Das Jahrzehnt des Gehirns (Neunzigerjahre des letzten Jahrhunderts) hat eine Flut von Veröffentlichungen gebracht, die anhält und immer noch am Steigen ist. Auffällig ist dabei unter Anderem, dass erstens meist Detailfragen über das Funktionieren von Gehirn und Nervensystem... Read More

La méthode de cristallisation sensible, désormais appelée cristallisation avec additif, pour souligner le caractère volontaire de l’ajout, est un phénomène faisant intervenir une foulitude de paramètres expérimentaux dont la variabilité influe sur sa reproductibilité. Il s’... Read More

Das Buch von Volker Harlan verdankt seinen Inhalt umfangreichen Studien des Autors, besonders auch seiner Arbeit mit dem teilweise unveröffentlichten Nachlass von Beuys und Klee. Der Inhalt gliedert sich in sechs Kapitel: 1. Naturphilosophische und naturwissenschaftliche... Read More

Butterflies are fascinating creatures. Although most of us know little about their biological task in biotopes, they are greatly admired for their obvious contribution to the ensoulment of landscapes. What exactly does this concept mean? In the present study an attempt was... Read More

Wenn die Bildschaffenden Methoden zur wissenschaftlichen und gesellschaftlichen Anerkennung gebracht werden sollen, bedarf es einer interdisziplinären Zusammenarbeit von Persönlichkeiten aus Forschung und Anwendung, die in einem intensiven, vorurteilsfreien und praktischen... Read More

Path curves are fundamental constructions of projective geometry. They might also serve as single-parametric archetypal forms in the plant and animal kingdom. This hypothesis is based on the observation that a large variety of buds, cones, and eggs show a striking similarity... Read More

Rudolf Steiner proposed that in the twelfth school year at the Waldorf School chemistry should be taught in its most intimate connection with man. ‘It would be desirable to have an inorganic, an organic, an animal and a human chemistry.’ In this connection too, the metal... Read More

How has education in chemistry developed during the 80 years of the Waldorf-School movement? The main points up to the present day are characterized, beginning with the approach of Eugen Kolisko. The obvious shortcoming is a special problem of this discipline. Some reasons... Read More

Intensified research on global biogeochemical cycles in recent decades has led to a holistic concept of the earth, i.e. that it is considered as a self-regulating system, a whole, the biosphere and even as an organism. Besides the vegetation on the continents, particular... Read More

This contribution deals with the connections to be found between reductionist and phenomenological chemistry. How can molecular thinking be linked with the manifest properties of substances and above all with the world of human perception? A ‘multi-level chemistry’ is... Read More

We know from the history of arts and crafts that early experience of ‘practical chemistry’ dates back to very early times. Apart from the production of materials such as metal, glass and clay as well as tanning and dyeing, fermentation processes used in food production and... Read More
