Juno at Jupiter

NASA's Juno spacecraft is peacefully orbiting Jupiter these days, on an elliptical orbit that brings it close to the planet every 53 days. It is doing lots of science about magnetic fields, the planet's gravity, and so on, very technical stuff. But it also has an infrared camera, which produced the image above, and a marvelous visual light camera. That camera took the images that were assembled into the portrait of the planet's South Pole shown below. While the equatorial regions are organized into those famous bands, which haven't changed much in 300 years, the poles seem to be a chaotic mess.

Bamburgh Castle

Bamburgh Castle looms over the northeast coast of England, remnant of ancient kingdoms and folly of Victorian magnates. It has much in common with the Tower of London: both are places of great antiquity and extraordinary history, but both are still occupied and have been rebuilt and restored so many times that you can never tell who might have placed the particular stones in front of you, or in which century.

Bamburgh was the citadel of one of the earliest Anglo-Saxon kingdoms, Bernicia, which is first attested under a King Ida in 547 CE. Ida was known as Flame-Bearer, probably in reference to his favorite style of warfare. He is supposed to have named the fortress Bebbaburgh after one of his wives.

A 9th century Welsh text calls the place Din Guarie, which would be a good name for Brittonic fort. On the basis of this one source, some authorities assert that Bamburgh was the seat of a Brittonic lordship in the fifth century, perhaps even the capital of Coel Hen's semi-historical kingdom of the north. Coel Hen is Old King Cole, which should give you an idea how much myth is mixed in all of this. Archaeology does show that this strategic hilltop has been occupied since Mesolithic times, and there have been numerous Bronze Age and Roman finds finds. So perhaps when the Roman world fell apart some chieftain did take over this spot and build a hall for his gold-torc'd men.

According to Bede, between 547 and 590 the place passed back and forth between Britons and Anglo-Saxons three times. After 590 it became the seat of the Kings of Northumbria, including the mighty Bretwaldas (high kings) Edwin, Oswald and Oswy. The Staffordshire Hoard is thought by some historians to be the loot collected after one of the battles between Edwin or Oswald and the rival kingdom of Mercia.

The Northumbrian fort was wrecked by the Vikings in 993. After the Normans came they built a castle on the spot, and in 1095 King William II besieged it during the revolt of Robert de Mowbray, Earl of Northumbria. After that it was a royal castle for 600 years. The keep was built by Henry II, who reigned from 1152-1189.

The castle was maintained as a royal base in the north through the high Middle Ages and figured in many campaigns, although the Scots never tried to besiege it. The walls seem to date to the 14th century, although I can't find any definitive statement on the matter. In the Wars of the Roses the castle passed back and forth between factions, and then in 1464 it was besieged by Richard Neville, the Earl of Warwick, who comes down to us under the title of Kingmaker. He took it after using artillery to batter a breach in the wall, making it the first English castle taken in that wise.

After the union of the crowns of Scotland and England in 1603 the castle was of no more military use, so James VI/I gave it to the long-time wardens of the castle, the Forster family. They could not afford the upkeep, so it deteriorated badly in the 17th century; in 1700 they went bankrupt.

The castle then passed to Nathaniel Lord Crewe, Archbishop of York, on whose death it formed part of a charitable trust. The trust's activities included a school for girls and hostel for shipwrecked mariners, both of which were housed in the castle. (One hopes they were not adjacent.) The trust was administered in the later 18th century by Dr. John Sharp. It was Dr. Sharp who began restoring the castle, an effort that sputtered along for a century. It was finally bought by the Victorian era industrialist William Armstrong (1810-1900), who spent some of his gigantic fortune on a major restoration but died before it was completed. That's his coat of arms above, as it appears above the entrance to his quarters in the castle.

Thanks to Armstrong parts of the castle became a lavish modern mansion; these are called the "state rooms." The castle still belongs to the Armstrong family but is open to the public.

Serious archaeology at Bamburgh began in 1961. The director was Brian Hope-Taylor, a noted archaeologist and an even more noted eccentric. He excavated at the castle on and off until 1974, but then illness cut short his work and he died before he ever published his finds. One of his team's discoveries was the small gold ornament dubbed the Bamburgh Beast (above.)

When excavations resumed in 1996 the new team, led by Graeme Young, thought that all of Hope-Taylor's notes and papers had been lost, so their only clues to what had been done came from interviewing some elderly former volunteers. But then one day they were exploring the castle grounds with one of the keepers, looking for a place to store their tools. They broke open a small storeroom built into the castle walls and found Hope-Taylor's study, untouched since the excavations ceased; there was even a 1974 copy of the Daily Telegraph on the desk. All of his notes, maps, and plans were there, right where he had left them.

