Greetings, all. I have a few questions re how people with Practical Planetology have dealt with things in the book. First, how do the maps they provide work? They say they are using something called an "Eckert Equal Area Projection". I just don't know how the damn thing is supposed to fold to turn into a globe. For one thing, the description of Falx says Tentacles-Grip-Tightly and Brain-in-the-Skull are at opposite poles. On the map, one city is at the top, and one is at the middle line. The second problem is with the map of Radole. It places the gate to the Negative Energy Plane on the middle line, halfway betweent the edge of the map and the shield mountains that divide the dark and the light sides. But the gate is supposed to be at the coldest part of the planet, presumably the part furthest away from the sun. So, I have two mental pictures of how to "fold" the maps so that they become a globe. The first is to roll the map longwise into a cylinder, so the bottom edge touches the top, then fold the ends of the cylinder into hemispheres, creating a globe. This agress with Falx, because the horizontal center line becomes one pole, and the top and bottom edges of the map become the other pole. However, it does not agree with Radole, because then the Negative Energy gate is about halfway between the shild mountains and the point on the planet furthest from the sun. The second way of folding I thought of is to make a cylinder by touching the shorter, curved edges to each other, and streching the top and bottom edge until it forms a single point. This puts the Negative Energy gate at the coldest point on Radole, but it has problems too. First, the habitable band on Radole then only goes around half the planet, from pole to pole, and on the other side the sunside and darkside meet with nothing in between. The second problem is that it puts the cities on Falx at the wrong places, one at the north pole, and the other on the equator. If anyone knows where I might find a description of an Eckert Equal Area Projection, or has a better idea of how to visualize the maps as globes, please let me know. Thnx :-) === Isn't preventing STDs by abstinence a lot like preventing food poisoning by not eating?
