This is the 500th post I have published on the Spanish version of this blog, just after 11 years since the creation of, on January 15, 2014. The English blog, PopulScience, where I almost always publish the same posts, translated into English, came about later. I did not publish the first article until August 12, 2014, so it was half a year late. However, over the years, it has gradually recovered the lost ground, to the point that right now there are 498 posts, only two less than the Spanish blog.
Why is this? It is very simple: in the United States the summer holidays are shorter and end in mid-August, while in Spain the whole month of August is a non-working month. When I take a vacation from the blog, I stop publishing posts in the Spanish version for most of July and all of August, and start the new course at the beginning of September. On the English blog, however, I start in mid-August, and so every year I catch up on two or three posts. After eleven years, I have almost made up for the half-year delay that the English blog was behind. This summer, God willing, the two blogs will be on a par.
