portrait of the Ptolemaic System. Look particularly at the
following:
  Models for planetary motion: a geocentric view
with epicycles, and how phenomena of internal
planets can suggest a different setting. (avi-Divx, 20       Some other simpler animations of solar

Copernicus and Galileo




            Nikolaus Copernicus                                                                 Galileo Galilei
                (1473-1543)                                                                      (1564-1642)

                      Copernicus - 1473-1543

The world was not at the center of the solar system as the
Church and European traditions had taught for more than a
thousand years…

      “heliocentric” theories, which placed the

                            In spring 2012 the Portland Opera
                       staged a new opera by composer Philip Glass.

3 Keys on Road to the Scientific Skepticism
 Decline of faith in tradition and authority as the explanation of
 the way the world works!


              1493 - Columbus’s return changed earth
           1517 - Martin Luther’s protest changed faith
       1543 - Copernicus’s system changed universe


   What else was different between tradition and
                      reality?
Mathematics:
       The Language of the Universe
         by Galileo Galilei (1623)



Our universe “cannot be understood
unless one learns to comprehend the
language and read the letters in which it
is composed. It is written in the language
of mathematics…without which it is
humanly impossible to understand a
single word of it; without these, one
wanders about in a dark labyrinth.”
                         (The Assayer, 1623)
Learning How to Count

While addition of Roman numerals is not
complicated, multiplication of large numbers is.

basics of using Roman numbers.

The Church Was Right
?cience

• Comes from latin word scire “to know”
  or scienta “knowledge”
• In 1600s “scientific knowledge” less
  fallible than “common knowledge”
• Science as belief system embraces as a
  goal:
   – questions, not answers
   – doubt, not faith
   – ignorance, not knowledge
Science is always wrong
            (and that’s why it works)

“Religion is always right. Religion protects us
  against that great problem which we all
  must face.

“Science is always wrong; it is the very artifice
  of men. Science can never solve one
  problem without raising 10 more problems.”

                   George Bernard Shaw honoring
                  Albert Einstein, October 28, 1930
                                        (New York Times, March 14, 1991)
