Abstract
THE present time appears particularly appropriate for an attempt to form a complete picture of our knowledge concerning matter and energy. Starting from the early controversies fought around the question of continuity and discontinuity, the author describes the origin of the atomic hypothesis, the idea of chemical elements and their periodic classification, and the methods of determining Loschmidt's or Avogadro's number. This is followed by an account of the properties common to all chemical elements, a history of the atom and of its spectral manifestations. The essential features of radioactivity, radioactive elements and isotopes are set out in an easily intelligible and attractive form. Throughout the book are scattered many historical data, useful formulae and illustrative numerical examples. Particular praise must be given to the line diagrams which are, with few exceptions, models of clearness.
