1. This round clay disc, looking a bit like a broken biscuit, is at #Moesgaard Museum near Aarhus in Denmark. It doesn't look like much. If you look carefully, you can see some circular depressions around its centre, and some linear depressions radiating out from them towards the edge of the disc. They look as though they have been made by a finger in wet clay. The diagram shows how the museum have recorded those lines and circles....
(Spoiler: you will be amazed by the interpretation)

“To cross the southern coast of England, west to east, is thus to travel forwards - and at breathtaking chronological speed - in a self-propelled time-machine. With every few hundred yards of eastward progress one passes through hundreds of thousands of years of geological time: a million years of history goes by with every couple of miles march.”
― Simon Winchester, The Map That Changed the World: William Smith and the Birth of Modern Geology
In 1793, William Smith, was a surveyor by trade and trained in mapping and geometry. He apprenticed under England’s master surveyor, and traveled all over England surveying for canals. Smith became an expert in England’s rocks noting that they, and the fossils they contained, occurred in vertical layering representing successively older rocks the deeper he dug, and that the fossils within changed the deeper he went. Smith realized that the same sequences of rock could be correlated over vast horizontal distances, indeed over the entirety of England, and could be used to trace the underpinning rock to facilitate mapping. His epiphany became the Principle of Faunal Succession and became the key to unlocking Deep Time.

Smith began traveling all across England while surveying for minerals, noting the rocks and fossils and began recording and mapping the rocks, choosing a different color for each rock type and estimating the extent and boundaries it covered. In 1815 he published his geological map which covered England, Wales, and part of Scotland and contained a stratigraphical analysis with the fossil index of each layer. It was the largest geological map of its time and contained a geological cross-section that revealed the 3D geometry of the rock beds.
Sadly, William Smith fell upon rough times, and it wasn’t until 1831 that he became widely recognized as the Father of English Geology and Stratigraphy, and he was bestowed with honorary degrees, titles, and a pension for the rest of his life. His beautiful map remains today as one of the greatest breakthroughs in Geology.

Question:
"Can you compare the lava production rate at fissure 3 to Fagradalsfjall's last summer?"
Answer:
"Based on our understanding of that eruption from the scientific literature (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021GL097125), the current Mauna Loa eruption has an effusion rate that is about 10x that of the 2021 Icelandic eruption."

Observations after being on #Mastodon for about a month:
- At least so far, there is a culture of friendliness. It's quite alluring and it should become standard both online and offline.
- We were made aware of how much the Twitter algorithm emphasized user outrage in order to increase engagement and increase revenue. Our feed is fascinating and helpful here.
- In addition to responding to toots, people often submit poetry, songs and thoughtful questions. #Twitter was never so enjoyable.
3 December 1942 | SS escorted around 400 Jewish prisoners of the Sonderkommando from Birkenau to Auschwitz I. They had been forced to dig up & burn ca. 107,000 corpses buried in mass graves. They were led into the gas chamber by crematorium I and killed.
The story of Sonderkommando is one of the darkest chapters of the history of Auschwitz.

Listen to our podcast about the fate of Sonderkommando prisoners.

My team at work just launched new research on the #TwitterMigration: We analyze which platforms are growing - especially #Mastodon, #Tumblr & #Post.
We look at which sites users are adding to their Twitter bios, posting to their friends about & downloading apps for.
