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

I tried it. I kept adding things to the killfile that would make messages
and threads that he posted not show up. Then one morning I went to check the
group and while I was showing 50 something messages not a single one
displayed because they were all caught in the Kill Mx filter in one way or
another.

Why are you discussing yourself instead of aviation?

Because most recent posts in this thread--including yours--persist in
discussing me, instead of the topic at hand.

After thinking that over...
It gets worse. There will be multiple rpm that will show the effect
under strobe conditions. With a 2 blade prop it can be sychronizing
every 1/2 rev. 3-blade prop every 1/3 or 2/3 rev, etc. in addition to
synching on the harmonics.

It isn't that bad.

Synchronization only occurs on integral fractions and engine RPM is
usually 1000 and about 2700 RPM so the possibilities are limited.

For a 2 bladed prop:

7200/2= 3600 - 1800 RPM

7200/3= 2400 - 2400 RPM and 1200 RPM

7200/4= 1800 - 1800 RPM and 900 RPM

etc.

I leave it to someone else to show how many blades you see at each RPM.

Since the prop appears stationary, you would see all the blades.

Yes, but how many virtual blades will you see?

Simple example: You are illuminating a 2 bladed prop running at 1000 RPM
with a strobe light pulsing at 4000 pulses per minute.

In the time between pulses, the prop makes 1/4 of a turn.

The prop is therefor lite up every 1/4 turn and it appears as though
the prop has 4 blades.

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'.

I'm talking about eyeballs and strobed light here, there are no "images"
or "frames" involved.

What you see is a prop blade in whatever position it is in when
the light goes off.

If the light is going off every quarter turn, you see a particular
blade end in four different places each a quarter turn apart.

If the light is going off every sixth of a turn, you see a particular
blade end in six different places each a sixth of a turn apart.

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.

I read that but can't buy it. How could perception of a single moving image
even begin to suggest such a thing? Higher IQ numbers perhaps, but not that
high.

Did any of you golfers check out the link below on the Amazing Kyle
Lograsso. A one eyed 4 year old that has a swing that is the mirror image of
Tiger Wood, drives 172 yards, and has shot as low a 41 on 9 holes!
Incredible.

I saw that and all I could think of was, "Damn, if that is my kid I am going
to be so nice to him because he is going to one rich little son of a bitch."

The danger of that is that his blatant misconceptions could get somebody
killed if not challenged.

So, you lied. You aren't only here to discuss aviation. You obviously
can't simply ignore posts discussing yourself. You continue to lie.

Seek help, Anthony. You're seriously damaged, you lying hypocrite.
