Toward a New World View


 The Scientific Revolution
Introduction

   There were profound changes in the
    world-view of Europeans in the late 16th
    and early 17th centuries.

   The primary cause was the Scientific
    Revolution. (1543-present)
Introduction
                  The most
                   profound
                   change in
                   human
                   history?
Introduction
   The new intellectual climate differed
    from the medieval world-view:

       Rejection of authority.
       Best knowledge was practical.
       Demystification of the universe.
Introduction
   Intellectuals in this era differed from their predecessors by
    combining mathematics and experiment.

                    4 Elements:
                     Earth, water;
                     fire, air.
                    Uniform force
                     moved objects
                     until something
                     stopped it.
 The
 Great
 Chain
 of
 Being
Introduction

                  The Church
                   invested
                   greatly in this
                   world-view.
Nicolaus Copernicus (1473-1543)

   Polish monk.
   Observed patterns
    of star and planet
    movement.
   On the Revolutions
    of Celestial Bodies
    (1543)
The Scientific Revolution




     Heliocentrism
The Scientific Revolution
   Called into question the literal truth of the Scriptures.
   Copernicus waited to publish his findings.
The Heliocentric (Copernican) Universe
The Scientific Revolution

                    Niccolo Tartaglia
                     was the first to apply
                     mathematics to the
                     investigation of the
                     trajectory of
                     cannonballs.
                    His work was later
                     validated by Galileo's
                     studies on falling
                     bodies.
The Scientific Revolution
                   Gian Battista Benedetti
                    proposed a new doctrine of
                    the speed of bodies in free
                    fall.

                   The speed depends on the
                    difference between the
                    specific gravity of the body
                    and that of the medium it
                    falls through.
The Scientific Revolution
                   Tyco Brahe was a Danish
                    nobleman who set the stage
                    for modern astronomy by
                    building an observatory and
                    collecting data.

                   He was known for his
                    accurate and
                    comprehensive
                    astronomical and planetary
                    observations.
Galileo Galilei (1564-1642)
   Italian
    scientist.
   Improved the
    telescope.
   Formulated
    Laws of
    Motion and
    Inertia.
The Scientific Revolution
   Proved the
    Copernican view of
    the universe.
     Moon

     Planets

     Stars

     Sunspots

   Wrote in the
    vernacular.
Letter to the Grand Duchess Christina
    of Tuscany (1615)

   Written to address the
    conflict between the Bible
    and heliocentric theory.
   Argued that the Bible must
    be interpreted in light of
    scientific knowledge.
   Argued for a non-literal
    interpretation of the Bible.
   Galileo declared the Bible
    teaches how to go to
    heaven, not how the
    heavens go.
   The letter began Galileo’s
    troubles with the Church.
The Scientific Revolution
   1633 – Church arrested Galileo and charged him with heresy.
   He was forced to recant and was placed under house arrest.
The Scientific Revolution
   Johannes Kepler
    formulated three laws
    of planetary motion
    that proved the
    relationship between
    the planets in a sun-
    centered solar system.
The Scientific Revolution
René Descartes (1596-1650)
   French
    mathematician and
    philosopher.
   A transitional
    figure between the
    medieval past and
    modern science.
The Scientific Revolution
                    A rationalist.
                    Promoter of deductive
                     reasoning, predicting
                     particular results from
                     general principles.
Discourse on Method (1637)
   Descartes wished to
    develop a method that could
    be used to yield scientific
    truth.

   Argued that abstract
    reasoning and math were a
    more reliable path to truth;
    our senses could deceive us.

   Cogito ergo sum (“I
    think, therefore I am”)
The Scientific Revolution
                     Isaac Newton
                      integrated the
                      astronomy of
                      Copernicus and
                      Kepler with the
                      physics of Galileo.
Prinicipia Mathematica 1687
                  Newton formulated a
                   set of mathematical
                   laws to explain motion
                   and mechanics.

                  A key feature was the
                   law of universal
                   gravitation.
The Scientific Revolution

   Contributions
    made by these
    scientists made
    the universe
    comprehensible
    for the first time.
Scientific Revolution
   The individual became much more important;
    collective authority was not the source of
    wisdom…individual intellect was.
The Scientific Revolution
   After the
    Revolution, God
    was viewed by
    many as either a
    remote master
    mechanic, or his
    existence began to
    be doubted.
The Scientific Revolution
             Began long
              adversarial
              relationship
              between
              science and
              religion.
The Scientific Revolution
                  The Scientific
                   Revolution laid the
                   foundation for the
                   Enlightenment of
                   the 18th Century.

Editor's Notes

  • #3 -rejection of authority. Mostly Church authority, several crises contributed to this. -”best” authority was practical. Bacon: “purpose of knowledge was to ease man’s estate” Descartes: purpose of knowledge “to make us, as it were, masters and possessors of nature” Demystification of the universe: e.g., heavenly realm above the moon was no longer of eternal bodies that had no matter or weren’t physical Experiment was different from Observation, which the ancient did.
  • #11 The Church invested greatly in this world-view: put man in the center of the universe, most important part of God’s creation
  • #17 Called into question the literal truth of the Scriptures. There are a few passages where God, for example, makes the sun stand still. This implies that the earth is still and the sun moves around it.
  • #24 Among observations: moons of Jupiter, that is that there are planets with their own satellites: this also goes against the conception of perfect crystal spheres.
  • #30 Mathematician: invented the Cartesian Coordinate system and analytic geometry, among other things. Promoter of deductive reasoning . Wanted science to be like Euclid: deductions from self-evident starting points.
  • #32 Cogito ergo sum was one of Descartes’ “axioms”, that is, certain and self-evident truths that other truths could then be deduced from using a deductive method.
