Making a little test with a new kind of blog post format where I explore some interesting fact related to geography and some history and fact around it.
For this first one I was going to take a look at the mathematical problem involving the bridges of Königsberg (present day Kaliningrad).
I have an old mathematical chart that I got from my father:
So, the subject of this post is the problem with the seven bridges of Königsberg in what was back in Leonard Euler's days in the 18th century Prussia (nowadays Kaliningrad, today a Russian enclave surrounded by Lithuania and Poland). In those days the two islands of city was connected by seven bridges and a common passtime of the recidents was to try to come up with a way of performing a walk crossing all the bridges, but only cross each bridge of time (https://en.wikipedia.org/wiki/Seven_Bridges_of_K%C3%B6nigsberg)
The central island that the town center in Euler's days, is now a park (it was devastated during WWII)
