Feynman and the mirror dilemma


Das Borgen

Recommended Posts

Position yourself in front of a mirror and you'll notice it immediately. The text on your sweatshirt is reversed. The part in your hair has switched to the other side of your reflection's head. The mole on your left ear stares back at you from your mirror image's right earlobe. Before you stands a bauplan reversed; what was once left is now right, and vice versa. And yet, up remains up and down is still down — as though the mirror knows to switch left and right, but not top and bottom.

This, of course, is not the case. The mirror doesn't "know" anything about your position; it simply reflects the light that hits it, doing so as objectively as any inanimate object knows how. So how does a mirror mix up left/right but not up/down?
