Expect a celebration of math, science, pastry and nerd pride at the Alferd Packer Memorial String Band’s annual Pi Day variety show, set for 7 p.m. Thursday at the Lawrence Arts Center, 940 New Hampshire St.

The fast-paced show will feature music, dance, standup comedy, film and feats, including a pi recitation contest where the highest number of memorized pi digits wins. Also planned is a pie-baking contest, with pies judged in flavor and creativity — though a pie that’s actually irrational and infinite would trump other categories.

Admission is $10 for adults, or $5 for students and seniors. Advance tickets are available through the Arts Center box office, 843-2787.
