Experiences

Crowley seems to have won the field. "Do what you will" seems to be the dominant touchstone for ethics. He meant, or at least professed to mean, that your true self would make appropriate decisions, but the simpler way (and I hope I may be forgiven for thinking it Crowley's true meaning) is to follow your impulses. We measure how strong we are by how strong our feelings and impulses are.

And in the society that resulted, the most valuable things are experiences. To see the Shire in New Zealand, or ride a hot-air balloon, or free climb El Capitan--OK, most of us aren't eager to take on the years of discipline to manage El Capitan, but watching the GoPro video is almost as good. Right?

A cruise in the Bahamas, see the pyramids of Egypt, a trip to Machu Picchu--what is on the usual bucket list? For that matter, what's on the unofficial bucket list--the things you want to experience but would be embarrassed to tell your friends?

The most valuable experiences are those that demand training and skill. The pinnacles of experience would be free-climbing K2, surfing a tsunami, sky-diving from orbit. Most settle for less. But after you've sky-dived, you will have to try to sky-dive while balancing on a skate-board, or while playing the accordion, or while trying to have sex.

Lots of people covet celebrity, which can be very decoupled from any accomplishment.

"Getting stuff" doesn't seem quite so fashionable, but I suspect that's because we're rich, we have most of the stuff we want anyhow, and we noticed that it wasn't making us happy enough. But next year's iPhone--that'll be the ultimate!

What doesn't seem to be so popular is writing a symphony or the next Moby Dick, or building cabinets that the Smithsonian displays. (Or becoming a saint, but that's never been popular) Accomplishment is harder than simple experience--is it also less popular? Accomplishment may be "what you will" but it involves a lot of grunt work or doing what other people want. And following rules--which conflicts with the "what you will" theme.

Maybe you can keep experiences longer than stuff, though dementia can steal those too, but at the end of the day you don't get to keep anything, unless you've invested with Someone in the resurrection business.

Can you tell I read Ecclesiastes recently?

Ownership


The 'Internet of Things' Is Sending Us Back to the Middle Ages
.

What Joshua means by that is that more and more in our lives is not owned but rented/licensed, and therefore controlled by someone else. The most dramatic example he gives is John Deere farm equipment--the embedded software is owned by them, and therefore the whole system must be repaired by them alone.

Yet the expansion of the internet of things seems to be bringing us back to something like that old feudal model, where people didn’t own the items they used every day. In this 21st-century version, companies are using intellectual property law – intended to protect ideas – to control physical objects consumers think they own.

My phone is a Samsung Galaxy. Google controls the operating system and the Google Apps that make an Android smartphone work well. Google licenses them to Samsung, which makes its own modification to the Android interface, and sublicenses the right to use my own phone to me – or at least that is the argument that Google and Samsung make. Samsung cuts deals with lots of software providers which want to take my data for their own use.

Have you noticed an uptick in businesses cutting customers off for their political persuasions? I get a whiff of Hell's Pavement (wikipedia) too. "I'm sorry Dave, I'm afraid I can't do that. You bought a Thermolux heater, and you know you're only supposed to buy P&D."


And everybody wants a revenue stream, not just a sale. Office 365 comes to mind here: You don't own it, you rent it. We use an older (licensed) version of Office on one machine, and LibreOffice on the rest.

Faithfulness

AVI is musing about measures of worth past and present. And future.

I was sure there was a chair behind me when I sat down. I trusted that bench to carry my weight. I trust that the gas station will take my cash in payment. I trust that if I push this button, the elevator will go up.

I trust that stores will be open when they say they will, and that the food inspectors keep the suppliers honest. I trust that the bus will go where the timetable says it will. I trust I don’t have to watch my back because my immediate neighbors will not try to kill me. (*)

These are important things for me.

For myself, I like "flexibility." There've been plenty of days when it would have been tempting to call in sick. And I have more interesting projects to work on than those I get paid to do.

We care a lot about faithfulness—in other people. Glen Campbell’s signature song Gentle on My Mind celebrated his lady’s faithfulness and his own "flexibility."

Not very fair, is it?

Some select people have succeeded in getting acclaim for their "flexibility," though usually under the name of "being true to him/her/itself." It seems that most of us just lose people's trust, though.


(*)About 2 blocks away I’m not so sure. If neighborhood and police reports are anything to go by.

The ENArchs

Class stratification in France: the ENA-rchs and French unions:
For all what the history books show, the French never actually had a Revolution. It is possible to go to Russia, and live there for years, and never see a trace of the old aristocracy in the state institutions or companies. There is a definite hierarchy in place, but it is not one based on class. In France, by contrast, it doesn’t take one long to figure out that the entire government and major corporations are dominated by an elite consisting of the old French aristocratic families (take a look at the names, and see how many have de in them) and the cream of the crop of the French grandes écoles:

and

And as with the government and the electorate, stuffing the upper echelons full of well-connected elites results in a huge disconnect between the management and the workers. For it is largely true that, no matter how hard one works and how brilliant one is, you will never surpass the chosen few from the grandes écoles in terms of promotion and prestige. For sure, many try, and considerable efforts are made by the company management to convince the ordinary folk that if they show sufficient compliance, obedience, and work themselves to death they will be admitted to the hallowed ranks of the chosen few. But in reality, they are being sold an absolute lie.

Anybody with experience in France care to comment?

Actions and words

"But what do you think? A man had two sons, and he came to the first and said, 'Son, go work today in the vineyard.' "And he answered, 'I will not'; but afterward he regretted it and went. "The man came to the second and said the same thing; and he answered, 'I will, sir'; but he did not go. "Which of the two did the will of his father?" They said, "The first."

If you haven't read Shannon Burns' essay on language and violence, do. Near the end is the story of Ricky at the recycling center.

Jesus said to them, "Truly I say to you that the tax collectors and prostitutes will get into the kingdom of God before you."

Ancient wars

A review of Dolly Parton’s Dixie Stampede wound up on my radar. The author (Aisha Harris) introduces it by comparing it to Medieval Times. I've been to the latter once: romanticized medieval culture, combat, and dining--not very closely related to anything SCA would put on. The real era often treated classes of luckless people very badly, and sometimes the conflicts involved things just as horrible as anything the 19'th century saw. But that was all 7-900 years ago, and the quarrels quit mattering long ago. Nobody but historians cares who was Duke of York in 1232, and we're apt to laugh at the differences between the warring sides--when we understand them at all. Not our oxen getting gored here...

In the American Civil War the North won, and by and large most folks in the North that I know don't give it a second thought anymore. Badger football is in Camp Randall stadium, and I doubt many fans realize the park memorializes a Union encampment/training ground. And when they do, they don't care. It's an ancient war. There are some customary attitudes one is supposed to have about it ("If this show were being performed in New York, he said, he’d think it was weird."), but little more. I can't speak for the South--I gather the hostility diminished over the years, and that in some circles there are customary attitudes one is supposed to have about it ("War was really about state's rights"--likely a big part of it for the rank and file, but definitely not true for the leaders). I've no idea how much emotion is invested in the war anymore.

But if the Dixie Stampede is any indication, where one of the pigs in the pig race is named for the iconic Lee, I suspect that there's a fair bit of "it's an ancient war" in the South too. What makes a glamorized Medieval Times-type amusement possible is that nobody deeply cares about the contest.

Aisha came to it as one for whom the themes of the Civil War were not ancient history. She found parts very awkward, sometimes tasteless or tone-deaf, and generally felt out of place. And she's right, of course(*). But I hope her children will be able to say "it's an ancient war." That might be a lot to hope for--maybe I should say her grandchildren.

The alternative to "it's an ancient war" is that new wars refer to the old in their laundry list of grievances. (Not that the old grievances matter as much as the new, but you want to show continuity in the villainy of your enemies.) That's not the road I want us going down.


(*) Although sometimes ... She complained that the "southerners" door label was light tan and the "northerners" was dark blue; this was tone-deaf. Um. If it had been reversed, would that have been better? I'd have thought the colors were a reference to the uniforms, not demography.

Babylonian "trig"

"Plimpton 322 predates Hipparchus by more than 1000 years," says Dr Wildberger. "It opens up new possibilities not just for modern mathematics research, but also for mathematics education. With Plimpton 322 we see a simpler, more accurate trigonometry that has clear advantages over our own."

When I read "However unlike today’s trigonometry, Babylonian mathematics used a base 60, or sexagesimal system, rather than the 10 which is used today. Because 60 is far easier to divide by three, experts studying the tablet, found that the calculations are far more accurate." I surmised that Sarah Knapton (Science Editor for the Telegraph) probably wouldn't know a sine if it hung blinking above the highway.

And it turns out the good Dr. Wildberger has a book to hawk. Said book is supposedly going to revolutionize the teaching of trig, apparently by using rational numbers and limits. (Don't reporters do any background checking anymore?)

