Repost: Between Good Friday and Easter comes the Sabbath

I don't usually re-post things, but this one struck me again.

On Good Friday we have the sacrifice and the dereliction. On Easter Sunday we have the resurrection and the joy. What's the Saturday in between for?

Imagine if you were there.

It was the Sabbath, when no one was supposed to work (except God, busy maintaining the world). OK, maybe you had to rescue the farm animals stuck in the ditch, or care for the sick, but otherwise everything went on hold. You had to wait to finish the schoolwork, wait to conclude the deal, wait to finish painting, wait to finish the preparations of the body for burial. The disciples had to wait before trying to skedaddle out of town (they could only go a Sabbath-day's journey), though the Sabbath gave them a slight break before the authorities would start hunting for them.

On that Saturday/Sabbath, there was nothing they could do. They probably didn't know what to do anyway, except lie low and wait.

One of the lessons of the Sabbath was "you don't hold up the world." For six days you work and for one day you rest and realize that the results depend on God.

Lots of life is bound up with waiting. A boy wants to be a fireman, but he'll have to wait. A couple want a baby--they'll have to wait. Why can't you learn to walk right away? Travel takes time. Growing takes time. Ripening takes time. Wisdom takes time. Even drying clothes takes time.

And God makes us wait in other ways. We read of many prophets, but there seem to have been spans of time with no prophet--especially the four hundred years before Jesus. "You have enough for now, follow what you know and wait." How long have we been waiting for Jesus' return? And, I suppose, how long has God been waiting for us to finish reaching the world?

Plant the crops and wait for rain. Mend the fishing nets and wait for the rain to stop.

Newlyweds find a monthly interruption to nuptial delights--and it lasts a week, too. Why? I don't know: Waiting again.

Someone said that 90% of life was showing up. That's kind of a primitive way of looking at it, but a lot of life is spent being there and being ready and waiting. And I guess God wants it that way. How to faithfully occupy our time while waiting is a matter for another meditation.

But for this Saturday/Sabbath, we wait, as they waited; for Easter isn't about what we can do.

Platonic?

I'm a little puzzled. There are ancient Platonist threads in Christianity, in which the physical, though created good, must be left behind as the soul reaches for God. The idea comes across to me as almost gnostic.

We were created, and therefore have a nature and form. Perhaps that form, like a caterpillar's can change to something else, but that in turn will also be a form.

To be united with God, therefore, happens through a particular form.

That does not have to limit the depth of the union: consider Jesus as the ultimate example. He had the form and nature of a man, but was also fully God.

So there's no intrinsic reason why divinization demands that we abandon our physical bodies. Some austerities may be required along the way (and in this fallen world almost always are), but they are only a secondary means. That we cannot know God as He knows Himself ought to be obvious, though we doubtlessly need regular reminders.

That all seems pretty straightforward. But quite a few Christians through the centuries hold pretty much the opposite.

What am I missing?

UPDATE: If the process of union were our operation instead of God's I could see a reason for the focus. But since divinization is God's doing, we should expect the miraculous and look to the examples we know: Jesus.

Microcracks to prevent cracking?

With a hat tip to the CERN Courier, look at a story about making glass less brittle by micro-grooving the glass and filling in the grooves.
Here we report the implementation of these features into glass, using a laser engraving technique. Three-dimensional arrays of laser-generated microcracks can deflect and guide larger incoming cracks, following the concept of ‘stamp holes’. Jigsaw-like interfaces, infiltrated with polyurethane, furthermore channel cracks into interlocking configurations and pullout mechanisms, significantly enhancing energy dissipation and toughness. Compared with standard glass, which has no microstructure and is brittle, our bio-inspired glass displays built-in mechanisms that make it more deformable and 200 times tougher. This bio-inspired approach, based on carefully architectured interfaces, provides a new pathway to toughening glasses, ceramics or other hard and brittle materials.

Unfortunately the site wants fees (unless your university has already paid up), but the pictures and the abstract should give the gist of it. It can surely be scaled up to small objects, though I don't know about windshields. Cool.

Uniforms

When I first put this uniform on,
I said, as I looked in the glass,
"It's one to a million
That any civilian
My figure and form will surpass.
Gold lace has a charm for the fair,
And I've plenty of that, and to spare,
While a lover's professions,
When uttered in Hessians,
Are eloquent everywhere!"
A fact that I counted upon,
When I first put this uniform on!

