It is, among others, author of exercises in physics, published in numerous popular science publications, translator of scientific literature in the field of physics (including works by Albert Einstein, published in the university series: "Didactic Library of the Physics Teaching Methodology Team of the Institute of Physics of the Warsaw University of Technology". In 1985, he went to Algiers, where he lectured on continuum mechanics at the local polytechnic (L'Ecole Nationale Polytechnique).
