Civilizing barbarians

“Transparency and the rule of law will be the touchstones of this presidency.”

President Barack Obama, January 31, 2009

If a foreign government had imposed this system of education on the United States, we would rightfully consider it an act of war.

Glenn T. Seaborg, National Commission on Education, 1983

At least one black leader, a State Senator, has declared that we are now in a race war, blacks and their sympathizers vs. everyone else. She has no authority to declare any such thing, and she certainly does not speak for anything like a majority of African Americans, nor, I suspect, for anything like a majority of liberal intellectuals, but it is an astonishing thing to say.

We are not in a race war, but there are similarities to a barbarian invasion. We have a barbarian culture within the United States. The most common cause of death of black males is to be killed by another black male. There are other sub cultures in which homicide is common. Generally the barbarian culture does not interact with the majority of the middle class, but in so-called ghetto areas American citizens cannot avoid interactions with the barbarian culture. They live there, and they can’t avoid it.

More than forty years ago when I was a city official in the Mayor’s office, I was asked to sit in on a meeting with the precinct captain of a district that included both black middle class and some “Inner city” “ghetto” areas. The meeting consisted of the police officers and several black women who were tired of the lack of law and order in their neighborhood. The captain explained that he had no more resources: he had patrols on overtime as it was. There was nothing to be done. I offered to send some of the Metro units in. These were elite police patrols who strictly enforced the law.  I warned the ladies that if we sent them in, they would come down hard on all criminal activity they saw.  All of it.  The ladies said that was very much what they wanted.

We sent some of the elite Metro units into the neighborhood. They began enforcing the law as they had been trained: not as community police, but as strict enforcement officers looking for good arrests. This was before Wilson’s “Broken Windows” theory became widely known, but I knew Wilson, and this was in that spirit: you don’t ignore minor infractions because that leads people to think you will ignore major ones.

The experiment lasted about a month, and the ladies reported they were really surprised at how much better conditions were; but there were black leaders who claimed that the district was being overpoliced. The LA Times talked about the invasion of the police. The mayor told me to get the Metro units out of there. Things went back to where they were before I attempted to intervene.

This was forty years ago, after the Watts riots but before the later Los Angeles riots.

The cure for barbarians within the gates is to educate the barbarian children. Humans are not born civilized. They acquire civility by living in civilization, and they learn it as they grow up in it. In the United States we have had waves of immigrants from areas with entirely different cultures, some from more civilized cultures than ours, but many from less, and few in which civilization was based on freedom: American citizens act civilized because they are civilized, not from fear of apprehension and punishment. The Metro Unit wasn’t really the answer to those ladies’ complaints; it was just all I had to offer.

But the way to civilize barbarians is to do it in the schools, from the earliest grades on: enforcement of discipline, being polite, respectful deference to authority – not cringing fear, but respectful deference. But those values have to be instilled, and enforced.

I remember a song I learned as a child.

School days, school days
Dear old Golden Rule days
‘Reading and ‘riting and ‘rithmetic
Taught to the tune of the hick’ry stick

I think everyone I knew learned it. It’s a catchy tune, and it sort of described what we were doing in school. The hickory stick wasn’t much used, but it was legal for the teachers to use it. The Sisters in my first three grades had rulers which they were said to use freely (although I think I actually witnessed Sister Elizabeth Ann use hers no more than twice in the two years I was in her First/Second grade classroom). And the Three R’s were certainly what we were expected to learn. Reading and Writing and Arithmetic.

And when we moved to the country I was in a public school, again two grades to the room and about 20-25 pupils to the grade. This was out in the county in farming country, but we had the same textbooks that they had in Memphis, and we pretty well learned the same things: ostensibly reading, writing, and arithmetic. Of course reading included some real literature: no Dick and Jane, and alas no Cat in the Hat. I wish I had my Third Grade Reader. I have found the California Sixth Grade Reader, which I have edited and published as an eBook; our Tennessee Sixth Grade Reader wasn’t much different. Most of the same poems and stories.

