After university I spent a summer exploring Mayan pyramid sites in Central America - another
much under
researched civilisation who developed one of the most accurate calendars and
astronomical charts until the modern computer age and built palaces and pyramids on a par with the European classical period.
Although the United States has been a world leader in
astronomical research during
much of the 20th century, other countries have advanced rapidly, so that in some cases their facilities are competitive with — and for some purposes, even superior to — U.S. facilities in optical ground - based astronomy.1 The United States can benefit from international collaboration, but only if it brings world - class capabilities to the collaboration.
