History of Konigsberg Prussia - Kaliningrad Russia
A look at the history and geography of K�nigsberg, Prussia (present-day Kaliningrad, Russia).
Included is a brief discussion of Immanuel Kant and David Hilbert, who were from K�nigsberg.
Finally, I look at the Seven Bridges of K�nigsberg problem. In solving this math problem, Leonhard Euler created a new area of mathematics called Graph Theory.
