would make Nostradamus look like an idiot.

The one invention at this point that I’d have to actually build is the printing press a few hundred years early. So my book can be distributed (Id have to carve linocut blocks for the essential illustrations to be printed. Fortunately I’m an artist). If the cruder and older ideas in my encyclopedia were to be proven correct,(eg. I could make a compass, which they’d never seen at that point. I could tell them about the gunpowder the Chinese were using and then make the first cannons) the notoriety of the book could grow enough to get centuries of people smarter than I am to study it.

In their own lifetimes they could build off of each other and develop soooo much faster.

Then more things would make sense to them from my book as they moved forward and built up. The later chapters and drawings would make zero sense at first, but over the accelerated centuries of development the world’s greatest minds would crack more and more of what would appear to be a code to them that is actually the clearest Id be able to explain things.

Basically Nothing was known in Europe at that time (much less here in America). Heliocentric theory was still 600 years away. I could draw the solar system. Explain gravity. Germ theory would change soooo much. Disinfecting would save countless lives. Glass can be shaped into lenses (eventually) and you’ll see the shape of these planets I’m talking about. The rings of that one I drew. With a microscope you’ll see this structure of cells…. that’s what life is made of.

Describe the scientific method 500 years early. Converting people to its use alone would be a revolution.

Yeah, I couldn’t build much in my lifetime. But I could write and draw info that would continue to blow minds for hundreds of years. I’d say 1000, but I expect their development to accelerate so much more quickly that it shouldn’t take nearly as long as it did in our timeline.
