What happens when computer science, mathematics, pop culture and contemporary art meet? Join artist R. Luke DuBois and new media specialist Steve Dietz in a discussion to find out at 6 p.m. today (Thursday, Oct. 28) in 210 McKnight Art Center West. The two will examine DuBois' artistic work as a composer, performer, video artist and programmer. Specifically, they'll talk about his project and Ulrich Museum fall exhibition "Hindsight is Always 20/20," an artwork that uses algorithmic data to mine State of the Union addresses for clues to the nature and evolution of American political rhetoric.
