@ben_lings points out that I misread the dates (June -> July): the vaccination was done a month later. Still extremely impressive, but not at the same level. https://twitter.com/ben_lings/status/1224950047978262530 … I'd delete the original, but at this point it seems better to put this correction here.Prikaži ovu nitHvala.

In some sense the climate and energy community are engaged in their own civilization-scale
@longnow project: they're building models of the world 50, 100, even hundreds of years in the future; they're building a culture around that understanding; and they're taking action.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

The Central England Temperature series, from 1659 to today: https://en.wikipedia.org/wiki/Central_England_temperature … Compiled after-the-fact in the 1950s by Gordon Manley. (Also fun to read about are modern Stevenson Screens, designed for more reliable records: https://en.wikipedia.org/wiki/Stevenson_screen … )

LIGO took ~50 years. I cannot conceive of how you would set out, circa 1970, to achieve a strain sensitivity of 1 part in 10^22. But they did it.https://twitter.com/michael_nielsen/status/1130555588524384256 …

Interesting to divide responses into two types: strongly goal driven (eg the Gaudi Cathedral, Shinto Shrines, Framingham) versus more undirected / local (eg population growth, University foundation). Both very interesting, in very different ways.

Curious: are there examples of goals / projects that are easy, almost trivial to do over a very long period, say 100 years (or 1,000 years), but impossible over 10 years? Eg a scientific question that's trivial to answer over the longer time frame, but imposs over the shorter?

Ditto the famous Keeling experiment carried out measuring CO2 (and now other gases) on Mauna Loa since 1958: https://en.wikipedia.org/wiki/Keeling_Curve … Now run by Charles David Keeling's son Ralph!

... some air from 1972, to see what was happening then". And they can just give it to them. Incredible!

I am lacking the right keyword, but I went to a great talk once where someone talked about an _air archive_. Basically, they went outside every day, starting in the 1960s, and bottled up some air, for decades(!) Then, after the fact, people can say "Oh, I want to analyze...

Not quite a project, but Kongo Gumi was a construction company that ran for nearly 1,500 years, before (very sadly, IMO) being acquired in 2006: https://en.wikipedia.org/wiki/Kong%C5%8D_Gumi …

The Pitch Drop Experiment, to demonstrate that pitch is really a liquid which flows, is closing in on 100 years: https://en.wikipedia.org/wiki/Pitch_drop_experiment … (I used to walk past this every day - my office was in the same building!)
