UNESCO proclaimed 2015 as the International Year of Light and Light-based Technologies. The program includes discoveries in the field of optics, photonics and electromagnetic signal transmission, and it also marks the 100th anniversary of registering seven patents of Michael Pupin from the field of radio-waves emission.
The light made revolution in the filed of energy, education, agriculture, health and communications. Mesmerised by the light, Pupin understood the lighting not only as a technological innovation, but also as a cultural change.
Michael Idvorsky Pupin (1854-1935) was a scientist, professor, winner of Pulitzer prize, Honorary Consul of Serbia in the USA, long-term president of the Serbian National Alliance in the USA, great benefactor and patron.
During his many years of scientific and experimental work, Pupin gave significant contribution to the field of multiple telegraphy, wireless telegraphy, telephony, radiology and development of electrical engineering.
With his patents from 1915, he laid the foundations for the long-distance multi-wave transmission of radio signals by electronic transmitters, thus creating the basis for the development of radio techniques and all forms of modern wireless communication.
