  1. Re:Eyes on Thin CRTs to Challenge LCDs in 2005 · · Score: 1

    All perceived causation is simply highly likely correlation.

    It is an anecdote, which means that it is emprical evidence in support of a non-scientific hypothesis; that CRTs can cause eye damage. The qualitative part was the measure of the worsening of eyesight.

    As an anecdote, it is not intended to stand up to the rigors of scientific study. Without doing a controlled study, there is no way I could make the claim that CRTs actually do cause eye damage. However, I did not mean to phrase it as "my dog has fleas, so all dogs have fleas". I meant to say that "my dog has fleas, so at least some fleas attach themselves to some dogs".

    Several other posters have commented that it may have been the refresh rate of the CRTs that caused problems, and not the CRT technology itself. Indeed, there seems to be a plethora of anecdotes supporting that position. And it seems consistent with the data set I have gathered, so rest assured I will check the refresh rate of any monitor, CRT or otherwise, that I use from now on.

    So I hope we can clarify that I was not trying to prove causation, just that the correlation s tended to point in a particular direction based solely on anecdotal evidence and careful observation.

    The MiniGRAIL detector is a cryogenic 68 cm diameter spherical gravitational wave antenna made of CuAl(6%) alloy with a mass of 1400 Kg, a resonance frequency of 2.9 kHz and a bandwidth around 230 Hz, possibly higher. The quantum-limited strain sensitivity dL/L would be ~4x10-21. The antenna will operate at a temperature of 20 mK.

    -68cm CuAl sphere = ~2 1/4 foot metal sphere made of a copper/aluminum alloy that is 6% "parent" metal (the CuAl) and 94% filler metal.

    -Resonance frequency 2.9kHz = if you were to point a speaker at the sphere and output a soundwave of 2.9kHz, the sphere would have constructive wave interference and actually amplify the sound.
    -Bandwidth of 230Hz = not sure exactly how to explain this...
    -gravitational wave antenna = same as the radio antenna on your car: it (in theory, at least) picks up gravity waves so they can be measured
    -operate at a temperature of 20mK = only 20 1/1000th's of a degree above absolute zero

    I beg to differ. Spending many hours a day writing résumés in front of a (very high quality) CRT had a seriously detrimental effect on my mother's eyes. She went from having better-than-perfect vision to having to wear bifocals in a very short period of time. Every time she went to the doctor, he had to increase her prescription. As soon as I convinced her to spend the money on an LCD monitor, her vision immediately stopped worsening.

    And in case you think it might be related to age, my younger brother, a high school student, has also recently been prescribed glasses due to too many hours in front of a CRT. That finally convinced my father to have an LCD for each PC in the house, thankfully.

    Imagine a fish who dies and is fossilized. The scales show up as patterns in the fossil, right? In fact, depending on how it's preserved, sometimes you can cut through them and see a fairly accurate cross-section of the scales.

    Now imagine a woven rush basket that somehow becomes fossilized (not likely, but just go with it). Now looking at the fossil, you're going to see the rises and falls of the individual reeds as they transverse all the perpendicular reeds in the design, and you'll be able to see the remnants of the grain running across and down the design as well. That's the sort of thing the student was studying - the anklyosaurus had a similar structure, only on a much smaller scale.

    Fossilization doesn't turn something into a piece of amorphous rock - it preserves the topography (at least) of what was fossilized. So it's possible to examine not only the major features (skeletal structure, etc.) but also minor ones which were preserved. Some fossils, if preserved before flesh decay occurred (frozen instantly, caught in a tar pit, etc.) can even have the features of skin imprinted on the rock. That's how we know archeopteryx had feathers, for instance.

I've seen some of the supply-side economics models, and they seem rather compelling. And "nothing but a hoax" is a rather strong statement, logically speaking - are you sure you want to hang your entire argument on an absolute generalization?

    I've also seen numerous examples of Colbert's "laissez faire" economics in action, some first-hand. My father was a pilot for one of the richest men in the world. This man owned several aircraft, a feat made possible only by his enormous wealth. Now the people who built those aircraft, the people who maintained those aircraft, the people who scheduled those aircraft, the people who inspected those aircraft, the people who insured those aircraft, and the people who flew those aircraft, were all paid from this man's wealth. We're talking the financial well-being of more than 100 families (including mine) which were entirely dependent on this man's financial status. And that's just to maintain his flight abilities, not to mention the thousands upon thousands of others whose income was generated by doing other kinds of work for him!

Let's say, just for the sake of argument, that there are only 1,000 people who can afford to pay for the full-time services of 3,000 people.

    the only thing keeping us going is confidence in our economy

    The only thing that has kept the economy going since the eradication of the gold standard has been its constituents belief in it. (Or more abstractly, it could be argued, its belief in itself.)