But we were also learning to be civilized. To say “Ma’am” to the teachers, or call them Miss Dean or Mrs. Cooper and be courteous, and yes, obedient. We learned self discipline. You don’t run in the halls. You don’t hit girls (boys got away with a bit more roughhousing with each other, but you don’t hit girls). This is how civilized people live.

We were also learning that “dear old Golden Rule” as we were growing up. Explicitly, but that was just a lesson; but as a way of thinking. It was built into the stories and lessons, and the way we were expected to live.

When I was growing up the purposes of the schools was clear, and civilizing young barbarians was one of those purposes. Now this was the legally segregated South: the young barbarians I refer to were us, farm and country kids growing up in war time when adult supervision outside school was pretty rare.

It seems to have worked.

But as I understand it, that is no longer considered a purpose of the public schools, even though citizens with no children in those schools are taxed to pay for them. The teachers seem to believe – indeed many insist – that their task is not “indoctrination”, and it is not to “impose” a culture on their charges.

Of course it’s pretty hard to see what the system is supposed to do now: from observation a great deal of the system has become a ship which exists for the benefit of its crew, and its funding is not at all dependent on what it actually accomplishes. It’s surely not “the good old golden rule”, and from the results it’s hardly reading and ‘riting and ‘rithemetic either. It’s mostly to pay teachers, avoid any being fired for incompetence and few for anything else, and to pay for good benefits and pensions. The students are irrelevant. Yes, of course, there are dedicated teachers who hate all that, but they don’t run the system, and they aren’t paid in “released time” to be union officials. A ship which exists for the benefit of its crew.

And if the purpose of the schools is no longer to civilize young barbarians, that job is left to the parents and the churches; and we see the results of decades in which the schools are not

Dear old Golden Rule days
‘Reading and ‘riting and ‘rithmetic
Taught to the tune of the hick’ry stick

Young humans are not born civilized, and civilizations that leave the task of civilizing them to chance sow the wind.

We sow the wind. We are reaping the whirlwind.

I am told that more than 27 small businesses were destroyed by fire in Ferguson last night. I am also told that more than half of them were owned by minority owners (and I assume that minority includes Hispanic and Asian). The National Guard was present but not inserted to defend those businesses, but I do not know why they were ordered to stand down as the looting began. First there was pillage, then burning. When the barbarians come through the gates those are standard. If the Missouri State Senator is correct in pronouncing this their race war, we may see more.

Renewable energy ‘simply WON’T WORK’: Top Google engineers

Windmills, solar, tidal – all a ‘false hope’, say Stanford PhDs

By Lewis Page

Comment Two highly qualified Google engineers who have spent years studying and trying to improve renewable energy technology have stated quite bluntly that renewables will never permit the human race to cut CO2 emissions to the levels demanded by climate activists. Whatever the future holds, it is not a renewables-powered civilisation: such a thing is impossible.

Both men are Stanford PhDs, Ross Koningstein having trained in aerospace engineering and David Fork in applied physics. These aren’t guys who fiddle about with websites or data analytics or "technology" of that sort: they are real engineers who understand difficult maths and physics, and top-bracket even among that distinguished company. The duo were employed at Google on the RE<C project, which sought to enhance renewable technology to the point where it could produce energy more cheaply than coal.

RE<C was a failure, and Google closed it down after four years. Now, Koningstein and Fork have explained the conclusions they came to after a lengthy period of applying their considerable technological expertise to renewables, in an article posted at IEEE Spectrum.

The two men write:

At the start of RE<C, we had shared the attitude of many stalwart environmentalists: We felt that with steady improvements to today’s renewable energy technologies, our society could stave off catastrophic climate change. We now know that to be a false hope …

Renewable energy technologies simply won’t work; we need a fundamentally different approach.

One should note that RE<C didn’t restrict itself to conventional renewable ideas like solar PV, windfarms, tidal, hydro etc. It also looked extensively into more radical notions such as solar-thermal, geothermal, "self-assembling" wind towers and so on and so forth. There’s no get-out clause for renewables believers here.

