Beginning of modern science Scientific method: Depends upon logic, observation, and reason rather than faith Created the technologies and techniques that built the modern world Created paradigm of our solar system Paradigm- model

Epistemology- study of knowledge Universities formed Rediscovery of classical science Leading figures – Bacon – Brahe – Copernicus – Descartes – Galileo – Kepler – Newton

 Earth revolves around the sun  Book On the Revolutions of the Heavenly Spheres  Heliocentric theory:  Sun is the center of the universe

 Danish royal astrologer  Astrologer- Studies the stars  Follower of Ptolemaic system  Ptolemaic system- Geocentrism (earth is the center of the universe)  Observed and mapped over 700 stars in a 20-year period

 Preferred inductive reasoning and facts over theory  Inductive Reasoning- process where a small observation is used to assume a larger theory, without necessarily proving it  Ex.-Jennifer leaves for school at 7:00 a.m. and is on time. Jennifer assumes, then, that she will always be on time if she leaves at 7:00 a.m.  Invented the scientific method

“I recant” Invented the telescope, pendulum clock, thermometer, water pump, and sector Discovered speed of acceleration for gravity Sentenced to house arrest by the Catholic Church due to his belief of heliocentrism and belief that you could still believe something even if the Church said it was false

Brahe’s student for 20 years Lived during 30 Years of War Loved the planets and made it his life’s work to explain the motion of planets Invented Three Laws of Planetary Motion

 Deductive logic  Using what you know is true to prove that something else is true  Ex. Since all humans are mortal, and I am a human, then I am mortal.  Deduced the existence of God  Invented Cartesian geometry ( xy axis)  Famous Quote- “I think therefore I am”

Wrote The Principia which published his discoveries in science Tied up the loose ends of Kepler and Galileo Three Laws of Motion Defined gravity and its laws every object in the universe attracts other objects Gravity is responsible for the movement of planets, moons, etc. Invented optics and calculus

 Developed the modern scientific method  Universe ordered according to natural laws  Discovered that scientific laws can be discovered by human reason  Took the role of a deity or god out of the study of the universe  Deistic view of God
