a gallery at the Museum of Contemporary Art, Chicago under a slanted sheet of glass near a running wall clock. Burden planned to remain in that position until a museum employee prioritized his well-being over the artistic integrity of the piece. After 40 hours, the museum staff consulted physicians. 5 hours and 10 minutes after that, museum employee Dennis O'Shea placed a pitcher of water within Burden's reach, at which point Burden rose, smashed the glass, and took a hammer to the clock, thus ending the piece. By the end of the 1970s, Burden turned instead to vast engineered sculptural installations. In 1975, he created the fully operational B-Car, a lightweight four-wheeled vehicle that he described as being "able to travel 100 miles per hour and achieve 100 miles per gallon" ( and ). Some of his other works from that period are DIECIMILA (1977), a facsimile of an Italian 10,000 Lira note, possibly the first fine art print that (like paper money) is printed on both sides of the paper; The Speed of Light Machine (1983), in which he reconstructed a scientific experiment with which to "see" the speed of light; and the installation C.B.T.V. (1977), a reconstruction of the first ever made Mechanical television. In 1978, he became a professor at University of California, Los Angeles, a position from which he resigned in 2005 due to a controversy over the university's alleged mishandling of a student's classroom performance piece that echoed one of Burden's own performance pieces. Burden cited the performance in his letter of resignation, saying that the student should have been suspended during the investigation into whether school safety rules had been violated. The performance allegedly involved a loaded gun, but authorities were unable to substantiate this. In 1979, Burden first exhibited his notable Big Wheel exhibition at Rosamund Felsen Gallery. It was later exhibited in 2009 at the Museum of Contemporary Art, Los Angeles. In 1980, he produced The Atomic Alphabet – a giant, poster-sized hand-colored lithograph – and performed the text dressed in leather and punctuating each letter with an angry stomp. Twenty editions of the work were produced and are largely in the possession of museums, including SFMOMA and the Whitney Museum of American Art. 1988's Samson was a 100-ton hydraulic jack which was connected to a turnstile such that, with each guest who entered the Newport Harbor Art Museum, timbers were rammed
