NEW: Our analysis found that from 2020 to 2025, the rate of deaths involving ectopic pregnancies nearly doubled compared with the previous six-year period. The uptick was steeper in states with abortion bans.

I did an OCR conversion of all my PDFs to make text files, built a semantic search index, and can just let my agents roam free to answer questions, fact-check, dig up interesting stories, quotes, etc. It takes a lot of the hard work out, as well as a lot of the human error. 2/2

Another big disconnect in the AI debate is academics/AIbros/AI pushers assuming they understand the methods, theories, debates, and philosophies of disciplines they are not trained in, and appear to have no desire to understand, but are POSITIVE gAI is necessary to those disciplines, nonetheless.

Another big disconnect in the AI debates is that it still seems like almost none of our humanities friends have used or even are aware of agentic AI.

Happy birthday to one of greatest mathematicians of all time Emmy Noether (1882-1935), here with her eponymous theorem, the backbone of modern physics. 🐡🧪👩🏼‍🔬🧮🎢 #histsci Noether’s theorem links any symmetry of a system with a conservation law. In my portrait, I chose to depict a young Emmy in front 🧵
My linocut portrait of Emmy Noether in front of a blackboard with diagrams and equations. Noether is printed in blue. She has her hair up and wears a pin-striped buttoned shirt with puffy sleeves, bow tie, tweed skirt with belt and is shown from waist up, turned slightly away from the viewer. The blackboard is green and shows a simple form of Noether’s equations at the top. On the left are three diagrams to represent translational symmetry (a frame of reference or 3 orthogonal axes and a straight diagonal arrow to a second frame of reference); rotational symmetry (a frame of reference and curved arrow to a second rotated frame of reference); and time symmetry (two simple clocks with an arrow between them and their hands at different places). On the right are the three associated conserved quantities: momentum (a p with arrow above it); angular momentum (an L with arrow above it); and energy (E).

In underfunded fields, people tend to do their own work. In overfunded fields, people pay others to do everything, including “their” research and writing. It’s not an accident that AI is an overfunded field that grew out of other overfunded fields.

How does Einstein access my Canvas?
You link your Canvas account once during setup. Einstein uses your credentials to log in, view assignments, and submit work on your behalf.

Will my professor know?
Einstein submits assignments from your account just like you would. The work is original and generated per-assignment — not copied from a database.
