BALTIMORE — Scenes from the University of Maryland, Baltimore County, campus, roughly 16 hours after its Retrievers pulled off the college basketball equivalent of the moon landing:

There are more geese than students roaming the paths on a cold, gray, drizzly Mid-Atlantic afternoon. Apparently, it’s spring break.

The light poles outside the student union are seemingly in fine shape, even though a handful of students shook them with delight after their team, a No. 16 seed, knocked off Virginia, the overall No. 1 seed in the N.C.A.A. men’s tournament, late Friday night about 450 miles south in Charlotte, N.C.

A theater marquee on the side of the locked student union gave equal billing to what had been coming activities.

3 14 Pi Day 12 p.m. MAIN ST 3 16 UMBC VS UVA 9:20 p.m. BASKETBALL HAVE A GOOD SPRING BREAK

Turns out Pi Day — the annual celebration of the number π, which falls on the date that can be written 3/14 — is serious business at U.M.B.C., which is primarily a science and technology school, possibly as serious business as a can’t-win N.C.A.A. tournament game. There is free pie.
