Re: doomsday argument

Hi. Well, to be honest, I checked the words on babelfish.altavista.com translator. It said something like "law of a hyperbolic increase in the population of the Earth". Well, the doomsday argument article itself says something about the population increasing so rapidly that it reaches infinity at some given date, therefore sparking doomsday, which can roughly translate to as a hyperbolic increase in global population. The English Wikipedia article had a graph showing the population of the world from 10,000 years ago to present, showing a large spike in population in the present. Well, the Russian interwiki link had that same image. The doomsday argument article apparently talks about a mathematically-calculated increase in population towards infinity. I don't understand the Russian article, but with the same graph, and the title translating to as a hyperbolic increase in population, which is what the English article pretty much talked about, I decided to re-add the link. Also, why would the Russian Wikipedia link be "Doomsday argument", which is in English, as the IP had posted, when the Russian interwiki link translated roughly to the same meaning as the English article, even if the Russian title did not have the words "doomsday" and "argument" in it? Also, apologies for not being able to explain my revert in the edit summary, the "undo" summary was taking up most of the space in the edit summary. Why is the Russian link not correct? Thanks. ~AH1^(TCU) 17:37, 11 April 2008 (UTC)

The problem here is that DA is not about exponential growth. you can see it in the beggining of the article: "The Doomsday argument (DA) is a probabilistic argument that claims to predict the future lifetime of the human race given only an estimate of the total number of humans born so far." So ONLY the estimate of humans born so far. Exponential grows is another teory. We can say that Foerester theory about exponential grows is a kind of DA, but not vica versa. DA - is general term, and foerester expotential grows - is possible part of it; I am translating now the full enTurchin (talk) 19:20, 11 April 2008 (UTC)glish artcile about DA on Russian.
