If my high school maths teacher were here he'd say that a point is a zero-length line segment.

- ktizo 14y agoSometimes it is useful to think of a really short line becoming a point, like in calculus, but that doesn't mean a point is a really short line any more than its a really tiny triangle or anything else we want to scale to a point.
