This is ugly work in some respects, but it has to be done. Feedback is always requested on the assignments summarized here. Keep in mind that the presence or absense of a category is no judgement on the category itself, but simply a guess (as all of this is a guess) as to the sheer volume of entries a field is likely to eventually contain. That's why there's a "Pets" category that isn't under "Zoology," even though all animate pets (and rocks don't count, nor potted plants) could be considered Zoology.
I've bent science a hair when a category is in fact popular culture. Going back to the Pets category, well, yeah, I know that rabbits are lagomorphs, not rodents--but most people consider them rodents when they keep them as pets. Unless you're a zoologist, the whole business of rodents vs. lagomorphs is just hare-splitting anyway.
Now, if you're an expert in a field which has no defined subcategories yet, message me and let me know if you'd be interested in dividing out a category into subcategories. None of us here have a clue about Botany, for example (we're all silicon geeks here) and eventually this all has to be done.
The categories are actually stored in a database, and this document is a massaged output report.
