formúluna

Formúluna is a neologism used in speculative and fictional contexts to describe a formal system for encoding lunar data into mathematical expressions. It is not an established scientific framework, but a conceptual language intended to express relationships between time, lunar phase, and orbital geometry through formulas and functions.

Etymology: The term combines 'formula' and 'luna' (moon), with an accent on the first syllable to signal its stylized nature. The spelling formúluna appears in fictional glossaries and puzzle collections rather than in official scientific literature.

Concept and notation: A formúluna representation typically uses variables for time t, phase φ, and elongation ε, along with trigonometric and fractional components to capture periodicity. It may employ modular arithmetic to express cycles, and could include coordinate-like terms to reference selenographic positions. In practice, it is a portable shorthand rather than a fixed syntax.

History and usage: The term has appeared in science fiction writing, online puzzle communities, and scholastic thought experiments since the late 2010s. It is used to illustrate how lunar data might be structured in a compact formalism, or to frame challenges that involve predicting lunar events from abstract formulas.

Status: Formúluna remains a fictional or speculative construct rather than an endorsed scientific method. It serves as a mnemonic and teaching aid for lunar mathematics and as a device in speculative narratives.
