Really? I clicked through and was wondering what weird and interesting mathematical twist I'd read about, and it turned out to be "well only a few people believe it, and they happen to live in Japan".
Yeah, exactly, me too. I was expecting something about Japan using 50 and 60 Hz at the same time, something about counting in units of δΈ‡ instead of 1000s, some WWII story, heck even some Fukushima one, but instead it was just something akin the Kirisuto no Hata (the belief that Jesus ended up in Japan by some).
