Celebrating a true pioneer of computerized geography: Kenneth Appel
I recently read an interesting obituary in The Economist about Kenneth Appel. Perhaps I should've known about him, but I admit that I was unfamiliar with his name. But his famous accomplishment was a major one in the world of geotechnology — a true pioneer. The story starts in 1852 when math-student Francis Guthrie wondered how many colors it would take to ensure that, no matter how complex a map, no adjacent countries would be the same color.
