 Feedback Is For  Making  The  Process  A 
 Whole  Lot  More Messy,  To  Introduce A 
 Fractal  In The  Spice  Mix... Things Or 
 Populations Of  Things  Start To Be Self 
        Referential Or Self Eating        
 (AutoVore...)  Or SpiralIng In Or Out... 
                                          
 In  The Sixties They Did Research In The

 That  Feedback Does  Not Give Rise To An 
 Equilibrium. They  Were Trying  To Prove 
 That Nature Is A Tame  Beast.  But She'S 
                   Not!                   
 This  May  Hold  True  Out There...  But 
 Maybe Not In Signal Wizardry?  Depending
