Al-Khwarizmi
Father of Algebra & Algorithms
Why They Changed Society
Al-Khwarizmi's contributions are woven into the fabric of modern civilization in ways most people never realize. His book 'Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala' gave us the word 'algebra' and established it as an independent discipline. The Latin translation of his name — Algoritmi — became the word 'algorithm,' the fundamental concept behind every computer program ever written. He introduced the Hindu-Arabic numeral system (0-9) to the Islamic world and Europe, replacing cumbersome Roman numerals and enabling modern mathematics, commerce, and science. Without his work, the scientific revolution, the digital age, and computational thinking as we know it would not exist.

Notable Quotes
“When I consider what people generally want in calculating, I found that it always is a number.
— Al-Jabr, c. 830
“That fondness for science, that affability and condescension which God shows to the learned, that promptitude with which he protects and supports them, has encouraged me to compose this short work.
— Preface to Al-Jabr
