Friday Random Ten, July 31

  1. Russian Circles, “Youngblood”: post rock, in the Mogwai style. Very nice stuff. Not the
    most exciting PR band around, but good.
  2. The Flower Kings, “World Without a Heart”: typical FK. Since I pretty much worship the ground
    that Roine Stolte walks on, you can guess what I think of this.
  3. Darcy James Argue’s Secret Society, “Transit”: would you believe sort-of progressive
    big-band jazz? That’s pretty much how I’d describe this. Big band jazz is not my usual cup of tea, but
    this is damned impressive, and a good solid listen. Definitely very cool stuff.
  4. Naftule’s Dream, “Yid in Seattle”: Naftule’s Dream is an alternate name for a wonderful
    Klezmer group called Shirim. When they’re doing weird stuff, they record as ND; when they’re doing
    traditional, they record as Shirim. ND is klezmer the way that John Zorn and his radical jewish
    culture guys play it. Wild stuff. Brilliant.
  5. Sonic Youth, “Leaky Lifeboat (for Gregory Corso)”: a track from the newest Sonic Youth
    album. This actually sounds more like older SY. In general, they’ve mellowed a bit over
    time; in particular, they’re last album had fewer rough edges. This one keeps the smooth
    production, but brings the edge back to the sound. SY just keeps getting better.
  6. The Tangent, “The Ethernet”: the Tangent started out as a collaboration between
    Roine Stolte of the Flower Kings, and Andy Tillison of Parallel or 90 Degrees. Stolte eventually
    quit, leaving Tillison running the band. It’s completely replaced Po90D as Tillison’s main band.
    It’s not quite up there with tFK, but it’s damned good.
  7. Keith Emerson Band, “Prelude to Hope”: This is an astonishing track. It’s Keith Emerson
    playing something beautiful and subtle. I’m a big Emerson fan. He’s a brilliant pianist.
    I love his style, and I usually love his compositions. But my opinion of him in the past was that
    if anyone were to suggest that perhaps he should try being a bit more subtle, he’d
    be likely to bash their head in with a sledgehammer, put the body through a wood chipper,
    collect up the bits and burn them to ashes, and then piss on the ashes – just to make sure
    that he made his point clear. And yet… This is a beautiful, subtle piece of playing, from
    a frankly terrific album.
  8. Echolyn, “Lovesick Morning”: Echolyn is one of my favorite recent discoveries. They’re
    not exactly a new band – they formed in the early 90s, broke up in 95, and then reformed
    a couple of years later. But they’re a thoroughly excellent neo-progressive band, with a very
    distinct sound. They don’t sound like they’re trying to be Genesis, or the Flower Kings, or Yes… They
    sound like nothing but themselves.
  9. Frank Zappa, “Drowning Witch”: Typical Zappa. Very strange, wonderfully erratic
    but great music, and incredibly silly lyrics delivered in that strange Zappa style.
  10. Dream Theater, “Wither”: Dream Theater’s newest. DT is a great progressive
    metal band. Their last few albums were a bit uninspired in my opinion. This one is really
    quite good. Unfortunately, this is one of the weaker songs on the album. Not bad, but not
    exactly what I’d choose to try to turn someone on to Dream Theater.

Bill O'Reilly on Life Expectancy: Dumbest Man on Earth?

An alert reader just sent me, via “Media Matters”, the single dumbest real-life
video clip that I have ever seen. In case you’ve been living under a rock, Bill O’Reilly is
a conservative radio and TV talk-show host. He’s known for doing a lot of really obnoxious
things, ranging from sexually harassing at least one female employee, to sending some of
his employees to stalk people who he doesn’t like, to shutting off the microphones of
guests on his show if he’s losing an argument. In short, he’s a loudmouthed asshole who
gets off on bullying people.

But that’s just background. As a conservative commentator, he’s been going off on
the evils of Obama’s supposedly socialist healthcare reform. That’s frequently
taken the form of talking about how horrible medical care is under Canada’s
socialized health system. One of his viewers wrote in to him about this. And
the insanity follows.

The question came from a viewer named Peter from Victoria, BC, who asked: “Has anyone noticed
that life expectancy in Canada under our health system is higher than the USA?”

Bill’s response:” Well, that’s to be expected Peter, because we have 10 times
as many people as you do. That translates to 10 times as many accidents,
crimes, down the line.” Delivered, of course, in BillO’s trademark patronizing
style.

