I am reading a book on Central Asia, in the period of 1000 to 1200. If you had asked me where Central Asia was, my answer would have been incorrect. It is composed of the "stans". You know all those countries that most of us can not find on a map. Kazakhstan, Turkmenistan, etc - the seven "stan" countries. [Stan is a place of - place of Kazaks]
The Silk Road runs through them. Trade was not only with China, but India. The largest city in the world in 1150 was Merv - population 200,000. I know, Merv was on the tip of your tongue.
Astronomy, trigonometry, physics, geography, medicine and more originated in Central Asia.
