CHAPTER 16
Scientific Revolution
What developments contributed to the
Scientific Revolution?


Renaissance humanists mastered Greek and were then
open to works of Galen, Ptolemy, Archimedes, Plato
Renaissance artists’ close observation of nature
established new standards for the study of natural
phenomena
Painters needed knowledge of geometry and anatomy
 Da Vinci declared mathematics integral to artists


Proliferation of books spurred innovation

Telescope, microscope
(divinity is in all aspects of nature,
magic, mysticism) inspired astrology and alchemy
Group Project





Seven groups (2-3)
You and your partner (or partners) will select a
committee from the list to give a brief report on
Summarize how your topic played a part in
Scientific Revolution and the emergence of modern
science
The report is to be two minutes and done with…
Sock puppets!

Presentation
Greatest Achievements in Sci Revolution:
, Mechanics, Medicine

Ptolemaic Conception:
center
 Earth
, earth at the
is made of earth, air, fire, water and always
changing
 Spheres that surround earth are crystalline, transparent,
and move in circular orbits (Aristotle said circle=most
perfect)
 10 bodies in all, our universe was finite with
God/Heaven beyond
Greatest Achievements in Sci Revolution:
, Mechanics, Medicine

Nicolaus Copernicus (1473-1543) polish
mathematician – not astronomer- used old models, own
computations
sun in center, planets revolve
around sun, moon revolves around Earth
 Kept circular orbits
 Waited until deathbed to publish, scared and embarrassed
 Created
uncertainty about human role in universe & God’s
location
 Protestants reacted harshly based on literal translation of
Bible
Greatest Achievements in Sci Revolution:
, Mechanics, Medicine

Tycho Brahe (1546-1601)
 Compiled
detailed records of observations and movements
of stars and planets
 Rejected Aristotelian-Ptolemaic system
 Unable to accept Copernicus

Johannes Kepler (1571-1630)
 Brahe’s
assistant
 Three laws
 Orbits
not circular but elliptical
Greatest Mustache in
 Speed of planet is greater when it is closer to sun History
(disproved
Nominee
Aristotle’s idea that motion is steady and fixed)
 Planets with larger orbits revolve slower
Greatest Achievements in Sci Revolution:
, Mechanics, Medicine

Galileo Galilei (1564-1642)
 Mathematician
used telescope to observe heavens
(1610)
 Planets
made of similar stuff to ours! Mountains and craters on
moon, moons revolving around Jupiter, phases of Venus, sunspots
 Stunned Europeans more than Copernicus and Kepler
 Firm believer in heliocentric system
 Roman
Inquisition ordered Galileo to condemn Copernicus
Greatest Achievements in Sci Revolution:
, Mechanics, Medicine

Galileo Galilei (1564-1642)


Written in Italian, making it more widely available, alarmed church
Found guilty of teaching Copernicus, put under house arrest
Aristotle held that an object
remained at rest unless a force was applied against it
and stopped when force stopped
What power was moving the planets?
 Galileo discovered
bodies stay in motion unless
deflected by external forces

Greatest Achievements in Sci Revolution:
,
, Medicine

Isaac Newton (1642-1727)

Invented calculus- mathematical means of calculating rates
of change
(1686)
Mathematical proofs for law of gravitation
 Three laws of motion





Apply to the universe- all can be explained through math


Every object in motion stays in motion until deflected
Rate of change of motion is proportional to force against it
Every action has an equal and opposite reaction
Gravity creates orbits
Widely accepted in England, not so much elsewhere
Isaac Newton
Presentation
Galileo vs. Newton


Collins Type II
Track the changes of the thought in astronomy from
Ptolemy & Aristotle to Isaac Newton
Medicine
Presentation
Greatest Achievements in Sci Revolution:
Astronomy, Mechanics,

Galen


Paracelsus (1493-1541)


Greek physician in 2nd Century CE influenced all others
applied chemical remedies “like cures like”
Andreas Vesalius (1514-1564)


blood comes from the heart (yes) two kinds of blood (no)
William Harvey (1578-1657)
Blood comes from heart
 all same blood in veins and arteries
 Blood makes complete circuit

New opportunities for elite women
emerged in Humanism

Margaret Cavendish (1623-1673)
 Aristocrat
taught in Humanist schooling
 Participant in crucial scientific debates
 Excluded from membership in Royal Society

Maria Merian (1647-1717)
 Entomologist

trained in her father’s workshop
Maria Winkelmann (1670-1720)
 German
astronomer, self and family taught
 Excluded from Royal Society
Women
Presentation
Opportunities for women in science
limited… by science
arguments about women
 Women
argued they were equal to men in ability
 18th century Anatomy “proved” women were designed
to bear children and excluded further from learning
and science
 Modern science saw a male takeover of traditional
roles for women like midwivery
DBQ


Analyze and discuss attitudes and reactions toward
the participation of women in the sciences during
the seventeenth and eighteenth centuries.

Scientific Method
Presentation
All answers can be found in reason

Rene Descartes (1596-1650)
 French
lower nobility, Jesuit education, studied
law
(1637)
I
think, therefore I am

Emphasis on the mind: only accept things that reason
proved
: duality between mind and
matter, the mind is separate and therefore can study
matter with reason
: reason and experience are chief
sources of knowledge
All answers can be found in reason

Francis Bacon (1561-1626)
: experiment and induction
: systematic observations and
experiments used to arrive at general concepts
Science & Religion
Presentation
Science and Religion

Benedict de Spinoza (1632-1677)

Could not accept separating the mind from matter or God from
science
God is not just the creator of the universe, he IS the universe
 Failure to understand God leads to many misconceptions
 Women were naturally inferior to women


Blaise Pascal (1623-1662)
Tried to convert rationalists to Christianity by appealing to their reason
and emotions- You can’t know everything, only God can
 God is a reasonable bet – if he exists, you win, if he doesn’t , you have
nothing to lose

