How is that not flipped vertically? — Agree-to-Disagree
Place the mirror flat on the floor like a rug — Agree-to-Disagree
It's... still not flipped vertically. — Lionino
How does putting the mirror on the floor not do exactly that (assuming x axis is vertical, usually it is y or z by convention).To flip something vertically means to draw a horizontal line in the center, and take everything in coordinate +1 and put it in -1, +2 to -2, and so on, now take -1 and put it in +1, -2 to +2, and so on. — Lionino
In other words, what we see in a mirror is an optical illusion? Does the brain try to make sense of the symmetry flip, by imagining the third dimension inverted? :joke:It doesn't flip things vertically or horizontally but in the third dimension - front to back. The confusion arises because humans have bilateral symmetry. — unenlightened

A concave mirror (on the wall, sufficiently distant) rotates the image 180 degrees — noAxioms
So, Lewis Carroll proved that what we see in the "looking glass" is actually a separate dimension where everything is reversed from the normal world. Now it all makes sense. :joke:In other words, what we see in a mirror is an optical illusion? — Gnomon
Assuredly not! As this paper by a famous mathematician demonstrates. — unenlightened
