Ethel the Blog
Observations (and occasional brash opining) on science, computers, books, music and other shiny things that catch my mind's eye. There's a home page with ostensibly more permanent stuff. This is intended to be more functional than decorative. I neither intend nor want to surf on the bleeding edge, keep it real, redefine journalism or attract nyphomaniacal groupies (well, maybe a wee bit of the latter). The occasional cheap laugh, raised eyebrow or provocation of interest are all I'll plead guilty to in the matter of intent. Bene qui latuit bene vixit.

The usual copyright stuff applies, but I probably won't get enraged until I find a clone site with absolutely no attribution (which, by the way, has happened twice with some of my other stuff). Finally, if anyone's offended by anything on this site then please do notify me immediately. I like to keep track of those times when I get something right.

THAT'S HEDLEY, NOT HEDY!
In addition to being featured in many films of the 30s and 40s and providing Mel Brooks with a chuckle or two in "Blazing Saddles", the
late Hedy Lamarr (along with her husband) received what is considered to be the first patent dealing with spread spectrum technology in 1942. It was patent number 2,292,387 for the Secret Communications System, and the story behind it is related in Spread Spectrum: How an Actress and a Musician Gave Birth to this Revolutionary Technology. This excerpt explains the genesis of her interest in such things:
Hedy was born in Vienna, Australia, between 1913 and 1915 with the full name Hedwig Eva Maria Kiesler. She started her movie career between the ages of 15 and 17 in the movie, "Geld auf der Strasse." She married six times in her life. It was in 1933 that Hedy married her first husband, a man by the name of Fritz Mandl. Fritz was one of Europe's largest armament manufacturers. "He developed a reputation for selling bombs, bullets and airplanes to Hitler and whoever else wanted to buy them" (Micro Times). However, Hedy did not approve of her husband's actions. Hedy described Fritz as being extremely possessive. He would use her as a show piece for his clients and the cream of Austrian Society. Fritz was so possessive that Hedy was kept by his side during business meetings. It was at these business meetings that Fritz and his researchers would discuss radio communication and torpedeo warfare. "At the time, research was indicating that radio waves were better than wire for controlling weapons such as torpedoes" (Micro Times). For example, it would be difficult to have a wire long enouph to connect the torpedeo to the launch station in order to control the manuvers of the torpedeo. Even though Hedy had no understanding of the military portion of these discussions, she had a mind capable of comprehending the technical portions.

After four years of marriage, Hedy had had enough and left her husband. It was in London that she met Louis B. Mayer of MGM, who arranged for her to come to America shortly before World War II. When she was in America she wanted to help the war effort. She did so by using her technical knowledge that she learned in her husband's business meetings to create a Secret Communications System. By attending these meetings, Hedy learned that torpedoes were controlled by radio signals. However, these signals could be jammed by the enemy, making the torpedo inoperative. To protect these signals, Hedy developed the idea of frequency hopping. As the name suggests, when a message is sent it does not travel across one frequency as usual but it jumps between frequencies. "The message would move so quickly across the radio waves that anyone tuning in to a particular frequency would only hear a blip, and would be unable to intercept the message"

The quotes in the excerpt are from the cover story "The Birth of Spread Spectrum" by Anna Couey in issue number 166 of the MicroTimes which, as far as I can tell, isn't available online.

STRANGE LIT
Another excerpt from the history classic 1066 And All That by W. C. Sellar and R. J. Yeatman. I damned near fell off the chair in the meditation room while reading this.
Chapter 4

Britain Conquered Again

The conversion of Britain was followed by a Wave of Danes, accompanied by their sisters or Sagas, and led by such memorable warriors as Harold Falsetooth and Magnus the Great, who, landing correctly in Thanet, overran the country from right to left, with fire. After this the Danes invented a law called the Danelaw, which easily proved that since there was nobody else left alive there, all the right-hand part of England belonged to them. The Danish Conquest was, however, undoubtedly a Good Thing, because although it made the Danes top nation for a time it was the cause of Alfred the Cake (and in any case they were beaten utterly in the end by Nelson).

