New video! This was supposed to be my entry for the fifth Summer of Math Exposition which ended on... August 15th. Two solid month late, but at least it is done.

it's vital for your mental and emotional development to

AAAAAAAAAAH! We have an internal wiki which is your typical WYSIWYG online CMS thingy. I fixed some text on a page and tried to answer a colleague's comment, but couldn't find out how to do the latter. Turns out: you cannot create or answer comments in edit mode.

Oh, there are much better and funnier Go proverbs! Guess it's time to start editing Wikipedia.

Started to tell (a sanitized version of) the story of Dragonball to the four year old, and he's hooked 😂

I obviously enjoy @tomscott.com's England series as a documentary about... stuff. But the strawberry episode today once again reminded me how much I love to see all the people excited to talk about their projects. Just a bunch of fantastic nerds.

Still my favourite gaming experience of the last few years. And 100% mandatory for all math students!

Why the fuck is speedcubing of all things split into gendered categories? (Retorical question, of course.)

Das Kind hat sein Seepferdchen!

Faszinierend wie viele "historische Debakel" eine Partei in so kurzer Zeit haben kann.

FieldExplores woke up today and chose violence.

The four-year-old is grasping the concept of "secret superhero identities"and it is adorable!

Ha, our four-year-old can read two digit numbers and is very cautiously learning to write them. (With the usually, very adorable hiccups.) And very fun: when he says the digits of a numbers, he says the ones place first, and the tens place second.

The four-year-old watched his first episode of Spider-Man. We are now a Spider-Man household.

Oh, the Bavarian joy of watching supermarkets trying to display Oktoberfest, Halloween, and Christmas products at the same time.

Big day for the four-year-old: he learned what ninjas are, and also that Bielefeld doesn't exist.

Watching "The Fast & The Furious" right now. Apart from the nostalgia for flip phones and the excellent music of the 2000s, it hit really hard when Brian looked up the way to somewhere on an actual physical map.

Jo! YouTube just put "Me at the zoo" on my feed! I know why and it is irritating, but still a bit cool.

Endlich Lebkuchen im Supermarkt!

Oh, a rare Betteridge exception!

Now that he is exposed, I can finally say that I never liked this Melville guy.

The peer review for the Summer of Math Exposition 2026 just started! Join at some.3b1b.co, watch/read/experience over 200 fantastic math explainers and help us give feedback to the creators!

Not really playing simulator games these past few years, but 👀

Watch the thing. Had to carry our tired, but excited kid up and down the hill, but it was worth it.

I'm this 🤏 close to hiring an editor just so I don't have to hear my voice any more.

The following theorem has, apparently, many names: en.wikipedia.org/wiki/Interce... For all native English speakers, which name do you know this as?

Reading a story with the four-year-old and a Dachshund appeared. I wanted to explain to him why they look like thak, so I asked: "Do you know why they look like that?" And he answered: "Because they grew like that; they were born like that." And, yeah, 100% correct. Completely shut me down 😅

Taught the kid about stinning nettles on our forest walk. And now he stops at every plant to make his judgement 😂

Been writing quite a few hot takes lately, and I am so happy that Bsky introduced the draft folder so that I can post them there.

Ist im April komplett an mir vorbeigegangen, aber es gibt eine Podcast-Folge mit Amina Zerouali, die dort unser Lernspiel "Chempion" vorstellt:

Oh, this is wild, LMAO. Everyone, listen to this episode! The tl;dr for the peeps in academia: Remove the comments from your TeX files before uploading them to the arXiv. And don't put any sensitive data in there in the first place.

Ha! My mission badge finally arrived! That's what? Two additional months to get it from the UK to Germany? Brexit, such a good idea.

LMAO, if you innocently try to get an angle to a cos value, Wolfram|Alpha will use slope degrees:

Last week, the German Education Conference awarded me the "Best Reviewer" award. I think I would have preferred if they had accepted our paper instead, but I'll gladly take it 😄

This, of course, has nothing to do with generative AI. Don't send information to websites which you are not comfortable being publicly visible. That has been true 40 years ago as much as it is true today. (And, in particular, don't press the button that says "publish to the web", FFS.)

Having to use Excel sheets that you send back via email as your data form is truly the Dark Souls of user surveys.

So, what's this recent plague of YouTubers blurring the main subject in their thumbnails, but, like, badly?

Very tempted to make a tier list of villain/henchmen couples and how well they adhere to the kiki-bouba dichotomy.

The four-year-old is playing a made game with numbered cards with his Mum. Out of nowhere he said "Zero is the first number, and one is the second". I am very proud 😅

Love how everyone immediately knows who that was.

Kann mir eigentlich jemand die SPD erklären? Nein...? Okay...

What do you mean Fox McCLoud is 18?! 😭 Can't you make him, like, 25 or something?

First home-made pizza using a proper pizza stone.

I can even forgive the helmet.
