Also, this is the reason why "home movies" were all shot at
16-18 frames/sec, and not 24 frames/sec... to keep the cost
of film/developing down.

Schornak
claims that he can "see 40 frames/sec" as still pictures. Obviously
this is crazy since billions of people are sitting in movie theatres
world wide watching 24 fps movies and can't see a single frame
of it as an individual picture.. silent films prove that they can't even
see single pictures at 16 frames/sec!

In 1966 Riedel in Germany discovered that (movie) Picture
Fusion Frequency (PFF) increases with age in children. In
fact the PFF of a 7 year old is 10 frames/sec, while the PFF
of a 15 year old is 15 frames/sec... an astounding 1/3 increase
in the basic speed of visual perception.
This was confirmed by Weidenhammer & Fischer (1985)
as being due to the fact that Picture Fusion is INTELLIGENCE
related! Hence the increase in PFF of children is due to the
well known fact that the intelligence of a growing child increases
linearly from 0-18 years of age (due simply to brain growth).

Thus, it turns out that moves DON'T work on the principle of
"persistence of vision", but in fact work because of the
"slowness" of the human brain. The human brain can only
process 15 bits/sec of information, and this is what causes
the PFF of the average person to be 15 frames/sec... and this
is why "movies work".... not because of "persistence of vision"..
there is no such thing as "persistence of vision"!

(see: http://www.v-weiss.de/lehrl-full.html
for a full explanation )

OK... Schornak has take issue with Riedel's findings... and even
claims to have made some gifanimations which show that the
average adult PFF is not 15 frames/sec. He cites for instance
the fact that all modern movies are shot at 24 frames/sec.

Well, guess what? A little research turns up the fact that the
ORIGINAL movies (called silent movies) were actually shot
at 16 frames/sec! Why? Because it was experimentally found
by the fledgling movie industry that this is the minimum frame
rate that will produce a seamles, fluid, real life motion. Naturally
they were trying to use the minimum amount of film and run at
the slowest speed possible... in other words 16 frames/sec *IS*
the actuall PFF of the average adult!

(see: http://www.mtsu.edu/~dsmitche/rim458/materials/Video.html )

Also, this is the reason why "home movies" were all shot at
16-18 frames/sec, and not 24 frames/sec... to keep the cost
of film/developing down.

So why are modern films shot at 24 frames/sec.... because of the
SOUND TRACK for chrissakes! It turns out that 16 frames/sec
is too slow to record sound... hence when "talkies" came into
vogue they had to bump up the frame rate from 16 to 24 frames/sec
to keep the sound from warbling! (see above URL)

So at any rate... Riedel claims that the PFF of the "average adult"
is 15 frames/sec. CLEARLY the entire history of the movie industry
CONFIRMS that fact!

Furthermore of course, Riedel claims that the PFF goes up with age
(in children) from 10 fps at age 7 to 15 fps at age 15. Well, now that
we have established the ACCURACY of Riedel's result for adults, I
don't think there is any reason to doubt his measurements on the
scores of school age children either... clearly we can trust his result...
at least his peers Weidenhammer & Fischer, and Seigfrieid Lehrl
(URL above) trust it and have also experimentally confirmed it.

So Schornak doesn't know what he's talking about... and his
"gifanimation experiments" are a bunch of baloney. Schornak
claims that he can "see 40 frames/sec" as still pictures. Obviously
this is crazy since billions of people are sitting in movie theatres
world wide watching 24 fps movies and can't see a single frame
of it as an individual picture.. silent films prove that they can't even
see single pictures at 16 frames/sec!


FINALLY, of course... as any trained scientist can see, the "PFF"
so called is nothing more than a direct measure of the Fourier
frequency spectrum of the motion being filmed. The PFF is the
Fourier CUTOFF FREQUENCY of the observers brain! What this
means is that 1/3 of the frequency spectrum seen by an adult is
INVISIBLE to a 7 year old child.... meaning that 1/3 of the everyday
motion seen by an adult is INVISIBLE to the 7 year old!

1/3 of the world that is visible to an adult,
is INVISIBLE to a 7 year old... and this is
entirely caused by the "brain growth deficit"
of the child compared to the adult!

THE SIGNIFICANCE of this, is the fact that the Secular Trend
in human growth shows that ALL ADULTS are as much as 20%
short of full growth.... ergo.... 20% of the natural world is
INVISIBLE to the average person....!

This INVISIBLE WORLD is none other than the so called
"Supernatural World" of Religion... it is in fact what is popularly
called HEAVEN..!

This then, constitutes an ELEMENTARY scientific proof of
Heaven... and hence GOD..!

For cripes sake..... isn't there ANYONE on these physics
newsgroups who is competent in elementary Science....!!!

Here I sit holding the world's first competent scientific proof of
God... and I can't even find anyone competent in elementary
Science to discuss it with for chrissakes!

but the flicker phenomenon would still occur. <<<<<<<

I have no opinion on the issue one way or the other, but would like to
contribute a bit of mechanical knowledge of how modern film projectors work
(based on experiential as well as technical knowledge from the field). The
reason for the flicker is because the bulbs that put light on the screen are
filled with compressed xenon gas. Being a noble gas, it takes a lot of
electricity to light up the bulb-4000 watts, in fact, for an average bulb.
The electrons jump from one segment of the filament to the other, creating
an arc. As the bulbs age, pits are formed in the filaments, which causes
the arc to jump from one area to another.

Up close, the effect it is not visible, but since the light throw is upwards
of 300+ feet in large auditoriums, the small movements are magnified
immensely just as the 35mm print is magnified to 70' diagonal.

So, if you see a picture that moves, flickers, or dims and brightens
noticeably, that means that the bulb is approaching the end of its useful
life and needs to be replaced.

Hope this adds a little something!

I would guess the implanting of subliminal advertising frames within a
movie has something to do with this. Was it tested on both children and
grown ups?

Also, could the
eye also be responsible for this effect. After a flash of light, we continue
to see the flash for awhile. I would guess that this could be interpreted as
a form of memory. Is it different for a child than it is for a grown up?
