I went down the rabbit hole of the #chemistry of historic #copper ore processing in smelters. Found this very detailed explanation by a rather sassy author who provided incredible details on the subject.

Meghalaya - Wikipedia
https://en.wikipedia.org/wiki/Meghalaya
The importance of #Meghalaya is its possible role in human history via domestication of #rice. One of the competing theories for the origin of rice comes from Ian Glover, who states, "India is the center of greatest diversity of domesticated rice with over 20,000 identified species and #NortheastIndia is the most favorable single area of the origin of domesticated rice."[18] The limited #archaeology done in the hills of Meghalaya suggest human settlement since ancient times.[19]

Victor Goldschmidt (1888–1947) is often considered the ‘father of geochemistry’. One of Goldschmidt’s achievements was to begin to systematize the behaviour of the chemical elements in an Earth Sciences context via his classification of them according to their preferred host phases on silicate Earth (Lithophile, siderophile, chalcophile and atmophile). This is still one of the most widespread geochemical classifications of the elements today and was an important step in terms of bringing the principles of chemistry to bear on the study of the Earth.

Some Scientists Believe the Universe Is Conscious - Sounds like a bad trip ... but what if it's true?
https://www.reddit.com/r/Futurology/comments/nx62c7/some_scientists_believe_the_universe_is_conscious/

“Although I think that life may be the result of an accident, I do not think that of consciousness. Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.”
~ Erwin Schrödinger
