I came across Obsidian on my Mastodon timeline. Some time ago, the subject of “knowledge management” was a hot topic there.

Confession time: I have yet to find a satisfyingly regular and repeatable method for measuring neural canal diameters. A LOT of dinosaurian neural canals are not cylindrical but flare out on either end, like two trumpet bells set back-to-back.

Anita Cherry: Like Father Like Daughter  History was made in the winter of 1973 in the coal seams of Jenkins, Kentucky. Alongside Diana Baldwin, Anita Cherry became one of the first two women in the United States to work underground in a coal mine.

Appalachian Figures From Double Creek to Hindman James Still was born on July 16, 1906, in the Double Creek/Double Branch community near LaFayette, Alabama. After studies at Lincoln Memorial University (’29) and graduate work at Vanderbilt (M.A., 1930), he arrived at the Hindman Settlement School in the summer of 1931.

Appalachian Figures A voice from Knott County Verna Mae Slone was born in Knott County, Kentucky, on October 9, 1914, and died in Hindman on January 5, 2009.
