The Rosen commemorative issue of Chemistry & Biodiversity is now available. This project came to fruition primarily due to the efforts of Don Mikulecky of VCU, and this issue includes sixteen research articles plus Don’s editorial. The articles are diverse and touch upon a wide range of aspects of Rosen’s work, such as the Modelling Relation, entailment structures, the (M,R)-system model, relational biology and objectivity in science.