Want a different view of the Plimpton tablet? It looks like a table of Pythagorean triples. Pythagorean triples are a fun topic that mathematicians have been working on for several thousand years now. I've played with them myself. The simplest one is the (3, 4, 5) triangle. The next is (5, 12, 13). There are an infinite number of them, and if it amused you (and apparently it amuses Dr Wildberger) you can get arbitrarily close to the shape of any right triangle with a Pythagorean triple triangle.

The traditional approach to trig links neatly with complex numbers and turns up smoothly in various branches of math. His scheme avoids some ambiguities with orientation, just as he claims, but also misses out on the connections. Poor choice.

In India, 1400 years ago, sine and cosine were approximated with parabolas, and I vaguely remember the idea being considerably older than that; so I'm not saying the Babylonians didn't do any trig. But this is not it.

Statues

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."

But what if the cause is not entirely worthy, or what if the man in the arena has some vices?

We, the pinnacle of moral development and the epitome of all virtues, weigh those vices and decide whether to acknowledge the other's achievements. We must not celebrate the poetry of this man because he was a thief and murderer, or the scientific achievements of that man because he wore the shirt his girlfriend gave him, or the courage and skill of a defeated enemy because you must have truth but never reconciliation. You can't celebrate a man who helped design a great experiment in liberty because he wasn't consistent.(*)

You've heard the complaints in the other direction too, haven't you? "You can't honor that Communist terrorist Nelson Mandela."

I don't fly a Confederate flag, nor want a statue of Lee in our neighborhood park. I get it that some people don't feel as though they were involved in any historical reconciliation. What gets up my nose is the envious insistence on our superiority and right to demand obedience to every single detail of today's rules.

Who died and made us God?


(*) You may have to fight the enemy because of his vices, but acknowledge his virtues--they probably make him a more dangerous enemy. You might even learn something from him.

Titles

I sometimes overlook the most obvious things, for the longest time. I must have read Voyage of the Dawn Treader fifty years ago, and I only just realized the sly title Lewis gave the Governor of the Lone Islands: "His Sufficiency." No majesty or excellence is claimed or aspired to; just "sufficient." Beautiful bureaucrat-ese.

Cat videos

In my youth I was a last-picked non-athlete, and I never got much into sports personally. In between other interests and a tendency to deprecate whatever was popular, I never got into sports vicariously.

And so, as a young adult, I didn't see much use in professional sports, and thought investing in a city team a terrible waste of money. Over time I started to notice that watching sports was one of the few civic bonding activities we had. Oh. Maybe this kind of entertainment serves a useful function after all...

Cat videos are a byword for triviality. But in seas of rancid virtue-signalling, perhaps they represent something we can bond on--at least a little. They aren't much at all, but every little bit helps. I won't sneer.

The marchers

It was predictable, and I'm not happy to have been right. We've had one flavor of political shock troops for a couple of years--pretty soon we'll have another; maybe more than two. I'd hoped we could keep it all in the past.

I wonder whose side the driver was on. As of this time I have to take every report with a helping of salt. I can think of four different scenarios for the driver without breaking a sweat--three of them fairly likely. All I know is that somebody is supposed to have been arrested. Update: He's alleged to have been seen with the first group of marchers. As feared.

One picture showed a close group of marchers, probably the same team, carrying confederate and nazi flags. (The old Confederacy lands supplied a lot of volunteers to fight the original Nazis.) I've no reason to doubt that "heritage not hate" is a real description of the motives of a lot of confederate flag wavers--and the combination of a symbol of resistance to central control carried with a symbol of totalitarian rule is more than a little ironic. Probably the pictured group were all nazis, and used the confederate flag as the symbol of racial supremacy it is for some people. Some of the other marchers were said to be racial separatists (not the same thing as supremacists, of course), and I've no notion yet of who the rest were, or even if they knew who all the other groups were. Somebody thought it was OK to have nazis tag along, though. Or wanna-be nazis.

Words are supposed to mean something. I've always been interested in history, and WWII was not that long ago when I was young. Nazis were still the symbol of the enemy, and everybody knew why. I hear horror stories that substantial fractions of today's graduates unable to tell what side England was on during WWII (or else who are pulling the pollster's leg--but I observe a fair amount of ignorance myself). What does "nazi" mean to them? Generic bad group? "I know, teacher! I know! It means Trump and anyone who voted for him!" Similarly, racist means you wonder out loud why we import foreigners to cheaply do the jobs you can't find anymore. It isn't even so much "May as well be hanged for sheep as for lamb" as that the distinctions are blurred.

When the powers-that-be claim that noticing certain problems makes you a swamp-dweller, some proportion of you will join the swamp-dwellers. Think of labor relations early last century. Publicly noticing problems got you called communist, and a lot of noticers joined the communist swamp-creatures.(*)

I suspect that too many people have long memories for the nazis to become a significant force again--certainly not under that name. But the attitudes may come back. We had those attitudes before, and though we've had a few generations in which white racism was suppressed, anything can happen--especially when the elite are alien and arbitrary. "Cling to those you can trust"--and you can't trust Pichai, or the Mizzou administration, or HR.

I used "you," but I, and I suspect most of my readers, are in the happy situation of having skills and education that mean we can comfortably ignore some of the problems, and that, knowing the history, we know the boundaries between the ordinary and the vile. I don't worry about the swamp-creatures--there usually aren't a lot of them. We protect free speech for good reason. I worry when people stop noticing the differences. God help us.


(*) National socialism is congruent to international socialism: totalitarian, the party is the most important thing, violent expansion, have to break a few eggs to create utopia... I regard Che Guevara shirts the same way I think of Martin Bormann shirts.

Blue and Green

I remember wondering once upon a time how it was that the Blue and Green parties got to be so all-encompassing: Religion, class, politics, sports--and probably other things the histories didn't record.

I think I get it now. If I were to find a MAGA hat and pay a visit to a few selected restaurants in Madison, I suspect service would be quite slow, and I might be rebuked for producing a "hostile environment." Virtue signaling your politics or social views in your business isn't ubiquitous, but is still very common. The new restaurant in the building we rent office space from made a point of emphasizing how much they supported Planned Parenthood--even before they opened. I think you can still eat at McD's without implicitly supporting any party, but stories about restaurants refusing to serve cops keep cropping up. Typically corporate comes down hard on the offenders, but clearly the impulse is there.

Has it always been like that? I seem to recall more overlap in interests when I was younger--but the Cubs and the Sox had (overall) different classes for fan bases(*), and my Better Half remembers a visit to Finn McCools to find the band was playing "If you hate the Queen of England clap your hands." (She got by with a visit to the ladies' room and some fractured German to a belligerent inquisitor.)

(*) It was explained to me that the class difference was a side effect of being located in different neighborhoods

Pets

In the Atlantic we find: "Pets don’t actually make people healthier, according to a new analysis. Ability to own a pet does." "The cat owners appeared healthier than people without pets, but the difference went away when the researchers factored in that the cat owners were likely to be healthy for other reasons, mostly bearing on socioeconomic status."

Of course, we want to keep an eye on this to make sure that the result is true. But if it is, what's going to happen to the Emotional Support Animal industry? I haven't seen their reaction yet, but let me guess: "The study doesn't address emotional issues, only deals with children ..."

Chastity of the Mind

It is tempting to embrace every story that comes along that flatters your tribe or besmirches your opponents. After all, the stories generally fit with what you know; build on knowledge you already have.

When you know the CIA is evil and has done unforgiveable things, stories of how they engineered Tolbert’s assassination or plotted 9/11 dovetail nicely with their record of villainy. Racists abound, so when 3 black churches burn in 2 weeks you know it means racist activity is on the rise. When you know the Clintons are corrupt and ruthless, the story that a man killed himself just before he was due to testify about them obviously tells of just another rub-out among many.

Be realistic. Soldiers won’t die if you don’t retweet that bon mot immediately, or repost that quotation of uncertain provenance. You’re not really in a hurry. You may like to think that hearts and minds wait trembling for your imprimatur on the news, but people who know you can probably already predict what you plan to say.

Instantly reposting stories that go down like such sweet morsels is just virtue signaling: your judgment must be profound since you have such noble friends and recognize such a vile and deceptive enemy!

Two words: Richard Jewell. Three words: Duke lacrosse case. Four words: Day care satanic abuse.

A good scientist looks at data that supports his model, and also looks for data that would contradict it. Until it is studied carefully, it is not good for either purpose.

The first reports are usually wrong. (Sometimes later ones are a cover-up, but not so often.) Let your conclusions be tentative, if you must draw any--wait a while and see what else develops.

Yes, I’ve been bitten by that kind of mistake too. It takes practice to reserve judgment.


