Lecture 1: Our Place in the Universe

1. Slide: Welcome: But I'm NOT Prof. Rebecca Martin. I just have her slides.
2. Slide: Bennett Textbook: See Canvas for instructor information about the textbook.
3. Slide: Watch the lectures: In intro astronomy, we mostly just look at images them and the instructor explicates. The other learning modes (reading and self-testing) are vital---in all courses.
4. Slide: Sylllabus: See Canvas.
5. Slide: Quizzes: See Canvas.
6. Slide: Exams and Final: See Canvas.
7. Slide: Our place in the universe: Note the foreground star---it has points and so is over-exposed.
