The Maya had a better solar year determination
(tracking of the winter solstice) than
the Europeans did in 1582AD before 900AD, how did they do this?
This planetarium program will be about the mathematical accomplishments
(zero has only been invented twice by humans) and the extremely
sophisticated astronomical observations
and calenderical calculations of the Mayans. Images of the
abandoned city of Tikal, Peten, Guatemala and some stone stela from
Tikal and else where will be shown.
Mayan, base 20, Vigesimal Numbering System, for numbers not day
Same number for day dates, mostly base 20, but one register, the
third from the lowest, is base 18.
