As part of the Hexagon mechanism project, the engineer Johann Wolfesberger and Oliver Conradt, the leader of the Section for Mathematics and Astronomy, have – over the past three and a half years – developed new inversion engines and have built prototypes. The first prototype moves two oloids, the second a ring of six oloids. MORE

In the early twentieth century Rudolf Steiner repeatedly mentioned projective geometry to scientists, mathematicians, teachers and artists. He pointed out that projective geometry could help to acquire forms of thinking which are fundamental for understanding life. MORE

Paper on bud research

In the framework of the research project Rhythmical Change of Shape in Mistletoe Berries According to Moon and Zodiac Constellations by Renatus Derbidge at the Natural Science Section of the Goetheanum a first paper was published in the open access journal PLOS ONE. It presents methods and software to capture and measure the shape changes of mistletoe berries and leaf buds over time. The paper describes the software used to automatize a number of tasks including contour recognition, optimization of fitting the contour via hill-climbing, derivation of the path curves, computation of Lambda and blinding the pictures for the operator. The validity of the program is demonstrated by results from three independent measurements showing circadian rhythm in mistletoe berries. The program is available as open source and will be applied in a project to analyze the chronobiology of shape in mistletoe berries and the buds of their host trees.

Coauthors of the paper are Linus Feiten (Faculty of Engineering, Chair of Computer Architecture, University of Freiburg, Freiburg, Germany), Oliver Conradt (Section for Mathematics and Astronomy, Goetheanum, Dornach, Switzerland), Peter Heusser (Centre for Integrative Medicine, University of Witten/Herdecke, Witten, Germany) und Stephan Baumgartner (Hiscia Institute, Society for Cancer Research, Arlesheim, Switzerland). The paper and further material can be found HERE.

Section for Mathematics and Astronomy

of the School of Spiritual Science at the Goetheanum, Dornach (CH).

The School of Spiritual Science, Goetheanum, is organized in different Sections, in the sense of faculties. The Mathematical-Astronomical Section is one of currently eleven Sections.

The task of the Mathematical-Astronomical Section includes research and teaching in the field of Mathematics und Astronomy in the sense of the Anthroposophical Spiritual Science as well as the coordination of the collaboration on a local, European and worldwide level.
