Huseyin Yilmaz

from Wikipedia, the free encyclopedia

Hüseyin Yılmaz ( cited in English as Huseyin Yilmaz ) (born August 13, 1924 in Acıpayam , Turkey ; † January 27, 2013 in Cambridge , Massachusetts ) was a Turkish -born American theoretical physicist .

Career

Yılmaz, who was orphaned at an early age (at the age of 12), studied electrical engineering at the Technical University in Istanbul (bachelor's degree in 1950, master's degree in 1951, where he received an award as the best graduate of his class) and from 1952 at MIT , where he was in 1954 PhD. 1954 to 1956 he was an assistant professor in physics at the Stevens Institute of Technology . In 1956 he was with the National Research Council of Canada. From 1957 he was with Sylvania Electric Products. In 1958/9 he worked at the Institute for Advanced Study in Princeton, from 1962 as Senior Staff Member in the development department of Arthur D. Little Inc. (and at the same time in the Biological Faculty of MIT) and in 1964 at the Institute for Perception Research in Eindhoven . He later owned Perception Technology Corporation in Winchester, Massachusetts , and in the 1990s he worked at Tufts University's Electro-Optics Research Center and Hamamatsu Photonics .

Yılmaz dealt with the theory of gravity and from the 1960s on the perception of colors and language understanding. From 1960 he developed a theory of color perception that was based on the theory of evolution and was inspired by the work of Edwin Land .

As early as 1958 he published a controversial theory of gravity, which in the limit case of weak fields corresponds to the general relativity theory (since it leaves one side of the field equations, the Einstein tensor, unchanged, but the energy-momentum tensor, i.e. the "other side" of the field equations , added a gravitational contribution), but no event horizons (and thus no black holes ) and (according to Yılmaz) also no big bang and no expanding universe. Yılmaz further claimed to have found a discrepancy in general relativity (no attraction for closely spaced, infinitely extended parallel thin plates), which was also disputed (by Clifford Will and William Unruh and Edward Fackerell). Yılmaz's motivation was the search for a theory of gravity that is compatible with quantum mechanics.

In the 1970s he dealt with the philosophy of science.

In 1959 he received the Gravity Research Foundation Award for work on Maser experiments to test general relativity. In 1965 he received an honorary professorship from Northeastern University.

His son Lev Yilmaz (* Levni Yilmaz, 1973) in San Francisco is a filmmaker (author of a series of cartoon films Tales of mere existence ).
