Sebastian, do you know the specific name of the statistical principle you're invoking? I agree, but [[User:St.nerol|St.nerol]] does not, and he has a quick tendency to remove things. One part of it is that you don't know the magnitude of a number, exponential distribution is a more appropriate model than linear. Another part is about the unlikelihood of the middle digits being zero. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 21:37, 11 January 2013 (UTC)

I understand how the hidden numbers could mean that a volcano could either erupt very soon or a very long time.  But I don't get why this is a joke.  Is there something funnny that I am missing?

Zeroes

If you assume (with nothing else known), that large numbers have a probability about reciprocal to themselves to ensure a sum/integral of 1, the digits not being zeroes is extremely unlikely.

Whether black hat guy thinks a supervolcanoe eruption is a favourable event or being spared from one is not made entirely clear. Sebastian --178.26.121.97 08:56, 11 January 2013 (UTC)

I warmly recommend the article harmonic series (mathematics). ;-) --131.152.41.173 13:30, 11 January 2013 (UTC)
You are right, the harmonic series is divergent. However, the maximal number of digits - which can be possibly displayed - is finite. Which distribution would you suggest? Sebastian --178.26.121.97 19:35, 11 January 2013 (UTC)

Sebastian, do you know the specific name of the statistical principle you're invoking? I agree, but St.nerol does not, and he has a quick tendency to remove things. One part of it is that you don't know the magnitude of a number, exponential distribution is a more appropriate model than linear. Another part is about the unlikelihood of the middle digits being zero. - Frankie (talk) 21:37, 11 January 2013 (UTC)

Volcanoes

"I forget which one" may be a reference to the 7 known supervolcanoes, or it might be to a list published by the Guardian in 2005 of the top 10 existential threats to life on Earth, which went briefly viral. It included a supervolcano eruption, as well as viral pandemic, meteorite strike, greenhouse gases, superintelligent robots, nuclear war, cosmic rays, terrorism, black holes, and telomere erosion [1]

I understand how the hidden numbers could mean that a volcano could either erupt very soon or a very long time. But I don't get why this is a joke. Is there something funnny that I am missing?
