if anyone else has papers or projects that use rix, please let me know! in open source, people open issues to tell you when things don't work (which is fine) but sometimes, getting positive feedback is nice as well :D

I'm a fan of design-based research and how it is deeply situated and also collaborative with (in this case) teachers and students. Seems like digital literacy is shifting every month, now, so we need more research like this into what students are actually doing. #PsychSciSky #AcademicSky #EduSky

With some help from Claude Code, I have the app I've always wanted:

elicitcausal lets you design a causal graph with your theoretical priors & preregister it. Then after you complete a study, you can upload your graph and get estimates of causal learning.

A classic black-and-white formal portrait of Dr. Alice Hamilton (1869–1970), pioneering American physician, toxicologist, and founder of occupational medicine in the United States. She is shown in a head-and-shoulders pose against a neutral studio background, gazing directly at the camera with a calm, intelligent, and resolute expression. Her dark hair is neatly parted and pulled back into a low bun, and she wears a high-necked dark blouse or dress with a simple brooch at the collar, embodying the quiet determination and professionalism that defined her groundbreaking career advocating for worker safety, researching industrial poisons, and becoming the first woman faculty member at Harvard Medical School.

A sepia-toned historical photograph from around 1893 showing an anatomy lecture or demonstration at the University of Michigan Medical School. In the center foreground, a young womanβ€”Alice Hamiltonβ€”stands at lectern, dressed in a long dark Victorian gown with high collar and long sleeves, addressing the class while gesturing toward a seated male demonstrator holding a small anatomical specimen. Surrounding her in tiered, curved wooden amphitheater seating are dozens of male students in formal 19th-century attire (suits, bow ties, mustaches), along with a few other women in long dresses seated among them. A bearded older man (likely the professor) sits nearby, and several attendees hold books or papers. The circular, tiered room with high walls and simple wooden benches creates a dramatic, intimate academic setting, capturing a rare moment of a woman participating actively in medical education during an era when female medical students were still exceptional.

Physician, research scientist & author Dr. Alice Hamilton was born #OTD in 1869.

She was:
+ The "mother of occupational medicine"
+ A pioneer in industrial toxicology
+ America's foremost authority on lead poisoning (c. 1916)
+ The first woman appointed to the faculty of Harvard, 1919

The nebula appears to have distinct regions that capture different phases of its evolution: an outer shell of gas that was blown off first and consists mostly of hydrogen, and an inner cloud with more structure that contains a mix of different gases. Both Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) show a distinctive dark lane running vertically through the middle of the nebula that defines its brain-like look of left and right hemispheres. Webb’s resolution shows that this lane could be related to an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions. Evidence for this is particularly notable at the top of the nebula in Webb’s image, where it looks like the inner gas is being ejected outward.

A classic black-and-white portrait photograph of Nobel Prize-winning physicist Maria Goeppert Mayer, taken in a classroom or lecture setting. She stands in front of a large chalkboard filled with handwritten nuclear physics equations, nuclear mass data, and element symbols (including notations like I¹²⁹, Cr⁡², and various alpha, beta, and gamma values). Goeppert Mayer has a thoughtful, focused expression as she gazes upward slightly, with her lips pursed in concentration. She wears a patterned dress with short-sleeved matching jacket with a geometric black-and-white design, a pearl necklace, and her hair styled in soft curls. In her hands, she holds a wooden slide rule.

Theoretical physicist Maria Goeppert Mayer died #OTD in 1972.

She shared the 1963 #Nobel Prize in Physics (w/Wigner & Jensen) "for their discoveries concerning nuclear shell structure." She was the second woman to win a Nobel in #physics. (Who was the first?)
