The Inner-Austrian environment has been one of the main centers of Bošković’s science at the end of the Jesuit period. A century later, the same environment supported atomism and statistical physics of Jožef Stefan who was born in the then suburbs of Klagenfurt, and his student Ludwig Boltzmann, who married a half Slovenian. The socio-pedagogical structure of Austrian lands proved in both cases to be the ideal network for the dissemination of dynamical and statistical theories of atoms. We can expect new advanced contributions from the same Central European environment in the 21st century. Jesuit professors in Inner Austria and in territories south of it focused their knowledge in Graz, and at the same time they deliberated it in missions inside and outside the Province of Jesuits. Gabrijel Gruber spread the domestic success of Jesuit knowledge worldwide, after he tested his main experiments about the possibilities for modern ship propulsion upstream on the Mura river and regulated the flow of water on the Ljubljanica and Drava river below Ptuj and Maribor. As the Jesuit General he then transferred the reputation of the Inner-Austrian and especially Slovenian Jesuit knowledge from Russia to the USA so successfully, that the protestant president George Washington sent his nephews to Gruber’s Georgetown school near the capital Washington; that is why the entrance hall of the University of Georgetown is today still symbolically adorned with the portrait of the well-known Jesuit teacher from Slovenian circle G. Gruber, who is therefore not only a symbol of knowledge.
