24 letters · names and where science uses them
Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.
Three sizes in one archive — from a sheet on the fridge to a poster on the wall.
Classical order, 24 letters. Usages follow standard practice in physics and mathematics.

Upsilon likewise means “plain u”, as opposed to a digraph that sounded the same.
So half the Greek letter names are pronunciation instructions baked into the name itself.
Why the numbers can be trusted.

If one fails, there is no file.