Friday Recipe: Chinese Potstickers (aka Jiao Zi)

dumpling.png

My wife is chinese. So in our house, comfort food is often something chinese. For her, one of her very favorite things is dumplings, also known as pot-stickers. They’re time consuming to make, but not difficult. They’re really delicious, well worth the effort. They’re best with a homemade wrapper, but that’s not easy. If you go to a chinese grocery store, they sell pre-made dumpling wrappers with are pretty good. Not as good as homemade, but more than adequate. The wrappers are circular, and about 2 or 3 inches in diameter.

These are traditionally made with ground pork. But I don’t eat pork, so I use chicken thighs. Definitely make sure you use thighs – to come out right, the meat inside can’t be too lean – it needs to have some fat in it. Thighs work really nicely; breasts, not so much.

When my wife stuffs them, this recipe makes around 30 dumplings. If I’m stuffing them, it’s more like twice that – she somehow manages to stuff an amazing amount of filling into each dumpling. If I try that, I can’t close ’em.

Ingredients

  • 3 boneless, skinless chicken thighs.
  • 1/2 medium sized head of napa cabbage (about 1lb).
  • Thinly sliced green parts of two scallions.
  • 1 tablespoon Oyster sauce.
  • 1/4 teaspoon sesame oil.
  • 1-2 tablespoons soy sauce (to taste)
  • A small dish of cold water.
  • Dumpling wrappers.

Instructions

  1. Put the chicken thighs and the oyster sauce into a food processor. Pulse until you’ve got what looks like coarsely ground meat.
  2. Finely mince the cabbage. Don’t do it in a food processor – that’ll just pulp it. You want it minced into little pieces.
  3. Fold the cabbage, soy sauce, and sesame oil into the ground meat.
  4. Now you’ve got the finished filling. Take a wrapper, put a dollop of filling into the center of the wrapper. Lightly brush the edges with water, and then fold the wrapper in half, sealing the edges. (The really correct way of doing it crimps it so that it actually looks like a crescent moon, and stands up by itself. But I have no idea how to explain that! And it tastes good even with the lazy fold.)
  5. Keep doing that until you run out of either wrappers or filling.
  6. Heat up a shallow frying pan on medium to medium-high heat. Cover the bottom with oil. You want enough oil to fry the bottom of the wrappers, but not enough that they’re swimming in it. And you only want the bottom to fry. (Don’t use a wok for this. This is one of the only times that I’ll ever say that about chinese cooking – but you really want a flat bottomed pan.)
  7. Put the dumplings into the pan in shifts. You don’t want them too close together, or they’ll stick to one another. Let them cook for one or two minutes, until the bottom is a nice dark brown.
  8. Take about 1/2 cup of chicken stock, dump it into the pan, and immediately cover the pan tightly. Let it cook like that until almost all of the stock evaporates. Then take the dumplings out, and put them in a serving bowl. They’ll stick to the bottom a bit; pry them up gently with either a spatula or tongs. (There’s a reason that they’re called pot-stickers!)
  9. Keep going in batches until they’re all cooked.
  10. Serve them with a dipping sauce. Spoon a bit of sauce over each dumpling right before you eat it.

There are a ton of dipping sauces you can use. My own favorite is:

  1. about 1/4 cup of clear rice vinegar
  2. About 1/4 cup of soy sauce
  3. 1 teaspoon of sugar
  4. one clove of crushed garlic, finely minced.
  5. One slice of ginger, crushed and finely minced.
  6. Greens of one scallion finely minced.
  7. One drop of sesame oil.
  8. One half teaspoon of sambal or sriracha chili sauce.

These little suckers are seriously good eating. They’re sort of like potato chips, in that once you start eating them, you can’t stop. So make a lot!

If you really want to make homemade wrappers (which is a lot of work, but which makes these wonderful little things so much better that you’ll never go back to store-made wrappers), there’s a great recipe for them in Ming Tsai’s “Blue Ginger” cookbook.

Bad Healthcare Cost Models Produce Silly Results (anyone surprised?)

This morning, my good friend Orac sent me a link to an interesting piece
of bad math. Orac is the guy who really motivated me to start blogging; I
jokingly call him my blogfather. He’s also a really smart guy, not to mention
a genuinely nice one (at least for a transparent box of blinking lights). So
when he sends me a link that he thinks is up my alley, I take a look at
the first opportunity.

