SciShow Tangents
Complexly
SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

Sight
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!SciShow Tangents is on YouTube!
