 * With the Greeks and Indians developed the logical proof which is knowing some basic thing and then logically moving up what you come up with is true(http://www.historyforkids.org/learn/westasia/science/math.htm)
 * engineering was there true genius and there are many examples of this

 * vertical shafts were dug down from the surface and then a horizontal shaft for a short distance underground that would go to the surface because of the slanted land (engineering and empire, movie)
 * this was very hard not only because the just using rocks to dig this out but the calculations had to be just right for it to work (engineering and empire, movie)
 * Passargade was the first capital of Persia and was a tribute to the Cyrus and the world he was creating (engineering and empire, movie)
 * its centerpiece was two incredibly palaces surrounded by a beautiful park and vast gardens (engineering and empire, movie)
