Outreach
Here are a few documents that came out of various outreach endeavours. Feel free to use them at own risk.
For KU Leuven's summer of science, colleagues and I designed some number theory projects for high school students. versie in het nederlands.
I made an escape room using Euclidean geometry clues for use in high school classrooms, email me if you want the documentation. I plan to refine the design and share it publicly later.
For the problem-solving enthousiasts: while volunteering for VWO I proposed a number of problems, here is a collection of some of these problems. At the bottom of the linked page I also list some high school problem solving and number theory resources. Ik schreef ook cursussen voor de olympiade training van VWO (combinatoriek, getaltheorie, veeltermen). Stuur me een email indien je graag een kopie wilt.
Hier zijn enkele van mijn favoriete problemen in combinatoriek die ik eens heb verzameld toen ik assistent was voor het vak 'Discrete wiskunde' aan de KU Leuven.
Some rather old notes for PROMYS talks -- beware of mistakes and a crammed writing style: Bernouilli numbers, Dedekind sums, Hilbert's tenth problem, graph coloring

some personal opinions
In the ongoing earth destruction (of which climate collapse is only one disaster), we should absolutely minimize flying movements. At the universities this means we should mostly attend local seminars and conferences. Let us not stop talking about caring for the planet and its earthlings. I endorse initiatives such as CAGE.
I avoid using GPTs and other generative AI in classroom tasks. we should all be raising more awareness about the ecological risks that AI data centers create, like the huge consumption of energy and water, the generation of new hazardous waste and their strong dependence on unsustainably mined rare earth minerals, see this UN report or this MIT report. We should also be warned by the terrifying potential geopolitical threats. It is severely worrying how much irrepairable ecological damage AI and its data centers are already creating, how much generative AI fails to be transparant technology, and how it kills human creativity and undermines expert authority in the long run. Let the humans learn from their own mistakes, not the mistakes of machines. At this moment, it is not clear to me if 100% ethical, sustainable and transparant generative AI research can even exist. Please prove me wrong and send me counterarguments. Occasionally I use Confer, it is a open-source encrypted alternative to chatGPT, and does not sponsor criminals like Trump.
Universities and governments should follow legal obligations dictated by international law -- in the midst of an extraordinary humanitarian crisis and brutal genocide by the Isreali government I fully support the public letter of Belgian Universities for Palestine which carefully questions the existing collaborations with institutions based in occupying countries. I also signed the Belgian Citizen's Bill for Palestine Echoing the Call for Justice. Everyone should consider taking action to put academic and economic pressure on the Israeli institutions as well as to put political pressure on local governments to recognize the Palestinian state unconditionally. And let us also not forget to keep raising our voices for oppressed people in Iran, Sudan, Congo, Yemen, Kurdistan, Afghanistan, ...
