Fun little math problem

Monday, May 17th, 2010

I love math and logic puzzles that seem like they could require a lot of thinking but turn out to be answerable in 30 seconds if you think about them the right way. Here’s one Jake Wildstrom recently posed that I liked:

Take a random permutation of the n integers from 1 to n. On average (that is, we’re asking for the mean), how many elements will be in their “correct positions” (e.g,. 3 in the third slot)?

2010 US Chess Championship

Saturday, May 15th, 2010

This year’s US Chess Championship is currently being played in Saint Louis; it started yesterday and runs through May 24. The reason I bring it up here is that I think that the organizers are doing a good job of making it accessible and interesting for casual chess players, one of which may be you. The live coverage in particular is very nice; it’s hosted by Grandmaster Maurice Ashley and Woman Grandmaster (don’t get me started on that title) Jennifer Shahade, who are both really good at making the game exciting for people who are already a little interested in chess. They’re not trying to “jazz it up” for people who don’t care at chess at all; they assume you already know a bit about the game and are inherently excited by, say, someone sacrificing a rook for a knight, or pushing a pawn closer to queening.

There are also a bunch of different types of players, ranging in age from 15 to 50+, with a variety of personalities and styles, so it’s not hard to find someone to root for if you like that sort of thing. If you already have a casual interest in chess but don’t know much about high-level tournament play, I recommend checking it out and seeing if it grabs you. (If you don’t, never mind this post!) The games run about 2pm-8pm Central Time every day.

Hilary Mantel: Wolf Hall

Saturday, May 15th, 2010

This novel takes the all-too-familiar career of Thomas Cromwell and turns it inside out, revealing an unexpectedly thoughtful and empathetic character. What’s that, you’re not familiar at all with the career of Thomas Cromwell? Well, neither was I, and I suspect that that made my reading of it much different from the intended one, as I ended up reading it purely as a historical novel and not as some great reimagining. But it was a really good historical novel.

Thomas Cromwell was born a commoner and rose to become one of the must trusted advisors to Henry VIII (the one with the six wives — we just get the first two of them here). He seems to be regarded by history mostly as a villain, largely based on his standing as the chief nemesis of Thomas More, who opposed the king’s declaring himself the head of the church. Mantel turns Cromwell into a real person, who is not perfect but is generally always trying to do the right thing.

Her writing style here is intriguing; it’s very restrained, avoiding much emotion or florid description, and you get the feeling that it is meant to reflect Cromwell’s own character. Cromwell himself, although present in every scene (as far as I can remember), is hardly ever mentioned explicitly by name, but is just called “he” unless it is really necessary to distinguish him from another man in the scene. There is pretty much no “As you know, Bob” exposition; the characters talk to each other as if they already know the subject they’re discussing, which can make it a little hard for the reader to catch up, but is rewarding once you do, making it feel a bit like you’re in on a secret.

The plot moves fairly slowly, and I think I might have been happier with it at 400 pages instead of 550, but it remained very interesting all the way through. I imagine that part of the slowness for me was that Mantel wanted to visit and reinterpret a number of important historical incidents, none of which meant much to me.

So I feel like I didn’t get everything out of it that the author put in; it’s sort of like hearing a cover of a song without knowing the original and thus not being able to hear what original aspects of the song the new performer kept or discarded or reworked. If you are already familiar with 16th century English history this book is probably revelatory (and in fact it has won all sorts of prizes); if you’re not, it’s still an excellent read.

Cardiacs: musical vocabulary

Sunday, May 9th, 2010

It’s been a while since I first posted about Cardiacs but I’ve been fitfully taking some notes and doing some transcribing, and I should post some of it before I forget about it entirely. If I list a song here without a video link you can probably find it in the previous post.

