Abstract
There has been a debate, among scholars, over whether Charles Augustin Coulomb
attained the results he presented in his and memoirs to the Paris Academy of
Sciences experimentally or theoretically. In an effort to contribute to this debate, we
study Coulomb’s famous electric torsion balance experiment of through a
historically more accurate replication than hitherto attempted, as well as through analysis
of relevant texts. In contrast to recent claims, we will show that (1) it has so far proved
impossible to obtain the same results reported by Coulomb in his paper of , (2)
Coulomb’s published results are most likely atypical, and (3) electric torsion balance
experiments degenerate quickly when parameters are gradually altered.
Acknowledgments
We wish to thank Jed Buchwald for generously making available to us the glass pieces of a torsion balance
identical to that used by Alberto Martínez. Thanks also to Eric Hatleback and Paolo Palmieri for their
important roles in replicating the elec
