I love me some Fermi problems! However, there are no good instructions on how to use them in classes. So I wrote it up! If you read this it, you will finally learn the answer to the question 'How much phosphorous is released each day by viruses lysing Prochlorococcus cells?' tinyurl.com/2njt9r8h

An diesem FAZ-Interview mag man einige Leerstellen kritisieren, man mag sich wundern, was unerwähnt bleibt, aber die Fakten des Ökonomen Joachim Ragnitz bezogen auf die West-Ost-Transferleistungen wie auch seine Prognose sind kaum zu widerlegen. Auch dieses Interview wird schäumende Wut bringen

Ukraine macht gleich in der ersten Zeile das Thema klar: "green into rust". Beim "great oxidation event" vor ca. 2.5 Milliarden Jahren lernten grüne Cyanobakterien, Photosynthese zu betreiben. Sie erzeugten Sauerstoff, der die Erde mit rötlichem Rost überzog, ähnlich wie am Mars heute. #ESC2026
