The Algorithm: From a 9th-Century Scholar to a Papal Warning
The word 'algorithm' derives from the Latinized name of 9th-century Persian mathematician Muhammad ibn Musa al-Khwarizmi.
The Origin of a Modern Term
Al-Khwarizmi authored The Compendious Book on Calculation by Completion and Balancing, which introduced algorithmic methods, popularized Hindu-Arabic numerals including zero, and laid the groundwork for algebra.
The term evolved through Latin algorismus, French algorisme, and English algorism, becoming conflated with 'arithmetic' before reaching its modern form.
The Journey to the West
Al-Khwarizmi's work was translated into Latin in the 12th century. The prefix 'al-' appears in other scientific terms that entered English during the Islamic Golden Age, such as alcohol and alkali.
What is an Algorithm?
An algorithm is defined as a well-defined set of instructions to accomplish a task. Algorithms have historically been used in business, surveying, navigation, and modern computing, including celestial navigation, Dijkstra's algorithm for shortest path, GPS, and lunar landings.
The Modern Concern
Pope Leo XIV, in his first encyclical, addressed potential dangers of artificial intelligence, mentioning 'algorithm' 19 times. He expressed concern about dehumanizing algorithms that reinforce single viewpoints.
