Andre Norton was 93. Obituaries are at: http://www.nytimes.com/2005/03/18/books/18norton.html? http://tinyurl.com/3o82m http://sfwa.org/news/anorton.htm =================================================================== TOPIC: Hush Your Mouth (comments by Mark R. Leeper) Some of you may have heard about the recent diplomatic gaffe with Sudan. It seems a government website mentioned a nuclear test that had been conducted in Sudan. The government of Sudan, not greatly happy with the United States as it is, wanted an explanation as to the details the nuclear test. In fact what the website meant to say was the nuclear test was in Sedan, in Nevada. http://news.bbc.co.uk/1/hi/world/africa/4338835.stm The National Security Agency, our cryptology intelligence organization, actually does have a program called the Middle Enlisted Career Cryptologic Advancement program. (You can look it up in your search engine.) I do hope they don't have any memos around on websites saying that many of their peoples are going into MECCA. [-mrl] =================================================================== TOPIC: The Voynich Manuscript (comments by Mark R. Leeper) In the April 2005 issue of THE MAGAZINE OF FANTASY AND SCIENCE FICTION is a short article by Bud Webster talking about a fairly unusual book called the CODEX SERAPHINIANUS by Luigi Serafini. The book, published in 1981 in several languages, though really in no language, is a humorous art book. It would appear to be some sort of medieval manuscript describing a grotesque version of our world, but the writing is in no script that is recognizable. In pages and pages of indecipherable script it seems to be describing the world, but a world that is a strange and surreal version of our own. There is weird botany with images of little people who are part machine. A chimerical horse is shown with a back half that looks like it came from a termite queen. With no hind legs it has a wheel instead. The cover chosen from the book by the publisher shows in sequential pictures a couple making love and transforming into an alligator that slinks off leaving the bed empty. All this is apparently described in a script of unknown or indecipherable language. This book is in itself interesting enough for an article here, but Webster beat me to it. One thing that Webster does not mention is that while CODEX SERAPHINIANUS is apparently intended humorously, it is not the only book like this. (I am going to beat Webster to publication about the Voynich Manuscript.) There really is a manuscript written probably in the latter part of the 15th century that is indecipherable and itself has some very bizarre illustrations. The book is called the Voynich Manuscript, after its modern re-discoverer Wilfrid M. Voynich. It was found in 1912 in the library of a Jesuit college near Rome. The strange book is filled with odd botanical and cosmological illustrations and images of human figures. The style is one an alchemist or herbalist might have used. At least on first inspection the text looks like it could be a real language, but nobody has ever been able to make any sense out of the text. A letter found with the manuscript said that it had been bought by Rudolph II in 1586 and in the next century at least two scholars were given the book to decipher. Their attempts met with failure and the book was simply stored away until it came to Voynich's attention in 1912. Voynich also tried to have somebody interpret the language of the book including cryptographers who examined the manuscript as possibly being in code or hiding it real message. There was no success. The Voynich Manuscript eventually made it way to the Beinecke Rare Book Library of Yale University. Voynich's discovery itself is maddeningly detailed and complex. What remains of the book is about 240 pages in vellum. The page numbering seems to suggest that there were more pages at one time that were removed. http://www.world-mysteries.com/sar_13.htm describes the book containing * unidentified plants; * what seems to be herbal recipes; * tiny naked women frolicking in bathtubs connected by intricate plumbing looking more like anatomical parts than hydraulic contraptions; * mysterious charts in which some have seem astronomical objects seen through a telescope, some live cells seen through a microscope; * charts into which you may see a strange calendar of zodiacal signs, populated by tiny naked people in rubbish bins. SCIENTIFIC AMERICAN published an article last year about efforts to verify what the manuscript really is (http://tinyurl.com/ysp8p). Writer Gordon Rugg reports the conclusion is that the book is a clever fake. This conclusion is based in part on a statistical analysis of the length of the words. How does the length of words tell you if the book is written in a real language or not? This is one for the television detective show NUMB3RS. There is a problem with writing random words that are supposed to look like natural language. If you were just