CHCS Earth Science Chapter 2 (p32-37)

QuestionAnswer
Nicolaus Copernicus Polish astronomer who is credited with proposing the Heliocentric Theory
heliocentric theory AKA Copernican Theory; "Sun centered"; theory placing the Sun at the center of our solar system
Tycho Danish nobleman; most accurate astronomer; believed in the geocentric theory; his observations were used to help prove the heliocentric theory correct
Johannes Kepler German Christian and mathematician; persecuted and left Germany; worked for Tycho; used Tycho's observations to mathematically prove the Heliocentric Theory
Galileo Italian mathematician and scientist; first to use the telescope to view the heavens; provided physical evidence for the heliocentric theory; persecuted by the Catholic church
4 things Galileo saw through his telescope 1) imperfect surface of the sun 2) Saturn had bulges (later seen as rings through a better telescope) 3) Venus has phases like the moon 4) the four largest moons of Jupiter ...called the Galilean moons
What the 4 things Galileo saw through his telescope proved... 1) the universe is not perfect, as was once thought 2) not everything revolves around the earth 3) little things revolve around big things, so it makes more sense for the little Earth to revolve around the big sun
Sir Issac Newton English mathematician and scientist; formulated the law of gravitation
law of universal gravitation large bodies attract smaller bodies; the closer two bodies are together, the greater the attraction between them