“There’s a Bene Gesserit saying,” she said. “You have sayings for everything!” he protested. “You’ll like this one,” she said. “It goes: 'Do not count a human dead until you’ve seen his body. And even then you can make a mistake.'” From Dune by Frank Herbert


"Do you read the papers? Of course, you do. But do you read them as I read them? I rather doubt that you have come upon my system. ... I remember once when I lived in the Capital for a month and bought the paper fresh each day. I went wild with love, anger, irritation, frustration; all of the passions boiled in me. I was young. I exploded at everything I saw. But then I saw what I was doing: I was believing what I read. Have you noticed? You believe a paper printed on the very day you buy it? This has happened but only an hour ago, you think! It must be true... So I learned to stand back away and let the paper age and mellow. Back here, in Colonia, I saw the headlines diminish into nothing. The week-old paper - why, you can spit on it, if you wish.” From “And the rock cried out” by Ray Bradbury


“[John]: 'But I must think it is one or the other.'

[Reason]: 'By my father's soul, you must not - until you have some evidence. Can you not remain in doubt?'

[John]: 'I don't know that I have ever tried.'

[Reason]: 'You must learn to, if you are to come far with me. It is not hard to do it. In Eschropolis, indeed, it is impossible, for the people who live there have to give an opinion once a week or once a day, or else Mr. Mammon would soon cut off their food. But out here in the country you can walk all day and all the next day with an unanswered question in your head: you need never speak until you have made up your mind.” From The Pilgrim's Regress by C.S. Lewis

Old stories



Ngimun, Yidyam, and Barany are crater lakes in Australia. There's a story of how they came to be:

It is said that two newly-initiated men broke a taboo and angered the rainbow serpent Yamany, major spirit of the area ... As a result 'the camping-place began to change, the earth under the camp roaring like thunder. The wind started to blow down, as if a cyclone were coming. The camping-place began to twist and crack. While this was happening there was in the sky a red cloud, of a hue never seen before. The people tried to run from side to side but were swallowed by a crack which opened in the ground'....
.. After telling the myth, in 1964, the storyteller remarked that when this happened the country round the lakes was 'not jungle - just open scrub'. In 1968, a dated pollen diagram from the organic sediments of Lake Euramoo [Ngimun] by Peter Kershaw (1970) showed, rather surprisingly, that the rain forest in that area is only about 7,600 years old.

Some other stories refer to places that haven't been above water in 9000 years. "The stories tell of a river that entered the sea at what is now Fitzroy Island. The great gulf between today’s shoreline and the reef suggests that the stories tell of a time when seas were more than 200 feet lower than they are today, placing the story’s roots at as many as 12,600 years ago."

"In one of their stories, Ngurunderi chased his wives until they sought refuge by fleeing to Kangaroo Island—which they could do mostly by foot. Ngurunderi angrily rose the seas, turning the women into rocks that now jut out of the water between the island and the mainland. ... a time when seas were about 100 feet lower than they are today, which would date the story at 9,800 to 10,650 years ago."

The Aborigines apparently have some careful crosschecks to make sure stories don't change: some stories are sacred and must not be adapted by the storyteller. Some of these stories match the ancient landscape nicely--the settings match.

What doesn't quite match is the action. OK, the volcano erupting is a pretty good description of what you might see. But the ocean levels weren't supposed to rise that fast. Stories of a woman crawling along dragging the water after her, or of Ngurunderi angrily raising the sea, are dramatic. That's either something that happens within a human lifetime, or something made dramatic by foreshortening. I'm not sure what would jump a shoreline 20 meters in a human lifetime: Lake Missoula draining won't do it (I estimated about 1mm rise from that). That amount of water draining off the glaciers that fast ought to have done dramatic erosion which we don't see. Great glaciers deciding to up stakes and slip-n-slide to the ocean would have turned the southern US into a Canadian Shield. Could 20 meters happen in a hundred years? My geologic skills aren't good enough for me to say.

That leaves foreshortening. What does that mean in practice? Cast back a few millennia. Stories from 1000, 200, 100 years ago illustrated landscape changes that needed to be explained. Assuming the rock formations were already regarded as women, somebody then synthesized the revised story from the old ones. Although this isn't the sort of thing they do, remember? Otherwise how would the details have stayed intact? Which leaves the option that the story was created at that time. It had to start sometime, of course. But the faster the sea level rise was, the less time was required to keep the stories intact, and the if they didn't need to keep them intact long, the more flexibility ancient the story-tellers/memorisers could have had compared to the modern ones.

UPDATE: I forgot about Lake Agassiz, which raised sea levels several meters when it drained in O(8200) years ago, and presumably also the earlier drainages. Not quite 20 meters, but if as supposed it happened over a few decades, people would certainly notice.

Turning Points: Decisive Moments in the History of Christianity by Mark A Noll

Executive summary: The before and after for a baker's dozen important moments in Christian history. Read it.

  1. The Church Pushed Out On Its Own: The Fall of Jerusalem (70)
  2. Realities of Empire: The Council of Nicaea (325)
  3. Doctrine, Politics, and Life in the Word: The Council of Chalcedon (451)
  4. The Monastic Rescue of the Church: Benedict’s Rule (530)
  5. The Culmination of Christendom: The Coronation of Charlemagne (800)
  6. Division between East and West: The Great Schism (1054)
  7. The Beginnings of Protestantism: The Diet of Worms (1521)
  8. A New Europe: The English Act of Supremacy (1534)
  9. Catholic Reform and Worldwide Outreach: The Founding of the Jesuits (1540)
  10. The New Piety: The Conversion of the Wesleys (1738)
  11. Discontents of the Modern West: The French Revolution (1789)
  12. A Faith for All the World: The Edinburgh Missionary Conference (1910)
  13. Mobilizing for the Future: The Second Vatican Council and the Lausanne Congress on World Evangelization (1965, 1974)

Obviously many of these (e.g. The Great Schism) are merely marker dates for larger and longer events. And sometimes the motivating events (e.g. The French Revolution) are external to the Church, but have an impact on it.

The approach gives a convenient framework for covering almost all of Church history. Each chapter's introduction includes a characteristic hymn from the era, and ends with a characteristic prayer. The book is quite readable. The author does his level best to be accurate and empathetic.

Read it.

Olds

I wonder if there is a market for a journal reporting "the rest of the story?"

The news feed tells you what is supposedly happening right now, but anybody with an attention span longer than a day knows that those stories are almost invariably incomplete at best, and often simply wrong. I exclude celebrity gossip stories from "news."

Call it The Follow-up Gazette with the motto All the things we found out later.

  • After the drive-by shooting the police woke up everybody on the block to find out if you had heard anything: One kid was playing with his parent's revolver and accidentally shot his buddy, and they made up the "drive-by" story to try to deflect blame. You didn't hear anything because the shot was indoors.
  • The man who claimed he "just said hello to the sleeping homeless man" when suddenly the homeless man attacked him: He is sticking to his story, but nobody believes that was all he said. The homeless man was charged with battery.
  • A report that claimed that the brains of men and women are indistinguishable received a lot of admiring attention. Peers believe the authors should not be allowed out in public without a minder.
  • The Badger Ammunition facility was declared excess and slated, with great fanfare, for cleanup and transfer to other agencies. This is still going on. Cleanup takes years, and so do negotiations. Ho Chunk wants part of the land but the BIA is not on the same page with them.
  • A was standing in front of his house in his underwear when B walked up to him and shot him dead. B was charged with murder. At the trial he was found not guilty. The defense had argued that he shot A because he had reason to fear for his life.
  • Yesterday we reported that Vlad won a blue Lada in a lottery on Tuesday. We have some minor corrections: It was not blue it was green; it was not Vlad but Oleg; it was not a Lada but a bicycle; it was not Tuesday but Thursday; and he did not win it, he stole it. Aside from that the story is substantially correct. Purloined from You Call This Living?

I took a little liberty with one of the above stories, in which I don't know the complete outcome.

Making of the news

ChicagoBoyz referred readers to a story about the next stage up from press releases: story generators for hire.
On Wednesday, three major news organization published variations of the same story—about the line of succession to the Saudi throne. It seems that in June the son of King Salman, Mohammed Bin Salman, muscled his cousin Mohammed Bin Nayef out of the way to become the Crown Prince and next in line.

It’s a juicy narrative with lots of insider-y details about Saudi power politics, drug addiction, and the ambitions of a large and very wealthy family, but the most salient fact is that the New York Times, Wall Street Journal, and Reuters published what was essentially the same story, with minor variations, on the same day—not a breaking news story, but an investigative feature.

In other words, these media organizations were used as part of an information campaign targeting Riyadh, for as yet unknown reasons.

...

On Wednesday, the Times reported that Gen. Abdulaziz al-Huwairini had been put under house arrest by a faction loyal to Mohammed Bin Salman. On Thursday, the Times reported that he was in fact named head of a government body overseeing domestic security and counterterrorism issues.

We've known for years that some reporters simply regurgitate press releases, and that said press releases are often heavily spun ("I say it's spinnage, and I say the hell with it!"). This sounds like a simple expansion of the process.

