Rolling Stone

I gather analysis isn't their strong suit. The sex scandal at Duke story has a few oddities that suggest that the reporter hung around with campus elites. Duke has 6500 undergrads, and they can't all hang out at Shooters. The author hung out with frats and sorors and talked about athletes. It makes for a juicy story, but I'd be more convinced if he'd talked to some chemistry majors too.

And they've an innuendo story about stealing elections . I judge that voting without a paper trail is a recipe for trouble. But I'm afraid that wishful thinking and skewed polls are not useful evidence of wrongdoing.

Both stories use biased sampling to try to reach conclusions (or more accurately, to give impressions and let us reach conclusions). I suppose reporters (not generally the best-educated among us) are never taught anything about statistics, and the editors seem to be no better. And I suppose a magazine devoted to the entertainment world isn't so used to looking past impressions to look at the details: impressions are a lot of what entertainment is about.

Rolling Stone is hardly the only offender (they're just handy). Think about the recent stories about the number of lives hospitals saved with more careful procedures in the last year and a half--and ask how many accidental deaths there were before, and start getting suspicious.

Wyalusing

Eldest son kept having butterflies (the tabby kind about 3 cm long) land on him and probe for water/ whatever (puddling, I think it is called). He wore a hummingbird-red shirt and had sprayed insect repellant on himself. Do butterflies like Deet?

The wind was strong enough to make my bottle sing its note if I held it just so. After a while youngest son figured out how to make his sing too.

I'd strained my Achilles tendon at the heel, and had an excellent excuse for not climbing bluffs. Unfortunately even the milder walks seem to have had ill effects.

I wonder where the Mound Builders went? There were some substantial migrations when the Iroquois started moving west--I recall reading that the Sioux were originally from the Iowa/Wisconsin neck of the woods.

For that matter, why do the bears and panthers have such round heads? Is that stylization or erosion? I tried to think up reasons for effigy mounds. Everybody thinks "totem," but it could be something like emblem: a memorial built when a leader from the bear clan or porcupine clan or clamshell clan (my idea--you'd get a conical mound that way :-)) was in charge.

It might make an interesting Boy Scout project for them to learn about and try to build their own mound. If it was 20' by 10' by 3' high and rounded, I'd guesstimate 300 cubic feet of dirt. Carrying the dirt isn't that big a deal, especially if you cheat and use inventions like wheelbarrows or the shoulder pole--digging is the hard part. If every boy moved 2 cubic feet of dirt in a day, that'd be 150 boy-days. If several groups got together (I suppose they'd have to, since you'd only build something like this on Scout property), they could build a fairly respectable mound in a couple of days without too many blisters.

Super Absorbant

The "superabsorbant" waffle-weave towels are supposed to be more absorbant and more durable than the usual tufted fabric ones. (They're also more expensive.) Well, a 18 inch by 36 inch one isn't enough to completely dry off a 6 foot tall man who is sopping wet. Your mileage may vary.

Monrovia Mon Amour

A visit to Liberia by Anthony Daniels

Anthony Daniels may be better known by his pseudonym Theodore Dalyrymple. He is a doctor and psychiatrist and a fine writer.

This book dates from 1992 and describes his observations from what must have been a couple of weeks visit to Monrovia during a time when the Interim Government of National Unity ran Monrovia (with the help of Ecomog aka Every Car Or Moveable Object Gone) and negotiations were in progress. Doe’s men still held the Executive Mansion and the military camp.

On the morning of my arrival in the Ivory Coast I learned that the Steel Trader was due to sail from Abidjan for Monrovia and I went straight down to the ‘Port Autonome.’ A man in khaki uniform, reclining on a bench like Madame Recamier, barred my way. I was not allowed to enter the port.

’Where are you going?’ he asked.

’The Steel Trader,’ I replied.

’Why?’

’I am a doctor,’ I said, leaving open the possibility that a terrible epidemic had broken out on board.

’Do you have medicine with you?’ asked the official.

’Of course,’ I said.

