Mr. Schlafly, I'm a bit confused about a minor point in this lecture. It says, ''The Qin dynasty began to construct the Great Wall to defend against foreign invaders, which stretches today for 1,400 miles and is the only man-made structure easily seen from outer space.''. I've just been editing the CP article on the [[Great Wall of China‎]] (mostly for grammar, but I did some reference-checking too), and it says that the Wall is ''not'' easily seen from outer space, that it can barely be seen at low orbit, and that other man-made structures are easier to see, which is a bit different than what you've said here. Could you take a look? I know this is a fairly minor issue in the big scheme of things, but we don't want to confuse our students by saying two different things. (Remember, I'm far from an expert in either Geography or China!) Thanks. --[[User:Hsmom|Hsmom]] 13:54, 10 March 2009 (EDT)

:If I recall correctly, Hsmom is right. Several cities (New York, etc) are visible from space, but ''not'' the Great Wall. [[User:EdGlorpus|EdGlorpus]] 20:31, 11 March 2009 (EDT)
