Boundary definition

On interesting thing about mathematical discoveries is that the original problem over time becomes less important as new uses for it are developed. The problem with property boundaries is that their definitions are too often rooted in a history of exploitation and violence, not in the nature of the land. Gary Snyder has said that political boundaries should outline watersheds, but governments invested in their arbitrary borders should not be expected to agree.