’I am always tired, doctor,’ said the guardian of port security.

’Why?’ I asked.

Laboriously, he levered himself up on to his elbow.

’Too much work,’ he said.

I searched in my box of time-expired medicaments for something suitable, and alighted on erythromycin, vivid pink antibiotic pills that looked as though they would glow in the dark.

’These,’ I said, ‘are very good for tiredness.’

’How many do I take?’ he asked.

’One a day, until you are no longer tired.’

’Merci. Bon voyage, docteur,’ said the official, collapsing back on to his bench.

That was the end of immigration and customs formalities in Abidjan.

The above is the first page of the book, and gives you a flavor of both the man and what he finds. (I’m violently allergic to erythromycin myself, and find his choice of medicines startling.) He toured the Masonic building, the University, the Maternity Hospital, and tried to invoke a feeling for the often banal existence before the violence, and from there arrive at an understanding of the destructiveness of that violence. For example, the Maternity Hospital was thoroughly looted and wrecked; the papers from it used apparently as toilet paper. Apparently only the medical records were so used, and not the more mundane correspondence, and from this he mused about the way the white man’s medicine must have evoked resentment from those whose world-view it was overthrowing. Maybe it did cause resentment, but he forgot that the looters were mostly illiterate; and a more mundane explanation might be that the medical records, on sturdier stock than typing paper, were a more useful substitute for the traditional toilet of large leaves.

He attended the All-Liberia Conference, discovering later that “the middle of the day was a good time to travel if you wanted to avoid road-blocks, because it was then too hot for security, and the soldiers would languidly wave you through from under the shade of a tree.” Of course the “history-making” conference made no history or breakthroughs. “The delegates sat around the tables, deep in political discussion. Lunch was delayed by an hour and a half. When finally the food arrived, there was a scramble for it as desperate as the scramble in which I had participated at Lagos airport one the boarding of the aircraft was announced (The Togolese market women had brushed me contemptuously aside with their baskets, seemingly laden with lead ingots). The leaders of the nation were terrified that there would not be enough lunch for them.” There he also met Tipetoh (leader of MOJA; Movement for Justice in Africa), whom he shreds (“He kindly gave me the Preface, a single sheet of paper, and also a large photograph of himself: in my experience, the few people who genuinely believe in the equality of man do not carry photographs of themselves in their attaché cases for distribution to as many people as possible”)

He later arranged to meet Prince Johnson, and was even more horrified by his vice-Marshall Varney than he is by Johnson. Still later he arranged to see the infamous movie of Doe’s murder by Johnson, and was startled at the glee his hosts display re-watching it.

Along the way he met and was suitably perturbed by various people with ill-concealed pasts—people who had active roles in the massacres on one side or another.

Memory can be a fuzzy thing sometimes, and many of the places he described are either places I didn’t visit more than once, or were built after my time. Providence Baptist Church—he slipped out of the service at the new building, which was still under construction when I left. Some of the ruins are of places not yet built 30 years ago, which makes his references hard to follow.

He toured JFK hospital, and the massacre site of St. Peters, and found some of Doe’s family still living in Doe’s house. He even got permission to tour the Barclay Training Center where Doe’s army remnant still camped, and eventually even the Executive Mansion. Along the way he met still more villains, but I have the feeling that a lot of his reaction was read into the men from what he knew of them; a reaction to his knowledge rather than to them personally. But he is honest with himself here. He attended an interview of General Brown by a Swedish TV team (and FWIW he found them an exception to the usual Swedes in Africa whom he describes, “I feared the compassion of the Scandinavians as I feared the cruelty of other peoples, for their compassion was simultaneously neurotic and abstract, sentimental and ruthless.” Yes, he justifies this with examples.). This Swedish team is interested in digging out stories, and grills the General, who says at the end of the interview “’You have asked a lot of questions,’ he said. ‘Now it is only fair that you should answer ours.’”

