Conceptions of Space

(BEAUTIFUL GEEKERY) Each drawing by Lun-Yi Tsai (a Seattle-based artist who has been a research fellow at MIT) is based on a mathematical theory. Dan Pollack’s Wormhole Construction refers to Pollack’s discovery of how to construct wormholes between any two points of an Einsteinian space while maintaining its structure (well, you have to maintain the structure). In a talk this afternoon, Dan Pollack will elaborate on his mathematical theories of space. Painter Margie Livingston will discuss her artistic theories of space. Other math-art events will rock the gallery on Saturdays until June 2. (Shift Studio, 306 S Washington St, www.shiftstudio.org. 3 pm, free.) JEN GRAVES

Blue Scholars

(LOCAL HIPHOP) The current surge in local hiphop is primarily generated by Blue Scholars. There’s no doubt about that. The duo, Geologic and Sabzi, sell records, pack shows, rule the local airwaves, and are distributed by a Rawkus Records, the label that launched the hiphop underground in the late 1990s. Their latest CD, Bayani, makes one thing above all clear: Blue Scholars are getting better. Go to the show and see how Seattle does its own thing.
