On Information and Adventure

Information and entropy are closely related: Infrequent events carry more information than frequent ones; or, in other words, the lower the occurrence probability of an event the higher its information content. The total information of all possible events is the sum over their individual information content weighted by their occurrence probability. Conversely, with more information, events can be predicted better. And low information means a high entropy, thus low predictability. This is commonly referred to as the Shannon entropy and does not only apply in computer science.

We took one week off before the Easter holidays, but it’s difficult to plan vacations in these uncertain times. For two days and one night we took our T4 and went out into the unknown towards the Southern Harz Mountains. With little information what to expect, what to do, or where to sleep. For me, the less information, the more it feels like adventure. If you want to read in detail what we did, check out the latest blog post from Mädchen Klitzeklein. I will just show some of the photos I shot.


Our sleeping location was on top of a small hill and there was a wonderful evening mood and night sky. The views were calming and the colors powerful. The sun set slowly behind a group of trees and left behind unusually warm air for this time of the year. After another hour, the full moon rose over the next town.


The morning started early at 6 p.m. with some shots of the distant wind turbines. I also couldn’t resist to try some macro captures with the morning dew. The sun reflected beautifully on all the water droplets in the background.


Most of all, I am proud of the following macro shots of toads, ants, and oil beetles. Oil beetles are rather rare in our region, but on one of our hikes we saw multiple ones on a single path. On another hike, we stumbled over a lonely toad on the way. Very excitedly I took some shots before it leaped into the deeper grass towards the water reservoir. When we hiked further, more and more toads were crossing our path, which culminated in a section where it was even becoming difficult to avoid stepping onto them. I made well over 100 photos, but these three are the ones I like the most. The capture of the ant on the tree trunk is also Mädchen Klitzeklein’s merit who evoked the ants’ interest.