I've no reason to doubt that there are still plenty of investigators out there--though not nearly as many professionals as there used to be. Unfortunately there's not always an easy way to tell an amateur investigator from a spinner, or worse, a fabricator. And not always an easy way to tell whether the professionals are on the mark either--except by waiting.

Crime stories and otherwise

Naked Manitowoc man catches fire after being tased. OK, it was just his beard and chest hair: the taser hit a lighter he was carrying.

Man Who Pushed Stranger in Path of Train Acquitted of Murder. Sounds pretty dreadful, on the face of it: one man pushed another off the platform and then ran, while people stood around and took movies of them both (a tabloid journalist claimed he was using his flash to warn the oncoming train--and a Nigerian prince wants me to handle his finances). Those people taking movies were the reason Davis was acquitted: the movies proved he pushed Han in self defense. Han was drunk and belligerent--I'd guess nobody helped him out because nobody wanted him attacking them and dragging them onto the tracks with him. With a train coming, you aren't going to get much enthusiasm for collecting a group to join him down there and lift him out.

Funny how much stories can differ from the headlines when you get more of the facts.

Have you seen this warning?

Proposition 65 WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

I remember buying some textured paint and discovering that sand was supposed to cause cancer. I assume they meant if I sanded the dry paint off without using a breathing mask then maybe some of the silica would find its way into my lungs along with all the other paint crud.

Order

You can't pin down where an electron is around an atom. You can say where it probably is, but no more. But it is a predictable "chaos:" random but reliable.

In a cloud of molecules some collide, and perhaps interact. Their trajectories are impossible to calculate, and you can't say which oxygen will combine with which hydrogen. It may take a lot of bouncing around to get all the bits combined. But looking at the bigger picture, you can say the oxygen and hydrogen reliably burn to form water.

There are so many molecules in a single cc of air that all the computers on Earth can't predict the trajectories in detail. It looks wild and chaotic on the microscopic scale, but on our scale PV=nRT is a very simple and useful equation.

Inside an amoeba complicated molecules move this way and that with no obvious pattern, but widen the view a bit and you see them breaking down the lump the amoeba engulfed. Widen the view some more and you see an active creature moving about and eating and reproducing.

The plant scatters seeds randomly, and hundreds of other plants compete for the same space. A cow mashes some into the mud. A falling tree obliterates another region. But the big picture shows a green meadow--with its own kind of order. And it's a robust order--or antifragile, if you prefer.

Economies seem to work similarly: disorder at one level, smoothed out to much more orderly at larger scales.

Sometimes my life seems to consist of reacting to one chaotic crisis after another, but at the end of the year it has had a flavor different from somebody else's reacting to chaotic crises.

A crystal is very orderly. Kind of limited, though. Chaos--the building material for order?

Names In Memoriam

Sometimes a place gets a name because of something that happened there, or that used to be there.

We haven't heard the spring frogs since Nature's Preserve Office Park was built, and it looks like they cut down the trees and scraped off the topsoil to build the Wood Farm development.

Venus atmosphere

"The measurements showed that the temperature near the surface was hot compared to the temperature at an altitude of seven kilometers," Schubert said. "The atmosphere shouldn't have been in that state; it was highly unstable. Whenever you have very hot material underlying a layer of fluid, the fluid tends to turn over." If you have access, the paper is here.

It isn't easy to study Venus. The hot acid atmosphere dissolves space probes. Only one probe's temperature gauges survived all the way to the surface, and even that probe didn't last long. The article says that the pressure, temperature, and composition of the Venusian atmosphere could make it a supercritical fluid, acting like both a gas and a liquid. I don't know if it could act like either alternately, though that would be cool. Did anybody else read Close to Critical?

A terrestrial measurement at much lower temperatures suggests that the gases in the atmosphere might separate out under those conditions, leaving more of the dense CO2 at the bottom, even if the bottom level is at higher temperature. (The calculation of what sort of temperature distribution Venus should have is hard, and I won't attempt it.) Extrapolating to conditions on Venus is . . . um . . . speculative. As the article says, they've two choices: try another Venus probe or try to reproduce Venus conditions in the lab. The lab is probably cheaper.

Why would this be important enough to sort out? The paper notes that there would be much less nitrogen in the atmosphere of Venus if it were excluded from the lowest, most dense layer. And that could influence how we understand both the formation and evolution of the planet. It could also inform our understanding of a variety of other planets, where gases exist under similarly extreme conditions.

That's the sort of stuff that goes in the grant proposal. What's the real reason for trying to study it? It's weird and cool.

Plus, let's face it—it would be pretty cool to have something so bizarre happening on a planet that could be Earth's twin if it were elsewhere in the Solar System.

Yes, I know it is odd to think of Venus' atmosphere as "cool."

Gain the whole world and lose his own soul

Does it strike you as odd that solipsism is so popular these days? References to "my truth" or the assertion (usually only implicit) that "How I perceive myself is who I am" turn up with disconcerting frequency.

I wonder if part of this is a reaction to "scientific claims" about human nature. When you're told that you do X because of Y, or think Z because of T, you start to feel like a puppet. If your mind is just rationalizing what you've already chosen, you're kidding yourself, so how can you communicate with anyone else? Or can I even cogito?

If you try to shoehorn human experience and communication inside the universe bounded by sense perception and what can be tangibly measured, there's not much room for a "you," and still less for communion. In a way you "gain the whole world" in terms of what power the approach can give, but you lose your soul. That's not universally popular—even Faust regretted the bargain.

Of course you know better, but the these days default parameters of the debate are Descartes': even if you're not a puppet, you still wind up with an incommunicable reality.

There’s another way, of course—or two, or three. One way says that statements about our nature refer to things that "ought" or "ought not." "Ought" is not something you can derive from science, and if you propose to think only in categories of sense-perception and tangible measurements, you're cut off from that. You may find the oughts inconvenient sometimes (like me), but you are free to do the oughts or not. This leaves room for "you," for communion, and purpose—and a creator.

That last item can be frightening. Suppose my creator has different priorities and different ideas about my nature. Will conforming to my creator lose me myself?

Christianity says "just the opposite," but you can see how the prospect would look to someone who believes their nature is their perception of it, malleable by their choice.

The Fate of Africa by Martin Meredith

A History of 50 Years of Independence

The book treats all of Africa, including Arab and Egyptian regions. It’s about a dozen years old now, and things have not gotten better. It is too early to say if the partition of Sudan will help—I hope so. Not every place went to hell, but enough did to show patterns.

Some stories differ dramatically from the others. The history of Algeria makes grim reading. South Africa seemed to show a spot of hope, but the intervening years since the book was published brought little encouragement.

Iron smelting and forging technology spread through Africa long ago, but the various industrial revolutions passed by Sub-Saharan Africa—until the last one, which spread imperial Europe everywhere. (It seems odd, because fairly simple constructions like water mills can send your iron smelting temperatures much higher, to give you more iron at once, and of better quality. Persian windmills ground grain easily—it wouldn’t have been hard to duplicate. There was trade across the Sahara, and across the Red Sea and Indian Ocean. A puzzlement. But perhaps the crops in some areas aren’t as suited to grinding. At any rate...)

What happened after independence?

The imperial powers infamously divided everything up with little regard for tribal or language affinities, except insofar as they helped them govern. Since they preferred to concentrate trade and industry in their own hands (and all the good land), at independence there weren’t many paths to success. “Forced labor” shows up repeatedly in the history—and that doesn’t mean desk jobs or entrepreneurs.

Though Africa has had large kingdoms and even empires before, recent history was all about the European nation-state model—and each new country needed its own government. Participation in which would represent one of the very few paths to success. Moslems often talk about the Ummah and deprecate nations, but in practice they like running the local show themselves just as much as the infidels do. So, the areas had themselves nation-states.

The imperial/global economy defined success and wealth in terms of consumption of Western goods, and offered tantalizing stuff to consume. More temptation, that you need a revenue stream to participate in.

Despite an initial bonding of “us against the imperials” a man’s loyalty was not to a country but to his family, tribe, and hangers-on. And you cannot rely on the support of your tribe if you are stingy.

What followed from this was: mismanagement from the get-go thanks to a lack of managers; concentration of power and ambition in the central government—universal control nominally to have disparate tribes work together for a common goal but in practice for rent-seeking; pretty much universal corruption; “meet the new boss, same as the old boss”—just from a neighboring black tribe instead of a white one. Making a nation a “democracy” merely changed the emphases, and didn’t generally have any effect on the “my tribe in power” corruption.

Some leaders took the European ideologies of socialism and Marxism seriously, as opposed to as bargaining chips in getting aid. Their subjects generally paid dearly for the experiments.

A lot of the details in The Fate of Africa weren’t covered in the news of the day: sometimes out of fear, sometimes because of entrenched lies (e.g. Rwanda genocide), and sometimes because Western news teams couldn’t be bothered. Quite a few people look very different (some worse, quite a few better) than they were originally reported. Lots of heroes had feet of clay, and unfortunately circumstances often brought out the flaws in a big way.

