MAJOR FACTORS LEADING TO THE SCIENTIFIC REVOLUTIONMAJOR FACTORS LEADING TO THE SCIENTIFIC REVOLUTION

-rise of universities in the High Middle Ages -broadening of the curriculum

-rising community of intellectuals pursuing knowledge

interest in the idea of human potential and progress

-recovery of classical texts (mathematics)-Renaissance pattern of patronage allowed

individuals to pursue scientific investigation(Galileo was supported by the Medicis)

-German astronomer -formulated the three laws of planetary motion -orbits of the planets are elliptical -velocity of a planet’s orbit is not uniform -time it takes a planet to orbit the sun is related to its distance from the sun -Kepler provided sound mathematical proofs for Copernicus’ heliocentric theory

Galileo Galilei (1564-1642)

-Italian philosopher and astronomer-viewed the physical universe as a “Book of

Nature…written in mathematical characters.”Improved on the telescope

allowed him to observe the motion of the planets and the surface of the sun and moon

-came to accept Copernicus’ idea of a heliocentric universe (based on observations)

-Galileo’s views were challenged by the ChurchChurch feared that helio-centrism would

undermine its authority and theologyBased on the geo-centrism of Aristotle

-Galileo was brought before the Inquisition works were banned and teachings were condemned

placed on the Index of Prohibited Books -he was threatened with torture and

excommunication and was placed under house arrest-Galileo recanted his views shortly before his death

-English mathematician – Cambridge University-built on the work of Copernicus, Kepler, and Galileo (Newtonian synthesis)-1686 formulated the mathematics for the

universal law of gravitation (every physical body in the universe exerts a

force on every other body)-proved that the universe was governed by precise

mathematical relationships

-Newton was deeply Christian (theistic) in his thinking

the physical order “can be the effect of nothing else than the wisdom and skill of a powerful ever-living agent.”

-the science of Newton would lay the foundation for the science of the western world

draw conclusions based on those facts (inductive reasoning-EMPIRICISM)-increase in knowledge would lead to powerful

nations and an increase in personal wealth
