Has anyone encountered an interesting hand-lettered or type-set "Q.E.D." before? It's used to mark the end of a mathematical proof. The contemporary digital version is, unfortunately, the "tombstone," a simple black square (yawn).

Thanks!

Dear all,

Since years, Arabic fonts used in Mathematics, Physics and Chemistry for elementary - preparatory school's level are used locally in Arab countries.

However, Dr. Lazrak and his team (UCAM, Morocco) presented some interesting reviews for different used systems through the Arab World and, I think, they applied it to LaTex.

Currently, with STIX fonts arriving to good maturity, I think it is time to work on this project and we, @ Aratypo, welcome any person who would like to share with us thoughts and efforts in order to realize this font.

Thanking you in advance.

Hello old ƒriends.

A casual conversation in which I made a couple of claims has resulted in a search for evidence to back those claims, and, though I have seen this with my own eyes, I cannot find what I am thinking of. Or rather, what I am thinking oƒ.

My query is threeƒold:

1. What is the proper name of ƒ? Windows Character Map calls it "Latin Small Letter F With Hook." That sounds donkey, but I can't come up with a better name. All I can think of is, "You know, the eff you use when you're writing a function in math."

2. When (90s?) and why (ease of typing? sorting?) did the practice of prefacing or appending folder names with ƒ on Mac OS come into practice, and how widespread was this practice? The latter question leads me to 3.

For a long time I have been typesetting mathematics with LaTeX, which of course works very well. For a while I have contemplated the prospect of typesetting mathematics via letterpress, namely with Monotype's 4-line system.
