Today, four years have passed since the death of world-famous Azerbaijani scientist, founder of fuzzy set theory and fuzzy logic, professor at the University of California, Lotfi Zade.

Tehsil.biz looks at some aspects of the life and activity of prominent scientist Lotfi Zadeh on the day of his remembrance.

Born on February 4, 1921 in Baku, Lotfi Rahim oglu Alasgarzadeh completed his primary education at secondary school No. 16. In 1932, the Alasgarzade family moved to Iran. After graduating from high school here, Lotfi Zadeh was admitted to the Faculty of Electrical Engineering at Tehran University. After graduating from university, he moved to the United States at the age of 23 and continued his education at the Massachusetts Institute of Technology. The foundations of his six important theories known to world science were also laid there.

Lotfi Zadeh received his master's and doctoral degrees from 1944 to 1959 at the Massachusetts Institute of Technology and Columbia University. From 1959 he worked at the University of Berkeley, and from 1963 he headed the Department of Electrical Engineering and Computer Science. He was a lifelong professor at the university and director of the Soft Computing Institute.

The Azerbaijani scientist had a theory of fuzzy logic (Fuzzy Logic), which became famous in the world and was widely used in production, as well as a revolution in world science. This theory gave a new expression to the concept of binary sets, which is the basis of mathematics: fuzzy sets. The introduction of fuzzy measurements in science has made it possible to take more adequate account of the uncertainty of the processes taking place in nature and in society. Japanese companies such as Mitsubishi, Toshiba, Sony, Canon, Sanyo, Nissan, Honda and others have been producing photo and video cameras, washing machines and vacuum cleaners using fuzzy logic technology. , are widely used in the management of trains, industrial processes. He is also the author of scientific discoveries that played an important role in the development of world science, such as "Theory of Impressions", "Systems Theory", "Word Theory Computer", "Optimal Filter Theory". Books about him "The coryphaeus of modern science", "The world can not live without geniuses", the documentary "Far and near Lotfi Zadeh" were made, the Lotfi Zadeh Association of Heritage and Artificial Intelligence, the International Academy of Modern Sciences named after Lotfi Zadeh were established.

The scientist's famous situation space, control and observation theories of dynamic systems form the basis of modern control science. The US National Aeronautics and Space Administration (NASA) studies, designs and implements control systems based on these theories.

Lotfi Zadeh's rich scientific activity has always been highly appreciated by the Azerbaijani state. In February 2011, according to the relevant decree of President Ilham Aliyev, the world-famous scientist was awarded the Order of Friendship for his contribution to the development of technology and the establishment of intercultural dialogue. On January 21 this year, President Ilham Aliyev signed an order "On the celebration of the 100th anniversary of prominent scientist Lotfi Zade."

The world-famous scientist last came to Baku in November 2008 to participate in the BakuTel international exhibition and conference of telecommunications and information technologies. Lotfi Zadeh took part in the event organized by the Presidium of the Azerbaijan National Academy of Sciences (ANAS) and was awarded an honorary diploma of ANAS for his services in science.

At the meeting of the Presidium of ANAS held on April 20, 2016, the great scientist was awarded the "Gold Medal of the Republic of Azerbaijan named after Nizami Ganjavi". In 1989, he was awarded the highest Honda award given to Japanese scientists for his industrial achievements in fuzzy logic theory.

Lotfi Zadeh was the only person to be elected a lifelong professor at the University of Berkeley. He was a leading expert on NASA and NATO. He also headed the Zadeh-ZIFT Institute of Information Technology in Berkeley, where he lives. Lotfi Zadeh is the second scientist in the world after the German scientist Max Planck to establish a scientific center named after him and his theory.

Lotfi Zadeh, a member of many foreign academies, has been awarded prizes and medals by many prestigious societies and foundations. He has been an honorary doctor of dozens of foreign state and public organizations. The world-famous scientist, as well as a member of the US National Academy of Engineering, was elected an honorary academician. He was also the honorary editor-in-chief of the "Problems of Information Society" and "Problems of Information Technologies" magazines of the Institute of Information Technologies of ANAS.

The scientist's son-in-law was brought to Azerbaijan in accordance with his will and was buried in the first Alley of Honors.
