A Mirror Image? Maybe Not.
A curious little factette spotted over coffee this Thursday morning.
When we look in a mirror, our left and right sides appear to be reversed – left is right and right is left. In fact, what has really happened is that the mirror has inverted us front and back. The reason that we think it is a left-to-right reversal is that we are used to a person’s left and right being reversed when they turn to face us. So what is the mirror doing? Imagine a person with their back to us doing a hand stand to face us, rather than turning around – their right and left remain the same but their top and bottom swap. Looking into a mirror has the same effect: nothing reverses in the mirror – not bottom and top, not left and right.
From an interesting list of ten common misconceptions. It’s worth a read.
