All papers of this edition give an opportunity for reflection on the chances, challenges and difficulties associated with the long-term transformation of higher education and scientific activities. Therefore, the concept of "scientific excellence" has been perceived as a guiding idea in the academics' efforts. On the other hand, it seems to be an ideal that can never be achieved but towards which one ought to strive persistently. Furthermore, the pursuit of excellence is accompanied by contradictions which have been pointed out many times in the history of academia in Poland. This publishing series embodies the belief in the existence of the so-called invisible college, i.e., the research community, exemplified by young scientists starting their academic path inspired by recognized professors.
