topology A result in
topology stating that a continuous
comes from the fact that you can't flatten all the hair on a
hairy ball, like a tennis ball, there will always be a tuft
somewhere (where the tangential projection of the hair is
zero). An immediate corollary to this theorem is that for any
x such that f(x)=x or f(x) is the
antipode of x. Another
corollary is that at any moment somewhere on the Earth there
is no wind.