writing strings of letters and you were trying to vary the length as randomly as possible, you could not help yourself avoid this or a similar problem without knowing it. The length of nonsense words you would generate would follow a bell-shaped curve. But natural human language that evolved from humans talking is not nearly so regular. Humans do not generate words randomly. The length of words found in the manuscript fall into a normal (binomial or Gaussian) distribution. A mathematician graphed the frequency of the lengths of words in the Voynich manuscript and the average length was about 5 or 6 letters with the distribution being that of the famous bell-shaped curve. That pattern would almost certainly not occur with a naturally-evolved human language. If one graphs the frequency of words in a language like English, the curve would be broader and asymmetric because English words do not come from a random process. There is a greater frequency of usage of long words than there is in the Voynich manuscript. Hence it certainly seems a hoaxer was varying the words more or less by chance and not in the way that a real human language would. This was not the only analysis used, but it gives the idea. The analysis is not totally conclusive, but it makes it seem very unlikely that there is any sense to the words as written. Even if the Voynich is a hoax, the book is still one of the most interesting books in the world.

(2) Round percentages to the nearest 5% (or maybe 10%) so you have a reasonable number of buckets. [That bothers me a little. The forecaster who says 23% every day and it rains 23% of the days can be shown to be exactly right in his prediction, even if he is not helpful. There should be some way to answer if the forecaster who gives varying predictions is exactly right or not. -mrl] (3) For each bucket of samples, figure out the percentage of days that it rained for days that the forecasted percentage falls into that bucket. (4) Now you have some predicted percentages and some actual percentages. Dust off the statistics book and compute the correlation between the two numbers. Now, a real statistician would know what to do about the varying number of samples that fall into each bucket. I've also read a non-technical article about grading weather forecasters. They have a scoring system something like taking your percentage of correct forecasts and subtracting the percentage that you could have got correct by simply predicting the most likely weather for your region. The weather forecaster for Death Valley cannot get much of score under that system, but you can't win Olympic(tm) figure skating no matter how good your single-axle jumps are. [But that goes against the terms of the problem. If the forecaster says 23% probability you can't tell whether he is varying from the likely or not based on whether it rains or not. A prediction of 23% cannot strictly speaking be verified. -mrl] (Olympic, Olympics, and the 5-ringed Olympic flag are trademarks of some organization. That organization has lawyers and knows how to use them. The use of this word to describe other events, athletic or not, is forbidden without permission. There is no confirmation that the government of Greece has been asked to rename a certain mountain.) And responding to Mark's comments above, Dan continues: Rounding to the nearest 5% is done so you don't need to wait years to get enough samples at the various percentages. You can round to the nearest 1% if you have enough samples, but I don't think that is what you're looking for either. If you allow your forecaster to predict probabilities on a continuous scale, then to use this method you would have to take the limit as the bucket size approaches zero. It's not obvious (to me at this time) that such a function is well behaved enough to have a limit. Even if it becomes obvious, it's at best a more precise way of stating the problem until the algorithm to take the limit is found. On further thinking: (1) Even in the case of the constant 23% chance of rain forecast, saying that it is exactly correct after it turns out to happen that way is incorrect. Suppose I take my 20 sided die and, I predict a 5% chance of rolling a 20 on each roll, then I start rolling. After 100 rolls, I get 4 20's. That does not demonstrate that my prediction was wrong. My prediction was for the "chance" of rolling a 20 on any single roll. It was not a prediction that 100 rolls would contain exactly 5 20s. P(5 20's in 100 rolls of a 20 sided die) = 0.05 ^ 5 * 0.95 ^ 95 * (100! / (5! * 95!)) = approximately 0.180 So even the most likely prediction has only an 18% chance of coming true. But closer to the 23% example: P(25 4's in 100 rolls of a 4 sided die) = 0.25 ^ 25 * 0.75 ^ 75 * (100! / (25! * 75!)) = approximately 0.0918 So the forecaster needs a lot of luck to get a perfect score. (2) A problem in my suggested approach: A high correlation between the predicted chance of rain and the percentage of times that those days