Amazing Math! Welcome to Math E 320 2022 HD

This is a short welcome to the spring 2022 class in Math E 320. As usual in the first hour, we also look at some mathematical topic. This year it is the mathematics of mazes. A fancy mathematical definition of a maze is a spanning tree G in a graph K with two points A,B. The problem is to get from A to B when walking only in G.In the case of a maze in the plane, the walls or hedges are again a spanning tree. This insight leads to the Euler formula V-E+F=2. We will discuss mazes in the first class.
