In no particular order, these things came to mind as things I’m interested in learning more about.

Early Astronomers

Early Inventors

Gutenberg (of Gutenberg Press fame)

Trade Routes and their impact on world history

Weather Stations and weather tracking around the world

Family life around the world

Cartography, and the history of map making

So, I’m off to the library soon, I hope. This is one of those things that come to mind when someone asks, “but how will they learn everything they need to know?” There’s so much that all of us learned in school that we have forgotten. Tis far better to learn anything when the knowledge is contextual and desired.
