Sillimanite:
- An aluminosilicate mineral
- A polymorph of both of kyanite and andalusite; same formula (Al2SiO5) but different structure
- Forms in high grade metamorphic rocks
- Named after Benjamin Silliman (1779-1864), a chemistry/geology professor #minerals
a poster with illustrations of 16 minerals eliminated in the first round of the 2025 mineral cup: chrysotile, okenite, jeremejevite, calcite, silver, leucite, sanidine, pollucite, azurite, wavellite, thortveitite, zunyite, topaz, ikaite, nontronite, and paddlewheelite. They have a large range of colours and shapes going from blue and green to yellow and red.

The professor has been fired and senior administrators removed from their post. No mention of this in the New York Times, The Free Press, The Atlantic or other outlets who drove the campus speech moral panic.

Hooray, dates for a Carnac region stone row! Fascinating excavation of a tomb, aligned standing stones & cooking pits at Le Plasker shows that the stone alignments were built piecemeal c.4680-4250 cal BC, and the tomb was built on the site of Mesolithic occupation: www.cambridge.org/core/journal...

Relatedly, if you haven't been in an archives you have no idea just how much historical material is not online, not even a digital record of it. An LLM cannot research data it doesn't have. It can't even extrapolate where to find that material.
