Based on a HN comment, I made a page which proposes the hypothesis:
(Δ t-historic) = (Δ t-today)^(log 5/ log 2)
where the Δ t-historic is the time in decades from the invention of the printing press and Δ t-today is the time in decades from the opening of the ARPANET.
A collection of interesting correspondences is given, as well as some predictions, if this hypothesis is to be taken seriously.
The page has a small JS script for a calculator t-historic to t-today, so you can easily find new correspondences if you like the game. Please let me know in case.
UPDATE: There is now a very amusing python3 script by 4lhc, at this gist. It lets you write a year, recent or old, then it proposes two events, one from the old time and one from recent time. I played with it on my computer and it’s just cute!
[I had to install the wikipedia module and then the correct command is
wait a short moment and get the pair of events!]
