Maya Technology
Maya Technology The technological advances of Maya engineers have been investigated by Jim O'Kon for forty years. His research has included a wide variety of technical developments of the Maya. We invite you to visit this website to review the unique technological/engineering achievements of the Maya engineers. These technological achievements include the fabrication of tools that are harder than iron; the invention of high strength durable materials of construction including the fabrication of hydraulic cement for producing cast-in-place concrete; the development of the Maya arch as a structural mechanism to create multi-story and clear span structures, elevated concrete paved roads; long-span bridges, and advanced water management methodologies that permitted the Maya urban civilization to survive in a seasonal desert environment. Archaeologists consider the Maya to be a Stone Age Culture. Transport Read more: Transport Jadeite is a very hard and durable material. Short span bridges

Kaminaljuyu
An excavated portion of the Acropolis Kaminaljuyu and other Preclassic sites Kaminaljuyu (pronounced kaminalχuʲu) is a Pre-Columbian site of the Maya civilization that was primarily occupied from 1500 BC to AD 1200. Kaminaljuyu has been described as one of the greatest of all archaeological sites in the New World by Michael Coe,[1] although its remains today – a few mounds only – are far less impressive than other Maya sites more frequented by tourists. When first mapped scientifically (by E. The known parts of Kaminaljuyu lie on a broad plain beneath roughly the western third of modern Guatemala City. The Kaminaljuyu site largely was swallowed up by real estate developments in the late 20th century, although a portion of the Classic period center of Kaminaljuyu is preserved as a park. The state of destruction and the almost daily erasure of archaeological context underscore the many mysteries, in addition to size and scale, that likely will remain unanswered about Kaminaljuyu.
Eclectic Librarian
“Cats that Webchick is herding” by Kathleen Murtagh Presenter: Sheri Ross, St. Catherine University She teaches a course on ERM, which is why she’s doing this research. She interviewed ER librarians about their work, their institution’s workflow, and their perspectives on the competencies. Most had paraprofessional experience with web design, reference, serials, ILL, and archives. Their typical day “depends on the time of year,” which affirms the importance of understanding the lifecycle of ERM. Though they had many different roles, there were some commonalities: troubleshooting access and other issues, primary point person for vendor communication, and working closely with subject specialist and systems/IT personnel. The interview took the Core Competencies and lumped them into four broad areas and didn’t specify the source: technical, analytical, legal, and interpersonal. Second most important was analytical. First most important were interpersonal competencies. Is 16 a good sample?
Preclassic Maya
The Preclassic Period in Maya history stretches from the first Maya settlements until 250 AD. The major cites of this period were Kaminaljuyu and El Mirador. By the end of the Preclassic, the city state of El Mirador had united the southern Maya lowlands.[citation needed] However, from 100 to 300, this empire began to decline, and the city was eventually abandoned. It is likely, but by no means certain, that the rulers of El Mirador became the Kan dynasty of Calakmul,[1] where they would regrow to become one of the two dominant powers of the Classic Maya period, along with their rival Tikal. History[edit] Early Preclassic (2000 BC–1000 BC)[edit] Middle Preclassic (1000 BC–400 BC)[edit] By around the year 1000BC, centuries of agricultural village life had begun to form the beginnings of a complex society: Prestige goods such as obsidian mirrors and jade mosaics began to appear, increasing the demand for more extensive trade. Late Preclassic (400 BC–100 AD)[edit] Preclassic "Collapse"[edit]
