Ce lundi 6 avril, les quatre astronautes d'Artemis II font leur tour de la Lune, c'est le plus loin qu'aucun humain ait jamais été. Ils se trouvent à 406 773 km de la Terre. Sur cette image, la face visible de la Lune est à droite. On la reconnaît à ses taches sombres, d'anciennes coulées de lave.

Pour fabriquer la mousse au-dessus du thé marocain, il faut le verser depuis une certaine hauteur. Plus la hauteur est élevée, plus la vitesse est grande. Au-delà d'une vitesse critique, le jet entraîne mécaniquement une gaine d'air dans le liquide sous forme de bulles.
On m’a demandé d'expliquer le concept de l’Univers bloc. Ce bazar découle en droite ligne de la relativité d’Einstein. En gros, le concept dit qu’il faut considérer l’Univers comme un bloc, avec le passé et le futur dans le bloc.
On va essayer de bien comprendre la flèche du temps avec un exemple microscopique (les physiciens parlent de micro-états). La flèche du temps devient alors une sorte de loi de probabilité géante. C’est plus fort que du roquefort. Salukes ✅ Vidéo longue sur le YouTube. #science #physique

En vérité, c’est pas le tout premier iMac qui est sorti et sur lequel j’ai terminé ma thèse. Ce modèle est date des années 2000. Le concept du iMac était de tout caler dans la boîte de l’écran qui entourait le tube cathodique : carte mère, alimentation, lecteur optique, disque dur, haut-parleurs.
