Mathematics is a powerful language, but getting acquainted to it can be painful and discouraging, especially if you are not really interested in it. But it can be different!

When biologists can't explain cubic wombat poop, why don't THEY call it a singularity?

2-panel SMBC comic update. The first panel has a narration box saying "Caveman" where two cavemen are looking out at the ocean. One says "us not know what on other side of ocean." The second panel has a narration box saying "Caveman Physicist" where the same caveman now says "Past ocean... Science breaks down. Is Ocean singularity" as the other caveman marvels.

In September I have joined our University Council, a co-participation body that monitors the activities of the Uni Board, issues (un)solicited advice and has a say in some important decisions.

What we do can sound a bit mysterious and I hope I can make it more transparent by blogging about it :)

Our first month in the University Council

A month has passed since the new University Council (UC) was installed, and I think it’s time to look back on what has happened so far, and what seems to lie ahead. When I enlisted I promised myself t...

I am so happy that I took the time to watch @veritasium.bsky.social talk at the @perimeterinstitute.ca and if you care about #education I would strongly recommend to take the time too

Marcello Seri @mseri.me · 8d

The best thing about education isn’t access to information, it’s being in a room with a good teacher, likeminded engaged peers, and time to talk. Education is a social activity. Tech hype misses the point: the real challenge isn’t delivering info, but creating meaning together

> The message for practice is clear. A single quiz at the end of a lesson is a start, but not enough. Retrieval practice is most effective when learners receive repeated opportunities with feedback. This, […] is key […] (to) also build the ability to use knowledge flexibly when it really matters.

What do you think about all this @gerardrve.com as a privacy law expert?

Marcello Seri @mseri.me · 13d

#ChatControl is a dangerous development at the EU level, after many failed attempts it looks closer to becoming reality than ever. Detailed information on what is it about and why it is not a good idea can be found in many places, like the link below.

ChatControl wants to scan all your private messages

The EU is pushing legislation that would scan all our private messages, even in encrypted apps.

The uni cuts top-ups and demands refunds from PhDs after their CSC scholarships were raised; yet some contracts don’t even tie top-ups to CSC amounts. Our @therezalangeler.bsky.social raised this with the board in committee yesterday; to be continued in plenary!

This website has fantastic IKEA-style visualization of algorithms.
Here the quicksort example, idea-instructions.com/quick-sort/, but take some time to explore the others!

KVICK SÖRT

Quicksort is an efficient sorting algorithm based on a divide and conquer approach. Choosing the dividing element at random is a good strategy to avoid bad worst-case runtime.

Mijn oprechte complimenten aan wie dan ook het idee van het nieuwe AH‑cadeautje had en aan de genie die ze zo verbazingwekkend precies heeft ontworpen 🤯
