Ils sont fous ces savants

..pas moi:heu: :(
 
Tourne toi, je vais t'expliquer...
 
Devant la stèle dédiée à Pluton, sur le Mall, la grande esplanade de Washington, les condoléances s'accumulent. Une carte est adressée à l'ex-neuvième planète du système solaire. Elle est signée de Mars, Jupiter, Vénus, Mercure et les autres : "Tu vas nous manquer."
Le reste de l'article.

Et pour la bonne bouche, sa conclusion, portée par un adolescent :"Mais pourquoi ils ne la font pas sauter, tout simplement ?"

:D:D
 
"Tout ce que je sais, c'est que je ne sais rien"


Donc ce qu'on nous bourre dans le crâne depuis toujours est FAUX!? super!!! :mouais:

On vous fait apprendre bêtement par coeur des choses qui sont en fait, plus tard, complètement remises en causes! :rolleyes:

Il vaut mieux se rappeller ce que disait Socrate...On ne peut jamais être sûr de rien!

…that everyone wants to know: How do you take a shower in space? How do you brush your teeth? How do you wash your hair?
Well my friends, I must admit keeping good hygiene in space is not easy! There is no shower or faucet with running water. Water does not “flow” here, it “floats”

— which makes it a challenging act to clean yourself. So what do people do up here, specially the ones staying for six months at a time…? They improvise!

There are wet towels, wet wipes and dry towels that are used for cleaning yourself. Usually each person gets a wet towel a day and couple of dry ones. Each person has a personal hygiene kit where they keep their stuff like toothbrush, shaving kit, creams , etc. I got Dice-K’s kit so it had a razor and lots of shaving cream, but no makeup

Now brushing your teeth in space is another joy. You cannot rinse your mouth and spit after brushing, so you end up rinsing and swallowing. Astronauts call it the fresh mint effect

The most interesting experience — or I should call it experiment — is washing your hair. Now I know why people keep their hair short in space. You basically take a water bag and slowly make a huge water bubble over your head and then Very Very Gently, using a dry shampoo, you wash your hair. At the slightest sudden movement, little water bubbles start floating everywhere. I’ve made some video of my hair-washing experience that I will share when I return

Of course water here is a valuable resource, and is recycled so anything wet is not thrown out, instead it is left out to air dry. There is a water conduction collection unit that takes the moisture out of the air and recycles and purifies it. This includes your sweaty clothes after exercising. One of the cosmonauts once told me, “We are all very close to each other, we are like brothers and sisters, it is very unique because we drink each others’ sweat.” Now I know well what he means…
