A Master of Science (Latin: Magister Scientiæ; abbreviated M.Sc., MSc, M.Sci., M.Si., Sc.M., M.S., MSHS, MS, Mag., Mg., Mgr, S.M., or SM) is a postgraduate academic master's degree awarded by universities in many countries. The degree is typically studied for in the sciences including the social sciences.

In Brazil, Argentina and Uruguay, the Master of Science or Magister is a postgraduate degree of two to four years of duration. The admission to a Master program (Castilian: Maestría; Portuguese: Mestrado) in an Brazilian, Argentine or Uruguayan University requires the full completion of an undergraduate degree, as well Licentiate's degree as Professorate degree of four to five years long from any recognized university. Under the accomplishment of the Magister Scientiæ thesis dissertation, that in years of formal education, is generally equivalent to a Ph.D. or Doctorate in universities of North America or Europe given the Bologna comparison system among academic programs.

Australian universities commonly have coursework or research based Master of Science courses for graduate students. They typically run for 1–2 years full-time, with varying amounts of research involved. Research based Masters degrees are usually accompanied by an extensive thesis before completion. In some universities, as in the University of Melbourne an intensive 1 year Master is offered before getting into the Ph.D program with the name of "Bachelor of Science with Honours".

Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian-American inventor, physicist, mechanical engineer, electrical engineer, and futurist. He was an important contributor to the use 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 in the village of Smiljan (now part of Gospić, present day Croatia), Tesla was a subject of the Austrian Empire by birth and later became an American citizen. Because of his 1894 demonstration of short range 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.
