D'où vient-il qu’on se rappelle du passé, mais pas du futur ? D'où vient-il que le temps s'écoule dans un sens et pas dans l'autre ?

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.

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

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).

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 les tuiles s’arrachent du toit en cas de tempête ? C’est à cause de la vitesse du vent qui crée une dépression. C’est l’effet Bernoulli. Salukes #science #physique #profbucella #lasciencepeuttout

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.

I will never forgive exmayor Bruce Harrell and his goons and nazi cops for allowing this attack on the citizens of Seattle’s Capitol Hill neighborhood over last year’s Memorial Day weekend. They protected the hate group and attacked me and my queer neighbors. Never again!

Carbon capture is essential if we’re to survive. The fact of the matter is that CO2 levels need to be reduced to ~350ppm. The only way we can achieve that is to reduce emissions massively & increase natural carbon sinks to a point where we are decreasing atmospheric greenhouse gas concentrations.
