Measure Theory Interblog

This semester, I was a teaching assistant for a third year economics course - mathematics for economists. Or economical mathematics, or something. The prof wanted me to attend the actual lectures so that I knew what was happened. But, they conflicted with my class, so I could only attend the first half and then leave in the middle. So, I’d usually get to see the introduction, or the motivation for what he was about to do, and then I’d have to leave. It was like every class was a cliffhanger than I never got to see resolved. Anyways, the prof assigned several homework questions and then added a few of his own (not from the textbook). The ones he made himself were to be solved using the “classroom version” of one of the textbook theorems. I missed the part of class where he mentioned the classroom version. And during the last 4 tutorial sessions, at least one person asked about these. So, I pretty much borrowed someone’s notes and winged it (wung it?). “Here’s how he said to do it…I don’t know why this works at all…Something he did in class, I guess…”

Someone just came up to me two minutes ago. He missed the review session. He wrote down the wrong day and wondered why the room was empty.  Anyways, he asked me that same question that everyone else asked. He seemed to be satisfied with my answer though.

Their exam is tonight. At the tutorials, some people were struggling with things they should have known from two years ago.
