Cette semaine 1ers étudiants cas contact de l'année universitaire, donc 1ères séances d'enseignement de l'année en urgence .... mode d'emploi :

▶️on partage la séance en visio avec
▶️la prise de son est assurée par un pod (qualité excellente, aucune contrainte de distance)
▶️ et on envoie régulièrement une photo du tableau sur un chat pour permettre au étudiants en distanciel de mieux intéragir
👌

Aujourd'hui TRÈS gros morceau, on va parler du «peut-on rire de tout» sans citer Desproges, de cancel, de radicalité, et on essayera de pas trop se faire d'ennemis? Allez, on teste? Prions pour Pico de Chocapic (de quoi?)

Mais il est possible de dessiner d’une toute autre manière… Avec un peu de #mathématiques, et en quelques lignes de code, on peut réaliser de très jolies #fractales !

Avec #GpxTrackPoster (github.com/flopp/GpxTrackPoste) je peux représenter mes sorties running de façon esthétique et j’obtiens en bas un calendrier dont les jours changent de couleur en fonction de la longueur de la sortie. Ça ne serait pas simple mais j’aurais vraiment aimé adapter mes sorties pour obtenir un pixel art sympa 😁

So two weeks working on this article about Circuit Duals and Magnetic Circuits and it is finally finished and published! Check it out!

Its about mathematical duals and how they relate to electric circuits. I cover several common circuits as duals and how to calculate duals. Bu I also describe a rarely known type of circuit dual called a magnetic circuit that uses the magnetic field instead of an electric field to do all the things an electric circuit can do and explain magnetic inductors and capacitors. It's pretty cool stuff, I even touch on how you can extract energy from the magnetic field of a permanent magnet to power a magnetic circuit (or an electric circuit for that matter.

Help! From anyone interested in English, Physics, Math, or Science.

I have written a rather massive article in the hopes of teaching people with mid-level knowledge in electronics about the idea of Duals in mathematics, how that applies to circuits and the various types of circuit duals that exist

I also include a great deal of detail in the end about one very obscure and rarely studied circuit dual called the magnetic circuit dual, it is a circuit, like a magnetic circuit, but instead of current being the flow of electrons, it is the flow of a magnetic field through wires made of iron instead of copper.

I even touch on briefly how one can extract energy from permanent magnets and other details most people arent very familiar with.

The problem is the article is massive and I really could use some eyes on it. Whether its just to try to help me catch english mistakes, or if your not that experienced perhaps tell me the parts that are confusing, as I would like this to be accessible to people who may not be scientists and only know entry level electronics or science. any feedback from anyone at any level would be highly appreciated.

Keep in mind I couldn't find many good sources laying out the equations for magnetic circuits very clearly so I had to derive a lot of the equations myself, though the concept is well established as fact and many peer-reviewed papers have been written on it. But bear in mind there may be minor errors in my math as well, so that too needs some criticism, though the math should be fairly close to correct.

Anyway any input from anyone would be much appreciated.

The draft of the article can be found on the beta site for my blog, here is a direct link:

Similarly if you find any mistakes you can message me here, or you can leave a merge request on the repo for the article, here is the direct link to the markdown file in the source for my blog:

git.qoto.org/freemo/freemo-sit

It is much prefered that if you have specific edits like english or math you do it as a pull request as it can be a huge pain for me to hunt down the specific part of the text you are referring to if you point out mistakes as replies here. However if your unwilling to do a merge request please still ping me here as I'd rather know than to just let it go unnoticed.

Anyone who helps I will add a thank you with your name and a link to your own site at the bottom of the article if you wish, this might help draw some traffic to your own site.