Koningstein and Fork aren’t alone. Whenever somebody with a decent grasp of maths and physics looks into the idea of a fully renewables-powered civilised future for the human race with a reasonably open mind, they normally come to the conclusion that it simply isn’t feasible. Merely generating the relatively small proportion of our energy that we consume today in the form of electricity is already an insuperably difficult task for renewables: generating huge amounts more on top to carry out the tasks we do today using fossil-fuelled heat isn’t even vaguely plausible.

http://www.theregister.co.uk/2014/11/21/renewable_energy_simply_wont_work_google_renewables_engineers/

I do not know if they considered solar power satellites, which may be able to achieve the goal; I recall studies that indicate that it’s possible, although it would take a lot of SSPS systems. We will certainly have to move to some form of nuclear power in order to sustain the present population at anything like this standard of living.

Fortunately, probably not. I doubt the Russians want to rule a number of intelligent and hostile people and the Finns most certainly would be hostile. Ukraine is historically part of Russia, not merely an imperial acquisition.

Rosetta and Philae 

Dear Dr Pournelle,

I’m very surprised that you have not yet celebrated the soft(ish) landing of Philae from the Rosetta probe on Comet 67P (avg. 2.6 km dia.), after a 10 year flight and over 6.4 bn km travelled. Philae has performed better than 90% of its primary mission on its main batteries, but having come to rest in the shadow of a cliff, the solar-powered secondary batteries are not adequately charging, so additional, unscheduled tests cannot be performed (this may improve as 67P moves closer to the Sun and the intensity of the light falling on Philae’s photocells increases; at present it is about 330 m km away — beyond the orbit of Mars). ESA researchers are currently analysing the data collected from Philae, and we already know that organic molecules have been detected. You can watch videos and read reports on ESA’s web site, <http://www.esa.int>.

OK, I’m a European, and I’m really, *really* proud of what this consortium of nations has achieved with this mission. I’ve never felt so excited since my parents allowed me to stay up to watch the broadcast of the US Apollo 11 Moon landing.

And now I read that ESA/Airbus will be making the primary stage of NASA’s Orion rocket. 🙂

Best regards,

Alun

You ought to be proud. It was a magnificent achievement. I probably should have commented but I have been swamped lately, and there was little I could say other than Congratulations!The final location of the probe was unfortunate, but getting onto the comet at all was wonderful.  I’m still absorbing the information.

I recall way back in the Eisenhower Administration there was an effort to have a public law to the effect that there could never be more employees of the Department of Agriculture than there were farmers and farm workers. That failed every time it was proposed.

I would think, though, that given the financial circumstances we could eliminate the entire group of inspectors and supervisors who enforce the regulation that stage magicians must have a Federal license to keep rabbits, and anyone who sells rabbits as pets (although not if they sell them to eat or to feed alive to serpents) must have a Federal license. Perhaps when we are rich again we can afford such people but surely we can do without them now? Incidentally if a stage performer slays and eats alive a rabbit he does not need a Federal license; only if the rabbit is used as a pet in a performance. And grown people enforce this.

The lesson is clear. There are a lot of Federal jobs that we can spare in these troubled times; many people doing things that we can do without, certainly that we do not have to borrow money to pay for. Why is there never such discussion in debt ceiling debates?

TSA – another astonishing gaffe

 
 

Message Body:

Dear Jerry,

I am sure you have read this, and probably had a flood of email about it too, but there is a story in today’s LA Times about a man making flights with someone else’s expired boarding pass and no valid id. He was detected (but not arrested) after passengers ‘complained that the man seated in 3E reeked of body odor’. I find it difficult to comment on this – I am filled with outrage over the indignities I have endured in the name of flight security, and incensed that this man was allowed to travel (apparently many times) like this.

PS I find the new site layout interesting. It is very good for reading the most current stuff, but when I went back and tried to reread a whole week I found myself wishing that the order was reversed.

 
 

PPS I probably should have done a separate email on this, except that my comment is so slight. Analog are running a serial (Energized) by Edward M. Lerner on Space Solar Power (and terrorists hijacking the system and frying various industrial complexes on earth). I suppose it is a cautionary against this technology, although I haven’t read the final installment yet.

 
 

I am trying to figure out how to set things up as we used to do. Some read this daily or several times a day. Others once or twice a week. Clearly the old order was better for those who come here at intervals not several times a day. We will see what we can do. There must be a way.

