Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian-American inventor, mechanical engineer, and electrical engineer. He was an important contributor to the birth of commercial electricity, and is best known for developing the modern alternating current (AC) electrical supply system. His many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries were based on the theories of electromagnetic technology discovered by Michael Faraday. Tesla's patents and theoretical work also formed the basis of wireless communication and the radio.
Born an ethnic Serb in the village of Smiljan (now part of Gospić), in the Croatian Military Frontier of the Austrian Empire (modern-day Croatia), Tesla was a subject of the Austrian Empire by birth and later became an American citizen.. Because of his 1894 demonstration of wireless communication through radio and as the eventual victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. In the United States during this time, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture. Tesla demonstrated wireless energy transfer to power electronic devices in 1891, and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project.
The University of Belgrade (Serbian: Универзитет у Београду / Univerzitet u Beogradu) is the oldest and largest university of Serbia.
Founded in 1808 as the Belgrade Higher School in revolutionary Serbia, by 1838 it merged with the Kragujevac-based departments into a single university. The University has nearly 90,000 students (including around 1,700 postgraduates) and over 4,200 members of teaching staff.
The University comprises 31 faculties, 8 research institutes, a system of university libraries and information centres, and the Belgrade University Library (Carnegie library). The faculties are clustered into five groups based on their academic characteristics.
Since its founding, the University has educated more than 330,000 bachelors, around 21,300 magisters, 29,000 specialists and 12,600 doctors.
