In this garden, seeds were planted in a neat grid, but not all of them grew into flowers. Each seed cast a shadow in a straight line out from the center of the garden, and the seeds planted in the shadows did not sprout.
When the flowers were gathered, and the size of the harvest was measured, a factor of π appeared. I do not know why π came to this orderly garden, shaped only by straight lines. Perhaps it was attracted by the buzzing of the bees, as it is by all music?
