Back to America: A.D. 501 to 600

By 600 A.D. the cultural primacy in North America had passed from the Hopewell area to the lower Mississippi valley, particularly in the fertile flood plain between St. Louis and New Orleans, the land of the Mound Builders. (Ref. 215 ).

In the southwest the Anasazi Indians continued to multiply, with Basket-maker sites extending from the region of present day Lake Mead in Nevada, through southern Utah into the southwest corner of Colorado and then down to northwestern New Mexico and northeastern Arizona. By both archeomagnetism dating of charred wood beams of burned pit-house ceilings and tree-ring dating, their society can be followed in this large area quite exactly. (Ref. 277 ) The Hohokam Colonial Period and the Mogollon Cultures continued south of the Anasazi.

About A.D. 600 a distinctive group of Indians appeared near the lower end of the Colorado River (southwestern Arizona and an extreme eastern slice of California). These were called the Patayan (also Hakataya) and were Yuman-speaking people who used the flood plains of the Colorado delta for farming, had a unique paddle and anvil pottery decorated with red paint and ground their corn on a trough-shaped metate. Living in this area for 900 years, they became then the modern Yumas, Cocopah, Maricopa, Havasupai, Mojave and Walapai. (Ref. 45 , 210 ) Consistent with his other claims, Fell (Ref. 66 ) purports to read Islamic inscriptions on certain Nevada rocks and feels that Arabic Libyans made these shortly after A.D. 650 when Islam came into North Africa.

Mexico, central america, and the caribbean

By A.D. 600 Teotihuacán in Mexico had a population of perhaps 150,000 to 200,000 and covered about 8 square miles. The city was laid out in a precise grid pattern with large city buildings and apartments for families, offering a maximum of privacy in a crowded city. There still is considerable confusion as to the people who lived in this community.

As mentioned in a previous chapter, old Indian legend called these people "Toltecs" and this may be accurate, even though current usage reserves this term for the later rejuvenated civilization centered at Tula in the 9th and 10th centuries. By at least 650, Teotihuacán was beginning to show signs of impending collapse and the reason for this is another thing that has not been clarified. (Ref. 45 , 215 , 176 )

The lowland Maya made a strong comeback in this century, with several centers flourishing. At least 45,000 people lived at or around Tikal and its sprawling pyramids, temples and house mounds covered some 38 square miles in the dense rain forest of northern Peten.

The most elaborate structure was the so-called northern Acropolis, which covered 2112 acres with 100 buildings and at one time 16 temples. At the same time the Yucatan Mayas were also active. (Ref. 45 , 215 ) The Period V Culture continued in Costa Rica, as noted in the last chapter.

South america

In Peru the balance of power after A.D. 600 shifted from the coast to the highlands where the city of Tiahuanaco and the Huari military machine dominated the central Andes by carving out empires that included not only all of Peru and Bolivia, but also part of northern Chile. There were still coastal people of the Nazca Culture, however, and a study of the skeleton of an 8 year old boy from around A.D. 700 in this area showed classical Pott's disease (tuberculosis of the spine) with a psoas abscess, renal disease, pericarditis and terminal miliary tuberculosis of his lungs. In the north there was still Moche influence, perhaps manifested at that time in the Chimu Society, although dating has been difficult. (Ref. 8 , 3 )

what is fullerene does it is used to make bukky balls
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.

is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