Read the book if you’ve any interest in Africa.

Because there is rarely a sense of nationhood, the obvious path to organic development and to reducing friction would seem to be through a different model of government, with federated statelets based on tribal affiliation, with a relatively weak central government. (Sort of Swiss style) Unfortunately this tends to leave you at the mercy of neighbors that cultivate a large army (African leaders are no more moral than those anywhere else when it comes to a neighbor’s easily stolen stuff). The only way to guarantee the integrity of such federations, at least at first, is for external parties to guarantee them. France has a record of this, and it usually works OK, though there’s a price to pay and they sometimes misfire very badly (e.g. Rwanda).

But—how do you get there from here? You don’t. The local powers-that-be aren’t going to give up their power and iron rice bowls, and (e.g.) European powers have no great interest in enforcing somebody else’s borders for no benefit to themselves.

What could help? The author suggests that industrial countries could cut back on farm supports, and let African exporters sell renewable crops and not just raw materials. That seems reasonable, though politically complicated. The Cold War is mostly over, and the proxy conflicts are done--that helps too.

I’d suggest learning a little more about the full situation before we try to throw food aid at a famine—often that makes the long-term situation worse as it ruins local farmers who tried to produce a surplus, and famines tend to be political creations anyway. And funding tiny projects, not big tempting cash cows (though lots of tiny projects get to be very expensive, since you need more people on the ground to investigate). The expectation is that if you get a degree you deserve to get a government job—that expectation has to change. Define educational objectives and focus on those, with the goal that the farmer will be a citizen farmer, the clerk a citizen clerk, and that education will not be a job training program.

All easier to say than do... The book does not depict Africans as puppets, but as their own agents, working with the environment they found themselves in, or which they helped create. The important changes have to come from the African groups; they can't be imposed. And some will turn out better than others.

Roman cement

Why modern mortar crumbles, but Roman concrete lasts millennia:
Al-tobermorite, long known to give Roman concrete its strength, can be made in the lab, but it’s very difficult to incorporate it in concrete. But the researchers found that when seawater percolates through a cement matrix, it reacts with volcanic ash and crystals to form Al-tobermorite and a porous mineral called phillipsite, they write today in American Mineralogist. So will you be seeing stronger piers and breakwaters anytime soon? Because both minerals take centuries to strengthen concrete, modern scientists are still working on recreating a modern version of Roman cement.

An older view article said:

It's the reaction that occurs between the lime and the volcanic material that produces the stronger concrete, the researchers found. As the concrete hardened, strätlingite crystals formed in spaces around the sand and the volcanic gravel, making the structure stronger.

Can we do the same? Apparently some varieties of fly ash have similar composition to volcanic ash. Maybe the Three Gorges Dam will luck out.

Dana Loesch

I don't keep up with these things, but a recent NRA ad was pointed out to me. I gather that Dana Loesch is or was a NRA representative. "I'm freedom's safest place." Urk.

Not quite.

Some of the things in the ad refer to significant problems. The brownshirts of anti-fa have had malign impact in places like Berkeley, and even here in Madison they allegedly ambushed and attacked a man coming out of a restaurant a block away from me, presumably "pour encourager les autres" (I've eaten at that restaurant a number of times). BLM has participated in and inspired some violent riots. Here in Madison their protest was peaceful. A startling proportion of the movers and shakers in media and arts seem to have started believing their own press releases, and consider Trump a racist and fascist and nazi and what-all else: and the rhetoric is often explicitly violent. But aside from Hodgkinson I don't see a lot of action based on it.

The dangers tend to be concentrated in a few places (I'm not forgetting that attack a block away!), and the rest of the country is calmer. The NRA has always been a bit on the shrill side, (like all such political organizations) but this is over the top. The violence problem in this town isn't from the political street thugs, but the Milwaukee and Chicago gangsters.

I've been predicting that if the existing political street thugs weren't dealt with, we'd start to get right- and center- political gangs as well, and that that wasn't going to end well. It sounds as though the NRA isn't waiting, but the call isn't explicit--plausible deniability. I'd be interested in seeing if Dana is still a representative next week. I hope not.

Heisenberg's chimps

"Chimpanzees in Uganda may have changed their hunting strategy in response to being watched by scientists."
"Sonso" chimps hunt in small groups for colobus monkeys, while those from the "Waibira" troop hunt solo and catch "whatever they can get their hands on".

...

Biologists who have followed and studied these animals for years think that work may have disturbed the group hunting that seems key to chasing and catching colobus monkeys.

I trust nobody is surprised. You'd probably change your hunting methods if you were being watched by chimps. And I've a strong suspicion that the spear-wielding chimps learned from watching people.

Research can be tough sometimes. And that's when you're not dealing with people. (The author of the latter was one of the Unibomber's targets. "McConnell originally published satirical articles alongside serious scientific articles in the Journal of Biological Psychology but received complaints that it was difficult if not impossible to tell which was which.")

Stowing wheelchairs

I was talking this morning with a man who’d sustained a temporary injury that meant that although he could walk a little, and drive, he had to use a wheelchair most of the time. He’d fallen. He fell again while trying to store his wheelchair, and in consequence had to rely on other people to help him drive around.

Perhaps that’s actually a good thing, but I wondered if there were ways to make it possible for someone semi-wheelchair bound to drive by themselves.

If he uses a collapsible wheelchair, it might be.

The most obvious approach is to have a four-door sedan in which the front door is hinged, as usual, on the front, and the rear door hinged on the rear. Wheel up, open both doors, sit in the driver’s seat, fold the wheelchair and shove it into the back seat area, then close the doors and drive away. Reverse the procedure to get out.

The problem with that is that remounting a car door would take fairly massive and expensive modifications—probably of order of the cost of a used wheelchair van. (Which aren’t cheap.)

Another possibility is a roof-mounted mechanism using a swing-out arm. It would probably have to be motorized, but that could be arranged.

  1. Wheel up to car, open door, and have swing-out arm open out
  2. Sit in car and fold up wheelchair
  3. Lower and attach the upper attachment cables to the wheelchair.
  4. Raise the wheelchair to mid-station, and lower and attach the lower attachment cables to it
  5. Raise the wheelchair the rest of the way
  6. Have the mechanism turn the wheelchair sideways
  7. Rotate the swing-arm back over the car

Reverse this to get out of the car.

This doesn’t sound like a very cheap prospect either, and mounting it solidly to the roof of a car sounds difficult—though easier than trying to change the frame. It doesn’t sound like something you would rent for a few months.

Or you could strap a walker to the back of the wheelchair, and unlimber that when you need to store the wheelchair. You might need a hooked rod as well to help you get the wheelchair in and out, of course. A lot cheaper...

Mismatch somehow

I've always liked climbing on things (Right knee registers a dissenting opinion), but never liked heights. A very early memory is of happily clambering partway up a slide and then realizing "Oh crud." (FWIW airplane travel doesn't bother me, and it doesn't matter much whether it is me or someone dear to me near the edge. Or near the foreshortened slope.)

I'm not sure how to square that circle.


Devil's Lake is a beautiful park, even with ominous clouds heading over the bluffs in your direction. We figured that it was going to be super-crowded and so parked at Steinke Basin and took a long access road into the park, which brought us in at the top of the bluff without having to climb or fight traffic. I'm starting to get better at tunnel vision, though that defeats the purpose of taking the bluff trails. (When I walk and stare at something off to one side, I drift.)

When we got to the Devil's Doorway trail we rested and watched our guests, teens, families with little kids, and a one-eyed lady with a cane climb down to see the Devil's Doorway. Felt a little silly.

Further along the path, a Spanish family said someone had fallen. None of us was trained or equipped, so we stayed away to give the pros room, and about 20 minutes later a couple of fire rescue vehicles appeared, and some time later an ambulance showed up at Steinke--it couldn't navigate the paths and waited for the call that the others were bringing the patient. We didn't learn any details, but fallers are usually the cliff-climbers, not the average path-walkers.

Physics and econ

RCS has a link today to a Guardian story: "Why I left physics for economics. I recently decided to abandon the rules that govern nature for the rules that govern people and markets: economics. Why would I do such a thing?"

Short version: work in physics is hard to find and unstable (which means jerking your family around--some of us value stability, contra Zuckerberg's values). Econ has interesting patterns and rules to be discovered, just like plasma physics.

Do other people remember quants on Wall Street? True, that was GIGO and most of the blame lies with screwed-up economic models the quants were given. Still, I'd look twice. Maybe three times.

It seems that the quant jobs weren't all they were cracked up to be. (One of the warnings in that last link is that living near the super-rich and seeing shops devoted to things you'll never afford makes even well-off people feel poor. Wealth is relative--who knew?)

Baseball matches for charity

I hadn't known that there was a charity baseball game between legislators in DC. Nice idea.

