June 30, 2008 There was a lively if inconclusive discussion of entropy (of all things) over the weekend. See last week's mail. I was talking with Steve Cram, the new Chancellor of the University of Sunderland after the ceremony on Friday, and I suggested he get the message out that "Sunderlanders don't give up!" He answered "Well, they don't!", but my response was "They do in the classroom" and explained what I meant. 80% of anything worth getting is determination, and that means don't give up, particularly in academics.

http://www.nytimes.com/ == Probably there is some hidden selective advantage to not having children. Alternatively, East Asians appearing to be more fit than Caucasians, this is evolution's way of clearing the way for the stronger, through a sort of action at a distance. Defeated dogs have evolved the strategy of rolling over and aring their throats; perhaps we are seeing the racial equivalent, mediated by the racial unconscious.

Striking exactly one century ago, Tunguska represented a wake-up call to the hazard of cosmic impacts... or it should have. But it landed in a nearly uninhabited region, and the chaos of the First World War, the Russian revolution, and the ensuing civil war prevented scientists from quick follow-up, to visit the site and assess the nature of the impact. Until quite recently the explosion was generally attributed to the impact of a comet, which was understandable when comets were the only objects we knew that intersected the Earth's orbit. Now we recognize the impact signature of a stony (not icy) object, a result that is also consistent with the extreme rarity of small comets relative to stony asteroids. Below is a much more detailed history of the Tunguska event, just published in the special impact issue of Nature that marks this centennial celebration. David Morrison ============================= Duncan Steel // Published online 25 June 2008 | Nature 453, 1157-1159 (2008) PLANETARY SCIENCE: TUNGUSKA AT 100 "Sooner or later, it was bound to happen. On June 30, 1908, Moscow escaped destruction by three hours and four thousand kilometers - a margin invisibly small by the standards of the universe." So begins Rendezvous with Rama , a 1972 novel by Arthur C. Clarke in which mankind learns the hard way about the dangers posed by incoming asteroids. The 2077 impact in northern Italy that Clarke goes on to describe is fictional: the 1908 blast was real. The early morning of 30 June 1908 saw, in an area around the Stony Tunguska river, the most explosive cosmic impact in recent history, hundreds of times more powerful than the atomic weapons set off over Hiroshima and Nagasaki. And yet, in part because it happened so far from civilization, and in part because it left no crater, it has not always been recognized as such. For decades it existed in a strange realm between science and pseudoscience, blamed on antimatter, black holes and alien spacecraft as easily as on a very fast bit of interplanetary refuse, and developing a mystique that has seen it associated with everything from energy drinks and rock bands to military missiles and The X-Files . The approximate site of the blast's epicentre is now marked by a totem pole that researchers have dedicated to Agdy, the god of thunder in local mythology. Getting there is quite a trek, but the fascination of the site still draws an intermittent stream of scientists to the remote wilderness about 1000 kilometres north of Lake Baikal; they leave offerings at the totem pole to commemorate the trek. In the years directly after the blast, though, no one came at all. The first researchers did not arrive until the 1920s. That does not mean there was no significant contemporary evidence to bring to bear. Siberia was and is an empty place - but a blast which, had it happened over Chicago, would have been heard from Georgia to the Dakotas, still drew a lot of attention. In the days following the blast, A.V. Voznesenskij, the director of the Irkutsk magnetic and meteorological observatory near Lake Baikal, began collecting accounts that are vivid with detail. There are people being knocked off their feet, a man needing to hold onto his plough to avoid being swept away by a powerful wind, the feeling of great heat "as if my shirt had caught fire", herds of hundreds of reindeer being killed, trees set alight by the radiance of the fireball only for the flames to be snuffed out by the subsequent blast wave. And the reports are unequivocal on the source of the blast. G.K. Kulesh, head of a meteorological station at Kurensk, 200 kilometres from the epicentre, told Voznesenskij that: "A meteorite of very enormous dimensions had fallen." (G.K. Kulesh: "There appeared in the northwest a fiery column Š in the form of a spear. When the column disappeared, there were heard five strong, abrupt bangs, like from a cannon, following quickly and distinctly one after another Š there had been a strong shaking of the ground, such that the window glass was broken in the houses Š It is probably established that a meteorite of very enormous dimensions had fallen.") In the days after the blast, much of Europe experienced eerie 'bright nights': readers wrote to The Times in London, remarking that its columns could be read outdoors at midnight. Polarization measurements are consistent with this being due to sunlight scattered by dust in the very high atmosphere; observatories recorded increased atmospheric opacity and scattering across the Northern Hemisphere. This spreading dust may have been due to a plume ejected backwards along the incoming object's path by its explosion. Such plumes were seen on Jupiter when the fragments of Comet Shoemaker-Levy 9 slammed into it in 1994; hydrodynamic modelling by Mark Boslough and his colleagues at Sandia National Laboratories in Albuquerque, New Mexico, indicates that a similar terrestrial plume could be expected for an impact such as that at Tunguska. There was, however, one