Eye Glasses (Spectacles)
Glasses had a BIG impact on history. They allowed scholars to work later into their life. This boosted books production. There was no more fear of getting old. As time went on, until Teddy Roosevelt’s life, glasses were not common among the lower class. When Teddy Roosevelt had his picture taken with glasses on it was considered cool to wear glasses.
Mechanical Clocks
Mechanical Clocks were a big advance in timekeeping. They made it so people could have events at a certain time. The gears inside made two hands move to show time.
Paper Mills
People used to wear linen clothes. When these clothes got old, people wouldn’t use them any more; therefore, someone would come and pick up the clothes, and take them to the mill. There, they would use the mill to smash them into a pulp, squeeze the fibers out, and use the fibers to make paper.
Inventions used in the paper mill: Cam; Gear; Windmill.
