General Relativity states that matter generates "curvature" within the vacuum of space surrounding it, and that this curvature gives rise to inertial force and gravitational attraction amongst objects. The Electro-Gravi-Magnetics (EGM) method, described in the Quinta Essentia series, greatly enhances our understanding of the phenomenon of curvature. EGM is an engineering tool which systematically reveals the common thread connecting GR, Quantum Mechanics and Electromagnetism. Via this connection, one may represent space-time curvature in quantitative terms. The unique "universality" of EGM makes it a highly valuable and versatile tool for use in varied fields of physics. It also provides a practical framework for investigating "space-time metric engineering" concepts such as the artificial modification of gravitational fields and faster-than-light propulsion mechanisms. Part One of the Quinta Essentia series presents the layman reader with a conceptual introduction to the EGM method.