By this time the Saxons had all become very old like the Britons before them and were called ealdormen; when they had been defeated in a battle by the Danes they used to sing little songs to themselves such as the memorable fragment discovered in the Bodleian Library at Oxford:

Old-Saxon Fragment

Syng a song of Saxons
In the Wapentake of Rye
Four and twenty eaoldormen
Too eaold to die ...

The Danes, on the other hand, wrote a very defiant kind of Epic poetry, e.g.:

Beoleopard
OR
The Witan's Whail

When Cnut Cyng the Witan wold enfeoff
Of infangthief and outfangthief
Wonderlich were they enwraged
And wordwar waged
Sware Cnut great scot and lot
Swinge wold ich this illbegoten lot.

Wroth was Cnut and wrothword spake.
Well wold he win at wopantake.
Fain would he brake frith and cracke heads
And than they shold worshippe his redes.

Swinged Cnut Cyng with swung sword
Howled Witane helle but hearkened his word
Murie sang Cnut Cyng Outfangthief is Damgudthyng.

RHETORICAL KNIFE FIGHT
The publication of Jeffrey Toobin's
A Vast Conspiracy : The Real Story of the Sex Scandal That Nearly Brought Down a President is initiating a full-scale, bombastic rhetorical assault from all parts of the political spectrum, and Gary Kamiya's review in Salon is certainly no exception. Some fun parts include:
... what remains [in regards to the things Clinton is supposed to have been guilty of] is "compromising financial entanglements." What, exactly, does this mean? What entanglements? The ones that two independent counsels and a Senate committee couldn't find? Apparently, it means that long ago the New York Times pronounced that Clinton was caught in "compromising financial entanglements" -- and once that judgment was rendered, the "legalistic" disposition of the actual case becomes moot. He may have slithered out of this one, but we all know he's guilty of something. Such reasoning does not sit well with paeans to the "rule of law."

"With an almost comic circularity of reasoning, the very existence of the inquiries about Whitewater were seen as proof that they were justified," Toobin writes. "The New York Times editorial page often spoke this way. 'Much as President Clinton might wish,' the editors wrote in a typical passage, '[Whitewater] ... just won't go away. It keeps popping up in Congressional inquiries and newspaper accounts.'" Toobin cites another, even more Orwellian pronouncement when, on "the eve of one of the many congressional hearings on Whitewater, the paper intoned, 'Mr. Clinton came to Washington promising to end the casual conflicts, favoritism and insider deals of the Reagan-Bush years. The very existence of these hearings attests that he has done little to honor that commitment.'"

Did any winners emerge from the Clinton crisis? Certainly not Clinton, whose most unattractive personality traits were revealed for all to see. Nor did the players in the "vast right-wing conspiracy" fare better. The higher-minded of the "elves" no doubt liked to imagine themselves as fearless fighters for justice, but they were exposed as tawdry dirty tricksters, Machiavellians out to destroy their enemies by any possible means. In the age of Gingrich, Limbaugh and the Christian right, this version of "conservatism" has attempted to swagger its way into acceptance as a legitimate right-wing stance -- but it is a cold-blooded, absolutist, instrumental morality that has much more in common with the ends-justify-the-means approach of the Stalinist left than with true conservatism, which is based on measure, decency and other intangible virtues.

And this all could have been prevented had everyone internalized the teachings of proper moral avatars like, say, George Roche. Although I should gently castigate Salon for lagging my piece about Roche by over three weeks, their use of someone who actually attended Roche's school provides enough fun, new material to more than make up for their belatedness.

A "KINDLER, GENTLER" PROTEST
James Henderson of the American Center for Law and Justice claims that
Colorado's 1993 "bubble" law tramples on his right to free speech. According to Henderson, who's representing the anti-abortion forces in front of the Supreme Court, the law that requires anti-abortion protestors to remain at least 8 feet away from patients entering health-care clinics that perform abortions restricts his "gentle and compassionate way of sidewalk counseling. Colorado's way is to put me so far away I have to scream and yell." Uh huh. Think for a minute when, if ever, you've found yourself screaming and yelling at someone from eight feet away. Then think whether you were screaming because the huge, three-stride gap between you prevented them from hearing other than words hollered at hog-calling contest decibels, or because the message you were attempting to convey was not exactly "gentle and compassionate."