good reason to doubt that a small asteroid was involved: the belief of the time that this would deliver a valuable hunk of iron to the surface. The Russian meteorite hunter Leonid Kulik, who led the first expedition to the epicentre in the 1920s, obtained funding from the Soviet government on the basis that he would find a valuable ore body there. But when he reached his goal in 1927 he found no metal. Nor did he find the crater that an impact was expected to leave. (There are now claims that nearby Lake Cheko might be such a crater, but these are widely disputed.) There were clear signs of violence - trees knocked flat over a vast swath of land - but no big hole in the ground. What could have happened? In 1930, US astrophysicist Harlow Shapley suggested that the lack of a crater was due to the nature of the impactor. If it had been a comet, and comets were light and fluffy, then it would have exploded at altitude. This idea persisted for decades: in 1982 some planetary scientists were willing to postulate the extraordinarily low density of 3 kilograms per cubic metre in order to explain Tunguska in terms of the blast from a disintegrating comet. Other explanations were even more far fetched than candyfloss comets. Soviet science-fiction author Alexander Kazantsev realized, as Shapley had, that the best explanation involved an explosion at altitude, and suggested in 1946 that a nuclear-powered alien spaceship exploding just before landing might have been the culprit, an idea taken up eagerly and earnestly in the following decades. A more scientifically promising possibility was naturally occurring antimatter, a suggestion made independently by various people at various times. In 1940, Vladimir Rojansky of Union College, Schenectady, NY, suggested that some meteors and comets might be made of antimatter - 'contraterrene' matter in the terms of the time - and that their odd behaviour might be detectable. (More than 30 years later Rojansky suggested that it would be worth checking if Comet Kohoutek was one of the antimatter ones.) In 1941, Lincoln LaPaz of OSU in Columbus published two articles in the magazine Popular Astronomy that argued that large terrestrial craters and the craterless Tunguska explosion were both due to antimatter meteors; he later wrote to the Soviet Academy of Sciences suggesting a search for anomalous isotopes at the site. More than a decade later, Philip Wyatt, a graduate student at Florida State University in Tallahassee, and Boris Podolsky, author of a famous paper with Einstein exploring apparent paradoxes of quantum mechanics, went to a movie in which antimatter featured. Podolsky pointed Wyatt towards Rojansky's 1940 paper and suggested he look into the impacts idea. Wyatt - now the chief executive of the Wyatt Technology Corporation in Santa Barbara, California - says that he was "mostly interested in looking for residual radioactivity" and published some ideas on the subject in Nature. "Other explanations were even more far fetched than candyfloss comets." This notion was expanded on by three eminent American scientists (including 1960 Nobel Prize winner Willard Libby and Clyde Cowan, co-discoverer of the neutrino) in 1965. Libby, the original developer of the carbon-14 dating technique, found support for the idea of an antimatter impact from what seemed to be an elevated carbon-14 level in tree rings around the world in 1909, suggesting that significant quantities of the isotope had been created by radiation given off when the antimatter annihilated itself on contact with the thicker layers of the atmosphere. Even at the time, though, there were good arguments against the idea: among other things, the first gamma-ray-detecting satellites were not seeing the tell-tale radiation from antimatter annihilation elsewhere in the nearby cosmos. Even more extreme, in 1973 two University of Texas physicists suggested that the cause was a black hole passing through Earth. This was nothing if not fashionable: miniature black holes had just been postulated by Stephen Hawking as after-effects of the Big Bang. Again the explanation was incomplete and its implications - an exit on the other side of the planet, and a seismic signal lasting well after the initial impact - unobserved. Similar caveats apply to the intriguing hybrid idea, aired as recently as 1989, that the culprit was a deuterium-rich comet turned into a hydrogen bomb by the heat and pressure of its arrival in the atmosphere. Another approach has been to suggest that, despite the straightforward implications of eyewitness accounts of a bright object zipping across the sky, the source of the blast was in fact beneath the surface. A recent example is a claim that it was due to a 10-million-tonne belch of methane that subsequently exploded high in the sky. Others see a geophysical source involving peculiar tectonic behaviour. The fact that such ideas were entertained (and still are, in some circles) speaks both of a certain fascination with the fanciful and the abiding need to explain that confusing lack of a crater. The fact that, by the 1960s, various craters around the world had been accepted as meteorite strikes meant that the anomalous lack seemed all the more confusing. In 1993 that confusion was allayed, at least for most people, by Chris Chyba, Kevin Zahnle and Paul Thomas. With the help of computer simulations derived from nuclear weapons' tests they showed that a solid, stony object about 50 metres across - the most likely sort of thing in that size range to hit the Earth - would not be expected to reach the ground. There was no need to invoke weirdly low cometary densities - at the relevant speeds the shock wave generated within a solid body as it slams into the atmosphere would rip up an everyday rock just fine. Formations such as Meteor Crater in Arizona are left by tougher impactors made of metal; the shock waves don't get the better of them until they've reached the