What 𝚘 means
A fixed-width Latin o used in math and technical notation.
Monospace gives letters equal width, a style rooted in typewriter mechanics: each key moved paper by the same step. By 1999, science publishers used styled alphabets to distinguish variables; a proposal aimed to preserve those distinctions in plain text and search. The formula supplies the variable’s meaning.
