Lecture Topics

The lectures for this course are on Zoom.


These slides are by Jean Hakim. I have made some modifications/updates to them. Most of these slides were converted from PDF to PowerPoint and then back to PDF (the original PowerPoint was lost). The conversion process created some formatting issues, which I am slowly correcting.
