I made a history timeline to learn what events happened around the same time

It would be great to make one for all the innovations and discoveries be its technical, mathematical, etc etc. Also maybe creating some linkage or graph sort of thing for showing the discovery or invention which led or built foundation for another discovery in later years (umm not sure, might be too complex... just an idea)

I’ve been thinking about building precisely that sort of tech tree for a while, then extending it forwards in time to see if we can guess at how to work backwards from hypothetical technologies to where we are or if we can see obvious gaps