Although a lot of the music of Tim Smith (leader and main songwriter of Cardiacs) might seem pretty random, he has a pretty consistent vocabulary that makes it easier to get a handle on his songs after you’ve heard a few of them. Going through his oeuvre, here are the things that stand out to me:

Melodic movement by whole tones. One common consequence is the use of chord sequences involving I, ♭VII, and ♭VI (think “All Along the Watchtower” for one classic example). Even more common is the next item:

Use of the Lydian scale. That’s a scale on the white notes if you start on F. Its distinguishing characteristic is that it starts with three whole-tone steps (F-G-A-B) rather than two whole-tone steps followed by a semitone (F-G-A-B♭). Smith really loves that sharp fourth and it shows up all over the place in his music.

v – I and ♭III – v – I cadences. These are sort of related to whole-tone melodic movement as well. If you play a normal V – I cadence (say, B major to E major) but use a flatted seventh instead of a leading tone (D♮ instead of D♯ in this case), so that you’re moving by a whole step instead of a semitone to get to the tonic note, you get a v – I cadence instead (B minor to E major), which has a much more ambiguous quality. In Cardiacs songs, this frequently comes in the context of the progression ♭III – v – I (e.g., G – Bm – E), which has quite an unstable feel. Often the ♭III has been heavily tonicized, which can make the sudden shift feel like the rug is being pulled out from under you; when repeated, it can also create the impression of shifting back and forth between two tonics, never fully coming to rest on one or the other. “Odd Even”, for example, is fundamentally based on a G – Bm – E progression, and it’s hard to decide whether to take G or E as the key of the song. The coda of “Dirty Boy” is another classic example that just repeats this progression over and over.

Quick-changing chords, often every other beat and accompanied by their dominants. The harmonies can often move at a dizzying pace, but because Smith usually precedes or follows a chord with one a fifth away, you get a little more stability and each chord at least has a bit of context to it. “Anything I Can’t Eat” is a classic example (sorry about the bad recording).

Hemiolas and other rhythmic ambiguity. A hemiola is when you take a six-beat-long phrase and go back and forth between treating it as two groups of three and three groups of two, creating a sort of rhythmic pun that throws the listener off. Smith uses explicit hemiolas (“Gibber and Twitch” and “Too Many Irons in the Fire” both switch from 3/4 to 6/8 mid-chorus) but is also happy to use any other technique he can to disturb the perceived meter of the song.

Tempo shifts, particularly a slow last chorus. It’s astonishing how effective this is, given its relative crudity — just shift down a gear entering the final chorus and have everybody sing along, and the majesty of the song doubles. There are probably ten Cardiacs songs that do this, though it never seems to get old; the classic example to me is “Big Ship”.

I am probably the first person to ever compare Tim Smith to the classical composer Olivier Messiaen, but one thing they do have in common is a very personal musical vocabulary (in Messaien’s case, it’s things like birdsong and harmonies built on top of palindromic modes). In both cases, initial experiences can be rather befuddling, but once you start hearing the common building blocks from piece to piece, the broader context helps in making sense of each one.

Next up, a case study of one Cardiacs song.

Sergio de la Pava: A Naked Singularity

Wednesday, April 7th, 2010

A couple of months ago I got a random email saying (paraphrased) “Love your Infinite Jest notes, love your blog, can I send you a free copy of this novel that appeals to a lot of the people who like Infinite Jest?” I looked it up and saw that it was self-published, which is not a great sign, but a few pages on the net did praise it effusively, and I figured that there was no downside, so I said sure. I wasn’t planning to read it any time soon, but a few weeks ago I picked it up and read a few pages, and then read a few more, and then I read the whole book, and damned if it wasn’t really good.

The novel is A Naked Singularity, and it is a big mess, but luckily for de la Pava, I love big messes. Infinite Jest itself, Gravity’s Rainbow, Sandinista!, Zen Arcade — if it’s some gigantic work that overflows its banks and doesn’t know when to stop, chances are good that I’ll love it.  It’s a 700 page book, but we’re at about page 300 before the plot even really gets started; most of the beginning of the book is filled with a depiction of what it’s like to be a public defender, as the narrator is, in between a bunch of entertainingly digressive dialogues dealing with subjects ranging from abstruse philosophy to pop culture.

Actually, once the plot really gets started and the book gets more focused, it gets a little less interesting and more conventional, but it never stops being entertaining. Most readers would likely disagree, but I almost wish that the novel was even more of a big mess. It’s already 700 pages; why not add a couple hundred more and keep the second half of the book as crazy as the first?

Back to the good points about the book. As I said, the writing style itself is super entertaining. For example, even though about 5% of the the book is taken up by the narrator going on about the professional boxing scene of the 1980s, I didn’t mind. And learning about the life of a public defender was very educational, and naturally enraging as well. There were a bunch of interesting stylistic experiments (there’s one great chapter in particular that keeps jump-cutting back and forth between different scenes during one day) which I would have been happy to see de la Pava take even farther.

