Hi, English isn’t my mother tongue so I was asking myself that question since I first encounted a w/… Back then I was like: “What tf does ‘w slash’ stand for?” And when I found out I was like “How, why, and is it any intuitive?” But I never dared to ask that until now
If that annoys you, never get into advanced maths. There’s arbitrary symbols that make no sense like 3 dots in a triangle means therefore. An upside down capital A means for all.
I still use the three dots for therefore sometimes without really thinking about it. I never pursued work in maths or physics (I set and run industrial machines) but for some reason that one always stuck with me from school.
Good, this is what school is about
It finally worked!
I just use TF as i need it all the time for notes and stuff, but really wish I could use the 3 triangle dots, which I learned to use in logic. I wish the emoji picker (ctrl+period) could accept a searches for more symbols. On windows a search for the cucumber emoji works, but you can’t search for greek letters. sigh
But that’s a different use case. It’s math, not everyday written language.
Mathematicians didn’t want to write a conclusion paragraph to their proofs to say that that result proves what they wanted to show, so they just put “QED” at the end which is some Latin/Greek phrase to the effect.
Then they got too lazy to write that because they do proofs all the time, so they just put a box ∎ that means “so, basically yeah. there you have it.”
Q.E.D. is “quod erat demonstrandum”, meaning “thus, it has been demonstrated”.
