• [[2022-08-28]] was productive but it ended with some deflation as I realized just how much there is still to do on [[agora pkg chapter]] and [[go/agora doc]] :)
  • sync is not solved, did the sync to [[agora doc]] by hand just now -- it keeps links but footnotes aren't really in the doc, there's some formatting issues.
  • there is just a lot to be edited/written yet.
  • there's duplication.
  • I need to be able to read end-to-end and not think "this section is completely crap/redundant" more than, say, once -- this evening ideally :)
• [[29]]
  • [[drishti]]
  • think of [[focus]], stay on target :)
• [[work]]
  • might take half a day?

• [[French Revolution]]

  • Listening: [[Revolutionary Left Radio: The French Revolution]]
  • Claim: [[The French Revolution has historical significance to revolutionary socialism today]]

• [[Wet-bulb temperature]]

• [[2022 Pakistan floods]]

• [[Bones]] are a source of [[calcium]] [[phosphate]], and so boiling and crushing bones and putting them into the [[land]] can be used to revitalize [[soil]]. Treating the bonemeal with sulphuric acid makes the calcium phosphate even more available to growing plants. [[Potassium]] can be had from a [[potash]] made of [[wood]] [[ash]], though it can also be found in minerals within [[rocks]].
• Excess [[food]] [[production]] and [[preservation]] is needed to give large [[groups]] of people [[time]] to [[think]].
• [[Enzymes]] are only active at particular [[temperature]], [[pH]], and [[salinity]] ranges.
  • A simple method to preserve [[food]] is to [[dry]] it.
    • When [[grain]] is harvested, it needs to be dried before it is stored.
      • High [[sugar]] content changes [[water]] activity by drawing water out of microbial [[cells]]. collapsed:: true
        • [[Sugar]] can be extracted from sugar beets by moving [[water]] through the [[beet]], taking that water, and drying it to expose the crystals from the beet.
      • High [[salt]] content changes [[water]] activity by drawing water out of cells and inhibiting microbial [[growth]]. collapsed:: true
        • 180g [[salt]]/liter [[water]] will act as a [[brine]] for [[meat]].
      • [[Acid]] is used to preserve food through things like [[vinegar]].
      • Kimchi, sauerkraut, and miso all use [[salt]] to draw out [[water]], and then salt-resistant [[bacteria]] to [[grow]] and produce [[acid]].
