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 a much larger scale. Fermi and Szilárd collaborated on a design of a device to achieve a self-sustaining nuclear reaction—a nuclear reactor. Owing to the rate of absorption of neutrons by the hydrogen in water, it was unlikely that a self-sustaining reaction could be achieved with natural uranium and water as a neutron moderator. Fermi suggested, based on his work with neutrons, that the reaction could be achieved with uranium oxide blocks and graphite as a moderator instead of water. This would reduce the neutron capture rate, and in theory make a self-sustaining chain reaction possible. Szilárd came up with