The new excavations have uncovered many remains of the royal Northumbrian fortress, including fragments of a stone throne (which might have looked like the reconstruction above) and traces of a great mead hall.

The biggest part of the archaeology done at Bamburgh was the excavation of more than 100 burials from the Bowl Hole Burying Ground, which is along the coast a ways south of the castle. The place had long been known because skeletons occasionally eroded out of the bluffs after storms. The burying ground proved to date to the 7th through 9th centuries. The burials showed a confusing mix of pagan and Christian characteristics, for example some of the most pagan looking burials had crosses around their necks. The skeletons were mostly tall, robust people, and some had sword wounds, so it is thought to be an elite group. Elemental analysis suggested that only a minority were local, others came from other parts of Britain, and a few were born in Norway or Denmark.

I would love to tell you more about the project, but as with most British digs the results have only been published in obscure journals and presented at out-of-the-way conferences. There is an excavation blog, but it has been scrubbed of all information that anyone might want to publish, making it one of the most frustrating things I have ever read. One day I suppose there will be a fat report that I will have to go England to read – provided, of course, that Graeme Young doesn't also die before he gets around to it. But meanwhile it seem like a wonderful place to visit.

And Now a Confederate Monument in St. Louis

Good article on the brewing fight over the Confederate monument in St. Louis' Park:
Tishaura O. Jones, the city treasurer, started a GoFundMe page to raise money for the monument’s removal. In about a week, she has gathered more than $11,000. She passes the memorial during her weekly drive to the grocery store, usually with her 9-year-old son in tow. “What I’m trying to do is set the record straight,” she said. “The Confederates, in my opinion, were traitors. And in this country, we honor patriots.”

Other St. Louisans are resisting the move, arguing that removing it would be tantamount to blotting out the history of the Civil War. Some have said that the enormous monument is too heavy and expensive to move, particularly when it doesn’t have an obvious new home. Still others say that the monument has rarely attracted attention for more than a century — why should St. Louis be caught up in a debate that, in their view, belongs to the Deep South?

“My first choice would be that everyone forget it was there, like before,” said George Stair, 77, who paused at the monument on an evening walk with his wife, Jane Yu, who agreed that it should stay.

Mr. Stair gazed at the sculpture. “I feel like it’s O.K. to honor ordinary soldiers,” he said. “People went to Vietnam even though they didn’t agree with it.”
In Missouri there is the additional point that although the state government remained in the Union, many citizens were Confederate sympathizers. About 110,000 Missourians served in the Federal army, and at least 30,000 on the Confederate side. Plus there were all those bushwhackers (Quantrill, Jesse James, etc.). So removing all Confederate monuments from the state could be seen as an attempt to wipe out that part of its history.

Incidentally I thought Pat Buchanan asked an interesting question the other day: when will statues of Sherman and Sheridan have to come down because of the horrible way they treated the Indians?

Tyler Cowen on Agnosticism

Tyler Cowen was recently asked why he doesn't believe in god and wrote an interesting response:
1. We can distinguish between “strange and remain truly strange” possibilities for origins, and “strange and then somewhat anthropomorphized” origin stories. Most religions fall into the latter category, all the more so for Western religions. I see plenty of evidence that human beings anthropomorphize to an excessive degree, and also place too much weight on social information, so I stick with the “strange and remain truly strange” options.

I see the entire matter of origins as so strange that the “transcendental argument” carries little weight with me — “if there is no God, then everything is permitted!” We don’t have enough understanding of God, or the absence of God, to deal with such claims. In any case, the existence of God is no guarantee that such problems are overcome, or if it were such a guarantee, you wouldn’t be able to know that

2. The true nature of reality is so strange, I’m not sure “God” or “theism” is well-defined, at least as can be discussed by human beings. That fact should not lead you to militant atheism (I also can’t define subatomic particles), but still it pushes me toward an “I don’t believe” attitude more than belief. I find it hard to say I believe in something that I feel in principle I cannot define, nor can anyone else.

2b. In general, I am opposed to the term “atheist.” It suggests a direct rejection of some specific beliefs, whereas I simply would say I do not hold those beliefs. I call myself a “non-believer,” to reference a kind of hovering, and uncertainty about what actually is being debated. Increasingly I see atheism as another form of religion.

