“The map is not the territory”*…

Across the board, the Mercator projection of the Earth—which has been our baseline for world maps since the 16th century—skews the actual size of countries so they look bigger (and therefore, more important than they are) when they fall within the middle of the Northern Hemisphere. It’s not just bad design, it has real geopolitical implications. For example, in most people’s minds, Greenland is a much larger country than Australia. But the reality is that Australia dwarfs Greenland. Likewise, you probably think Africa and North America are roughly the same size, but Africa can swallow all of North America and Greenland with room for all of Western Europe to spare. And so on…  [To redress misperception] James Talmage and Damon Maneice created The True Size. The web app lets you drag-and-drop different countries on a world map and see how they shrink or grow on a standard Mercator Projection map. It’s a simple tool, but an eye-opening one that can be quickly used to show just how skewed our maps really are…

As we ponder perspective, we might might spare a thought for Eratosthenes of Cyrene; he may have died on this date in 194 or 195 BC.  (His exact birth and death dates are lost, so this is as good a day as any to celebrate him.)  A mathematician, geographer, poet, astronomer, music theorist, and Chief Librarian at Alexandria, Eratosthenes is probably best remembered as the first person to calculate the circumference of the Earth (which he did remarkably accurately), to calculate the tilt of the Earth’s axis, and to calculate the distance from the Earth to the Sun (which, again, he did very accurately); and he created the Leap Day.

In his three-volume work Geography (Geographika), Eratosthenes described and mapped his entire known world, dividing the Earth into five climate zones: two freezing zones around the pole, two temperate zones, and a zone encompassing the equator and the tropics.  He placed grids of overlapping lines over the surface of the Earth, using parallels and meridians to link together every place in the world– in the process, coining terminology still in use… He had invented the discipline of Geography.
