  1. Second law is statistical.. It is possible for something weird to happen, but the probability is astronomically small.
  2. Real world complication example: how willing the buyer is willing to pay a given price will strongly correlate how well the care is running.
  3. Another approach cos(x)=sin(90-x), so cos(90)=sin(0). In a right triangle, it is obvious sin(0)=0.
  4. You have assumed the buyer's "satisfactions" are independent, which may not be true.
  5. Question seems premature. Exomoons have yet to be discovered. The description of habitable applies just as well to exoplanets.
  6. Are you asking permission to discuss your idea? If so, you have my blessing.
  7. The statement is a little confusing. I believe its intent was to consider only those values of X which have a probability greater than zero. Simple example: X has 3 values 0,1,-1. f(-1)=1/4, f(0)=1/2, and f(1)= 1/4. g(-1)=0, g(0)=1, g(1)=2. Then E(g(X))=1.
  8. ARPA contribution was setting up the network. I presume, based on your reference, that ASCII was the code used in transmission. At that time IBM had a competing code called EBCDIC. I don't know the subsequent history.
  9. My recollection is that the beginnings of the internet idea was developed by ARPA (now DARPA) around 1960 or so. Their version involved connecting various science research computer facilities and included remote access by outsiders.
  10. Formula (trouble with LaTex) B(x,y)=G(x)G(y)/G(x+y), G=gamma, B=Beta
  11. As long as there is Oxygen around it will catch fire, once it is hot enough. On a hot sunny day, you could start a fire with paper and a magnifying glass.
  12. I'm not absolutely sure, but I believe the time distribution for decay is exponential.
  13. In a world consisting of anti-matter, moving positrons would be electricity.
