Fantastic read, thank you. I was never explained it this way, nor imagined it this way. I'll try keep an open mind and read more the surrounding content. That said, there is a syntactic language, which many equations use, and they seem to vary or be presented differently. The big S is one, the meaning of `|` which is probably not "OR" etc. I wish there would be a cheat sheet of sorts, but I feel it would be death by a thousand paper cuts with 300 standards of doing things(?)
