NOTE: I removed Part A of this series of lectures (structure of the course) from the playlist because it is not really intended for non-ASU students. However, if you want to watch it, you can find it here: https://youtu.be/HKRZLJKPWFE

In this lecture, we examine the origins of orbital mechanics, starting from Aristarchus in 600BC and progressing through Ptolemy in 100AD. We focus on how models of planetary motion arose with and drove the development of technology, including mathematics, geometry, and even machine learning (if we interpret epicycles and deferents as function fitting).
