When I got tenure, I decided to use it start a new research agenda, studying US science in the 20th century, how it became dominant, what held it back, and what we can do better. Here's the first pub (with Scott Kim).

Some Germans want Syrians to return home - unless they are doctors. That won't work: "If my family and friends aren't allowed to stay, then I don't want to either." 1/n wapo.st/3DDxUYd

6,000 Syrians work as doctors in Germany. Some weigh whether to stay or go.
Syrian doctors have established themselves in Germany, filling critical health-care gaps. But Assad’s fall and anti-migrant sentiment have some torn.

Dunno what this says about me, but I saw "Moby Dick" at the Met last night and absolutely loved it, down to the "squarely undulating minor-key references to Philip Glass, John Adams and Britten..." Go see it if you can! www.nytimes.com/2025/03/04/a...

When German Alexander rammed his car into a group of people in Mannheim on Monday, killing two, wounding 25, he was stopped by Afzal from Pakistan. It's funny how we only hear names and place of birth when they match our fear and prejudice.

ESA now puts the probability of Earth impact at 1.8%, NASA (miraculously not dismantled yet by Musk and Trump) at 1.9%. NASA data suggest a yield of roughly 8MT TNT equiv. Big, but Tsar Bomba was bigger 🤓 tl;dr: it's very unlikely to hit. And there's zero chance we'll be wiped out as a species.

I'm shocked by the implied decline in inequality between 1913 and 1958. Did WWI, the Great Depression, and WWII disproportionately destroy top wealth? Using the same measures for 1913 and the rest of the graph, 1913 may look as bad as today. So what happened in the first half of the 20th century?
