The NOSE Have It! Topics: Brahe & Kepler Ellipses Keplers Laws
Tycho Brahe (1546-1601) Danish Nobility. Astronomer Had a nice mustache?
King Tycho? He built a castle with a HUGE observatory on the island.
Brahes Mission Brahe wanted to verify the Copernican model. He was in search of PARALLAX! He was able to collect tons of data without a telescope!
In the process…. He made observations of a supernova (nova = new star) in 1572. He made careful observations of a comet in 1577 and showed that it was further away than the moon. How did these observations and findings rock the Aristotelian theories?
Brahes Blunder? Ultimately, Brahe couldnt find any stellar parallax. As a result, he concluded (correctly) that one of the following must be true: 1.The Earth was motionless at the center of the Universe. 2.The stars were so far away that their parallax was too small to measure.
Brahes Universe Universe Chose to revert to a Geocentric model! Earth at the center….planets revolve around the sun!
Kepler (1571-1630) Mathematician Astrologist Astronomer Big on Copernican model!
Keplers Universe… Included the FIVE PLATONIC SOLIDS! Included SIX SPHERES…one for each of the six known planets! Sun at center!
