We have discussed earlier that the squash court at the University of Chicago offered the site of the first successful critical nuclear reaction in 1942 — thus implying a genealogical link between the material specificity of a sporting space and that required for this most uncertain of laboratory experiments. Chicago Pile-1, the mound of graphite bricks and wooden timbers that constituted the first nuclear reactor, found itself nested neatly within the squash court, the only place on campus with thick enough walls and a sufficiently elevated ceiling to house the experiment.
But it bears keeping in mind that a second architectural nesting takes place, the squash court proper being located underneath the bleachers at Stagg Field football stadium. In other words, the form of the stadium offered the space for a squash court, which thereafter offered space for Enrico Fermi and the Manhattan Project team members.
Put differently, a particular energetic system that is the football game becomes sufficiently popular when "converted" to or "expressed" as a semiosis that there is sufficient demand for larger-scale bleacher seating to be constructed. A new self-contained energetic system emerges in this fold: two bodies orbiting around a tiny rubber part-subject that pings around the concrete bunker, perhaps an allegorical metastability for the rupture that is to come.
