La SNCF pourrait choisir Starlink, le vaste réseau de Musk, pour équiper ses trains de la technologie satellite face à son rival européen Eutelsat. En septembre dernier, SpaceX a déjà été sélectionné par Air France-KLM pour installer progressivement le wifi à bord de tous ses avions. Confier nos moyens de communication dans les transports à un milliardaire fascisant, une riche idée! https://www.lalettre.fr/fr/entreprises_tech-et-telecoms/2025/07/03/le-plan-d-elon-musk-pour-brancher-les-tgv-francais-sur-starlink,110472501-eve

The new science video from #Veritasium is wild and worth a watch.
It's about Braess’s Paradox, which I'd not heard of before, but it shows up in all sorts of places, including traffic planning.
The video includes a fantastic couple of examples of why car traffic times can sometimes go up when more roads are built. That's not the usual case of more people using the roads. Instead, with the same number of drivers, adding a road makes everyone's journey time slower.
This example might seem a bit contrived but the video also cites a study where the equivalent did happen when a busy street in New York City was closed off, and travel times for everyone paradoxically went down.
Physics and maths are wonderfully counterintuitive sometimes.
