   Nor do I know what "information" is, but just that they don't either. There is   
   nothing private about my questions, except the answers. As I mentioned,   
   Szilard was trying to find    
   a new dimension of physics, and if you look at what physics uses as their   
   fundamental units, mass, energy, space, and possibly entropy -    
      
   Ain't no *possible* about entropy, it's as real as energy.     
   Isn't that the point, information is entropy.

   and decay time of an led? It's an accepted rule of measurement that rise time   
   time is directly related to Band Width. (at least I hear it with   
   oscilloscopes.) So, I have to    
   review your paper on paper on circuitry to increase the BW of the photodiode.   
   It's an amazing paper, not least for the fact that this approach was   
   overlooked in a fairly mature field. I have to re-read it and ask questions.   
   So my question is: For the led,   
    is there any circuit approach to increase their BW? Or is this a wrong track   
   of thinking? (ie works for a PD, but a LED another matter entirely.) And a   
   corollary question: Once you have a fast blinking light source and fast data   
   collection. (Say ADC at    
   1 MSPS), is there any SNR-type advantage there?    
      
   I'm confused by what you mean by BW??  The optical BW (nm's), or decreasing   
   rise/fall times
