... The retweet numbers are close to the values that Twitter has for the tweets, which means that I can't have messed up too much (I wouldn't expect perfect agreement since Twitter does not guarantee that any search will return all matching tweets; also, the Twitter values are updated whereas mine are fixed until the next set of tweets gets analyzed). The most re-tweeted accounts. ... Below I show the distribution of the number of times an account tweeted (this excludes retweets made by the account). ...

... What's a Population . ... It varies, ecologists use the word "population" in several ways; typically a "somewhat isolated collection of individuals." ... There are two "basic models" of population growth. Exponential growth, and logistic growth. ... In logistic growth there are "density-dependent" changes in growth rate that REGULATE population growth. ... The exponential and logistic models treat all individuals in a population the same; but we know that baby's don't reproduce but adults do! ...

... Screening the data on the Flare column requires the user to keep several things in mind when interpreting the data down to 200 eV. Spectra: They are problematic as all photons in the given PHA range during soft flares are removed from the eventfile (both source and softflare events). Spectral fits to the screened data can be performed for PHA values greater than the upper PHA limit given by the user. ... But below the upper PHA limit the same applies here as for the spectra. ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

... Bad Astronomy . ... Mad Science . ... If the universe was considered a singularity at the moment just before the big bang, why would there be the question of how information was relayed to account for the uniform temperature? I assume you mean that since, at the moment of the Big Bang, every point in the Universe was in contact with every other point, so information was relayed instantly. ... It's possible that, even though the Universe was still ``small'', it had fluctuations in it. ...
