Pendula, orbits, and the Society Of Physics Students picnic, believe it or not, all share something in common. They all have a periodicity to them. It turns out we're quickly approaching the end (or beginning, if you wish) of one of them, namely the yearly SPS Picnic. From time immemorial, the SPS has hosted a Spring Picnic at Lake Wauburg. The idea is to promote interaction among the professors, faculty, graduate, and undergraduate students outside the homely walls of NPB.
You may have noticed throughout the year that SPS is big on giving its members free food. This event more than any other highlights this giving characteristic. Professors and students use humanity's nearly perfected control over fire to create astoundingly delicious hamburgers, hotdogs, and other grill-related concoctions. Chips abound, cookies run a mock, and there are enough scrumptious beverages to keep a beached killer whale hydrated for weeks.
There's even non-food related fun. Frisbees whiz about, footballs and volleyballs hit the careless in the head, and, of course, the faculty gets dismantled by the superior students in the yearly softball game.
Of course it'd be impossible to have all play and no work, so SPS uses this opportunity to induct qualifying students
