Astronomy Lesson 12_02: Earth's orbit and tilt. The Seasons, the Year and the Day

Wherein we discuss the motions of the Earth, and reason for the seasons. This is the second of what I hope will become a long series of lectures. One of my major hopes with this series will be "modeling". When one teaches, one hopes to model what one expects from the students. Basically, it means, I want to show what riffing on a subject for 15 minutes looks like. I try to master the topic enough to do a "one-take" version of the lecture, just like you might get in a classroom. All of these lectures will be "one take". I won't do retakes, or do-overs, unless, of course, I get really knocked off my feet by someone coming in, or big noises or something. In this world, where Google searches, Siri queries, and Alexa echos dominate how we acquire knowledge, I am just hoping to show what it means to master a topic. In this case, introductory astronomy. You should try it too, on your own topic. I hope you enjoy!
