So there was marking and stuff. I haven't marked a 300-level course in a while, so this isn't too bad. I just have to wonder why Menger's Theorem is so easy to misinterpret by these students...

Back to exercise again after a long break. Casualties: my left arm and my right fingers...

Some new photos posted on the photo gallery. There are pictures of Pittsburgh on the top level, and two new sub-albums under the Waterloo folder.
