We are hereby presenting a didactic concept for an advanced lab course that focuses on the design of donor materials for organic solar cells. Its research-related and competence-based approach qualifies the students to independently and creatively apply computational methods and to profoundly and critically discuss the results obtained. The high…

Harnessing energy from the tides is a much-promoted but rarely realised way of generating electricity. This article examines some of the systems that are currently in use or under development, and outlines their economic, environmental and technical implications.

Criticizes a proposed approach to teaching physics in terms of energy carriers (SE 532 196), arguing that it requires energy to be thought of as a substance which can flow. Discusses problems related to concept formation and logical difficulties with the curriculum, considering several contradictions to physics principles which may arise. (JM)