ground. A similar explanation was arrived at by Jack Hills, working at Los Alamos National Laboratory in New Mexico with Patrick Goda, and both teams had been to some extent pre-empted by a Soviet team led by V.P. Korobeinikov, the work of which had not been widely appreciated in the West. These various models led to an estimate that the blast was equivalent to about 15 megatonnes of high explosive - bigger than all but the very largest thermonuclear weapons. However, work by Boslough indicates that the energy required to fit the observed phenomena could be rather less, around 3 to 5 megatonnes. That analysis assumes that the impactor was a stony asteroid - but a comet is still a possibility. In 1978, L'ubor Kresák suggested the Tunguska impactor was a fragment of Comet Encke. The peak of an annual intense meteor shower associated with dust from Encke occurred around 30 June 1908, but because the meteors arrived from the direction of the Sun, the shower would not have been visible to the naked eye. What the eyewitnesses said about the direction of the Tunguska projectile is consistent with that idea. An analysis of many hundreds of possible pre-impact orbits for the object published in 2001, by a team that had been led by the late Paolo Farinella, indicated that an asteroidal orbit was more likely than a cometary orbit - but using that paper's definitions, Comet Encke, which takes just 40 months to orbit the Sun, has an asteroidal orbit. Another line of evidence, suggested in 1977, was that a comet might explain the carbon-14 signature reported by Cowan in the 1960s; a comet in space might naturally be thoroughly irradiated. The question of what the object was is not purely academic. If Tunguska was indeed a 15-megaton event, it was rather unlikely - such things are expected only every 1,500 years or so. That calculation, though, assumes that the flux of near-Earth objects is constant over time. If the population of near-Earth objects is replenished from time to time by the break-up of a comet, then shortly after that break-up, impacts from Tunguska-sized fragments will be more likely. Earth may suffer near misses from Tunguska's dark and stealthy cousins every time it passes through Encke's dust stream - fragments too small to be easily observed, but big enough to cause quite a mess if they hit. In Rendezvous with Rama, Clarke's solution to the threat of impacts was an asteroid search programme aimed at ensuring that such a catastrophe could never occur again: he called it Project Spaceguard. This became the name of a real-life programme, and that search continues. But 50-metre objects are too small to spot far in advance of their impact. So although another Tunguska coming out of the blue is not a likely event in any given June, it is not out of the question. Duncan Steel is an astronomer and writer after whom Arthur C. Clarke once named a robot. -- +++ NEO News (now in its fourteenth year of distribution) is an informal compilation of news and opinion dealing with Near Earth Objects (NEOs) and their impacts.

July 1, 2008 Subject: Citing Need for Assessments, U.S. Freezes Solar Energy Projects Dear Jerry, Thought you might be interested in this in the context of energy strategy. The reason for the freeze is that the 130 pending applications to use Federal land for solar power developments have requested more than a million acres of land. Professor Ausubel of Rockefeller University caught a lot of flak last year for pointing that solar power development would require huge land areas. It seems like that era has arrived as the BLM has applications that account for nearly 1% of the land that it manages. http://www.nytimes.com/2008/06/27/us/27solar.html?ref=science Solar energy developers need to realize that they're subject to the same requirements and restrictions as any other land use including the requirements of the endangered species legislation, etc. The unstated reason for the freeze is that the BLM probably doesn't have enough scientific staff to properly vet this many large scale applications. Take care and don't strain yourself. Bob Kawaratani Tokyo, Japan The Solar Constant remains, uh, well, constant. Moreover the Sun doesn't shine at night, nor does it stay still in the sky, meaning that either your solar collector array has to be steerable in at least one axis and preferably two, and even then you have to have a BIG array. The numbers don't lie. One good use for ground based solar is as Ed Begley uses it: local collectors maintained by the local citizenry. I recall the night the tree fell about a block from Ed's house: his was the only house with lights, and Rochelle was cheerfully watching TV while everyone else cursed the darkness. This avoids transmission costs and losses. Of course it costs in batteries: one reason for better battery technology, since the much more efficient pumped water storage is not likely to appeal to house holders. (Imagine two swimming pools, one above the other, with water pumped to the upper one when the sun is shining, and flowing back down through turbines at night...) Big solar arrays are best put in space; the antennae for receiving the power from space are very small compared to the collectors, and are best put in deserts. It's a lot easier to evaluate their environmental effect, although I recall one EPA official who, told that the energy spill half a kilometer from the edge of the receiver array would be less than the quantum energy required for chemical reactions, said "Well, I don't know. It could be dangerous." I expect she is now high up in the Global Warming hierarchy. == Power grid capacity for charging electric cars Jerry, Regarding the correspondent who stated "As an aside, the power grid doesn't have the spare electricity generating capacity to support electric cars anyway. And there's no indication the greens will ever let it be built" you might want to point him here: http://www.knoxnews.com/news/2008/jun/17/tva-plugging-electric-cars/ TVA plugging electric cars Batteries would need to be charged at night, with excess capacity NASHVILLE - TVA Chairman Bill Sansom told a panel of congressmen Monday that the agency could easily handle future demand from electric-powered cars and offer a 20 percent discount - so long as batteries are charged at night. etc. Regards, Bill Ghrist == If McCain's prize really did lead to a battery capable of replacing the internal combustion engine, chances are that arrays of the battery would provide a practical way of storing the output of solar power plants and wind turbines for later use -- and that in turn would make it possible to use solar and wind power for base-load electric power generation. Given Obama's distaste for all energy solutions other than solar and wind, his opposition to McCain's proposal is kind of moronic. Paul Danish I may be excessively dense (or suffering from brain damage but I have never understood the frantic dismissals of McCain's battery prize. I can well agree that this may not be the best technology for a prize -- that is, there may be other technologies more deserving; or that this is the wrong amount; but what I have heard is sheer contempt as if the very proposal shows McCain to be a fool. This from some of my readers (not too many, Deo gratia) and also from public figures who nominally support McCain and ought to know better. More efficient batteries would be extremely useful for encouraging much more distributed solar electric collection (the Ed Begley Jr. Model; as Ed notes, with $120 and above oil, his present system is close to economic efficiency, and there is a lot of convenience in being off the grid and independent of power failures: think of his house as being run on a gigantic UPS). More efficient batteries that would raise the practical range of over-night charged electric cars to 120 miles or more would have a real effect on the way to do and plan transportation. More efficient batteries would go well with more nuclear power. McCain may or may not have the prize level right, and I would have chosen a different technology area for my first prize proposal, but I'm all for better batteries, and at $300 million he has chosen a level that may have a great effect on technology development while keeping the cost very low. We lose $300 million every day in accounting areas in the Welfare Departments. ============ Subject: asparagus I have little hope for a Mars colony if what it grows is asparagus. R H Will broccoli do? On a serious vein, I want to see a Lunar Colony first; I want to be sure we know how to make do in space.

Alternate POV? Some of the things he has/is interested from his "Letters from England" are interesting. Usually, I skip the following-up of his links en-masse. The problems of Britain haven't seemed to be the problems of America, they still don't. Do you post his mushgns as word of warning to an Empire greeting the setting sun? I can't afford, nor do I have the connections to retire to Ceylon and watch the world go 'round... Socialism/Communism is the bug-bear that boys have long cried wolf about; the demon seems about to blow my house of straw down. I guess I could say that a house of straw is all my parents have afforded me to have, but then; my parents are the village... But, we have our own Magna Carta to deal with, is that why you consistently put Dr. E's worries up on public display? The American Revolution is now half as old as the "English Revolution?" Something like Moore's law on a different order of magnitude? Constitutional (Parliamentary) Law is as burdensome, if not more so, than the first time we broke with it? Can we as Americans "lead from the front?" We weren't a Constitutional (parliamentary) Monarchy to begin with, but we always appear to be one whenever Presidential elections roll around. I suppose that was a question the framers attempted to address when they drafted that wonderful document; does the proletariat really need to vote? Are they better off not voting, they know what is best for themselves, or there be some amongst them that have the miraculous ability to lift themselves by bootstraps? Marx answered it with the answer that they know what is best for themselves. We've fought that debate on the battlefield, Marx lost. Or has he? Synopses. I've lost track of my argument... Is Dr. E an ex-patriot? As an ex-patriot does he have any leg to gripe on if what he is seeing is America two hundred years hence? I still enjoy reading his synopses of the links he provides. If he's a Brit-cit, I feel for him. They are the last hold-outs on the EU, unless you count the Irish.... On to Duodenum Tabularum, et al.. Jurisprudence, I hope my failure to research Juris and Prudence doesn't fail me here... Monty is always witty if not downright funny in his expose (accent agu) of Dr. E at times. That seems to be the one strength left in American governance. Jurisprudence. My research fails me, how are judges appointed/elected or selected in British jurisprudence? Is that important to the discussion? --------- On discussions: A thought plagued me this afternoon; those thousand monkeys typing out the Bard. Does it matter if they manage to type out a coded version (simple substitution or Enigma device) of his plays? If so, wouldn't that bring the odds down a bit? Does the chronological order of plays matter? Actor lines (i.e. get one complete line correct, out of order, out of play, same encryption.) Are we looking for big complete miracles or small discrete miracles? --pate I remain interested in England, and Dr. Erwin is kind enough to put together a pretty good synopsis of what's going on, and from a view that I respect. This is an eclectic journal... Besides, I like his views. ========== I have a long mailing summarizing a great deal about Global Cooling. It's long enough that I did not want to put it in mail, so I have made it a REPORTS page. You will find it here.

