If you're a curious type: maybe an academic, maybe a hacker, or a student—then PolyMath is for you
Polymath is a new markup language (like Markdown, LaTeX, or HTML) specialized in aesthetically presenting a wide
variety of information: text, mathematics, code, photos, videos, you name it
It comes equipped with powerful tools to integrate the language in your writing, development, and production
environments
The language is currently expected to release in late 2021
