The nearsighted man
I heard this problem from a teacher a couple weeks ago -
A nearsighted man can see things only if they’re 3 feet or closer. If he stands 2 feet in front of a mirror, can he see his reflection?
He said he consistently finds people split on this, and hasn’t found a compelling proof one way or the other. I humbly offer up the following “proof without words” – but what does it show?