turn out to have rain still does not indicate a correct prediction. For example, I predict 10% of rain on half of the days, 20% on the other half. On my 10% days it rains 20% of the time. On my 20% days it rains 30% of the time. I think that gets me a perfect correlation of 1.0, but not a perfect prediction of the chance of rain. But if I have a high correlation, the data would probably suggest a smooth and monotonic mapping function to adjust my predictions to get a high accuracy. [-dtc] =================================================================== TOPIC: Weather Forecasting (letter of comment by David Shallcross) On weather forecasting, David Shallcross also responds: I am not a statistician, and in particular do not have any training in non-parametric statistics, which I think is the relevant sub-field, but I have a few ideas. First, here is an idea which I think is not good enough. Given probabilities of rain for each day, we can compute the distribution of the total number of rainy days. We then observe the actual number of rainy days. If this is more than the expected number, we look up in our computed distribution the probability of having this many or more rainy days. If this is fewer than the expected number, we look up in the computed distribution the probability of having this many or fewer rainy days. If, in either case this probability is sufficiently small, we declare the predictions to have been bad. So far this has a serious flaw. We have lost any connection to the individual days, so we would accept predictions of 0% on rainy days and 100% on rainless days, if they came in equal numbers. With this quality measure, we might do best to predict a constant percentage, based on overall climate. My second idea is to sort the days by their predicted probabilities, and divide them into groups. Say, the first group contains the 10% of the days with the lowest predicted probabilities, the second group containing the second decile, and so forth. Now we can compute the probability distribution for total number of rainy days in each group, and compare with the observations for the group. Again, declare the predictions bad if the computed probabilities of weather as far from the predicted means as the observations are sufficiently small. Since we have several batched observations to compare against batched predictions we have to be careful about the meaning of "sufficiently small". Now we do reward forecasters when it rains less often on days with low predicted probabilities, and rains more often on days with high predicted probabilities. I just had a third idea, which is aesthetically pleasing but impractical. Given the predicted probabilities of rain for each of n days, compute the probabilities of each of the 2^n different outcomes. Sort these outcomes in order of decreasing probabilities. After observing the n days, look up the predicted probability of the observations, and add up the total probability of getting observations of that probability or lower. If this is sufficiently low, declare the predictions bad. [-ds] =================================================================== TOPIC: FLIGHT OF THE PHOENIX (letter of comment by Dan Cox) In response to Mark's review of FLIGHT OF THE PHOENIX (03/11/05), Dan Cox writes (and Mark comments): I saw the original and enjoyed it. [The original almost caused a small riot at UMass. The first time I saw it was on television at the UMass Student Union. There was a room full of people watching the same movie. About fifteen minutes before the end (it is a long, long movie) someone came around and announced they were closing now. It took him about a minute to decide that that Sunday night the Student Union would be closing a little late. -mrl] It included the classic aviation plot of engineers vs. pilots. [You should see the movie DAM BUSTERS. Although there they cooperate. -mrl] The same conflict was also featured in THE RIGHT STUFF, in a scene in which a scientist(*) says something like "The specimen will ride in this capsule . . ." One of the astronauts tells him it's "space man". The scientist then resumes his speech with "The specimen will ride in this capsule . . ." Through the conversation, the scientists accent is such that it's not clear if he meant to say "specimen" or "space man", or if he was deliberately mis-pronouncing it to annoy the astronauts. [That, by the way, was Scott Beach playing someone like Werner Von Braun. Beach was (is?) a popular radio personality in San Francisco. His program turned me on to old time radio back in the early 1970s. He has a very distinctive voice. It was Beach who was riding with a not yet famous George Lucas and told Lucas, "I think we just hit a wookie." Lucas was puzzled and asked Beach, "What's a wookie?" "I don't know. I just made the word up." True story. -mrl] (*) "Rocket scientists" are more like rocket engineers if you ask me. Some people might think of that as an insult. I disagree. If you substitute a