@derspiegel_de soviel Offenheit finde ich gut.

Ich schickte ihm, bzw. seiner Stiftung, vor einiger Zeit mein #Script, erste 40 Teile. Was hat er damit gemacht?! :mastosob: #CRISPR_rEvolution #fff #Hirschhausen #Netzfrauen #Endocannabinoide #Medizin #Homöostase #Mechoulam #Janov #Sucht #EndokrineDisruptoren #Trauma 😃 #blablabla...?

Voi vi sentite più traditi da un ministro dell'ambiente di vera destra che fa gli interessi degli industriali o da un ministro dell'ambiente di finta sinistra che fa l'amicone con gli ecologisti ma poi si perde nel #BLABLABLA, riesuma il nucleare e finanzia i petrolieri?

Fluency in math

Fluency in language is relatively easy to measure: you can give a talk, keep up in a coversation and write jarry, more or less gramatically coherent texts. Math is trickier: most people struggle with it, some people seem to be better at it naturally. I have no idea why is that the case, but there is an interesting observation.

Math is language we describe universe with, because words aren’t suited well for this purpose. There are a few major concepts that are tough to describe in plain language, like limits in calculus and tensors in algebra. And math is a weird language, mistakes are punished way more than ever, infact, one wrong symbol renders the entire “text” meaningless. This breeds frustration.

Fluency in math, in a particular parts of it, consists of two things. Firstly, the ability to derive new relations and transform existing ones effortlessly and without mistakes. No, there is no “I know this, I’m just so inattentive” when you skipped a minus sign. Mistakes show gaps in either knowledge or skill, they are a signal for you to get some more practice.

Secondly, the internalization of concepts. It boils down to the Feynman rule: you only understand it if you can explain it. The only way to internalize a concept is to link it to existing knowledge: think of the knowledge as a map, and your competence grows in a tree-like shape all over it, creating nodes and lines. As long as there are enough nodes near something new, you can learn it. If you struggle - roll back and explore the area around, maybe go slightly sideways or practice what you already know.

la blague du jour : entendre Mounir Mahjoubi venir pleurer sur les plateaux contre #Amazon
😂

"Amazon c'est pas bien, c'est des méchants, le numérique détruit des emplois, les GAFAM ne payent pas d’impôts...." #blablabla
C'est pas tres #StartupNation ça Mounir :)

le mec est a 2 doigts de découvrir le capitalisme et le néo libéralisme. Et le numérique à priori il découvre aussi :)
"Moi j'achète mes livres en bas de chez moi" qu'il nous explique le camarade bourgeois.

@Shinra Avec plusieurs voisins on a envoyé chacun une lettre en AR selon le modèle ici:
artemisia-lawyers.com/fran%C3%

On a tous reçu la même lettre qui ne répond à aucun de nos arguments et demandes et qui se contente de répéter les mensonges habituels: c'est obligatoire, ça vous fera faire des économies, #blablabla

S'ils m'appellent je dis que je ne veux que des lettres, histoire d'avoir des preuves écrites. Pour l'instant aucune nouvelle. Heureusement mon compteur est à l'intérieur, à l'abri.
