 that theory be true, we are dealing with those 

 situations in which matter and energy have 

 been differentiated to that extent where they 

 are no longer convertible into each other, 

 and they have no common factors. Instead 

 of considering matter and energy as the same, 

 it would appear to be preferable to consider 

 energy as an ultimate fact, and matter as a 

 product of energy. Whatever produced or 

 created matter must have been energy, be- 

 cause only energy can do things. If energy 

 ever was created it required pre-existing 

 energy to do the work of creating. 



The first fundamental fact or principle of 

 energy is that, while it may go through end-

 can be neither increased nor diminished in

 created or annihilated. This principle is 

 known as the "Conservation of Energy." 

 The "first law" of thermodynamics is 

 founded upon this and is simply a statement
