Chemische Oszillationen und Strukturen als Grundlage einer zeitlichen und räumlichen Organisation

Temporal and spatial coordination of many subprocesses is necessary for the evolution and preservation of living structures. It is likely that oscillatory chemical and biochemical reactions mimic principles of this coordination, since they also develop integrated spatiotemporal structures. The basic properties of such reactions are described, and a microbiological example is used to demonstrate that these phenomena may be important to morphogenesis.     

Krebs als Funktion von Disposition,Exposition und Alter

Essential parameters in carcinogenesis are the genetic and extragenetic disposition of an individual, its exposure to chemical, physical or viral influences in the environment as well as its age as the time that is needed to induce cancer. Cancer prevention seems only possible by reducing the exposure. It will be discussed whether the increase in life expectancy has become so important during the past decades that it compensates all efforts of reducing the exposure.     

Naturwissenschaft und Ethik als paradoxe Schöpfungen der Vernunft

The contradictory relation between Western science und ethics is attributable to the paradoxical nature of human reason. For the fundamental, intuitive (or Kantian a priori) concepts, thanks to which we construct reality from experience, turn out to be, au fond, mutually inconsistent. By contrast, the Far-Eastern world-view seeks to repress reason and thus avoid its troublesome paradoxes.
