Flies to avoid tapping with Keanu Reeves in the movie "The Matrix" to escape the bullet as a way out, are watching the time slowly passing. In the insects, mankind rolled up the newspaper in the air fast flying, but also like a thick syrup through the slow. Just as Rivies later walked sideways like a slow bullet, and flies had plenty of time to escape. The perception of time is different from ours, not just flies. The study found that for many different species, the perception of time is directly related to the size of the body. In general, the smaller the size, the faster the metabolic rate, the slower the time it flows. Studying the ability of various animals to detect the rapid flash of light provides evidence for this conclusion. The "critical flicker fusion frequency" (ie, the flicker frequency increases to the light becomes stable to the critical value) provides a time-aware concept. After this study and comparison of different animals, scientists revealed...
