Alkhawarizmi

780 - 850 AD

Muhammad bin Musa al-Khwarizmi was a contemporary of the Abbasid caliph al-Ma’mun, who realized the virtue of this Arab world and lavished blessings on him and gave him great care.

He is an Arab scholar who is proud of him in all ages, as he is the innovator of the science of algebra, the one who laid its foundations, and the innovator of calculating logarithms, and for this reason he was called (the father of algebra). It is believed that he took part in measuring the earth's circumference during the days of al-Ma'mun.

He excelled in the sciences of arithmetic, astronomy, and geography, as well as in the sciences of the body, and he was the first to use algebraic expressions, and his algebraic equations are used to this day, such as:

2x + 5x = 24 or 2x + 5x = x2

Al-Khwarizmi was the first to solve algebraic equations of the second degree, and he also surrounded the knowledge of his time and emerged in many of them, such as astronomy, geography, and arithmetic.
