Al-Khwarizmi

Muhammad ibn Musa al-Khwarizmi, a Persian polymath born around 780 in Khwarazm, was a significant figure in the Islamic Golden Age, particularly in mathematics, astronomy, and geography. Appointed as the head of the House of Wisdom in Baghdad around 820 CE, he authored influential works, including "Al-Jabr," which systematically addressed linear and quadratic equations and is considered foundational to algebra. His contributions to mathematics included the introduction of the Hindu-Arabic numeral system to the Western world through his Latin-translated work "Algorithmo de Numero Indorum." This laid the groundwork for the term "algorithm."

Al-Khwarizmi also revised Ptolemy's geographical data, producing "Kitab surat al-ard," which improved the coordinates of various locations. His astronomical contributions included creating sine and cosine tables and developing methods for calculating the Earth's circumference. His works were pivotal in disseminating knowledge across Europe during the 12th century, influencing the development of mathematics in Western education.

Despite limited biographical details, al-Khwarizmi's legacy is profound, with his name giving rise to terms like "algebra" and "algorithm." His systematic approach to problem-solving and emphasis on practical applications in trade and surveying marked a significant advancement in mathematical thought. Al-Khwarizmi's influence persists, as his methodologies and concepts remain integral to modern mathematics.

> Al-Jabr (The Compendious Book on Calculation by Completion and Balancing, Arabic: الكتاب المختصر في حساب الجبر والمقابلة al-Kitāb al-mukhtaṣar fī ḥisāb al-jabr wal-muqābala) is a mathematical book written approximately 820 CE. [...] The term "algebra" is derived from the name of one of the basic operations with equations (al-jabr, meaning "restoration", referring to adding a number to both sides of the equation to consolidate or cancel terms) described in this book.

This is not correct.

المقابلة indicates two entities facing one another. Root is Q.B.L. from which we also get Qibla (that is direction of prayer). So it indicates the balancing of terms on each side of the equation.

الجبر is actually one of the names of God and it means forceful/irresistible compeller. In context of حساب (computation, reckoning) حساب الجبر then means a computation that is compelled (by mathematical logic).
