ASTR 20 Lecture Notes - Lecture 6: Pendulum Clock, Tychonic System, Stellar Parallax
Document Summary
Observed swinging lamps in cathedral of pisa and found period to be independent of the amplitude. Found that projectiles follow a parabolic path. Galileo is credited with the first use of the telescope for viewing objects in the heavens but letters between him and his friends show that galileo wanted to make money selling the telescope for military purposes. Observed the milky way composed of tiny stars and sunspots. The sun is located at the center of the universe and that the earth and planets orbit. In 1633catholic church forbids anyone to read it. Used to demonstrate the law of inertia and that heavy and light bodies fall at the same rate. Galileo also discovered the mathematical laws governing the length of the string, the period of the motion, and the amplitude of the swing. Galileo used the inclined plane to slow the motion of falling objects enough to accurately measure how their speed increased.
