Document Summary
The scientific revolution: 1543-1687, search for science that is experimentally grounded, science of nature, no longer based on ancient traditions, mathematically formulated, search for scientifically proven laws, bases for all thought.

Interest began with solar eclipse: august 21, 1560. Invented angles between planets: wanted to learn how to predict these events, quadrant, found yearly cycle, based on chinese navigation instruments. Isaac newton: 1643-1727, principles of modern physics, laws of gravitation. In motion stays in motion, rest stays at rest, unless outside force: f=ma change in proportional to force applied, opposite and equal reaction for every action, reflecting telescope.