space elevator for the airplane, you get a "Star Trek: Voyager" episode which appears to be a remake of the original movie. The story does not work as well in a Star Trek episode, since you know how it's got to end. [You pretty much do in the film also. -mrl] However, they did do a good job in choosing Neelix for the role of the "enigmatic passenger who suggests an unexpected plan for survival". Neelix was always written as being light on technical knowledge and not easy to take seriously. [Ribisi is very good in this role. I prefer the original but by a much more narrow margin than I would have expected. -mrl] ---- spoiler warning ---- The two key scenes in FLIGHT OF THE PHOENIX (in my memory) are the "what kind airplanes did you design?" scene, then the scene in which the pilot tries to start the engine near the end of the movie. In that scene, the pilot gets to tell the designer "I've trusted your expertise. Now you've got to trust my expertise." Without this scene the pilot would just be a fool who was wrong throughout the movie. [He still was pretty much. He is less center-stage in the remake, but you also are more sympathetic to him. -mrl] [-dtc] =================================================================== TOPIC: STEAMBOY (film review by Mark R. Leeper) CAPSULE: A total surprise, this refreshing and enjoyable alternate history anime film packs quite a lot of action and adventure in one film. Particularly for fans of Jules Verne this film is a solid pleasure. Rating: high +3 (-4 to +4) or 9/10 Where do I start? I like adventure films and STEAMBOY is not only the most action-packed anime adventure film can remember seeing, it may also be one of the most exciting adventure films of this decade. STEAMBOY is one of the rare adventure films that gave me the same kind of excitement I got with the 1977 STAR WARS. The director is Katsuhiro Otomo who directed one of the classics of anime (though one that did not impress me nearly as much), AKIRA. He wrote the original manga "Akira" and directed the film based on it. He repeated that feat with what is for me the much more enjoyable STEAMBOY, working on the twenty-million- dollar film a reported ten years. STEAMBOY is in a sub-genre sometimes called "steam-punk." That is it is science fiction set around the time that Jules Verne wrote about. So how would I compare it to Verne films? Being anime it can easily beat the amount of action of 20,000 LEAGUES UNDER THE SEA or JOURNEY TO THE CENTER OF THE EARTH, two films I much enjoy. Animation is much less restrictive than live action. The filmmaker is limited only by what the artist can visualize. This is an adventure that gives and gives some more and gives still more after that. And still it is just in the early stages. It is a film on the responsibility of science and of the scientist that discoveries not be misused. Japanese films have been examining that theme since GOJIRA in 1954 as well they have a right to. But in this film, set in 1866 the technology that is in danger of being misused is steam technology. In 1866, Ray Steam works in a steam plant in Manchester, England. He wants some connection to his esteemed forebears. It seems he is the son and grandson of great steam inventors though he may not yet have their talent. But Ray does not know even where his father and grandfather are or what they are doing. He fills a role as a functionary in a steam plant to try to live up to the family name. One day a mysterious sort of spherical valve is delivered to him at his home, addressed to him from his grandfather. The message is to give it to nobody. But almost immediately there are two men at his door explaining why they need to take this odd device. Ray realizes he must protect the sphere from them and the adventure is off and running. His prized device will take him to London where the Great Exhibition of 1866 is soon to take place. The strange ball valve has something to do with an immense machine being built right next the Great Exhibition. Somehow involved in all this is a girl Ray's age named Scarlett. His relationship with her is anything but steamy. She is a vain and imperious, but Ray may need her as an ally against The Foundation, the organization trying to steal his grandfather's sphere. Ray is involved in a war involving steam-powered suits, steam flying machines, and machines that dwarf people. The film is in Japanese with (very good) English subtitles and it seems odd to hear all these early Victorians speaking Japanese. Like the film SKY CAPTAIN AND THE WORLD OF TOMORROW this is a view of the future as it might have been as seen from a point in the past. STEAMBOY is a large-scale adventure film full of a sense of wonder at technology and also a discussion of nuclear weapons in allegory. And it is a lot more. I rate it a high +3 on the -4 to +4 scale or 9/10. [-mrl] =================================================================== TOPIC: ROBOTS (film review by Mark R. Leeper) CAPSULE: The same team that