Why Do Mirrors Flip Things Horizontally but Not Vertically? Here's the Physics

The (perhaps overly) charitable take on "It's not a paradox!" responses is that it's something which didn't appear impossible or weird to that responder, and the article failed to make the case for why there's even something that needs an explanation.

I'm curious to know what percentage of commenters who know exactly how mirrors work can perform simple tasks like assembling a puzzle with the same speed only looking through a mirror.

I don't think that would prove anything at all, since knowing how something works doesn't mean you can use it in place of your usual behaviour. You also have to unlearn manipualting things in non-mirror space.

Smarter Every Day actually has a video demonstrating a similar thing: https://www.youtube.com/watch?v=MFzDaBzBlL0

I know how a blindfold works and I can’t assemble a puzzle with a blindfold on. Is that curious?
