comment How could Eratosthenes measure the circumference of the Earth?
@IQAndreas Deviations probably did skew the result somewhat, and according to Wikipedia's account, between that and natural limitations of "a step is about a meter" he was off by about 7000 kilometers -- about 15%, in other words. Still impressive, given the imprecise tools he had to work with.

comment How did the Nazis plan to defeat America during World War II?
On that note, hasn't North Korea declared war on the US once or twice recently?
