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.

Aqueous homogeneous reactor hoped to design liquid-fuel reactors that would dispense with the costly destruction and processing of solid fuel elements. The formation of gas bubbles in liquid fuels and the corrosive attack on materials (in uranyl sulfate base solutions), however, presented daunting design and materials challenges. Enrico Fermi advocated construction at Los Alamos of what was to become the world’s third reactor, the first homogeneous liquid-fuel reactor, and the first reactor to be fueled by uranium enriched in uranium-235. Eventually three versions were built, all based on the same concept. For security purposes these reactors were given the code name "water boilers".
