Managed to image M51 and M13 from rural Ohio last night. Great conditions until the clouds rolled in!

The Swiss head coach is the most European looking person I’ve ever seen.

It is, once again, leaf blower season. As tradition dictates, a haiku… Blowers hum and wail, Thoughts drift like leaves in the gust— Workday blown away.

Unfortunately, a stunned Paris is how they all got into this whole mess to begin with

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.

I'm so disillusioned, I almost don't even care who gets the FIFA Peace Prize next year

The goals and sending-off won over countless American fans, but Flo Balogun's comments today should win over even more ❤️🤍💙 📸: @tombogert.bsky.social

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

Way ahead of you, GMU Emergency Alert System. The World Cup is on and I've decided to limit all activities both outside AND inside.

Claude Code just told me that the version of Ruby I've been using on my laptop is "ancient". And now I feel old too.

Machine Learning is causing massive leaps everywhere. Also in Economic History. There is a conversation we need to have. What ought to be the new scientific standards? Together with two coauthors . Our argument: We should maybe care a bit less about accuracy 📝🧵

"The share of Harvard undergraduates receiving disability accommodations rose from roughly 3% in 2014 to 21% in 2024 — a sevenfold increase in a decade... Meanwhile, at community colleges, the rate is 3 to 4% and has not changed in a decade." www.bostonglobe.com/2026/06/29/o...

The great economist Alberto Alesina passed away unexpectedly six years ago. The next day, his former PhD student @sethsd.bsky.social posted an explanation for Alesina's incandescence as a scholar and mentor. I've thought about his words many times over the years. medium.com/@sethstephen...

I found this absurdly amusing: www.youtube.com/watch?v=PZHR...

Was watching an instructional video on reverse de la riva and my wife walked in and looked at me like I'm weird. I have no idea why...

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 thanks going out to Amazon for ruining their book search on the app by integrating ai into it.

"The only acceptable religion is my religion" is an especially common belief in Islamic countries. www.graphsaboutreligion.com/p/54-countri...

I'm not sure I've ever seen a single sentence go downhill this far and this fast

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.

I have the best helper chef for Father’s Day.

I am enjoying the booing of the ad breaks.

@alextaylorecon.bsky.social and I have a new paper. Using embeddings of ~800k book titles in Europe 1450-1650, we find higher market access made a city's print output more topically broad and mainstream. Also, useful-knowledge content predicts city growth. www.dropbox.com/scl/fi/iez0u...

This looks absolutely incredible. @lars.vilhuber.com I think you're going to love this

Found a cool result I checked my code Now I have correct code

Wake up baby, new smartphones and fertility evidence just dropped. 🙈 www.nber.org/papers/w35310

I guess we have a duck in our fireplace. 🦆

I quite like this idea -- a tax break so that every family can more easily afford to subscribe to a newspaper of their choice.

This article brings back memories. The first, and only, time I've ever been mugged at knife point was in the late 80's skateboarding at this site. Was still fun. www.nytimes.com/2026/05/30/a...

Apparently, this is the case. Here is the relevant passage from the successful 2018 proposal by the editors of APSR, in “Proposal to Edit the American Political Science Review,” October 2018, submitted in response to this call: politicalsciencenow.com/call-for-pro...

Could this possibly be true of APSR, the flagship political science journal, that, from 2020-2024, it based whether to send articles for peer review based on author race and sex? www.goldwaterinstitute.org/policy-repor...

I love the difference in translation for this product. Says much about the difference between the two cultures.

New working paper with Amol Singh Raswan and Chris Udry: "The Sisyphean Pursuit of Evidence for Poverty Traps." A central idea in development economics is that poverty can trap people. We went looking for the cleanest evidence. Here's what we found – and didn't.

Here is Elon Mush bragging about how he "accidentally" canceled all Ebola prevention efforts.

I don't mean to brag, but my 10 year old is obviously an artistic genius...
