## ยง Geomean is scale independent

`sqrt(ab)`

is dimensionally meaningful even if `a`

and `b`

are dimensionally different. I found
this interesting, since it implies that Geomean is not "biased": arithmetic mean is more sensitive to large values (eg: `(1 + 999)/2 = 500`

),
while harmonic mean is more sensitive to small values. Geomean is neither, so it's more "balanced".
