Spinner strobing as a "Bird Strike Countermeasure"

Then why did you announce it to thousands of people on the Internet, where it
will be archived for decades?

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.

Peripheral vision is much more sensitive to flicker than central vision. Some
people will perceive an irritating flicker in a lamp or computer monitor each
time they turn away from it, and yet the flicker will disappear when they look
directly at it.

The perception is limited to the impression that the light is flickering; that
doesn't mean that they can count the individual flashes.

First, for any flicker the phosphor has to be defective ...

How can the phosphor be defective?

No, that's just a symptom of the electro shock therapy.

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.

So ........ posting on r.a.h. and flying airplanes decreases sexual
activity???

Only, Rich, if you hadn't been using part of your brain for those
other functions. As many here have characterized flying, "the most fun
you can have with your clothes on" (I might dispute that, but that's
another matter) so I suspect sex isn't far from real pilot's minds.
EVER! Well, maybe when they break out of a cloud and are see a
mountain coming at them at high speed they are distracted a little.

And Mr Dudley keeps his mind clear of distractions, as he mentioned
somewhere here, too. I think, on that subject, Mr Dudley, sailplane
drivers probably get closest to the emotions expressed in High Flight,
but can't speak from direct knowledge of that. Dudley, the Mr is a
sign of respect, by the way. There are a select few here I'd demand
call me by my first name: "Professor".

Ponder (for the length your short attention span permits) just what
you typed above and parse it with your 100% error rate posting to the
net..

More information to which you're not entitled.

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

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.



Sounds good - he's walking plenty south these days, with large compass
turning errors . . .

Tina .........

Looking at the use ratio from a male standpoint, my wife maintains that I do
not, nor have I ever, used my brain before, during or after sexual activity.
Only since I turned 65 has she said, "It's all in my head". Conclusion: In
my case I can post and fly all I want.
