Imagine you are visiting a beautiful city. You got a lot of tips from locals and you want to explore the recommended museums, old bridges, the famous jazz bar and the market. The city is built on islands and you set the goal to visit all the sights, but to pass each bridge only once. Using this example, you will be introduced to the beauty and abstraction of mathematics. With the help of mathematical considerations it is deduced under which conditions you reach your goal and which way you have to choose. Almost 300 years ago, the Swiss mathematician Leonhard Euler already dealt with this combinatorial problem, which today is assigned to graph theory.
