contributor to the birth of commercial electricity in the United States. Other notable Serbian scientists and inventors were Mihajlo Pupin and Milutin Milanković.
• Nikola Tesla was famous for developing the AC motor, the bifilar coil, various devices that used rotating magnetic fields, the alternating current polyphase power distribution systems, the fundamental devices of systems of wireless communication (legal priority for the invention of radio), radio frequency oscillators, devices for voltage magnification by standing waves, robotics, logic gates for secure radio frequency communications, devices for x-rays, apparatus for ozone generation, devices for ionized gases, devices for high field emission, devices for charged particle beams, methods for providing extremely low level of resistance to the passage of electrical current, means for increasing the intensity of electrical oscillations, voltage multiplication circuitry, devices for high voltage discharges, devices for lightning protection and VTOL aircraft. He also invented the Tesla coil and the Tesla turbine . The tesla is the SI derived unit of magnetic flux density and was named after Tesla.
• Mihailo Petrović is known for having contributed significantly to differential equations and phenomenology, as well as inventing one of the first prototypes of an analog computer.
• Milutin Milanković is known for his theory of ice ages, suggesting a relationship between the Earth's long-term climate changes and periodic changes in its orbit, now known as Milankovitch cycles.
• Mihajlo Pupin discovered a means of means of greatly extending the range of long-distance telephone communication by placing loading coils of wire (known as Pupin coils) at predetermined intervals along the transmitting wire (known as "pupinization").
• Miodrag Radulovacki is best known for postulating
