So, which way is the naked lady spinning?

I called it up and saw her rotating CCW for about a minute even after
bleinking and looking around the room and then back at the pic she
was still CCW.

Then I looked up and book marked the page and and then sent a link
to my wife and when I looked back she was CW. And just now I popped
back over and she is still CW.




HaHa!

I can make her do the "Twist", but it makes my eyes hurt...

So can my wife and while I love her dearly she does not have a 160 IQ and
she would be the first to admit it. Hell, she married me that pretty much
will keep her out of Mensa alone.

Bull****. You are hear to argue about aviation discussions and I
understand completly why you do it. It is because you have some
psycological need to argue and if you did it the way you do here you
would get your ass beat.

So whats that make you?

No, bad typist who counts on spell check to catch stuff and I tend to forget
that unless I hit the spell check button it doesn't work on this program.

Nope. The prop appears stationary and you see only the two.

What you see is the complete image (frame), not a composite of 4
'frames'.

You are both incorrect.

Then why are you making categorical statements about me?

I'm so impressed.

Why? Anyone can look up the specs, even though many people are too lazy to do
so.

There's a well-known phenomenon that can incapacitate pilots. A
propeller spinning so that it cuts through the sun's glare and causes
a stroboscopic effect on the pilot's eyes can result in confusion. A
frequency of less than between 25 and 55 Hz, depending on the
individual, can cause dizziness or nausea. It's called "flicker
vertigo" and the fact that it happens tells me that the human eyeball
(or at least the visual cortex) does have a frequency function of some
sort. 25 Hz on a two-blade prop would be 750 RPM and 55 would be 1650.
Some tests have found that frequencies as low as four to 20 Hz will
induce it rapidly.

It is probably more a consequence of intermittent photic stimulation, the same
phenomenon that can trigger seizures in susceptible individuals. As I recall,
the bulk of the response is outside the visual cortex.

Looks to me more like a detail issue, with the resolution
that diminishes with distance causing the illusion.

Each image actually contains two images, one that is simply blurred, and one
that is a line image with heavy unsharp masking. At close range, the fine
lines of the unsharp-masked image are visible, and the image built that way is
more prominent. At a distance, the adjacent bright and dark of the
unsharp-masked lines blends into a constant gray, and the contours of the
blurred image become more prominent.

His "cr@p" is one message, the flood of replies is what ruins "a perfectly
good forum"...

Killfiling or simply learning to ignore, I suppose is too much to ask...

"Mx" might as well be Zoom or Fetters, since he's proven apt at jerking
y'alls chain here...

Who cares? You posted this statement: "I'm only here to discuss
aviation."

Why are you discussing yourself instead of aviation? Why do you
lie so much?

The ONLY thing that will get rid of him is totally ignoring him.

Kill file him, and chide everyone else to do the same.
