Demetrius Mutieff. After work in Bulgarian government archives and SIBAL, Demetrius Mutieff's contribution in theoretical physics and metheorology in XIX century was marked for the first time [1, s. 165-208]. His activities in Russia (1843 1856) is not clear yet . Doctorate thesis "De Psychrometria" (1842) was fond in Bulgaria .
Textbooks on Physics and Mathematics in XIX century. Working with archives of Nayden Gerov [2, pp. 229-293], Joakim Gruev [2, pp. 229-293], Emanuil Vaskidovich , Bulgarian Central eparchial school in Plovdiv , , ,  and textbooks on mathematics  and physics , published up to 1878 the sources, used by Nayden Gerov are found , and the stages are defined.
Education on Physics expressing by Bulgarian secondary school curriculums and textbooks are examined up to 1925.
Physics in the Sofia University from 1889 to 1950 , : Lectures , and scientific results of Prof. P. Bachmetiew , , Prof. G. Maneff [30-31], , , Prof. G. Nadjakov [ิ1], , independent physics speciality creation ,  and education in doctorate in physics in Bulgaria during the thirties of XX century  are determined.
Milko Borissov , . In the field of solid state physics  Milko Borissov worked with one hundred co-authors and made 403 publications in 30 different areas, because his research model has cyclic direction between science reports, patented inventions, and manufactured technologies . Semi-conductors mono-crystal growth has great importance for Bulgarian solid-state physics experiments during the second half of XX century [ิ2]. Milko Borissov's research on history of physics has two stages. He examined development of the physics in Bulgaria mainly , .
