Milan Raspopović (Serbian Cyrillic: Милан Распоповић) was one of the members of the commission for the establishment of Mathematical Gymnasium Belgrade (abbr. MG) in 1963. He was the first MG physics professor from 1966, and the creator of the MG Physics Curriculum. He was also an MG professor of electronics, and MG principal and director, elected to office in 1970. Raspopović served in parallel as both Principal and Director of Mathematical Gymnasium Belgrade for 32 years, until his retirement in 2002. Education Milan Raspopović received his PhD degree in Physics and Philosophy from University of Belgrade. He successfully defended his PhD thesis entitled "The impact of Ludwig Boltzmann’s teachings and understandings on physics and philosophy" at the Faculty of Electrical Engineering, University of Belgrade. Career Raspopović was the first professor of Physics at Mathematical Gymnasium Belgrade – Special Mathematical Gymnasium (a school of Special National Interest), and the creator of the school's unique physics and overall curriculum. Raspopović taught university level courses at University of Belgrade, University of Niš, University of Kragujevac, and University of Montenegro. During that time he was principal and director at Mathematical Gymnasium Belgrade. Raspopović and Emilo Danilović, then Serbian Chief Scientific Advisor for physics, created the first MG curriculum in physics. Textbooks Raspopović is the author or co-author of over 30 textbooks and collections of assignments in physics, for elementary and secondary schools. In the area of physics for elementary schools, as well as in the area of textbooks and collections of assignments for high schools of technical sciences (electrical engineering and mechanical engineering), for high schools of natural sciences and mathematics and natural science curricular stream in gymnasiums, in didactics, and including his special physics textbooks for Special School for Gifted Matematička gimnazija, professor Raspopović's books have the largest circulation in Serbia, Montenegro, and in former Yugoslavia. Raspopović also co-authored textbooks and collections of solved problems with professors from Mathematical Gymnasium. Awards Raspopovic was awarded the Sretenje Order (3rd class) in February 2015, "for special merits for the Republic of Serbia and its citizens in educational and pedagogical activities". International results Raspopović led the school as its principal and director for 32 years. During that time, the school achieved unique results worldwide regarding the number of gold, silver, and bronze medals won at the International Science Olympiads: International Mathematical Olympiads, International Physics Olympiads, International Olympiads in Informatics, International Astronomy Olympiads, International Olympiads on Astronomy
