Can a new map fix our distorted views of the world?

Starting in 2006, J. Richard Gott, an astrophysicist at Princeton, and David Goldberg, a cosmologist at Drexel University in Philadelphia, developed a scoring system that could sum up the difference in map projections and their shortcomings. Since then, Dr. Gott created a new kind of double-sided map, crafted with Dr. Goldberg and Robert Vanderbei, a mathematician at Princeton, that aims to minimize six types of map distortions.

They made the world map a double-sided circle, like a vinyl record. You could put the Northern Hemisphere on the top side, and the Southern Hemisphere on the bottom, or vice versa. Or to put it differently: You could deflate the 3-D Earth into two dimensions.

Cartographers who regularly study world maps — perhaps fewer than 10 people in the world — will now have time to react. “It never came up to me that it could be done in this way,” said Krisztián Kerkovits, a Hungarian cartographer working to develop his own projections.

But while the new map excels at addressing distortion, Dr. Kerkovits said it also introduced a new weakness: You can see only half of the planet at once. That undermines the basic premise of flaying out the whole world for inspection on a single page or screen.
