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).

Analyzing scientists' biographies during the baby boom, we find that mothers have a unique life cycle pattern of productivity. Children reduce the productivity of mothers but not fathers, with important implications for promotions and participation. buff.ly/39WbYRH

This, from my colleague
Brent Neiman says it all.

Trump admin used the results from his paper to justify tariff rates. Except they used the completely wrong number.

A personal anecdote: a Syrian surgeon amputated my step-Dad's leg last Christmas, assisted by a Syrian surgeon. There's an enormous shortage of doctors in our rural town, long wait times, even with life-threatening disease. Zero capacity. And I did not see a single German-born physician.

Effects on US innovation were disastrous. After the quotas US scientists patented 30% less in the pre-quota fields of ESE-based scientists relative to other fields. Research with @mulysan.bsky.social & Sahar Parsa: www.dropbox.com/scl/fi/h80j9...

Eastern & Southern Europeans (ESE) had the same response to the 1920s quotas act. Intended to limit low-skilled immigration to the US the quotas exempted university scientists and students. Still, the US lost an estimated 122 ESE-born professors & 670 scientists who would have come as students 2/n

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!

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.

"The feeling of not being wanted in that country" is an issue not only in Germany but also in the US, historically and today. In "Immigration and Innovation. Lessons from the Quota Act" we find that students, who were exempted, did not come to the US after the quotas if their countries were targeted

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?
