Alkhawarizmi.

Al-Khwarizmi: Muhammad ibn Musa al-Khwarizmi, (b. 780 – died circa 850), Muslim mathematician and astronomer, whose major works introduced the Hindu-Arabic numerals and concepts of algebra into European mathematics.

• Known as “Abu al-Jabr,” a word that is derived from the title of his book, “Kitab al-Jabr”.

Al-Khwarizmi lived in Baghdad, where he worked at the House of Wisdom during the era of the al-Ma’mun caliphate.

He acquired the House of Wisdom and translated scientific and philosophical treatises, especially Greek, in addition to publishing original papers. Al-Khwarizmi’s work in elementary algebra, Kitab al-Mukhtar fi Nisab al-Jabr and al-Muqbela (“The Brief Book on Arithmetic by Completion and Balancing”).

• His pioneering work provided practical answers to land distribution, inheritance rules, and salary distribution.

• He also developed the concept of algorithm in mathematics, which is why some called it the “grandfather of computer science.”Al-Khwarizmi was one of the most famous scholars of the House of Wisdom, the Baghdad intellectual center.

The House of Wisdom was a center for the study of sciences, including mathematics, astronomy, medicine, chemistry, geography, and astrology.

Al-Khwarizmi’s Concise Book on Calculation by Completion and Balancing (The Compendium of Arithmetic by Completion and Balancing) was a pioneering work – providing practical answers to land distribution, inheritance rules and the distribution of salaries.

Al-Khwarizmi has a thesis that also supports the aeronautics and engineering behind the world’s fastest car.

al-Khwarizmi also compiled a set of astrological tables (the Zajij), based on a variety of Hindu and Greek sources. This work included a table of pockets, apparently for a radius of 150 units. Like his treatises on algebra and Indian and Arabic numerals, this astronomical work (or Andalusian review of it) has been translated into Latin.

Among his books:

– A book of algebra and interview.

– Book of drawing the quadrant of the globe.

– Book of working with the astrolabe.

– Countries calendar book.

– The Book of the Picture of the Earth, in which he presented the coordinates of places that are based on the geography of Ptolemy but with the improvement of the values ​​of the Mediterranean, Asia and Africa.

Manuscripts and papers on sundials and determining the direction of Mecca (Qibl).
