Quand j'étais une lycéenne, j'ai connu l'autrice de cet article. Elle est comme une étoile pour moi, parce qu'elle était la seule lesbienne que je l'ai sue qui poursuit dans le monde des mathématiques.
Je l'ai rencontré dans la vie réelle, dans une conférence mathématique. J'étais vraiment stressée, et je l'ai demandé plusieurs des questions bêtes.
Quand j'étais une lycéenne, j'ai connu l'autrice de cet article. Elle est comme une étoile pour moi, parce qu'elle était la seule lesbienne que je l'ai sue qui poursuit dans le monde des mathématiques.
Je l'ai rencontré dans la vie réelle, dans une conférence mathématique. J'étais très stressée, et je l'ai demandé plusieurs des questions bêtes. Malgré, elle ne l'a pas pensée bête, et elle m'a répondue avec plusieurs des détails.
Je fais plaisir pour lire son article, qui focalisé à la difficulté fondamentale de comprendre les mathématiques modernes et l'importance de repenser et recréer à la fondation de mathématiques.
Quand je la rencontrais, je ne pensais pas qu'y réexaminer est absolument nécessaire. Mais maintenant, je pense que c'est plus en plus irremplaçable. Pendant mon tour de math, je me manquais de conseil de la part de professeure. Alors c'est plus en plus difficulté de trouver et corriger mes erreurs.
Ces derniers temps, je me sens de plus en plus que, même si je comprenais les articles de pointe, je ne pouvais pas en vérifier les détails. Et ceux qui recevaient des conseils (principalement des hommes) évoluaient souvent au sein de leurs petits cercles, et échange d'idées dedans, ce qui rendait mon intégration difficile, et encore plus difficile de solliciter leur aide.
En lisant cet article, je me suis demandé si elle avait rencontré des difficultés similaires au cours de la dernière décennie, ce qui aurait pu l'amener à se repenser à la langue fondamentale de mathématiques et à s'intéresser enfin à l'HoTT.
“We need to focus far more energy on understanding and explaining the basic mental infrastructure of mathematics—with consequently less energy on the most recent results.”
Je devrais commencer à penser comme ça aussi.

Some people do not want to have sex and consider it rape. However, the system's people they all want sex. The system should keep the people in the system. The system should be just. They consider them innocent and the others guilty. But how. They all pretend to be the exact opposite and create fake evidence for the innocents.

There are undisclosed discoveries that are used as weapons against people who are considered to wake up people or prevail an opinion against others. This means that certain people you see as good and innocent might actually be the opposite, evil and guilty by secretly sabotaging innocent people to gain themselves the favoring of others.

Unlocking sudoku's secrets (2025) https://lobste.rs/s/zuib1a #math
https://chalkdustmagazine.com/features/unlocking-sudokus-secrets/
One thing I like about this book is its approach to eigenvalues and eigenvectors. Most linear algebra books present eigenvalues as roots of the "characteristic polynomial", which is built from the "determinant", which in turn has some formula defining it. These objects are rarely motivated geometrically, and so you're left with limited understanding of just what an eigenvalue is or why linear transformations on finite-dimensional vector spaces must have them. Axler avoids determinants till Chapter 9 of the book, focusing instead on linear operators. The fact that operators must have eigenvalues pops out of the observation that iterating an operator on a given non-zero starting vector results in a set of vectors that must eventually become linearly dependent. This fact also leads to the development of the characteristic polynomial; you can then come at the determinant from this, more geometric, perspective.

I never really got the jargon for “divisor,” “numerator,” etc. into my head… Basic stuff, I know. 
Subtraction: minuend - subtrahend = difference
Addition: addend + addend = sum
Division: dividend / divisor = quotient
Division: numerator / denominator = ratio
Multiplication: multiplier × mutliplicand = product
And now we both know! Never again will we get confused reading elementary math texts.

Introducing my latest project: Very Specific Numbers!
Inspired by sports jerseys with numbers on them, I've always thought about making shirts with very specific (or nerdy) numbers common in mathematics and science but not on clothes.
Until now!
Now you can walk around sporting Avogadro's constant, the largest known prime, or an utterly huge number like TREE(3). Enjoy!
