Big Data

  As a preparation for the class we were supposd to either watch some videos or read one of the suggested articles. All of those were concerning the so-called Big Data. One of the videos was a talk give by Hans Rosling. Now he was focusing on human health and he'd take for exampl child mortality or life lenght and show the averages of different countries over the years starting from 1970s. The main thing you'd see is that the developing or poorer countries (in Asia, Africa or Latin America) are now very quicky trying to 'catch up' with the developed cointries. But they all have different paths in which they're doing that - the quickest ones improve first on their health - they live longer and less of their children die (they also have less of them now). Once their health condition is better, their earnings or GDP inceased cinsiderably quicker than the other countries.
