S3E04 - Becoming a teacher with Heleen van der Ree and Gerrit Roorda by It’s Not Just Numbers In this episode, Heleen van der Ree (NVvW – Dutch Association of Teachers in Mathematics) and Gerrit Roorda (Teacher Educator, University of Groningen) join us in a conversation around what it means t...

What does it take to become a math teacher in school?

We sat down with math teacher trainers and coordinators to find out. We talk about the rewards and challenges of being teachers, and discuss creative ways to inspire students.

New blog post: I got tired of having repetitive arguments explaining why I think it’s OK to be skeptical of LLMs for coding, so I wrote six and a half thousand words on the topic that I will be referring people to from now on.

The machines are fine. I'm worried about us. On AI agents, grunt work, and the part of science that isn't replaceable.

I could not agree more and share the worry. It feels to me that this applies pretty much verbatim to mathematics as well

A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

More context on this #Artemis II image:

* This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right

* The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon:

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

The more fascist underfunded and limited our basic science becomes the fewer divergent or dissenting voices will exist or will be heard. That's something to consider as we're quite obviously in those times. 5/

Abstract

Five countries account for over 80% of Nobel Prize–winning discoveries. Because high-prestige recognition redirects resources and talent, such concentration can be self-reinforcing, yet whether it originates in institutional design or individual evaluator behavior is unknown. We decomposed Nobel selection into a five-layer network spanning 8,134 individuals, 514,111 edges, and five prize categories (1901–1975). The Swedish and Norwegian bodies that oversee Nobel selection assembled a geographically diverse nominator pool, yet within it, nominators select same-country nominees 4.85 times as often as expected (p < 0.001), from 8.58 times in Literature to 3.01 times in Physics. This concentration persisted as the nominee pool diversified over seven decades. Geographic sorting enters at the discretionary nomination decision, not the institutional pipeline—a specific, targetable point in the selection process.

🚨 80% of Nobel Prizes go to folx in 5 countries. Why?

We analyzed 75 years of prize committees, nominators, nominees, and laureates... a network of 500k edges. Turns out nominators choose compatriots at 5x the expected rate — amplifying geographic bias.

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

Black and white portrait of Emmy Noether standing. She is in her early-to-mid twenties. Noether wears a long, dark skirt with a white blouse that has high shoulders. A dark belt with a shiny buckle is cinched around her waist. Her hair is pulled back, and she is looking slightly down and to the right of the photographer.

Emmy Noether was born #OTD in 1882.

She made groundbreaking advances in abstract algebra, but is probably best known for her eponymous theorems articulating the deep connection between symmetries and conserved quantities in physics. 🧪 ⚛️ 👩‍🔬

Exactly - I always say that the most important thing about a degree isn't memorising things, it's learning how to learn.

I don't use most of what I learnt in my astronomy degree on a day to day basis, even as a professional astronomer. But the independence & learning skills I gained are essential.

This was necessary (we actually had this as an item of concern during the deliberation on the European Strategy Update for Particle Physics). Preservation of knowledge by independent entities becomes more and more crucial. Thanks @arxiv.bsky.social
