December Question – Man in the Mirror

It’s holiday season. After a full year’s work and study, we are all anxious for this well-deserved break. In addition to giving thanks, sending and receiving gifts, and participating in holiday activities, it is also time to look back at the past year and reflect.

This month’s question, is about reflection. We look in the mirror every day, and see our own image looking right back at us. However, something is a bit different. When I lift my right hand, the mirror image appears to lift his left hand. So left and right seem to be flipped. Yet, top and bottom are not flipped at all. If you think carefully about it, it should make absolutely no sense, because a mirror is a piece of glass that should treat left/right and top/bottom exactly the same way.

So why does a mirror image seem flipped in the left/right, but not the top/bottom direction? It’s a simple question, but not an easy question. Good luck and happy holidays.
