==introduction

• added an extra dimenstion to the three dimensions of space and in so doing, gave a unified description of gravity and electrodynamics
• two extra dimensions rolled up into a tiny 2-sphere
• three photonlike particles emerged
• each photon carried charge; it could emit either of the other two
