In order to account for all physical phenomena it was found necessary to add further terms to the metric structure of space and that this still left the interpretation of physical laws in a duel state. This had led him to look for a general metric-structure of space which would account for all phenomena. This problem, he thought, he had nearly solved. That would complete one great portion of the work that had occupied physicists for the last centuries since Newton. Beyond this , however, he also wished to derive from the modified equations, the elementary particles of matter, namely, protons and electrons.
Space is the primary phenomena and matter is derived from it as a secondary result.
Space is now turning round and eating up matter. It has formed a bridge between geometry and physics. That was, that they could also compare these two elements in the matter of direction. This idea came to him during a serious illness two years ago. The Professor acknowledged his difficulty in regard to the single equation to represent all phenomena.
