it was either made in the date of 255 BC or 150 A.DI'm not sure (read it in books!)
An armillary sphere is a device for studying the rotation of the earth and other astronomical bodies (i think lol)
no, a sphere is a ball.
no. bubbles can only be made into sphere shapes.only a trick can make a bubble into a different shape
A hemisphere is a half of a sphere, divided by a plane passing through its center. It has a flat base where the cut was made, while a sphere is a three-dimensional shape with no flat surfaces. The hemisphere has a curved surface area and volume that are half that of a full sphere.
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.

An armillary sphere is an instrument consisting of graduated metal circles used to represent the motions of celestial bodies around the earth.
An armillary sphere is a model of the celestial sphere. It consists of a set of rings representing different celestial circles, such as the equator and the ecliptic. By rotating these rings to align with the position of celestial objects, users can track the motion of the stars, sun, and planets in the sky.
Ancient people saw Saturn, including Claudius Ptolemy, who used an armillary sphere - a device made of metal rings - to track all of the stars and planets.

Chinese inventor Zhang Heng is credited with several inventions. The world's first seismometer is one of his inventions. Zhang Heng also invented the water-powered armillary sphere.

This is a sphere made from a metal.

Ptolemy made his astronomical observations primarily using instruments like the astrolabe and armillary sphere. He observed the positions of stars and planets in the night sky and used his observations to develop his geocentric model of the Universe.
Su Song's water clock tower is the biggest because it was 30 feet tall!!!!!!possessed a bronze power-driven armillary sphere for observations, an automatically rotating celstial globe, and five front panels with doors that permitted the viewing of changing mankiins which rang bells or gongs.
