comment Why do mathematicians use single-letter variables?
@Harry Altman Quark was not invented by physicists, but was taken by Murray Gell-Mann from James Joyce's Finnegan's Wake, in the phrase "Three quarks for Muster Mark!".

comment What came first, the $\forall$ or the $\exists$?
Isn't E backwards the same as E upside-down regardless of the horizontal symmetry? I prefer to think of both as upside-down letters, as this is how they would have been produced on a printing press. You cannot make any letter backwards with the movable type, but you can place letters upside-down.

comment Multiple integral differential notation
Thanks for your answer, I know that the $d^3 x$ stands for the volume in all these various coordinate systems, I just chose dimension 3 as an example really. From your answer I can see that you are saying $d^n x$ has nothing to do with higher-order differentials. But I would be interested to know where this comes from and who originally suggested this notation as it is easy to confuse with a higher-order differential.
