Bonjour Mastodon ! Une courte #Introduction après avoir passé un bon moment en observateur 
Je viens des #Maths appliquées, et continue à m’intéresser aux sujets liés à la tech, quand elle me semble politiquement émancipatrice : #LowTech, #DIY, #LogicielLibre, #DonnéesOuvertes, etc.
Au quotidien, beaucoup de temps passé à farfouiller de la #Musique, un peu de #Cyclisme et de la #Cuisine 
Mes pronoms : il/lui
---
Hello Mastodon!
A brief #Introduction post after some time as a fediverse observer
I come from applied #Maths, and am still quite interested in related tech topics when they lead to more freedom and emancipation: #LowTech, #DIY, #FreeSoftware, #OpenSourceSoftware, #OpenData, etc.
In everyday life, a lot of my time is spent digging (and sometimes playing) some #Music, a bit of #Cycling, and #Cooking
My pronouns: he/him
It is exponential.
Every second that passes is a smaller percentage of your life. You just do not notice when you are young, because the curve appears to be linear.
Odds? There are no odds.
Odds are division of probabilty and dividing by zero is not allowed.
**Descartes’ Mathematics**
“_In La Géométrie, Descartes details a groundbreaking program for geometrical problem-solving—what he refers to as a “geometrical calculus” (calcul géométrique)—that rests on a distinctive approach to the relationship between algebra and geometry._”

Bonus #Joke 1:
I saw my math teacher with a piece of graph paper yesterday. I think he must be plotting something.
Bonus #Joke 2:
Did you hear about the over-educated circle?
It had 360°!
(It's #HootinTootinTuesday again! Post some jokes or funny memes under this hashtag today, and bring lots of smiles to #Mastodon.)

I hear you.
My favourite (perhaps less jarring?) example is when a court declares they have found someone guilty, and that their threshold of guilt is "on balance of odds".
I look at the lawyers and the witnesses and realise that none of them has studied actuarial or probability mathematics. I wouldn't even trust them to understand a bet on the horses. For a scientist to watch them is like observing a cargo cult. Worse, I am sure, is for a scientist to find themselves on the receiving end of such a court.
I would offer the meagre consolation that you can see the feedback loops that drive them to behave so, where they think themselves to have free will.

PX & PY are the coordinates of the center, RX & RY are the values of horiz and vert radius
If you are curious as to how the Trump Advisors crunched the numbers to arrive at the highly publicized freedom day tariffs watch this 9 minute explanation. Obviously the Office of the President has minimal respect for the intelligence of his supporters and most other educated people. #tarrified #maths https://youtu.be/PWhv-06DNjE?feature=shared
I have posted the 238th Carnival of Mathematics!

If I missed something please let me know.
There is an extremely slow bit of javascript for untouchable numbers that hopefully won't make the post untouchable.
Thank you @aperiodical for organizing this.
This month we have posts from @mjd Peter Cameron, @two_star, @j2kun, Brian Clegg, @fortnow @KarenCampe, Amédée d'Aboville, Ed Vogel, @standupmaths
There was also an amazing amount of math and art being shared on blueSky with @Ayliean 's math art March prompts
Those tariff numbers from the original tweets.

No, officer. I looked at my gps and became aware of my exact location.
**The Secret Formula: How a Mathematical Duel Inflamed Renaissance Italy and Uncovered the Cubic Equation**

**Generative AI and accuracy in the history of mathematics**
“_This process is illustrated by querying ChatGPT with questions from a history of mathematics quiz designed to highlight the common occurrence of mathematical results being misattributed. ChatGPT's performance on a set of decades-old common misconceptions is mixed, illustrating the potential for these systems to reproduce and reinforce historical inaccuracies and misconceptions._”

**Born On This Day**
Mathematician, astronomer, and physicist Pierre-Simon Laplace was born in Beaumont-en-Auge, Normandy, France on this day in 1749.
“_He proved the stability of the solar system. In analysis Laplace introduced the potential function and Laplace coefficients. He also put the theory of mathematical probability on a sound footing.”
