Neutron trail — true and untrue — about nuclear energy and weapons. Enrico Fermi built the first nuclear reactor (Chicago Pile-1) in an abandoned squash court at the University of Chicago. He ran the historic experiment for 28 minutes. In April 2009 artist Matthew Day Jackson invited Olivia to participate in a ceremonial game of squash. Jackson and the younger Fermi’s game tied “the physics of a squash ball to the physics of the first nuclear reactor”; was filmed in Los Alamos, New Mexico and displayed in a 28–minute video loop at the M.I.T.

Enrico Fermi down once more a few hours later. The problem was traced to neutron poisoning from xenon-135, a fission product with a half-life of 9.2 hours. DuPont had deviated from the Metallurgical Laboratory's original design in which the reactor had 1,500 tubes arranged in a circle, and had added 504 tubes to fill in the corners. The scientists had originally considered this over-engineering a waste of time and money, but Fermi realized that if all 2,004 tubes were loaded, the reactor could reach the required power level and efficiently produce plutonium. In mid-1944, Robert Oppenheimer persuaded Fermi to join his Project
