I think you are right on limited consequences of a fire. I would expect though that an ignition source should be pretty easy to find in a car accident: the exhaust systems of all involved cars are likely got enough.
Then Japan didn't really acquire the writing system from China. The grammar is iiuc very different, and at some points in history characters were imported for the pronunciation, ignoring their meaning.
I think this isn't true without some additional qualification? After all, all petty crime, vandalism, littering, aimless churlishness etc. is against social norms. I think I get what you mean though, but am also missing a term for that kind of social norm contravening.
My vague recollection is that there was oneish root of ideograms, but the languages evolved before writing in an unrelated way. I don't know how much adoption of writing affected the languages.
@freemo Roots of the language and of the writing system are not necessarily the same. There were multiple instances of significant import of "characters" from ~Chinese into Japanese and I had the impression that at least some of them didn't import much past the characters themselves.
@freemo Ah, then it's quite likely that it was indeed before then. I'll then notify you again if it reoccurs, and otherwise will assume this was a result of the issue at that time.
Also, my own post does not appear in my home timeline (or rather, appears but then disappears upon refresh). That suggests something is still broken, and that we're not dealing just with an aftereffect of something.
People use (I don't know how successfully) gravimetric anomalies to supplement inertial navigation underwater (in a similar mode to those early car navigation systems that could never locate you, but would use their knowledge of how the roads look like to correct dead reckoning). I wonder if this could be used in a similar way.
BTW I wonder how many sports trackers use the magnetic field to simplify their motion tracking, and then work very differently sufficiently far north or sufficiently close to the equator. (E.g. for breaststroke in swimming pools oriented east-west in Switzerland keeping a running average of the magnetic field direction at wrist is a more reliable way of counting lengths than what Garmin was doing up until something like 1-2 years ago)
I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work in infosec, am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I'm being inaccurate. I think that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.I appreciate it if my grammar or style is corrected
