Die Idee, kritischen Umgang mit Social media Inhalten um Informatikunterricht zu vermitteln, verstehe ich nicht. Das ist ein technisches Fach. Auch wichtig, aber etwas anderes. Gebt lieber dem Sprachunterricht mehr Platz, da geht es immer schon um den kritischen Umgang mit Texten.

If you're new to the Headline of the Year contest, it's surprisingly elaborate -- for the next few days, I'll be keeping track of reposts & likes on here and elsewhere (mostly here it seems at this point) and that will seed the top 16 headlines.

Then-- a four-round knock-out battle for the title!

This morning I learnt another great example of why units matter - the flight of Air Canada 143 ran out of fuel at an altitude of 41.000ft.The Pilots managed to glide the plane down safely with their 70 passengers. The jet had been loaded with 22,300 pounds of jet fuel instead of 22,300kg

George performed a diffraction experiment that confirmed de Broglie's hypothesis for electrons! This led to a Nobel Prize in 1937.

So J.J. Thomson, the father, discovered the electron and regarded it as a particle, while George Thomson, the son, showed that the electron diffracts like a wave. (8/n)

TIL: Earth's jumping frog radius is approximately 1.5 light-days, leading to general relativity's successful prediction that all the frogs in the Solar System should be found collected on the surface of the Earth.

Another way to restart the world’s idea machine is to restore funding and grants to universities, researchers, and artists.

America, you have spoken loud and clear: You do not like AI. But what if AI is the way to restart the world’s idea machine?
We’re running out of good ideas. AI might be how we find new ones.

I just came across it again in my French course: épeler vs. to spell – and it fits perfectly…
You can often swap the É at the start of a French word with an S and get closer to the English equivalent:

🇫🇷 État 🇬🇧 State
🇫🇷 Étude 🇬🇧 Study
🇫🇷 Étrange 🇬🇧 Strange
🇫🇷 Écoute 🇬🇧 Scout (seriously, they're related)

But why?

@jesszafarris.bsky.social and I have been talking it out.

One of my favourite examples is 'biceps', both in English and in Dutch.

In Latin, 'biceps' consists of 'bi-' (two), 'cep-' (head), and '-s' (case ending): "two-headed".

However, since the 1800s, 'biceps' has been reanalysed as a plural and given a new singular: 'bicep'.

The Latin plural is ... 1/
Some people vocally oppose using ‘data’ and ‘panini’ as singular nouns, saying they come from plural nouns.

That’s true, but that also goes for ‘marvel’ and ‘joy’: they used to be plural too.

And ‘cherries’ and ‘peas’ used to be singular.

Zoom in to learn all about this phenomenon: reanalysis.
