what's the powerpoint of it all?

at the start of the semester's first class in continuous time finance the electricity went out. neither the students nor the instructors were able to figure out how to get the lights back on. see, the room is so advanced the lights aren't controlled by switches. switches are for third world countries. here in the developed world we have to get an "engineer" to unlock a control room, and turn some knobs and get the lights on for us. then we spend another 15 minutes trying to get the computer, the projector and the screens to work. technology helps us learn.
