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

Note aux lunettus : enlevez vos carreaux. Explication de la science. Le Nesquik, c’est à 75 % du saccharose ultra-finement broyé. Si on le pulvérise vers une flamme, il y a combustion direct. L’astuce est que le rapport surface/volume explose (en 1/r), donc la cinétique de combustion aussi.
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.

I'm not sure how many are aware that this is happening. But we should be extremely concerned about this. We should not be integrated with the Israeli military. As a matter of fact, we should've cut Israel off decades ago. But right now, it's imperative to Americas survival.✂️✂️ #SheShed
