This has been an odd summer and fall. Every since RUME4 class ended in May, I've felt... disconnected. From everyone and everything. I didn't realize the role that course sequence was playing in holding me together with my colleagues, but I guess it was. We said at the time that "one of these days we will really miss this exchange of ideas", but I certainly never thought it would be quite this soon. Absent that, it's hard to focus. I know this is the point at which a lot of PhD students flame out, but that knowledge doesn't make it much easier to fight the urge.
