## Al-Khwarizmi: The Father of Algebra & The Grandfather of Computer Science
* Introduction to Al-Khwarizmi's dual legacy in mathematics and computing.

## Historical Context: The Golden Age
* Born c. 780 CE in Khwarizm.
* Scholar during the Islamic Golden Age under the Abbasid Caliphate.

## Bayt al-Hikmah (The House of Wisdom)
* Scholar at the intellectual center of Baghdad.
* Formalized the study of algebra in a library/academy setting.

## Al-Jabr: The Birth of Algebra
* Work: *Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala*.
* Shifted focus from geometry to abstract arithmetic.
* Origin of the word 'Algebra' from 'al-Jabr' (restoration).

## Applications of Algebra in the 9th Century
* Practical uses included:
    * Inheritance (primary application: 45 units)
    * Transactions (20 units)
    * Surveying (15 units)
    * Canals and Geometry (10 units each)

## Revolutionizing Numbers
* Introduced the Hindu-Arabic decimal positional system.
* Popularized the concept of Zero (*Sifr*) as a placeholder.

## Geography & Astronomy
* *Kitab Surat al-Ard*: Listed coordinates for 2,402 cities.
* *Zij al-Sindhind*: Created astronomical tables for sun/moon movements.

## The Origin of 'Algorithm'
* His name was Latinized to 'Algoritmi' in the 12th century.
* 'Algorithm' evolved from his methods of calculation to form the basis of modern programming.

## Impact on the West: Dixit Algorizmi
* Translated by scholars like Gerard of Cremona.
* 'Dixit Algorizmi' (So said Al-Khwarizmi) was a mark of mathematical authority in Europe.

## Conclusion: A Universal Legacy
* Unified Greek and Indian mathematics.
* Established the global 0-9 numeral system.
* Foundational influence on every modern algorithm.
