My hobby

includes thinking very deeply about things that other people couldn't care less about. Today I was sitting by the park I found. An older couple comes up to look at the falling water too. They have a stroller with a kid not more than 2. They moved to the upper area to see the water from above. As I looked at the kid, i wondered how he visually processed the moving water. This reminded me of the fact that newborns see everything upside down because the brain has not flipped the image that the eyes receive yet. This started a chain of thinking where I wondered if there were people whose images were not flipped. They would not know the difference from any other person. This would be because when directions, up and down, were taught, educators (teachers, parents or other) would say things like, look up to the sky. To a person who doesn't know what up is, it could be any direction. As long as it is consistent, up could mean anything.

I spent 10 or 15 minutes just trying to logically see an upside down image. It was hard but i got it. Then I thought about left and right. Would they be opposite as well? No. Because the image the eyes received is flipped, and not rotated 180 degrees. This means that left and right would be the same for everyone, whether their brain flips the image or not. Feeling satisfied with my thoughts, i left the park and went home.
