Abstract

The XXXI Conference of the Baltic Association of the History and Philosophy of Science (BAHPS) was held on 13–16 June 2024 on the premises of the University of Tartu, Estonia. The conference titled ‘Scientific Instruments in History and Philosophy of Science, Technology and Medicine’ celebrated the bicentennial anniversary of the completion and acquisition of the large astronomical instrument. The telescope, called the Great Dorpat Refractor, was made by Joseph Fraunhofer and until now remains housed in the same place—the Old Observatory of the Tartu University.
