On the train to Karlsruhe, paying our German colleagues a visit. Tomorrow morning I talk on physics with the CMS experiment - they gave me 45 minutes! 🌴🍹 A different scope, but next week Monday in the CMS week I'll have to squeeze everything in 20 minutes 😱

Perks of being at CERN... Today I saw by chance an old friend back, Abdel Djouadi. He is an absolute world authority in Higgs physics, but I met him in my first PhD year, just being fun, friendly, and scientifically curious with new students. So nice, it made my day!

Doing admin tonight for the French school transport. Horrendous website navigation (how to change my address !%$#?). This reminds me a recent discussion here (about taxes etc); we all agreed there is almost no way to be sure we're doing things the way they are supposed to be done. Too complex.

Jef Maes slaat weer nagels met koppen vandaag in De Morgen. De rode begrotingscijfers maken deel uit van een bewuste strategie om de sociale zekerheid 'uit te roken'. Deze legislatuur alleen al bijna €2 miljard aan bijkomende kortingen voor bedrijven en €6 miljard voor belastingsverlagingen.

We moved to CERN last week with just a 2-week temporary housing. Not ideal for our daughter starting school, but it was too difficult to arrange ahead of time. Luckily this weekend it looks like we found a nice place!

Voor de politici die hun post-reces dossiers voorbereiden: tot nu is 2026 uitzonderlijk, maar eigenlijk niet out-of-the-blue. De stevige trend keren (bovenste 📈) zal moeten (maar veel inspanning kosten) én 2026 is voorbeeld voor nabije toekomst, waaraan we ons moeten aanpassen. Hop, aan het werk!
Bovenaan: grafiek van de afwijking van de gemiddelde temperatuur van elk jaar tov het gemiddelde in 1900-1950 (januari tot augustus), in Ukkel. De laatste 70 jaar neemt die afwijking toe, 2026 met een afwijking van +3.4°C heeft ongeveer 0.5°C hogere waarde dan de tweede hoogste. Onderaan: staafgrafiek van de afwijking van de gemiddelde temperatuur per maand, van januari tot augustus, tov de gemiddeldes 1900-1950. De waarden variëren van 1.5°C tot 4.7°C.
