A set of rules for solving a problem. No, the first anonyponymous person in the book is not Al Gore. When a word begins with al-, there’s a good chance it comes from Arabic. This is true with alchemy, almanac, alcove, alcohol (ironically), and algorithm, named for Muhammad ibn Musa al-Khwarizmi, or, as his Latin translators called him, Algorismus. In the early ninth century Baghdad was fast becoming the world’s most important center of trade and learning, and while engaged at its illustrious House of Wisdom, al-Khwarizmi produced his most famous work, The Book of Restoring and Balancing. In it, al-Khwarizmi explained how to solve complex mathematical equations by a method called al-jabr, Arabic for “reunion of broken parts,” which came rendered in Latin as “algebra.” (See about those al- words?) On an even more basic level, al-Khwarizmi was instrumental in the spread of Arabic numerals. Not that he invented them, nor did anyArab; the symbols originated on the Indian subcontinent in the centuries leading up to Christ.
