Transcript of The Ancient Greek Legacies

By Hanna Duncan :T The Ancient Greek Legacies The astrolabe was a sort of ancient computer used to help sailors navigate. They were usually about 6 inches in diameter though they could be larger or smaller. They were used for navigational purposes and they could find the time during day or night. Astrolabe They are similar to the modern day GPS. An astrolabe. The Greek architecture was very beautiful; they created intense pillars to support their temples.
The Doric pillar was simplest, it had no base and got thinner towards the top. The Ionic was more complex due to its skinnier shape and its spiral pattern. The Corinthian was the most complex, it had leaf engravings near the top.
In modern day the Greek pillars are used in temples, government buildings, and monuments. Architecture Ore smelting is used by melting a precious metal out of the ore it came in. It was used in gold, iron, and bronze. It could remove the impure parts of an ore so the remains could be used in armor, weapons, and other objects.
Casting is heating the smelted ore to the point where it melts, to put into a mold where it could harden into a specifically intended shape. This was used in armor and weaponry. Today it is used in machinery to create the metals needed to create the machine parts.
Ore Smelting and Casting What ore smelting today looks like. The pulley block system was a simple machine consisting of of a wheel with a groove in which a rope or chain was put, then an object was attached to the other end of the chain and it would lift. It was used to lift heavy objects humans couldn't lift, and it was created by a mathematician named Archimedes.
It is now used in modern day machines such as a crane. The crane uses the pulley block to hook onto things and pull them upward.

The same general idea was used in "Snow-Motors" to throw snow particles out of the way for cars to move easily through the road.
