...Schrodinger's formula] at the page-top tells all-a new message in words old but not outworn. The mathematician reads it thus: "Schrodinger bases his theory on Hamilton's Principle, using as Lagrangian the square root of the negative of the determinant of the Ricci tensor...
Professor Elie Joseph Cartan of the University of Paris delivered an important paper on "The Extension of Tensor Analysis to Non-Affine Geometries." Speaking in French, bouncing with animation, gesturing with vehemence, this tanned, fox-bearded little man suggested a new mathematical approach to the great problem of a unified field theory which would embrace both the atom and the universe-a theory for which Professor Einstein has long been the No. i searcher. Roughly speaking, "non-affine" space is undistorted space. Dr. Cartan finds that some of the "vectors" with which Relativists play have a dual existence-in distorted...
