7 Math Fair 2024 - Work In Progress


What do knots, maps, mazes, driving directions and doughnuts have in common?  The answer is topology, a branch of mathematics that studies the special properties and connections of objects. Study the four color theorem, the mobius strip, Bridges of Konigsberg,  Euler Circuits, mazes, and more!


Bridges of Konigsberg & Euler Circuits

You’d have a hard time finding the medieval city Königsberg on any modern maps, but one particular quirk in its geography has made it one of the most famous cities in mathematics. Dan Van der Vieren explains how grappling with Königsberg’s puzzling seven bridges led famous mathematician Leonhard Euler to invent a new field of mathematics.