Wednesday,
Reply I'm an American teaching at a university in northeast England. I came originally from Riverside, California, and moved around America, working in the defense industry, before doing a PhD in neuroscience and going to England to teach computing (and do my research). I collect together a few UK news stories each week so Jerry can have some idea what's happening elsewhere. I try to make them relevant to problems America is wrestling with--health care, education, the economy, managing a country, religion, politics, kids growing up, political correctness. Learning by experience is expensive, so why not make it other people's experience that you learn from? -- Harry Erwin, PhD "If you can't be a good example, then you'll just have to be a horrible warning." (Catherine Aird) == And a representative reader comment A few comments In response to the letter from pate, which questions the relevance of "Letter From England", I disagree. I think its essential to look around the world to see how other countries deal with issues. We share a language, legal system, culture, and a lot of history with Britain, so I think their news is very interesting. A good example is health care. They have socialized medicine, and our liberals (sorry, progressives) really want us to copy their system. Well, not exactly copy, they actually won't name a country with socialized medicine we should copy. They won't even say socialized medicine, they say "Health Care for Everyone", whatever that means. Britain tries hard to make socialized medicine work, but they still have major problems. Like finding a dentist. The liberals don't want us to see what they plan for us, so we must examine other countries to see how their version of socialized functions. Britain has been controlled by the Labour Part for years, and they say they believe in Global Warming. But when push comes to shove, they build more coal fired electrical facilities. Never let saving the planet get in the way of keeping your job. My ancestors came from England, and I am an anglophile. Still, we should keep an eye on other countries. Randy Lea ========== Hello Dr. Pournelle, Paul Graham has written an interesting -- and I think important -- essay about secondary education in American society. http://www.paulgraham.com/nerds.html He starts out to answer a question -- "Why are nerds unpopular in secondary schools?". But, he ends up describing the social structure of American secondary schools from the inmate's -- er student's -- point of view. Along the way he touches on how and why our schools got so bad, and on the origin of the "teenager". His essay is long but worth the time if you have an interest in the subject. <excerpt> When we were in junior high school, my friend Rich and I made a map of the school lunch tables according to popularity. This was easy to do, because kids only ate lunch with others of about the same popularity. We graded them from A to E. A tables were full of football players and cheerleaders and so on. E tables contained the kids with mild cases of Down's Syndrome, what in the language of the time we called "retards." We sat at a D table, as low as you could get without looking physically different. .... </excerpt> Best regards, Clyde Wisham **** "One man's "magic" is another man's engineering. "Supernatural" is a null word." -- R. A. Heinlein **** In high school I sat with others of the science club and chess club; but also sitting with us was my friend J who wanted to be an FBI agent, and had to pass Latin to get into law school (in those days the FBI wanted agents to have either a law or an accounting degree). I saw to it that J got his B in Latin, and he saw to it that people didn't bother me or sit at my table without my let or leave. I suppose that was a special case. ============= And now a rather important discussion: Evidence obtained under duress to be admissable in military court? Jerry, http://www.cnn.com/2008/CRIME/06/30/cole.charges/index.html Even if the citizens of our nation do not care, anyone in uniform needs to watch this case closely. If any evidence obtained under duress is admissible in court, it means that anyone under military jurisdiction can be removed from US soil, waterboarded until they admit guilt, and then returned to the US or a US operated base overseas for a military trial using the evidence obtained under duress. What standards will the judge hold the prosecution to? If the evidence is in fact inadmissible, will anyone be punished for waterboarding someone to obtain a confession that can't even be used? More relevant to serving military members, if ANY evidence obtained during an interrogation involving a waterboarding where the tapes were destroyed is deemed admissible, who would reasonably submit themselves to such a system? At this point, utilizing the globally recognized "right" to avoid being forced to provide self-incriminating statements may be followed by a lengthy flight in an unmarked bizjet and a trip to the dungeon for a little motivational experience. I’m sure at some point, those behind the Inquisition thought it was a fine idea, crucial to the survival of the nation as it existed at the time. What better way to get the info the state needs, than to extract it under duress and then hold a trial using the extracted information, with capital punishment is a reasonable outcome? Waterboarding is not torture, but information obtained during interrogation under duress of any sort should never be admissible, and those attempting to gain evidence in this way for use in a trial that could lead to a death sentence need to be tossed in jail for human rights abuses. And yes I realize that the UCMJ allows extremely harsh penalties when dealing with battlefield offenses in the face of the enemy... After so many years however, I see no immediacy in this trial requiring the expediency of a battlefield courts-martial. Name withheld… Evidence obtained under duress and torture is a special case; but the general case of illegally obtained evidence is far less clear. The modern interpretation is that illegally obtained evidence -- obtained without warrants, or through illegal break-ins -- must not be admitted in court, as a matter of constitutional law. That is quite recent. The English practice is, or was when I was teaching Constitutional Law, to allow the evidence to go to the jury, but also to allow the jury to know how it was obtained; the jury could then estimate its relevance and veracity. This was the case for a hundred years in United States federal courts, and so far as I can tell, just about all the state courts as well. Then the Chief Justice of the US, under his authority as the presiding judge of the federal system, exercised his supervisory authority to forbid use of illegally obtained evidence in federal suits. His reasoning was that federal agents had abused their authority, and this was a good means for requiring them to pay attention to rules. For a long time that rule prevailed, and over time some of the states -- about half -- adopted it explicitly to apply in state cases. The other half of the states continued to adhere to the rule that the evidence went to the jury but so did the story of how it was obtained. "We beat it out of him" usually got the jury's attention, and if that "confession" was the only evidence, than the usual verdict was acquittal. However, if the illegally obtained evidence -- including coerced confessions -- contained critical evidence, such as the location of a dead and mutilated child's body, juries would generally acquit, sometimes with a recommendation that the officers in question be charged. During the big liberal court "reforms" when the US Supreme Court discovered fresh new rights that had been overlooked for two hundred years, it was decided that the rule -- and up to then it had only been a rule, and applied only to federal courts unless a state had explicitly adopted the rule -- was a constitutional right, and applied to all the states, both those which previously adhered to it and those which had explicitly rejected it. The argument for the rule is that the executive department will behave itself if it does no good to get confessions through the third degree or illegal searches; the argument against it is that a criminal -- a murderer, or other infamous criminal -- should not get king's X "because the constable blundered." These matters were debated in state legislatures, and as I said, up until the US Supreme Court discovered an emanation from a penumbra in the Constitution made the exclusion rule a constitutional right, about half the states had adopted the rule and about half had rejected it. We come now to coerced confessions. Clearly we don't like the idea, but is exclusion of evidence the best way to assure justice? My inclination is on the side of the expanded view of the Fifth Amendment, but I do point out that there have been others to disagree. Jeremy Bentham, hardly an advocate of tyranny, thought the rule absurd (see also this). Bentham said that the privilege of not having to give evidence harmful to oneself was absurd: the purpose of a trial was to discover truth, and the fact that it was hard on the accused to be required to testify was "the old woman's argument." There is considerably more on this subject, and the bottom line is, what are you trying to accomplish? ========== English legal system. Jerry, Judges. The system which selects judges in the UK is rather like the rules of cricket, perfectly obvious to those born here, just as a bird instinctively knows how to build a nest. For Americans and other lesser races born beyond the pail the system works like this; Judges are appointed by the Lord Chancellor, a working barrister as well as politician who still leads the prosecution in the most serious cases, and who is appointed by Queen on the advice of the Prime Minister. They are chosen from the body of senior barristers for their "soundness". The Lord Chancellor is restrained from making radical choices by, literally, his Peers. These are the other senior judges, the Lords of Appeal, who also sit in the Upper House. Were the Lord Chancellor to make too many bad decisions, the other senior judges would no longer take luncheon with him. Although the line is becoming blurred, in essence barristers only address the court, and solicitors do all other legal work including discovering such facts as the barrister will present on behalf of the prosecution or the accused. A High Court Judge has almost unlimited power whilst sitting and although this is exercised sparingly and with caution it can be, and has been, used with great effect in preventing injustices by over zealous prosecutors or litigants. For example when a detective made a contemporary note of the accused's confession during a short car ride but was unable to repeat this feat in twice the time in while sitting at a desk in the court, it was the detective and not the formerly accused who found himself facing charges. This system prevents lunacies like the Macdonald's hot coffee judgment at the expense of having a deeply conservative judiciary. On the whole it has served us well. John Edwards =========== Old News on Climate Change Dr. Pournelle -- In 1968 or 1969, long before the term "global warming" had entered the common lexicon, there was a published unclassified literature review commissioned by the CIA which looked at then current paleoclimate research -- ice, lake and ocean bottom cores, chiefly. I have tried to locate the report via online searches to no avail. (I remember the report from an article in either Current Science or My Weekly Reader in Mrs. Wiedeman's science class in elementary school.) The gist of the report's conclusions was that the Earth was then in an unusually consistent and clement climate period and that it was reasonable to assume that this would soon change to a period highly variable and inclement climate. The article stated that the CIA was interested in the climate because as goes the climate, so goes the weather and thence food production and political stability. I have continually been reminded of this little news story during all the discussion of anthropogenic global warming/climate change, especially with reports over the past few months about CIA and Pentagon analysts looking at climate change.