    This is aided by the idea that the basic unit of the U.S. economy, the U.S. Dollar, is backed by the "full faith and trust of the government of the United States of America", whatever that means. (For one thing, it means that all Americans are insured for money in the bank for up to $100,000.)

    Remember too, that Alexander Hamilton was an enormous proponent of the government operating in a deficit - he felt, among other things, that the debt of a government to its people would incur some accountability (no pun intended) beyond Jefferson's espoused "natural law". One could argue that a government's responsibility to its people is flexible and changing ("...but some animals are more equal than others"), but owed money is owed money in any monetary society, which helps keep the government in check (again, no pun intended).

  11. Re:Ermm... on Proof That Nature Hates A Fraud · · Score: 1

    At first glance, I thought exactly the same thing. One of the advantages of martial arts training is its ability to compensate for things like size and weight. I've known girls who were half my weight that I wouldn't mess with.

    But as I was thinking about it, I realized that there were other things to be considered. One is speed, which I think should be included with s&w as a critical component. Also, martial arts is a compensation for lack of some or all of those three factors. This is what equalizes the physical differences between people when they're fighting.

    The parent poster is right, though, in thinking that this is much like boxing. Or perhaps, in a more limited context, martial arts competitions. There are rules in place to prevent unexpected or unorthodox maneouvers, and the combatants are (one hopes) roughly similar in skill level. And let me tell you, if two opponents are identical in any three of skill, size, weight, or speed, the fourth factor will cast the deciding vote in the victory*. If I'm told I'm going to fight a guy who's as skilled in karate, as fast, and as heavy as I am, but I have a choice whether he's 6'6" (2m) or 5'4" (1.63m), I am certainly going to choose the smaller guy, because I will have an obvious advantage.

    Tying this all back to the bees... The bees only know a couple of moves. They're like boxers in that they have a limited number of things they are capable of doing. Wasps can't learn tae kwon do or judo. (If they could, we'd all be in trouble.) And they have relatively similar skills with their limited abilities. So this means that speed, size, and weight are major components in their battles, and more often than not, the bigger guy is going to win.

    Now what would be really interesting would be to take a wasp who has legitimate leader markings from a colony of wasps bred to be much smaller than their normal cousins, and put him in a fight with a non-leader from a colony that's been modified to be bigger than normal. Or vice versa - take a runt from the big tribe, paint him as a leader, and let him loose on the smaller tribe. There may be more to this than markings...

    *There are other factors which can decide the outcome, such as determination or desperation, but they are not as quantifiable and are therefore harder to evaluate. They can compensate somewhat, but only to a point.

    I suppose I oversimplified when I said that the purpose of war was to kill people. I think a more accurate statement would be to say that the purpose of war is to subjugate people. In most circumstances, that means killing enough people to inspire the remainder to be docile and obedient.

    Now in many circumstances, killing the military element can be enough to subjugate the civilians, but not in all cases, especially in areas of the world where the civilian and military elements are not clearly defined. How do you define 'military'? Only those people who have enlisted as regulars in the armed forces? By that definition, there were an amazing number of "civilian" snipers in Viet Nam... and a great many "civilian" combatants in Afghanistan and Iraq as well. I wonder how many of those are counted in the figure quoted here?

    To make matters worse, what do you do with a combatant that hides among civilians? When a sniper takes up residence in a civilian hospital (the likes of which happens regularly), what is the opposing force to do? How many of its own military force is an opposing army to sacrifice before killing the civilians? Whose interests are they supposed to have in mind?

    What makes all this interesting is that the armed forces of the United States actually do put the civilian population ahead of its own safety to a large degree, something that is unprecedented in the history of warfare. The U.S. militaries go out of their way to target military targets and leave the civilians in relative safety. This is a change even from WWII, where relatively indiscriminate carpet bombing was the norm. And it's certainly in marked contrast to the tactics used by Al Qaeda in 2001. I don't think they got a single military target, did they?

    Now here's an interesting thing... according to The Iraq body count page, the reported number of Iraqi civilians killed post-Saddam in Iraq is just over 16,000. That a far cry from the 100,000 which was estimated for the New Scientist article. Does this mean that less than 1 in 5 civilian deaths is being reported? I think there are some screwy numbers being thrown around here.

    And lastly, it's been reported that during Saddam's reign, as many as 2 million people may have died as a result of his rule. So even using the most conservative estimates, we're talking a 20:1 ratio of Saddam's dead to post-Saddam dead. So far I'd say there's not even a comparison.

    Having said all that, I must say that I still don't think the invasion of Iraq was justified. But we're stuck with it now, so we have to make the best of it. And I can tell you, that life would be considerably more dangerous for 300+ million Americans if a power void the size of Iraq is left to the radical muslims to take over.