I wonder if one could promote a little more amity with similar baseball charity competitions among the three letter agencies. True, some of them are large enough to support whole farm systems as well.

Can you find fitting names?

The FDA Stoners, the CIA Moles, the Dept of Education Hickory Sticks, the HUD Trogolodytes, the NSF Perpetual Motioneers, the Dept of Energy Alchemists, the DOD Atlatls, the DOJ Yardbirds, the DOS Woosters ...

Close

We were retracing our steps along the lower level of the Lime Kiln trail at High Cliff State Park, about ready to head home for the day. (It isn't that high a cliff, but it is part of the Niagara escarpment.) We started hearing a crackling and crashing, as though rocks were starting to break loose on the slope above us. After a second or two we saw that a large tree was falling towards us--maybe a little ahead, maybe not. We went elsewhere quickly.

The falling tree snapped off another tree on the way down, and made quite a crash when it hit.

The crown sat six inches from the edge of the path.

It saps a little of the drama of the incident to realize that we could have just kept strolling along and been perfectly safe...

Paradox Men by Charles Harness

When I was about 8 or 9 I discovered Dad's Ace Double science fiction books. He left a lot of books behind, but one of those he took with us looked fascinating, and I liked Dome Around America. The book on the other side looked a lot harder to get into, and I didn't actually read it for a few more years.

When I did tackle Charles Harness' The Paradox Men, I loved it. Williamson's Dome I reread once, but it wasn't his best work by a long shot. Paradox Men, on the other hand...

I re-read Paradox this evening, and know enough physics and physiology now to have to force a lot of suspension of disbelief, but the liberties taken aren't for scenery--they drive the plot, which is fast and neatly concluded and as enjoyable as I remembered. Who, and what, is Alar? BTW, the later slightly edited edition is cleaner than the version I remember from 40+ years ago.

Other people have done similar things since (and Frank Herbert borrowed his shields for Dune), but it's a nice un-ironic read.

So if you're willing to forget real physics and physiology for a spell, read it.

Elk learning

Elk learn not just hunting season, but what kinds of weapons they're being hunted with--and adjust accordingly.
During bow season, they used difficult terrain more – making things tricky for bow hunters, who need to get much closer to their prey than those who use rifles. And during rifle season, the elk stayed further away from roads, where hunters might spot them.

The article ends with a suggestion that this might be useful in land management--a little hunting close by farms might encourage elk to take their custom elsewhere.

I wonder if this works for deer.

ViewMaster question

Mattel has contracted out production of this classic to The Bridge Direct, which presumably means their research budget is $0.00. Unfortunately.

I sent the firm an email, but wonder if anybody has seen ViewMaster reels made of plastic instead of cardboard?

Humidity and termites are not nice to cardboard, and it turns out these things are common in some parts of Africa which might benefit from having cheap tools for displaying images of geological features (and meteorological, etc) to children who don't have access to TV or travel. (The students would have to share, obviously.)

So: has anybody seen more durable reels than the ones I remember from childhood? Or from 25 years ago when I asked them for information as part of an outreach proposal for Fermilab. It never got off the ground.

Education in Africa, one data point

I'm doing a bit of research on tools for science education in elementary school in Africa.

From the Guardian, 2012

The hypothesis In the 1990s, a Dutch development charity called International Christelijk Steunfonds decided to fund a programme to support education in Kenya. Previous research had suggested that providing African children with textbooks that they could not normally afford might improve their exam results, so the charity paid for 25 schools to receive sets of English, science and maths books. The charity, however, didn't just provide the books. It decided to run an experiment.

The experiment As Tim Harford describes in his book Adapt, ICS asked the Kenyan government not to select 25 schools that would receive the books, but to identify 100 schools that would be equally suitable. From these, 25 were selected at random. The books were delivered and exam results at the 25 intervention schools compared with those from the 75 similar schools without the extra teaching resources.

The textbooks, it turned out, made very little difference. ICS then tried another intervention – illustrated teaching flip-charts – in a similar randomised trial. Again, there was no significant effect.

=So the charity tried a third approach, funding treatment for intestinal worms. This time, the trial followed a staggered design: 25 random schools received the treatment immediately, 25 after two years, and another 25 two years after that. This time, there was clear evidence: de-worming children unequivocally improved their learning, probably thanks to improved nutrition.

The more things change

I don't believe I can describe political discourse better than Twain.

Silence

I caught part of an interview with a chaplain who wrote about hospice chaplains. I didn't expect the emphasis on silence.

She seemed to be saying that guests who were silent could give the patient permission to be silent also--to be silent with God and their life.

There's a time for goodbyes and making sure things aren't forgotten, and especially for trying to mend fences before it is too late.

Dave Barry wrote a moving column about his father's death, and his disappointment that the last words seemed so trivial. In the nature of things, the time of dying is generally not suited for long deep talks.

But silence means something. On the one hand we know of "the silent treatment" and the "I'm too busy to be bothered," but on the other hand there's the "The words have all been said already, and we can let their meaning echo through our time together."

It's easy to think of silence as like the empty spaces in one of the old Japanese prints. The emptiness has a shape and a meaning there, given it by the lines. But perhaps silence can also be a positive thing in its own right, a sign of a different kind of communication. "Be still and know ...?"

It turns out silence is hard to come by. Over the years I've met several people who talked as though they feared that they would stop existing if they stopped talking. As I sit here I hear the highway, the turtle tank filter, a ball game broadcast in another room--but all these are easier to quiet than the "drunken monkey." One has to try. "Be still and know ..."

Blast from the past

I don't know why I thought of Bernard Goetz this evening, but the next thing that came to mind was "What happened to the four?"

Fortunately somebody else asked that question already, and the answer in this article matches other stories elsewhere.

Apparently the NYT report about sharpened screwdrivers was wrong--they had some for a planned theft, but not sharpened. And the claim that they were innocent panhandlers was contradicted by one of the four, who said they thought he was easy prey. And the attitude of Ramseur at the trial was so nasty that his testimony was stricken, and some think that Goetz was acquitted of most charges because of Ramseur. And though Goetz shot 5 times, one bullet missed, which was the basis for a reckless endangerment charge.

Cabey was partly paralyzed and possibly brain damaged--his family won a $43M judgment against Goetz which they have yet to collect. Ramseur went to prison for 25 years for a vicious rape, and apparently killed himself a year after getting out (on the anniversary of the shooting). Allen went to prison for a couple of robberies, and there's nothing that comes up since 1995. Canty indulged in a number of minor offenses, and was arrested but not charged for robbery and assault of his common-law wife in 1996.

I assume that Allen and Canty are still alive--either's death would be an instant and easy news story, and I didn't find one. If so, the 20 years since the last reported interaction with the law is a good sign.

How the mighty are fallen!

Scientific American published an article on plans to recall the brain-dead to life.
First there’s the injection of stem cells isolated from the individual’s own fat or blood. Second, there’s a peptide formula injected into the spinal cord, purported to help nurture new neurons’ growth. ... Third, there’s a regimen of nerve stimulation and laser therapy over 15 days to spur the neurons to form connections. Researchers will look to behavior and EEG for signs that the treatment is working.

The article gives voice to a number of skeptics. Count me among their number. This is too silly for words--"Your laptop's hard drive isn't working? I'll fix it with superglue!"

This isn't the same Scientific American magazine I grew up with.

Featherless biped

Oops. T Rex skin seems cheerfully feather-free. Ditto other tyrannosaurs. They argue that large dinosaurs would, like large mammals, have lost any extra covering that might make them overheat. Or, maybe they never had any? Maybe the putative feathery ancestors were weird uncles and not grandfathers of the T Rex line.
None of the scales are as big as what you see on the back of a crocodile, but they are similar to the scales along a croc’s flank. I suppose tyrannosaur hide would make for a nice set of luggage.

Goldfish swallowing

Nearly half of American children spend at least 16 years in school.

School is a pretty artificial environment. There are fixed courses of study that don’t necessarily bear on what is going on (or will happen!) in your life, and within a course there are arbitrary projects and questions designed to make sure you master the material. When done, typically you won’t care 2 cents about them—and neither will anyone else. They aren’t intrinsically significant.

But we want to do something significant; we want to stand out from the crowd somehow. In school, there are some problems with this.

  • Athletics take lots of uncomfortable work, and in the end you may not stand out much compared to those with natural talent.
  • Math can be hard when you get beyond the elementary branches, and the advanced branches need talent.
  • Music takes practice, and the conductor usually objects to one musician in an orchestra standing out from the rest, unless the score calls for it.
  • Something dramatic and goofy, like phone booth stuffing? Problem is, people might laugh at you.
  • A job, or marriage? The system is designed to make it harder to do schooling when you work or raise a family. Twain said that he never let his schooling get in the way of his education; we need to make sure that schooling doesn't get in the way of our lives. That means some re-design...
  • Student government? The local stakes are normally dramatically lower than they are in state or national government, and that irks. But perhaps if you can expand the scope, and try out Utopian plans?
  • Being a prophet? If you’re an approved type, that can be a good gig—you get to indulge in lots of yelling and denunciation, and since you’re approved you don’t have to worry about the usual troubles real prophets have.

