In this paper we study research trends in condensed matter physics. Trends are analyzed by means of the number of publications in the different sub-fields as function of the years. We found that many research topics have a similar behavior with an initial fast growth and a next slower exponential decay. We derived a simple model to describe this behavior and built up some predictions for future trends.

In the 1950s five books on sexology — in a broad sense — were published in German under the name of ‘Carl van Bolen’. However, the man and the author ‘Carl van Bolen’ never existed. Who then wrote the books? My preliminary investigation did not yield an answer. In fact, during my research the mystery only deepened.
