Eli Whitney patented a mechanical way to process cotton gin in 1794. Whitney's gin pull the cotton through a combination of a wire screen and small wire hooks, while he prevent jams by using brushes that continuously remove the loose cotton lint. Modern gin uses modules to transport cotton and therefore it is needed to use spiked rollers to remove the cotton, then the cotton is held by rapidly rotating saw cylinders.
The Classical Period represented a consolidation of the basic elements of human civilization, thus overcoming our ancient nomadic lifestyle of hunting and gathering. The stablishment of ancient civilizations meant having the means to maintain a sedentary lifestlye, starting with agriculture and cattle raising. Then as cities grew more complex concepts became of everyday use, such as economy or religion.
The Classical Empires, such as Egypt, Mesopotamia, Persia, the Greek city-states, Carthage and Rome, expanded not only military power but economic growth, religion, language, the development of arts, technology and philosophy. These concepts started thousands of years ago, and became widespread because of the prosperity that sedentary lifestyle allowed in these empires, each one making its particular contribution to humanity.
