Well, here we go with the first real physics lesson. Honestly, there's not a lot or physics here, but the background TO is quite interesting, so I hope you'll like this. In this lesson are two videos. They're a bit longer than my usual ones simply because they're the first ones and there's a bit of introduction. Along with my videos, there are going to be other helpful links in these lessons. One of these is this SCREENCAST. When you click on the word, it takes you to a different video by the book's author. Between the two of us, we'll get you through this course! Take a look at that, too, and then answer the quiz.