A Naked Singularity is self-published but it’s not that easy to tell; the physical book and its layout are very professional, and the only thing giving it away to me was a larger-than-usual incidence of typos. I’ve seen other reviewers wish that it had been edited down some, but as I said earlier, I kind of wish it had been edited even less. I don’t know how hard de la Pava looked for a publisher — it seems hard to believe that no one would have taken a chance on this being the breakout hit of the year. Hopefully his next book will find a wider audience. I’ll certainly read it.

P.S. I am required by the FTC to disclose (as I already did, but here it is again, explicitly) that I received this book for free.

Richard Taruskin: The Oxford History of Western Music, volume 1

Sunday, March 28th, 2010

One of my 2010 projects is to read this 4000 page, 5 volume history of Western classical music. It got outstanding reviews when it was published in 2005, and last year it was released as a reasonably-priced set of paperbacks, and when I finally got to browse them in the bookstore I was impressed enough to make the investment in time and money.

I’ve just finished volume 1, which takes us up to 1600, so I’m pretty much on track to finish this year (I figure my pace will go up once I get to the music I’m much more familiar with, about halfway through volume 2). It was very interesting, especially since I didn’t know a lot about the early evolution of classical music already.

Despite the fact that the work as a whole is thousands of pages long, Taruskin clearly intends this to be read front to back as a narrative; it’s not a reference, or even really a textbook. This has many advantages and a few disadvantages. One nice thing (to me) is that it is clearly written with some subjectivity; although of course he is writing a history, the author isn’t afraid to inject his own opinions on occasion, which makes it a much more interesting read than it could be. The biggest disadvantage to me is that it’s not as easy to use as a reference as a textbook would be. If he introduces some new term, it’s not going to be in boldface or set off in a sidebar; if you run into it again later and forget its meaning, you’ll have to flip around looking for its definition (and it’s not always in the index). This was a real issue for me in this volume because I’m unfamiliar with most pre-1700 musical jargon. On the other hand, I’m reading it for pleasure, not so I can pass an exam, so it wasn’t a huge deal.

He makes a big point about this actually being a history of written music, which is very different from being a history of music; we really don’t know a lot about pre-literate performance, or even a ton about the performance of the works we have scores of. And of course a lot of written music has been lost, or even intentionally destroyed (grr). So it was neat to read about the ways in which we have to piece together knowledge about what music was really like during this period.

The material itself I found really interesting. I wish I got a slightly better sense of the evolution of certain musical vocabulary from a more theoretical point of view. For example, somewhere during the hundreds of years covered by this book, harmony gradually changed from being mostly just a succession of consonances into having semantic meaning on a more “sentence-sized” level. Taruskin points to some individual examples of this, but I found myself wishing for a higher-level overview of how the shift occurred. Of course, the individual composers who made this shift happen probably didn’t think about it that way at all, so any attempt to impose some sort of teleological post-facto history on it is going to be pretty artificial anyway.

In any case, so far the series has been very entertaining and informative, and I’m not regretting my time spent with it at all. On to Monteverdi!

Michal Ajvaz: The Other City

Sunday, March 14th, 2010

This is a short Czech novel from 1993 that just got translated into English last year and showed up on lots of SF/weird readers’ 2009 best-of lists. The genre is magic realism, which is to say highly-literate fantasy that takes place in the real world. The narrator (I don’t think he ever gets a name) starts discovering clues to an alternate fantastic city that exists in parallel to Prague (shades of China Miéville’s The City & the City). And this other city really is fantastic, full of arresting poetic images that don’t make much rational sense.

Those images, at their best, are really gripping and memorable — two scenes that come to mind are a fight to the death with a shark on top of a tower and a bushwhacking expedition through a library-jungle — but just as often seem more random, as if the author was picking words from a dictionary and then trying to connect them in some sort of Oulipian manner:

“Of course it was all in vain, you fool,” she said disdainfully. You purged geometry of polar animals… You’ve forgotten that the first axiom of Euclid states that there will always be one or two penguins in geometrical space? Wasn’t it you who tattooed that sentence on my thigh in your automobile of ice? […] You turned us against you when we discovered you on the lavatory squeezing oranges onto a pocket calculator. We don’t like you and find you ridiculous.”

