Mental Task 3: Cantor-Bernstein-Schröder Theorem
2007, 26:05 minutes, colour
This video is based on an ongoing series of video performances exploring the notion of mental tasks as a form of performance.
In Mental Task 3: Cantor-Bernstein-Schröder Theorem, a logician proofs a theorem of set theory on the blackboard.
In an interview with Mike Hoolboom, Gagliardi expands:
"In Mental Task 3: Cantor-Bernstein-Schröder Theorem, Imogen Dickie, who is a philosopher of language, is proving a theorem of set theory on the blackboard. She knows how the proof works, but she is working outside of her area of expertise, and hasn’t rehearsed the proof in a while, so she hesitates and makes mistakes. The film is a single take, and it ends when she manages to work out the entire proof. I didn’t want to film someone who could perform elegantly a well-rehearsed proof, I was looking for the struggle."
The video is also part of the installation Translations and Mental Tasks (Versions A, B, and C).