Tangible

At Ricks by a graded road near our house lay a four foot pond. It bred mosquitoes, of course, but then tadpoles appeared, which seemed to take care of the larvae. The attraction of such a feature in the landscape should be obvious.

We tried slinging in dirt clods and rocks to see who could make the biggest splash. The tadpoles usually wriggled back to the pond, though not always—and that meant flies, which were annoying.

A couple of us tried to throw in a quite substantial quartz rock. Alas, it was so heavy that we couldn’t give it any speed, so it made more of a minor tsunami than a splash. It sank in the mud, leaving only a pyramid an inch above the water.

Next year the pond had filled in, and was now just a minor depression with a bit of quartz sticking out of the dirt.

I saw it again a few years ago. Re-grading had covered everything over, but I knew where it had been, and where the rock still was.

The quartz boulders in the field beyond that were so sharp edged when we used to jump on them were weathered and a little overgrown, and the trees and logs were long gone, but I still remembered where they had been.

Paths we explored, the field where we played 5-man football (It is hard to field two teams with only 5 players), the route the horse took around my grandfather’s house when he borrowed a placid horse so we could ride, where the persimmons that nobody really wanted grew—I can point to all these things.

I think I spent more time reading books than playing outdoors, and books are tangible too. For a while I was in another world, and then all evaporated when it ended. Almost all, there’s a residue in the imagination (what you immerse yourself in affects you). But I could still point to the book and say “I read that.”

Our Youngest Daughter dislikes e-books intensely, even when it is the only way to read some out-of-print work, saying that there is no substitute for the tangible thing in her hands. (Most of the articles and reports I deal with are never printed out, FWIW.)

I started down this path when I started wondering what difference it made for a generation to spend leisure with intangible amusements: video games in particular, though I suppose you could expand that into videos and ubiquitous music. I think the latter are more passive, though: books and the games require something from you to keep them going. It seems as though people don’t make their own music as much as they used to—maybe competing with the ubiquitous pros is too hard. I should try counting how many people seem to be singing in the car.

I have to speak only from observation about video games: I never got into them enough to get the dexterity to enjoy them, and at this stage of my life I don’t care to invest my limited time in them. But they seem especially ephemeral. Maybe you saved the game at some point, and maybe the scores are saved for a while, but close it down and where is it? Your life has fewer tangible markers for things you’ve done.

I wrote software for DAQ, hardware diagnostics, processing and filtering, and analysis—things people needed at the time. They were ephemeral too, but the fact of their service to the team remains. True, the result is a few journal articles, some of which nobody reads anymore. But the help was something real, though intangible. So maybe I should widen my question a bit, but … maybe next time.

Perhaps the best way to say it is that I feel more grounded, maybe a bit more real, when I can point to something and say “I made that,” or “I helped that person,” or “I was there.” Maybe that’s just me, and maybe very few people are as deeply into the ephemeral as advertised. But if not, I wonder how it changes you to live with fewer and fewer markers.


Then again, suppose your accomplishments themselves are focused on the ephemeral...

Envy

If you hear that Jason has a degree in Chemistry, you figure he’s got some smarts and done some hard work. Likewise with a degree in Italian literature: Jason had to put in a lot of study to learn it. You might wonder how many jobs would be available for the latter degree, but college isn’t always a vocational school.

But a degree, or perhaps merely progress to a degree, in sociology doesn’t elicit the same respect. It gets more respect than gender studies, but that’s a pretty low bar.

Students in college tend not to have a list of accomplishments to their credit, aside from the stuff used to impress the admissions office. This is perfectly natural, but youth is often impatient.

Thinking over the list of targets of venom in the news lately: James Watson, Robert Heinlein, Charles Murray, Matt Taylor, even Bret Weinstein (and remember Larry Summers?): they all have this in common: they have accomplished things, earned respect—perhaps as a Nobel prize winner, perhaps as a ordinary professor. Their attackers generally are not in the same league. Those trying to intimidate Weinstein were students, not other professors. I didn’t hear of any Nobel prize winners in the line-up complaining about Watson at U of I. I've not heard that any of those claiming Heinlein was a terrible racist could write a tenth as well as he did.

Perhaps envy may play a big role in the noisy attacks. There's a lot of tribalism too, and of course the screamers get publicity, and often they get their way as well—something is structurally wrong there. When did it get to be carved in stone that youth are wiser and more noble than their elders?

But I get a strong smell of malicious envy from the social justice warriors.

Medicine Wheel

I was tasked with finding things to do/see in Big Horn in the summer(*), and one of the first places that popped up (as opposed to generic activities) was the Medicine Wheel. Archaeology has always been an interest of mine, so...

Stanford has a web page. There one learns that:

n 1974, an archaeoastronomer named Jack Eddy visited this Medicine Wheel and studied its alignments, that is, its arrangements of rocks, cairns, and spokes. He found the arrangements point to the rising and setting places of the Sun at summer solstice, as well as the rising places of Aldebaran in Taurus, Rigel in Orion, and Sirius in Canis Major -- all bright, important stars associated with the Solstice. Later another astronomer, Jack Robinson, found a cairn pair that marked the bright star Fomalhaut's rising point with the Sun 28 days before solstice.

and

The dawn or heliacal rising of a star is important because it pinpoints a date exactly. This is the day a star is first seen, just before dawn, after it has been behind the Sun for an entire season. From about 1200 AD to 1700 AD, these 4 stars would have acted as solstice markers for the Native Americans - Fomalhaut (F to D) would rise 28 days before the Summer Solstice, Aldebaran (F to A) would rise during the 2 days just before the solstice, Rigel (F to B) would rise 28 days after the solstice, and Sirius (F to C) 28 days after that, at the end of August and hence marking the end of summer and time to leave the mountain.

Which sounds quite complicated and interesting, but the diagram associated with it is not so promising

The cairns aren't exactly neat geometric points, and the resolution doesn't look much better than 5 degrees. And the cairn orientations don't seem to line up with their putative use as observation points. If Jack started with a list of stars significant to the Cheyenne and found things that lined up with each of them, I'd be OK with describing it as a rough-and-ready calendar--though not 100% convinced. If he got a list of stars that were "pointed at" and then went looking for which were significant, I'd be less convinced. "look elsewhere effect"

Whole hog

That phrase. "I do not think it means what you think it means."

Memorable but unremembered

On I65 one of the side roads leads to Walesboro. That name always reminds me of the line in "A man for all seasons": "Why Richard, it profits a man nothing to give his soul for the whole world... but for Wales?" Except, of course, that I generally only remember the last 3 words, and have to reconstruct the rest. It's a memorable line, but I can't remember it. I'm even worse at getting all the bits in order for the unforgettable passage that ends "Yes, I'd give the Devil benefit of law, for my own safety's sake!"

I've an excuse when an earworm of Hava Nagila turns into mud (or into Halva Nagila, or into Harvey and Sheila, or just repeats like a scratched record), since I never learned the actual words and my ear isn't tuned to pick out the phonemes of Hebrew.

But English is my native language. When my mind says "This is important; stuff it in one of the quick-access slots," how come half of it falls on the floor? I summon up a teaser or key line or executive summary, but most of the details are missing.

Credentialling

On I74 headed east to Indianapolis, there is a billboard touting the services of a law firm that promises to help you after an injury or similar loss. What caught my eye as I drove by was that they describe themselves as "an award-winning law firm."

Not "a case-winning law firm?" Or does that not matter until validated by some awards committee?

Two timing

Back in high school I read a book by Eddington in which he was explaining space-time. In one section, he suggested that different universes, with different numbers of space and time dimensions, would be limited in the ways they could intersect: that you could have a portal from a universe with 3 space and 1 time to one with 3 time and 1 space, but not to one with 2 time and 2 space dimensions. To this day I have no idea why he thought that.

However, it left this science fiction fan with a nagging idea for a setting: suppose we had 2 time dimensions? What sorts of things could happen?

Solving that puzzle had to wait until I got around to working out some of the dynamics, and when I finally did it turned out some other folks had already been playing with the idea. Including Sharshakavili (sp) and somebody named Bars.

To solve the dynamics you first have to decide whether you can violate causality on a macroscopic level--can somehow make your grandfather decide to become a monk before he met your grandmother? (Never mind quantum non-causality; I don't think I want to go there right now.)

I said no, and used a framework like the one Einstein used but with two time coordinates. Then you run into the question--how do you interact with a photon that's running along a slightly different timeline?

Hmm. I guessed that you would still be able to see it--but there'd be some probability that you'd miss seeing it entirely.

That was even cooler--you automatically would have trouble seeing some of the matter in the universe--it would be dark to you.

