- Universal Gravitation - a primer (Keynote presentation)
- Why do astronomy? Predicting events is power! Stonehenge (1400 BCE), Zodiac (1000 BCE), Kings hired astronomers to figure out events. During colonial times astronomy was the only science taught.
- Tycho Brahe's observatories.
- Given island of Hven by the king of Denmark and made very accurate observations of celestial bodies.
- Had a fake nose because he lost his in a duel over who was a better mathematician.
- Died at a party from a burst bladder.
- Kepler was Brahe's assistant. He wasn't much of an observer - childhood smallpox left him with weak vision but his ability as a mathematician was unrivaled. He first proposed elliptical orbits and took over some official duties Brahe had to some monarchs as court astrologer.
- Early models of the solar system
- Ptolemeic - epicycles, etc was geocentric with all circles. If we revolved around sun then star background would grow and shrink as we get closer and farther away in our orbit.
- Copernican - heliocentric with ellipses; phases of Venus sealed the deal that this is the way thing work. There is a huge problem with retrograde motion of Mars too.
- Copernican not accepted because priests and parents most trusted people in life - you just can't tell people they are wrong. (The same is true with former teachers.)
- Kepler's 1st and 2nd laws
- 6th/7th
- Finish centripetal motion examples
