Pourquoi un vélo tient-il debout ? C'est le phénomène d'auto-direction. Quand le vélo penche sur le côté, l'avant pivote spontanément du côté de la chute. Le point de contact se trouve sous le centre de masse et il redresse le vélo. Longtemps, on a cru à trois effets combinés :

La phyllotaxie de Vogel fait apparaître naturellement le nombre d'or. Si vous placez des graines une à une autour d'un centre, le rayon croît comme √n parce que la surface occupée par n graines doit croître linéairement avec n (chaque nouvelle graine prend la même place que les précédentes).

Quand deux trous noirs se frôlent, ils emportent un peu d’énergie en ondes gravitationnelles. Pour la calculer exactement, il faut une variété de Calabi-Yau à six dimensions. L’idée géniale a été d’importer dans la relativité générale l’arsenal de la théorie quantique des champs.

Eden Hazard on replacing Ronaldo: “I never went to Real Madrid to replace him. The media created that narrative. I have completely different style. I couldn’t score 60 or 70 goals a year, in fact, I barely scored that many in my entire career. I went there to play like Eden, not to replace Ronaldo."

Wife made fun of my creation by saying "Feed me, Seymour!". Point taken, there's actually no need to keep any one band on top of everything else. Fixed! And that's another beautiful thing about this approach - It's easy to go in and change up the "intersections" / layering order.

trump sees "falling" as SO embarrassing, he's LYING on 60 Minutes about what we all saw last night: His ass fell like a sack of rotten potatoes. 60 Minutes didn't even show the clip. But I have 2 different angles. Why lie about it? Such a weird clown.

It’s infuriating. The mayor’s dishonesty isn’t just a disappointment; it’s a betrayal of the public trust that we’re supposed to be able to count on. When those in power treat the truth as optional, it undermines the entire democratic process. Thank you for refusing to be silent about it.
