Kheder Al-Ahmad (1350 - 1445 AH / 1932 - 2023 AD ), a mathematician and senior professor in Arab universities, Palestinian - Syrian , has authored books, translations, and is interested in Arabizing mathematical terminology. He is a research professor at the University of Colorado Springs and the University of Southern California , and an associate researcher at the International Center for Theoretical Physics in Trieste. He is a member of the Mathematics Terminology Committee at the Arabic Language Academy in Damascus .
His birth and education
Khudr bin Hamed Al-Ahmad was born on Friday, Shaban 22, 1350 AH, corresponding to January 1, 1932 AD , in the city of Haifa , Palestine . Then, following the Palestinian Nakba in 1948, he was forced to move to Syria with his brother when he was sixteen years old. He settled in Damascus and completed his education there, obtaining a high school diploma with the highest ranking in Syria.
He wanted to study mathematics and physics, so he joined the Faculty of Science at Damascus University , from which he obtained a degree in mathematical and physical sciences in 1954 with first place in the faculty, then he obtained a diploma in education from the Faculty of Education at Damascus University in 1955. Then he was sent to complete his postgraduate studies in the Soviet Union , and he obtained a doctorate in mathematics with a specialization in ( celestial mechanics ) from Moscow State University in 1964. This specialization was one of the rare specializations, and it had no practical applications except in America and Russia, and between the two superpowers there was a race to develop it.
At Moscow University, he met his Damascene colleague, Makki al-Hasani al-Jaza’iri , who was preparing his research for a doctorate in nuclear physics . He is now the Secretary-General of the Academy of the Arabic Language in Damascus . The relationship between them became strong and their friendship remained close over the years until the death of Dr. Khader. Among the students who accompanied him in Moscow, who became prominent professors in their specializations, were: Dr. Mustafa Hamoulila (PhD in atomic spectra), Dr. Hafez Junaid (PhD in biochemistry ), Dr. Ghaleb Sayda (PhD in igneous and metamorphic rock petrology ), Dr. Anwar al-Imam (PhD in geophysics ), Dr. Ahmed Deeb Dashash (PhD in industrial medicine), Dr. Daad al-Husseini (PhD in elasticity), and Dr. Walid Hamouda (PhD in dentistry ).
Dr. Khader is fluent in Russian and English, and is familiar with French , in addition to his native language, Arabic.
His work and functions
After obtaining his doctorate, he returned to Damascus as a teacher at the university from which he graduated, and he rose through its ranks over three decades from 1965 AD until his retirement in 1995, and he obtained the rank of professor in 1980 AD.
He was seconded to King Saud University in Riyadh , Saudi Arabia, for five years in two stages; the first in the late 1970s, and the second in the mid-1980s, and wrote some university books for its students. He worked as a research professor at the University of Colorado Springs and the University of Southern California in the United States of America in 1986 during the academic sabbatical year, and as an associate researcher at the International Center for Theoretical Physics in Trieste, Italy from 1991 to 1995. He worked as an expert and consultant at the Daaboul Industrial Group in Damascus from 1995 to 2012.
He received many tempting offers from international universities in America and Russia, but he declined and preferred to stay in his beloved city, Damascus, teaching its university students.
He participated in several conferences, seminars and working sessions in: Syria , Jordan , Saudi Arabia , Italy and the United States .
He is a member of the editorial board of the Damascus University Journal, and a member of the Mathematics Terminology Committee at the Academy of the Arabic Language in Damascus . The committee was formed in late 2009 and includes the following members: Makki al-Hasani, Secretary-General of the Academy; Muwaffaq Daboul, a member of the Academy (chairman of the committee); Marwan al-Bawab, a member of the Academy and current vice president; Khader al-Ahmad, an expert; and Bashir Qabil, an expert. The committee’s mission is to develop appropriate equivalents for foreign mathematics terms, and to express an opinion on terms and equivalents submitted to the Academy by universities and other institutions.
He left Damascus in 2012 to join his sons in Germany, until his death.
