Though no printed copy of this lecture appears in Kurt's archives, a tape recording does exist, and now transcribed in written form, accompanies the digitized recording. This guest lecture was delivered at UC Davis in 1986 during the presentation of a replica of Duchamp's sculpture With Hidden Noise that had been created by UC Davis graduate student Tamara Blanken.
Of particular note here is Kurt's analysis of the secret object within the sculpture, and conjecture as to its nature. His "by the numbers" approach was used in his 1991, 350,000-word magnum opus in which he concludes the hidden object that makes the "hidden noise" is a six-sided die, such as used in playing craps. He does not disclose that conclusion in this lecture, but he does hint at it several times. Unusually, Kurt reads his lecture, rather than simply speaking extemporaneously, and at times sounds like he's hurrying; the tape (and transcript) ends before he did, unfortunately.
Kurt would appreciate, perhaps, that this lecture transcript was created via speech recognition software, and subsequently was corrected for accuracy by a human being.
