The four colour theorum hits the internets

Ah, a perfect microcosm of internet life.

Stage 1: 'Science News' publishes on its site an interesting-enough article on the 'four colour' theorum. Opening paragraphs, to remind you of the f.c.t. -

In 1852, botanist Francis Guthrie noticed something peculiar as he was coloring a map of counties in England. Despite the counties’ meandering shapes and varied configurations, four colors were all he needed to shade the map so that any two bordering counties were different colors. Perhaps, he speculated, four colors were enough for any map.

Little did Guthrie know the load of trouble he unleashed with his innocent conjecture. It took mathematicians nearly a century and a quarter to prove him right, and even that wasn’t enough to close the Pandora’s box Guthrie had opened. Mathematicians pulled out their markers and tried to color everything in sight.

Stage 2: An arrogant and intellectually challenged man leaps in to comment -

Imagine a map where every county was a hexagon. Every county would touch 6 other counties, and this map would, at a minimum, require 7 colors so that any two bordering counties were different colors. "It took mathematicians nearly a century and a quarter to prove him right". It took me two seconds to prove the statement in this article wrong.

Stage 3: Bob is politely corrected -

Sorry Bob, but you are the one in error. To need seven colors requires not only that each country touches six others, but that each of those countries touch the same of those other six, which does not occur. You have cliques of three, and you require three colors.

And stage 4: Bob is mocked -

@BobTook me 3 seconds to read your comment, and took me a LONG time to finish laughing. This country needs to catch up in Math&Sciences. No wonder the Asians and the European are laughing at us...
