ELI5: Explain Like I'm 5

Persistence of Vision (film)

Okay, kiddo, let me explain something really cool called persistence of vision.

Have you ever seen a movie at the theater or on TV? Well, those moving pictures are created by a bunch of individual pictures called frames that are moving super fast.

Our eyes are able to see these frames even though they are moving really quickly because our brain is constantly processing what we see. Our brain takes all these different frames and puts them together in our head, making it seem like the pictures are moving like in a cartoon.

Even when the pictures stop moving, the image is still in our brain for a fraction of a second, which makes us think that the animation is still going on. This is called the persistence of vision.

It's kind of like when you spin a toy top really fast and when it slows down, it still looks like it's spinning for a little bit.

So, when you watch a movie, you're really just seeing a bunch of individual pictures moving super fast, and your brain makes it into a story that you can follow. Cute, right?
