the projective plane: or, how to make ends meet
abstract:
we discuss the problem of how to find the number of simultaneous solutions to two polynomial equations in two variables. this amounts to calculating the number of intersection points of two curves in the plane. we discuss why this question has a much nicer answer if one is wily enough to replace the usual $(x,y)$-plane with something else.
