>You’ll need someone at home to swing a ruler wider than the hole behind the paper. If it swings by fast enough, you won’t be able to see it. But what’s the shortest time frame the eye can detect? To answer that, you’ll need to control the speed of the ruler.

as far as I know it's about 60 fps, this is also the reason why movies shot at 60 fps seem weird to us, because we're used to looking at movies as an illusion. 24 fps seems to be smooth and stuttery enough to make us feel comfortable watching movies. flies on the other hand have a sight of about 200 fps, that's why it's so hard to hit them: they basically see everything in slow-mo.

What?
Firstly, actual feed to the eyes is continuous. Secondly, our brains filter out several "frames" (several minutes each day of our mostly continuous vision) to improve our ability to use that data. I'm not sure what this phenomenon is called, though. Also, I've heard that so called "kinetic vision" is individuals who might be able to improve their own perceived FPS.
