Die zeitliche Abfolge der Geschichten von Asterix und Obelix - Abhängigkeiten von hist. Zusammenhängen und der Abfolge der Asterix-Abenteuer. Ein ziemlich langer Thread in 15 Teilen als Einleitung zum Weiterlesen auf Comedix.de, dort mit interaktiver Zeitleiste.

New @cep-lse.bsky.social WP w/ Luna Bellani & @anselmhager.bsky.social: Did Southern elites lose power after emancipation? Using 7,000+ state legislators (1850–1880), we find the opposite: former slave owners gained committee influence post-Civil War. No similar shift in the North.

New paper in Nature. The more a government controls its domestic media, the more it dominates AI training data, the more pro-regime outputs we get from AI. By scraping the open web, LLMs are unwittingly laundering state-coordinated narratives into seemingly objective answers.

By way of illustration, here is a graph from my 2022 JEH paper with Luna Bellani and Anselm Hager, showing the share of Texas state legislators with a slaveowning background over time. As you can see around 1877, you can't see anything- Reconstruction in Texas had all but ended by 1873.

This 100%. The compromise of 1877 is one of the more overrated events in US history.

Terrible example of the power of rankings and their misuse

So you're telling me that cutting tariffs leads to lower prices? Fascinating.

The World of Yesterday: Stefan Zweig, great Austrian writer, poet & translator, witness to collapse of Habsburg Empire & rise of Nazism; died in despair in 1942. His memoir Die Welt von Gestern was published just after his death. The best English translation is by Anthea Bell (2013).

When it comes to finding an EU anthem, the strategy of going with one of Beethoven's most recognizable bangers as opposed to commissioning some sort of new Europudding tune was a stroke of genius.

Pretty cool rubric- would like to see that for other elections as well. If widely published, it could also help disciplining the post-election bullshit as parties try to put their spin on results.

esut.de/2026/05/fach... Interessanter Überblick.

To clarify: This does not necessarily mean the policy didn't work- the paper finds overall social gains, but mainly via consumer surplus, not CO2 reduction. So the verdict for it as a climate policy is likely different than as a social policy

"The additional train demand substantially worsened rail service quality: the share of delayed trains rose by roughly 30% overall" Increasing demand for an already shaky train system without a commensurate supply-side investment increase wasn't the best idea...

If you want just one chart to help you to evaluate how you should live your life, this one might be it... Enjoy your children while you can; call your friends and family a bit more often; learn how to enjoy your own company.

After speaking to people that were more informed on the matter than I am, I can say that Germany is no longer considering the adoption of Typhon as a guaranteed thing, with other deep-strike options like land-launched variants of the French MdCN, Taurus NEO and 3SM being considered. 3/6

“.. On Polymarket, the Journal found, 67% of profits go to just 0.1% of accounts. That means less than 2,000 accounts netted a total of nearly half a billion dollars.” @wsj.com www.wsj.com/finance/inve...

Usual topic, but different language for a change

Indeed.

"Europeans should start crash programmes to pair available air- or sea-launched cruise missiles, such as Storm Shadow/SCALP-EG, Taurus or the French Naval Cruise Missiles (MdCN), with range-extension boosters for ground launch."

Spent some time researching the Multi-Domain Task Force concept for a book project, and want to emphasize one thing:

Some thoughts on the United States ending plans to deploy a Long-Range Fires battalion to Europe: I am somewhat less alarmed about what this means for Germany and Europe. 1/6

This will be the most consequential midterm election since 1866. Already it has been crazy, with the president and a highly partisan SCOTUS driving partisan gerrymandering with the express purpose of defying the will of voters, for one example. But 1866 was worse. It offers hope for 2026. 1/

In the early evening of May 2, 1863, the 12,000 men of Maj. Gen. Oliver Otis Howard’s XI Corps were eating their supper when the 28,000 men of Stonewall Jackson’s corps came boiling out of the woods, striking the right flank and rear of the Army of the Potomac.
