These are all perfect as God intended, you see, you must be able to ''feel'' a mathematical notation with your mind, if you wish to be a true beholder of the art and craft of mathematics.

When I look at that notation for example, and when I write it down, it is a Godly and divine expression of art, but also a sensation of the notations meaning; in this case a derivative.

I would have to say thats what a derivative feels like. It is something a like zzzZZZPPPHOOO, a backwards circular woosh of some sort, finishing off the top.

The calculus swoosh is also fantastic. It feels something like this: VVVFFFFFFFEEEEEEEEEEEEECH, from one side to the other. When you write it down in true sensation of what its supposed to feel like, complementing its rational nature, you have composed a fine work of art and craft.

most probability and statistics notation is pretty retarded, especially "random" "variables".

Not for the actual concept but because of its abuse by CS fags. When a CS fag says O(n) they could be trying to say three completely different things.

would have been way more useful if they explained right away that it’s just a compact notation for “the third parameter of f() which we substitute with y’ , but only after derivation“
