Hi, today we have a video about illusion. All we see around us are reflection of light which come to our eye and then interprets by our brain. So that it means that the bran is the place where the image of the things shapes. And that is the mind which make us able to see and eyes are just tools for this and they cannot make images by their own they just receive light and the brain interpret them. Here the brain interpret base on comparing and for interpreting it uses some method which are not perfect so that we sometime see something while in he real they are not that way.
