All elementary (and perhaps high) school material in one book?

I'm wondering if it would be possible (or perhaps if it already exists) to make a textbook aimed at adults that would cover all the material from all subjects for all the grades of elementary and high school (preferably some general high school, like grammar school), with materials explained in a way that's clear to adults (without needless overexaplanation and countless examples that are more suitable for children).

So it would be like some sort of encyclopedia.

This book would serve 2 purposes:

1) to help adults refresh their memories about the stuff they learned in school years and decades ago

2) to help non-native speakers of English re-learn things from school, this time in English, so that they get familiar with all the English terminology used in various sciences, as well as how to pronounce names of historic and literary figures in English, how to pronounce Latin in English way, etc... (Because, for example, a Polish person, who is well-educated, and learns English, will probably not know how to properly pronounce names like Archimedes or Achilles or Ezekiel in English even phrases like "homo sapiens" or "habeas corpus", because their English pronunciation is not transparent - and knowing classical Latin pronunciation doesn't help either, as English-speaking people don't pronounce with classical Latin pronunciation, but with traditional English pronunciation , so it's very hard to guess unless you learn it explicitly from some book. And that would impede the ability of non-native speakers of English to hold conversation about more "learned" topics, such as history, biology, law, etc... in English)
