An explanation I gave a while back as to why gun statistics generally favor the fact that less restrictive gun laws means fewer violence and homicides.

I basically explain why the typical argument of "countries with more guns have more violence" is inherently anti-scientific as it violates fundamental statistical analysis good practices. Instead we would use statistical causality tests for this, not correlation tests. When we actually look at the data from that perspective it generally shows that countries with less restrictive gun laws effectively lowers a nations homicide and violent crime rates.

Reattached the graphs from that post, but best to click the link to the original post where I go into more detail (the graphs are there as well).

I wanted to share a write up I did not to long ago explaining **circuit duals** with a specific focus on **magnetic circuits**. They behave the same as an electric circuit in the sense that anything you can do with an electric circuit there is an equivalent way to do it with a magnetic circuit. A magnetic circuit is a circuit that uses the magnetic fields propagating through "wires" rather than electric fields. It's a very cool idea and worth a read, though all the usual electric concepts are flipped, for example instead of talking about electromotive force (EMF/voltage) you would use magnetomotive force instead (MMF) as filling the same function as voltage in an electric circuit.

Let me know what you think, this tutorial was a week long effort to write.

I had forgotten about #somafm . I think I first found it back in high school (a charmed time for me). Looking at the site now, I think I even copied their CSS for my own silly #icecast music radio's tracklist back then.
