Just curious of anything interesting that any of you might be working on. (anything is interesting, well almost?)
Me, I'm re-writing all of my notes which include old and new course & lecture notes, theories, problems, calculations, papers and any relevant or interesting stuff (also updated & calculated with latest data), organizing them to make it easy to replace anything that changes or to add anything new at its appropriate place (and, of course, to make it easier to look up anything). Gonna take a while but it'll be convenient, plus as a bonus, when I'm done I can slam a huge pile on your desk and shout "there, the universe, biatch!**
