Historian friend was reading a civil war era letter in an archive, the letter said “In this envelope I include my smallpox scabs” and sure enough there they were. Had to call CDC for a hazmat team.

Got an email from a Catholic parish announcing that they've partnered with an organization to provide free will-writing services for community members. Would've been funny if they announced it on Ash Wednesday.

Story time: In my PhD oral qualifying exam, one of my committee members asked me what the Shine Dalgarno sequence was. My answer, paraphrased, was: "It's a genetic recognition sequence. I don't remember whether it's for transcription or translation, so I'm not sure if it's on the DNA or RNA.

Saying a version of "I don't know" and then outlining the steps you would take *to* know is a nearly-universal requirement for passing your qualifying exams as a PhD student. It was also a requirement for getting hired as a Supplemental Instructor when/where I was an undergrad.

an idea's been rolling around in my head about how what we lose with assuming everyone wants "answers" & not search results is similar to what we lose when "route" is the only kind of map we encounter I won't get the academic terms right, but it's some version of skipping an essential abstraction

I am losing my mind. Chat isn’t a search engine. this isn’t normal. framing it as normative is slimy. Tone, vibes all bad.

Mathematician Marie-Louise Dubreil-Jacotin, known for her work in both fluid mechanics and abstract algebra, was born #OTD in 1905. She was the first woman to hold a full professorship in Mathematics in France. 🧪 ⚛️ 👩‍🔬 🧮 Image: MacTutor History of Mathematics Archive

A black and white photo of Marie-Louise Dubreil-Jacotin. She is shown from the side, and from the shoulders up, with her head turned to her left to face the camera. She has short dark hair curled up at the bottom, and appears to be wearing a gown than sits low on her shoulders. She is smiling, not looking directly at the camera but slightly below and to the left. A necklace is just visible, but the photo is low resolution so it is hard to make out details.

Danville had a tough 20th century of manufacturing loss. Dr. Miller has been practicing cardiology there since the 70s, and when I interviewed him a decade and change ago, his stance was that a heart-healthy city walks, and walking should be part of its recovery. Fantastic guy.

This Danville, VA city council candidate made a very dramatic video about sidewalks and public safety, and I love it and him. Worrying about a possible milkshake duck situation, I looked at his FB page, but he seems ok. Juneteenth celebrations, community outreach, Methodists. A solid old gent.