There were several questions I could think of which might have caused us some embarrassment: had we come to Liberia to further our own careers, did the destruction we found there confirm us in our feelings of cultural superiority, were we enjoying ourselves amidst the ruins, did the level of suffering in Monrovia match up to what we had expected and hoped for, or were we disappointed in it?

Dr Daniels doesn’t say as much outright, but the answers would probably have been “Yes,” or something closely kin to it. He is very sensitive to matters of architecture and culture, and sees meaning in things (such as the carefully sawn-off legs of the only Steinway piano in Liberia) that don’t always resonate with other people. His insights misfire sometimes, but he hits the nail on the head at others. The fall of every sparrow is attributed to some CIA conspiracy, because people want meaning in their lives and the notion that America just doesn’t care about Liberia is intolerable to them.

The situation in Liberia is now very different, of course. The corruption is still there, but for now there’s no war or threat of war. This dates the book slightly. Someone who had spent years there would no doubt have written a more accurate book. But the glimpses of what life is like with decommissioned murderers in the neighborhood are still useful. This book is good despite its flaws, and I recommend it.

20 months old

Neighbor Toby is twenty months old. He is cheerful and adventurous, and he speaks entirely in consonants, like the groundhog child Grundoon from the old Pogo comic strip. Yesterday he and his mom and brother were here because I had a new washer delivered, and every little boy loves to watch a big truck. Toby and brother Sammy, age 5, love exploring somebody else's house, and were thrilled to pet and play with our rabbits.

Toby's mom showed him our irises, which are huge and purple. The irises stood taller than Toby. We grownups forget what the world looks like from that level. I watched Toby reach up for a blossom, with the leaves framing his face. I remembered other adventures with our own kids, when their angle of view revealed delights I missed: the bumblebees hiding under a goldenrod during a shower; clams in the weeds under the "belly boards" along the marsh boardwalk, and the plain joy of counting frog noses in the pond.

No more drudgery!

I’ve never been a fan of fufu myself, but if hours of drudgery can be done away with, this might be a good idea. Of course, it has to be affordable; but the miller was a fixture in Medieval England—he made wheat convenient enough to warrant the extra cost.

Is That a Hint?

I’ve been reading Spiritual Disciplines for the Christian Life by Donald Whitney. This afternoon I read the chapter on fasting. As soon as I was done we went to a Memorial Day party at the neighbor’s house. (Two brats, red beans and rice, ice cream…) I came back after a while and started reading the chapter on Silence and Solitude. Youngest Son came home a few minutes later and started telling me all about his planned parody of Star Wars, with a “Death Grill.” All the details about it.

Hand-Me-Ups?

At lunch today Youngest Son announced that he was “giving his Lord of the Rings action figures as hand-me-downs” to Youngest Daughter. He is 12. She is 15.

Why no book reviews?

I have been writing, just not here. Our church needs some material for introductory classes, so I wrote it. What with the many other things going on at the same time (writing DAQ software for one experiment, scrounging parts for a spark chamber demo, working on the silicon detector trigger for another experiment, trying to revamp a muon trigger, and puzzling through an astrophysics problem--not to mention family obligations) I've been a wee bit short of time.

I don't really think of them as book reviews so much as holding up my end of a dialog between the author and myself.

But I've read a few books along the way. Developing Talents by Temple Grandin is about how Aspergers folks can find jobs. I'm buying our own copy. Ten Questions to Diagnose your Spritual Health by Donald Whitney is just what it says: a set of questions and examples to set you trying to decide what is keeping you from growing as a Christian and how to get rid of it. Not perfect, but very much worth reading and thinking about. The Day of the False King by Brad Geagley is the second book (oops) in a series of detective stories about an ancient Egyptian detective. My wife says the first (The Year of the Hyena) is better, which doesn't surprise me. The False King tries very hard to give a flavor of the environment, but leaves out lots of details like what people ate--it left an unbalanced feel. The Insect Room was both a foolish plot-hole and not nearly so horrible as the real punishments the Babylonians had in store.

I still plan to write about Dogs of God.

