The other day I was watching this really cool documentary on how our eyeballs and our brains work together to create this illusion of depth perception.
I used to think that it was because only because we had two eyeballs kind of like a 3-D movie where you put on these glasses and each eyeball see something slightly different than you put these two slightly different things together your brain and you see three dimensions.
It turns out that the whole lot of different strategies and programs that our brains use to create depth perception. Some of them don’t require to eyeballs so you can only have one eyeball still have good enough depth perception.
One of the ways our eyes deceive us is if you look at something like a mountain very far away and then you close your eyes and try to estimate the slope of the mountain by tilting your hand. Uou almost always overestimate the slope of mountain.
For some reason we maintain the height when you think about it but we compress the width. If you compress the width you will automatically overestimate the slope. Another illusion that happens is the further away something is the more we will underestimate the distance.
This is why some people drown. Because if you’re standing at the side of the lake and you look across to the other side you might estimate that is maybe a mile or less and so you start swimming. Then once you get a third of the way there you realize that it’s really like nine or 10 miles and this is why people drown. They underestimate the distance in this one so far out they don’t have enough energy to get back.
Got To Go Fishing
When he woke up one day he suddenly decided that he needed to go fishing. He didn’t know why. He just woke up and felt this compulsion to go fishing. He drove up to this lake that was about two hours from his house.
It was a big popular lake where you can rent boats, rent canoes, rent motor boats. He rented a motorboat and he was just aimlessly kind of puttering around until he found himself in this cove. There were no other boats or other people.
He was suddenly feeling very worried and nervous and scared like something terrible was about to happen. He looked across the lake and he saw a woman standing on the other shore. He thought that maybe she had got dropped off by another boat because she was waiting at the shore. He didn’t see any other boats.
He was about to go up to her to see if she needed any help when she started speaking to him. Even though she was about 100 yards away he heard her as if she was right behind him.
Something Is Hidden In Your Mind
She said I know there is something hidden in your mind. Inside the deep recesses of your memory is a box of pain. A box of fear. A box of anguish. You are purposely trying to ignore this, but you have to open this box up and embrace the pain that is inside.
Embrace the fear that is inside. Embrace the anguish that is inside because if you wait any longer the strength of this fear and pain and anguish will become too big to keep contained and it will over take your mind and you will go insane.
Her voice wasn’t scary or mean. It was more like a very very feminine very kind very angelic voice. When she finished talking he realized that his face was covered in tears.
Memories Come Flooding Back
Then he remembered what happened when he was very very young. He and his best friend and his parents and his best friend parents would come this cove every summer and have a barbecue would have a picnic and go swimming. One summer his best friend drowned.
His parents were freaked out. Both parents were freaked out. After about a week or two he started to forget that this happened. He started to create amnesia to keep this pain from overtaking him. A young child who sees his best friend drowned, his parents were both a mess. His parents and their parents were a mess. After about a month or two they stop talking about it.
They stopped talking to their friends. They started ignoring their friends. Pretty soon it was very easy for this young child to simply hallucinate everything away into the back of his mind. Because no one ever talked about the event because it was so painful.
He actually started to believe that it never happened. He started to believe that he never had a best friend when he was a child. All this came flooding back and he sat there in the lake in that boat for about two hours, weeping about what happened.
They say that the first thing that happened that led humans to evolve conscious thought was when animals first came out of the water to live on the land. If you live in the water you can only see a few feet in front of you. You don’t really have to think you just need to react by instincts.
Once the first creatures crawled out the water onto the land they could see a lot further away and this allowed the first space in the mind to evolve conscious thought to think about what to do if you can see a predator coming to think about how to catch the prey if you want to sneak up on it.
A couple of interesting ways the eyeballs create depth perception is the imagine both eyeballs being the base of a triangle and that what you are focusing on being the point of the top of the triangle based on the angles at the bottom of the triangle you can calculate the height of the trial which is of course the distance of the thing you’re focusing on.
This is one of the ways your eyeballs can understand depth. Another is how strong the muscles have to squeeze the eyeball to change the focal length of your individual lens inside your eyeball. Even with one eyeball you can kind of judge how far things are by how much your muscles squeeze.
Another very interesting idea about perception is if you look out into anything, a piece of paper at the world in a tree there’s only a very small portion of that vision were you actually perceive color. That’s the very center of your focus everything in your peripheral vision is perceived as black-and-white.
Brain As Hallucination Machine
Your mind has to hallucinate all of the color based on extrapolated data. It turns out that most of what we perceive is actually elucidated internally. Not only is there a lot of stuff out there that we can’t really see that we have to hallucinate there’s a lot of stuff inside our own minds that we can remember that we have to hallucinate in one way or the other.