It’s very hard to turn a solar power satellite into a sun gun. That was one of the first things we thought of back in the original Boeing proposal I worked on. A long time ago. Sun guns require high energy densities and the ability to keep the beam collimated when it is off target. That’s pretty hard to do even if you are the legitimate owner of the SSPS, and we don’t think hijackers can do it at all, whether they hijack the ground control room or actually get to space… As Wina Sturgeon asked me once, the only way I know of to make a nuclear power plant explode with a nuclear blast is to smuggle in a nuke…

As to TSA and its kabuki security theater, why are you surprised?

I like the new design layout… but is there any chance you could continue using the old parch5.jpg background image – seems like it’s been around long enough to be a tradition.

Chuck

 

It can be done, but the consensus around here is that it comes out weird colors depending on what you are looking at it with. I always saw it as parchment, but many saw an odd pink, and it changed from time to time. I like the grey for readability, and it’s probably time to give that a try. JEP

Thanks for the kind words. We are trying. I really am trying to come as close as possible to what we have been doing, in part because I sure don’t want to learn something new.

An unidentified reader provided the following:

 

“Instead, just post reader mail as it comes in along with your own comment – each in a separate post. I would think this would be simpler for you, too, by eliminating the compilation step.”

 

Please don’t do that. I know that many blogs allow reader comments to appear instantly. It is not necessarily a desirable ‘feature’. I like the idea that letters from your readers, mine or anyone else’s, appear because YOU read them and you, personally (It is YOUR blog, after all.), thought that they were worth passing along. If you feel that my letters, any or all, or those of your other readers that you choose not to publish, for WHATEVER reason, are better suited to the ash bin of history than to your blog, fine.

 

After all, I think that is what attracts many to your site: your personal involvement.

 

Also his suggestion that you comment on ALL of your reader mail seems mighty liberal with your time. Who was it that starved to death answering reader mail? We don’t need you as another example.

 

Anyway, thanks for your efforts.

The only way to comment here is to send me mail. I get far more mail than I can publish. Some is quite good enough for publication, but it is part of a flood on the same subject. Some is flattering but doesn’t show any new perspectives. Some just doesn’t strike me as appealing to the readers. I select what I think is interesting, and the result is that I think this is one of the most interesting mail sections on the Web. We have a wide variety of readers with great perception and often great expertise.

While I try to read all the reader mail, I am sometimes a long way behind on that. I do have other things I have to get done. I wish I could comment on all the mail I select, but I often can’t. We does the best we can…

Site Redesign

 

Jerry,

 

As a longtime reader, I can get along with everything I saw on the new page, except that the new page puts Saturday below Sunday. Personally, I can’t stand “blog order” – we read from the top down, and chronological order should run from the top down, not from the bottom up.

 

If the new software is not capable of placing the entries in logical order, the next best thing would be to recreate the “Monday – Tuesday – Wednesday” etc. links that were at the top of the old page, so readers could click a link and read Saturday first, then return to the top and click to read Sunday, instead of having to scroll futilely about the page to read in chronological order.

 

Best wishes for a speedy recovery.

 

Respectfully,

Tom Brendel

 

We’re looking at this but I am not sure what to do. The calendar over there on the right is live, and it will let you go to a particular day; that may be the best we can do. For the moment we’re going to stay with what we have, but that doesn’t me we can’t revise once we see just how this works. For the moment I’m trying to get used to using what I have. Thanks.

There is a trend in this direction. After the Rodney King incident it will not happen in Los Angeles; and I would think that the 14th Amendment give Congress ample power to defend the rights of citizens to monitor and report the actions of the local police. That is, after all, what Civil Rights is all about. Interesting that Illinois thinks that is not needed.

Space Solar Power

 

Hello Jerry,

 

“I do know that when we did the Boeing study one of the tests was transmission of power through atmosphere using Goldstone as the transmitter to a rectenna; the efficiency of the operation, that is, the ratio of usable power out of the rectenna to the input power at Goldstone was about 90%.”

