A another nonsense from synergetics, Kirby said that the cube of R = radius is the edge of the vol. of his unit tetra. so to Kirby very close is close enough. I thought math was considered a EXACT science but than what do I know, I'm a bad speller, have a accent, have videos no one understands but than who does understand synergetics, He just said Alan is confused, Steve is confused, I'm confused, and tons of folks left synergeo in droves are all confused, so who is not confused ? if one would like to shift through tons of synergeo posts one would see every EXPERT on synergeo has a different opinion, so please folks just introduce synergetics in to American curiccula as if America is not already one of the worst in education world wide 27th place from 32 world wide selected counties in math. and science, well than let's do it let put for all it's clarity lets put synergetics geometry in to a already damaged education system let's see what hapens.
