More work to follow, comparing this with the spire of a real seashell......

More work, 12/2/2015
Compare these, the theoretical, and the real. Almost exactly the same.
Three short spired and one long spired seashells.
One can make mathematical models by projecting the merged spiral up into cones of varying heights.
= next post!
