The links to the lectures provide outlines of the material covered in each class. In some cases they have additional text and links covering supplemental material or graphics. I will attempt to make the online lecture notes are made available starting the week in which the lectures occur, but some notes may not be accessible until later in the week for various reasons.
Please feel free to print out copies of these lecture outlines in advance of class, so you can follow along with the lecture. Many students find this helps them listen without the pressure of taking down detailed notes of their own, but while still making additional notes in the margins to highlight particularly emphasized points.
See A Note about Graphics to learn why some of the graphics shown in the lectures are not reproduced with these notes.
Students looking to explore these topics further using the Internet might want to look at Prof. Richard Pogge's Selected Astronomical Internet Links for this unit.