Thursday,
July 3, 2008 I Been Thinking Dr Pournelle 1. Misunderstanding Dr Erwin's position 2. Toward statism 3. Energy = Wealth 1. Misunderstanding Dr Erwin's position Pate's distaste for Dr Erwin may stem from his -- Pate's -- ignorance of the word expatriate. Pate twice referred to Dr Erwin as an 'ex-patriot'. http://www.jerrypournelle.com/mail/2008/Q2/mail525.html <Tuesday. July 1, 2008> I have never met Dr Erwin, but I have read his missives to Chaos Manor, and I never found any cause to question Dr Erwin's patriotism. The two words -- ex-patriot and expatriate -- sound alike. The definition of expatriate that I prefer is found in the American Heritage Dictionary: One who has taken up residence in a foreign country. ex = out of; patria = fatherland; that is, one who is out of his fatherland. (I apologize for the pedantics.) Pate may have used 'ex-patriot' as a slight or from ignorance. I choose to believe that it stems from ignorance. (I intend no insult. I am ignorant of many things. Ignorance is a curable condition. Arrogance is less so.) I choose to believe that Pate intended no offense. Myself? I admit that I do not chase every link Dr Erwin gives in his weekly perusal of Britain, but I follow some. I find the English experience that Dr Erwin relates to be instructive. My father coined a law: Experience is not just the best teacher; it is the only teacher. I added a corollary: It does not have to be your experience. +++++ 2. Toward statism The growth of gov't reminds me of "Macdonough's Song": Whether the State can loose and bind In Heaven as well as on Earth: If it be wiser to kill mankind Before or after the birth-- These are matters of high concern Where State-kept schoolmen are; But Holy State (we have lived to learn) Endeth in Holy War. I am certain that you recognize the author. What I mean to say by this quote is that we Americans are speeding headlong to civil war. +++++ 3. Energy = Wealth You said this before in different words: Cheap energy plus innovation = economic growth. http://www.jerrypournelle.com/archives/archivesview/view51.html <Friday, June 4, 1999) In light of the current religious fervor over global warming, I believe the public must be taught this equation: Energy = Wealth (Use yours if you prefer, but I have a reason for setting the equation this way.) I do not mean Wealth in terms of microwave ovens and cars and Gucci handbags, but those are serendipitous by-products. The Wealth I mean is the luxury of choices. With energy, we have choices. With those choices, we can solve problems. Problems like hunger (which is now predominantly caused by politics, not a lack of production), disease, communications, transportation, species extinction, and, yes, global warming (if it exists). With energy, we can live as we choose and be good stewards of our world. Without energy, we lack choices. Without energy, humankind becomes nothing more than a ubiquitous great ape, bound to the environment and absolutely dependent upon the vagaries of nature. Without energy, humankind falls from living well to surviving brutishly. Your neighbor Ed Begley is an example of the success of the equation. Mr Begley can live green because he had money to make his home energy independent. But the manufacture of the goods that made his independence possible required much energy. As cheap as that energy was, the retail cost of those goods was high. If humankind curtails its development of energy resources, no one will be able to afford to 'go green'. Pate's ignorance is a small matter and easy to correct -- if Pate is willing to correct it. But I doubt that Pate has any religious convictions about the use of 'ex-patriot', vice 'expatriate'. I fear the Egregious Greens are driven by religious fervor, and their ignorance is less amenable to correction. ('You have eyes but see not; you have ears but hear not.') I thank you for doing what you can to make the truth available to them. If they choose not to learn, the fault is not yours. Live long and prosper h lynn keith ================ Hi Jerry, Just a quick note: back when I taught a course in automated reasoning, which can use a lot of statistics, one of my favorite counter-intuitive examples was based on the effect of extracting confessions under duress. Under entirely reasonable assumptions, it turns out that the ability to extract a confession increases the likelihood that the subject is innocent! Practically speaking, this means that extracting evidence under duress is counterproductive to the goals of the prosecution. It is not only inhumane - and a violation of the principles that we ought to uphold - it is simply stupid. Cheers, Brad Certainly not a universal truth. If confessions contain information that only the perpetrator could know... One of Dr. Coles' examples was an illegal search for marijuana. A highway patrol stop aroused suspicions. The officer demanded that the trunk be opened. Inside was no marijuana, but a dead body. What is the constable to do under these circumstances? If the executive is entirely corrupt, and the people are more in danger from their own police than from criminals and terrorists, then drastic restraints may be needed -- but under those circumstances the restraints are not likely to work. If the Legions have taken control, then one may appeal to Caesar, but the judges hear Caesar better than they hear the pleas of their neighbors. The remedy in the English tradition has been the jury system: but in the US we tend to restrict what the defense can tell the jury, thus nullifying that safeguard. Of course given the imbecilic rules we have allowed the lawyers to impose on jury selection, and the Mickey Mouse trial rules that make simple trials last months (lots of billable hours! I was in court!) we may never be able to use a jury system to protect us from the Norman Invaders oops elected officials. My point is that fiddling with the rules of evidence is not usually motivated by a desire to make trials a means of discovering truth. Like our education system, which is now designed by and controlled by the Blob of educrats, our system of justice has pretty well fallen into the Iron Law trap. == The Value of Evidence Obtained by Torture See this paper, which analyses the question from a bayesian perspective: <http://ourworld.compuserve.com/homepages/rajm/interro.htm> One implication is that "terrorism cases appear to run a considerable risk of a reversal of the inequality given above, and thus to the