Mayan history and architecture on natgeo
On August , 2007 an special issue of National geographic magazine got published with marvelous description and snapshots of the Mayan ruins.
We can have an idea about how advanced they were ... "Though they used neither the wheel nor metal tools, they developed a complete hieroglyphic writing system and grasped the concept of zero, adopting it for everyday calculations. They also had a 365-day year and were sophisticated enough to make leap-year-like corrections. They regularly observed the stars, predicted solar eclipses, and angled their ceremonial buildings so that they faced sunrise or sunset at particular times of year."
And isn't it sarcastic joke to celebrate the "discovery" of America when there already was a civilization with years of cultural background !