made ICE AGE tries again to succeed in the CGI-animation film. But ROBOTS lacks all the magic of ICE AGE. The film is entertaining but it is definitely second-rate as current animated features go. It has some good ideas, but overall it tanks. Rating: low +1 (-4 to +4) or 5/10 Warning: Minor spoilers follow. In the competition of computer-animated films there are two giants vying. Pixar pulled ahead when it made FINDING NEMO and Dreamworks responded with the much weaker film SHARK TALE. In third place is Fox Animation Studios. They made ANASTASIA, TITAN A.E., and (their best) ICE AGE. Their latest entry is ROBOTS, so it invites comparison to ICE AGE. Just about any measure makes it seem as if Fox Animation did not understand why their ICE AGE was so good. ROBOTS takes place in a world very much like our world today but one in which there are no humans and only robots. Robots have evolved to have a society a lot like modern-day America. We follow Rodney Copperbottom (voiced by Ewan McGregor) from the day of his birth until he is a young adult. He wants to be an inventor and a repairer of other robots following the role model he sees on television, the master inventor Bigweld (Mel Brooks). However, when he goes to the metropolis of Robot City to find his fortune he discovers Bigweld's corporation very much rules the world. And these world rulers are backing a policy that there will be no more spare parts and inexpensive repairs for robots. Instead the corporation will back only costly upgrades. The robots who do cannot afford the expensive upgrades are doomed. Disillusioned, Rodney discovers that CEO Ratchet (Greg Kinnear)-- urged on by his evil mother Madame Gasket (Jim Broadbent)--has actually forced Bigweld into an involuntary retirement. Can Rodney reverse this industrial machine? A script is by Lowell Ganz and Babaloo Mandel. That is usually good news. They are the authors of films like PARENTHOOD, CITY SLICKERS, A LEAGUE OF THEIR OWN, and EDTV. But somehow the animation medium seems to have thrown them. On the plus side the script has about four jokes a minute and some hit the mark, but they rely to a great extent on vulgarity and body humor. This film may entertain children, but it may not be what all parents want them to be watching. ICE AGE had almost no body humor. It takes the time to develop the characters so that we get to know and care for them. ROBOTS has a more frenetic pace but very flat characters. The artwork is intricate with a lot of ideas, like a sort of Rube Goldberg transport system, but much less growth of the characters. The Robin Williams jokes are a poor substitute for giving us people/robots the viewer really has affection for. Perhaps it should not make a difference, but the characters of ICE AGE are organic. They are soft and covered with fur. The characters of ROBOTS made of metal. They look like they would clank rather than have the soft feel of flesh. In ICE AGE the goal of the heroes was to save the life of a lost baby by returning him to his father. In this film the goal is defending the institution of cheap repairs over pricey upgrades. That is what poor robots can afford. But this theme is a trifle abstract for an animated film aimed primarily at children. In ICE AGE the conflict is resolved by the heroes catching up with the child's father and then bidding a reluctant farewell to the child they have come to love. Here the conflict is resolved in a giant fight in which by sheer force the good guys kick the living rivets out of the villains. Force is what triumphs and not human/robot values. ROBOTS is a film that is very industrial, but one with little light or magic. I rate it a low +1 on the -4 to +4 scale or 5/10. [-mrl] =================================================================== TOPIC: This Week's Reading (book comments by Evelyn C. Leeper) Daniel Myers's THE SECOND FAVORITE SON (ISBN 1-877-27044-X) is an alternate history based on the South winning the American Civil War (though it starts well before that, during the Revolutionary War). Though Myers was born in Chicago, he has lived abroad a lot, most recently in New Zealand. That may be why the extrapolation doesn't work: the resulting society seems just like what we had before the Civil Rights movement. I might accept that in a world that would have been very different with both a United States and a Confederate States of America there might be communists, WWI, and a Depression. However, Myers also has interstates (in our timeline conceived of by Eisenhower for military purposes), Toyotas, and California as being known for its gay population (as well as the word "gay" used in this way). (Without a civil rights movement, would there have been a gay rights movement? Also, white as a wedding dress color became common only when Queen Victoria wore it, so the comments about it during the Revolutionary War era are just plain wrong. I'm not sure why the author decided to make this an alternate history rather than a straight