Abstract
It is like an irony of the history of science that philosophy of chemistry emerged at a time when disciplinary research became increasingly replaced with transdisciplinary problem-orientated research. From bio-medical research via materials science to nanotechnology, chemists and chemical approaches are strongly involved in these areas. If the boundaries of the philosophies of science were to be defined by the boundaries of classical disciplines, we would not only get into demarcation troubles but also miss some of the most fascinating recent research fields. One such field is the study of the dynamics of the stratosphere, which in the 1970s, by the calculations of two chemists, turned from marginality to the greatest importance to securing future conditions of life.