Which rather than making me savor each crazy image makes me just skim until I can find something that makes a little sense again.

So although there are some reoccurring images and themes that do give the book some structure, I sometimes had the same experience I have with David Lynch movies, where, after a bit of seeming to have some strange internal logic that is tantalizingly just beyond the reach of my rational mind, the work just goes off the rails entirely. It was short enough and cool enough that I am perfectly happy with the time I spent with it, but overall for me it didn’t fulfill that top-ten promise it started out with.

Go problem books

Saturday, February 27th, 2010

I haven’t had much to write about books lately, for a couple of main reasons: I’m trying to get all the way through Taruskin’s Oxford History of Western Music in 2010, which is close to 4000 pages long, and I got sucked back into the game of Go (I’m using the Korean word, baduk, for the tag since that seems to be the standard search term – “Go” is pretty terrible for obvious reasons).

I got to my current level (AGA 4 kyu) largely by reading lots of instructional books, which is pretty much the main way I like to learn (which is also true of chess or math or science), as opposed to playing a lot or doing lots of exercises. But I’ve become convinced that the way to really improve is to actually do a lot of problems, and in both chess and Go that’s what I’ve been concentrating on lately.  So here are some of the Go problem books I’ve used in the past and present and what I think of them.

Graded Go Problems for Beginners (4 volumes). When I am forced to give only one recommendation for problem books, this is it. It’s a super collection of all sorts of problems, although by the later books it concentrates a bit overmuch on life and death, which gets a little tedious. Volume 1 starts at the very beginning (e.g., capturing stones in atari), so if you have any experience at all you probably want to start with Volume 2, which is still pretty basic but even I still spend an hour reviewing it every once in a while (like when I’m returning to the game after a break). Volume 4 is probably useful all the way to 1 dan level.

One Thousand and One Life-and-Death Problems. Exactly what it says. Starts out around 10k level, probably close to 1d level by the end (I’m only on problem 534 so far so who knows!). They can get a bit samey after a while but doing life and death problems is the single best way to improve your reading skill.

Get Strong at Tesuji. A good collection of tactical problems from ranging from very easy to 1d level. One nice thing is that a lot of them are mainly about making good shape rather than more obviously concrete goals like living or killing or separating or connecting. So you’ll learn how to place your stones effectively and flexibly in the first place, which will put you ahead of the game when the actual living and killing problems come up.

Lee Chang Ho’s Selected Life and Death Go Problems (李昌镐精讲围棋死活). Tons of people raved about this series of six Chinese books so I had to pick them up. The nice thing about problem books is that it doesn’t matter a lot if you don’t know the language (which I don’t); the diagrams have most of the information. Anyway, these problems are indeed great; they feel interesting in a way that some other collections don’t, and they build on each other nicely. Volume 1 is probably tractable at 10k, I pretty much hit a wall in Volume 4, and Volume 6 is probably suitable for dan players.

Lee Chang Ho’s Selected Tesuji Go Problems (李昌镐精讲围棋手筋). Naturally I had to pick up his tesuji series as well. This had gotten less stellar reviews, but I like it just as much. The problems are simpler, but that’s good; this is basically a giant practical compendium of all the standard techniques you should have in your fingers during the middle game, so it’s more for, say, reminding you that if you’re trying to connect two groups you should think about clamping the opponent stone sitting between them than it is for practicing intense reading. I’m only in Volume 3 so I don’t know how hard it gets, but I’d say you could get a lot out of this at 10k.

Cho Hun-Hyeon’s Lectures on Go Techniques and Lectures on the Opening. So far two out of three books have been translated in the former series and just one of the latter. These are really super. At least in Volume 1 of each series, the problems are very simple, but 1) even I only get them 90% right and it should really be 100%, and 2) he goes into detailed explanations about why alternative moves are bad, in a way that is incredibly useful when you’re learning and don’t have good shape intuition yet. Lectures on Go Techniques Volume 1 is about simple joseki (although it doesn’t really feel that way; it’s more about “applied fundamental principles”) while Volume 2 takes that knowledge a little further into the middlegame. Lectures on the Opening is more about opening principles, which you likely have picked up somewhere else but are always useful to review.

But again, if you want to start with just one book, I still would go for the relevant volume of Graded Go Problems for Beginners and take it from there.

