I've met a few people who've asked for something like this and, thanks to replacing my bloodstream with coffee, I've finally managed to get it all together.
A Comprehensive Guide To Earth Technology
Up to the Twenty-First Century
Compiled by Rebecca Crane
With PORTAL- and Promenade-specific Information from Tony Stark and Dr. Jacob Glaser
[ Rebecca has more or less written a book on every sort of common piece of technology she can think of, from toasters to indoor plumbing to headphones to computers to automatic doors. She's included an explanation of how electricity works, pictures and diagrams, and a section on technical jargon and slang. In addition, she's done her best to write it all in the simplest form possible. Included are excerpts (and, since this is an electronic document, links) to
Tony Stark's PORTAL guide and
Dr. Glaser's Promenade guide (properly cited, of course). ]
If anyone's interested, I'll also be teaching computer classes for any skill level at the Dalton Academy. I don't have an age limit for my class, so stop on by.
