Andrzej Kajetan Wróblewski works at the Institute of Experimental Physics of the Physics Department, Warsaw University. He specializes in elementary particle physics (high energy physics) i.e. Soft Hadron Physics (1990), New AMY and DELPHI multiplicity data and the log-normal distribution (with co-authors; 1990), Genesis of the lognormal multiplicity distribution in the e² e²- collisions and other stochastic processes (with co-authors; 1990), Mystery of the negative binomial distribution (with co-authors; 1987), Constraints on multiplicity distribution of quark pairs (1985). His books on the history of physics are mainly in Polish: Truth and Myths in Physics' (1982); History of Physics' (2007). He is also co-author (with J. A. Zakrzewski) of the Introduction to Physics' (vol. 1 1976, vol. 2, part 1-2 1989–1991).
