The SCIENTIFIC REVOLUTION, Explained [AP Euro Review—Unit 4 Topic 2]
TLDRThis script outlines the pivotal shift in understanding during the Scientific Revolution, challenging long-held beliefs about the universe and human body. It highlights the transition from geocentric to heliocentric models with figures like Copernicus, Kepler, and Galileo, who used math and observation to redefine astronomy. It also touches on the medical revolution, where Paracelsus, Vesalius, and Harvey debunked Galen's humoral theory, emphasizing empiricism and deductive reasoning in the pursuit of knowledge. Despite advancements, some old beliefs like alchemy and astrology persisted.

Q & A
What was the predominant belief about the universe in Europe before the 1500s?
-Before the 1500s, Europeans believed in the geocentric model of the universe, where the Earth was considered the center of the universe, surrounded by concentric crystal spheres with other planets and stars embedded in them.
How did the Catholic Church view the geocentric model of the universe?
-The Catholic Church approved of the geocentric model because it aligned well with the creation account in Genesis 1, reinforcing the belief that the Earth was at the center of the universe.
What were the three significant roots of the Scientific Revolution mentioned in the script?
-The three significant roots of the Scientific Revolution were the establishment of universities during medieval times, the Renaissance with its emphasis on realism and patronage of natural world studies, and the invention of the printing press which facilitated the rapid dissemination of new findings.
Who was the first key figure in the Scientific Revolution in terms of astronomy, and what did he propose?
-Nicholas Copernicus was the first key figure in the Scientific Revolution in astronomy. He proposed the heliocentric model, which stated that the Sun was at the center of the universe and that the Earth and other celestial bodies revolved around it.
What were Johannes Kepler's three laws of planetary motion?
-Kepler's three laws of planetary motion are: 1) Planets orbit the Sun in ellipses, not perfect circles. 2) Planets move faster when they are closer to the Sun and slower when they are farther away. 3) The time a planet takes to orbit the Sun is directly related to its distance from the Sun.
How did Galileo Galilei contribute to the Scientific Revolution?
-Galileo contributed by building his own telescope, which allowed him to observe the moons of different planets and prove that they were made of the same material as Earth. His observations were crucial in overturning the accepted truths about the universe.
What was the main challenge faced by scientists like Copernicus, Kepler, and Galileo during the Scientific Revolution?
-The main challenge faced by these scientists was that their work was overturning long-held assumptions about the cosmos, which were aligned with the Bible and therefore opposed by the Catholic Church, leading to conflicts with religious authorities.
Who was Isaac Newton and what was his major contribution to the Scientific Revolution?
-Isaac Newton was a key figure in the Scientific Revolution who combined the physics of Galileo with the mathematical computations of Kepler and Copernicus to produce the law of universal gravitation, explaining the force that kept planets in motion.
What was the humoral theory of the body proposed by Galen, and how was it challenged during the Scientific Revolution?
-Galen's humoral theory proposed that the body was composed of four substances or humors: blood, yellow bile, black bile, and phlegm. This theory was challenged by Paracelsus, who suggested that chemical imbalances, not humors, caused disease, and by Andreas Vesalius, who through dissection, debunked Galen's understanding of the body.
Who was William Harvey and what did he discover about the circulatory system?
-William Harvey was a physician who, through experimentation, discovered that the circulatory system was an integrated whole, with blood being pumped from the heart, traveling through the body, and returning to the heart to be recirculated.
What were the two major philosophical approaches to knowledge introduced by Francis Bacon and René Descartes during the Scientific Revolution?
-Francis Bacon emphasized empiricism, which is the pursuit of knowledge through inductive reasoning, starting with observations of the smallest parts of the world and generalizing to larger parts. René Descartes developed a system of deductive reasoning, which involved doubting everything that could be doubted and building reasoning upon undoubtable first principles.
Outlines
🌌 The Dawn of the Scientific Revolution
This paragraph introduces the shift in European thought from the pre-1500s geocentric model of the universe to the heliocentric model during the Scientific Revolution. It attributes the change to the establishment of universities, the influence of the Renaissance, and the invention of the printing press. The paragraph highlights the pivotal role of Nicolaus Copernicus, who challenged the geocentric view with mathematical evidence, proposing the sun as the center of the universe. Johannes Kepler furthered this with his laws of planetary motion, and Galileo Galilei provided empirical evidence using the telescope, which contributed to the acceptance of the heliocentric model despite opposition from the Catholic Church.
🔬 The Transformation of Medical and Astronomical Understanding
The second paragraph delves into the advancements in the understanding of both the cosmos and the human body during the Scientific Revolution. It contrasts the ancient Greek theories, such as the geocentric model and Galen's humoral theory, with the revolutionary ideas of Paracelsus, who rejected humoral theory in favor of chemical imbalances, Andreas Vesalius, who revolutionized anatomy through dissection, and William Harvey, who discovered the integrated circulatory system. The paragraph also touches on the methodological changes in reasoning, with Francis Bacon advocating empiricism and René Descartes developing deductive reasoning. Despite these innovations, some old beliefs like alchemy and astrology persisted, as exemplified by Kepler's work in horoscopes alongside his scientific laws.
