Two New Worlds (1) The Infra-World; (2) The Supra-World

Abstract

THE first part of this book is an elaboration of an analogy already familiar to the scientic public. The Infra-world is a universe in which an earthly atom is a solar system: the positive atom is its sun, the electrons are its planets. The author points out that the scale of distances in our own and the infra-world is approximately in the ratio 1022:1, this being the ratio of the average diameters of our solar system and an atom. Further, the infra-year, measured by the period of revolution of an electron about its positive atom, is, for a particular case, reduced by the samr factor. In this coincidence Mr. Fournier finds justification for regarding the world of atoms as a veritable universe on a smaller scale.
