Brother of the Quill
A lot of learned points, but WTF are you talking about?A friend of mine is (or was) pretty good at French. He got me a copy of "Pythons on Pythons" (Monty Python members basically dissing each other) in Russian (which I can barely read anymore because the vocabulary is gone). He thought the title had two separate words, because he was completely unfamiliar with cases. It kind of shocked me. Anyway, once can ask whether there was "standard" Latin (nothing like Oxford English Dictionary) or whether we are stuck with haughty ancient sophisticates who could read and write just making a lot up as they went along. With all the subjunctive rules (in ancient Greek as well, which lacks punctuation and therefore requires all kinds of weird connector words) and such, one wonders whether people actually talked like that. The grammar is clearly a compendium of what ancient authors used--you don't know whether it's standard or whether some clown was in a completely separate tree. Also, the literature spans many centuries, and things change in that time (as English did).
To understand sciences like biology you need a lot of knowledge of in-jokes (Gary Larson, the "Far Side" cartoonist now retired, has a "sucking louse" named after him with his name Latinized, and many genes are named after what the fruit flies look like) as well as Latin and Greek, and for physics and engineering you need mathematics. High mathematics is very abstract, and most scientists can't do it. I have a book on the interface between mathematics and mathematical physics, which makes the claim it is a bridge between the mathematics mathematicians do and the mathematics mathematical physicists do, which are to an extent mutually unintelligible. I recall a math professor saying "you don't know what it is"--meaning it's mathematically unsupported--when physicists do integrals. In other words, "nobody talks like that", like what the mathematician does. In the preface to his books on quantum field theory, Steve Weinberg of noble prize fame claims the mathematics in it is "deplorable".
