Oh really? I think there’s at least one error in the calculation

sqrt(2 / (((((pi * 18 000) / (mi^2)) * 80) / year) * (30 minutes))) = 141.683342 meters

What do you think?

    I get a smaller radius (139.33m) since I used the population density of 18,600 from the article.  I recommend changing the equation to have ’2Q’ in the numerator, where Q = quality.  The radius would be directly proportional to the quality, which not only makes logical sense, but it makes the equation more interesting.
