Marketing prof (U. of Cologne). Trying to figure out things.
Great essay by Thomas Basbøll (is he on bsky?) about the importance of writing and evaluating writing in academic education.

Europa fehlt der Wille zur Macht. Wir haben enorme Potenziale, einen riesigen Binnenmarkt, selbst die USA & China sind in wichtigen Bereichen von uns abhängig. Wir müssen diese Stärken strategisch und selbstbewusst für unsere Interessen einsetzen.

In the *Sign of the Broken Sword* (1911), Chesterton tells the story of a corrupt general who murders a subordinate and then orders a doomed assault on the enemy that results in thousands of deaths in order to hide his murder under a hill of corpses.

If the Golden Gate Bridge were constructed today using modern steel, it would require half as much material.

Every type of take-home assignment has been made so much easier with the use of current AI tools, to the point they cease to be appropriate evaluation of student performance. The fact that we still give take-home assignments is partly ignorance (Profs who don't use AI), partly denial / copium.

Maybe you know that about 78% of the air you breath is Nitrogen and almost 21% is Oxygen. But did you know that 1% is Argon? The remaining gases make up less than 0.05%.

Are large _language_ models actually large _text_ models? The whole idea is to model a corpus of training texts, not languages. Am I wrong?

I love receiving Christmas cards.

Most of all I love to keep the envelopes to scribble approximate numerical estimations on their backs.

If I were to define a temperature scale I would set 0 at 0C (freezing water) and 100 at 100F (body temperature). Two clear human-based scales.

Too hard to have an accurate sensation of water at boiling point.

And zero Fahrenheit is just as arbitrary as it gets.

I usually trust Google AI summaries to simple queries. But this answer to "What is an acre?" ends in a weird twist that made me chuckle.

Wrote a short piece arguing that higher ed must help steer AI. TLDR: If we outsource this to tech, we outsource our whole business. But rejectionism is basically stalling. If we want to survive, schools themselves must proactively shape AI for education & research. [1/6, unpaywalled at 5/6] +

Cone volume calculations reveal how much graphite in a standard HB pencil we actually use: even if you use the pencil until it’s completely dull, only about 33% of the graphite is used — the remaining 67% is wasted. If you sharpen it when it’s only halfway dull, the waste jumps to 90%.

Saturday morning I ask GPT5 to "tell me something about me" and among the list, I find the nicest of compliments: "Your style is iterative and meticulous — you like to refine, reorganize, and polish — but also boldly synthetic, seeking frameworks that connect ideas across domains"

Invincible characters are boring and this is among the reasons why *Andor* and *Mandalorian* are better shows than *Ahsoka* and *Obi-Wan Kenobi*.

Same why Batman > Superman

Also why James Bond is insufferable.

I’ve decided not to post my annual “women on the Econ job market” thread this year. Social media has splintered too much, and now that I’ve left academia I’m focused on other priorities.

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.

I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.

But what is a Laplace Transform?

Nobel for metal-organic frameworks!

Could we have had the technology earlier had we not spent the whole 20th century dividing organic and inorganic chemistry into different departments?

Probably something to be learned for the social / management sciences.
