La conservation du moment angulaire peut se voir de la manière suivante. On calcule la surface que balaye la masse par unité de temps. Cette quantité doit être constante. C’est fondamentalement la seconde loi de Kepler, dite loi des aires. La physique est pas compliquée.

Le CNRS annonce en grande pompe la première observation en direct de la rotation d'une pouponnière de planètes.

Pourquoi faut-il absolument construire des fusées à étages ? C’est l'équation de Tsiolkovsky. Ça se prononce toujours comme ça s'écrit, mais ça s'écrit jamais comme ça se prononce. Salukes #science #physique #profbucella #lasciencepeuttout

Comment reconnaître la face cachée de la Lune ? Des cratères à perte de vue, aucune mer lunaire, les taches sombres qui caractérisent la face visible. Sur la face visible, c’est pas qu’il y a moins de cratères, c’est que les mers les ont recouverts. Salukes #science #physique #lasciencepeuttout

Où sont-ils tous ? Fermi parlait des extra-terrestres. Il devrait y en avoir pleins, or on ne les voit pas. C'est le paradoxe de Fermi. Salukes #science #physique #profbucella #lasciencepeuttout

La conjecture de Riemann concerne les nombres premiers. Tous les zéros non triviaux de la fonction zêta de Riemann ζ(s) ont pour partie réelle ½. Autrement dit, ils sont tous alignés sur une seule droite verticale du plan complexe, la droite critique.

Pourquoi y a-t-il quelque chose plutôt que rien ? s’était demandé Leibniz (contemporain de Newton). C’est la question la plus puissante qui borde la physique. En effet, elle est tellement puissante qu’elle ne relève pas de la physique.

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.

Le lundi 6 avril, les quatre astronautes d’Artemis II vont faire leur tour de la Lune. C’est le plus loin qu’aucun humain ait jamais été, soit 406 773 km de la Terre.

Connaissez-vous le paradoxe de l’interrogation surprise ? Voilà le genre de gags auxquels s’amusent les physiciens entre deux équations. Salukes #science #physique #profbucella #lasciencepeuttout

Whitehouse: "Callais is gonna drive up voter participation. This makes voters angry. When you see leading Black members of Congress have enjoyed respect of their states redistricted out office by political manipulation, that gets you mad. Let's make sure they lose where they can't redistrict"

We could write a #DidntAgeWellDonald book! Bush lied & Clinton’s impeachment was unimportant Question about Iran, How many false pretenses?

The same in his warped brain. Trump lied his way into a job he knew he couldn’t do because he didn’t respect the people who did it and made it look easier than it actually was. The first time, now, he came into office, he was prepared to ruin the world and steal everything that wasn’t nailed down.

Another week of failure in Iran. Another week of precious American resources being squandered halfway around the world, benefiting no one but Benjamin Netanyahu and Big Oil.

Argentina’s far-right government blames Indigenous Mapuche communities for the wildfires that have devastated Patagonia in recent years. But judicial investigations have found no evidence to support this – despite officials suggesting links to “terrorism”. The real evidence points elsewhere. ⬇️

Love Talarico blasting Paxton’s 'vegan' jabs with Texas BBQ: 'I’ve been eating BBQ since before Ken Paxton’s first indictment.' Brilliant. While the GOP is morally bankrupt, Trump is still the only one who survives being an unabashed criminal. Paxton can't be the second. Texans must reject him.🤦🏾‍♂️
