Technical writer with interest in science (#Physics, #Astronomy, #Astrobiology, #ClimateResearch, #Geology, ...). I love riding bicycle, studying the evolution of #Landscapes, #Photography. A friend of enlightenment and science. Upset with racists, antisemites, and people being indifferent to those (#Antisemitism). I can't get into esotericism much; in fact, I even consider some of its excesses to be dangerous. Unless otherwise noted, shared photos are my own. Toot in English and German.
