periodicity

"These two opposing actions and reactions constitute the electro-magnetic oscillations, or compression-expansion sequences, which are present in every mass and which constitute the mechanistic or life principle of the universe. These sequences have a periodicity of preponderances which are first preponderantly generative and then preponderantly degenerative, which we know of as the phenomena of growth." [Russell to NYT - 1930 November 2]
