Geocentric Theory During the Middle Ages most scholars believed the earth was unmoving, and was the center of the universe According to the belief, the sun, moon and other planets revolved around the earth This was known as the Geocentric theory Was supported by Aristotle and Greek astronomer Ptolemy The church supported this theory as well, and taught that God had purposely put the earth in the center of the universe

This is the Ptolemaic view of the solar system

Nicolaus Copernicus Studied planetary movements for over 25 years Created the Heliocentric Theory First to say the Sun is at the center of the universe, not the earth. Later supported by Galileo and Kepler

Johannes Kepler After Copernicus published his theories, other scientists tried to prove them Kepler proved Copernicus’s theories were true by using math

Galileo Galilei Scientist, and Inventor Created the first telescope in Italy discovered the law of acceleration Published “Dialogue Concerning the Two Chief World Systems” that presented both Geocentric and Heliocentric views – but sided with the Heliocentric Theory http://www.youtube.com/watch?v=fHh3jJoW3zA

Galileo lived under house arrest and died in 1642 at his villa near Florence His books and ideas still spread all over Europe In 1992, pope John Paul II officially acknowledged that Galileo was correct in asserting that the earth revolves around the sun, but concluded that the church acted in good faith, and worked with the knowledge of their time Seriously??

Sir Francis Bacon Created “The Scientific Method” The scientific method is a logical procedure for gathering and testing idea 1. Come up with question 2. form a hypothesis 3. experiment 4. analyze and interpret data 5. conclusion

Isaac Newton Discovered the Law of Gravity Newton’s great discovery was that the same force ruled the motions of the pendulum, planets and all matter on earth and space In 1687, Newton published his ideas in a work called Mathematical Principles of Natural Philosophy In the book he described the universe as a giant clock, with all parts working together perfectly explained mathematically

Edward Jenner - Vaccines introduced a vaccine to prevent smallpox He did this by using live germs from cowpox (cattle disease, but much milder than smallpox) Inoculation had been used in Asia for years, and could be considered dangerous, but because he used a milder disease, the risks were lower **inoculation- to put a small dose of a disease into the body of a person in order cause immunity **
