The Orbital Rings symbolized the first man-made satellites.
-
Was built on the same "foundation" that supported the
Perisphere.
-
Enormous stresses would be put on the structure because the
Continents are not evenly distributed. High-speed computers were needed to
process the large numbers of mathematical equations necessary for construction.
One problem alone required the use of 670 equations processed simultaneously.
-
US Steel funded the construction in exchange for the publicity.
-
The Unisphere had the dimensions of the Earth as viewed from
6000 miles in space.
-
Capitals of prominent nations were illuminated with lights.
-
One additional light was placed at the Caughnawage Indian
Reservation (off the St Lawrence River between the US and Canada). This was to
honor the 50 Mohawk Indians who built the Unisphere. And without a single injury.
-
Was the World's Largest fabricated structure made with
Stainless Steel.
