Spinner strobing as a "Bird Strike Countermeasure"
"cavelamb himself" wrote My girl friend's 15 year old daughter is like that. She needs LOTS of entertainment too. Nearly impossible to have a non-drama day. This seems to be more a part of the normal, for today's youth. Think of it, when you were young. If there was not anything on TV while you were at home, (good chance that there wasn't, with the selection of perhaps 5 channels if you lived near a big city) what did you do to pass the time? You probably entertained yourself. Things I did were to ride a bike around the neighborhood, dig another extension to my tunnels out in the woods, build a blanket fort (smaller years) read a book, tear something apart and put it back together again, (the last part was optional g) play with your toys, go roller skating, ....... and the list goes on. Now most things for the kids to do involve something or someone to entertain them, with possibly hundreds of TV channels, music videos, video games, internet (IM your friends) surf the internet, and so on. What do all or most of the things today involve? Something or someone to ENTERTAIN .....THEM! It also follows for teaching. We have to keep their attention by entertaining them, for them to even begin considering learning something. Not saying that this isn't true with your situation, since I don't know her, but that is somewhat a state of being for a 15 year old, especially the girls, I think. *Especially* the part about the drama! g -- Jim in NC |

In article ,
says... "Airbus" wrote in message ... In article , says... "Airbus" wrote in message .. . but generally Aspergers is considered less debilitating, less of an "illness" and more of a "trait". For personal reasons totally unrelated to aviation or the Eunuch, could you point me to a reference describing Aspergers as a trait rather than an illness? http://www.journals.cambridge.org/ac...e=online&aid=5 5139 Many Thanks. I've been having this discussion with my wife since my son was 'diagnosed'. It's one of those "spectrum" disorders, in which the degree makes all the difference. Many are high-level, high acheivers. . . In other cases, living with a family member can be a real challenge . . . |

"Mike Noel" wrote in message ... True, but aren't we talking about 40 cps when the prop RPM is 2400? Seems I have heard the 16 cps is all that is required for movies to appear continuous. I think the human eye loosed it around 12 or 13. However, we don't seen consciously either. Hence the reason an aircraft propeller will appear to be revolving slowly backwards at times. Visual perception is funny and complex. black & white films were 16 frames/second. Color films are 24 frames/second U.S. TV is 60 fields/second, European is 50/second. This is driven more by the need for phospors that 'decay' rapidly enough to not produce 'blurred' motion than perception issues. OTOH, A significant number of people can perceive 'flicker' in conventional- tube fluorescent lamps. which is at 120 flickers/second. I seriously doubt they can. I can discern the flicker in *some* fluorescent lights, but I can not discern 120 cps on a strobe. I think what they are seeing is the "sputter" of a cold lamp or a light that isn't starting correctly. The flicker I see in those lamps is considerably slower than 120 or even 60 cps. First, for any flicker the phosphor has to be defective which means the lamp is already defective so we can't expect it to be behaving normally. it would be interesting to see if those same people can discern even 60 cps in a strobe. Also, the eye -- and brain -- 'notices' things that are too fleeting for conscious identification. Google 'subliminal' advertizing -- IIRC, lab tests showed that injected imagery with a duration of only a few milliseconds had 'measurable' effects. It's controversial, but has been called one of the greatest myths of all time. It's generally accepted they are ineffective. http://www.sciam.com/article.cfm?art...E19&sc=I100322 According to the Scientific American article they at best distract the viewer. Roger (K8RI) |

Spinner strobing as a "Bird Strike Countermeasure"
There is quite a lot of evidence that repeated mental processes do in
fact modify the physical brain. Bagley's book "Train Your Mind, Change Your Brain", is worth glacing thru if you find the professional literature boring. If a person's mental activity is largely devoted to playing a simulator game and posting on the net, one can be sure other underused parts of the brain begin getting used to support those activiites. If you pilot an airplane often, the process becomes 'easier' because there's actually more brain devoted to it. Some other underused activity will be less supported. Researchers are always on the lookout for subjects who spend much of their time in unusual ways, so that their brain functions can be mapped with some of the newer imaging methodologies. Anthony, I have this infromed consent document here I'd like you to read. After you sign it we're going to stick your head in this fNMR brain bloodflow imaging device. . . . . Hey guys, don't laugh. It may sound funny, but we do that kind of stuff every day. And there are many many safeguards to protect all of our subjects, so don't start thinking after the process someone like Anthony after being subjected to intense magnetic fields will only walk north or something. although poorly On Dec 9, 5:48 am, Airbus wrote: In article , says... "Airbus" wrote There's something wrong with you - you know it, and you desperately need help. I heard something else in the last day or two that got me thinking. In addition to all of his other problems, I think I know what one of his largest problems is, that explain his behavior on the internet. He is addicted to attention. Positive, negative; it makes no difference. Attention is what he craves, and must have it, above anything else in his life. Just like drugs, he will get it, one way or the other. So there it is; another thing to add onto his list of problems. Addictive personality disorder. This one fits too well to not be true. Maybe - maybe not that simple. Attention craving, certainly, but addictive, not necessarily. I bet he doesn't play the lottery obsessively, or the horses. But I'll also bet he doesn't have an abundance of friends dropping in. It's more related to an inability to establish intimacy - something that went wrong in that department a long time ago - It will take a long time to get to the bottom of it, and a long time to get back out, but it is possible to work through it. . .- Hide quoted text - - Show quoted text - |