contemporary mystery, but that aspect does not work very well. A. J. Jacobs's THE KNOW-IT-ALL (ISBN 0-7432-5060-5) is the story of Jacobs's "quest" to read the Encyclopedia Britannica all the way through. In a sense, this is similar to Herman Gollob's ME & SHAKESPEARE (reviewed 02/11/05)--it is a combination of discussion of the topic and memoir of the author. Unfortunately, although one of the blurbs describes Jacobs as "self- deprecating," that is not the impression I got. Indeed, the title seemed to sum up his personality fairly well. While reading the Encyclopedia Britannica, he kept correcting people or inserting weird facts he had learned into conversations. This would be bad enough, but the problem is that he apparently did not comprehend what he read very well. And the publisher does not seem to have had a copy editor for this book, maybe because they figured that anyone who had just read the Encyclopedia Britannica would not need copy-editing. Wrong. The first major mistake is on pages 73-74, when Jacobs says, "[if] a stranger says he was born any day between October 4 and October 15, 1582, he's lying. Why? Because there were no such dates. That's when the world switched to the Gregorian calendar, and they skipped those ten days." That's just wrong. "The world" did not switch to the Gregorian calendar, only the Catholic countries did so. Britain did not switch until September 1752; Russia did not switch until after the Revolution in 1918. (See my long discussion of this in my review of Mary Gentle's 1610 in the 02/20/04 issue.) Then on page 104, Jacobs refers to "M. Night Shamalan" (it should be "Shyamalan"), and on page 120, to "Finnegan's Wake" (it should be "Finnegans Wake"--no apostrophe). Ironically, on page 127, he says, "I make mistakes rarely--maybe once every four hundred pages"! Given all this, plus Jacobs' tendency to gratuitously insult various pop figures, I found myself thinking that my time could have been better spent reading the Encyclopedia Britannica. Oliver Sacks's THE MAN WHO MISTOOK HIS WIFE FOR A HAT (ISBN 0-684-85394-9) is a collection of essays about various peculiar neurological syndromes. The title essay is about a patient with the inability to interpret visual images: show him a rose and he cannot identify it as a rose, but let him smell it and he has no problem. "The Lost Mariner" is about a man with retrograde amnesia (a.k.a. Korsakov's syndrome). I can't remember if it used the term, but that is what the film MEMENTO is about. I would be surprised if the writer of that was not at least partially inspired by Sacks. And this is not the only pop culture derivative of Sacks's work. Just a few weeks ago, the "B" story on "House, M.D." was almost precisely the case described in "Cupid's Disease". (And the writers of "Medical Investigation" seemed to have taken their pilot episode from Berton Roueche's "Eleven Blue Men". This seems to be the season for taking television plots from classic medical case histories.) Michael Nyman has even written an opera based on Sacks's title essay. At times the writing is a bit dense, but still readable. (Roueche, mentioned earlier, wrote for a wider audience and is somewhat easier to read. Paul de Kruif, with his MICROBE HUNTERS and MEN AGAINST DEATH, predates both of them in this genre.) The consensus among our book discussion group, however, was that the descriptions of the cases were far more interesting than Sacks's philosophizing about them. [-ecl] [Actually the victims in MEMENTO and the Sacks book have different types of amnesia. The victim that Sacks writes about has amnesia that is both anterograde and retrograde. Those words sound fancy, but it just refers to whether the person forgetting things that occurred before or after the onset of the amnesia. In MEMENTO Leonard Shelby has anterograde amnesia. He remembers things before his injury but nothing for long after. Sacks's patient made it to the 1980s without problems, then suddenly started forgetting things both before and after the onset. He thought he was back in 1945 and still remembered nothing after 1945. His amnesia went both forward with short-term memory loss and backward forgetting things of the past. Charles Rainier in James Hilton's RANDOM HARVEST has retrograde amnesia. He has lost his entire past. (Fear not. A second injury restores his memory which is a great literary device and I am told makes absolutely no sense medically. How many things do you know that break if you hit them once but repair themselves if you hit them a second time?) Incidentally, my review of MEMENTO recommended THE MAN WHO MISTOOK HIS WIFE FOR A HAT. -mrl] =================================================================== Mark Leeper mleeper@optonline.net A sound American is simply one who has put out of his mind all doubts and questionings, and who accepts instantly, and as incontrovertible gospel, the whole body of official doctrine of his day, whatever it may be and no matter how often it may change.
