s = 1 + 2s, s = infinity

The problem is that infinity is a fixed point of every map z -> c + rz,
for finite c and nonzero r, so this gives infinity as an alternate
solution of every geometric series.  It seems a little less remarkable
that way.  I wish someone could tell us what Hardy actually said about
this.  - Dan Hoey 23:35, 17 April 2007 (UTC)
