Why Grist Mills?

  Roots of Progress is an interesting effort I follow.  This particular post  roused my usual contrarian reaction, but also triggered a question, specifically this:

" you should take into account that some types of labor were automated very early on, via wind and water mills"

My question is why?  And who?

ChatGpt says, when asked how different civilizations ground their grain:

Ancient Egyptians: The ancient Egyptians used a hand-powered quern to grind their grains. The quern consisted of two flat stones, one placed on top of the other. The top stone was rotated back and forth to grind the grain into flour.
Ancient Greeks and Romans: The ancient Greeks and Romans used a rotary mill to grind their grains. The mill consisted of a circular stone wheel with a handle on one side. The grain was poured into a hole in the center of the wheel and was ground between the wheel and a stationary stone.
Native Americans: Native Americans used a mortar and pestle to grind their grains. The mortar was a bowl-shaped stone, and the pestle was a long, cylindrical stone used to crush the grain.
Chinese: The Chinese used a stone mill to grind their grains. The mill consisted of two horizontal stones with a vertical stone in the center. The grain was poured into a hole in the center stone and was ground between the stones.
Mesoamericans: The Mesoamericans used a metate to grind their grains. The metate was a flat stone slab, and the grain was ground using a handheld grinding stone called a mano.
Overall, each civilization developed methods that were suited to their particular needs and resources.

Based on skimpy research by google, it seems there's a transition from rubbing two stones together, to a rotary grinder hand powered and then to the water/wind driven grist mills. 

Did women initiate these inventions?

Trump, the Last Gasp of the Patriarchy?

 There was a sudden burst of women running and winning as Republicans in 2020. Some of them were and are supporters of the former president, but I've the optimistic suggestion: future Republican presidents will appoint significantly more women judges and women administrators--indeed I predict the pattern will be much closer to that of President Obama, if not President Biden.

Sounds Like Advantage to Females?

 Steve Kelman reports on research in Federal Computer Week--"soft skills" help team performance. To me it reads as if teams will work better if they have at least one stereotypical woman.

Hidden Factors in Economic History

 I'm intrigued by the idea that some hidden factors account for economic gains:

  • The invention of eyeglasses. That must have significantly improved the capabilities of a segment of the population 
  • The change from women as housewives to women as teachers to women as professionals.  Those changes raised the average intelligence of the (paid) workface, while lowering the average for the teaching profession.
  • The opening of "virgin land"--meaning the exploitation of fertility accumulated over years
  • The invention of the container ship.  (Good book on that.)
[Updated 1: The invention of writing of course was important, as were the inventions of libraries, and public libraries, and lenses which were prerequisite for glasses and then Ben Franklin's bifocals.

Updated 2:  The adoption of uniform time zones in the 1880s]

Women Advance? Some Evidence

It's interesting to follow the posts on the FSA Facebook Group for a number of reasons.

Sometimes posters in the group ask for help on various issues, questions of policy, software, approaches to handling service during the pandemic. Sometimes it's just sharing news, funny stories, etc.

In the last week there was a work issue which seems to have been solved by some software developed by a county employee, which a number of people asked for.  Back in the day that sort of thing happened as well.  A couple difference from 30-40 years ago:

  •  the existence of the Facebook group.  I don't think we had a formal sharing site before the SCOAP QandA's in the late 80's and Jeff Kerby's BBS around 1990 or so. There's more lateral communication these days as opposed to running things up and down the ladder of the hierarchy.
  • the gender of the person creating the solution. In the old days the creators tended to be males (I'm thinking of doing programs for programmable calculators around 1980 and queries for the System/36.  I might be wrong on this--it might be I just noticed or remember the men more and/or the female creators were operating in a more informal environment.
I think both differences are good.

Women, Cows, and Hens

Just skimmed this summary of research on economic history.  A couple paragraphs:
Given the obviously crucial role of endogeneity issues in this debate, we carefully consider the causal nature of the relationship. More specifically, we exploit relatively exogenous variation of (migration adjusted) lactose tolerance and pasture suitability as instrumental variables for female autonomy.
The idea is that a high lactose tolerance increased the demand for dairy farming, whereas similarly, a high share of land suitable for pasture farming allowed more supply. In dairy farming, women traditionally had a strong role; this allowed them to participate substantially in income generation during the late medieval and early modern period (Voigtländer and Voth, 2013).
My translation: women do better with dairy cows than plowing ground for grain, and if women do better, the overall economy does better.

A similar logic could apply to chickens.  You don't need a lot of strength to manage a flock of hens.  The one advantage dairy has over chickens is it's easier to store dairy products--cheese specifically, than it is eggs.

I suspect this may be over-simplified. I vaguely remember that the development of plows which could handle the soils of northwest Europe, soils which were heavier than the soils of southern Europe, was a big deal, at least in history as it was taught 60 years ago.
