-**Important Related Concepts:**+<​blockquote>​One of the things we observe in everyday life is that things have a distinct left and right. The simplest case is just the hands of a humanObviously, the left hand and the right hand are different from each other. That is a very general thing in nature that things can be 'like a left hand' or 'like a right hand'. Of course, they do not need to be so. A ball has obviously no distinct left or right. But things can have. This fact is known in science as chirality, originating from a Greek word for hand.
