CanadianAnimalI remember vaguely that JS-Research discussed copper and other pm with regard to TUD in one of his articles with some interesting numbers. I can't remember which one and if it was a german or english version that I read.
Does anybody here recall that? Alpha perhaps? I will try to find it.
Fordster, as usually, is right: Take good care and don't let the bunch of malevolents spread doubt "by just asking question": Are you sure the earth isn't a disk?
Best wishes to all who deserve to be long
