Reading a biography of Emmy Noether and I'm so furious how she and other women in STEM have been treated. Shame on Prussia and all the men in science holding her back at every stage, omitting her name in publications and not even paying her for her job!

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

I've seen this video a couple of times, but I never saw any explanation.... so I decided to work it out for myself how they did that! 🙂 Feel free to watch it and see if you can work it out yourself, but if you can't (or don't want to), then here's how this works (scroll down for reveal)...

First some pronumerals, then the steps - a=97, b=94, c=3, d=6
- c=100-a
- d=100-b
- the first 2 digits is a-d
- the last 2 digits is cxd

I'll be posting the questions from AMS 2025 Daily Epsilon of Math Calendar daily from now on. I should have started earlier (doing it on Blue sky for some time). Hope it will be of interest

Here's the question for April 13th. For those unfamiliar with the calendar, the answer is always the day of the month. Looking for imaginative solutions is the aim.

The mean of: •x and 9 is w • 2x and 15 is y • 3x and 18 is z • w, y, and z is 20

The polyhedron, a ‘Catalan’ solid, has 24 identical kite shaped faces, 26 vertices and 48 edges. #maths #mathematics #math #polyhedrons

Deltoidal icositetrahedron coloured blue, displaying grid lines and axes and set against a black background. The polyhedron is made up of 24 kite shaped faces with long edge length 0.9142 units and short edges 0.7071. The distance across opposite vertices is 2 units.

Je partage ce texte [1] d'Eva Philippe [2], sur la place de la recherche en mathématiques, sur le militantisme, sur la dissonance cognitive, sur la recherche de sens à nos vies, sur l'enseignement (des mathématiques), sur plein d'autres choses aussi.

J'ai trouvé ça beau, honnête, humble, puissant.

Counting Is Hard

Hear me out. Mathematicians should adopt Futhark (en.wikipedia.org/wiki/Runes#Fu)

Mathematicians want new symbols like magpies want shiny things. Runes have the advantages that

1. There are not too many of them at around 24 depending on flavour.

2. Many of them correspond to a latin character in a relatively straightforward way, allowing for an additional "sort" of variables per context.

3. They can be drawn with straight lines in a way that is clear at a range of font sizes and are forgiving to those with poor handwriting (I'm looking at you, ξ)

4. They come from a dead language, so who's going to complain other than old norse specialists.

This handles many of the disadvantages of say:
Chinese characters (too many, and I know over 2000)
Hangul / Kana / etc. (multiple sensible choices for a given consonant)
Hebrew / other abjads (none that correspond to vowels)

Some problems:
1. Basically none of you know them. Consult your local tiktok fortune teller for a brief intro

2. The standard futhark order does not really correspond to latin/greek order

Edit: 3. Poor font support for Runes. They are at least assigned standard unicode codepoints in the Runic block, so this could be mitigated over time. In tex there is the "allrunes" package at least, although I have never tried it.

(This isn't a shitpost, I've brought this up at least four times this week already at MGS)

Numbas

We're running one of our regular community drop-in sessions today, 09:30 - 11:30 UK time.

This is an opportunity to have a chat with the Numbas development team and other members of the community about anything to do with Numbas. You could learn more about Numbas, ask for help writing questions or deploying Numbas exams, talk about what you’ve been doing, make a feature request, hear what we’re planning to develop next, or just hang out with us for a while.

To join the session and for a calendar of upcoming dates, go to numbas.org.uk/drop-in/
