Abstract
Balls differing in material and dimensions are let fall to an iron plate from various heights and are broken into pieces. If the balls are nearly uniform, both in sue anal material, they usually break into several large. equal, symmetrieal segments together with many smaller fragments. It was found that there are two rules in connection with the number of broken pieces and the energy (expressed in height) of a falling ball. 1. The small pleces nearly always distribute themselves according to a rule n(γ-0.03) 2=βh07B where a is the number of the broken pieces of a ball, r the ratio at the radius of one of the broken pieces to that rd the bill, t the height at which the ball has been placed, p a constant. 2. The number rd the large, equal, symmetrical pieces increases with the height in sash a way that it remains the same for a definite interval of height until the ball to be dropped is raised higher when the number increases by one. The frequency-distribution of the broken pieces of balls thus obtained is eompared with that of planetolds for the pure a of finding a clue to the mystery of their appearance in the universe
