What is the history of the movie's 24 frames per second?

From Baidu know: in the earliest movies, a still image is called a "frame (Frame)", the film is 24 frames per second, why 24 frames, this number is how to come, because of the visual phenomenon of the human eye is exactly in line with the standard of 24 frames per second, so there is no point in using more than one will also be wasted movie film, increasing costs, so the 24 frames per second. It is 24 frames. This 24 frames per second is the commonly used format of movie film, that is to say, shoot a second of the movie, the film to go 24 frames, to put it bluntly, I want to camera to shoot 24 negatives Less, the human vision of the tentative is 0.01 seconds, the human feeling does not move. Because it is for people to see. More is useless. Similarly, for dogs to see at least about 50 frames per second. That's why dogs don't like watching TV as much as cats. Depending on the playback device, the concepts of field and frame rate are easy to deal with. There are two ways to display a frame, one line by line, two single frame, if the line by line is actually 24 frames, then 48.
