Moved on...

I assume that you've found this blog because you are taking Physics 102 at McGill University (or maybe another similar course elsewhere). I used to be a teaching assistant for this course and we experimented with using a blog format to interact with students. I have since moved to a new institution and will no longer be maintaining the blog. This means that I will not answer new questions. However, I will leave the blog here as a reference. You are welcome to browse around and look at previous questions that students posed and what answers I posted. You are free to post comments (unless things get unruly, or spammed) and discuss concepts with each other (to an extent which would not be seen as "cheating", if I notice this, I will simply shut down the comments sections). I encourage you to make use of the webCT discussion boards and the T.A.'s at your tutorials.

Best of luck!
