A world-renowned Azer­bai­jani sci­en­tist, founder of fuzzy logic Lotfi Zadeh passed away on Septem­ber 6 at 7:30 am Cal­i­for­nia time aged 96. The worldrenowned sci­en­tist, Lotfi Zadeh, was a pro­fes­sor emer­i­tus of com­puter sci­ence at the Univer­sity of Cal­i­for­nia, Berke­ley, and the di­rec­tor of the Berke­ley Ini­tia­tive in Soft Com­put­ing.

Aworld-renowned Azer­bai­jani sci­en­tist, founder of fuzzy logic Lotfi Zadeh passed away on Septem­ber 6 at 7:30 am Cal­i­for­nia time aged 96.

The world-renowned sci­en­tist, Lotfi Zadeh, was a pro­fes­sor emer­i­tus of com­puter sci­ence at the Univer­sity of Cal­i­for­nia, Berke­ley, and the di­rec­tor of the Berke­ley Ini­tia­tive in Soft Com­put­ing.

Pro­fe­sor’s son Nor­man Zadeh ear­lier stressed that Lotfi Zadeh's last will was to be buried in Azer­bai­jan.

The letter about the burial of Lotfi Zadeh in Azer­bai­jan was trans­ferred to a close friend of the Zade's, pro­fes­sor of the Azer­bai­jan Tech­ni­cal Univer­sity Shah­naz Shah­bazova, Az­er­tac re­ported.

Lotfi Zadeh, who is men­tioned in the same breath as Aris­to­tle and Al­bert Ein­stein, was born in Baku, Azer­bai­jan on Fe­bru­ary 4, l92l. The young Zadeh grew up in Iran. Grad­u­at­ing from the Univer­sity of Tehran in 1942 with a de­gree in elec­tri­cal engi­neer­ing, he went on to pur­sue a MS de­gree in elec­tri­cal engi­neer­ing at MIT, which he ob­tained in 1946.

Par­ents of Zadeh at this time lived in New York, where he en­tered the Columbia Univer­sity, and af­ter de­fend­ing his the­sis in 1949 re­mained there as an as­sis­tant in the engi­neer­ing de­part­ment.

Lotfi Zadeh is best known for propos­ing the fuzzy math­e­mat­ics in the 1960s. The the­ory of fuzzy logic caused a rev­o­lu­tion world­wide and en­tirely changed the con­cept of cy­ber­net­ics and played an im­por­tant role in space satel­lites, cog­ni­tion and the study of im­ages, the Earth and the Uni­verse, and in re­search into UFOs.

The essence of fuzzy logic is that the world is a va­ri­ety of shades - from black to white. To put it sci­en­tif­i­cally, in this world noth­ing is ab­so­lute in math­e­mat­i­cal terms, as ev­ery­thing varies to a cer­tain de­gree on a scale of 0-1, thus, be­tween zero and one there are dozens, hun­dreds, of other shades.The word "fuzzy" is used be­cause the bor­ders of white and whitish, scar­let and red are fuzzy; there is a con­tin­u­ous tran­si­tion from one to the other.

The the­ory is widely ap­plied in all ar­eas of mod­ern in­dus­try - robotics, me­chan­i­cal engi­neer­ing, elec­tron­ics, fifth and sixth gen­er­a­tion su­per com­put­ers and de­fense tech­nol­ogy.

The the­ory of fuzzy logic forms the ba­sis of fuzzy tech­nol­ogy through­out the world. The the­ory plays an im­por­tant role in the US space pro­gramme. In Ja­pan, cam­era and video equip­ment are pro­duced on the ba­sis of fuzzy logic while in Europe a va­ri­ety of “smart” sys­tems op­er­ate on fuzzy logic.

Fuzzy logic is not Pro­fes­sor Zadeh´s only the­ory. He de­vel­oped the the­o­ries of sys­tem and op­ti­mal fil­ters. The the­ory of op­ti­mal fil­tra­tion is a new step in mod­ern math­e­mat­ics, cy­ber­net­ics and com­put­er­i­za­tion, and is val­ued not only for its sci­en­tific orig­i­nal­ity, but also its prac­ti­cal re­sults.

The the­o­ries of mul­ti­ple val­ued op­ti­miza­tion and im­pres­sions in dy­namic sys­tems were also de­vel­oped by Zadeh.

Pro­fes­sor Lotfi Zadeh has re­ceived many hon­ors world­wide.
