Algorithm
The word 'algorithm' has its roots in Latinizing the name of Muhammad ibn Musa al-Khwarizmi in a first step to "algorismus". Al-Khwārizmī (, , c. 780–850) was a Persian mathematician, astronomer, geographer, and scholar in the House of Wisdom in Baghdad, whose name means 'the native of Khwarezm', a region that was part of Greater Iran and is now in Uzbekistan.
History of engineering
The term "engineering" itself has a much more recent etymology, deriving from the word "engineer", which itself dates back to 1325,
when an "engine’er" (literally, one who operates an "engine") originally referred to "a constructor of military engines." In this context, now obsolete, an "engine" referred to a military machine, "i. e.", a mechanical contraption used in war (for example, a catapult). The word "engine" itself is of even older origin, ultimately deriving from the Latin "ingenium" (c. 1250), meaning "innate quality, especially mental power, hence a clever invention."
