The Museum of the History of Physical Sciences in Bulgaria, part of the Institute of Solid State Physics – BAS, researches, collects, preserves, and promotes sources related to the history of physical sciences through its exhibitions, reading room, and archives.
Through the permanent exhibition dedicated to Georgi Nadjakov, you will discover the inspiring story of the first name entered in the “Golden Book of Discoverers and Inventors in Bulgaria.
The office of Acad. Georgi Nadjakov at the Institute of Solid State Physics of the Bulgarian Academy of Sciences has been transformed into a permanent exhibition dedicated to his scientific achievements and significant contributions to physics.
In 2014, the office was declared a historical site by the European Physical Society.
Visitors have the opportunity to immerse themselves in the academic’s working environment, view original documents and scientific notes, and follow the development of one of the most significant discoveries in the history of physics in Bulgaria.
Georgi Nadjakov (1897–1981) was a distinguished Bulgarian physicist, a talented educator, Rector of Sofia University (1947–1951), and an active public figure. His research laid the foundation for the technology that eventually led to the invention of the photocopying machine.
Acad. Georgi Nadjakov was the founder of the Institute of Physics at the Bulgarian Academy of Sciences (BAS) and served as its director for many years. He succeeded in establishing a modern center for physics within the Academy, while also contributing to the development of industry in the country.
He was one of the founders and a member of the World Peace Movement, as well as a member and honorary chairman of the World Peace Council (1970–1980).
In 1937, Georgi Nadjakov’s discovery of photoelectrets at Sofia University sparked increased interest in the photoelectret state of matter.
The discovery is considered the first officially recognized scientific discovery by a Bulgarian researcher. His name is the first to be entered in the "Golden Book of Discoverers and Inventors in Bulgaria."
His research on the photoelectret state of matter laid the foundation for the technology that led to the invention of the photocopying machine.
The permanent exhibition is open for visits by prior arrangement.