4. I am struck by the frequency with which people believe in the dominant religions of their society or the religion of their family upbringing, perhaps with some modification. . . . This narrows my confidence in the judgment of those who believe, since I see them as social conformists to a considerable extent.

That all said I do accept that religion has net practical benefits for both individuals and societies, albeit with some variance. That is partly where the pressures for social conformity come from. I am a strong Straussian when it comes to religion, and overall wish to stick up for the presence of religion in social debate, thus some of my affinities with say Ross Douthat and David Brooks on many issues.

6. I do take the William James arguments about personal experience of God seriously, and I recommend his The Varieties of Religious Experience to everybody — it’s one of the best books period. But these personal accounts contradict each other in many cases, we know at least some of them are wrong or delusional, and overall I think the capacity of human beings to believe things — some would call it self-deception but that term assumes a neutral, objective base more than is warranted here — is quite strong. Presumably a Christian believes that pagan accounts of the gods are incorrect, and vice versa; I say they are probably both right in their criticisms of the other..

Add all that up and I just don’t believe. Furthermore, I find it easy not to believe. It doesn’t stress me, and I don’t feel a resulting gap or absence in my life. 
Like Cowen, the root of my unbelief is that positing "God" does not make the world more understandable to me. It simply moves the discussion to even more abstruse mysteries. I regard the origin and nature of the universe, and of human life, as profoundly mysterious, which is why I also avoid the term atheist, but I just don't see how the concept of God helps us understand anything. Plus much about all religions feels to me too much like what we might wish to be true, and I always rebel against any theory that seems emotionally pat.

Also like Cowen I think that religion fulfills very important social and psychological roles and I wonder what will happen to human societies as it fades. (Conversion to Mormonism has been found to be the most effective anti-poverty program ever tried.) I also sometimes miss the richness added to the world by beliefs in the spirits of springs and groves, the ghosts that haunt old houses, fairies who cross between this world and some other. But maybe most future people will feel as he and I do, and as my children seem to, comfortable with our lack of belief.

Body Language for Project Managers

One of the more amusing parts of the project management course I just completed was this discussion of body language:
The ability to read body language is invaluable in situations where enhanced communication is critical. Basically, every gesture can send a message. Here are a few of the most important signals being transmitted by body language:

Head tilted forward or sideways is receptive, while a face turned away acts to distance.

A head tilted backward so a person can look down their nose at you is just what it seems.

Eyes that blink rapidly or constrict are signaling distress or disagreement.

A stare of longer than two seconds can be seen as a challenge.

Removing glasses while making a point intensifies eye contact, humanizes the face, and removes a barrier between the parties.

Mouth movement, such as licking or biting the lips is a sign of discomfort.

Thinning lips is a negative response. Yawns can mean some level of discomfort or boredom.

Shoulders that roll or shrug are a strong sign of receptiveness or submission.

Squaring of the shoulders indicates an authoritarian attitude.

Arms on the chair with palms up indicate goodwill and honesty.

Self-clasping, such as holding an arm or hands, indicates the need for reassurance.

A body that leans forward or toward someone shows attention.

Angling the body is a cutting off gesture.

A tie that is loosened slightly portrays openness.
There is also a section on how to improve your own body language, from which I draw the following mysterious item:
Try sitting as if someone were pulling your hair to the ceiling.

Wonders of the Seven Seas

Marvels of Things Created and Miraculous Aspects of Things Existing, 13th century.

The Project Management Course

At the behest of my esteemed employers, I just completed a 22-hour course in project management for engineers. Some of it was not relevant to what I do, but much of it would be very useful for anyone just starting out in project management. For example, there is an excellent description of what has to be accomplished in a kickoff meeting, and a good discussion of how to delegate. Since I have been doing this full-time for about three years and worked closely with my old boss for nearly a decade before that, I already knew a lot of this. But it was interesting enough that I don't regret having done it.

At the beginning there is a description of a "successful project manager" that is based, they say, on interviews they have conducted over the years; the authors are business consultants who work in the engineering industry. It's just what you would expect from any list of successful Americans: project managers keep physically fit, dress well, tell the truth, treat everyone with respect, don't waste time with trivial matters, and get to the office an hour early to have time for long-term tasks that may get crowded out by crises once the rest of the staff shows up, etc. They "eat, sleep and breathe the project."

