yeah, I should have guessed that. ;)

as others pointed out, the geometrical methods primarily use ratios and the constant wouldn't come in. it is interesting to imagine how one *might* estimate it, given only materials available in Newton's time. clearly, if he felt no need (his methods produced useful results without needing it), it is likely he never estimated the quantity.

thanks everyone!
