Language/Multiple-languages/Vocabulary/Geometry

This is a part of the Sci-Tech Index, a project for science and technology learners.

You can see the titles are a bit of weird. They are going to be read by machine and made use of by other means.

“Prerequisites” for non-English languages are to be generated through programs, so they are kept empty.

In progress.
