Le paradoxe du grand-père est une boucle temporelle fermée qui crée un paradoxe. L’idée foireuse consiste à retourner dans le passé pour faire passer le goût du pain au grand-père. Forcément, vous pourrez plus naître, or vous êtes né sinon vous seriez pas là pour lui faire un mauvais sort. Salukes

La brachistochrone est la courbe de moindre temps dans un champ de pesanteur. C’est donc le chemin le plus rapide, mais ce n’est pas le chemin le plus court.

C’est officiel, le printemps astronomique vient de commencer. L’équinoxe de printemps s’est produit ce vendredi 20 mars à 15 h 46. À cet instant précis, le Soleil a traversé l’équateur céleste et les deux hémisphères reçoivent exactement la même quantité de lumière. Jour et nuit à égalité parfaite.

Les astronautes d'Artemis II vieillissent-ils moins pendant le tour Terre-Lune ? Intuition immédiate : vitesse → relativité restreinte → vieillissent moins.

Peut-on passer à travers deux portes à la fois ? Dans la vie de tous les jours c’est impossible, mais dans le monde de la quantique, c’est possible. C’est la fameuse expérience de la double-fente. Les fentes sont les portes et les électrons sont les électrons. Salukes #science #physique

Avec les infinis, on peut faire des calculs bizarroïdes. On peut même démontrer que 1 = 2. Si 1 =,2, alors on peut démontrer toute chose et son contraire aussi. Bref, c’est le foutoir et la mathématique est par terre. Salukes #science #physique #profbucella #lasciencepeuttout

C’est quoi le paradoxe des trous noirs ? Ces objets sont prédits par la théorie et pourtant ils prédisent la fin de la théorie. Salukes #science #physique #profbucella #lasciencepeuttout

Custom music in games like Dead As Disco is great because you can make fights as epic or silly as you want :p

Well, that isn't the word I would’ve used. But then I don’t own the Trump-to-English dictionary. A large faction of Americans is in an abusive relationship, and they don’t seem to care that they are.😢

"My paycheck goes straight to rent -- there's nothing left." How many Canadians see 50-100% of their income get sucked up by land rents and income taxes? We should untax work, and shift taxes to the rental value of land.

Russia tried to shoot down a stork with an FPV drone. The stork dodged it. Ukraine's national symbol of peace is apparently also better at evasive maneuvers than the Russian army. Support link is in our Bio.

A partner who supports your growth is a green flag. Not just when things are easy, but when you’re trying something new, improving yourself, or stepping into a bigger version of your life. The right support builds confidence instead of shrinking it. #relationshipadvice

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.🤦🏾‍♂️

Good nutrition and health do more than help children survive. They help children grow, learn, and dream bigger for their future. In 2025, 347,791 malnourished children and pregnant and breastfeeding women in 26 countries received life-saving treatment from World Vision. 🧒🏽👧🏾🧒🏼

A lot of the hype has been about Joseph Dzierwa and JT Quinn, but there's another pitcher from Orioles' 2025 Draft class off to a strong start. LHP Caden Hunter (6th-rounder) had 9 K's in 4 innings of 1-run ball today for Single-A Delmarva. The 22-year-old has a 1.17 ERA in 6 games.