The best argument I've seen against this ridiculous contention was offered by one of the Supreme Court justices the last time they heard this case (in 1997 when they returned to case to the Colorado state courts to reconsider it in light of the Supreme's decision in a related New York case). A justice noted that the attorney arguing that an 8 foot bubble didn't allow reasonable conversation to take place was himself at least 20 feet away. He then asked if the attorney felt that he couldn't reasonably present his case unless he were within 8 feet of the justices.

It's not uncommon in this country for stalkers to get restraining orders ordering them to keep 50 or even 100 feet away from their prey, even if they've not yet even touched them. The point is to restrain them from following through on verbal threats. In light of that legal precedent it is not at all unreasonable to maintain an 8 foot barrier between women attempting to enter health clinics (and I've seen those who weren't obtaining abortions get the same abuse as those who were) and those whose movement has verbally and physically assaulted women, vandalized health clinics even to the point of bombing them, tracked doctors to their homes which they've also vandalized (even killing their pets) and, of course, the pride and joy of the anti-abortion movement: the assassination of doctors to preserve the sanctity of life (not to mention the web sites and flyers presented in a "wanted: dead or alive" format that's sure as hell not intended to discourage further such acts). While the 8 foot bubble won't stop gunfire, it will certainly stop the physical intimidation of women and will in no way hinder the rational exchange of information between willing conversants.

Unless the entire anti-abortion movement is a pack of Seinfeldian "close-talkers" that has some sort of neurotic need to get within inches of others when they talk (in which case they need to see a psychiatrist rather than a lawyer), this entire lawsuit is a specious attempt to regain the weapon of physical intimidation for the anti-abortion movement. If you're still unconvinced then perform an empirical experiment. For the next couple of days keep track of how far away you are from those with whom you're having normal, everyday informative (or even not) conversations. And then figure out how many of those times you've needed to be screaming in their face to make a point.

TELEMARKETERS
Looka!'s a bit peeved about getting unwanted phone calls from telemarketers. I had the problem solved for a few years when I had my home computer hooked up to a modem directly connected to a line at my office. It was connected 24 hours a day, with phone calls only able to get through when one or the other side was disconnected via a power outage or some other problem. Sure, it also peeved those who wanted to get in touch with me at home, but I was still available (via another line) at my office to those who really wanted to attempt a conversation with someone notorious for disliking telephones. Also, everyone I cared to hear from had email connections, and I'm always available that way.

This worked fine until I obtained a cable modem, which made the phone line free for annoying incoming calls. I thought about it for a while and, remembering a friend's answering machine having the simple message "This is XXX-XXXX", went out and purchased an answering machine. I experimented for a while and arrived at a workable message: "You have reached XXX-XXXX. I screen all my calls, so if you're trying to sell me something crawl back under your rock. Otherwise, leave a message and I'll either return your call or pick up." It's worked like a charm, and it even seems like (although I haven't any numbers to back it up) the phone's ringing less often. Perhaps I've made some telemarketing "don't even try this asshole" list. And anyone who really wants to talk to me will wait out the message. It's a good compromise between ripping out the phone cord and letting every idiot with a phone and a warehouse full of widgets or a really special insurance plan annoy me at their convenience.

And just recently I made another technological leap when I found a good cordless phone marked down to less than half-price at the local huge Biz-Mart Warehouse thingie. So now when family members drone on and on (while I nod and say "yep" at regular intervals) and mother nature taps me on the shoulder, I can quietly sneak into the reading room rather than have to interject a "shut up I've gotta go!" into the monologue. The ensuing rude noises might even cause them to hang up anyway, so we're talking win-win here.

ONE OUT OF THREE AIN'T BAD
An interesting item from the Jan. 18
Social Studies column in the Toronto Globe and Mail:
Police in Sydney will get special powers to deal with the indigent during the Olympics. This worries Kevin O'Rourke of the New South Wales Council for Civil Liberties. He told the Sydney Morning Herald that such powers can be used "against the homeless, young people with their baseball caps on backward, ethnic and racial groups, and so on."
As much as it outrages me to see any state use strong-arm, thuggish tactics against the poorer elements of society, I can't help but see at least some good come out of this. If just one gen-x bonehead who thinks that wearing a baseball cap backwards is "weigh kewl" and on the bleeding edge gets smashed into the pavement by the Sydney donut patrol, it will be a good thing. While this annoying "fashion statement" might have made Mickey Rooney look really hip in those Andy Hardy films back in the 1940s, it lost its cutting edge cachet at least a decade before Jerry Garcia got his first buzz. Jack Kerouac has gone in and out of fashion at least three times since this was hip.

