Say hello to Gopal

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.

@notresz @freemo runs qoto.org has always given helpful and useful information with his broad range of interests

@p is also a very cool guy, runs FSE and, from my naive understanding, clued up in all things opsec and computing

they might not like being mentioned in the same breath but they're "big nodes" in fedi imo

Also worth checking out bitcoinhackers.org and others on qoto.org

strong shitposting/memework on FSE but I wouldn't expect tech insights from the majority there ;)

In 1930 the Indiana Bell building was rotated 90°. Over a month, the structure was moved 15 inch/hr, all while 600 employees still worked there. There was no interruption to gas, heat, electricity, water, sewage, or the telephone service they provided.

That's known as the "white savior". (Panel L3 in the graphic) The implication is that the relationship is asymmetrical. A textbook example from Hollywood is The Blind Side with Quinton Aaron and Sandra Bullock. (A film with a lot of other racial issues besides the overall white savior bias.)
