The impressive expansion of subway systems in China

I have posted in the past a GIF that compares the expansion of the subway systems of Rio and Shanghai between 1979 and 2014. This is a bit embarrassing for Rio, for sure, but let's be honest. Pretty much any developing county and even the USA in their efforts to develop mass transport infrastructure pales in comparison to China. Needless to say that massive expansion of infrastructure like this usually comes at high social and environmental costs that should not be neglected.

Peter Dovak (twitter) has created a new GIF that shows the expansion of subway systems in China between 1990 and 2020, giving a glimpse of the Chinese urban powerhouse. Peter has other great projects you might want to check out, including the Mini Metro Maps of the world.

Changing relation between wealth and left-wing vote: Piketty's guess on the French elections

I don't usually post about politics in the blog, but I had the chance to attend Thomas Piketty's presentation at the Marshall Lectures over the last two days and he dedicated a few minutes of his speech to talk about the 2017 French elections happening this weekend. 

He presented these two slides, where he shows the changing relationship between wealth + education and left-wing vote in France. The slides show what is Piketty's guess on what is going to happen in the French elections.  Hi guess are the red lines in both charts, suggesting that Macron will win the election. I think I'll just leave this here, for the record.

update after the elections: so, apparently, Piketty was correct.
