On the Conservation of Physical Quantities
Certain transformations of isolated physical systems underlying various conservation laws in physics are noted. As regards each of these transformations, there is a theoretical action that is equivalent to a matched physical action on the system. Evidence supporting this thesis is found in experimental psychological research where results of various experiments allow that the imagined rotation of an object is analogous to a physical rotation. The conservation laws based on the transformations noted are theoretical or mental in nature to the same extent that they are physical. When one of the conservation principles noted is tested by carrying out the relevant transformation on the system, this test is essentially one of the influence of mental activity on physical reality.
