one step better, however, by extrapolating what would happen if a family which didn't have supernatural powers actually did exist, and set out to exploit this ability to gain secular power and wealth. He uses the trick of having the heroine of the story be someone who was unaware of her family's existence stumbling into her heritage as a Duchess, and executed a very well-done play on the "adopted princess" fantasy trope, complete with the "princess" realizing that being stuck in a medieval world just isn't very much fun.

The action in the novels move fast and furiously, with little pieces of exposition thrown in that aren't too awkward. The heroine, unlike many fantasy heroines, isn't one of those people whom you just want to grab by the scruff of their collars and shake, is sensible and intelligent, and does what a smart, well-educated person would do in her position (she's just a little bit tougher than your average person, but not any more unbelievable than Veronica Mars was).

Once the action starts, I found the books hard to put down, and to be fair to Stross, even though its a trilogy, you won't come to the end of the second book feeling cheated even though the ending is yet to be written.

Recommended.

Review: Coraline

Scarlet considers this one of her two best books of 2005, so I checked it out of the library and read it. It's not a bad book by any means, but I don't think it's anything special. It's definitely not even in the same class as StarDust, which I consider to be the best of Gaiman's prose works (by the way, buy the one with Charles Vess illustrations, which is the way the book was published --- the "words only" version are for snotty people who don't think that comic books can't be considered literature).

The horror I find to be rather pedestrian, but then again, I don't think I was ever the kind of kid (or now, adult) who could be horrified or scared by words on a page --- visual horror can terrify me, but not novels or books. The real horror in the book, for me, is the portrait of a child thoroughly neglected by her parents. I guess I can be grateful that my parents always found time to play with me, and gave me such imaginative tools and toys in my mind that I was never ever bored, either as an adult or as a child.

Anyway, it's a short book, so it's not a waste of time.

Two interesting articles in this week's New Yorker

First, there's a Book Review of The Man Who Knew Too Much, a biography of Alan Turing that doesn't sound like it's worth reading. However, the review provides a nice, condensed summary of Turing's life that's very much worth reading. The definitive book on Turing is Alan Turing: Enigma, which I read a while ago and remember as being quite good.

The second great article is an article by Malcolm Gladwell about Profiling. It busts the typical myths about profiling, and uses excellent journalistic technique to illustrate his point. I subscribed to The New Yorker on the basis of Gladwell's visit to Google, and if only every issue was like this one I'd feel like I got my money's worth.

Of course, what annoys me is that we don't have a magazine even half as good as The New Yorker here in the Bay Area. We get crappy stuff like Gentry Magazine, a magazine for people who worship wealth and its privileges, and Sunset Magazine, a vapid lifestyle magazine with no depth. Ah well. In exchange we get good weather and a fabulous outdoor life. Now, if only my copy of the Rivendell Reader would just show up! Now that's a magazine I'm proud to have contributed to, and one that could only exist in the San Francisco Bay Area.

Review: Singularity Sky

This was Charles Stross's first novel. An information war is being waged on Rochard's World, a colony of the New Republic, an authoritarian regime. The regime's response is typically militaristic, but two representative of external agencies attempt to intervene, resulting in a spy story set in a science fiction universe where time travel is possible. Stross was a computer scientist, so at least he attempts to get his physics right, and make references to John Conway's Game of Life, which a lot of software engineers and mathematicians are familiar with.

The characters, alas, are not very developed, and one gets the idea that they exist for the sole purpose of the plot, rather than being real people you could meet and like. In this, at least, Stross has the same problems as other hard science writers like Greg Egan and Stephen Baxter. Just because you're a real scientist/mathematician of some sort doesn't guarantee poor characters, as Vernor Vinge aptly demonstrates.

The sequel to this novel is Iron Sunrise.