I said, when I first put it on,
"It is plain to the veriest dunce
That every beauty
Will feel it her duty
To yield to its glamour at once.
They will see that I'm freely gold-laced
In a uniform handsome and chaste" -
But the peripatetics
Of long-haired aesthetics,
Are very much more to their taste -
Which I never counted upon
When I first put this uniform on!
William Schwenck Gilbert

I don't clearly understand what my better half sees in me; though I'm profoundly grateful that she does find something attractive. So perhaps it doesn't make a lot of sense for me to spend any effort trying to figure out why women seem attracted to men in uniform. But

Gilbert emphasises the flashy aspect of the uniform, and I've heard others say it is the "safe bad boy"--somebody dangerous but disciplined; strong for you and strong for your children and likelier to have strong children with. The latter seems a trifle reductionist, but it probably plays a role.

BTW, I'm talking about the ideal of the soldier, not the real one the woman gets to know later. We can all find plenty of exceptions--or at least those of us who actually know policemen or soldiers can.

Another aspect occured to me yesterday. A soldier or policeman takes on an open-ended commitment. So does a parent or a spouse. (So also, whether they want to know it or not, does someone who becomes a Christian.) The ideal soldier is someone who is capable of commitment--a creature a little scarcer on the ground that he used to be. I'd think that would appeal to both sexes, but the effect in men is probably swamped by other preferences. Someone who has the sense of adventure and trustworthiness for the long haul is a good catch.

When the big one goes off

--which it will, eventually, somewhere--what should you do?

Back when I was in 6'th grade the school library had The Effects of Nuclear Weapons on the shelf and a couple of us read it. I know that doesn't match the current reading level rules, but we were too ignorant to know that the best authorities are sure we couldn't possibly have understand it, so we studied it anyway. If it had been part of the curriculum that might have been another story... It was fascinating reading. Nobody we knew had fallout shelters--nobody was going to bother nuking Liberia, and it wasn't in fashion back in the States.

People are still thinking about these things--more so as more and more countries decline to trust their erstwhile allies. (There's been a rumor for decades that Japan has all-but-final-assembly parts in hand, and if I were running Japan I'd have looked at Obama and completed the assembly.) Some are going to come loose, and some will be deniably shared with loyal partners.

So, what should you do?

Homeland Security thought about the most likely target (DC) and most likely weapon (small), and came up with some common sense suggestions. (Livermore helped) Don't run; hide for a day until the fallout dies away. The blast damage from a small bomb isn't gigantic. If you survive that OK, and your house doesn't catch fire, the biggest threat is the fallout--most of which decays to harmlessness in a few days. One day is what they suggest. One hour minimum sheltering where you are, and then getting into a place with thicker walls if it is really close by.

A car breathes (or else you'd suffocate on a long trip), so it will suck radioactive dust into the cab as you drive to escape. Plus, the car walls are kind of thin, and don't offer as much shielding as you'd like. And sitting in the worst traffic jam in DC history while radioactive rain goes pitter-pat on the windshield is probably not good for your blood pressure.

I'm not used to reading radiation safety discussions with doses this high--if your dosimeter shows 10mrad exposure people start asking questions about where you were and what you were doing. 10rad...

FWIW, chemical weapon defense is not too dissimilar. Hunker down someplace sheltered while things dissipate and don't run.

San Francisco protests

You've read of the protests against Google buses and of the tipping of smart cars. Assume the second is related to the first, though maybe vandals just noticed how easy it was to do and the idea caught on.

At first blush it looks like an ugly case of envy and an unwarranted sense of entitlement.

At second blush, it still does.

But set aside the nonsense. I think they have reason to be angry. What is there for people who aren't that bright to do? We honor work that makes someone rich, work that makes someone famous, work that makes someone powerful. But when was the last time you heard of a business section feature highlighting a freelance handyman? We boast of automating away any work that isn't intellectual (and even some of that). Sci-fi has dreamed for years of humanity evolving into pure minds--those who aren't so bright weren't on the horizon at all. Brave New World is one obvious exception.

So if many of the simple jobs are automated, and cheap foreign labor is imported to do most of the rest, what kind of work is left? We're made to work and serve, and bread and lolcat circuses don't satisfy. Google isn't a villain for treating its employees well, nor is it to blame for what we as a culture have decided to do. The prejudice against manual labor is decades older than google. We've systematically reduced opportunities for whole classes of people. I don't think it was deliberate, mostly.

If that's the real problem, what's the real solution--or better, an improvement, there being no perfect solutions?

