 Editing (and taking notes in) PDF files 
If you would like to take notes on your computuer, you may be interested in editing the PDF notes that I have available for distribution.  One great way to do that is to use Microsoft Office Onenote, which allows you to draw graphs as well as add text anywhere on a page.  This is quicker and easier than trying to edit the original powerpoint files. This handy note taking tools comes with academic versions of Microsoft Office.  You can import the PDF files into Onenote by opening the PDF file in Adobe Acrobat and then printing the file to the Onenote printer driver.  If you search the web for "Import files into notes with the OneNote print driver"  you should be able to find the instructions on Microsoft's web site for how to do that.

Printing PDF files
Many of the documents in my web page are in a format that requires the Adobe Acrobat Reader.  This is a zero-price (free) "plug-in" associated with your internet browser, and it needs to be installed seperately from your browser.   Many documents on the web -- documents that don't easily translate to HTML -- are in this format.  If you would like to install the Acrobat Reader on your own computer, you can do so by going to Adobe's website and download the "free plug-in" called "Acrobat Reader".
