Ebu Muhammed Han Hamid el-Hamid b. el-Hıdır el-Hocendî

Mathematician and scholar of astronomy
(B. 930, Hocend / *It
is revealed by the Turks in Islamic civilization, one of these Turkish scholars
is Ebu’l-Mahmud el-Hocendî”.*

After his initial education in Hocend, he
was oriented to mathematics and other sciences, he grew up in the deep-rooted
madrasahs in the

**Hocendî examined the **“X^{3}+Y^{3}+=Z^{3” }**formula
for the first time among the mathematicians of Islam and **seriously
dealt with this uncertain equation and **showed that the equation
could not be solved with integers. Thus, he became the **mathematician
who founded the equation in question before Fermat, who had tried to own the
equation with the “Fermat's Theorem” title. The proof of this theorem that is
referred as the “Fermat's Last Theorem” in the history of mathematics could
only be made in 1995; according to that, it is understood that Hocendî had found
this theorem 700 years before Fermat did.

This
situation has been like this most of the time; western sources always stated
the names of mathematicians in the Western world as the founder and developer
of mathematics.

In fact, Europe improved the
mathematics in between 8^{th }and 16^{th} centuries by making
use of the major works that had been prepared by mathematicians of Turkish-Islamic
world. The truth is; mathematicians of the Turkish-Islamic world fed the
scientific thought and research sensitivity of the Western world by sparking it
and brought in a new vitality in this field. They carried the West to a level
where they could progress, based on their views and
inventions on algebra, geometry, arithmetic and trigonometry. In fact, **Halid bin Hıdır el-Hocendî
**revealed** the **integral equation, which stated that the sum of two
cubes would never be a cube, hundreds of years before Fermat **(1610-65). **

Hocendî, who was also a talented scholar of
astronomy, made astronomical observations in Rey in the middle of the 1600s and
measured the “eclipse plane”, in other words, the slope of the elliptical.

El-Hocendî, who was one of the most famous
mathematicians of his time, wrote works on astrolabe (astronomy measuring
device), algebra and number theory. In these works he revealed interesting
ideas and solutions compared to his time for the spherical triangles, solutions
of the uncertain equations and sine equations. It is known that this great
scholar of math, algebra and astrolabe closed his eyes to life in 1000.
