Renaissance+Science

This picture shows the invention the astrolabe, created during the Renaissance. Back then sailors were exploring for new routes and new lands, but they didn't want to get lost at sea. This way if explorers found new land, they would know how to get back. Also sailors could now go out to sea and find areas rich with fish, and by having the latitude they could return there and fish again. The astrolabe gave explorers a way to check their latitude at sea. Economically this gave people better access to new routes, which could make them money. Political rulers could send out messengers to convert foreigners to their religion and teach them their beliefs. Overall the astrolabe opened new and grand opportunities for explorers and sailors. || Isac Newton was a very modest man. He explained the earth’s gravitational pull and centripetal force were very clear to him, and that he has been studying for 20 years. In 1684, Edmund Halley visited Newton to ask some questions. When he was there, he told himthat his rival, Robert Hooke, was looking for an explanation. Newton never married and was proneto fits of temper when challenged by hisadversaries. He was known to be extremely absent minded, especially when he was pondering a theoretical problem. || The Ptolemaic System, everything revolved around a fixed center. Beyond the earth was the Moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn and then the stars. Beyond the stars was the Prime Mover or the first cause, god. This picture shows a blue circular disc that helped show where all the planets would be at that time of month or year. Through the dedication and work of a few curious minds, a new world view began to emerge. Popular belief held that human beings sat on top of the world which was at the center of the universe. ||
