... Along with that increased complexity came increased monetary costs and, sociologically most important, a significant increase in the scientific effort required to conduct an experiment. While Rod's early experiments involved two, three, and four scientists with a few technicians, and typically one or two scientist-years of effort, there are sixteen names on the first Fermilab paper, including seven from the Soviet Union, and those names represent perhaps twenty-five scientist-years of effort.
