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.

Nuclear reactor new type of reactor using uranium came from the discovery by Lise Meitner, Fritz Strassmann and Otto Hahn in 1938 that bombardment of uranium with neutrons (provided by an alpha-on-beryllium fusion reaction, a "neutron howitzer") produced a barium residue, which they reasoned was created by the fissioning of the uranium nuclei. Subsequent studies in early 1939 (one of them by Szilárd and Fermi) revealed that several neutrons were also released during the fissioning, making available the opportunity for the nuclear chain reaction that Szilárd had envisioned six years previously. On 2 August 1939 Albert Einstein signed a letter to President
