After a short introduction into the history of the building of the Physics Institute of the University of Breslau, the development under Otto Lummer is sketched: influenced by the newly founded Technische Hochschule, the building as well as the faculty, were enlarged. The collection of instruments for instruction and research was built up and the cooperation with industry and with guests from abroad strengthened. Young scientists were promoted, making Lummer’s institute into one of the leading ones in optics at that (...) time. (shrink)

Empathy facilitates everyday social interactions and has often been linked in the literature to prosocial behavior. Robust evidence has been found for a positive relationship between experiencing empathy and behaving prosocially. However, empathy, and the empathy–prosocial behavior relationship in particular, has been studied mostly in combination with negative emotions. Less research has been conducted on empathy for positive emotions, and the link between positive empathy and displayed prosocial behavior has not been intensively investigated so far. The purpose of the present (...) article is thus twofold: first, we review and summarize research evidence on empathy for positive emotions, and second, we propose that people’s motivation to maintain an experienced positive affect is a viable mechanism linking positive empathy and prosocial behavior.
