Numerologists take note: tomorrow, 27th September 2025, is a square date in both US and Everywhere Else notation. 5205² = 27092025 and 3045² = 9272025 This is the last time this will happen for a thousand years! (from @EdPeggJr on math-fun)

I made it!!! Thanks, everyone, for keeping me company! #DeutscheBahn #Travel #Trains #Haribo #germany

While I'm being Deutsche-Bahned for the fourth time today, my friend in Singapore tells me that the MRT had no less than three disruptions this month, so I guess public transportation is going to shit everywhere in the world. #Singapore #DeutscheBahn #PublicTransportation #Trains #Travel #commute

70 minutes into my 9-hour journey and I have already been Deutsche-Bahned 😭 #Trains #DeutscheBahn #travel

Men on trains: please don’t touch me. I’m so tired of this shit.

Yes, this movie is pirated. I gave it 3.14159 stars ⭐️

Het is nog heel pril, maar er is geen tijd te verliezen! https://nerdvote.nl/ is er om ieder kandidaat-kamerlid te steunen wat zich kan en wil inzetten voor veilige en verantwoorde ICT, en dat we niet onze hele overheid en maatschappij uploaden naar Amerika! Als eerste actie op de site […]

Interessant initiatief van @bert_hubert: https://nerdvote.nl/ Het idee is om elk (kandidaat-)kamerlid te steunen dat zich hardmaakt voor minder afhankelijkheid van (Amerikaanse) Big Tech, meer privacy, meer cybersecurity (looking at you, #Bevolkingsonderzoek & #clinicaldiagnostics#bevolkingsonderzoek Van de site […]

It’s less known but Theseus also had a car

Submitted a potentially high impact paper to Nature Climate Change. They have rejected and suggested NPJ atmospheric science. Frankly, I don't want to spend enormous amounts of money at Springer, I was already ambivalent about NCC. So where next? I'm thinking maybe the Cryosphere? But perhaps we […]

Vaccine deniers bringing back contagious diseases and causing everyone to drive instead of taking public transportation thereby making us miss our climate goals is a link I hadn’t made before. https://gothamist.com/news/nj-warns-path-light-rail-riders-of-possible-measles-exposure

@willowpje wat ik heel slecht trek is dat niemand me uitlegt waarom dat laboratorium zoveel gegevens moet hebben? Buisje met streepjescode testen, resultaat met zelfde streepjescode terugsturen. Dat zou het toch moeten zijn?

Many EU member countries have a rich colonial past, e.g. France, Spain, Portugal, the Netherlands, Belgium... (I know, Germany too - but this is off my topic here.) Do you know any museum from any of such country who would be interested to work with us on a European funded project about taking […]

Sinds NRC Handelsblad NRC werd, was het onduidelijk of het 'het' of 'de' NRC is. De onduidelijkheid wordt door de krant in stand gehouden door nooit een lidwoord voor de naam te zetten. Maar nu schrijft de redactie: "NRC heeft de samenwerking met haar correspondent in Spanje beëindigd". 'Haar' […]

Mathematicians: What are the important *definitions* in your field? For example, in topology the notions of compactness and of Hausdorff space are crucial (among many others). Or in complexity theory the notion of NP-completeness. And so on. Can you list the ones in your mathematical field? […]

Gemiste kans om het museum niet Zeesluis IJmuiden te noemen, maar meer bezoekers trekken door de voordeur af en toe van het slot te doen is wel een briljante zet https://nos.nl/r/662513
