Last Friday’s post looked at visualizations for the relative sizes of celestial objects. But for most of us, a Blue Supergiant Star remains something of an abstract concept. This week, a look closer to home, the actual sizes of countries found an a world map.
We’re all likely familiar with the standard map in use these days, called the Mercator Projection, but did you know that the sizes shown for various countries are wildly inaccurate? It turns out that it’s really hard to accurately adjust when going from a spherical world to a two dimensional map. As such, countries near the poles are shown as much larger than they actually are, and countries near the equator are shown smaller.
The video below does a nice job of showing some of the actual relative sizes of countries. We learn how small the UK is, how large countries like Japan and Brazil are, and how seemingly impossibly enormous Africa is. And then there’s Greenland, which on the map looks like a continent, but in reality is just a large island.
