Matthias Kleiner find nothing more important to discuss than a federal minister’s doctoral thesis, this affair has now definitely been cut down to size. The Horror That Puts And yet all these topics can be seen in connection. After all, it is the best science that can provide the most effective help. And only a research community that Everything in Perspective values integrity above all else will be taken seriously and accepted as helper. Allow me therefore to make a few comments on the two events that were on our minds Between humility and helpfulness: The disaster in Japan is also a turning point for the during the weeks prior to the disaster. scientific community. What tasks it must tackle now, how it can help in big and small One of these events turned the world upside down ways – and what both have to do with integrity and excellence by incriminating and indicting the research community even though it was the actual victim. We must counter such degradation – which was careless at best, coldly calculated at worst – with our most elementary prin- ciples of honesty, truthfulness and trust, as well as the rules of good scientific practice, and we must shed light on the facts. And this is exactly what the research com- e still have the dramatic media images before with special poignancy.
