Revolut°Permanente🚩 « Concrètement, c'est pour affiner les rangs » : À Aix-Marseille, la réforme de notation accélère la sélection: Cette année, un nouveau système de notation, via des « blocs de compétences », vient durcir les conditions d'obtention du diplôme et augmente le stress étudiant. Un bouleversement volontairement opaque qui vise à accélérer la sélection.Jeunesse / Sélection à l'université /… revolutionpermanente.fr/Concre 🚩RP #Éducation #Université #RéformeÉducative #Étudiants #Notation

TIL: "The use of the symbol ∈ (a stylized form of the Greek epsilon) to denote membership was initiated by the Italian mathematician Giuseppe Peano in 1889. It abbreviates the Greek word ἐστί, which means "is". The underlying rationale is illustrated by the fact that if 𝐵 is the set of all blue objects, then we write "𝑥∈𝐵" in order to assert that 𝑥 is blue."
- Enderton, Elements of set theory

Every now and again I get annoyed that we write the name of the function before the thing it's applied to.

I'd like it the other way round, so that as you read left to right, you read the story of what happens to the input value.

To evaluate 𝑓(𝑔(𝑥)), I have to scan all the way to to the right, then work my way back to the left, first applying 𝑔 and then 𝑓 .
I'd prefer to read ((𝑥)𝑔)𝑓.

"But it's called 'f of x'," you cry.

Yeah, but it doesn't have to be, pal!

Why not "x's f"?
