Episode description

Before you listen, just take a moment to think about how sight works: Light comes out of the sun, bounces off of a tree (or whatever), goes inside of your head, and hits some nerves which send signals to your brain which turns that into an image of a tree (or whatever)... I wouldn't believe it if I weren't looking at this screen and typing these words right now!

Also, what better medium to talk about seeing stuff than a podcast!
