    Incredibly,you don't need light to see. Like,a black hole can only be observed by matter going toward it and noticed by the X-rays the matter emits,but if you look at a black hole,you could see it. If you really need light to see,you shouldn't be able to see black. Ever thought of that? No. You only thought about keeping your sciency stuff to keep what you think is the truth.

    At 7:45, with that logic I would guess having that as a lens would reduce the size of our field of view to the same size as our retina?

    Wow. I just learned something. I never really got that about pin holes. But i used to think you could see inside a whole room through a key hole if you had a bunch of cameras on a grid and that is exactly the same darn thing i just never realized it. Wow.

  • aaron burnett
    aaron burnett 9 days ago

    So light goes through the pin ho!e, yes perfect. So once it's through how does it maintain its new adopted pin hole properties? How does the light remain a stream once it goes through the pin hole?

  • Gogo 31
    Gogo 31 12 days ago

    Well actually, the parallel between the eye and the retina+pin hole in a plane is inaccurate because if only one light ray per point is able to get through the pin hole, then the diffraction effect takes place so you won't see anything

  • Benjamin Anderson
    Benjamin Anderson 14 days ago

    The eye really isn't a pinhole camera though, right? It uses a lens. The iris is just there to control the amount of light, like on a real camera. So isn't it disingenuous to say "this is really how your eye works?"

    Could you use selenite to make a small screen that is far away appear...close or big? That would be nifty.

    Perspective projection vs Orthographic projection. Modern 3d graphics technology makes it easy to see exactly what the world would look like if your eyes were orthographic!

    If u dont get shrinkage as object moves away, wouldnt the retina need to be size of the object to see the entire object, else when I watch this cellphone, I could only see the part of the phone exactly the size of my eye (technically retina) exactly at right angles to my eye?

  • Adrian Empen

    I'm pretty sure this is NOT how our eyes work. Yes, our eyes are using a pinhole, which is our pupils, but it's purpose is to regulate how much light can enter our eye in order for us to be able to see in the dark and in daylight.
    What actually takes care of the sharp picture is the lense BEHIND the pupils. How the lense works is even more interesting and I encuorage anybody who is interested in how our eyes really work, to look it up, even here on youtube.

    Hey Michael, if your brain turns images from your retina upside down, what if some brains don't and those ppl live in an upside down world? They'd learn, through trial and error, as they grew up, to point at the vertically opposite direction when asked to point at something. And you couldn't undo it.
    Just like how the qualia that ppl don't know if the color they see is the color everyone else Sees.