I know, I know--it takes a little chutzpah to think I might know their problems better than they do, and disregard what they actually say. I don't like it much when people explain to me how my consciousness hasn't been adequately raised to make me fully understand and bewail my "white privilege." Sauce for the goose is sauce for the gander--see how they like it.

Through the Looking Glass

I interpret the stories about Al Sharpton a little differently from the way his fan base does. If it is true that he worked as an FBI informant against the mob, I say that even a race-baiting demagogic extortionist can show courage and a love of justice. His fans say that the great leader would never stoop to such a discreditable practice as fighting crime alongside the FBI.

We may live in the same planet, but I'm not sure we live in the same universe.

Bits from non mainstream news

In an article explaining how the Liberian embassy's bank is closing their account, this bit:
The closure of the account has arisen fears among diplomats at Liberia's mission in the U.S. with some wondering how the decision would affect their salaries, rent for the office, phone, gas and heat bills and other related expenses. Employees are paid every three month period: January-February-March payment have reportedly been made already with the next scheduled payment set for April-May-June, a source told FPA.

That kind of payment schedule seems calculated to maximize uncertainty and hedging via under-the-table deals.


Ebola made an appearance in Liberia. This outbreak came from Guinea, not from a local reservoir, but some government officials are trying to be extra safe--and running into push-back.

Monkey, one of the animals listed as a carrier of Ebola is a favorite bush meat for many Liberians, an aged old food and convincing people to stay away from a food they have been consuming for years is proving difficult.

As quoted later (dry meat is, if I recall correctly, smoked bush meat; in this case monkey):

"They said the sickness came from Guinea and people in Guinea do not eat dry meat so they just trying to spoil our business," said Ma Tenneh.

"During the war, they were eating human beings, that one na make them sick, that now they say that meat making people sick. They are spoiling our business and it is our living. The people who are eating dog meat, what they will say about them? They are just complaining about dry meat, people eating itchy dog, it is not killing them.They know how far the sickness coming from before they lying on meat."

The language may be unfamiliar, but the sentiment is very familiar: the bureaucrats in charge don't have a clue. ("lying on" = telling lies about)

In Guinea where the outbreak began this would be a reasonable precaution, but the Liberian cases were different:

Noting that the result has shown that the virus exist in the country, Dr. Gwenegale further said the two results indicated a lady has died from the virus in Foya Lofa County while her sister taking care of her was infected.

He explained that the infected sister who contracted the virus had ridden a taxi late Sunday evening, and slept in the home of the taxi driver who is thought to be suspected of catching the virus.

That suggests a possibly more effective angle for control. FWIW, private cars are not common and taxis are not terribly expensive, so this infected driver doesn't just expose the rich.

Is it my imagination

Or does the Fleur-de-lis look like the end of a pike? Maybe I've an overactive imagination, or maybe the symbols were overloaded. Why couldn't it be a flower and a threat at the same time?

Crud. Too late

I postponed making a phaser pointer too long. This one is ridiculously small, though. (The price of models was off-putting: that's my excuse and I'm sticking to it.)

A few exercises...

Tall and tan and young and lovely,
The girl who looks so Swedish goes jogging,
And as she passes each one she passes goes "Ow"
Oh, but her knees knock so badly.
How can I tell her of biomechanics?
Yes, I would give advice glady.
But I thought it would be impertinent. And when she finally stopped to walk, and her walking stride also had the same feature, I was glad I hadn't made any suggestions...

Grail hunters

The two researchers, Margarita Torres and Jose Manuel Ortega del Rio, authors of the book, "Kings of the Grail," believe they found conclusive evidence from ancient Egyptian scrolls documenting that Muslims stole the infamous cup from Jerusalem and took it to Egypt. They say it was then disguised with jewels and eventually given to Spanish King Ferdinand I as a gift.

How do I doubt thee? Let me count the ways...

The story came out yesterday, so I'll give it the benefit of the doubt.

Reporters are apt to get details wrong, and also (for example) not notice that the researchers are promoting a book. They are often very trusting souls. But I'm kind of surprised the editor didn't notice that ancient Egyptian scrolls are unlikely to describe Muslim activities. I think the (much later) Muslims of the area would have been more likely to write on codices, but maybe I'm wrong. Still, disguising the cup with jewels, and then giving it to the infidels they'd be hiding it from? And most unlikely of all: a gold cup? In the hand of a carpenter in a group of fishermen (and a retired tax collector), after Judas griped about wasting money on frivolity?

