I had to check out a few websites to get those definitions that were thrown about:
http://thesaurus.maths.org/dictionary/map/word/3108 http://mathworld.wolfram.com/IsotropicLine.html http://www.polaris.iastate.edu/NorthStar/Unit1/Talking/Arm/NFSubtend/bod y_nfsubtend.html Now that that is done....<rant>WTF does isotropic have to do with the question? We start with one asteroid 400,000 from earth and somehow we end up with 200,000,000,000 asteroids 40,000,000 miles from earth. Why? (And if 1000 out of 200,000,000,000 pass within 4000 miles of the center of the earth, then wouldn't the final ratio be 200,000,000:1? How can you get one number, act like you needed something ELSE from that work, and then not use it at all?) </rant> But now I understand what was said. From the asteroid's point of view, the earth is a pi*4000^2 circle on the surface of half a 4*pi*400,000^2 sphere. Why couldn't you just say that in the first place? Kevin T. Work? What work?
