I am always loathe to get into these things but when there appears to be a
lack of understanding of math then I want to try to correst it. In volume
measurements the radius appears as the cube, the third power. Thus a
diameter of 5 (radius 2.5) gives 15.625 while a diameter of 7 (radius 3.5)
42.875. As you can see, the latter number is approaching three times that
of the former. thus the weight of the latter should be roughly three times
that of the former. wish that I could get to St. Louis to see this A.
titanum when it does bloom.
