Topography and Topology

Maps and Mathematics: How many different colors must you have available if you want to color a map so that countries that share a boundary line are not colored the same color?

The Problem of the Young Map Colorer: Using as few crayons as possible, help the young child successfully color each map

 General Topics in Topology: good general website for an overview of topology

Konigsburg Bridge Problem: This site explores the problem and solutions which inspired the great Swiss mathematician Leonard Euler to create graph theory, which lead to the development of topology.
