  1. Scientific Revolution

  2. Scientific Revolution Scientific Revolution, when did it take place? No set date to indicate the start of the Scientific Revolution. Some historians the 12th and 13th centuries with the rediscovery of Aristotle by Europeans via the Islamic world. Others say it starts when Nicholas Copernicus challenges Ptolemy’s model of the universe.

  3. Scientific Revolution Polishamericancenter.org Nicholas Copernicus (1473-1543) -He based his helio-centric theory on Aristarchus of Samos (310-230 BCE). -The helio-centric theory during the time of Copernicus was not accepted because it meant rejecting Aristotelian thought. -His main work was On the Revolution of Celestial Orbs.

  5. Scientific Revolution Scientific Revolution, Why and how did it begin? Tables The tables used to predict astronomical events were not accurate. Exploration Spanish and Portuguese explorers to the Far east and America sailed off course and out of sight of land for days on end. The only people who could help them were the astronomers. Calendar The calendar created by Julius Caesar in 44 BCE was not accurate. The vernal equinox which was on the 21st had fallen to the 11th. Easter was based on when the vernal equinox fell. Therefore all religious holidays were based upon the timing of Easter

  6. Scientific Revolution NPR.org Nicholas Copernicus (1473-1543) On the Revolution of Celestial Orbs -Published, in the same year of his death, 1543. -Dedicated to Pope Paul III and caused little controversy. -It had an anonymous preface stating that it was only a mathematical hypothesis.

  7. Scientific Revolution Religious reasons For and Against Copernicus Theory What major social upheaval was taking place in the 16th century? Reformation Protestants—accepted helio-centric theory quickly Catholics—didn’t accept helio-centric as quickly.

  8. Scientific Revolution Copernican Theory Versus Ptolemy’s Theory Helio-centric Model Geo-Centric Model

  9. Scientific Revolution Geocentric Model of the Universe

  10. Scientific Revolution How did Copernicus’s Theory eventually dominate Ptolemy’s Theory? He believed the sun not only symbolized but also contained God. Arabic Numerals were adopted in Europe during the 12th and 13th century Which one is easier to do? MDMCXLVII x CCCLXXII OR 15147 x 372 Mathematical Astronomy, monks and students began adding, subtracting, multiplying and dividing. All of these calculations had proven Ptolemy wrong.

  11. Scientific Revolution • Scientists Supporting Copernicus’s Theory Galileo.rice.edu Tycho Brahe (1546-1601) A proponent of Ptolemy’s Theory. He made so many mathematical calculations that they became the basis for Copernicus’s Theory. Hear about his death and his nose here http://www.theworld.org/2012/11/tycho-brahe-not-poisoned/

  14. Scientific Revolution • Scientists Supporting Copernicus’s Theory Galileo Galilei (1564-1642) What brought about Galileo’s persecution? Telescope Galileo made his first telescope in 1609, modeled after telescopes produced in other parts of Europe that could magnify objects three times. He created a telescope later that same year that could magnify objects twenty times. With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. Doxologist.org

  15. Scientific Revolution • Scientists Supporting Copernicus’s Theory NPR.org Johannes Kepler (1571-1630) He also believed that the sun represented the spiritual essence and presence of God. Some of his laws were found in his 1609 work Astronomia Nova i) Planets orbited around the sun and remained in their orbital paths but revolve at different speeds. ii) Planets move in elliptical orbits iii) the speed of each planet’s revolution around the sun depends on its distance from the sun Read more about Kepler here http://www.npr.org/blogs/13.7/2013/02/04/171116703/keplers-genius-letting-nature-have-the-last-word

  16. Scientific Revolution Scientists Supporting Copernicus’s Theory Galileo Galilei (1564-1642) SidereusNuncius(The Starry Messenger)-1610 It was a pamphlet but his main work was Dialogues on the Two Chief Systems, 1632 This work forced the Catholic church to look at his work and how they related to Catholic teaching. Galileo Scripture he argued “teaches us how to go to heaven, not how the heavens go.”

  17. Scientific Revolution Scientists Supporting Copernicus’s Theory Galileo Galilei (1564-1642) After Dialogues On the Two Chief Systems of the World was published he was called to Rome to face the Inquisition. He was found guilty of heresy by 1633. His other work De Motuproved Law of Falling Bodies—Objects fall at the same speed regardless of mass. Aristotle believed heavier objects fell faster

  18. Scientific Revolution Revisiting Copernicus Paolo Antonio Foscarini A theologian in Naples, published a book which stated the Copernican theory did not conflict with scripture. The church took notice of Copernican Theory and places On the Revolution of Celestial Orbs on the Index of Forbidden Books

  19. Scientific Revolution • Scientists Supporting Copernicus’s Theory Isaac Newton (1642-1727) The Mathematical Principles of Natural Philosophy (1687) --Universe can be explained through mathematics --Universe operated in a rational and predictable way --Did not need religion or theology to explain the universe --All planets move by physical attraction, gravity Thenaturalhistorian.com

  20. Scientific Revolution Scientists Supporting Copernicus’s Theory Isaac Newton (1642-1727) Laws of Motion Inertia An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

  21. Scientific Revolution Scientists Supporting Copernicus’s Theory Isaac Newton (1642-1727) Laws of Motion Acceleration Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

  22. Scientific Revolution Scientists Supporting Copernicus’s Theory Isaac Newton (1642-1727) Laws of Motion Action For every action there is an equal and opposite re-action. http://teachertech.rice.edu/Participants/louviere/Newton/law1.html
