Why you should be upset Boston Public Schools has adopted a new map

The Mercator, a classic map you are probably familiar with
Notice how the loxodrome (rhumb line) crosses every meridian at the same angle. It’s a longer route but easier to navigate. The Mercator was designed around simplifying loxodrome calculations.
The Eckert IV projection from 1906. This has correct areas and close to correct shapes
The Gall-Peters projection. Areas are correct, everything else is wrong.
The Hobo-Dyer map has correct size and most things are close to the correct shape, except Europe
The “Natural Earth” projection, a relatively modern projection that is a compromise map. It doesn’t do anything perfectly, but it does a lot of stuff well, making it a solid choice for a general-purpose map.