Cardiacs – a video primer

Sunday, January 31st, 2010

Cardiacs are my new favorite band of all time. They’ve been around since the early 1980s at least but astonishingly I never heard of them until last year, when I discovered the video for their early song “Tarred and Feathered” (not for the faint of heart or ear), which made me gape deliriously with a “you can make music like that?” reaction, one I’ve only had a few times in the past (Conlon Nancarrow and Phil Kline come to mind).

They’ve been described as “pronk”, or “prog-punk”, and I guess I can see that; there’s the musical interestingness of a lot of prog, combined with a punk sort of energy. Some of my favorite bands (the Pixies, the Minutemen, etc.) have that sort of mix, in varying ratios, and it rarely fails to please me. With Cardiacs the music is even more out there than usual, though.

It is amazing how relatively obscure they are — I spend a lot of time looking for music like this, and I somehow was able to miss them for decades — but fortunately they’re really well represented on YouTube, partially because the fanbase they do have is so rabid. Here are ten links to explore, in roughly chronological order, if the above description sounds appealing.

  • Gibber and Twitch (rehearsal (with misspelled title)) is a great example of their early hyper can’t-stay-in-one-place-for-more-than-ten-seconds style, though it’s actually a 2003 rehearsal video (there are keyboard parts you can’t see played because they use backing tapes in performance these days).
  • Tarred and Feathered (video) is an amazing piece of work, with enough musical ideas for four songs, and the gonzo ‘performance’ (the keyboardist and percussionist, at least, aren’t making any attempt to play their real parts) makes for one of the more arresting videos I’ve ever seen.
  • Big Ship (live) is off-the-wall and catchy at the same time, with a giant maestoso singalong chorus at the end that gives me chills. A good litmus test – if this is too crazy for you, you probably don’t stand a chance with most of their repertoire, but if you can imagine acquiring this taste, the rest will probably follow.
  • Everything Is Easy (live) is pretty straightforward but boy does it rock.
  • Is This the Life? (video) is their one hit, so I have to include it here, but honestly it’s one of my least favorite songs of theirs – it sounds like a Cure song to me.
  • Baby Heart Dirt (live) shows off their early funhouse style with an awesome riff and some great synchronized instrumental insanity in the second half.
  • Odd Even (music) is unusual in many respects for a Cardiacs song, but it shows that Tim Smith can write pretty (but still quirky) ballads when he wants to. And that keyboard solo!
  • Fiery Gun Hand (music) rocks with a righteous fervor, and as with Baby Heart Dirt, the second half of it is stuffed with more random awesome musical ideas than you can count.
  • Dirty Boy (music) is for many fans the ultimate Cardiacs song, nine majestic minutes of slowly-moving chords, spiraling ever higher and higher.
  • Wind and Rains Is Cold (fan video) is from their last full-length (so far), Guns. Not the one song from that album I would have chosen, but it’s the one I can find on YouTube, and it’s nice to have something like this after all the rockers above to show off their range a little.

Jeff VanderMeer: Finch

Sunday, January 31st, 2010

After finishing Shriek: An Afterword, I dove right into VanderMeer’s third Ambergris book, Finch. This is in yet another style — it’s a hard-boiled detective novel set in a dystopian future a hundred years after the events of the last book. It’s pretty cool how willing he is to play around with many different styles in the same world.

Despite my appreciation for it, it wasn’t totally successful for me, for reasons that are not really the author’s fault. For one thing, it’s a very grim book, and it turns out I wasn’t really in the mood for grim at the time I read it. Also, it resolves a bunch of mysteries from the first two books, but as you can guess from the word “dystopian” above, not in a very happy way. It made me sad that some of the open questions about Ambergris and the underground gray caps from City of Saints and Madmen that at the time were a neat mixture of charming and menacing turned out to be just menacing in retrospect. I’d almost rather imagine this book as one possible future history of Ambergris than as the one true author-approved one.

Anyway, as a book it was quite good despite my negative reactions above. The plot took a little while to get started and had just one or two too many components for my taste but was interesting and held together, and there were a few great “whoa” moments, as you would hope for in a fantastic (in genre) book. I’m not sure how much sense it would make if you hadn’t read the earlier books, but the first one (City of Saints and Madmen) is the one I would recommend for newcomers to Ambergris and VanderMeer anyway.