I'm reading slowly through Prayer; re-reading Watership Down (we've got a new rabbit), reading The Seven Pillars of Wisdom, Persian Mirrors, Reflections on the Psalms, From Babel to Dragomans, Exploring Java, and re-reading My Favorite Intermissions.

I don't think I'll be finished with any of them this week.

DaVinci Code

I've been hearing two reactions in church to the upcoming movie: opportunity and boycott.

Boycott is the wrong word for my reaction. Boycotting presumes that I would be withholding my regular business. But that's backwards: it is the movie-makers' job to entice me to part with 20 of my dollars and 2 hours of my time. I looked at the movie listings, and none of them succeeded. There's almost nothing I'd bother to go look at even if it were free and next door. Maybe "Over the Hedge."

That doesn't even include the other demands on my time: I haven't even seen the Narnia movie yet, and that was on my list. (The kids have a copy, so I'll get to it sooner or later.)

So no, I won't be boycotting the movie. I won't be bothering.

And no, I don't think it offers an opportunity to discuss the foundations of Christianity with the curious. I judge that the popularity of the book comes because some people want to believe in secret conspiracies, and because there's been a huge PR push. People following the PR push don't care about whether it is true or not, and trying to reason with conspiracy fans is hopeless.

Time and Mother

The past is always with us. I feel this most with my wife: a moment with her recalls other moments. We shaped each other’s lives, and the marks each moment made are more than merely memories. We clean the kitchen, and in that time lives a little of the other times we’ve cleaned or kissed there. Not every echo is welcome—I remember times I’ve screwed up too—but each smile holds others; from shy beginnings to comfortable welcomings.

But my mother and I did not meet as equals. My parents were “in loco deus” for a while to me. True, I turned her life upside down (I was the firstborn), but I was completely unaware of that at the time. All I knew was that, for a time, she and my father were the center of my universe. Of course my universe grew, and eventually, thanks in part to their guidance, I met the God they served; and I have in my turn served (all too feebly) in the same capacity to my own children.

We meet as equals now: she a mother, I a father (and older now than she was when I left home). We’re equals and yet not equals, because the past is with us. The time for obedience is over, but the shape to my life from the times of obedience is still there for me, and the shape is there for her.

I remember, and try to imitate, her self-disciplined love—devoting her efforts to the needs we had, and looking out for ways to bring joy. I’m not nearly so good at figuring those out.

I love my mother.

Policeman to the world

The Darfur situation has been eliciting calls for intervention. Some of the same people are calling for us to intervene in the Sudan who despise our intervention in Iraq, though the latter would be justified by their own arguments. A lot of this looks like "When in danger or in doubt, run in circles, scream and shout" nonsense. These folks don't bother to think through the implications of action. "We've got to do something" isn't a plan. Stern rebukes didn't work, economic sanctions aren't going anywhere, so what's left? War or supporting a civil war.

I have no trouble with the assertion that Khartoum is the major culprit in this affair, or that Zimbabwe would be a happier land if Mugabe and a few hundred of his cronies lay at room temperature. These are almost certainly true statements. I also suspect that, on balance, Zimbabwe would be better off suffering a quick invasion, with all the destruction and turmoil that produces, if it succeeded in ridding them of the tyrant and gave them some help in reconstruction.

What I am afraid of is the soul-destroying attitude that says I have the right to do this because I know what's best. It is a dangerous temptation because the claim is (at least in these obvious case) so nearly correct.

I find that I cannot abide a holier-than-thou attitude in others. That reaction seems quite common. If I assert my right to judge other nations (either in my own capacity or as a citizen of a relatively benign country), I put myself in this same holier-than-thou position that I can't stand in other people. This naturally evokes an intense dislike from others, and it cultivates in me an attitude of superiority. And then it doesn't take very long to slide from "I am superior because I am doing the right things" to "what I do is right because I am superior." And then, of course, I become Mugabe myself.

Yes, I know that you are ethical, and will monitor yourself and not succomb to such temptations. But will you warrant the same for your children? And I'll guarantee that your grandchildren will not have your scruples. They'll inherit power, and experience it as entitlement.