Presumably near things are mostly on the same timeline, and you'd only start to get major differences far away. OK, so what would a photon look like that came from a distant galaxy with a different timeline?

Oops. It would have the same number of "vibrations" in what would look like a shorter time--meaning it would be blue-shifted. Distant galaxies are red-shifted due to the expansion of the universe, and apparently the expansion is increasing (unless the supernova distribution is wrong somehow), which would make the redshift stronger, not bluer.

Plus, the blue shift complicates energy conservation. I think there might be a way to finesse that, but without either blue-shifted light or disappearing photons I think it safe to say we don't have macroscopic extra time dimensions. I gave up on the study. (If somebody wants to play around with a sci-fi setting in which multiple timelines interleave, feel free.)

On the other hand, if you've got 10 dimensions curled up in M-theory, Dr. Bars suggests that you can spare one for an extra time dimensions. He uses a formalism that uses position and momentum in symmetric ways, and argues from that symmetry that there should be another time dimension. (I think.) Unfortunately I don't share his optimizm about CERN discovering supersymmetry anytime soon--or anytime at all, for that matter.

Doing good

From Sidelights:
What embitters the world is not excess of criticism, but absence of self-criticism. It is comparatively of little consequence that you occasionally break out and abuse other people, so long as you do not absolve yourself. The former is a natural collapse of human weakness; the latter is a blasphemous assumption of divine power. And in the modern world, where everybody is quarrelling about the urgent necessity of peace, nobody notices how this notion has really poisoned the relations of nations and men.

Thus the Irishman would never have minded the English saying he was mad; or even that he was murderous and slanderous and cruel. There was something to be said for the assertion; and Irishmen were often ready, if not to admit it about themselves, at least to admit it about each other. The trouble began when the Englishman advanced the obviously ludicrous proposition that he himself was sane; that he was practical and sensible and well-balanced. No wonder a whole nation went wild at so fantastic a fancy as that.

What the Prussian said about the French or the other Latins was simply ignorance: the ignorance found only among the seriously educated. It was what the Prussian said about the Prussian, that made half the world smell afar off something that stank with spiritual pride.

The moral is the same about much milder and more amiable things; indeed it is rather specially true about mild and amiable things. The trouble with the philanthropist is not that he does not love all men moderately, but rather that he generally loves one man too well. And, contemplating the sort of philanthropist who is also an egoist, I am tempted to recommend him to try being a man-hater, that men may more easily love him. I am tempted to say to him: Hate men as a sort of holiday; beat and kick them for a reasonable interval; burn down their houses, in moderation, and lay waste all civilization within reasonable limits: But do not be kind merely to exhibit your own kindness; for that is an insult that is never forgiven.

When you are helping people, pray for a spirit of humility; I had almost said, when you are helping them, pray for an appearance of helplessness. The deadly word ‘patronage’ is, like so many such, a word that has decayed from a much nobler meaning. But in this sense we may find another significance in the old conception of patron saints. It may mean that a man has jolly well got to be a saint, before he ventures to be a patron.

Chesterton nodded a bit here: he did not predict the rise of pat-your-self-on-the-back-for-being-so-observant self-criticism.

Good ideas

One of the talks concentrated on how we should try to organize analyses, and not keep re-inventing the wheel. She showed lists of related analyses, and urged us to make sure that all code was in the repository and not private sandboxes. And that students should learn how to have their code reviewed.

All noble goals. (She has led a working group, is one of the young big names in the experiment, and is a pleasure to work with.)

However, several people who've trained more students than she pointed out a few problems. Part of the apprenticeship is to do some of the exercises yourself, and there's no better way to learn how to minimize a log likelihood function on a complicated data set than to do it yourself. And, then, when you want to try a full-blown analysis, you'll tend to use what you developed and understand the best.

Another problem is validation--are you sure you don't have some subtle bugs in your code or your procedures? They do a lot of cross-checking, but often there's no substitute for an independent analysis. Sam Ting tries to make sure that two independent analysis groups don't communicate with each other. He allegedly is the only one that sees both.

On the other hand, my analyses over the years would have been improved by some better coding practices and review. I kept a record of all my coding errors over a year, and found that the plurality were cut-and-paste errors. She's quite right about that.

And private code from somebody's sandbox is hard to maintain, or re-use when the student has graduated and somebody else wants to process a couple more years' data.

Reconnection

One of the talks was on the possibility of seeing solar flares with the IceCube neutrino detector. That might seem a little counter-intuitive: how do big magnetic disturbances manage to make neutrinos?

A plasma with a magnetic field in it will carry that magnetic field around with it as it moves. (The magnetic field acts on the plasma and the plasma acts on the magnetic field--plasma physics is hard.) So far so good--the plasma erupts from the Sun, and carries some of the Sun's magnetic field with it. Think of it stretching those field lines further out into space.

But it turns out there's a lot of turbulence there too, so the plasma sometimes gets whirled around on itself. What happens when the magnetic field lines cross?

You get what you might think of as a magnetic short circuit. The magnetic field "lines" join and shift--quite rapidly. And this happens over a fairly sizeable chunk of space.

A rapidly changing magnetic field produces an electric field (and vice versa, of course). So out in the middle of Nowhereville-By-The-Sun, a bit of the flying plasma experiences a strong electric field. The protons move one way, the electrons another. Most of them bounce off other things and slow down and go back to balancing each other's charge eventually, but some luck out and keep getting accelerated (remember that the reconnection region can be large). Acceleration over a long distance builds up speed.

Some of those protons (electrons tend to get scattered away more easily) head out in our direction, and eventually may hit the Earth's magnetic field and spiral in to be part of an aurora.

The protons of interest here head back to the Sun, where some of them smash into another nucleus. Those kinds of smashes usually produce pions, and the charged pions eventually decay into a muon and a few neutrinos. And we can maybe see some of those neutrinos. They aren't terribly high energy, but they're higher energy than those usually produced in the Sun--maybe 10 times higher.

It's ironic--neutrinos produced in the center of the Sun are ordinary low-ish energy, but those produced on the outside during flares can be quite a bit peppier. I can't think of any everyday examples, but I notice that boiling water in a pot only really splashes you when bubbles reach the surface and pop. The pop can really fling hot water around. Remember boiling something dry too fast back in chemistry class, and getting "bumping?"

We expect similar sorts of things to happen, but on even larger scales, when the blast wave from a supernova crashes into interstellar gas. Some of the neutrinos IceCube detected were over 10,000,000 times more energetic than ordinary solar neutrinos.

Limits

It isn't a great secret, though the latest negatives haven't been officially published. I suspect we won't have a smoking gun unless/until a Gamma Ray Burster or supernova lets loose in our galaxy. IceCube is designed to detect higher energy neutrinos than a supernova is likely to produce in its explosion, though the resulting shock wave hitting matter nearby is another matter.

Yes, I know it's odd, but the reactions that produce the supernova explosion are supposed to be the ordinary nuclear ones. When the shock wave from the blast (with magnetic field embedded) later interacts with gas (expelled from the star years before), the resulting interactions can accelerate particles to extremely high energies.

What that means, if I understand the matter correctly, is that the most likely neutrinos are too weak to ring up unless there are boat-loads of them, and we'll only get boat-loads if the source is close. And we might have to wait a while for the really high energy stuff to show up, since it isn't produced right away. And even longer for the protons and other nuclei to arrive. (If a source 50,000 light-years away produces iron nuclei whose trajectory is bent a mere three degrees, they'll arrive over three months after the light and neutrinos do. And we don't know in any detail what the magnetic field are out there, so we can't predict when.)

So we see GRBs in other detectors (SWIFT), but don't see anything out of the ordinary in IceCube. So far. Maybe there's an unnoticed glitch in the analyses: I'm not in a position to tell. I just sit through the talks, which show large p-values after unblinding.

There are plenty of things we can do, but some of the tantalizing problems are staying that way.

Elders

You presumably pick elders as leaders because experience has given those of them willing to learn some perspective, an understanding of what patience means, some sense of proportion, and accumulated knowledge. Not that we have a habit of doing that in this country, but think about organizations of smaller scale than the state, and you may see instances of what I mean.

You'd also hope that habits of virtue would provide some inertia against the pulls of temptations.

Maybe they do--somewhat. But I suppose that power has its own set of temptations that most of us haven't been exposed to: to listen to sycophants, to be flattered by groupies, to come to enjoy arbitrary exercise of power. But history and literature (and, sometimes, our acquaintances) are full of the theme of a worker/conqueror who builds a fortune/dominates an empire only to have the children/grandchildren (born to power) fritter it all away. (Yes, I know I'm defining virtue a bit widely when talking about warlords, but they have to have at least some self-discipline and courage.)

I'm not sure there's a simple and robust way to survey this. If, for example, you looked at the history of family businesses, you might have some difficulty, from outside the family, in distinguishing mere lack of skill from carelessness.
