   clean signal. An overall average will include the noise as well.

   Dear Mikko,   
   Phil may be too smart to swing his weight around like that, did that occur to   
   you? On a personal note, I will tell you how to free your mind from its   
   shackles, so that neither an AK47 pointed at your head, nor Richard Feynman in   
   person, nor anything at    
   all will bother you in the least. You will know who you are, and have personal   
   power. However, I'm not interested in endless debates.   
   How do you like Finland? I have been impressed with the several scientists   
   from Finland I have worked with.   
   take care   
   JB
