recognition of the possibility of the analytical separation of the general motion of a fluid into mean varying motion, displacing momentum, and relative motion, without mean momentum; and this suggested the possibility that the medium of space might be granular, the grains being in relative motion, and at the same time being subject to varying mean motion. And this has proved to be the case.
At the same time it became evident that it was not to be attacked by any method short of the general equations of a conservative system starting from the very first principles; and it is from such study that this purely mechanical account of the physical evidence has been obtained.
Apart from the introduction the analysis is effected in sections II to XV.
II. The general equations of motion of any entity—axiomatic.
III. The general equations of motion in a purely mechanical medium, i.e. a medium in which the energy is purely kinetic, which can only be,
| 1. | empty space. |
| 2. | perfect fluid. |
| 3. | perfect solid. |
