Why we Have Blind Spots - and How To See Blood Vessels

YouTube Description:

I've made a lot of videos about juggling (and will continue to!) as well as minecraft. This is the first video I've made about a passion of mine that's larger than the other two combined - science! I hope to create videos which explain scientific phenomena at a well-researched middle level of detail.I am studying cognitive neuroscience at Brown University, and the trick in this video was shown to me by Professor David Sheinberg. A big thanks goes to him for all the awesome stuff he's taught me!

Perhaps because they live underwater and we don't. Plenty of animals have abilities that we do not. An eagle can see for miles around them. A shark can regenerate its teeth. Bats have sonar which helps them navigate in the dark. What separates us is that we are made in Gods image. Meaning, we are imbued with certain attributes which resemble Gods divine nature. For instance, man, like God, has an intelligence, a mind. We each have a personality as God does. We are creative beings, and use language. We are also moral beings. The initial perfection was a spiritual perfection, but since the fall we have been corrupted by sin. When we turn from our sins and repent, we are new creatures, and transformed into the image of Christ. This is how we are reconciled back to God, and how we attain again to the initial perfection of creation.

Genji, could you please do your befuddled believer baiting in posts more relevant to the... ahem... discussion... you're trying to initiate?

Interesting, I always thought the cells were arranged like the cephalopods since it's more logical.
Got to keep that in mind when I create my army of genetically engineered superhumans to take over the world.

Cool video. Knew about the blind spots, didn't know about the blood vessels casting a shadow.

Is this why I see blood vessels in my vision whenever I go to the optician and they shine a bright light in there, or is that something different?

GenjiKilpatricksays...

Sure. Could you post a "complete and utter bullshit/reassuring psychobabble" vid?

Psh, why you and gallowflak gotta hate on my lawlz like that?

It's more logical if you want them to be blind. The reason it is designed that way is because of UV light..water blocks it out, air doesn't..the blood vessels are in front to block out the UV light..otherwise you would be blind in a few days.

Since I'm an intelligent designer, I would just put a UV filter on the cornea, therefor solving this problem and increasing their ability to see in low light situations a little in one go.