There is also an amusing lesson that contrasts the ideal type, the Strong Project Manager, with the mere Project Administrator:


As I worked my way through all these lessons illustrated with photographs of models in spotless, utterly dirt-free, obviously-never-been-on-a-construction-site hard hats trying to look like people building skyscrapers, I amused myself by collecting kernels of Project Management Wisdom. I find that these add up to a sort of pointillist picture of American business life and its values. So here, presented in no particular order, are some of the pearls you need to absorb to become a Strong Project Manager; all of these are direct quotations from the lessons.

Start now.

Keep control of your own time or others will.

When someone asks for your time, make ‘No’ your first thought.

Balance is the key.

The best way to solve problems is to avoid them.

Don’t be afraid to decline attending meetings that are likely to waste your time.

Never say “No”; say “Yes, if...”.

Keep your files in order.

Be assertive.

Recognize when you have to compromise.

Deliver faster than you promised.
Deliver more than you promised.

Eliminate excess perfection.

Keep the lines of communication open.

It’s impossible to see any further ahead than you look.

Give credit. Take blame.

Do not draw a line unless you know what it means.

Schedule meetings at odd times (e.g., 10:53 a.m.); this encourages punctuality. Start meetings at the scheduled time, even if all participants are not there.

Make sure only your agenda takes place.

Brief emails are always better.

There is nothing that destroys the quality of a project more than trying to meet an unrealistic schedule.

Pick one solution and go with it.

A professional (not emotional) response is the best way.

It is a well-established fact that people perform better and make fewer errors if they are able to work in a comfortable atmosphere with other team members. Even though a small amount of stress is good stimulation for most people, constant levels of highly charged stress usually cause the performance to decrease and more errors to occur.

Do not waste time in pleasantries.

Document everything.

Do not surprise your boss.

An Ounce of Prevention is Worth an Ounce of Cure

People have long believed – and by long I mean 4,000 years – that the right sort of lifestyle, accompanied by the right sort of medical care, will stave off illness. Thus we are constantly urged to get regular checkups, mammograms, colonoscopies, etc. But the evidence that these things actually extend life is weak, and since they cost money many medical economists think they are a waste. The latest study finds that people often respond to slightly alarming signals picked up during checkups by getting a lot of health care that doesn't help them:
Using unique individual-level panel data, we investigate whether preventive medical care triggered by health checkups is worth the cost. We exploit the fact that biomarkers just below and above a threshold may be viewed as random. We find that people respond to health signals and increase physician visits. However, we find no evidence that additional care is cost effective. For the “borderline type” (“pre-diabetes”) threshold for diabetes, medical care utilization increases but neither physical measures nor predicted risks of mortality or serious complications improve. For efficient use of medical resources, cost effectiveness of preventive care must be carefully examined.
So far as we can tell, there isn't much reason for healthy people to see a doctor.

On the other hand there is strong evidence that women who get pre-natal care have healthier babies, even when the checkups lead to no interventions at all. So this is a complicated business, and there may well be interventions that help. The ordinary sort of medical check-up just doesn't seem to be one of them.

This has some political importance when it comes to health care policy. Liberals have long hoped that universal health insurance would save a lot of money, because people would get to the doctor when their problems were small and easily treatable, rather than waiting until they are really sick and going to an emergency room. But the evidence that this saves any money at all is weak, and the cold truth seems to be that the more health insurance you give people the more they spend on health care.

A Time of Testing

We seek to be faithful in a time not of our choosing but of our testing. We resist the hubris of presuming that it is the definitive time and place of historical promise or tragedy, but it is our time and place. It is a time of many times: a time for dancing, even if to the songs of Zion in a foreign land; a time for walking together, unintimidated when we seem to be a small and beleaguered band; a time for rejoicing in momentary triumphs, and for defiance in momentary defeats; a time for persistence in reasoned argument, never tiring in proposing to the world a more excellent way.

–Richard Neuhaus

Khangchendzonga National Park

Today's place to daydream about is Kanchendzonga National Park in Sikkim, India, bordering Nepal in the Himalayan highlands.

The topography is extreme, rising from 6,000 feet to 28,050 feet (1,830 to 8,5550 m). In area it measures 328 square miles (850 km2).

The area is most famous for its extremely tall mountains, including the third highest in the world.


But I am more entranced by the high wooded valleys, a wonder of biodiversity that led to the park being named a UNESCO World Heritage Site.


Cloud forests.



Some of the amazing wildflowers.



Birds, including (top) the Satyr Tragopan.

Mammals include snow leopards and red pandas.

