All roads lead to Rome, they say. - And finally you too can find out if that's true! 😉

Digital map lets you explore the Roman Empire's vast road network
Archaeologists have compiled the most detailed map yet of roads throughout the Roman Empire in AD 150, totalling almost 300,000 kilometres in length

I've been thinking a lot lately of a quote from Leo Strauss: A theoretical crisis does not necessarily lead to a practical crisis.
The Constitution has collapsed as a meaningful organizing framework for American politics, but like the Roman Senate meeting in 603AD, some things keep going.

Guy whose concern about the No Kings rally is that there’s a lot of evidence constitutional monarchies do a better job than republics of avoiding personalistic politics.

Elated at Joel Mokyr's Nobel Prize! You can find numerous accounts -now multiplying by the minute- of his scholarly contributions. Today I want to celebrate the man and the mentor.

Mokyr's work could not have been done today in most economics departments, but the irony is that his work would not fit in history departments today, either. Methodologically he seems more 'history' than 'economics' to economists, but the content and reasoning are too 'economics' for most historians

I just checked JOE and I count 3 adds for economic history positions (I’m not counting the “any fields”). There seems to be a bit of a gulf between what the Nobel committee is recognizing and what Econ departments think they should be doing.
That's like four economics awards in a row with a substantial economic-history component, right? That strikes me as a remarkable shift. www.nobelprize.org/prizes/lists...

Science marches on. Also, I’m not eating this.
Scientists revive old Bulgarian recipe to make yogurt with ants. Ants carry lactic and acetic acid bacteria that help coagulate milk, as well as formic acid to acidify it. They even partnered with Danish chefs to create three recipes using ant yogurt. arstechnica.com/science/2025...

Pierre Bourdieu was on to something… #theinheritors
I was better informed than a lot of grad students about a lot of the hidden curriculum, but this stuff was *totally* invisible to me, and it took me years to see it and understand how important it was.
• Children of PhD-educated parents are 28 times more likely to become professors than those whose parents only completed compulsory school.
• Children of professors are 11 times more likely to join the faculty than everyone else.
