In 1735 Euler is faced with a trivial question that, according to him, has got little to do with mathematics.

**Is it possible to make a walk through the city of Königsberg, crossing each of the seven bridges once?**In this GeoGebrabook a historical math problem is brought back to life. Explore this simple but intriguing question that marked the start of a new branch of mathematics and learn about graphing. Experience yourself how math works by generalizing and modeling, ... and the genius of Eulers creativity.
