Grading and despairing… The following comes to mind, as I look at all the instances of the abomination that is the axis with two arrows:

Look, I’d be thrilled to get Even One arrow on sketches made by newly minted engineers showing where goddamn grid/project/local/even magnetic North is on the schweißig plan!
They all can do matrix algebra and use finite element software but don’t know how to sketch a merdique plan!

Thanks for a good laugh to end the work day!

C’mon, vectors should be in boldface. No arrows necessary.

lala: Sure, in printed textbooks.
However, I have yet to see a human embolden letters when writing by hand. Sadly, the widespread use of boldface in books has the downside that students now just omit arrow (and obviously do not/cannot denote boldface when they write by hand), so as a result they don’t distinguish vectors from scalars in their work, which is a very, very, VERY bad idea. -
The solution is not to accept hand-written work from students, but require them to use LaTeX for homework. Then take off for any vector written as a scalar.
