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.

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.

Interesting article about the bizarre life of mathematician Alexander Grothendeik
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!

Happy birthday to #mathematician & geodesist Gladys West (née Brown in 1930)! Shown with satellite tracks & 3 satellites important to her career: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. 🧵1/n

While general participants are welcome, I need the commitment of board-level founders.

A big shout-out to @gbhnews for another incredible podcast series! I'm midway through "Scratch & Win", which documents the meteoric rise of the Massachusetts State Lottery, and it's pure nerd catnip: organized crime, gambling, power, machine politics, combinatorics, computer science history! I can't believe the interviews they managed to get (and that the closing song is sung by the former state treasurer). All props to the production and editing team. Ian, Isabel, Lacy, and everyone involved should be really proud. Waiting for the inevitable HBO miniseries!

Quote from episode 1 transcript:
The Massachusetts Lottery had already rejected nearly twenty prototypes by the time they settled on a final design -- the one with the paper flaps. Only to have John Koza, this recently graduated wiz kid with a dimpled chin and a combover, show up and tell them it was flawed. So on the spot they made a deal. Koza could take home 50 tickets and do his best to prove they could be hacked.

The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.
\[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]
Inverse Fourier Transform:
\[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\]
The equation allows us to listen to mp3s today. Digital Music Couldn’t Exist Without the Fourier Transform: http://bit.ly/22kbNfi

This had me captivated for a good five minutes. I just kept watching how the patterns matched up, trying to parse out the connections in my brain.
Who knew an animation of a Rubik’s Cube and some corresponding concentric circles could be so stimulating?
I have absolutely no idea who created it. Tried to find out to no avail. (Happy to edit with a citation if someone knows.)
