Jeffrey Lin@jeffrlin.bsky.social · last mo.On February 14, 1876, Bell & Gray each filed for a telephone patent. Such collisions were once routine — up to 1 in 20 patents triggered an "patent interference." Over the next 150 years, that rate fell by more than 98%. In a new paper, we explain why — and what it might cost.
Managed to image M51 and M13 from rural Ohio last night. Great conditions until the clouds rolled in!

I really enjoyed spending the last 30 minutes figuring out that in order to submit my paper to an Elsevier journal, the MS can be pdf, but the separate title page cannot be a pdf, but must be either a Word file or sent to them by post as cuneiform tablets.
Really awesome that schools and summer camps frequently have special dress-up “theme” days for my 11 year old. Nothing better than waking up and learning it’s “wacky Wednesday” and she needs to dress up as her favorite holiday. Really keeps me on my toes. Grateful.
🧵1/ The half-life of a grudge. Britain crushed the 1857 revolt in northern India with mass reprisals centered on Lucknow. For decades after, districts closer to that violence vaccinated their children less against smallpox and the effect faded as the generation that lived through 1857 died off.

In terms of its role in Europe's development, the Dominican order is perhaps most known for its part in the inquisition. However, it also had a more benevolent impact on regime change and the development of human capital 1/N
I'm not the best lip-reader, but I believe what she is saying is "I disagree with the offsides call" in Croatian.
🧵 1/ The most famous party trick in AI: take word vectors and compute "king − man + woman." You (often) get queen — evidence the model learned gender as a direction in space. Could you pull that off using nothing but the titles of books printed in Europe, 1450–1650?
Want a politically (and economically) productive investment? Absolutely massive universities in low population states. Land grant universities x1000
mtsw@mtsw.bsky.social · last mo.What no one ever considers is: What if "investing in Red America" is just politically hopeless? Can we maybe, for once, invest in blue America instead?

A couple things I learned doing research this week... The Thirty Years' War (1618–48) didn't simply shrink German printing — it redrew the map. After imperial forces sacked Magdeburg in 1631, the city's presses went nearly silent. Neutral Hamburg's boomed. The two cities traded places.

Big shout out to ScholarOne Manuscripts for finding a way to make doing referee reports even more annoying. I've had to reset my password two times now and do a separate registration process with ORCID all just for the privilege of downloading the manuscript that I will do a report on for free.
