Yes - I have a name writes:

My phonograph turns at either 33-1/3 or 45 RPM, which is just as relevant
to
this conversation as your mention of turbofans.


At any given moment there are thousands of aircraft powered by turbofans
in
flight.


Most phonograph records have been replaced by CDs

This is completely incorrect. Human vision produces no such artifact.
Anything moving beyond a certain speed is simply a blur; it never appears
to
move backwards.

No, motion pictures PRODUCE the phenomenon. It's an artifact of the
motion
picture, not human vision.

That is a function of shutter speed.

No, the human visual system will not do it at all.


Keep digging, you are half way to China already.


Except in this case he's absolutely right.

I'm sure I've seen wheels on cars that appear to be moving backwards. Are my
eyes defective?

Wrong, exactly backwards wrong. Rutger was correct.

I hadn't seen that in a long time. You need to update though to the

It replaces all of that with.

Shut the **** up, MX.
