Why do mirrors reflect left and right but not up and down?

>>	Anonymous Thu Mar 21 21:01:58 2013 No.5628720 You're thinking about it the wrong way, instead of thinking the mirror reflects it left to right imagine that it flips you inside out ... Does that make sense? http://www.youtube.com/watch?v=msN87y-iEx0

>>	Anonymous Thu Mar 21 21:22:29 2013 No.5628757 Top of image shows top of object. Bottom of image shows bottom of object. Left of image shows left of object. Right of image shows right of object. Seems to work the same, bro.

>>	Anonymous Thu Mar 21 21:29:44 2013 No.5628766 In a mirror the image is switched front to back, not left right. That's why your mirror image still points right when you do.

>>	Anonymous Thu Mar 21 21:44:17 2013 No.5628783 >>5628778 because of the fact he was posting just to say "sage" that's not the point of sage

>>	Anonymous Thu Mar 21 21:45:29 2013 No.5628785 Someone has read the Feynman books... Also, if serious, mirrors don't "invert" reflections or something. They are a direct trace of every point of the object they can "see" to a surface, if this makes any sense.

>>	Anonymous Thu Mar 21 22:38:00 2013 No.5628881 >>5628757 But what you are calling the "left of image" is actually the right, from the perspective of the mirror.

>>	Anonymous Fri Mar 22 07:47:59 2013 No.5629654 Because a mirror is vertically inspired