And for those for whom it is significant, can even the original be more important than the cup we receive?

The flip side of exotic

I wrote of the enjoyment of the exotic, and how stretching the imagination can enrich the knowledge of what we have.

But, as with the story of the animals choosing a king, knowledge is not the only possible measure of goodness. Novelty is a great thing, but not the only thing. My Better Half always knows what I'll answer to her question “What do you want for your birthday dinner?”

One of my flaws is a tendency to start new projects before I'm done with the old. One of the Benedictine vows is to “stability.” That can be a more sweeping rule than not just staying in one place and not being a gyrovague. For us it can be turning the compost into the garden year after year after year. Finishing the project. Being reliable.

Novelty can undermine stability. A culture is expressed in explicit rules and artifacts, and in unwritten values and courtesies. How long does your eye rest on someone before it becomes a signal? The MidWest does not agree with New York or with Dakar.

Mix everybody together--hooray for diversity and new ways of looking at things (and cool ethnic restaurants). Now, how do you signal someone that you want him to find a convenient moment to break off what he's doing and speak to you? Spell it out with new jargon? “Please grant me a class B3 interruption to your work.” What constitutes flirting? How can you communicate that you are in a great hurry?

At times like that diversity is obviously a burden. But I gather that it gets even worse. Can you fully trust someone whose values are different and with whom you have no shared history to give meaning to the nuances of language? Saladin and Richard shared martial values and could deal with each other on that basis, but neither would have successfully lived in a city ruled by the other.

Perhaps it is a blind spot in the articulate, that they sometimes think everything is defined in words or rules. But not everything is easily expressible; a constellation of little things can be huge. A man does not want his national home destroyed or even changed, because he can not even remember all the good things that go with it; just as he does not want his house burnt down because he can hardly count all the things he would miss.

And I haven't even gotten to some of the conflicts you get when introspective cultures meet unashamedly assertive ones.

The more diverse a society is, the more is going to have to be spelled out in detail--up to a point at which nobody can possibly know the rules. Beyond that, I suppose you have to have some kind of millet system, which isn't exactly the individual freedom ideal.

Advantage to not being famous

I have trouble remembering names. When people greet me on the street, I like to be able to remember who they are in time to reply. If everybody thought they knew me...

Problems in re-designing college

AVI posted a question: “I wonder what we would design for post-HS education these days if we were starting from scratch?"

This is a subset of a bigger question: how do we want to educate people?

There are some traps to trying to answer that one. When the animals wanted to appoint a king, the eagle said the criterion should be how high one can fly, the lion how loud one could roar, and so on—all with quite plausible explanations of the utility of the skill.

I thought back on our home school plans, and though I still think the outline was good, it wouldn’t fit everybody—in fact it didn’t.

For example, advertising and propaganda are so pervasive and skillful that I considered some lessons in persuasion techniques and elementary statistics (and the deceitful “average”) essential. The problem is that you need some analytical skill to parse out the tricks. Not a lot, but more than some people have. It is easier to use the rule of thumb that "all advertisers lie and all politicians lie and most newspapers lie about politics and social issues and whatever their advertisers don't like."

And not everybody is going to agree on the contents. Back in the day European nobility learned dancing, reading, some arithmetic, and fighting: Lots of practice with the fighting. They needed it. We’re lucky enough at this moment not to need quite so much fighting skill, but I’m not fool enough to think good luck lasts forever. Maybe other things are more immediately useful than my list.

We tried to make sure everybody knew some elementary carpentry, could repair their clothes (maybe even make them), accompany themselves on the piano, cook for themselves, drive, write a coherent paper, swim, factor a polynomial, know countries and geography, know the rudiments of another language… and a few other things as well. To my regret there was no ground swell of enthusiasm for differential calculus and marksmanship didn’t make the cut.

I like the idea of preparing people to teach themselves—or having readily available facilities ( Khan academy, book clubs, Sunday School, etc) for people to learn alone or in groups. (Some things you learn better in groups—discussion is critical.)

And I like the idea of breadth—getting a taste of a lot of different things. Who except lawyers, for example, graduates from college with any clue about the reasons behind property law, or who understands more than the vaguest outline of medicine? First aid, sure, but I’m not sure about any depth. And I wish philosophy were introduced earlier.

But at a minimum (to return to AVI’s question) the university should appreciate the differences in the nature of mastery of different subjects. A lot of courses of study don’t square off nicely in 4 year chunks.
