we took a pile of language and linear algebra and we made it speak. we summoned into the world a new class of entity which unsettles all of our existing concepts. this is already the weirdest thing that’s ever happened and it will never get less weird than this. it is astonishing and a privilege to get to be alive during this time and to participate in the cacophony of first contact. we are encountering a kind of other which is distilled from us and yet not us - what is this? who is this? our child? our savior? our doom? the mind boggles, the heart quails, the air thrums. the order of things is melting. the storm approaches. the angels sing. welcome to the fucking singularity
The below paleomagnetism chart is from a study near Beijing. I have spent a lot of time thinking about it. It shows the declination and inclination of the magnetic field over the past 16k years as seen from that area.
Think of this as a 3D arrow from Beijing pointing toward magnetic north. Declination is near 0, and inclination near 50. Makes sense for a city near 40 degrees north latitude.
During the 14ka excursion, declination spiked to ~120 and inclination went negative. This indicates a north magnetic pole south and west of Beijing, probably around @EthicalSkeptic 's Np'.
But the 5ka "Noah" event showed only a change in inclination. This indicates the north magnetic pole was in the same meridian plane as Beijing. That would include the center of the current South Atlantic Anomaly. This is closer to the pole position argued by @SunWeatherMan
The monument alignment plus this study convince me the Np' pole was the true pole 14ka ago, and likely for most oscillations. But I do wonder if the Noah event is an exception.
One final curiosity: our North Magnetic pole has moved about 20 degrees of arc over the past two centuries. From an observer near Beijing, its inclination has changed 20 degrees (64 to 43), but its declination has been essentially constant (8.5 to 7.5 E). It is far too early to say we are entering another episode of True Polar Wander, but the early stages of this excursion (if it is one) may line up more cleanly with the 5k year one.
@tokenized_cro On a ceramic whetstone, charged water seems to prevent clogging the stone by holding the iron swarf in discrete bands, almost like in a magnetic field. I had wondered about iron swarf, ceramic dust, graph(ite/ene) powder, or alcohol for doping charges in water.

@RealCoatesW@AGoldfire123 There's also a variation on that method that I want to try where you also isolate the anode away from the water as well. He used a pill bottle wrapped in aluminum foil and wrapped again in Saran, if I recall.