There should be a law stating that only baseball catchers should be allowed to wear a baseball cap in the backwards position, and even then only when they're crouched behind home plate fully decked out in their "tools of ignorance." All others caught with their baseball caps in the illegal position should be locked in a room containing only the complete "works" of Douglas Coupland and his groupies, a single Dee-Lite album on constant replay in the background, a couple of lava lamps for illumination, and a television showing the highlights of Bob Denver playing Maynard G. Krebs on "Dobie Gillis" on an endless loop.

We've still got time to wipe out this horrible plague upon mankind, but only if we act fast and brutally. The brief suspension of civil rights that will be required will be more than counterbalanced by the long-term increase in the quality of life. The aesthetic improvement of not having to see or hear skateboard riding "rebels" jabbering at each other in black slang that was stale back when the Sugarhill Gang first cut "Rapper's Delight" will almost alone be worth the cost in human lives, property damage and misery.

HISTORY LIT
Although Niccolo Machiavelli and Leonardo da Vinci were contemporary famous figures of the Italian Renaissance, they're never thought of as having crossed paths during that fascinating period. According to Roger D. Masters'
Fortune is a River: Leonardo da Vinci and Niccolo Machiavelli's Magnificent Dream to Change the Source of Florentine History , they not only met but collaborated on a plan to build a system of canals that would make the Arno River navigable from Florence to the sea. That this isn't well known can be attributed to several factors, the chief being the attempt and failure to realize a part of the plan under Machiavelli's supervision in 1504. With da Vinci not present during the attempt, the engineers in charge altered his plans and didn't dig the ditches deeply enough. The project was abandoned after a sudden flood destroyed a portion of the work.

Neither man wished his name to be associated with the failure of such a major undertaking for reasons having as much to do with self preservation as ego. It was a time of much political intrigue, and promising careers (and even lives) could be and sometimes were halted for lesser reasons. This has led to Masters constructing his tale on mostly indirect evidence, and while it might not hold up to a tag team assault by F. Lee Baily and Johnny Cochrane it seems reasonable to this reader.

Each man's reasons for participating in the project were true to their natures. Da Vinci wished to make Florence a seaport and thus further increase its tax revenues. He was also interested in taming the river that had inflicted three great and damaging floods in recent memory. This is in addition to his pure scientific interest in the flow of fluids. While Machiavelli certainly didn't disagree with increasing the wealth and safety of Florence, he mostly wanted to divert the flow of the Arno from Pisa, a rival against whom Florence had been at war for over decade. (It turned out that he defeated Pisa in 1509 without diverting the Arno, although his militia was beaten badly by the Spanish three years later.)

In addition to the story of the beginnings, development and ultimate failure of their plan, the book includes sufficient amounts of the history of the period to show the plan in the broader perspective of the intriguing politics of the time. There are also biographical sketches of both men as well as reproductions of quite a few of da Vinci's sketches related to the project. This is a well-written account of a failed project attempted by two of the greatest men living in one of the great periods of history.

CARTOGRAPHY LIT
The
Ambroziak Infinite Perspective Projection is a recently developed map projection that allows 3-D perspectives of terrain to be viewed with the help of 3-D glasses. The developers of this projection - Brian and Jeffrey Ambroziak - have written a book that makes extensive use of the projection. Infinite Perspectives: Two Thousand Years of Three-Dimensional Mapmaking presents a history of the art and science of representing topography with maps. It includes 80 color plates of many maps important to the historical development of the topic (e.g. maps of Imperial Roman highways and Leonardo's map of Tuscany), of which 20 use their new projection (which, by the way, is in use by both NASA and the Department of Defense). It's a pricey beastie though, with Amazon's 30% discount still leaving the price over $50.
