Julian Barbour on multiplicity.
[He] said that people overstate the role of reproducible experiments in classical physics, anyway. In practice, a single experiment can be plenty. Only in quantum physics does repetition become essential, because quantum theory is probabilistic and probability implies multiple instances.
It's best when the single experiment is reproducible. Plus
The philosophers in attendance tend to have training in physics, and the physicists, even if they can't tell their Hegel from their Heidegger, are eager to learn.
So there's hope then.
