a mechanism wliich conforms to this relation, it follows from (7) that its 

 energy will vary as - . Expanding in the usual manner we then have 



W = WoC^ - i WoF2 + • • • 



This says that a particle represented by such a wave pattern would have 

 a positive rest mass and a negative inertial mass. Its momentum is directed 

 oppositely to its velocity, and energy must be taken from it to set it in 

 motion and given to it to stop it. Such a particle, when bouncing back and 

 forth between two rigid walls or rotating about two centers of force, would 

 exert a force tending to draw them together, instead of the usual repulsion. 

 It is interesting to speculate that if, in an atomic nucleus, the positive charges 

 which are passed back and forth between other nuclear particles were 

 associated with particles of this type their motion would exert a binding 

 force on the other particles. 



Conclusion 



It appears, then, that the ether model is capable of sustaining wave 

 patterns the behavior of which is qualitativ'ely in agreement with the 

 results of experiment. In order to establish fully the sufficiency of classical 

 mechanics for the physical description of natural phenomena, it will be 

 necessary to work out the complicated quantitative relations whereby the 

 constants of the ether may be deduced from experimental measurements. 

 However, until a serious attempt to do this has failed for some reason other 

 than sheer mathematical complexity, the insufficiency of classical mechanics 

 can scarcely be argued. 



In conclusion, I wish to acknowledge the contributions of those of my 

 colleagues who, through discussions over the years, have helped in develop- 

 ing the concepts which have been put together in the above picture.
