Hello?

OpenStudy (tkhunny):

Forget that "A" business. Look up "Mercator Projection" and "Robinson Projection" and "Winkel Tripel Projection" The Mercator Projection fills in the gaps and creates massive distortions near the poles. The Robinson Projection cuts up the map near the poles, trying to retain proportions. The Winkel Tripel tries to make a spherical shape of the whole idea. National Geographic changed from Robinson to Winkel Tripel in 1998. If I recall correctly, sometime earlier, they switched from Mercator to Robinson and made Canada angry, since Canada now appeared to be 20% smaller.

So A

OpenStudy (tkhunny):

Correction, National Geographic changed from Van der Grinten to Robinson in 1988.

What does "Forget that "A" business" mean to you? Think about C.
