10. Isaac Newton English mathematician, astronomer, and physicist
Principles of Natural Philosophy or Principia 1642
Invented calculus
Discovered laws of light and color
Formulated the laws of motion
Objects are in a state of rest or motion in a straight line;
Rate of change is proportional to the forces acting on it;
For every action is a opposite and equal reaction;
Law of gravitation, which explains why the heavens are in motion
World as a machine view of natural laws!

Philosophy: Enlightenment and ideas on government
Religion: the Church, rather than embracing the ideas created a conflict between faith and science;
World: challenged traditional beliefs about the organization of society, application of science to solve problems in society
