Im Gedenken an Wolfgang Engelmann: Leidenschaftlicher Forscher, Lehrer und Künstler (26. Februar 1934 - 1. Juli 2023)
Woher kommt das Salz des Meeres und wohin geht es?
The dissolved salts in the sea come from freshwater tributaries, which contain a small amount of salt that remains in the sea as the corresponding water evaporates.

Die Steigbildmethode
Until the 1980s, the »Rising Picture Method« was valued in anthroposophical contexts as one of the »Picture-forming Methods« and was considered particularly suitable for making statements on the quality of plants and plant extracts.