I do not mean to impugn the motives of people who want us to become a humanitarian policeman to the world. There are a lot of terrible things happening, and we could help. You need to be either careless or hard-hearted to stand by and let them fester.

But I believe that we, and the world, will be far safer if we fight on more self-interested grounds.

We didn't resume the war against Iraq to liberate the people of Iraq from a brutal tyrant, though I hear that cited a lot as justification. That was a useful side effect, but not one of our principle objectives. We invaded for sound strategic reasons: the origins of the attacks against us lie in the vicious theocracies of Saudi Arabia and Iran, and Iraq provides a useful staging area; all the evidence said Saddam's nuclear and anthrax programs were alive and well (and there are still some missing pieces, as the report noted); we suspected (and later found the smoking gun for) Saddam's support for anti-American terrorist groups; we saw the sanctions program failing and judged that an Iraq in charge of most of the world's oil and nuclear armed was an unsupportable threat; and maybe, if we lucked out and the Iraqis locked onto a stable free government, we could start to drain the swamp of the Middle East.

Pretty much self-interest all the way, isn't it? And self-interest isn't pretty.

But I think "ugly self interest" will keep us humbler, and safer to the rest of the world and ourselves, than trying to be the world's liberator.

Sweet sentiments?

If your honey is a naturalist, fascinated by wild creatures great and small, perhaps she would appreciate what you find when you excavate into the small hole in the garden that conceals a nest, from which flies an annoyed bumbling mother bee. Will you offer her a bee mine, valentine?

Images

When I was young I saw shapes not just in clouds but also in maps. Everybody knows the Italian boot, but did you see that New Zealand is one also (albeit slightly broken)? If you look at Indonesia and the Philippines, you can see a skeleton riding a jet-ski.

Left Behind

Years ago Eldest Son was fascinated by constellations: not just any, but those of the Southern Sky. My wife decided he should have a shirt with the Southern Sky on it, and she got a dark shirt and fabric paint, and I painted the stars and lettering from Rey’s book. Eldest Son loved it, but outgrew it. Youngest Son outgrew it recently. The stars are still mostly there.

About the same time I picked up a packet of glow-in-the dark dots for stars, and mapped out where each star in the southern sky should be on the ceiling of my son’s room. With ruler and checklist and dots I spent several hours to do one quadrant of the ceiling. I wasn’t quite satisfied with the way things were turning out: reference marks were tricky and the pattern wasn’t quite right.

Evenings I generally spent with monitoring homework and other chores, and days had work to do. It has been over a dozen years, and the ceiling still only has one quadrant’s worth of stars. Eldest Son doesn’t live at home any more. I wonder if Youngest Son even notices the stars, or wonders why they aren’t all there.

The dresser and desk and original bed were gifts to Eldest Son from a neighbor in Aurora. (I fixed them up a bit) We chose the paint and accent wallpaper strip (of sailing ships) to match the furniture. You could tell it was a boy’s room, even without looking at the bookcase or the floor.

Eldest Son isn’t a boy anymore. A few relics of his are still in the room—a few figurines, a few books, the Space Shuttle poster—but most pertain to Youngest Son these days. Bionicle parts mingle with Legos (some of the Lego pieces I played with 40 years ago) and K-Nex on the floor now, and there’s a large box of pencils, which fascinate Youngest Son. A busted Space Shuttle is on the dresser and a crane (from the Crane Foundation, of course) hangs from the ceiling. The top bunk is abandoned to a K-Nex ferris wheel and roller coaster now.

Another half a dozen years and Youngest Son will be heading off for college too. I wonder what relics he’ll be leaving behind. I wonder if I’ll ever get the rest of those stars up.