Actually, the recent spate of YouTube videos on the subject say that the rectenna produced an output of around 82.5% of the INCIDENT RF energy.

 

The Goldstone transmitter for the Venus tests produced around 450 kilowatts of rf. The the input power from the grid that was required to produce the rf was not reported. The best klystrons available today produce around 700 kw at an efficiency of 44% (current state of the art). The ones available in 1975 were considerably less efficient. Even granting 40% efficiency, the Goldstone transmitter tests required at least 1.2 megawatts of power from the grid to produce the 30 kilowatts from the rectenna.

 

Some (maybe most) of the newer proposals do away with the thousands of huge klystrons in orbit and replace them with large numbers of lower power solid state modules driving elements of a phased array. Here is a paper listing several alternatives (interestingly, the paper proceeds as if the down link were buildable).:

 

http://www.scribd.com/doc/54333065/2/History-of-Wireless-Power-Transmission

 

It includes information on the Goldstone tests, by the way.

 

One of the tables in the paper lists rudimentary specs for the downlink antenna. The number of transmit modules range from 97 million (NASA/DOE with 185 w/module) to 3.5 billion (Old JAXA proposal, with 1 w/module). The NASA/DOE proposal with a downlink at 2.45 GHz, a 1 km transmit antenna, and a 1 km receive rectenna is not believable; the ‘cold equations’ of aperture vs beamwidth don’t allow it. A 1 km diameter transmit antenna @ 2.45 GHz WILL NOT produce a 1 km diameter beam at a distance of 22,500 miles.

 

All of this sort of begs the issue: Antennas are not infinitely scalable, any more than are telescopes. At least not buildable ones. It is a little like using the specs for Hubble (8′ diameter, resolution .05 arc seconds) as ‘proof of principle’ for a telescope with a diameter of 50 million feet so that we could resolve 1 mile surface features on planets orbiting Alpha Centauri. In theory, that would work; in practice, we aren’t building a 50 million ft diameter telescope any time soon. Neither are we building, stabilizing, and maintaining a geosynchronous phased array antenna a couple of kilometers in diameter with a billion (more or less) driven elements any time soon.

 

Bob Ludwick

 

Thank you. I haven’t looked at the data in decades. I can only say that a team of us, all experienced, with a span of expertise we thought more than adequate, concluded after a lot of hard work that SSPS was economical once the capital costs – considerable capital costs – were paid. General Graham had a similar experience with his team of High Frontier staff and volunteers. So did Lawrence Livermore. I think that conclusion is still viable. Space Solar power isn’t easy – that’s one thing we have learned about space and with a vengeance, nothing is easy – but not easy doesn’t have to mean physically or economically impossible. I do not believe the dream is dead.

Benign incompetence or competent malevolence

 

Hello Jerry,

 

“One may draw any conclusion one likes.”

 

True, but the sign being waved by the SEIU half of the Obama/SEIU mutual admiration society, combined by the observed behavior of the Obamunist half over the last two and a half years, should surely influence one’s conclusion a bit, I would think.

 

I suppose that the conclusion would also depend upon whether one thinks that stamping out a capitalist representative republic and replacing it with a socialist/Marxist/communist/fascist tyranny is benign or malevolent. (I know, socialism/Marxism et al are not identical, but one or more of them would be appropriate descriptions of ALL of the Obamunist actions since they took command–literally–of our country.)

The View from Chaos Manor

THE NEW VIEW

 

This is a production experiment: that is, due to the imminent closure of my wonderful old ISP that Brian and Greg ran and which they were able to tweak with customizations and accommodations to my crazy style, we can’t go on as we have been. Microsoft hasn’t supported FrontPage, which as far as I am concerned worked just fine for what I was doing. Apparently I can’t go on using it with a new ISP without the tweaks that Brian and Greg did for me. All this is being handled by friends and advisors, and after some discussion we’ve chosen WordPress. I’ve done some experiments using a dummy site. This is the first “production” post. It’s as plain as it can be. I’ll start playing about with added features, graphics, customized lines, and other conventions as time goes by; first step is to get the darned thing up and running.

