🎓 Doc Freemo 🇳🇱 @freemo@qoto.org

@snder Hey noticed a year ago you requested access to the Aparapi group on qoto's git but i never saw it so i never granted or rejected.. any reason you want access, all the repos are public? access is usually for moderators or contributors. were you looking to contribute?

Holy crap just realized the blog article I wrote is 63 pages long. I wrote a damn book :)

For those of you who enjoyed my recent blog post on Circuit Duals and Magnetic Circuits I have now compiled a version of it in PDF if you want to keep a local copy or have it for reading on on an e-reader. Feel free to distribute the link.

For those of you who are just now hearing about it the article describes the idea of Duality in math, how it applies to circuits, how to calculate duals for systems of equations, and a few examples of circuit duals. It also goes indepth on magnetic circuits as a dual of electric circuits. There is an interesting blurb at the end about how to extract energy from permanent magnets as well.

If you prefer the more colorful blog link instead, which will also be the only place I make corrections or update it most likely, the link for that is as follows:

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.

So seems halve of you guys got this one right, 28% got it wrong, and 16% of you are smart asses.

You all did better than I'd have expected :)

Evolution always seeks to create a population such that its goal is the proliferation of that species in the short term (in evolutionary terms) with no regard for the future.

Moral conscience is only beneficial to a species when the species exists globally such that there are little or no free resources. Only then is the greater good more beneficial to the survival of the species than the individual or the good of the pack/tribe over another pack/tribe.

However on the flip side intellectual evolution is an advantage even in very sparse populations with plentiful resources. Greater intelligence means you can harvest and utilize those resources more quickly and put them to use growing your family or tribe as well as defending it.

As such due to the nature of evolution moral evolution is doomed to always lag considerably behind intelligent evolution. Furthermore since evolution is, in human life span terms, a very slow process, it isnt something that should be expected to catch up until many generations, and a lot of death has passed first. Due to the nature of intelligence to enable us to find more effective ways of killing ourselves this can inevitably lead to a species destroying itself long before its moral evolution has a chance to balance the equation.

It is this reason that many scientists speculate why we dont see very many radio signals in space indicating alien intelligent life, the theory goes that the very nature of evolution is such that life will almost inevitably destroy itself once it reaches the intellectual singularity before it has a chance to become interstellar and as such simply doesn't have a very long time span where it exists in a state where it gives off radio waves.

Sadly we dont appear as though we are going to be much different in that regard.

Man is a rope, tied between beast and overman--a rope over an abyss. What is great in man is that he is a bridge and not an end: what can be loved in man is that he is an overture and a going under...

I say unto you: one must still have chaos in oneself to be able to give birth to a dancing star. I say unto you: you still have chaos in yourselves.

Alas, the time is coming when man will no longer give birth to a star. Alas, the time of the most despicable man is coming, he that is no longer able to despise himself. Behold, I show you the last man.

"What is love? What is creation? What is longing? What is a star?" thus asks the last man, and blinks.

The earth has become small, and on it hops the last man, who makes everything small. His race is as ineradicable as the flea; the last man lives longest.

"We have invented happiness," say the last men, and they blink. They have left the regions where it was hard to live, for one needs warmth. One still loves one's neighbor and rubs against him, for one needs warmth...

One still works, for work is a form of entertainment. But one is careful lest the entertainment be too harrowing. One no longer becomes poor or rich: both require too much exertion. Who still wants to rule? Who obey? Both require too much exertion.

No shepherd and one herd! Everybody wants the same, everybody is the same: whoever feels different goes voluntarily into a madhouse.

"Formerly, all the world was mad," say the most refined, and they blink...

One has one's little pleasure for the day and one's little pleasure for the night: but one has a regard for health.

"We have invented happiness," say the last men, and they blink.

-- Thus spoke Zarathustra, Nietzsche

Ok I think my article will be ready to be published tomorrow after I do one more re-read in the morning.

In the meantime I'd really appreciate anyone giving it a read and seeing if they find any errors please. I really could use some final eyes on this before I publish it live!

@Gargron Hi gargron, hope your well.

A user of mine who deleted an account asked me to undelete it as they want to come back and have the same username.

When I looked it up on the internet it seems tootctl can technically do it but people warned it could corrupt the database.

Do you know the safest and easiest way to do this, if it is doable at all?

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:

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.

I have been writing a blog article that is getting so big its a small text book at this point. Easily the biggest and more detailed blog article on a subject I have ever wrote.

The topic is Duals of Electrical circuits.

It takes me half the paper to even get to electronics, I start by trying to describe what a dual is in general terms, give simple mathematical examples, then go onto duals of systems of equations where I finally tie it into electrical circuits.

At that point I dive into a series of examples of different types of duals for electrical circuits, and then finally end with describing a magnetic circuit as a dual for an electric circuit, where the power sources become magnets, the copper wires are replaced with iron ones, electrical current is replaced with magnetic current (which is a propagating magnetic field), and then I explain each magnetic dual for each discrete component like capacitors, inductors, resistors, and transformers. Needless to say this thing gets really deep really fast.

If your interested in seeing the final result keep an eye out on my blog, should be released any day now.
