Johannes Kepler: A Geometry Project
Transcript of Johannes Kepler: A Geometry Project
8X8B Ms. Mayer Geometry Basically... Born Dec. 27, 1571 in Wuttemberg
Sick, poor, smart & religious kid
Had to move a lot because part Lutheran (30 yr war)
In Prague, went under Tycho Brahe's wing, inherited place after died
Died Nov. 15, 1630 in Regensburg
Central mathematician in 17th Century
Geometry God's mind "GOD IS A GEOMETER" Mysterium Cosmographicum (1597) Asked questions like: # of planets
orbit in proportion Answer - Platonic solids
When put in one another space in between proportion to planets
Made planet order & # clearer
Mars = oddball
Believed was part of God's plan "War on Mars" Found Mars & other planets' orbit elliptical
In Harmonies Mundi, velocity & orbit "musical" (perfectly geometric)
Believed that: 1. Caused by force (magnetism)
2. God planned it Kepler's Three Laws Planets have elliptical orbit
If line between planet & sun, planet will sweep out equal areas in equal time
Orbit of 2 planets can be in proportion with each other The Kepler Project Space observatory, similar to Hubble
Mission: Find terrestrial planets like ours
Detects exoplanets & solar systems
Hopefully, will find Earth-like planets and, possibly, life forms beyond our planet E N D T H E