 

I compose all these in Word. I am then to use Word to “publish” this through commands built in to Word 2007. I expect to upgrade to Word 2010 fairly soon, but for the moment this will have to do. Each post becomes a separate file and log entry, as opposed to the old FrontPage system in which each week became a file that was updated, sometimes several times a day. I am not sure how that works here: I much prefer to be able to go in and make corrections, add notes, perhaps add links, note objecti0ns or corrections, and such like as I have been doing. It’s my intention to make as few changes in your reading experiences as possible, and what changes are made should be improvements. I suspect that won’t happen the way I expect, but we will see.

 

I’d be happier about the adventure if I could just shake off whatever seems to be afflicting me this week, but that’s another story. Meanwhile it’s a new adventure. I know I have been way behind the times in modern blogging technology despite the fact that I can make a fair claim to being the first blogger. I didn’t call it that because I still think the term is ugly, but I certainly was among the first to have an open daybook and log.

 

For the few people who have wandered in to here and have no idea of what you have found, the old Home Page for Chaos Manor sort of tells that story. I am not dead sure how we link these two places, since only one can be called www.jerrypournelle.com and someone other than me long ago grabbed www.chaosmanor.com and hasn’t let go. We’ll work something out.

 

 

That was an attempt to insert a break line. It’s not one I’ll choose. Back in the early days of this daybook I used different line images for different kinds of breaks, but that became tedious. I then went to a line of equal signs, but Word like to turn those in to a full line, and I am not sure how WordPress will display them. Probably nothing for it but to try and see.

Satellite Solar Power Reconsidered

 

One of the results of my Space-X visit is the discovery that Elon Musk has concluded that even if the costs of putting solar power collectors into space were met, the operating costs of solar power satellites would make the entire thing uneconomical. This is completely contrary to the conclusions reached in the original studies conducted by Boeing, the NASA SSPS project study, and the consultants working with General Graham’s High Frontier.

 

I do not know what studies Musk relies on for this conclusion. A quick on-line search on SSPS operating costs reveals this, which isn’t anything I would rely on, so I assume there are more data I haven’t seen. I do know that when we did the Boeing study one of the tests was transmission of power through atmosphere using Goldstone as the transmitter to a rectenna; the efficiency of the operation, that is, the ratio of usable power out of the rectenna to the input power at Goldstone was about 90%. This was in the early days of collimation, and we may have assumed some improvements in focus – obviously the beam tested was horizontal across the desert, rather than vertical, but the point was to measure atmospheric effects and the distances chosen were to simulate the atmosphere – but the tests were done and the measurements made. There were also some tests of focus and steering. Clearly you can’t steer a power beam by mechanical movements of the transmitting antenna. Anything that uses reaction mass is prohibitively expensive. SSPS designs used electronic means of collimation (focus) and steering, and indeed the energy for the collimator comes from energy received on Earth, then retransmitted to the satellite: the point being that if the power beam walks off the rectenna, the collimator loses power and the beam disperses. That, at least, was one of the designs we worked on.

 

All this was long ago, and I don’t recall all the details; but the conclusions were agreed to by some pretty high powered people, and the operations costs of the power system were carefully considered. This was one of my areas of, if not expertise, then at least competence, and I didn’t find any absurd assumptions in the models we use.

 

Thus it was a bit disappointing to find that one of the successful space entrepreneurs doesn’t believe SSPS is economically feasible. I wasn’t given the reasoning or access to the study numbers, so I’ll have to rethink all of this on my own. I think he’s wrong. I know we worked hard not to omit significant operations costs in the models we did at Boeing, and there were some pretty good Operations Research people involved in the NASA SSPS study and conference, and of course Arthur D. Little did some serious OR studies of the SSPS concept.

 

 

This will have to do for the first day’s ‘production’ view. Now to do a production Mail.

 

It is after midnight. I have made a few additions to see if they come up properly. This has been a reasonable day’s work. Suggestions for layout changes, decorations, and other improvements are now open. Mail and View will be the primary pages but I do hope to create some reports and specials too.

And good night. The lines aren’t working. I was told that there were ways to insert lines, but I haven’t found them yet, Ah well. Not a bad beginning I hope
