Algorithm
The word "algorithm" itself derives from the 9th century mathematician Muḥammad ibn Mūsā al-Khwārizmī, Latinized "Algoritmi". A partial formalization of what would become the modern concept of algorithm began with attempts to solve the Entscheidungsproblem (decision problem) posed by David Hilbert in 1928. Later formalizations were framed as attempts to define "effective calculability" or "effective method". Those formalizations included the Gödel–Herbrand–Kleene recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's Formulation 1 of 1936, and Alan Turing's Turing machines of 1936–37 and 1939.
Poetry analysis
The words "poem" and "poetry" derive from the Greek "poiēma" (to make) and "poieo" (to create). That is, a poem is a "made thing": a creation; an artifact. One might think of a poem as, in the words of William Carlos Williams, a "machine made of words". Machines produce some effect, or do some work. They do whatever they are designed to do. The work done by this "machine made of words" is the effect it produces in the reader's mind. A reader analyzing a poem is akin to a mechanic taking apart a machine in order to figure out how it works.