counter-intuitive situation of a confession of guilt actually contributing to evidence of innocence." -- Harry Erwin, PhD, Senior Lecturer of Computing, University of Sunderland. Computational neuroscientist modeling bat bioacoustics and behavior. http://osiris.sunderland.ac.uk/~cs0her The use of confessions as confessions, as opposed to a source of information, is a different matter. Confessions obtained under duress are automatically suspect (at least to an intelligent jury); it is the corroborative evidence that is important here. Note I am hardly arguing in favor of rubber hoses in the back room of the police barracks. I am stating that there have been other views of this matter; and of course coerced confessions are the extreme end of the illegally obtained evidence rules. The Republic managed for near 200 years without a Constitutional right to exclusion of improperly obtained evidence. And what should have been done with that dead body found through an illegal search? == Re. Confessions & Selection of Judges A possibly interesting historical note: The judicial system of Ancient Israel (at least as far back as the early Talmudic era, probably since Biblical times) completely discounted confessions in criminal law. In reply to John Edwards: The English system for the appointment of Judges may work there yielding "a deeply conservative judiciary", but the same system, seeded with "activist" judges, can have the completely opposite result. I offer the modern Israeli High Court as an example. --Joel Salomon ============ -- Canada Satellite to hunt asteroids as well as high altitude satellites Jerry, an interesting blurb from the University of Calgary <http://www.ucalgary.ca/news/june2008/NEOSSat> "NEOSSat telescope June 26, 2008 Asteroid-hunting satellite a world first Canada's NEOSSat space telescope to discover near-Earth objects and track high-altitude satellites Canada is building the world's first space telescope designed to detect and track asteroids as well as satellites. Called NEOSSat (Near Earth Object Surveillance Satellite), this spacecraft will provide a significant improvement in surveillance of asteroids that pose a collision hazard with Earth and innovative technologies for tracking satellites in orbit high above our planet. Weighing in at a mere 65-kilograms, this dual-use $12-million mission builds upon Canada's expertise in compact "microsatellite" design. NEOSSat will be the size of a large suitcase....NEOSSat is expected to be launched into space in 2010. The two projects that will use NEOSSat are HEOSS (High Earth Orbit Space Surveillance) and the NESS (Near Earth Space Surveillance) asteroid search program...." ========= Jerry, I thought that you should see this From American Thinker: http://www.americanthinker.com/2008/06/why_shakir_cant_read.html Shakir and his family is surrounded by well meaning very expensive professionals concerned about their every need. These professionals will use just about any amount of the taxpayers money to help these people.

Friday,
July 3, 2008 Coal-Energy Coal has been established as a fossilized biomass. Environmentalist/Global warming fanatics object to our use of it because of the carbon dioxide that it releases into our atmosphere. I have a question for them, “Where did that carbon exist prior to being locked up in the coal reserves?” After much hemming and hawing the logical answer is that it was in the air and oceans. The use of coal then is returning earth to a previous CO2 levels. Now if they really want to capture that carbon there is a simple solution. After a strip-mine is depleted fill it with biomass and cover it back up with earth. Given sufficient geological time coal is a renewable energy source. While we are waiting for better batteries and fusion reactors, we can liquefy the coal and use our current infrastructure for delivery in either a diesel or gasoline formula. The technology already exist to accomplish this just ask the Germans and South Africans. Mark D. =========== Paris, 7600BC. --- Roland Dobbins Modern Paris became an important city because the two islands in the Seine allowed the construction of fortified bridges that could prevent the Vikings from rowing upstream to ravage central and even southern France. The Vikings used to use rivers like highways to appear in unexpected place. I make no doubt there are other good reasons for Paris to be a major city, but that was explicitly the reason for establishing castles in modern Paris. ========== Shakir is not unique. The Juvenile facilities and group homes are full of Shakirs. The problem is that the liberals feel sorry for Shakir or his parent(s) etc. But they don't feel sorry for the people he will abuse in his life. They are the vulnerable ones, the elderly, sick, weak, etc. They are innocents who just happen to be in his way and he will rob, assault, cheat, or kill them just because they are in his way. They don't get the sympathy until after Shakir has completed his criminal assaults upon them. They will get a few words in the newspaper in some rare cases, while Shakir will eventually cost the citizens of the country a new car every year as he is incarcerated. If he kills someone in California and is sentenced to death he will cost a large luxury car every year for a couple of decades as a death row inmate. And that is just because he can't read? Not really, but because he was born to parents who had no intention of raising a child who was going to be any better than they are. Make an Iron Law out of that. CBS ========== The Law of Unintended Consequences. Jerry, It is reported that The Adult Internet Market Research Company has found a twenty to thirty percent increase in the membership of some pornographic sites at what is usually a slow time for them. Not only does this increase mirror the sending out of the $600, ah stimulus, cheques, but when asked many of the new members cite the unbudgeted arrival of the cheque as the reason that they joined. Nevertheless, we must continue to be grateful that we are not getting all the government that we are paying for. John Edwards ===========
========== 'And to a person, he recalled, they apologized that new money was unlikely because making the deflection of asteroids a priority might backfire in reelection campaigns.' Politically correct awkwardness ('to a person', what rubbish) aside, this is a worthwhile summation of the problem: <http://dotearth.blogs.nytimes.com/2008/06/30/ - Roland Dobbins =============