Today, he sent me a link to a guy who claims to have put together
a mathematical model showing that it’s impossible to create a national
healthcare system without rationing. The argument is a great example
of what I always say about mathematical modeling: you can’t just
put together a model and then accept its results: real mathematical models
must be validated. It’s easy to put together something that looks
right, but which produces drastically wrong results.

The common way of saying it is “Garbage In, Garbage Out”. I personally
don’t like that way of describing it – because in the most convincing examples
of this, it looks like what’s going in isn’t garbage.

High School Reunion: New comment thread

We’ve been having some load trouble with the ScienceBlogs server, and the
400+ comment over on the high school reunion thread seem to be resulting in a lot of timeouts. In an attempt to reduce the number of errors, I’m closing the thread on that post, and asking folks to post any new comments here.

Friday Random Ten, July 17

  1. John Corigliano, “Fantasia on an Ostinato”: Corigliano is absolutely my
    favorite modern composer. He writes stunningly beautiful music. This is a wonderfully
    subtle piece: unaccompanied solo piano. Just incredible.
  2. Isis, “Not in Rivers, But in Drops”: The transition between the last one
    and this just about scared me out of my seat. From solo piano to loud, heavy
    post-rock. Once the shock of the volume change was past, I love this track. Isis
    is a really fantastic group.
  3. Dirty Three, “Amy”: Dirty Three is another interesting transition. DT is another
    post-rock, but from the opposite end of the post-rock spectrum from Isis. DT is mostly
    accoustic, heavily classically influenced post-rock. Most of their studio work doesn’t have
    the energy or the focus of a band like Isis, but it’s still very good stuff.
  4. Trans Am, “(Interlude)”: from post-rock to math rock. Trans Am is a pretty neat
    little band. Not nearly as good as some of the others in my collection, but definitely fun.
  5. Jadis, “Need to Breathe”: Finally, some neo-prog. Jadis is a new neo-progressive
    group that’s heavily influenced by Marillion. They’re pretty good. Not great, but good.
  6. Broken Social Scene, “Our Faces Split the Coast in Half”: a big disappointment. I heard Broken Social Scene being interviewed on NPR. They’re a Canadian collective, which has
    some overlap with the deities of postrock, “Godspeed you Black Emperor”. The bits they played
    live sounded great. But when I got one of their albums, it’s profoundly dull. Pretty much
    the only time I ever listen to it is when it comes up in a random playlist, and then
    I usually wind up skipping past.
  7. Echolyn, “The End is Beautiful”: very good neo-progressive rock. Maybe a tad on the emo side,
    but the quality of the musicians more than makes up for that. Seriously good stuff,
    very highly recommended. Includes a really beautiful fugue section.
  8. Gong, “Magdalene”: Brilliant prog-rock, with nothing neo about it. Gong has been
    together since the 70s (although I just recently found out about them). They’re one of the
    most amazing bands I’ve ever heard. Very strange, very silly at times, but always
    musically brilliant. They’ve got unusual instrumentation – very woodwind heavy for a rock
    band. I can’t recommend them highly enough.
  9. Alan Holdsworth, “The Sixteen Men of Tain”: Alan Holdsworth is someone who’s music
    I simultaneously love and hate. The guy is, without a doubt, one of the most skillful
    and artistic guitar players ever. He can play fast or slow with every note being crisp
    and perfect. He can play rock, jazz, and classical guitar with equal skill. And yet,
    most of the time, he leaves me cold. He’s like a guitar playing machine – perfect in every
    mechanical way, but somehow, his playing just totally lacks humanity.
  10. The Flower Kings, “The Blade of Cain”: The perfect ending for a FRT: my
    favorite band, the Flower Kings. These guys are the neo-progressive band
    to watch. Brilliant composition, brilliant performances. They come closer to musical
    perfection than any other rock band I’ve ever seen or heard. I found a youtube clip
    of them performing this track live, so you can get a sense of what I mean, which is below.

Chaotic Systems and Escape

nbody.jpg

One of the things that confused my when I started reading about chaos is easy to
explain using what we’ve covered about attractors. (The image to the side was created by Jean-Francois Colonna, and is part of his slide-show here)

Here’s the problem: We know that things like N-body gravitational systems are chaotic – and a common example of that is how a gravity-based orbital system that appears stable for a long time can suddenly go through a transition where one body is violently ejected, with enough velocity to permanently escape the orbital system.

But when we look at the definition of chaos, we see the requirement for dense periodic orbits. But if a body is ejected from a gravitational system, ejection of a body from a gravitational system is a demonstration of chaos, how can that system have periodic orbits?
