Notation for a representable functor

For an object $X$ of a category, $h_X$ is the contravariant functor represented by $X$, i.e. $h_X = Hom(-,X)$.

A Cauchy filter on a space $X$ is a proper filter on $X$ that contains sets (meaning subsets of $X$) of arbitrarily small diameter?.

Why I hate physics
Still stalled on physics, so I was fooling around with a math puzzle today. I don't know where math puzzles come from. There are a lot of math puzzles out there but there are only so many really
great math puzzles of this particular type.
