Back to Central and Northern Asia: A.D. 801 to 900

Just northwest of the western end of the Great Wall of China, the Tanguts (a Tibetan tribe) founded the powerful kingdom of Hsi-hsia in the areas of Ninghsia and Kansu. The Khitan Mongols, under their dynastic founder, Ye-lu A-pao-Chi (907-926) conquered all Inner Mongolia and, as we shall see later in the chapter, most of Manchuria and northern China. (Ref. 119 , 279 ) To the southwest the Khwarism (Khorezm) Turks took their name from their ancient and medieval state centered on the basin of the lower Amu Darya River and in 995 the country was united under the emirs of north Khwarism whose capital, Urgench, became a major seat of Arabic learning. (Ref. 38 , 8 , 125 )

Afghanistan fell to the Turks of Turkistan in A.D. 962. The Samanid Emirate, extending east from Persia, was partially crushed and Transoxiana lost to the Karakhanid Turks in 990 but it remained for another Turk, General Mahmud, one of the greatest figures in Central Asian history, to completely overthrow the Samanids in 999, initiating the Ghaznawid Emirate in that entire area of southern, central Asia. Bokhara and Samarkand continued to be great centers of learning and art while the great Friday Mosque at Herat was already attracting scholars and philosophers from all over the Islamic world. (Ref. 137 , 144 )

In Tibet the two wives of one of the kings converted him to Buddhism and after that Chinese writings were brought into the nation. One such writing, the "Tanjur" contained medical information. (Ref. 125 )

Forward to Central and Northern Asia: A.D. 1001 to 1100

Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