There are 18 glaciers and 73 glacial lakes, inhabited by a wide variety of folkloric creatures, from goddesses to goblins.


There is an old and famous monastery, Tholung, and many other sacred sites.

What an extraordinary place.

What the Man Wants

Interesting bit from Tom Friedman's account of a tour of America's "heartland." He is interviewing Ron Woody, county executive for Roane County, Tennessee, home to half of the Oak Ridge laboratory:
It turns out that it’s not that hard to train someone, even with just a high school or community college degree, to operate an advanced machine tool or basic computer. “Factory managers would say, ‘I will train them and put them to work tomorrow in good jobs” requiring hard skills, said Woody. “The problem they have is finding people with the right soft skills.”

What are those soft skills? I asked. “Employers want someone who will get up, dress up, show up, shut up and never give up,” Woody responded without hesitation. And there are fewer workers with those soft skills than you might think, he added.
In a deep, long-term, philosophical sense, is it good or bad for a country that such people are in short supply? Do the virtues that make a good factory worker make a good citizen? Or do people need to compartmentalize, acting one way at work, another way at home, and some third way politically?

Meanwhile I will say this about Trump's victory: it has gotten a lot of elite globe-trotting types like Tom Friedman to take a serious interesting in places like Austin, Indiana, Louisville, Kentucky, and Roane County, Tennessee. In that sense Trump's voters may have been onto something.

So Much for Infrastructure

Trump ran on a promise to invest a trillion dollars in American infrastructure. And if you look at the new budget's 10-year projections, you see a line item of $200 billion for the "Infrastructure Initiative." Not a trillion, but at least a substantial sum, right? Sadly no. Scanning the rest of the budget, you see the following cuts over ten years:


That adds up to more than $300 billion in cuts. If something resembling this budget is actually enacted, Trump will no doubt trumpet the Infrastructure Initiative as a big deal – no, a HUGE deal – and give speeches at some of the big project groundbreakings. But all the money and then some comes from cuts to infrastructure programs in other parts of the budget.

Honestly I don't think anything like this budget will emerge from Congress, because it makes big cuts in programs like the FBI and the State Department that have powerful Republican friends. But Trump's team is just caught in the scissors of budget math and Republican promises. If you want to 1) cut taxes, 2) preserve Defense spending, Social Security retirement programs, and Medicare, and 3) pretend to care about the deficit, you essentially have to eliminate the rest of the government.

Toshi Yoshida

Toshi Yoshida (1911-1995) was a Japanese painter and maker of woodblock prints. He learned print-making from his father, Hiroshi Yoshida, doing what was by the early twentieth century the most normal and traditional sort of Japanese prints. This was an old-fashioned Japanese family business in which the son was still a junior apprentice at 25, filling in details on compositions chosen by his father. The oldest works I can find in his name are from 1938, like this one: Tokyo at Night, Shinjuku.

Hie Shrine, Tokyo. Note the signature in Latin letters, which means this print was sold to a foreign buyer after World War II.

Yoshida managed to become independent during World War II, when he traveled as a journalist. But as you would expect the woodcuts from the war years are also strongly traditional. Idabashi, 1939.

Sacred Grove, 1941.

Shirasagi Castle, 1942.

In the poverty-stricken years after the war Yoshida seems to have kept on with the traditional Japanese material, I assume for sale to Americans and other foreigners; or perhaps his works were sold as cheap prints to decorate newly rebuilt homes. White Plum in a Farmyard, 1951.

According to online biographies, Toshi always wanted to experiment with abstract art, but never dared until after his father died. Once out from under the paternal shadow he began to experiment in many directions. The Beginning of Day, 1957. He actually produced quite a few abstract works, many of which were collected in the US and Europe.

Lost World, 1964. I sense in Yoshida a lifelong ambivalence about the traditional Japanese art in which his father trained him. He never abandoned it, but he kept trying to branch out.

Yoshida had always liked drawing and painting animals, and beginning in the 1950s he began to produce animal prints and picture books for children.

But he never stopped working with traditional Japanese subjects. Irozari Evening, 1961.

Morinji in Spring.

Autumn in Hakone.

Stone Garden, 1963.

Yoshida traveled to America and made prints of American scenes. Monument Valley, 1970.

In 1980 Yoshida opened a print-making school in Nagano Prefecture. He trained many future professionals there, including numerous Americans. Dance of Eternal Love, 1970.

Tokyo Bird Park, 1980s.
