The orthography of Greek math and science

The centerpiece of this package is the GreekSciOrthography, a concrete subtype of the abstract GreekOrthography type (from the PolytonicGreek package).

Characters

To the familiar alphabetic character set of the LiteraryGreekOrthography type, GreekSciOrthography adds:

• astronomical symbols for planets and zodiac signs that commonly appear in astronomical texts

GreekScientificOrthography.astro()

"🜚︎☽︎☿♀♂♃♄♈︎♉︎♊︎♋︎♌︎♍︎♎︎♏︎♐︎♑︎♒︎♓︎"

• the non-alphabetic characters used to write numeric values in Greek mathematical and scientific texts

GreekScientificOrthography.numeric()

"ʹ″ϛϙϡΜ𐅵𐅷𐅸^Ο"

Token types

In addition to recognizing lexical and punctuation tokens, a GreekSciOrthography can tokenize text into astronomical symbols, numeric tokens in the Milesian notational system, and labels for figures in mathematical texts.

 AstronomicalSymbol

Astronomical symbols are represented by single Unicode codepoints such as 🜚︎, “sol”.

In contrast to the other token types, the syntax of numeric values and mathematical figure labels is case-sensitive.

Integer values in the Milesian notational system are written using 27 alphabetic or archaic alphabetic characters, followed by the numeric marker ‘ʹ’ (Unicode x0374). (See full documentation in a guide to writing numbers.) A comma separates digits for ones, tens and hundreds (to the right of the comma) from digits for thousands (left of the commma). Μʹ is the value for “myriad,” 10,000. μ is the digit for 40.

Mathematical figure labels are defined as strings of upper-case purely alphabetic characters, without any breathing or accents. The string Ἡ is a lexical token (the nominative feminine singular of the article, in upper case), while Η is a figure label, “eta”.
