Of course, "torrid" is in blue, while "temperate" is in red, which is the opposite of the standard idiom of hot=red, cold=blue. Of course, those of us that have deep understanding of physics (especially astrophysicists) would say that hot=blue, cold=red.Baluncore said:
But their tropical sphere is painted red, so they reversed the convention when printing the torrid sign.swampwiz said:
An armillary sphere is a model of the celestial sphere, used to represent the movements of the stars and planets in the sky. It consists of a network of rings representing the equator, meridians, and other important celestial circles.
An armillary sphere works by using a series of rings and circles to represent the celestial coordinates of the stars and planets. By rotating the rings and adjusting the position of the armillary sphere, one can track the movements of the stars and planets in the sky.
The main purpose of an armillary sphere is to serve as a teaching tool for understanding the movements of the stars and planets in the sky. It can also be used for navigation and as a decorative piece.
The armillary sphere in Australia is likely a replica or a decorative piece. Armillary spheres have been used for centuries and can be found in many different countries as both functional and decorative objects.
The armillary sphere was invented by the ancient Greeks, but was further developed by the ancient Chinese and Arabs. It has been used by many civilizations throughout history and continues to be used today.
