FYI Science Policy News: More U.S.-trained physicists are leaving the country, an exodus that adds to fears of a U.S. "brain drain" www.aip.org/fyi/physics-... a near-doubling of non-US citizens left the US after receiving their PhD, around 29%, in 2025 @aip.bsky.social
Physics PhDs Are Leaving the US at a Record-high Rate
The exodus of non-US citizens has “certainly” been influenced by science funding and visa policy changes under Trump, a new AIP report says.

When he was at Fordham University Donald Trump wrote a thesis, “An account of Codmon's Metrical Paraphrase of Scripture History, an illuminated Manuscript of the Tenth Century” in which he postulated it was written about or soon after the year 1000. #academicsky

Time for one historical scientific art post: Sarracenia rubra, or the sweet pitcher plant, is a carnivorous perennial wildflower native to the SE U.S. From my copy of North American Wild Flowers by naturalist & botanical artist Mary Vaux Walcott, published by the Smithsonian Institution in 1925. 🐡
No time for a morning 🧵 so here’s a thread on physicist Max Born I did yesterday evening. His Jan, 1916 paper below was a “very” early exposition. Einstein published his consolidated review of the theory in Annalen der Physik afterwards on March 20, 1916. 🧵 ends with a twist. #physics ⚛️ 🧪

One of my favorite owls depicted on a hand-colored copperplate engraving from “Bilderbuch für Kinder”, a German children’s encyclopedia published between 1790 and 1810 by Friedrich Justin Bertuch. Coin for scale. 🦉 🪶
The Linnean Society of London@linneansociety.bsky.social · yesterdayOwl Day or is it best scowl day? We especially love this illustration because it has owls but also so much more! From Alexander Wilson’s American Ornithology, titled “Great Horned Owl, Barn Owl, Meadow Mouse, Red Bat, Small-headed Flycatcher, Hawk Owl”. And how cute is that bat?!
And also these grand snowy owls sketched by John Gould, lithographed and painted by Edward Lear. From The Birds of Europe (published between 1832 and 1837). #OwlDay

An article by Albert Einstein he wrote for the bicentenary of Newtons death ICYMI (I don’t think thread posts are seen). For those unaware, Einstein was a German physicist who wrote some groundbreaking work that led to a greater understanding of the universe. Same with Newton, but he was English. 👇

An article in my personal library by German physicist Lise Meitner that may (or may not) interest the history of science and/or women in STEM folks. Her research during this period clarified transitions between alpha & beta particles, paving the way her later work on nuclear fission. ⚛️

Anything of interest happen here today while I was enjoying the outdoors?
I use money to provide scale on much of the stuff I post from my personal library. This one was fun: Grant crushing Lee (again), Lincoln pinning him down.

bookswain.bsky.social@bookswain.bsky.social · 2d agoSince books are my hobby, sometimes I acquire a title because of its scarcity or historical significance, not because I agree with the subject. This is one, ‘La Cause Perdue’, a French translation published in New Orleans in 1867 of Edward Pollard’s “The Lost Cause.” Coin for scale 📚💙 (1/n)