Skits

The National Council of Less Commonly Taught Languages had a convention here in Madison this week, so the University language teachers had their students perform short plays for the group. Middle Daughter performed in a small sketch about Yoruba family life, with scenes set at home, at the Zo's (is that the right word for the Nigerian equivalent?)(EDIT: Nope. Babalawo. -Middle Daughter) home, and in the spirit world--all in Yoruba with English translations displayed on a screen nearby. (Spoiler alert) The old ways are the best--stay out of the rain!

The sound system needed some work--feedback several times--but the students had fun and so did the audience, some of whom actually spoke the language. I'm told that recordings of this will go to Nigeria and be shown at conferences there too. (EDIT: Well, I don't know FOR SURE if they'll send this one. They used the one from last semester at several conferences there, and I'm fairly certain they'll use this one too. Apparently, we're big stuff for being second semester speakers...)

I have never been in a conference like this before. Physics conferences are largely male, though religious ones have been more mixed. This one was largely female, and I've never seen so many children at a conference. They ranged in age from about 6 months to 13 or 14, and must have been at least a tenth of the total number present. (Most of the people with children were from our Universtity, and came to watch their students performing)

No, I didn't stick around for all the presentations. I should find out if there's DVD's of them.

Concert

I took Youngest Daughter to see Eldest Daughter's choir concert last night. Youngest Daughter's Community Concert was Sunday at St. Alberts, and quite fun: All Things Bright and Beautiful to the Hallelujah Chorus. The college choir had beautiful voices, lively tunes sung precisely, and startlingly few in the audience. I've no idea why; I've never seen so few present. Still, we had fun, from Je n'ose dire to the song about the demon.

The binder of music looked heavy--some of the singers seemed almost overbalanced as they held their binder at chin level before them and leaned forward to project.

Sorry about that

The triple posting wasn't really my fault, but I should have checked more carefully.

To try and make up for it, let me bring you up to speed on Butler.

You know Butler: he and his girlfriend Rose wrote the definitive book on cooking with fresh green herbs. They're not married yet because he's so superstitious: his horoscope said that the only time to tie the knot is between 1:23 and 1:41 in the morning. That's the parsely sage Rose-marrying time.

Radiation environments

The BBC report on the Chernobyl disaster's effects on wildlife has some interesting features. A lot of species not seen for decades are multiplying. As you might expect, animals can't sense radiation and nest anywhere. Initially things died in the hotspots: trees, horses, mice. But the Red Forest, where all the pines died, is growing back "albeit with stunted and misshapen trees."

"We marked animals then recaptured them again much later," he says. "And we found they lived as long as animals in relatively clean areas." The next step was to take these other mice and put them in an enclosure in the Red Forest. "They felt not very well," Sergey says. "The distinction between the local and newcomer animals was very evident." Mutation In all his research, Sergey has only found one mouse with cancer-like symptoms. He has found ample evidence of DNA mutations, but nothing that affected the animals' physiology or reproductive ability.

Grant that seriously defective critters won't survive long enough to be caught by the researchers. Nevertheless, apparently the survivors live as long as comparable mice not in a radiation environment. At the same time, imported mice don't do well in the radiation area.

To understand why this is interesting, remember that most radiation damage isnot done to the nucleus, but to the rest of the cell. Mutations aren't what kill you, its the damaged proteins that don't work anymore, membranes that leak, and so on.

What this seems to suggest is that one can breed for radiation tolerance. Not radiation immunity--that's no more possible than immunity to fire. Tolerance means that the cell can stand a somewhat larger than usual amount of damage without failure. You might be able to get this by duplication: making extra copies of proteins, for example. This would obviously mean that the mouse would need more food, so this feature would ordinarily be selected against.

It shouldn't be too hard to test: do mice found in the radiation environment have babies that require more food than mice found elsewhere? Grow more slowly on the same diet?

If they were different, then it would be interesting to create a mouse breeding pen with controlled levels of radioactivity. Technically it wouldn't be much of a challenge, though the PR might be a mess.

Update: The researchers did not respond to my inquiries

Unfortunately, changing names appears to be a side effect of teaching one's daughters how to post on your site. Blogger has an obnoxious little thing where one cannot change the name for one post, it changes them for all...
